How to choose a cell phone based on parameters. How to choose the right smartphone based on parameters - expert advice. Minimum screen specifications

A smartphone is a rather complex and expensive device, practically inferior in characteristics to a desktop computer. Therefore, you should approach its choice thoroughly, but at the same time be prepared that not all your requests will be satisfied even by flagship models.

Many users prefer not to bother too much about selecting a smartphone model based on technical characteristics and, in order to avoid problems, simply buy a top-end device, expecting that, given its exorbitant cost, everything will be OK. Alas, even flagships (and sometimes just them) can greatly disappoint the owner, given high expectations.

Before choosing a model, you should formulate your preferences. The formulation “Everything should be fine” does not work here. Therefore, we put pluses in front of such requests as: I need expensive, medium or inexpensive, I need it for games and entertainment, I need it for everyday tasks, social networks and work, for calls and so on... little things, and so on until we run out conditions.

Based on the requirements received, you can already go to a communication store or simply open an online store website.

First of all, it's beautiful

As trivial as it sounds, the first thing most users choose is the design of the device. No matter how sophisticated a smartphone is, if you don’t like it, then owning it will not bring satisfaction.

But if the phone slows down or malfunctions, it will only bring you negative things. After this introduction, let's talk about the characteristics that are worth focusing on in order to get the best smartphone option for your needs.

There are too many processors

Indeed, the type of processor also determines the speed of the device, how quickly it responds when working with the interface and in applications.

It is important to remember that most modern mobile processors, whether inexpensive MediaTek Helio, Intel, Huawei HiSilicon, Samsung Exinos or Qualcomm Snapdragon, all provide approximately equal comfortable performance in the interface and when launching programs. Therefore, if you are not an avid gamer, then you should not rely on the latest super-powerful 12-core CPUs from the latest manufacturers. This way you will save about 30% of the cost of the device.

We can get acquainted with the operating features of the latest processors from Samsung in our article “”

How much RAM is enough?

Most modern smartphones from the mid-range and top-end segments are equipped with 3-4 GB of RAM. Low-cost smartphones come with 2GB. The larger this parameter, the more data your device can simultaneously process and the more running applications can be in memory. The system does not need to unload anything from the RAM to allow another more resource-intensive program to work. This adds speed and comfort.

For everyday use, when working with a browser and multimedia, 2-3 GB is enough. If you are used to working in several programs at the same time and love mobile games, then you should think about a phone with 4 GB of RAM. Devices with 6 and 8 GB can currently be considered a marketing ploy, which can be justified if you want to make a foundation for the future, when applications grow 3-4 times in size.

Flash memory: bigger is better

The amount of storage of user data on this disk and the number of installed applications depend on the amount of built-in flash memory.

Budget smartphones come with 8 GB of flash drive, of which only half is available to the user. This is unacceptably small and it is better to refuse such devices, even if they have a slot for memory cards. 16 GB (about 11 GB available to the user) and 32 GB can be considered acceptable. A good option is a smartphone with 64 GB of internal memory. This should be more than enough for programs and music with photos and videos.

We do not recommend targeting smartphones with 128 GB of internal space that are not equipped with a memory card slot. This is due to the fact that with a very large volume of the built-in disk, the user uncontrollably begins to accumulate a lot of personal data on it, especially photos and videos, forgetting to make a backup copy. If the device is lost or damaged, as a rule, the built-in disk also becomes inaccessible, which means all data will be lost.

In any case, if you value your data, do not forget to save it either to the cloud (this is convenient, but there is a risk of leakage), or to a PC or external drive.

A high-quality camera is the key to a good mood

The main trend in smartphone manufacturing in recent years has been improving the shooting quality of built-in cameras. First there was a race with megapixels (in one of the Nokia smartphones the camera produced images with a resolution of 40 megapixels), now every manufacturer considers it their duty to place as many cameras as possible on a smartphone. An unprepared user falls into a stupor when he sees advertisements that the smartphone is equipped with 4 cameras: 2 main and 2 selfies.

