I'm still under warranty for about 3 more weeks. I've noticed it seemed a bit off the last few weeks but tonight sealed the deal for me. I had it charged to about 85-90 percent before I left my house at 5:30 p.m. I got home at 9 p.m. and the phone was dead. 3 1/2 hours for a nearly full battery and I had 2 texts and about 5 minutes of data usage during that time. My question is can I take it to AT&T and have them replace it there, or am I going to need to fill out the online service request and send it in to Apple? Going to the Apple store is out of the question for me, the nearest one is about 2 hours away. Thanks for any help you can provide.
