I understand the new game engine might use more power, but is this battery level good for the time i was using it? First: I didn't charge before i left, but it did show full on the meter. I understand full isn't 100%, it could be 90. Firmware: 2.0 Battery level when home: Less than 1/2 but over 20% (green) Time used - 1:30-4:40 straight, maybe 10 mins not in use Games played: *Sudoku - Majority of the time *Mahjong - 2 games *Monkeyball - 20-30 mins Music: Yes, The whole time except for monkeyball, Vol. level maybe 50% cuz of car. Brightness: 1cm lower than 1/2 All this being said, is 3 hours of all that (with straight usage) and battery level a tad less than 50% good? or does 2.0 just suck up power.
