Battery life varies depending on how you use your BlackBerry device. To help battery power last longer, try any of the following:
Prolong battery life by changing your device settings to dim the screen. 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.
Turn down the device volume with the volume keys on the right side of your device.
To adjust other volume settings, on the home screen, swipe down from the top of the screen. Tap Settings > System Volume or Notifications.
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 and should be closed or turned off when not in use. For example, the camera, the BlackBerry Browser, Voice Control, GPS, and Bluetooth technology.
If your device is out of a network coverage area, turn off the connection so that your device doesn't continuously search for a network signal.
To turn off or change network connections, on the home screen, swipe down from the top of the screen. Tap Settings > Network Connections.
You'll often gain a boost in power savings by using the latest version of BlackBerry Device Software. If a software update is available for your device, a notification appears in BlackBerry Hub.
Reduce power usage by keeping less data on your device. Save data to a media card instead of your device storage.
Conserve more power by turning off the camera flash when taking pictures.
