You can also prolong battery life by adjusting the brightness and timeout of your BlackBerry smartphone's display.
To adjust the backlight brightness and timeout:
- Press the Menu key and select Options
- Select Screen/Keyboard
- Highlight the number beside Backlight Brightness and choose a level that is comfortable (60 is optimal), then select
- Highlight the number beside Backlight Timeout and choose a time that is comfortable (20 sec. is optimal), then select
- Press the Menu key and select Save
Also, returning the smartphone to its holster when it's not in use will power off the screen to conserve power regardless of the phone's settings.
