no, but something is not right with your iphone. Try to update or restore the firmware! Btw if you have google exchange set ul I would recommend removing it cuz contacts always fetch for no reason and loose battery life.

Perhaps because with t-mobile the iPhone is constantly searching for 3G but can never get any?

bad signal can affect battery.

If it stays at 100% for a couple few hours then starts dropping battery signal, then it sounds like the battery % is not reading out correctly.

Try draining your battery until it shuts off, then plug in and charge to 100% and leave it charging for another couple hours after it's full. Some say this will 'calibrate' your battery read-out. Not sure if it really works but you can try.

And btw, if your battery stays at 100% for 3 hours, then drains 1% every 2 minutes, thats still over 6 hours of battery life with the screen on. Which is not great, but if the screen is at full brightness and you are running apps or browsing/transferring data over 3g.... not terrible depending on what you are doing with it.

Have you tried to see how long it actually takes to drop to 0%?