Some flagships have dual camera modules, in which the second one plays a supporting role to improve the picture. If this is presented to you as a super achievement that is worth paying extra for, treat it with reasonable skepticism. For high-quality photos, one camera is enough. The second can be wide-angle - this is a great opportunity to get more coverage in tight spaces. The main thing is that the built-in software processes the data coming from the photosensor well.

If you are looking for a smartphone with a good camera, focus on such parameters as matrix resolution - 13-16 megapixels (quite enough for detailed shots), high-quality optics, the presence of an image stabilizer (required) and aperture value. The last parameter is important for high-quality photographs in places with low light or in the evening and at night outdoors. It is advisable to have optics with an aperture of 1.8, but high-quality daytime images can be obtained with F2.0.

If the smartphone you choose is equipped with an F2.0 or F2.2 aperture, then the camera can compensate for the low illumination of the subject only with a long shutter speed and the optical stabilization function. The last parameter is very rare in budget smartphones, but is indispensable for obtaining high-quality photos and videos.

Capacious battery extends life

When choosing a smartphone as an everyday tool for work and entertainment, you should take care of a sufficient supply of energy. If the battery capacity of your chosen one is more than 3000 mAh, then this can be called the best option. This capacity is enough for two days of moderate use, despite the fact that the smartphone is equipped with a Full HD display. For an HD screen, the operating time of the device on a single charge can double.

In any case, you need to remember that a battery with a large capacity - 5000 or 6000 mAh, although it will extend the life of the gadget by a couple of days, but also weighs twice as much and takes a very long time to charge.

If you don't have time to fiddle with power adapter cords, choose a smartphone with wireless charging functionality.

Screen resolution: super small - not super convenient

The higher the resolution, the more image detail you will see. We recommend choosing Full HD screens if you have excellent eyesight and value high clarity of small objects, including in the smartphone menu. If your eyesight is impaired by books, games or age, then a display with HD resolution is quite enough. Are you planning to use a virtual reality headset to view 360 videos and 360-degree panoramas? Then you should choose a model with a screen resolution of 2K or QHD (2560x1440 pixels).

The size of the diagonal is an ambiguous thing. Some people need to control their smartphone with one finger, while others need a larger screen to have more information in front of their eyes. There is no single solution. Let's just say that taking a smartphone smaller than 5.5 inches is no longer fashionable today.

Additional options that matter

Among the important desirable characteristics, it is worth noting the presence of a 3.5 headphone output. Manufacturers are gradually abandoning it, but in vain. It is very convenient, especially if you often use your favorite wired headset. In the case of wireless headphones, you can tolerate the absence of a jack, but enjoy the versatility of the USB Type-C port.

Other parameters that you won’t see in the manufacturer’s specifications, but that are worth looking at, are interface convenience and reliability, which are measured empirically. It is also better to search for this information on the Internet.

In one of the articles we discussed the issue of screen locking on Android.

There are a huge number of models on the mobile device market. Go to the counter with gadgets in the cabin and see for yourself: thin, weighty, with a sophisticated camera and a fingerprint scanner, here the diagonal is 4 inches, and there as much as 5.5. And these are the technical characteristics, not counting the design. The buyer's choice, first of all, will be based on the phone's parameters, the combination of which will become the reason for the purchase. In our article we will analyze in detail what parameters there are, what you should pay more attention to, and how to choose a phone based on the main characteristics of the device.

Price issue

Phones can be divided into three large categories: budget models, mid-price devices and expensive models, the price tag of which starts from 25-30 thousand rubles.

A mobile phone under 10,000 rubles has long ceased to be a “worse, but cheaper” option. You can easily buy the gadget for 7-9 thousand, and the camera will produce clear pictures and the battery will not run out in a couple of hours. Manufacturers of inexpensive phones can save money by lowering the processor frequency and also not equipping the phone with a high-speed communication module.

