Technical specifications and hardware platform

The heart of the Xiaomi Redmi S2 was Qualcomm’s Snapdragon 625 processor. At the time of its release in 2018, the chip was already considered a proven workhorse, although it was not a flagship. It was made on a 14-nanometer process technology, which provided a great balance between performance and power consumption.

RAM depending on the modification was 3 or 4 GB of the type LPDDR3. For the budget segment of the time, this was the standard, but today 3 GB can cause difficulties when working with "heavy" applications. Built-in storage of eMMC 5.1 32 or 64 GB in modern realities seems small, but the presence of a slot for microSD cards partially solved this problem.

The screen of the device has a diagonal of 5.99 inches and HD+ resolution (1440x720 pixels). Matrix type IPS provides good viewing angles, but the pixel density (282 ppi) is no longer enough.

It is up to modern Full HD+ standards, but for the budget phone of 2018, this matrix was quite justified in terms of cost.

The cooling system deserves special attention, because the case is metal, the heat sink is implemented through the frame, in hot weather or under prolonged load, the Redmi S2 could significantly heat up, which led to trotting, a typical feature of many smartphones of the period.

Camera: the model's main trump card

The Redmi S2 was built with a front-facing camera, with a 16MP Sony IMX376 sensor and an f/2.0 aperture. For 2018, it was a standout for the budget segment. The presence of a front-facing flash and Beautify AI mode made it a hit among selfie enthusiasts.

The main camera, with a 12MP module (Sony IMX486) sensor and an f/2.2 aperture, was a supportive camera that could take good pictures in good light, but at night or indoors quality dropped dramatically, and the lack of optical stabilization (OIS) was compensated by software algorithms, which, however, often “washed” details.

Video is limited to 1080p at 30 frames per second, and video stabilization is electronic and mediocre. For blogging or dynamic scenes, this phone is no longer suitable these days, but it still has enough capabilities for document capture or simple videos on social networks.

The front panel features a speaker, sensors and a front camera, and the "MI" logo, not the "Redmi" logo, which was the hallmark of the S/Y series of the period, is the bottom, and the navigation buttons in the newer versions of MIUI have been replaced with gesture controls, which has visually increased the usable screen area.
