How to choose a good phone: revealing the secrets of making the right choice. How to choose a phone - The main selection criteria Selection of Chinese phones by parameters

Many people ask questions: How to choose a smartphone? How to choose a smartphone by OS? Smartphone screen - which one is right for you? How much memory should your smartphone have? - we will answer all your questions and consider what criteria you need to make a choice in 2019.

Smartphone- this is a convenient and modern device, but the disadvantage of all such gadgets is that they are short-lived and also very easy to break. What are we driving at? If you cannot choose a mobile phone, here are some good tips to help you spend your money on a truly multifunctional and high-quality item.

Why do you need a smartphone?

To choose a high-quality smartphone, you need to consider it from all sides, and that's what we'll do.
When it comes to choosing a phone, everyone feels like a real expert. At the same time, people do not take into account that opinions may not be the same. Indeed, think for a second - what do you need a smartphone for?
Today gadgets are produced for any age, gender and social status. Moreover, each device performs almost the same tasks. And it doesn't depend on the operating system.


A modern smartphone, in addition to making calls and sending SMS, has other important functions:

• surfing the Internet - now you can access the World Wide Web from anywhere in the world, having only a good phone;
• watching movies and listening to audio in excellent quality;
• work with office programs;
• communication via Skype and its analogues;
• solving everyday tasks.

It is very important to realize what exactly you need - all the provided functions or just calls with quick messages. If you do not use the Internet and do not watch all kinds of videos, then the smartphone will turn out to be unnecessary ballast. Buy yourself a simple cell phone with classic features and spend the savings on something more useful.

Which is better: Android, iOS or Windows Phone

It's time to choose the operating system for your smartphone. It depends on how convenient the functionality of the device will be for you, as well as the prospects for development, because new applications are constantly being released that can not be installed on any OS.
Android
One of the most popular and simplest operating systems. Going into any hardware store, you will see a variety of Android smartphones. That is why its main advantage is a large selection of models and manufacturers. If you are wondering how to choose an inexpensive but good smartphone, buy a device.


There is also huge software support for Android. As soon as you open PlayMarket and discover thousands of different programs that increase the functionality of the gadget, a flashlight is the most primitive thing you can install.


It can be concluded that Android, despite the pros and cons, is the most widespread operating system.
iOS
This operating system from Apple is designed for those who want a reliable smartphone. iOS offers the most functionality. What kind of bells and whistles can not be installed on an iPhone, there are both paid and free applications. This operating system offers users more than a million different toys and this despite the fact that almost every day something new appears. Apple phones are preferred by thousands of teenagers today.


But iOS is also not perfect, it has its pros and cons and is suitable for use only on Apple devices. Which operating system to buy is up to you.


As a result, we can say that it is more suitable for people who like ease of use and fast playback.
Windows Phone
If you trust Microsoft, then you will love this OS. Its main advantage is the ability to work on the phone in the same way as on a computer, this is mainly felt on Microsoft Office documents.


The disadvantage of such an operating system is its slow operation and a rather small number of applications compared to analogues. You should think about the choice of this OS.
Other
The list of OS is unlimited, Symbian, Bada, Blackberry OS - you can list it for a long time. Each of them has its own advantages, some take clients with functionality, others - with the speed of work.


These types of operating systems are considered the least common.

How to determine the screen size and resolution?

When you have already decided on a set of functions, it's time to move on to external parameters. Let's start with the screen size - what is the diagonal of the display for your smartphone?
Less than 4.5 inches
If you want the phone to fit freely in the palm of your hand and can be easily stuffed into your pocket, choose smartphones according to their characteristics with such a screen. These devices are also quite lightweight. The downside is that it can be difficult to type messages, especially if you have thumbs up.


4.5 - 5.5 inches
It is these smartphones in stores that are the most, they are the most convenient. These can be both cheap devices and phones with an average price. The larger the device, the less comfortable it is to hold it in your hand. However, if you like to play phone games or watch movies through a pocket gadget, then it is better to buy a device with a diagonal closer to 5.5 inches.


More than 5.5 inches
Phones with such large screens are called phablets. These devices are a cross between a smartphone and a tablet. You can operate such a device only with two hands, holding it with one and pressing the screen with the other. You can't put a phablet in your pocket, unless it's a huge pocket in your coat. Today, people talking on a smartphone with such dimensions no longer surprise anyone, so if you will not experience discomfort due to its large size, choose such a smartphone.

Memory Amount

You also need to be guided by the amount of built-in memory.
4-8 GB
If you plan to use it mainly as a regular phone and only occasionally access the Internet or play a few games, then this amount of memory is quite suitable. The fact is that the number of free GBs significantly affects the cost of the device, so think about it in advance. But more smartphones on the Android platform have the ability to insert a flash card.
16 GB
With that much memory, you should be able to fit some photos and music, but be prepared to run out of free GBs quickly.
More than 16 GB
32/64/128 GB is suitable for those who plan to actively use the device for different purposes. As soon as you open the same PlayMarket, you will immediately have a desire to download dozens of different applications, because each of them is unusual and necessary in its own way. In order not to fill up the entire RAM of the gadget in half an hour, take care of this in advance by calculating how many GB you may need.

Specifications

Processor power, amount of RAM and camera are the main characteristics of a smartphone. They are also the main choice.
Processor and RAM
The more cores a processor has, the faster and more powerful the smartphone. In theory it is, but in practice it does not always work out that way. It also depends on how optimized the operating system is. But all the same, more cores are not superfluous :)
The recommended number of cores is 2-4 or more.
RAM also affects the speed of your smartphone. 2 or more GB of RAM is recommended. The iPhone 7 costs 2GB.


