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 tap their On/Off switches.
§
Switch to 2G when you don't need a data connection.
More power is used when you're in low coverage areas. Temporarily turning off
your data connection and switching to GSM network mode uses less battery
power.
To switch to GSM mode, go to Settings and tap Mobile data > Network mode >
GSM only.
§
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. Go to Settings and tap 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 tap > Settings > Accessibility > Dim screen during
page loading.

Manage your apps
§
Install the latest software and application updates. Updates sometimes include
battery performance improvements. See
Updating the HTC Butterfly software
§
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. In Settings, tap Apps > All
tab, select the app, and then tap Disable.
