My iPhone 3GS is only a couple weeks old and the battery has started draining really fast. Today, it's only been off the charger for about 2 hours and was only used once to make a call and to check facebook. 3 minutes of actual use, tops. It's already down to about 50% battery life. I think it's a software thing. The same thing happened yesterday. After a few hours of being off the wall charger, it was down to about 30%. Then, I plugged it into the computer for about a minute and it was back to nearly 100% and was fine for the rest of the day. I tried restarting the phone today to see if that somehow jostled things into working. It didn't. I don't mind isolated issues, but this is starting to seem like a chronic problem. Anyone know what's going on?
