Adjust screen brightness
Normally, the iPad's ambient-light sensor adjusts the screen brightness
automatically according to its surroundings. If you'd like to dim the light
or punch it up manually, you can do so in two places:
■ Go to Settings > Brightness & Wallpaper and drag the slider left
(darker) or right (brighter). To always adjust manually, turn off the
Auto-Brightness switch.
■ Double-press the Home button to bring up the recents list, swipe right,
and adjust the brightness slider (located just to the left of the audio
playback controls).

Charge the iPad battery
The iPad includes a non-removable lithium-polymer battery that provides
up to 10 hours of use on a single charge. (In fact, Apple claims that 10
hours of video playback, surfing the Web using Wi-Fi, or listening to
music are possible.) You can check the state of the battery by looking at
the indicator in the upper-right corner of the screen ( Figure 1.5 ).
