As soon as I unplug my Incredible 2 from a 100% charge, it drops to 96% in a few seconds. That's with and without my extended battery. Not life threatening but annoying haha. -Hunter Harris
Don't worry, its supposed to happen. Basically, if it were to really be 100% full it would be damaging to the lithium ion battery. Instead of saying battery full at say 96%, it says 100% to avoid making people angry haha
