Just got the D.INC.2, and really like it. Very happy I passed on the fruit company offering
First couple charges had a lot of standby time & less use (I let the phone drain overnight) - really good "up" time, around the 20 hour mark.
Today was a good test of heavy use, lots of angry birds, amazon music locker, talking on the phone, went running using map my run with GPS for an hour, ect. Heavy use. Still got 13 hours.
In both cases, app killer was used, 30-40% brightness, and when i was not using services, I turned them off i.e. datasync. Yay widgets.
I'm really happy. All I need is my otterbox to show up & i'll be all set. I figure after the novelty wears off and i stop compulsively playing with it, I'll be able to get through a full day no problem.
