The ROM I'm on is ParanoidAndroid 3.99-RC2 on an AT&T Galaxy S3. I've been having battery problems for awhile on this phone, but after upgrading to this, it has just gotten much worse. I take a look at BetterBatteryStats and it says my wifi is running all the time. I don't have wifi on most of the time, and I've reset the phone and it is still occurring.
