Hmm just had a weird problem just now. I was using my extended battery but decided to switch to my slimmer regular battery. For some reason when I plugged the charger in the light lit up like it was ready to start charging but it wasn't charging. The connection is fine because it lights up (the screen not the orange light) and if i plug it into the computer I can still sync data fine. I was baffled so I switched back to my extended battery and it charges fine, could this be a battery issue?
