How to choose a smartphone?

In the era of the active development of mobile technology in store windows you can find a huge number of smartphones with different prices and from different brands. How not to make a mistake when choosing?

Buying any equipment is not an easy task. Indeed, in the event of an error, you will find yourself in a situation where the device will have to be used for a long time, and there will not be any pleasure from it - the process will be frankly annoying. This is especially true for smartphones. Unlike other equipment with them, most modern people spend all day. Therefore, before you go to the salon, you should go through a short “educational program” and get acquainted with the main criteria for choosing a smartphone.


operating system

The operating system (OS) is one of the key factors when choosing. It is for her that developers write applications, it determines the usability and sets the interface with which to deal every day. At the time of writing (October 2019), choosing an OS on a smartphone is essentially not a choice. There are only two actual operating systems, another survives the last days.

  1. Android This operating system is used by almost all electronics manufacturers from the market leaders Samsung and Xiaomi to little-known Chinese. Android has many positive aspects: it is the easiest to learn, offers the richest applications and games store (Play Market), allows you to maximize the interface for yourself, has simple synchronization with a PC. Among the minuses is vulnerability. There are a huge number of viruses on Android, so it is recommended that you immediately install a high-quality antivirus.
  2. iOS is an operating system that runs exclusively on Apple gadgets: iPhone and iPad. iOS guarantees not only fast and stable operation of applications, but also protection against viruses. However, novice users may experience difficulties: data transfer occurs only through the iTunes computer program, so to download your favorite song, you will have to deal with this software as well. In addition, iOS is a closed system, there are fewer applications (this does not mean that there is a lack of choice) and the most interesting of them are distributed only for a fee.
  3. Windows is the brainchild of Microsoft . This operating system has become obsolete and by the end of 2019 its support will be discontinued, after which it will work for another year, but without updates. You can still find devices with this OS on sale, but buying them is a waste of money, because in a year the device will turn into a useless “brick”.

There are other operating systems, but their distribution is so insignificant that to buy a smartphone with one of them is hard, even by chance, and completely impossible.


It is important to choose a phone according to performance parameters, otherwise there is a risk that the gadget simply will not be able to “pull” the user's favorite games, it will hang and bask. To a greater extent, it depends on the chipset and random access memory (RAM). The first is selected by manufacturer, number of cores and frequency, memory is just by volume.

Correctly pay attention to these parameters:

  1. Manufacturer - Qualcomm processors are considered the most relevant. As a rule, the presence of a chipset from this brand already speaks of decent performance. Following is the brand MediaTek, it feels great in the budget and cheap segment. Huawei uses its own HiSilicon processors - many of them show decent results. The Korean brand Samsung works similarly. The latter sometimes sell their chipsets to competitors. In a budget environment, you can also find Spreadtrum. This is a relatively young brand, which connoisseurs prefer to bypass for now.
  2. The number of cores . The more of them, the easier it is for a smartphone to work in multitasking mode. Today, chipsets with 4, 8 and even 10 cores are common. As a rule, 4 cores - the destiny of the budget segment, 8 cores - medium and higher, 10 cores - a rare occurrence in the middle segment.
  3. The clock frequency is responsible for the number of operations that a smartphone can perform in a minute. A processor with a high frequency will allow you to run "heavy" applications. The average value is from 1500 to 2000 MHz. In top models, it can reach 2800 MHz.
  4. Random access memory (RAM) affects the speed of current tasks. Selecting less than 3 GB is strongly discouraged.

Inner memory

The internal memory does not globally affect the speed of the mobile phone, but it depends on this parameter whether the user can copy to the device all multimedia files (video, photos, music) that are dear to him.

When choosing a smartphone, you need to pay attention not only to the amount of internal memory, which should be at least 32 GB, but also to the presence of a slot for a flash card. It allows you to add volume. Modern devices often do not have such a slot or make it combined - you have to choose: a second SIM or a memory card . However, it’s quite possible to find a device that has a separate microSD slot . If you are not a fan of cloud storage , and also do not clean the memory, then you should look for just such a device.