It is worth paying attention to the latest phone models from Fly. Gadgets of this brand have long established themselves as the embodiment of a compromise between price and quality. Take a look, for example, at the model: compact body, 4.5-inch screen, 5-megapixel camera, LTE 4G module, has a position sensor, and costs 5,500 rubles.

The average price category includes phones from 10 to 25 thousand rubles. Manufacturers attract the attention of buyers with technical features. A mobile phone can have a fingerprint scanner, a dual camera, improved stereo sound technology, and the phone body can be made, for example, of metal with plastic inserts.

The price ceiling for “luxury” phones is limitless. Rest assured that for 30-40 thousand the manufacturer will try to put a “pumped up” filling into the case. For example, an eye tracking sensor. When the user looks at the screen, the phone increases the brightness, and when the user looks away, the brightness decreases. Some models, following the direction of their gaze, can even scroll text.

operating system

The type of operating system is directly related to the price tag. There are currently three main players in the mobile phone market: iOS, Android and Windows Phone. iOS is used only in Apple devices. Considering that the developer of the OS and the gadget are the same, when choosing Apple phones you can rest assured of their quality. Unique optimized applications are written for this operating system; the “axis” itself is characterized by high performance and reliability. The most noticeable disadvantage of Apple's operating system is that you have to synchronize with your computer through a separate application.

Android OS is without a doubt the most popular and in-demand operating system in the world. The open source system, for which hundreds of thousands of different programs are written, runs on a huge number of models of smartphones and tablets. Even cars and bicycles are produced on Android. You can choose and customize your Android phone by changing the shell and interface. Android mobile phones are available both for those who want to save money and for those who are not used to counting money.

But things are not going well for Windows Phone. There are significantly fewer applications for the operating system than competitors Google and Apple; analogues of popular programs like Instagram only disappoint because they lack the necessary functions. A large number of applications written for Windows phones cost a lot of money. Reading reviews about Windows Phones, one can come to the conclusion that the operating system is more suitable for business people who need quick access to documents under one shell and the main functions of the device.

Screen

Modern phones are equipped with screens based on three types of technologies: TN, IPS and AMOLED. The first two types use liquid crystals, while AMOLED screens are based on organic light-emitting diodes. TN displays are the cheapest, with a high response speed, but it’s difficult to look at such a screen at an angle - the brightness and clarity sags greatly. IPS screens, in this regard, are distinguished by color rendition, contrast and saturation and maintain maximum viewing angles of up to 178 degrees. AMOLED is an expensive technology, but phones with such displays consume less battery power, since they do not require additional lighting sources to operate. The picture itself on AMOLED displays comes out very contrasty and rich.

One of the important screen parameters is its diagonal. It is worth immediately determining for what purpose the phone is being purchased. If the gadget is used as a “dialer”, it is enough to choose a model with a screen larger than 4 inches. But games, surfing the Internet and reading books, of course, will require a larger screen: 5 inches or higher. In this case, it is worth paying attention to the screen resolution. On large displays, at least HD (720 by 1280 pixels), otherwise only pixels will be visible on the screen.

Speaking about Fly phones, it’s worth paying attention to one of the most popular Fly models of 2016. Here the screen is in perfect order: 5.5 inches, IPS technology and HD resolution with a high level of detail. On such a phone it is convenient to look at photo galleries on social networks and watch videos on YouTube.

CPU

Phone processors have three main parameters: the number of cores, frequency and amount of RAM. You need to focus on the tasks that the user will perform. If you constantly use power-hungry applications, launch games, videos and play music, it is better to take a phone with at least 4 cores, a clock frequency (from 1.2 GHz) and a RAM capacity of at least a gigabyte. If you don’t have to load your phone with multitasking, you can limit yourself to two cores with a frequency of 1 GHz.

