I don't know about everyone else but the erratic performance of the battery to me maybe points to manufacturing defect. Today i charged overnight with the phone one, turned on while still plugged in, unhooked and used for about 35 mins of web browsing over wifi, one sms, one voice-mail. Went down to 89%. Put it back on the charger and took it off anywhere from one to ten mins after it had turned green, was doing some other stuff and when i went to make a call noticed it has still on 100% after an hour. It was idle the whole time so i decided to do some web browsing for the same amount of time as before over wifi, also did some sms and made a few calls. Over 3 hours later it reached 89%. It makes no sense. Yesterday I only got about 4 hours of use before i got the warning, and for about 20-30mins of that it was on the car charger, and i charged to 100% and pulled off right when it turned green that time. There must be something wrong with the batteries they sent out that makes them so inconsistent.
