BPMAs i have Stated before, its software causing drain to you guys and i Suggest factory reset ,
Gonna add to this thread (because we don't need 50 different threads for the same issue; it won't get it fixed any faster), but there certainly seems to be some sort of battery drain since the last few updates. I don't think it's been since the first Android 11 update, but I may be wrong.
I'm on the latest update (.201) and this is what I've experienced:
I fully charged my phone before going to bed, at around 9:37 pm.
When I had woken up this morning at around 4:16 am, the battery had dropped to 75%!
So, with 6 hours and 41 minutes of idle (and only 4 minutes of screen time), I lost a quarter of its charge!
I know that Li-ion batteries degrade over time, but I think this excessive even when considering that. I couldn't give a hard number, but I'm fairly certain that I used to only lose about 5-10% charge overnight.
I know the Android 12 beta will be starting soon (assuming it hasn't already), so there isn't much of a point fixing this with A11, but I do hope this is seriously looked into with A12.