But it is worth knowing that the smartphone slows down not on the number of cores in the processor and RAM, but also on other factors - the brand of the phone, the operating system, the year of manufacture, etc.
Camera
Everyone thinks and argues, when the more megapixels in the camera, the better it is. No, this is not entirely true. Megapixels - matrix resolution and image size. What is important in the camera is how each pixel is formed and the quantity and quality of the crystals in the camera. Apple has improved the camera every year only in the number of crystals, not megapixels. Maybe a smartphone has a 12 megapixel camera, and photographs like 3.2 megapixels. You need to check the camera personally.


Also, be sure to pay attention to the material from which the case is made, the type of screen, the manufacturer. All of these criteria will help you find the phone with the optimal ratio. Do not forget to check the reliability of the store where you buy the device - look for reviews about smartphones and stores on the Internet, ask your friends for advice, compare prices on different sites. Nowadays, it is much more profitable to order everything on the Internet, this does not affect the quality in the least, but the difference in price can be significant.

Today, there are a huge variety of different phone models, and when the question arises as to how to choose a phone, many are simply lost.

Yes, in online stores you can choose a gadget by parameters, there are even sites that take data from several stores and compare characteristics and prices.

But because of such an abundance of models, an ordinary person simply cannot understand which mobile phone is better and experiences real torments of choice.

To reduce them, below we will look at what criteria are usually used to select phones. After that, everyone will be able to understand what he needs and make the right choice.

Criterion # 1. Budget

Whatever one may say, but everything always depends on the amount of funds that we can spend on the purchase of a mobile phone.

Tip # 1: Before buying a new gadget, you should determine how much money you are willing to spend. After that, it will become clear what to expect.

In general, all phones can be divided into the following categories:

And if you need a phone just for this, then choose from models that cost up to 1000 rubles.

And the only characteristic that should be observed when choosing a dialer is the quality of the connection.

This refers to how clearly the voice of the interlocutor is conveyed. And here the phones from Fly stand out.

An example of a good dialer is Fly DS105C, which can be bought for 800 rubles. If you describe it in two words, it will be the words "affordable" and "simple".

Indeed, it will be very difficult to find an easier-to-use mobile device.

The battery is 900 mAh, which is enough for several days of operation without charging (276 hours in standby mode).

Its dimensions are only 110x45x14.6 mm - it fits very easily in your hand. There is a radio, an audio player and even a player for videos in mp4 and 3gp format.

In general, an ideal choice for those who have very little money in their pocket and who need a phone purely for making calls.

But it's still the 21st century, and if you buy a phone, you can dig in and buy something more interesting. Then you need to pay attention to all the criteria below.

Criterion # 2. OS (operating system)

The operating system is in every modern phone.

The most popular ones are:

1. Symbian. This OS today belongs to Nokia and, accordingly, is used only on the devices of this company. Now it is not nearly as popular as it was 4-7 years ago. And the following systems in our list are replacing it.
2. Android. Most modern phones run on Android. The OS is constantly being updated, improved, while it is often buggy and does not work the way the user wants.
   At least, this is evidenced by reviews on the Internet, left even in 2016. On the other hand, this system is the most demanded one, it is used by Samsung, HTC, Motorola and all Chinese phones, therefore they talk about it the most.
3. Apple iOS. A system designed specifically for Apple phones. There is nothing to discuss - buy an Apple phone, get an iOS.
4. Blackberry OS. Like iOS, it is designed for Blackberry phones only. This system is the record holder in this list, since it was created back in 1999.
5. Windows Phone. The developers tried to make an analogue of Windows 10 for computers with the same multi-colored icons of various shortcuts in the form of squares, only for smartphones. Very popular in the West.

Yes, there are many more different operating systems, for example OS Bada, Palm OS, Open webOS, Maemo and others. But it's better to choose from these five.

And the reason for this is that they are simply supported in our area, that is, if a phone on the same Android breaks, we will have it repaired, but it will be much more difficult to deal with a phone on OS Bada.

You will need to look for a master who would understand this issue, and this is very difficult.

So, the operating systems are defined. Now it remains to understand what kind of OS you want for your cell phone.

You should choose an operating system according to the following criteria:

1. Purpose of the smartphone. If he is needed by a business person who constantly works with documents and wants to customize the interface for himself, then Windows Phone will suit him, and if for games and all sorts of "gadgets", then definitely Android.
   If reliability is a priority, that is, a person does not care about games, but he wants to get a phone with which nothing will happen (for example, viruses will not beat it), then this is Blackberry OS.
2. Budget. If you don't have a lot of money in your pocket, but you want to get a good gadget, then choose Symbian. This OS is aimed at the budget class. But if money is not a problem, then you can spend money on Apple with Apple iOS.
   Android phones are a kind of golden mean.

Tip # 2: Best to look to the sideAndroid, because today most applications are written specifically for this OS. In addition, phones withAndroidare cheaper thaniPhone, but have almost the same functionality. And, after all, this is the most popular OS in our area.

Criterion # 3. Phone power

How powerful a phone is can be determined by the characteristics of the phone's processor and RAM.

CPU

This characteristic is related to the power of the mobile phone. The processor power is determined by its frequency. It is measured in Hertz (Hz) It is logical that the more, the better.

Today, the normal range for phones is 1–2 GHz (Gigahertz).

In addition, the power of the processor depends on the number of cores, each of which has its own specific number of Hz.

Interestingly, even on the most powerful modern smartphones, the number of GHZs rarely exceeds 2.5 GHz.

Only the Chinese masters stand out, who manage to fit up to 3.5 GHz into a regular phone. An example of such a phone is the ZTE Nubia Z9.

Considering the most expensive models and phones from the budget category, one can notice one interesting feature.

It lies in the fact that the processor power on budget smartphones is often more than on the most expensive ones.

