On what characteristics to look for when choosing a new smartphone

1. Modem and antenna
Of course with any smartphone you can make calls and surf the Internet, but not all of them cope with this equally well. For the quality of the wireless modem and is responsible, given the introduction of 5G, it is one of the characteristics, which should pay particular attention.
Modem affect the maximum data rate, with both mobile and on Wi-Fi. His specifications define the ability to work in certain networks in other countries and support for two simkarty. In addition, new modules are more energy efficient, which means less consumption of battery power.
No less important is the number of antennas. The more, the higher speed and stronger the signal. Typically, two or four antennas. For example, 4 × 4 MIMO (iPhone XS and XS Max) Involves four simultaneous data flow, while the 2 × 2 MIMO (iPhone XR) - only two.
And despite the fact that all smartphones use the same new Intel XMM 7560 modem due to fewer antennas iPhone XR loses half of data rate. This is especially noticeable in low-level signal at one or two levels.
Unfortunately, due compare modems from different manufacturers is difficult to insufficient information. But still try to clarify their specifications for devices, which look for.
Wait for the test to find out the number of antennas that are supported frequency bands and the number of sim-cards. After all, these differences will actually affect the routine use.
2. Degree of protection IPX
The level of protection phone or any other gadget for IPX standard indicates how they are protected from moisture and dust. Classification penetration levels are set and regulated by the International Electrotechnical Commission.
The first digit after the IP denotes the degree of protection devices against solid particles (dust): 0 - no protection, 6 - completely dustproof. The second number indicates the resistance to penetration of liquids (water): 0 - no protection, 8 - prolonged immersion in water. So, IP68 means complete protection against dust and moisture.
but waterproof from different manufacturers is treated differently and eight in IPX8 does not always mean the same degree of protection. Therefore, we must look to the depth data and the immersion time in the fluid specified in the specific characteristics of smartphones, and compare them exactly.
3. charging rate
For anyone who charges a smartphone once daily in the evening, this parameter is not very important. For those who are constantly moving throughout the day and has a limited amount of time, it becomes crucial.
charging speed, especially wireless, depends not only on the smartphone, but also on the power adapter. To work successfully support fast charging standard has to be in both devices. All manufacturers use different technologies, but it is possible to focus on the power adapter and charging time.
As a rule, in the specifications of the smartphone indicates charging time to a certain level, as well as the complete power supply adapter. It is indicated in watts (W, W) and is the product of voltage (B, V) and amperage (A).
For example, if the output voltage of the adapter 5, and the current 2 A, the capacity of 10 watts. If the voltage is 9 V, and a current of 1.67 A - power is 15 watts. Of course, the higher the power, the faster there is a charge.
4. neural processor
In the past year, manufacturers have started to equip smartphones AI systems, whose work is based on the neural processor. By analogy with the graphics chip responsible for handling the graphics, they are designed for computing, employs machine learning.
Neural processors allow to recognize objects in the photo, automatically adjust the parameters of shooting and sort images in the gallery on various parameters. Other examples of AI use in smartphones - a voice recognition and data processing applications in augmented reality.
All high-end gadgets have processors in one way or another have AI. For example, Apple is Neural Engine chips in A11 and A12 Bionic. Compare AI engines from different manufacturers is difficult, but the fact remains that a new flagship at the expense of data without unloading in the cloud are much faster.
5. Support for HDR
HDR technology provides a wide range of colors on the screen, making the image more saturated, more volume and more importantly, are detailed in the lightest and darkest areas of the frame. But in order to enjoy it, you need a special content and support of an HDR smartphone.
Now there are multiple embodiments of the technology. The most popular, mainly because of its openness, is HDR10. More advanced Dolby Vision require licensing, so the less common. Although superior HDR10 on the number of colors and contrast.
Thus, in the Samsung Galaxy Note 9 HDR10 used, and supports both iPhone XS HDR10 and Dolby Vision. Everything is complicated by the fact that not all applications support working with HDR HDR-with any smartphone. However, with the current models are likely to be no problems.
