It has a 720p screen and 4100 mAh battery. Yet it's battery endurance of 80 hours shows a very poor use of it's resources. And it's not just the standby scores, even the individual scores aren't all that impressive considering the specs.
Kharma, 05 Jul 2017 how long will it take to fully charge the battery?? About 2 hours +/- 15 min depending on remaining charge
Beta rom on 7.1 is already out
Xiaomi phones note 1, redmi 2, all sucks. Its wifi feature was dead before the EOL of the phones and thus cannot connect to wifi, so not able to access internet. So I planned to apply a hammer onto the screens and dump them into the bin. full stop.
I have owned and used both the Galaxy S7 Edge (rated 92 hours in battery-test) and Xiaomi Mi Max (rated 108 hours), and my current phone Xiaomi Redmi 4X (a stopgap-solution until Xiaomi Mi Mix 2 arrives). As far as batterylife goes; the Redmi 4X is even better then Mi Max, and definitely better then Galaxy S7 Edge. This is my personal impression based on experience - although subjective. I get about 9-10,5 hours of SOT (Screen On Time) within one single charge-cycle - with about 10-15% left to go.
I always trusted GSMArenas battery-tests, but this time? No. Something must be wrong with either that particular phone, or that particular testing-procedure.
