How to Choose the Right Phone: Top Criteria to Look at
Despite the external similarity, modern smartphones differ in technical characteristics and additional features, which affects usability.
Here are the parameters you should pay attention to when choosing a new gadget.
The diagonal and resolution of the screen affect not only its appearance but also ergonomics. Communicating on WhatsApp, working with Google Docs, playing at the best casino with no risks, and watching YouTube is more convenient on a larger screen. There are fewer models with a diagonal of up to 5 inches on sale.
The most common smartphones are with a screen of 5.5 to 6.4 inches. Models with better characteristics often have a diagonal of 6.5 inches. At the same time, most modern phones have frameless screens.
The resolution determines the clarity of the picture on the screen. The most common are:
- HD+ (in most budget models) – 1440×720 pixels.
- Full HD+ (in mid-range and premium smartphones) – 2160×1080 pixels.
- QHD+ and 4K (in some premium models) – 2880×1440 and 3820×2160 pixels, respectively.
At first glance, there is not much difference in the image, but it’s better to choose a model with Full HD+. A picture only in HD today looks “washed out”, and the difference between Full HD+ and QHD+/4K isn’t as big as manufacturers claim.

The quality of the picture on the display depends on the type of matrix used. Today you can find on-sale models with matrices made by IPS, TN, and AMOLED technology.
IPS matrix is characterized by high-quality colors, wide viewing angles, fast response time, reasonable price, and long service life. Optimal for working with photos and surfing the Internet.
However, more manufacturers are abandoning IPS in favor of newer and more advanced technologies. But IPS smartphones are still easy to find among budget and mid-priced models.
TN technology is the predecessor of IPS. The main advantages are cheapness, low power consumption, excellent brightness, and speed of response.
The main disadvantages are faint colors, low contrast, small viewing angles. In addition, displays with a TN-matrix over time often have dead pixels. If possible, it is better to refrain from buying a smartphone with this type of matrix.
AMOLED is an industry-standard and a reasonable compromise between price and quality. The essence of the technology lies in organic diodes, thanks to which AMOLED displays render a bright and contrasting picture at relatively low power consumption.
However, AMOLED has disadvantages. These are high price, noticeable flickering at low brightness (some budget models), backlighting in direct sunlight, and inaccurate color rendering. However, there are new modifications of AMOLED (Super AMOLED, Super AMOLED+, Dynamic AMOLED), where these drawbacks were eliminated.
The speed of your smartphone depends on the amount of its RAM. The more of it, the lower the probability that the operating system and apps will slow down.
However, you shouldn’t be guided by the amount of RAM. Manufacturers select the optimal values depending on other components of a particular model: CPU, graphics chip, camera, etc.
Built-in memory is required for data storage and installation of various applications. It can be small in size, but when there is a micro SD slot, increasing the storage capacity to 256 GB and above, you can buy such a gadget.
Modern smartphones are more often produced with several cameras. For example, the presence of a front camera allows you to take selfies and make video calls. But the main camera is responsible for the ability to take photos and shoot video.
It’s believed that the optical image stabilization system (OIS) is better than digital. It makes pictures clearer and smoother. For the first time, such blocks with lenses in smartphones appeared in 2012 and only in more expensive models, today the optical system is also available in the budget segment.
Each camera is evaluated primarily by a single matrix resolution. Megapixels is the main parameter for photos, the more this figure, the better photos will be.
The camera in modern models isn’t a separate element, but a bundle with the processor. Choose the phone in which the processor supports AI algorithms and you get the automatic detection of scenes and adjust the optics best for work.
There will be no lag due to the NPU module of the processor. A processor with this kind of stuffing has learned to solve problems almost instantly. Want a good camera? Choose a processor with high performance.
The more modules, the more photo opportunities and shooting closer to professional. Usually, the camera has at least 2 modules, but more and more often release smartphones with 3-5 modules to the camera. Let’s analyze them in more detail:
- A Wide-angle is a universal module. On it shoot portraits, take pictures at night, including when shooting smooth video. The most popular value of focal length is 24-27 mm. This distance allows the camera to capture more details with minimal distortion.
- Ultra wide-angle also serves to expand the lateral boundaries of the picture, allowing you to fit more objects into the frame. Such a module has a focal length of less than 21 mm.
- Telephoto is a module for zoom and portraits with double optical magnification and a focal length of more than 50 mm. The main purpose of this module is to zoom in on distant objects.
- Time-Of-Flight or 3D Lens is for blurring the background and creating a 3D picture effect.
- Macromodule is needed to take close pictures of small things. Without this module, it’s difficult to photograph different bugs, flowers, coins, other little things “full-size”. Due to the high aperture ratio and the long focal length the subject is even more emphasized in the photo on a very blurry background.
Experts are convinced that the modules in the cameras will become even more perfect, and innovations that are currently available only for flagships will appear in the budget versions.
The battery of 2000-3000 mAh is a compromise solution when the smartphone is used in moderate mode. In this case, it should be enough for at least 12 hours. If you use the smartphone actively, choose a more energy-consuming battery from 4000-6000 mAh.

Modern smartphones have a lot of additional features. Today you can buy a gadget for playing games, for watching cartoons by children, for distance learning, for an active lifestyle, and for maintaining your health.
There are a lot of additional features in smartphones. So before you buy a gadget, study its features to understand what is useful and what is not. Do not overpay for useless features, and choose only what you need.
