Turn off radios that you aren’t using.

If you aren’t using Wi-Fi, Bluetooth, or GPS, use the Settings app to turn them off. See“Wireless & networks settings” on page 91 and“Location and security settings”on page 96. (The GPS receiver is only turned on when you’re using an app that makes use of it.)

Turn down screen brightness and set a shorter screen timeout. See“Screen settings”on page 96.

If you don’t need them, turn off automatic syncing for Google Mail, Calendar, Contacts, and other apps. See“Configuring account sync and display options”on page 81.

Use the Quick Settings to check and control the status of radios, the display brightness, and syncing. See“Status Details and Quick Settings”on page 20.

If you know you won’t be near a mobile or Wi-Fi network for a while, switch to Airplane mode.

You tablet uses extra power to search for mobile networks. See“Status Details and Quick Settings”on page 20.
