This table provides a detailed comparison of those included in the review models of smartphones, and the full list is presented in the catalog of mobile phones.

 
Super AMOLED screen, water protection.

Junior representative A of the 2017 series. In terms of design, it is close to Samsung Galaxy S7 32 GB and unlike the "older" brothers A5 and A7, it has a screen size of 4.7" with a resolution of 1280x720 pixels.

The key feature of this device can be called a Super AMOLED display. Its main advantage is energy efficiency, all black pixels are turned off when displaying images, which allows a smartphone with a battery capacity of 2350 mAh, with average use, to work a day.

The case is made of glass and metal, assembled with high quality, and looks premium. From the point of view of ergonomics, the smartphone is made quite thoughtfully. For example, the speaker is located on the right side, above the lock button, respectively, it will not be possible to accidentally close it with your finger.

The processor of the Galaxy A3 2017 is an eight-core Samsung Exynos 7870, and the RAM is 2 GB. The smartphone was not created for demanding games. "Iron", taking into account the price, does not break performance records, but at the same time: premium case materials, dust and water protection according to the IP68 standard (withstands prolonged immersion in water) — all this allows it to be an excellent device for everyday use.

The operating system is Android 7.0 Nougat with the Grace UX graphical shell (TouchWiz reincarnation), which, due to overloading with unnecessary functionality, can sometimes slow down.

Apple iPhone SE is nothing but a reinvention of Apple iPhone 5S 16 GB . The smartphone, at the time of release, had flagship hardware from Apple iPhone 6S 32 GB , except for the front camera, but made in the design of the iPhone 5S. Just like the "five", the smartphone did not receive protection from water, which, although not critical, does not meet the standards of a "modern smartphone".

The smartphone is equipped with a 4-inch display, which is not enough in modern realities, but the matrix has a resolution of 1136x640 pixels. This ratio of diagonal and resolution allowed us to achieve an impressive pixel density per inch, namely 326 — the picture is dense and clear, individual pixels are not visible. The screen responds accurately to clicks — it is convenient to print, but consuming content that is often sharpened for large screens is not fun.

As a dialer with smart functions — it fits perfectly. From the point of view of memory equipment, the smartphone is available with 16, 32, 64 and 128 GB drives — everyone will choose something for themselves. The best option is 64 GB, given the lack of a memory card slot, this is enough to not feel a lack of memory and use it comfortably.

The battery life of the iPhone SE, given the volume of the battery (1642 mAh), is acceptable. For everyday use (screen activity up to 4 hours) the smartphone is able to work all day.

 
Xperia Home shell, fingerprint scanner in the lock button, water protection.
 
 
Placement of volume buttons.
 

Sony is one of those corporations that thinks about fans of compact devices. Sony Xperia Z5 Compact is the younger brother of Sony Xperia Z5 32 GB / 3 GB Price from £100.00. The flagship was once presented in 2015, but due to a competent combination of hardware and design, it is relevant to this day.

The smartphone is made of glass and metal, which is typical for Sony. The back side is made of frosted glass, which made it possible to significantly reduce its hardness. Protection from water and dust according to the IP68 standard provides immersion in water for up to an hour and to a depth of 1.5 m, and the "gloved" mode will allow you to use it comfortably in winter.

I would like to highlight the placement of the fingerprint scanner, it is located on the right side and is combined with the power/lock button — quite convenient, but at the same time the volume buttons are not located in the most successful way, and they are located on the right side under the lock button.

With a display diagonal of 4.6", the smartphone has a resolution of 1280x720 pixels and is "seasoned" with Sony proprietary technologies to improve the picture, such as X-Reality and Dynamic Contrast Enhancer. The processor is Qualcomm Snapdragon 810, which has proven itself as a stable and well-optimized chip, its only drawback is excessive heat dissipation.

A smartphone running Android 7.1.1 Nougat with a proprietary Xperia Home shell that looks stylish, works smoothly and stably.

Compact version of the flagship Sony Xperia XZ1 64 GB / 4 GB Price from £76.99 up to £179.99 , which, according to tradition, differs from the "eldest" only in diagonal. With a display diagonal of 4.6" (versus 5.2 for Xperia XZ1) with HD resolution.

The design concept called "Loop Surface" includes a body made of plastic, sloping edges on the sides, but as if the lower and upper ends are "cut off". In general, the smartphone looks stylish and concise, though without a hint of framelessness. The fingerprint scanner, traditionally for Sony, is located in the lock/power button on the right side.

The processor is Qualcomm Snapdragon 835, which in conjunction with a good optimization of Android 8.0 Oreo gives excellent final performance. The smartphone will cope with absolutely all modern games and applications, and thanks to the branded Xperia Home shell, it works smoothly and stably.

The main camera, taken from Xperia XZ1 and XZ Premium, boasts an advanced slow—motion shooting mode — 960 frames/sec at a resolution of 1280x720 pixels. In general, the smartphone takes photos at the level of the iPhone 7, and slow-motion shooting will be a nice bonus.

Autonomously, the smartphone is able to work for up to two days with average use, which with a battery capacity of 2700 mAh is an excellent indicator.

In terms of price/performance ratio, among the current iPhone models, the Apple iPhone 7 is an excellent choice.

It is available in a huge number of colours, from glossy Jet Black to bright and stylish Product RED, and the drive can be 32, 128 and 256 GB in volume. To date, the most optimal amount of memory is 64 GB, as this is the golden mean for comfortable everyday use. Unfortunately, the iPhone 7 is presented either with a 32 GB drive, which is not enough for comfortable use, or 128 GB, which in most cases will be an overpayment for extra memory.

The smartphone has water protection according to the IP67 standard, according to Apple, with a smartphone you can not be afraid to get under heavy rain, but experience shows that the smartphone perfectly tolerates short-term immersion in water.

The screen, with a diagonal of 4.7", has a resolution of 1334x750 pixels, and the processor is Apple A10 Fusion. To date, the smartphone works smoothly and stably, there are no complaints about performance. Of the obvious disadvantages, we can highlight the lack of a headphone jack, but there is an adapter included.

I would like to mention the vibration motor called "Taptic Engine", which generates high—quality vibration output — lovers of tactile sensations will appreciate it, and the display with the recognition of the pressing force allows you to interact with your smartphone in a slightly different way — a useful time-saving option.

From a battery with a capacity of only 1960 mAh, a smartphone with an average activity of use is able to work all day, but when active, it is discharged by lunch.
