I need to know if I should exchange my iPhone. I know the battery issue has been discussed to death, but my return date ends tomorrow and I need some advice. I've had my phone for 13 days and have a gone through quite a few charge cycles. and I still have the same battery life as I did when I got the phone. It seemed today that the battery life is getting worse. After 10 min. Of phone calls and 45 min. Of safari on wifi my battery went down to 90% with about 1 hour usage and 2 hr standby. Right now stats are: 3hr 47 Min. Usage 11hr 29 min. Standby Battery is at 20% For what its worth its a 5 series. Nothing else is wrong with it except for the battery but I think this is a bit under par. Thoughts?