This is quite logical, because manufacturers simply do not yet know how to make the processor more powerful.

Therefore, if it is important for you that the phone is powerful, you do not need to overpay.

An example of a really powerful device is the 2 GHz Xiaomi Redmi Note 3 in the processor. It costs about $ 230.

For comparison, the Samsung Galaxy S7 costs about $ 830 and has 2.3 GHz. Xiaomi also has 32 GB of internal memory, GPS, GLONASS and many other useful functions.

The disadvantages of the phone are only in a bad camera, a dull display (we'll talk about this later) and a non-removable battery - if it breaks down, you can't replace it on your own, and this is an additional inconvenience.

But Xiaomi Redmi Note 3 is one of the most powerful phones to date due to the next characteristic - RAM.

RAM

Another characteristic that affects power.

Measured in Gigabytes (GB). The number of GB determines how quickly the system can respond to user actions and process various operations.

So, in Xiaomi Redmi Note 3 these gigabytes are as many as 3. In the same Samsung Galaxy S7 there are already 4 of them, but it also costs an order of magnitude more expensive, as mentioned above.

There is no point in choosing a phone depending on the RAM, because with a powerful processor, no one will ever put a little RAM in the phone, otherwise the device will not be able to work correctly.

The bigger, the better.

Prompt: To understand how powerful the processor is, there is a handy program calledAnTuTu Benchmark.

In this program, each phone is rated according to its performance.

So, in early March 2016, a study was conducted that showed that the most powerful phones have a processor called Qualcomm Snapdragon 820.

In second place - Apple A9 (only for iPhone), and third place was taken by Samsung Exynos 8890.

1. Huawei Kirin 950;
2. Samsung Exynos 7420;
3. Qualcomm Snapdragon 810;
4. Qualcomm Snapdragon 652;
5. Apple A8.

Based on this, you can form the following advice.

Tip # 3: For a phone to be powerful, it must have one of the processors listed above.

But the problem is that such processors are not installed on budget smartphones.

Therefore, here is a hint for those who are looking towards state employees: Qualcomm Snapdragon 615, Mediatek MT6795 (aka Helio X10) and Qualcomm Snapdragon 801 also perform well.

An example of a phone with the most powerful Qualcomm Snapdragon 820 processor to date is the OnePlus 3 with 4GB of RAM.

The cost of such a pleasure is 500-600 dollars (so far the model has not yet been released).

Tip # 4: When choosing a phone, look at how much it dials in the programAnTuTu Benchmark(this information can be easily found on the Internet). This will make it possible to really see how powerful this or that model is.

Criterion No. 4. Working hours

How long the device can work depends on the battery. Battery capacity is measured in milliamps. Of course, the more, the better.

Roughly, phones with 2 GB of RAM and a 2 GHz processor should have at least 3000 mAh.

This will give the device the opportunity to work for about two days with a small number of games, a lot of Internet use and work with documents.

If you continuously play some heavy games, for example, GTA or Nova 3, then a device with a 3000 mAh battery will last about 6 hours.

But even the most powerful phones rarely have more than 4000 mAh. Yes, there are some "unusual" models with 5000 mAh, but they do not last long.

This can be seen very clearly in the example of the Bravis Power phone. The phone has 4500 mAh, but there is practically no power and, judging by the reviews on the Internet, the phone works for about 4-5 months.

It costs $ 115. The combination of such a price and such a battery capacity raises many questions. And for good reason.

From the above, we can conclude the following: if the phone costs less than $ 150, and the battery capacity on it is more than 3000 mAh.

This is very strange and such a device is unlikely to work for more than a year.

On the other hand, manufacturers often try to save on this parameter and try to use the processor, RAM and other parameters.

Yes, on budget phones, a capacity of about 2000 mAh is allowed. After all, all other elements there do not consume as much energy.

Therefore, you can deduce a certain golden parameter.

Tip # 5: The battery capacity should be between 2000mAh and 4000mAh.

Criterion No. 5. Built-in memory

This parameter determines how much data will fit on the phone.

Usually, manufacturers try to install no more than 16 GB on budget phones, while more expensive phones can have 32 GB or 64 GB.

But, looking at this parameter, only one condition needs to be taken into account - is it possible to use a memory card.

If you can insert an additional card, then a small amount of built-in memory is not a problem.

But it happens that this is not possible, and then the built-in memory will play the main role.

True, there is still an opportunity to use cloud storage, but then you will be tied to the Internet - if it is not there, then you will not see your files either.

Therefore, it is ideal that the phone has about 8 GB of internal memory and the ability to insert a memory card.

There is one more thing to say about the memory card. Often, manufacturers make a phone in such a way that it can accept 200GB - 1TB SD cards.

The fact is that if the phone contains too many files, about 100 GB, it will slow down and something will have to be deleted.

After all, even the most powerful processor and a large amount of RAM will not be enough to process such a large amount of information.

Accordingly, there is simply no point in too capacious memory cards.

Tip # 6: Choose phones with the ability to insert a memory card up to 100 GB.

Criterion # 6. Camera

It is very easy to check how high-quality and clear a photo is on a particular phone.

To do this, you need to photograph something and maximize some part of the picture, that is, apply the zoom function.

If the enlarged part of the picture is blurry, it turns out to be indistinct, it means that the camera on the phone is not of very high quality.

But sometimes there is no way to pick up the phone and “taste it”.

Then you need to look at two characteristics - the number of megapixels and the aperture.

Today, almost all manufacturers of phones and cameras are trying to attract people with the number of megapixels.

This value reflects how many pixels form the image. But not only this characteristic affects the quality of the picture.

The size of the aperture or relative aperture also affects. An example can explain the meaning of this quantity.

Imagine that you are in the country, it is raining and you need to collect as much water as possible in some containers.

