there are times i play angry birds for 20min or so… if battery for me was at 90%…it would prob drop to somewhere in mid to low 80’s
with pretty heavy use (txts, angry birds, browsing, network always on, blue tooth on at times during day), i can go a good 16 hours and the phone at that point is at 15%-20%
On a related note, I was previously running the Bugless Beast ROM on my Droid 1. For a while I’d been noticing shitty battery, slowness, and a few other bugs. Reverted back to stock + root yesterday and it is worlds better.
I play angry birds on the crapper for at least 20 minutes. If my battery drains 10% that’d be a lot. I’ve even driven to my fiancee’s house listening to a podcast via the browser and my battery really didn’t wear that much. As far as I can tell when I’m listening to that podcast the screen also stays on. I also use a Brightness Toggle Widget in order to lower my brightness lower than the stock power control widget
