i have this problem almost for a month!
my Mate7-TL10 battery drain so much when the screen locked!
i tried everything, delete apps , optimise , delete google play services cache , greenify, battery calibration, reset factory.
and still there, i can't use my phone anymore. i charge it more than i use it!
when i use snapchat or instagram and twitter for 1-2 hours straight i just lose about 15-20% ( give or take ).
i feel like i lose more when the screen locked!.
every time i sleep and wake up i have to charge it again. if i'm lucky i have 5-7% left
i don't think it's battery life , because the problem just happend in one day.
i was sleeping and it's fully charged then boom , battery drain all day everyday!
here is couple of reports BetterBatteryStats generated. i don't know if it will help my problem
it's really frustrating, i can't use it outside.
if anyone could help me that would be epic and much appreciated.
ask for screenshots,try new stuff if that could help solve this problem
