mines takes 4 hours to charge. i think that usb cable is really slowing things down.
if you are doing it through the USB on the computer, you are right. It is more of a trickle charge because of the differences in the Amps (?) that USB puts out compared to plugging it in the wall. Mine goes from dead (10%) to full in about 3-4 hours plugged in the wall, 6+ on the USB.
I had issues with the Fascinate, but I chalk it up to me being new and the fassy being a bit of a dud. I have nothing like it with the Charge. Battery is good to me (and I am a heavy user) 4G has been rock solid, I havent missed a call or message.
Unfortunately some of this stuff is trial and error over several days. Do a fresh factory restore and charge the battery fully. Unplug and turn radios off and check in 3 hours. Should be at 70% at least. Turn on wifi, wait another 3. So on and so forth. Then load one app at a time and carefully watch it.
It's not something that can be fixed with widgets or technology. Hell, that battery widget might be killing it!
