I've had this phone for about a month and a half (or look at the day I joined this fourm). The model I have is MS323 and even before I putted Cyanogenmod12 (used to have stock), stock had horrible battery problems. After like 2 hours it goes down to like 50%. When I first got it, it holded up like a champ. 2 Hours was like 80%, now after a month it gets more worse. Also another problem is the battery heating up like it's melting and I need to stop using it and let it charge so it doesn't burn down or something. Has anyone else had problems?
