Where do you think you would be on your SGS2 at this point?
very close to if not fully drained. i couldn't leave my SGS2 on full screen brightness and expect to have enough juice to make it through the day.
one of the big mysteries about the N4 from all the reviews was the mixed battery reports. not sure what was going on there with that, but i feel very, very happy with battery life compared to my SGS2. i think i could really push this thing quite a bit further and definitely make it all the way through a long day.
