Xiaomi Redmi 15 4G Review: specs and features, camera quality test, gaming benchmark, user opinions and photos

Xiaomi Redmi 15 4G - battery life and something else?

Just a couple of years ago, smartphone manufacturers could achieve commercial success for their products by giving them just one significant competitive advantage. However, today such a strategy is unlikely to work with a sophisticated audience. And it seems that the hero of today's review will still be deprived of the title of bestseller.

The appearance of the new product is not bad for the price segment, but nothing more. It is unlikely that the wide display frames by today's standards will be received positively, but with everything else, the device is in perfect order. The colors of the rear panels are beautiful, the photo module block is stylish, the side fingerprint scanner has not disappeared from the device. There is moisture protection, but not complete (IP64 standard). The 6.9-inch IPS screen has only one noticeable drawback - this is the brightness reserve. In 2025, 500 nits is not enough even for an IPS panel, because it is virtually impossible to work with it in direct sunlight. But there is a FullHD+ resolution that is not the worst for a diagonal, a decent refresh rate of 120 Hz, as well as relatively realistic color rendition. But there was not enough money for an oleophobic coating.

The technical characteristics include the Qualcomm Snapdragon 685 CPU, 6 GB / 8 GB of RAM and the Adreno 610 video core. The bundle is frankly disappointing in performance, using, for example, MediaTek Helio G100 would be preferable with a similar processor cost. Less than 300 thousand points in the AnTuTu test indicate that the fairly resource-intensive HyperOS shell based on Android will often greet the user with lags, and demanding games will lag even with minimal graphics settings. But with a 7000 mAh battery, the battery life will be increased to 2-3 days. Charging is not very fast, but with 33W you won’t have to stay near the outlet for long. As for the permanent memory, its volume can be 128/256 GB with a slot for MicroSD cards.

The cameras have basic photo capabilities. The 2-megapixel portrait sensor can be ignored, and the main 50-megapixel sensor without optical stabilization does not always cope even with daytime shooting. The dynamics of objects or deterioration of lighting will turn a photo or video into an abundance of noise, blurs and other artifacts. There is no stereo sound, listening to music is unlikely to cause a lot of pleasure. The availability of NFC contactless payments should be clarified before purchase, because they are not available in all regional versions. But there is a place for an IR port everywhere. Thus, we have a slightly outdated gadget in front of us, which has many alternatives.
