My battery life has been awful for the past few months (even before updating to 5.0.1). I work with a guy who also has a G3 and he is shocked at the difference in our battery lives. Right now I'm getting around 3-4 hours of screen on time, and MAYBE 10 hours low usage. Since I know it should be better I've decided to replace. I'm not interested in the 6000 or 9000 mAh batteries since it would make the phone super thick. So I'm wondering; have any of you replaced your battery with another 3000 mAh bettery? If so, which one and would you say it's as good as the original one?
