Tips for extending battery life
How long the battery can last before it needs recharging depends on how you use
HTC Desire 820s dual sim.
In times when you need to extend the battery life more, try out some of these tips:
Check your battery 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 Checking battery usage and history
on page 28.
Manage your connections
§ Turn off wireless connections you're not using. Go to Settings to turn on or off
the data connection, Wi-Fi, or Bluetooth.
§ 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 71.
§ 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 and setting the screen timeout to a shorter time help
save battery power.
§ 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.
For more details, see Settings and security on page 86 and Personalizing on page
37.
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. In Settings > Apps, swipe
to the All tab, tap the app, and then tap Disable.
