    Are you rooted? I'm stock and I drop to 99% after a few minutes of being unplugged.

    Give this a shot. I was having the opposite problem...my battery would show 10% and I would power cycle and magically have 20-30%.

    Good and keep us posted on if this works or not

    Mine is going from 100% to 90 % in about 15 minutes. I am going to calibrate the battery to see if that solves the problem. If it doesn't, then I will be making a trip to the AT&T store to have them swap it out.

    This is normal for most phones across the board first ten % drops quickly calibrating won't help. I wouldn't worry about it

    You're not the only one: http://forums.androidcentral.com/gal...or-issues.html

    Seems to be related to using a non-samsung charger, or maybe just chargers designed for Apple products. Mine does it every time with my u-socket, but not with the Samsung wall-wart or HP TouchPad charger.

    I think it has to do with the charger. Are you using a different charger other than the Samsung one that came with the phone. I had this problem for a while and was using a different plug in the outlet. Once I switched back to the Samsung charger that came with the phone the problem stopped. You should try this.

    Just to update, 3 weeks in I went back and they exchanged the device for me. Same thing happened. So 2 days before my 30 days was up I just returned it. At&t rep told me to wait for an update, except I wasnt gonna wait for an update that may not fix the issue. Really liked the phone, but the battery bug & some email issue I was having was a deal breaker.
