Manage Your Connections
Turn off wireless connections you're not using. To turn on or off connections such as
n
mobile data, Wi-Fi, or Bluetooth, go to Settings and touch their ON/OFF switches.
Turn GPS on only when a precise location is needed. To prevent some apps from using
n
GPS in the background, clear the Device sensors option in Settings > Location > Mode.
Select it only when you need your precise location while using navigation or location-based
apps. For more information on location services, see Location Settings.
If the Sleep mode option in Settings > Power is enabled, at low peak times, your phone will
n
turn off the data connection after the screen has been off for 15 minutes and there's no network
activity (no downloads, streaming, or data usage). The data connection resumes when you
switch the screen back on.
Turn on Airplane mode when you don't need any wireless connections and you don't want to
n
receive calls or messages. For details, see Airplane Mode.
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.
n
Set the screen timeout to a shorter time.
n
Don't use a live wallpaper for your Home screen. Animation effects are nice to show off to other
n
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.
Set the Web browser to auto dim the screen while webpages load. Open the Internet app, and
n
then touch > Settings > Accessibility > Dim screen during page loading.
For more details, see Display & Gestures Settings.
Manage Your Apps
Install the latest software and application updates. Updates sometimes include battery
n
performance improvements.
Uninstall or disable apps that you never use.
n
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. See Uninstall Third-party Apps.
If an app came preloaded and can't be uninstalled, disabling the app can still prevent it from
continuously running or syncing data. In Settings > Apps, swipe to the ALL tab, touch the app, and
then touch Disable.
