My S3 that I got used a few days ago has a weird battery drain thing. It will drain just sitting in my pocket, with nothing on besides cell signal and a strong WiFi connection. It will drain kinda quick when just listening to music through headphones, if I do it for like 45 minutes, it will go down about 10%. Right now, I'm listening to music from it without headphones plugged in, it's just sitting on my stand I have playing music through the speakers. It's been doing that for the past 30 minutes or so. The battery has only dropped like 3% at most. When I play Tetris, it will drain like 6% or so in like 15-20 minutes. Is there a fix to it? I was thinking maybe a soft reset, but I have no idea how to do that on the thing. Attached is a screenshot of the battery monitor thing. The reason the graph goes up in a couple places is because I was charging it while in the car and at school from my laptop.