Choosing a camera is the hardest task. Even 5 years ago, the whole choice came down to estimating the number of megapixels. Today, this approach will be extremely illogical. It’s best to read reviews about the camera, try to try it in different conditions, at least in the store, see photos taken on this device, and if it belongs to the category of flagships , then look at the DxOMark service. This is a professional approach to assessing camera capabilities. Every month, the results of the cameras (and not only on smartphones) are laid out here, the credibility of which is difficult to call into question, which means that when choosing you can take into account the assessment of the gadget on DxOMark.

We do not talk in detail about cameras, because this is a serious issue that requires a separate text. Firstly, modern phones use multi-module cameras, each of them has its own characteristics and is designed to perform different tasks. Secondly, there are many parameters: aperture size, photosensitivity, shutter speed, type of stabilization, etc.

As practice shows, even knowledge of terms does not always help to make the right choice. Therefore, it is easier to read the reviews of professionals or trust friends who already use the device and can talk about their own experience using the camera or show pictures.


Many people buy a smartphone not as an expensive toy, but to help with work. In this case, it is especially important that he can "live" for a long time and not "sit down" at the most inopportune time. The battery life should not be judged solely by the battery capacity.

Battery capacity is only considered in conjunction with other parameters. Smartphones with high performance or the ability to use two SIMs require a more powerful battery. Similarly, the size of the screen and its type affects the flow rate. In the budget segment, it is better to choose a device with a battery of 2500 mAh. On average and above from 4000 mAh. But this does not mean that a volume of less than 4000 mAh is bad. Software optimization is a great thing. Some manufacturers manage to configure the device so that even with a modest battery, it gives impressive values ​​for working without charging.

It is important to clarify when buying whether there is a fast charge in the phone. Thanks to it, the battery can be charged for several hours of use for a short period of time, which is very convenient.

Wireless interfaces

In the modern world, a smartphone is used not only for calls, but for some users this is generally a secondary task. In order for the device to meet the requirements of the present, it must have support for certain modules and wireless standards.

  1. LTE (4G) - provides high-speed boarding through a mobile network. At the time of writing (October 2019), there are already 5G networks and smartphones with their support, but for Russia they are not relevant, since we do not have to wait for their launch soon. But if you buy a device with an eye to the future or plan to visit abroad often, then the presence of 5G may come in handy.
  2. Wi-Fi - there are different generations (standards) of work in this wireless network. The most relevant in smartphones is Wi-Fi 802.11 ac. In fact, it provides the highest connection speed, but is not common. Many users are not aware of the existence of generations, and manufacturers use it and actively save. The previous type, more common - Wi-Fi 802.11n. If it is not there, then such a device for purchase is better not to consider.
  3. GPS / Glonass - satellite communication modules. In modern devices, they are in 100% of cases.
  4. Bluetooth - a module required to connect a headset to a smartphone. It is in any modern smartphone, but it can differ by generation. Actual - 4.2 and higher.
  5. NFC - a module for synchronizing devices. This is not known to many buyers, since the main task that he solves in the understanding of users is contactless payment. Is it possible to call NFC necessary - hardly, but if it is available, living becomes definitely a little more comfortable. When buying a device from foreign sites, you should clarify the performance of NFC. For some smartphones, it works only in the domestic market.


In this text, we talked about the criteria that are really important for a smartphone. We did not focus on the screen diagonal, resolution, body materials and other similar things. They undoubtedly matter, but even the most beautiful mobile phone with a super cool display with a weak chipset or a small battery will cause you only disappointment.

When deciding which gadget to choose, refuse to participate in the "arms race." Buy the device that is 100% suitable for you according to its characteristics, and not just crammed with features and innovations that are useless to you. Only this approach will give you a pleasant experience in use and help save money.
