Xiaomi's upcoming Mi Mix series smartphone, allegedly dubbed the Mi Mix 2S, has been the subject of a number of leaks and reports lately. This implies that the Mi MIX 2S will feature a significant boost in performance and power efficiency over the 2017 flagship phones, which are powered by the Snapdragon 835 chipset. While Xiaomi hasn't confirmed the unveiling of Mi MIX 2S at or before MWC, its specifications have surfaced online which give us an idea of what to expect from this smartphone. The Mi 7 could be backed by a massive 4,480 battery, compared to a 3,350mAh one on the Mi 6. The rising Chinese tech giant did not indicate if the model was going to be called Mi7 or something else, but from the looks of things, we can pretty much say with confidence that the Mi7 is indeed going to be unveiled at MWC 2018 and with a lot of RAM that you could ever hope to see in a smartphone. The next-gen Mi Mix handset could also be the world's first smartphone to be powered by a 2.8GHz octa-core Snapdragon 845 processor. The storage in the image can be seen as 128GB but it is more than possible that we see a 256GB variant being released too. It also reveals that it will be featuring an under-display fingerprint scanner.
Further, the Xiaomi Mi 7 has been leaked to feature a tall 5.6-inch screen with FullHD+ resolution, and an 18:9 aspect ratio, keeping with the trends. While the firm has been making waves with its Mi MIX2 and Mi A1, there are reports that the firm will soon debut the Mi 7. In the camera department, the device sports 16MP + 16MP dual rear cameras and there is no information about the front-facing camera.
We advise you to take this design and specs with a pinch of salt as the authenticity of the leak is not guaranteed. The company already updated 40 devices, including some 5-year old Mi phones to MIUI 9, so it's impossible that the Mi 7 will run on older UI.