If you put an ordinary mug with a diameter of 15 cm, then not very many drops will fall into it, and the water will collect slowly.

But if you put a large bowl with a diameter of 50 cm, more drops will get into it and the container will fill up much faster.

Likewise, the aperture reflects how much light enters the camera lens.

The aperture size is designated as “f / size”. In the figure, you can see the sizes of different diaphragms.

It becomes clear that the lower this number, the larger the aperture, respectively, the more light it can capture and the better the pictures will be.

Megapixels + Aperture

It is interesting that now on the Internet they write a lot about the fact that nothing depends on the number of megapixels and only the aperture affects the quality of the images.

In fact, this is not entirely true, because there were cases when developers, using this myth, put few megapixels on their phones, and made a large aperture, as a result, the pictures were not of very high quality.

Therefore, it is better to choose phones with the lowest f / value and the highest megapixel count.

On the other hand, it is very rare to find a phone with a large number of megapixels and a large “f /” value; manufacturers combine these parameters.

Samsung cameras show themselves very well in these parameters. In general, this company has a lot of its own technologies, one of them deals specifically with cameras.

The favorite in this regard is the Samsung Galaxy S6 with a 16MP main camera and a 5MP front camera.

To illustrate this, here's a shot of the night landscape taken with the iPhone 6.

And here is a shot of the same area taken with a Samsung Galaxy S6.

Agree that the photo taken with the Samsung Galaxy S6 is brighter and more saturated. After all, it has more resolution, which allows you to see the smallest details in the picture.

Tip # 7: When choosing a camera on your phone, be guided by the combination of megapixels and aperture.

At the same time, you should not pay attention to only one of these parameters, because often manufacturers, trying to deceive their customers, write only the number of megapixels or only the aperture (more often the first).

Criterion No. 7. Screen

Everyone wants the picture on the phone to be bright and rich too. But what to look for to choose such a phone? Brightness and saturation depend on four parameters:

• Diagonal.
• Permission.
• Pixel density.

Let's consider each of them in more detail.

Diagonal

This characteristic reflects how far from one corner of the screen to the opposite one. The figure below illustrates this distance.

The screen diagonal should be chosen depending on why you need a phone:

• for calls and basic functions - 3-4 inches;
• for Internet surfing and reading books - 4-5 inches;
• for games and watching movies - 5-6 inches.

Everything is very simple here.

Permission

The screen resolution is directly related to the diagonal in this ratio:

• for a diagonal of 3-4 inches, the resolution can be 480x800;
• for a diagonal of 4-5 inches, the resolution can be 960x540;
• for everything else, the resolution can be 1280x720 (HD), 1920x1080 (FullHD) and 2560x1440 (QuadHD).

Of course, the higher the resolution, the clearer the picture will be.

Pixel density

It is written as PPI (pixels per inch) and expresses how many pixels fit in one inch of the screen. It is clear that the higher this characteristic is, the clearer the image should be.

Usually manufacturers try to match the pixel per inch to the screen resolution.

So, on screens with a resolution of 1280x720 it can be up to 300 ppi. Basically, there is no point in choosing a phone depending on this characteristic.

You need to look at the previous two parameters - diagonal and resolution. Besides, the next parameter is also very important.

Screen type

Today the most popular types of screens are the following:

• OLED;
• AMOLED and Super AMOLED;
• AFFS.

In our area, you are unlikely to find phones with screens of the last two types, but in the West they are very popular.

It is very interesting that of the first three types, models with Super AMOLED screens show themselves best.

A phone with an HD resolution and a Super AMOLED screen will look much better than a model with a FullHD resolution and an IPS screen.

In particular, the viewing angles will be much better.

This setting means that you can look at the phone at almost right angles and still be able to see what is happening on the screen.

In the figure, you can clearly see a comparison of these two types.

This is especially true for Samsung phones, where many of their unique technologies are applied, so Samsung with Super AMOLED is much better than any other phone with Super AMOLED.

However, other screens look quite good, and you should pay attention to this characteristic only if the saturation and clarity of the screen is really important to you.

Tip # 8: If saturation and brightness are important to you, choose a phone withSuper AMOLEDscreen.

Here is another photo that confirms that it is best to choose Super AMOLED screens.

The leftmost phone here is Sony Xperia Z Ultra with TRILUMINOS screen, second - Samsung Galaxy Note 3 with Super AMOLED, then Sony Xperia Z1 with the same TRILUMINOS and last - Lg G2 with IPS.

You can clearly see that Samsung looks better than the rest.

Criterion No. 8. Phone Brand

As for which brand of phone to choose, the following provisions will help in this:

• If it is important for you that the phone can be repaired in our area, then these are Samsung, Lenovo, Fly, Prestigio, Asus, Philips, Sony, Lg. The fact is that in the CIS countries there are certified centers that carry out repairs.
  The rest of the phones will need to be sent for repair, most likely to China, which means that you will have to pay about $ 150 for shipping. It turns out that there is no point in the guarantee.
  You can, of course, find a local master, but then no one is responsible for the quality.
• If performance is important, then Xiaomi, Meizu, ZTE, Sony and the vast majority of other Chinese brands. In principle, Samsung also performs well, but it costs more.
• If a good camera is important, then Samsung, Sony, Apple, Lg, HTC, Lumia and some Lenovo models.
• If usability is important, then all phones are based on the Android operating system.
• If battery life is important, then DEXP, Fly, Philips, Highscreen, Lenovo and Samsung.
• If reliability is important (so that the phone does not break), then Sony, Samsung, Lg. Everything else most often fails after a year of use. Yes, if there are exceptions among the same Samsung, but basically, all models work for at least 5 years.
• If you don't want to spend a lot ("I want an inexpensive but good one"), then Xiaomi, Meizu and other Chinese brands.
• If you want to show that you have a lot of money, iPhone. The fact is that these phones do not have any special characteristics, but are expensive due to advertising. Therefore, you should only buy an iPhone when you just want to spend money.

