Ok, I have a problem with battery drain. When I go to the battery history, 3. bar, "usage", is always present. And that cause battery drain about 1% per hour when phone is on standby. When I kill all apps with Clean master, 3. bar isn't present always anymore, just when I actually use phone.
Anyone had any problem like this? Can you reccomend me any battery monitor app that could solve this problem (find the problematic app)?
I'm fully stock, unrooted etc.
