I have a brand new g3 (t mobile) and have been fighting terrible battery life since day 1. Usually I find my phone hot and eating battery rapidly. 20% down in about 2 hours. I have shutoff the gesture recognition, hello google, location services (network only mode when I need them), no Skype, no Facebook. I've had two days of great battery life. Seems that even having amazon kindle or pandora installed hurts so they're removed but I'm still suffering terrible battery life. I actually don't use my phone other than to try and find out why the (inappropriate language edited by Moderator) battery is being burned through so quickly. And the advice in some of the forums (turn off your phone, shutoff data usage, keep a spare battery, etc) is some of the worst non-technical advice I've seen. For example, hot phone = lots of battery usage. Battery usage = heat. The (inappropriate language edited by Moderator)** is hot because the processors are doing SOMETHING. What it's doing is anybody's guess tho right?
