Tune performance
Optimize battery life
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.
Extend the life of your battery
If you aren't using Wi-Fi, 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.
