I had the brightness set at exactly half, which is what I usually use. It seems plenty bright enough for me. The audio was 5 steps down from max. I didn't want to hear that Superman cartoon for several hours. I wouldn't think that the volume would have nearly as much impact on battery life as brightness.

I wasn't necessarily going for maxed out settings, as I wanted to see how long it would run with more typical settings.

Oh yeah, WiFi/BT off. Normal Flash boot.
