Manage Your Apps - HTC One A9 User Manual

103 Power and storage management
Manage your connections
§ Turn off wireless connections such as mobile data, Wi-Fi, or Bluetooth when not in use.
§ Turn GPS on only when a precise location is needed, such as while using navigation or
location-based apps. See
§ Turn on Airplane mode when you don't need any wireless connections and you don't want to
receive calls or messages.
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.

Manage your apps

§ Battery optimization helps extend battery standby time. See
on page 101.
§ 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
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.
§ In Settings, tap Accounts & sync and check what types of data are being synced in your
online accounts. When the battery is starting to run low, temporarily disable syncing some
data.
§ If you have many email accounts, consider prolonging the sync time of some accounts.
In the Mail app, select an account, tap
the settings under Sync schedule.
