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.
The list at the bottom of the screen shows the breakdown of battery usage for individual apps and services. Touch a graph for more

completely.
Warning!
If you stop some apps or services, your device may not work correctly.
Battery status (charging, discharging) and level (as a percentage of fully charged) are displayed at the top of the screen.
The discharge graph shows battery level over time since you last charged the device, and how long you've been running on battery
power.
