Hello, I am new here, so excuse me if the thread is in the wrong forum. I got a problem with my battery, when I was on iOS 10.3.2 the battery goes down by 40% when I go to sleep, now when I updated to iOS 10.3.3 beta 3, it is the same for the night, I charge it up to 80%, and when I wake up it was 42%, now I charged my phone (11:50 was on 80%) and I remove it from the laptop (the last time I charge it in my laptop to see if there is any difference, but no), and yes I use 3rd party wall adapter, but original cable (its second hand 5s). I restore it when I was on iOS 10.3.2 but there is again no difference. The charger is some Chinese AC adaptor. P.S. I stop the Push Mail, background app refresh, most of the notifications, location services and etc. Low Power Mode feels like it drains battery even faster.