In general, when choosing a brand, you need to focus on what is important to each specific consumer.

Criterion No. 9. Protective characteristics

I really want the phone not to crash, to withstand falling into water and other emergency situations.

Of course, you can cover your phone with covers, protective films, and generally wrap it in plastic and carry it in a velvet container, but you want the phone itself to be able to withstand at least a fall to the ground.

It is very easy to find a smartphone with a high degree of security - usually the characteristics say "IP ...", for example, "IP67". This means the level of protection.

By the way, the most secure phones have IP67 protection. Therefore, if you plan to drop your gadget frequently, it must have "IP67" on it.

An example of such a device is the Samsung Galaxy xCover S5690, which withstands being in water, being buried in the ground, and even being run over by a car!

Tip # 9: If the durability of your phone is important to you, choose devices with an IP67 rating.

But even without this level of protection, a mobile phone can be quite reliable if it has a special protective Gorilla Glass.

This glass is highly resistant to scratches and impacts.

With such glass, no additional protection is needed.

Of course, if the phone is run over by a car, the screen will crack anyway, but it will withstand a fall on an asphalt road calmly.

But even if the phone does not initially have such a protective glass, you can always buy additional glass.

But here it is important not to make a mistake and not buy an ordinary film, you need to choose glass!

Tip # 10: Choose a phone with Gorilla Glass protective glass, or buy additional glass with the phone right away.

Besides, when choosing a reliable phone, it is important to look at the material of the case.

The best thing, of course, is to buy devices with a metal case. But good plastic in a high-quality protective case will also withstand a hit to the ground.

Outcomes

If you want to hear the opinion of a specialist regarding what phones you can buy this year, then experts agree that the most interesting models in terms of all characteristics will be the following:

• Samsung S7- 4 GB of RAM, 2.3 GHz processor frequency, 32 or 64 GB of internal memory, a 12 megapixel camera and 3000/3600 mAh and, most importantly, a curved display.
  In principle, the popularity of the phone will be due to the unusual display. But all the other characteristics are encouraging. This pleasure costs about 900 dollars.

• Xiaomi Redmi Note 3 and Samsung Galaxy J7... The undoubted leaders of phones in the budget category (up to $ 300). Both have a 5.5-inch diagonal and 16GB of internal storage. Samsung has a 13 megapixel camera, but it shoots better than Xiaomi.
  RAM for Xiaomi is 2 GB, for Samsung - 1.5 GB. In AnTuTu, the first scores about 50,000 marks, and the second - 41,000. Samsung wins due to the better display. If performance is important to you, choose Xiaomi.

• Sony Xperia Z5. 5.1-5.9 inches screen (depending on modification), 28 megapixel main camera, 4200 mAh and resistance to immersion in water - all in the best traditions of Sony. The cost is about $ 800.

In this article, we will consider the choice of a smartphone - only important and really necessary information. A detailed description of the key points, tables of characteristics, ratings and diagrams will help you decide which smartphone is better to choose without overpaying for marketing noodles.

Most of the Internet epics, on the topic of how to choose a smartphone, start with secondary parameters: display, size, body material, operating system, battery capacity, price positioning, and an obsessive offer of certain models. About the most important characteristics of smartphones - either casually or with a pitchfork on the water. Why? This is understandable - initially, the lion's share of articles were written by online stores, and they, as you know, should be selling in the first place. Marketing gimmicks - big numbers where profitable, lots of pictures, emphasis on fictitious merits. An ordinary buyer loves shopping with his eyes and ears, this is exactly what he counts on.

How to choose a good smartphone in terms of parameters.

A smartphone is not just a phone, a beautiful trick with pictures, a smartphone is a computer, and as for any machine, the most important parameter is the engine. Do many people buy beautiful Ferraris with a Zhiguli engine? - that is the question. The engine, the heart of mobile devices, is the ARM chip, a set of microcircuits that includes: a processor, a graphics accelerator, a RAM controller, communication modules ... Everything that makes a “brick” a “living” mobile device.

It is better to start choosing a smartphone by examining the characteristics, computing potential of mobile ARM chips, and not the price or size of the gadget. It is the performance of the processor and video card of the chip you have chosen that determines how good the smartphone will be in solving certain tasks. Pay due attention to this parameter, especially if you want to choose an inexpensive smartphone with good characteristics.

ARM Chip! Processor + video card.

What do you need to know ?! ARM (Advanced RISC Machines) is the largest developer of 32-64 bit RISC processors for mobile and portable devices. ARM does not manufacture, but only develops and licenses technologies - it sells production rights to interested firms. Currently produced mobile processors (SoC crystals) are based on the ARM architecture. I recommend using the links provided, tables with characteristics of chips from leading manufacturers. Open and familiarize yourself with the models of SoC chipsets, it will help you understand what is written below - this is important and informative.

ARM chips have a cluster, block structure - the manufacturer has the right to choose the generation of the core, the number of cores and their class, the peak frequency, make improvements, make changes, and determine the final configuration of the crystal. Supply from 2 to 4 high-performance Cortex-A73 or Cortex-A75 cores plus 2 to 8 energy-efficient Cortex-A53 or Cortex-A55 cores, or save money and take from 4 to 8 as a basis Cortex-A53. In parallel, the configuration of the graphics processor is selected, the performance of which depends on the number of computing units -,. For example, in Mali-G72, from 1 to 32 computing units (from MP1-MP18-MP32 to) can be used, the GFLOPS column indicates the performance of one unit and the theoretical peak when all are implemented. Ultimately, all this determines the potential of a particular smartphone model.

