I don't know why I should complain. I turned on my G3 about 9AM and here it is 11PM with 70% left. Screen was at 30%, I downloaded a full movie, made a few calls. I'm not a phone junkie and that's a good thing with this phone. Guess I should be satisfied. What you say about the screen and GPS is what the GSAM battery monitor is telling me about the most battery drain so I should mention I also turned off my GPS for most of the day. I also use the Battery Doctor app. Wow...70% though, really.
I still want a bigger battery though. I do not want to make any sacrifices for longer life and I want more than a days worth of heavy use, like I had with my GS3 with the bigger battery.
