Tips Extending Your Battery Life

Here the list what the biggest drain on BlackBerry battery life:

• comes from wireless access
• the screen display (the backlight). The screen generally turns off after inactivity, but persistent use of the backlight can adversely affect the battery.

Tips
If you know that your device is out of range, you can save battery life by turning off wireless access (go to the Applications screen and scroll to the Wireless On/Off icon) until you are back
in a good coverage area.

With Bluetooth-enabled devices (such as the 7290), you can save power by turning off Bluetooth if you do not plan to use Bluetooth capabilities.