Smartphones are priced at $ 40-80.
Most of the "modern" low-cost smartphones (low budget) are equipped with outdated Cortex-A7 chips (2013-2014) - MediaTek MT6570 / MT6572 / MT6580, Snapdragon 210/212, Spreadtrum SC7731 / SC8830, with a low-performance graphics accelerator Mali-400. I counted over 400 models from different manufacturers. By modern standards, these devices are ordinary "dialers" with very modest capabilities in terms of performance and corresponding usability. Calls, internet are good, games and resource-intensive software are sad.

Smartphones are priced at $ 80-100.
The next round of technological progress is represented by smartphones with processors - MediaTek MT673x / MT675x, Helio P10-30, Snapdragon 410-450, Snapdragon 610-630, Kirin 620-659, Exynos 7270-7880, which are based on the Cortex-A53 core (from 4 -x to 8). All this is flavored with graphics accelerators of different years and generations - Adreno or Mali. See the characteristics of mobile CPUs (number of cores, frequency) and GPU (GFLOPS), the corresponding links are suggested just above. This is a modern reasonable minimum for a smartphone that does not pretend to be a game console.

Smartphones starting at $ 100 for gaming.
When choosing a smartphone for games, pay special attention to the GPU graphics processor, in many respects the gaming capabilities of the smartphone, the quality of the displayed graphics, the smoothness of the picture, the number of fps depend on it. Last year, having a desire to make a gift to my godson (10-year-old school), I faced two conditions. First, from parents - to buy an inexpensive smartphone ($ 100), in view of age risks. The second, in secret, from the dreaming of a smartphone - so that you can play and games do not slow down. I listened to the first partly, the second became defining for me (do not disgrace myself in front of the boy).

I dismissed the mobile processors mentioned above (up to $ 100) right away, the characteristics of graphics processors and their performance do not correspond to the word gaming. Whatever one may say, choosing a gaming smartphone required going to the next level, and these are at least Adreno 510 or Mali-T830 / T880 / G71 / G72 MP3 video processors and higher. Among the variety of model lines Samsung, Asus, Sony, LG, Huawei, Nokia, Lenovo, Xiaomi, Meizu, Honor could not find a smartphone that would hook not only visually, but also have a good chip (CPU + GPU) for a reasonable price. It was the turn of the acquaintance with LeEco smartphones - here I was surprised and cheered up. The most interesting model was LeEco Cool1 - Qualcomm Snapdragon 652 (4 efficient Cortex-A72 + 4 energy efficient Cortex-A53) + GPU Adreno 510. Having studied the rest of the characteristics, I did not hesitate. The device works to this day, no defects and shortcomings were found, taking into account the price (up to $ 110 for Ali) - some advantages. The child likes the bright 5.5 ″ IPS screen and gaming capabilities, the parents were surprised by the camera with the Sony IMX258 sensor.

Guided by the opportunities of today 2018. and not forgetting about tomorrow's day 2019, I would start choosing an inexpensive gaming smartphone with models that have in their arsenal - Snapdragon 630 + Adreno 508, or even better - Snapdragon 636 + Adreno 509, Kirin 710 + Mali-G51 MP4, Helio P60 + Mali-G72 MP3, as an example of real models - Nokia 6, Xiaomi Redmi Note 5, Huawei nova 3i, Asus Zenfone 5, OPPO F7. Further on the rise, where the limiting factor for many will be not so much the characteristics as the price of the smartphone - Helio P70 + Mali-G72 MP4, Kirin 960 + Mali-G71 MP8, Snapdragon 660 + Adreno 512, Kirin 970 + Mali-G72 MP12 and pre-top Snapdragon 710 + Adreno 616 with new ARM architecture - 4x Cortex-A75 + 4x Cortex-A55. ...

Carefully study the characteristics of ARM processors, the speed of a mobile device, the availability of good cameras, audio-video processing, picture quality in games, ergonomics, and ease of use depend on them. The choice of processor - lays the foundation of the possibilities, from which all other "body kits" dance. Allows you to screen out thousands of device models and focus on 5-10 specs from different manufacturers. So it is much easier to decide and buy a smartphone with the really necessary parameters.

RAM and built-in memory.

With what amount of RAM and internal memory to choose a smartphone ?! The first value (operational) is a consequence of the choice of the processor, with the corresponding capabilities of the memory controller. For inexpensive dialers, this is 2GB of RAM. For smartphones with more efficient processors - at least 3-4GB of RAM, for those who like to install a lot of programs that hang uselessly in the background and 6GB will never be superfluous. 6GB and 8GB are more of a marketing gimmick at the moment than a real need to pump money out. Of course, it is better to have more RAM - the less, it would be a real benefit, and so, foolishly, you can score any volume to the eyeballs and shout, which is not enough.

The second quantity - the size of the storage (built-in) is a consequence of the operational needs of a particular user and the inherent capabilities of the smartphone manufacturer. Will you store your personal photo-video online or upload it to a PC, install several programs, 1-2 undemanding games - 16GB is enough. If your requests are more serious, we carefully study the characteristics of the smartphone, the parameter responsible for the presence of a memory card slot is important. The absence thereof is not a defect, but immediately raises the bar up to 32GB, 64GB is better if possible. When choosing a mobile device with a memory card slot, look at the supported maximum card size, the extra charge for a smartphone with an increased volume, and the price of a not the cheapest memory card with the corresponding volume.

Display type. Diagonal. Permission. PPI.

Screen... If the mobile device is not limited to one function - only to make a call, will be actively used in Internet surfing, have a gaming component, when choosing a smartphone, try to avoid displays with a TN matrix. Poor viewing angles (example in the picture), poor color reproduction, higher power consumption. The optimal solution is IPS matrices, devoid of the above-mentioned drawbacks.

