I was hoping to get some serious play time in yesterday, but I ended up working long and got home late, so i've had extremely light usage. About half hour playing transformers legends(which absolutely killed the battery in my Bionic), about half an hour playing dots, streamed a half hour video, had 3 or 4 phones calles and a bunch of texts and emails. My total screen on time is 2 hours 44 minutes. My time off the charger is 1 day, 6 hours, 24 minutes, 23second. My battery is at 31% I'd say that's still pretty damn good. Can't wait til the weekend when I can see what this thing is really made of.