The quality of optimization of the processor and operating system is directly related to the speed of the phone. Among processor manufacturers, the leaders are Qualcomm, MediaTek, Samsung and Intel. It is worth noting that MediaTek chipsets are considered balanced in terms of price-quality ratio.

Thus, the MT6735P is equipped with an optimized quad-core processor. The clock speed of the cores is only 1 GHz, while the phone easily copes with multitasking and responds instantly to touches.

Cameras

The quality of phone cameras is one of the parameters that the user looks at first. But what exactly determines the quality of a camera? First of all, this is the number of megapixels, the presence of autofocus, sensor sensitivity and aperture size. The flash can be ignored, since it is mainly used as a flashlight.

Choosing a phone based only on the number of megapixels is a misconception. Depending on the combination of the above parameters, an 8-megapixel camera can easily compete in image quality with, say, a 16-megapixel camera simply due to the fact that it may have a wider aperture and a light-sensitive sensor. This means the picture will come out brighter and clearer.

For example, let's pay attention to the optimal combination of camera parameters on the phone: 13 megapixels, autofocus, sensitive CMOS sensor and f/2 aperture. Thanks to this, the pictures taken come out very high quality, bright and clear.

Continuing the topic, you can watch a video tutorial on how to take a good photo with your phone camera:

Battery

With the phone parameter, such as battery capacity, everything is simple. The higher the capacity, the better. A powerful battery will allow you to work with your smartphone in active mode all day, while with a weak battery the phone will “fall asleep” after 3-4 hours. Please note that battery life is affected by factors such as screen resolution, operation of Wi-Fi and GPS modules, resource-intensive applications, and active surfing on the Internet. Reading the reviews, you can come to the conclusion that the optimal capacity for stable operation is 2500-2800 mAh. In this case, the phone will ask for charging no earlier than after 7-8 hours.

Can Fly offer a device with a powerful battery? Certainly! Pay attention to the model. This is the first phone from the British manufacturer to receive a 4000 mAh battery. Considering that the smartphone has a large display on an IPS matrix with excellent color rendition and HD resolution, Nimbus 12 has become a phone with an impressive operating life: up to 15 hours of uninterrupted operation with the main functions of a smartphone, up to 7 hours of work on 3G Internet, up to 8 hours of WI-FI network, 8 hours of video playback and up to 70 hours of audio playback.

Buying a cell phone is an important and responsible step. It is better to read reviews and testimonials from ordinary users, and then choose the model that is right for you.

average price: 12,600 rub.

This is a real discovery among models in the mid-price range. The manufacturer focuses on the quality of assembly and components. A pleasant opinion is formed about the metal, almost “indestructible” case, which is becoming increasingly rare. Due to its thinness and rounded edges, the gadget is pleasant and comfortable to hold in the hand, despite the diagonal being above average at 5.5 inches.

Buyers of the Xiaomi Mi A1 64GB smartphone like the wide brightness range and good viewing angles, calm color rendering and the screen protection with impact-resistant glass, which increases its service life. The gadget works flawlessly even when several applications are open at the same time, and it can handle almost any game, although the quality of the graphics in them leaves much to be desired.

Average price: 13,000 rub.

The best phones with good quality under 20,000 rubles

An assortment of models costing 15,000-20,000 rubles. the most diverse and interesting, here you can already count on some “tricks” and technological delights. Evidence of this are the 3 models included in this category.

With the release of this smartphone model, the popular company Apple did not lose face, but did not offer anything new. The characteristics of the smartphone are average, with good build quality and the same functionality. A 12 MP camera, a fingerprint scanner, and a 1624 mAh battery are hidden in a compact metal-glass body. At the same time, the device weighs only 113 g and is not felt in your pocket. Its screen is small and clearly aimed at women, as evidenced by its 4 inches and white color.

The Apple iPhone SE 32GB smartphone model is traditionally equipped with a proximity sensor, which allows you to avoid accidentally dropping a call during a conversation thanks to automatic screen locking. Thanks to NFC, you can exchange information with other devices over a short distance. To store it, the built-in memory of 32 GB is quite enough.

