Tips for extending battery life
How long the battery can last before it needs recharging depends on how you use HTC U Ultra. Try
out some of these tips to help increase battery life.
Use the power management features
§ Turn Power saver mode and Extreme power saver mode on in Settings.
§ Monitoring your battery usage helps identify what's using the most power so you can choose
what to do about it. For details, see Checking battery usage on page 100.
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 Turning location services on or off on page 167.
§ 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 which is the default, or manually lower the brightness. See Screen
brightness on page 168.
§ Set the screen timeout to a shorter time. See Setting when to turn off the screen on page 168.
§ 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. See Setting your Home wallpaper on page 57.
