TO ALL WITH BATTERY COVERS NOT CLOSING RIGHT: i've spent ALOT of money and time on this subject......i even broke out a micrometer/calipers to support my theory..... the problem is that even the best batteries SWELL just a smidge when charging and never fully return to original dimensions....droid has so cleverly utilized every square friggin' inch, there's no room for a hair!...swelling is more dramatic with a wall charger, and less so with a USB and computer.....a trickle charge is better with USB, i've found...less swelling and longer user times.....do your own research if you don't believe me!