What is the best quality phone to buy?

An important criterion for choosing a smartphone is battery capacity. If you do not plan to play games on your phone, listen to music often and surf the Internet a lot, then good inexpensive mobile phones up to 3000 mAh will be enough. For the tasks listed earlier, more powerful gadgets will be needed, and it is desirable that they have more than two cores in the processor. Those who want to take photos with a smartphone should choose options with a camera of at least 12 MP.

Before you finally make your choice, you should pay attention to the following tips:

• For selfie fans, the Huawei P20 Pro is the best choice.
• For active calls and listening to music, you can choose Huawei P20 Lite with a capacious battery.
• Gamers should pay special attention to the Samsung Galaxy A6 and Samsung Galaxy J6 gadgets released in 2018.
• For those who want to emphasize their high status and have a large budget, a good choice would be the Apple iPhone SE or Apple iPhone 8 64GB.
• Teenagers can buy the Xiaomi Mi A1 64GB, which works great and is not very expensive.
• Those who often drive should take a closer look at the Samsung Galaxy S9.
• For women, the ideal option is the LG X power K220DS and the Samsung Galaxy J2 Prime SM-G532F in white.

Currently, three platforms are leading the market: Android, iOS (iPhone) and Windows Phone; they are preferred by the majority of buyers. BlackBerry is trying its best to compete with the other three operating systems, but so far in vain. Let's briefly look at the strengths and weaknesses of each OS.

Android

Google's OS is one of the most popular platforms for smartphones. Compared to iOS and Windows Phone, there is a much wider range of devices on this platform from a number of manufacturers (Samsung, HTC, LG, Motorola, ZTE, etc.). Android is more open system, meaning it's easier for smartphone makers to innovate on Google's software. That's why the Samsung Galaxy S4 or Note 3, for example, can have two apps open on the screen at once, and the Moto X can be controlled by voice without having to touch the phone. You can buy the smartphone from the article on RBT.ru.

The Google Play store has more than 1 million applications, which means you can find almost everything you want, but Apple's App Store tends to be the first to receive hot apps and games. We love Android's flexibility and customizability, but some interfaces can be cluttered and easy to get lost in.

IOS/iPhone

IOS 7 has included significant improvements from Apple. The appearance has become even neater, multitasking has improved, and a new Control Center has appeared for quick settings. Some aspects of the update are confusing, such as the Notification Center being split into three separate tabs, but overall, iOS remains the most intuitive smartphone platform. Apple also leads the way in having a diverse selection of high-quality apps and games (though Android is closing the gap). The Siri voice assistant has improved and the emergence of the new iTunes Radio music service is a definite plus.

Windows Phone

More and more people are paying attention to Microsoft's OS, mainly thanks to Nokia Lumia phones. The platform features a dynamic interface with “live tiles” that display updates. These tiles are easily customizable, you can choose from three sizes, move them, add and remove them. Other benefits of Xbox include games, videos and music, and integrated Microsoft Office Outlook. The number of applications in the Windows Phone store recently exceeded 200,000, including applications for Instagram. But Microsoft's platform still has about one-fifth of the software available for Android and iOS.

2. Choosing the size of the smartphone: phablet or non-phablet?

The demand for phones with large screens is growing. The share of smartphones with displays of 5 inches and larger, the so-called phablets (English phablet from PHone + tABLET - a marketing term denoting a class of mobile devices with a touch screen diagonal from 5 to 7 inches), currently accounts for about a quarter of all smart devices sold telephones." Although the iPhone 5S with a 4-inch screen became the best-selling smartphone in the United States. The smaller display contributes to a more compact design. If you want something big, choose from Android or Windows Phone models.