A special place is occupied by AMOLED and Super AMOLED matrices, which have a number of advantages compared to IPS, but also not without drawbacks.

Advantages of AMOLED:
1) the use of OLEDs, eliminates the need for backlighting (lower power consumption);
2) power consumption tends to zero when displaying dark tones;
3) the response time of the matrix is ​​0.01 ms;
4) viewing angles of 180 degrees while maintaining contrast, chromaticity, brightness;
5) the thickness of the screen is reduced due to the lack of backlighting;
6) very high contrast.

Disadvantages:
1) lack of resistance to mechanical damage (breakage of contact, crack, puncture);
2) gradual burnout of LEDs, declared 6-10 years, but in lower-quality products, uneven brightness can be observed after a year;
3) the need to use PWM to eliminate the purple tint.
4) lower maximum brightness.

Diagonal... When choosing a new smartphone, try to rely less on your ears (someone said something), use your own brain more - the world is cognized by comparison. How many screams there were with the arrival of 5 ″ screens - a "shovel", but who needs one ... And what is the result? - we tried it, it turned out to be much more convenient than 4-inch ones. To date, the most popular are smartphones with a diagonal of 5 ″, followed by 5.5 ″ - 6 ″, and the ratio is changing towards more every day. The picture shows what the increase in the diagonals of smartphone screens in relation to 5 ″ results in - the average physical dimensions of real mobile devices, and not the screen itself, are indicated.

Depending on the model, there can be frames on the sides up to 3mm, top and bottom up to 15mm. If you have not had a large smartphone or are choosing one for the first time, and the store is far away, draw a rectangle on a piece of paper, so you can understand how comfortable the device will be in your hand. For versatile tasks, larger diagonal = better.

Permission... A large screen resolution of a smartphone - 1920 × 1080 and higher, in fact, is pure marketing with two goals. The first one, started as a bait, big numbers are always cooler and tastier for an ordinary buyer. The fact that many PC and laptop monitors, having many times a large area, do not reach 1920 × 1080, and no one has any problems with this, it is not surprising - they swallowed it. The second is to create a problem and then heroically solve it. The display resolution of 1280x720 is quite enough, but who asks us, the buyers…. We need to somehow justify the need to increase the power of ARM processors and force them to buy a new one. The growth of screen resolutions creates an additional, no, more truthfully and more precisely - an extra load. You can add support for VR (virtual reality technology) here, where support for high resolutions is important, but this is not the lot of smartphones, but powerful PCs. Concentrate better on choosing a sufficiently powerful processor for your smartphone - this is much more important, take the resolution for granted.

PPI- the density of pixels per inch - Pixels Per Inch - the number of pixels placed in an inch of the screen. Another secondary parameter imposed on us in the characteristics of smartphones, with a marketing background. Based on Apple research, the PPI value for smartphone screens should be around 300, at this value the human eye ceases to distinguish individual pixels (without a magnifying glass and microscope) from a distance of 300 mm. With a PPI of 400, only the very keen-sighted are able to find a pixel with their eyes buried in the screen. Conclusion, from 300 to 400 is good, everything higher is better, but the eye no longer sees it.

Bezel-less display... Another marketing gimmick for impressionable buyers, the frame has not disappeared anywhere, it just became a little smaller (before, the emphasis was on the thickness of the mobile phone). This is another imposed parameter that has nothing to do with quality, performance, or convenience.

Smartphone camera selection.

Choosing a smartphone, including how to replace a camera, do you need a good camera phone ?! - get ready, open the lid of the cerebral capsule wider. Choosing a smartphone model with a good camera on a swoop is quite problematic, there is also the magic of numbers. To understand, you need to know what it is and why you need it - megapixels, matrix size, size and number of pixels, aperture-aperture-aperture, type of autofocus, optical stabilization, camera sensor, lens quality in the camera, why dual cameras. Have you lost consciousness? - then we will continue, I will try briefly, about the main thing, in an accessible language.

Megapixel (Mp) Is 1 million pixels. Megapixels in the characteristics of the camera indicate the number of millions of light-sensitive elements (photodiodes - pixels) located on the surface of the matrix. With the increase in the number of megapixels, the maximum image resolution grows, but this does not guarantee an improvement in quality. Here comes into play - the size of the matrix and pixel (each of a million), look at the picture.

The larger the photosensitive element (pixel), the more it will be able to collect and convert light into an electrical charge, respectively - the signal is clearer and less noise. With a fixed area of ​​the sensor, we can accommodate 8 million large pixels or do marketing, cram 18 million very small ones. Notice how the inscriptions have decreased, the same happens with pixels when you try to cram the same million, but into a much smaller area. Due to the proximity - we get the diffraction effect, because of the small size - a decrease in photosensitivity, signal deterioration, an increase in noise, as a result - a lack of clarity, blurring effect. Since the size of a smartphone severely limits the size of the available matrices, balance is very important here.

Matrix size measured diagonally in Vidicon inches - equal to 16 mm. Smartphones can only dream of this size. Low-budget representatives are equipped with matrices 1/4 ″ - 16 mm divided by 4 equals 4 mm, mediocre ones with a diagonal of 1 / 3.2 ″ - 1/3 ″ (with many-many-mega-pixels), models claiming the title of camera phone 1 / 2.8 ″, real camera phones 1 / 2.6 ″ - 1 / 2.4 ″, the ultimate dream is 1 / 2.3 ″. But again, do not forget to link the matrix size with the number of megapixels and, as a result, the pixel size. Better 12 megapixels with 1 / 2.6 ″ (1.4 μm) sensor than 21 megapixels with 1 / 2.4 ″ (1.12 μm).

