Manage your display
Lowering the brightness, letting the display sleep when not in use, and keeping it
simple helps save battery power.
§ Use automatic brightness (the default), or manually lower the brightness.
§ Set the screen timeout to a shorter time.
§ Don't use a live wallpaper for your Home screen. Animation effects are nice to
show off to other people but they drain your battery.
Changing your wallpaper to a plain, black background can also help a little.
The less color is displayed, the less battery is used.
For more details, see Settings and security on page 311 and Personalizing on page 95.
Manage your apps
§ Install the latest software and application updates. Updates sometimes
include battery performance improvements.
§ Uninstall or disable apps that you never use.
Many apps run processes or sync data in the background even when you're not
using them. If there are apps that you don't need anymore, uninstall them.
If an app came preloaded and can't be uninstalled, disabling the app can still
prevent it from continuously running or syncing data. See Disabling an app on
page 317.
Limit background data and sync
Background data and sync can use a lot of battery power if you have many apps syncing
data in the background. It’s recommended not to let apps sync data too often.
Determine which apps can be set with longer sync times, or sync manually.
