§
If the
Sleep mode
option in
Settings > Power
is enabled, at low peak times, your phone will
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
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
§
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
>
Settings
>
Sync, Send & Receive
, and then adjust
the settings under Sync schedule.
§
When you’re not traveling from one place to another, sync weather updates of only your
current location, rather than in all of your named cities. Open the Weather app, and then tap
to edit and remove unneeded cities.