Pixel... In photomatrix pixels are measured in micrometers - "µm" in Latin or "µm" in the native and powerful. A good indicator for a budget camera phone can be considered a pixel of 1.22 microns in size. The cameras of today's best smartphones boast 1.25 micron, 1.4 micron, 1.55 micron pixels. There are also pleasant exceptions to the OnePlus 5 with a pixel size of 1.12 microns, but this is rather an example of how, due to good optics, the quality of sensors and competent automation, you do not disgrace yourself, but rise a step higher.

Aperture, aperture, aperture- a characteristic of the camera, indicating the size of the entrance hole, how wide the "eye" is, how much light will hit the sensor (matrix). Affects the picture quality in low light conditions.

A parameter from the series - the smaller the divisor, the better. It can take on the following values: f / 2.8 and f / 2.6 - very bad, f / 2.4 - bad, f / 2.2 - a tendency for the better, f / 2.0 - good, f / 1 , 8 and f / 1.7 is great, f / 1.6 is great.

Autofocus- the ability of the camera to direct focus, independently focus on the object. Contrast autofocus is a primitive and worst option. Phase - more intelligent, more efficient, faster. Laser autofocus - accuracy, speed, nice addition to phase detection capabilities.

Optical stabilization- compensates for vibrations, camera displacement relative to the subject being filmed - natural hand shake, shooting in motion. Increases exposure time - allows the camera to take a closer look (get more light-information).

Camera sensor... Today, the leading positions are taken by Sony photomatrixes, more than 40% of the market, Samsung sensors are in second place with 16%, closes the top three, somewhat inferior in class - OmniVision with 15% share. You can trust these guys, remembering to check TX before buying a smartphone -.

Lenses in the camera... The number of lenses does not indicate quality, as in fact, and the brand of the manufacturer as they are produced taking into account different market segments (ultra-budget, budget, etc.), with the corresponding tolerances, quality requirements. Unfortunately, you can only make sure of the quality during shooting.

Dual cameras... Why does a smartphone need dual cameras on the back? Initially, they quenched the obsessive desire to shoot everything in 3D. Today, the second camera can help you shoot at night, take panoramic shots, and realize optical zoom.

Let's summarize:
1. Megapixels - 12-13 MP - the golden mean.
2. Matrix size - 1/3 ″ is the minimum, 1 / 2.8 ″ is good, 1 / 2.3 ″ is ideal (for today).
3. Pixel size - for budget 1.12 microns, with a claim for good quality 1.22 microns and above.
4. Aperture - f / 2.2 so-so, f / 2.0 is the desired minimum, f / 1.8 is great, f / 1.6 is not better yet.
5. Autofocus - contrast - better than nothing, phase = good, phase + laser = great.
6. Stabilization is a very useful technology.
7. Manufacturer - study the above sounded characteristics.
8. Dual cameras - not necessary, better one good than two so-so.

Battery.

Although the battery capacity is a minor parameter, you shouldn't ignore it. The battery life, one way or another, will remind of itself, to a lesser extent during telephone conversations, to a greater extent - with the active use of Wi-Fi, Internet connections and games. When choosing a “dialer”, I would recommend not to go below 3000 mAh batteries, for entertainment mobile devices - from 4000 mAh and above. Real autonomy directly depends on a specific user, turn off wireless communications Wi-Fi, 3 / 4G, GPS when exiting, do not turn the screen brightness to maximum, study information about new firmware - you will be happy.

Fast battery charging... Whether your smartphone needs boost charging depends on your lifestyle. You have an ingrained habit of charging devices at night, the lack of this technology - you will not notice. Looking at the gadget, you see a game console - it will come in handy more than once. This technology has nothing fancy - you are offered a more "smart" charger that can adjust the output power, increase / decrease voltage and current, with constant monitoring of the battery temperature. From 0 to 50% capacity (15-30 minutes) - the battery is charged with high currents, then the power gradually decreases to minimum values.

One SIM card or two.

The number of SIM cards must be assessed according to two criteria. First, the human factor, everything is very clear here - two SIM cards are better than one. I am used to separating spaces - work and home (family, relatives, friends), I can always turn off the first one and enjoy life. The second, purely technical - about half of the smartphone models (budget and middle class) combine a second SIM slot with the ability to install a memory card - either a SIM or a card. What is more important is decided individually. You can buy a smartphone of the same model, but with a large amount of internal memory, for example.

Body material.

Metal, glass or plastic? I think you will agree with me ?! - smartphones are not created in order to sit on them or drop or throw them. None of the listed materials will protect you from damage. Metal body - three 50 each! About 50% of the market, 50% marketing, 50% has reasonable excuses, better heat dissipation, for example. In the production of smartphones, plastic inserts are used. The so-called glass case - more precisely, the glass back panel, 15% of the market, pure marketing, advantages in practical application 0. There are also ceramic, leather ... Plastic case - about 35% of the market, as a rule, this is the lot of inexpensive mobile devices. Apart from the cheapest smartphones, the material itself and its quality do not bring any inconvenience.

Operating system.

There is no cause for concern. There is actually nothing to choose here - either you buy an Apple iPhone with the iOS operating system, or the Android OS, choosing something from 3000 device models. The only recommendation is to avoid smartphones with Android versions 4 and 5, most likely you are being persuaded to buy an outdated byaka, in terms of processor and video card. For the rest, do not bother, the operating system, in no case, should affect the fundamental parameters - the choice of a graphics accelerator and processor.

This is actually all the important information accompanying a reasonable choice of a good mobile device. Try not to listen to sellers, decide which smartphone to choose according to the parameters, comparing the characteristics, this is the only way you will buy a smart that you can be proud of. It's not about the price and amount of money, but the ability to spend it wisely. Good luck!
