Anyone else have this problem? I have a stock, non rooted Thunderbolt, no extended battery either (waiting to see what GB does for the phone). Anyways, I have it plugged each night before I go to bed and when I unplug it, the battery automatically drops 5-7% when i unplug it when I wake up. If I put it on 4G, it usually drop 7-9%, 3G usually drops 4-7%. What the heck is going on here??!
