Xiaomi hasn't done anything unusual with the Mi 4S - after all, the flagship understandably received more attention. The re-design works quite well though and the hexa-core chipset is a sensible choice considering the phone's standing in the pecking order. Its productivity should be comparable to a Snapdragon 650, power efficiency in favor of the 20nm Snapdragon 808. As usual with Xiaomi, the sealed battery and the shared SIM / MicroSD card slot shouldn't be unexpected. We hope the Mi 4s lives up to its legacy and, well, keep the surprises mostly pleasant. Let's see how the things turn out this time - our hardware tour starts right after the break.
