Battery Life Screenshot
I see that you found your issue, glad to hear it's back to normal now. Too add to the conversation, I just picked up a Galaxy S3 a few weeks ago, not seeing the battery life issues that most seem to complain about. The above screen shot is from a relatively light use day, but I still typically only have to charge my phone for a few hours at work each night. I normally plug it in via USB around this time of night, take it off the charger around 10pm, and I'm good to go until the next evening at work. Sometimes I will plug it in at home or in the car for a little while if I need a boost, but never more than a couple of days / week.
