I know that my iPad gets 10+ hours of daily usage. However, I noticed two things in the settings grid and wondering if you are experiencing the same thing. 1. The brightness option is right in the middle, meaning not at full brightness. If I max it out will I lose battery time, or is 10+ hours on max screen brightness? The brighter the better! 2. The auto-brightness option is on, but it does not seem to actually work. I have gone into dark rooms, light rooms etc, and the screen never seems to get any brighter or darker. If I was on any one of my macbooks, the light would go crazy. Isn't that the point of the ambient light sensor? I'm not sure the light sensor is actually working. What are you guys getting?