The 5.7-inch Samsung Galaxy Note 3 provides a large surface area for viewing photos, movies and games. The trade-off is that it's not that easy to hold with one hand. Phones with even larger displays, such as the HTC One Max (5.9 inches) and Nokia Lumia 1520 (6 inches), tend to be heavier and won't fit into every pocket. But there are people who are willing to put up with a larger size, especially those who do not want to carry a tablet with them as well.

3. Pay attention to these characteristics

CPU

The phone's processor is the brain of the device and its speed will allow you to open applications without delay, play games smoothly and even edit videos. The modern chip for Android and Windows Phones smartphones is Qualcomm Snapdragon 800 (soon 805). This processor powers fast multitasking and powerful graphics in devices like the Galaxy Note 3 and Lumia 1520.

The Snapdragon 600 (in the HTC One) and S4 Pro (in the Moto X) are also very capable. Less expensive phones use the Snapdragon 400 processor, which is powerful enough for everyday tasks but not designed for more active activities. For example, the Galaxy S4 Mini with this processor took 7 minutes and 19 seconds to transcode a 1080p video, compared to 5 minutes and 15 seconds for the Snapdragon 800 that powers the Galaxy Note 3.

Apple's 64-bit A7 chip powering the iPhone 5s offers nearly twice the performance and graphics performance of the previous A6 chip (in the iPhone 5c). This is just one reason why it's worth investing in more expensive Apple devices.

RAM / Random Access Memory

The amount of RAM significantly affects the performance of a smartphone. Modern flagship devices offer between 2 and 3 GB of RAM, while the lower limit for mid-range phones hovers around 1-1.5 GB. If you want to quickly load applications and quickly switch between them, then the more RAM, the better.

Screen

Screen brightness.

Screen size definitely matters, but so do brightness, sharpness, color, and viewing angles. Currently, the sharpest screens for smartphones are 1080p (1920 x 1080 pixels). However, there are 720p (1280 x 720 pixels) displays, such as those on the Moto X, which offer excellent image quality. To evaluate viewing angles, we recommend holding the smartphone in your hand and seeing how much the image fades and blurs when the device is tilted.

You may also want to consider this: AMOLED screens (common to many Samsung phones) tend to produce very rich and saturated colors, while LCD displays generally offer more realistic hues. It all comes down to personal preference here.

Built-in memory capacity and its expansion

Considering that you will store everything on your smartphone - from photos and music to videos and applications - you should choose as much memory as possible. Although 16GB is a fairly standard capacity, 32GB of memory is the most preferable choice. For example, an iPhone 5S with 32GB memory costs about $300. There are also more affordable options, including HTC One with 32 GB, its price starts from about 200 USD.

Also, to increase the amount of memory, you can choose a device that has a slot for MicroSD cards, for example, Samsung Galaxy S4, Note 3 and Mega.

4. Smartphone camera (don’t pay too much attention to the number of megapixels)

The fight for megapixels is over, but there are still a handful of smartphones whose cameras have a resolution of 20MP or higher. However, it should be understood that the quality of the image sensor itself is more important. For example, the iPhone 5S was equipped with an 8MP camera, but a new sensor with larger pixels allows you to create clearer images.

Camera functions

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

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

But due to such an abundance of models, the average person simply cannot understand which mobile phone is better and experiences real agony of choice.

To reduce them, below we will look at the criteria by which phones are usually selected. After this, everyone will be able to understand what they need and make the right choice.

Criterion No. 1. Budget

Whatever one may say, it always comes down to the amount of money that we can spend on buying a mobile phone.

Tip #1: Even before purchasing a new gadget, you should determine how much money you are willing to spend. After this it will become clear what to expect.

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

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

And the only characteristic that should take place when choosing a dialer is the quality of communication.

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

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

Indeed, it will be very difficult to find a mobile device that is easier to use.

It has a 900 mAh battery, 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 video player in mp4 and 3gp format.

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

But this is the 21st century, after all, and if you’re going to buy a phone, you can save up and buy something more interesting. Then you need to pay attention to all the criteria below.

