Just waked up and saw my phone shut down. So as you may have seen in the title, the battery was completely drain. It's the second time I have this problem in 6 months. First time I've got this problem I made a factory reset and it was solved till now and I also thought it was because I installed a new app. But this time I didn't install anything in the past 3 days. So if someone had the same problem and can give me some help, it would be gladly appreciated .
Sorry for my English.
PS. I'm on stock ROM rooted.
