When it's at 100% charge when I go to bed, it gets to about 80% when I wake up. This is weird because the first days I did this, it would be at 95% charge when I woke up about 8 hours later. I even have GPS, 4G, Wifi, and mobile data turned off. In the battery usage, it has a bunch of things that weren't even in use, such as certain apps, and display (which was off ovbiously). I have an app terminator, but after I force close all the apps that I never even opened in the first place, 5 seconds later they are automatically restarted. Wtf? What's going on here? Do I have to root the phone to solve these problems?