Criterion No. 2. OS (operating system)

Every modern phone has an operating system.

The most popular of them are:

1. Symbian. This OS today belongs to Nokia and, accordingly, is used only on devices from this company. Now it is not nearly as popular as it was 4-7 years ago. And it is being replaced by the following systems on our list.
2. Android. Most modern phones run on Android. The OS is constantly updated and improved, but 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 popular, it is used by Samsung, HTC, Motorola and all Chinese phones, which is why they talk about it the most.
3. Apple iOS. A system designed specifically for Apple phones. There is nothing to discuss here - buy an Apple phone, get iOS.
4. Blackberry OS. Like iOS, it is designed only for Blackberry phones. This system is the record holder on this list, as 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 down, we will fix it, but with a phone on OS Bada it will be much more difficult to figure out.

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

So, the operating systems are defined. Now all that remains is to understand what OS you want for your cell phone.

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

1. The purpose of a smartphone. If it is needed by a business person who constantly works with documents and wants to customize the interface for himself, then Windows Phone is suitable for him, and if for games and all sorts of “bells and whistles,” then definitely Android.
   If reliability is a priority, that is, a person does not care about games, but he wants to get a phone that nothing will happen to (for example, viruses will not attack), then this is Blackberry OS.
2. Budget. If you don’t have a lot of money in your pocket, but 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: It's best to look awayAndroid, 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 No. 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 power of a processor is determined by its frequency. It is measured in Hertz (Hz). It is logical that the more there are, the better.

Today, the normal rate 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 GHz frequencies rarely exceeds 2.5 GHz.

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

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

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

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

Therefore, if it is important for you that the phone is powerful, you don’t have to overpay.

An example of a truly powerful device is the Xiaomi Redmi Note 3 with a 2 GHz processor. It costs about 230 dollars.

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

The only drawbacks of the phone are a poor camera, a dull display (we'll talk about this later) and a non-removable battery - if it breaks, 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 today due to the following 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 there are as many as 3 of these Gigabytes. In the same Samsung Galaxy S7 there are already 4 of them, but it also costs an order of magnitude more, 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 little RAM into a phone, otherwise the device will not be able to work correctly.

The bigger, the better.

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

In this program, each phone is given a score based on its performance.

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

In second place is the Apple A9 (for iPhone only), and the third place is taken by the 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, we can formulate 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 tip for those who are looking towards budget devices: 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 RAM.

The cost of such pleasure is 500-600 dollars (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 give you the opportunity to really see how powerful a particular model is.

Criterion No. 4. Working hours

How long a device can operate depends directly on the battery. Battery capacity is measured in milliamps. Of course, the more there are, the better.

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

This will give the device the ability 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 3000 mAh 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 don’t last long.

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

It costs $115. The combination of this price and this 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 its battery capacity 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, budget phones allow around 2000mAh capacity. After all, all other elements there do not consume so much energy.

Therefore, we can derive a certain golden parameter.

Tip #5: The battery capacity should be from 2000 mAh to 4000 mAh.

Criterion No. 5. Built-in memory

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

Typically, manufacturers try to put no more than 16 GB on budget phones; more expensive phones can have either 32 GB or 64 GB.

But, looking at this parameter, you need to take into account only one condition - 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 it is the built-in memory that will play the main role.

True, there is still the 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.

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 worth saying about the memory card. Often manufacturers make the phone in such a way that it can accept SD cards of 200 GB - 1 TB.

The fact is that if the phone has 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 an amount of information.

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

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

Criterion No. 6. Camera

It’s 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 enlarge some part of the picture as much as possible, that is, use the zoom function.

If the enlarged part of the picture is blurry and unclear, this 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 phone and camera manufacturers are trying to attract people with the number of megapixels.

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

The size of the aperture or relative aperture also affects. The meaning of this value can be explained with an example.

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

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

In the same way, 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 apertures.

