how long does it normally take for a completely dead Eris to charge back up via a/c adapter? got this Eris monday this wk, it charged fully in abt 3hrs the fist time. the phone has to be charged daily and every day, the indicator light stays on showing its charging and its been over 4hrs. on Tue, accidentally unplugged from wall. plugged back in, the indicator light shows still charging for abt 30 secs then the fully charge (green) light comes on. every day, i have noticed this...the light stays (orange, meaning its charging) but once i unplug from wall, it turns green after a few secs. sounds light a defective phone?
