I have had my s3 for about a week, got it from t mobile. The battery seems like its dying really fast. I have juice defender (balanced) on, power saving on, I turned off syncing, brightness is at 20-35%, Wifi is on at home, and I turned off background data for most of the apps I used. I am at 82% today with 8hr 50m on the battery. The cell standby says 49%. The screen is 26% but its only been on for 50 minutes. That was only for tweeting and looking at the news. Is this normal?
