Check Power Usage
Monitoring your battery usage helps you identify what’s using the most power so you can
choose what to do about it. For details, see Check Battery Usage.
Manage Your Connections
● Turn off wireless connections you’re not using. To turn on or off connections such as
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 GPS in the background, keep the GPS satellites setting off. Turn it on only when
you need your precise location while using navigation or location-based apps. In
Settings, touch Location to turn this setting on or off.
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.
● Set the Web browser to auto dim the screen while webpages load. Open the Internet
app, and then touch > Settings > Accessibility > Dim screen during page loading.
For more details, see Display, Gestures & Buttons Settings.
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. 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.