It becomes clear that the smaller this number, the larger the aperture; accordingly, the more light it can capture and the better quality the pictures will be.

Megapixels + aperture

It’s interesting that there’s a lot written on the Internet now that nothing at all depends on the number of megapixels and that only the aperture affects the quality of pictures.

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

Therefore, it is better to choose phones with a minimum “f/” value and a maximum number of megapixels.

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.

According to these parameters, cameras from Samsung perform very well. In general, this company has many of its own technologies, one of which concerns cameras.

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

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

And here is a photo of the same area taken on a Samsung Galaxy S6.

Agree that the photo taken on 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, focus on 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 (usually the first).

Criterion No. 7. Screen

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

• Diagonal.
• Permission.
• Pixel density.

Let's look at each of them in more detail.

Diagonal

This characteristic reflects the distance from one corner of the screen to the opposite one. The figure below clearly shows this distance.

The screen diagonal should be chosen depending on why the phone is needed:

• 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

Screen resolution is directly related to diagonal in the following ratio:

• for a diagonal of 3-4 inches, the resolution can be 480x800;
• for a 4-5 inch diagonal, 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, the clearer the image should be.

Typically, manufacturers try to make the number of pixels per inch corresponding to the screen resolution.

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

You need to look at the previous two parameters - diagonal and resolution. In addition, the following parameter is 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 see phones with the last two types of screens, but in the West they are very popular.

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

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

In particular, viewing angles will be much better.

This option means that you can look at the phone from almost a right angle 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, which use a lot of their own unique technologies, so Samsung with Super AMOLED is much better than any other phone with Super AMOLED.

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

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 a TRILUMINOS screen, the second is Samsung Galaxy Note 3 with Super AMOLED, then there is Sony Xperia Z1 with the same TRILUMINOS and the last one is Lg G2 with IPS.

It is clearly visible that Samsung looks better than the rest.

Criterion No. 8. Phone brand

As for which brand of phone to choose, the following points will help:

• If it is important to you that your 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 you'll have to pay about $150 for shipping. It turns out that the guarantee makes no sense.
  You can, of course, find a local craftsman, 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 performs well, but it costs more.
• If a good camera is important, then Samsung, Sony, Apple, Lg, HTC, Lumia and some Lenovo models.
• If ease of use is important, then all phones operate on the Android operating system.
• If operating time 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 Samsungs, but basically, all models work for at least 5 years.
• If you don’t want to spend a lot (“I want something inexpensive, but good”), 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 buy an iPhone only in cases where 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 break, to withstand falling into water and other emergency situations.

Of course, you can cover the phone with cases, protective films, and generally wrap it in film 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.

Finding a smartphone with a high degree of security is very simple - usually the characteristics say “IP...”, for example, “IP67”. This means the level of protection.

By the way, the most secure phones have a protection rating of IP67. Therefore, if you plan to drop your gadget often, it must have “IP67” on it.

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

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

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

This glass has a high degree of resistance to scratches and impacts.

With such glass you will not need any additional protection.

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

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

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

Tip #10: Choose a phone with Gorilla Glass protection, or buy additional glass along with the phone.

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

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

Results

If you want to hear an expert’s opinion on 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, 12 MP camera and 3000/3600 mAh and, most importantly, a curved display.
  In principle, the popularity of the phone will be due to its unusual display. But all other characteristics are pleasing. This pleasure costs about $900.

• Xiaomi Redmi Note 3 And Samsung Galaxy J7. The undoubted leaders of phones in the budget category (up to $300). Both have a diagonal of 5.5 inches and 16 GB of internal memory. Samsung has a 13 megapixel camera, but it takes better pictures than Xiaomi.
  Xiaomi has 2 GB of RAM, Samsung has 1.5 GB. In AnTuTu, the first one 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 version), 28 megapixel main camera, 4200 mAh and resistance to immersion in water - all in the best traditions of Sony. The cost is about 800 dollars.
