You can extend your battery's life between charges by turning off
features that you don't need. You can also monitor how apps and
system resources consume battery power.
To adjust the settings described here, first touch the Settings icon
on a Home or All Apps screen.
Extend the life of your battery
 If you aren't using Wi-Fi, Bluetooth, or GPS, use the Settings
app to turn them off. The GPS setting is located in Settings >
Personal > Location services.
 Don't leave the Maps or Navigation apps open on the screen
when you're not using them. They use GPS (and thus more
power) only when they're running.
 Turn down screen brightness and set a shorter Sleep timeout:
Settings > Device > Display.
 If you don't need it, turn off automatic syncing for all apps:
Settings > Personal > Accounts & sync. Note that this means
you need to sync manually to collect messages, email, and
other recent information, and won't receive notifications when
updates occur.
 If you know you won't be near a mobile or Wi-Fi network for a
while, switch to Airplane mode:
Press and hold the power switch until the Tablet options dialog
appears. Then touch Airplane Mode.
Check battery level and usage details
 Open Settings > Device > Battery.
