Two main connectivity options affect the battery life of a BlackBerry smartphone: Bluetooth and Mobile Network. To conserve your battery, you can turn both options on or off (independently of each other) through the Manage Connections screen on your smartphone.
You’ll conserve battery life if you turn Bluetooth off when you’re not actively using a Bluetooth device, such as a headset. If left on, Bluetooth will frequently search for compatible devices in the vicinity, consuming battery power.
Similarly, when a phone is in an area without strong coverage, it constantly tries to reconnect with the Mobile Network, draining the battery. You’ll save battery power if you turn off the Mobile Network when you enter an area with poor or no coverage -- when riding on a subway or an airplane, for example. Just remember to turn the Mobile Network back on to make and receive calls, use the Internet or other communication functions.
To manage connectivity options:
- Press the BlackBerry key to the left of the trackball to go to the main menu
- Click on the Manage Connections icon
- Check or uncheck the boxes marked Bluetooth and/or Mobile Network to activate or deactivate these features
