How can I extend battery life?
Battery life varies depending on how you use your BlackBerry device. To help battery power last longer,
here are some considerations:
Dim the screen
Prolong battery life by changing your device settings to dim the screen.
Do any of the following:
• To adjust the screen brightness, choose a dark-colored wallpaper, or change the screen lock
timeout, on the home screen, swipe down from the top of the screen. Tap Settings > Display.
• To automatically lock your device and dim the screen when it's in a BlackBerry case or holster, on the
home screen, swipe down from the top of the screen. Tap Settings > Security and Privacy >
Device Password > Lock Device When Holstered.
Decrease volume
Do any of the following:
• To decrease the device volume, use the volume keys on the right side of your device.
• To adjust other volume settings such as application volume or notifications, on the home screen,
swipe down from the top of the screen. Tap
Settings > Main Volume or Notifications.
Close apps
Increase how long a single charge lasts by closing any apps or features that you finished using so that
they aren't continuously running in the background. Some features consume more battery power than
others. Close or turn off these apps and features when you don't use them: The camera, the BlackBerry
Browser, GPS, and Bluetooth technology.
Turn off connections
If your device is out of a wireless coverage area, you can turn off the connection so that your device
doesn't search for a network signal continuously. You can also help extend battery life by deleting saved
Wi-Fi networks that you no longer use.
Do any of the following:
• To turn off a connection, on the home screen, swipe down from the top of the screen. Tap
Settings > Networks and Connections.
