I've only had my G1 for less than a week, so I'm constantly screwing with it... so my battery discharges quickly. I can attach it to my PC at work to charge up, but I'd like more out of it. I'm thinking of getting an extended life battery. I've found one so far at ********* Has anyone else used extra batteries? How about the 1600mAh one from fommy? And new to report about it?
