Optimizing the power performance

How long your battery power lasts depends on battery type and how you use your device.

Try the following to help preserve battery life:

• Tap > Settings > System tab > Power. On the Advanced tab, you can specify when your device turns off to conserve battery power. For optimum

conservation, specify 3 minutes or less.

• Use the AC adapter to plug your device into external power whenever possible, especially when using a Mini-SD card or when using a modem or other

peripherals.

• Adjust the backlight settings.

Set the backlight to dim after a time delay

1 Tap > Settings > System tab > Backlight.

2 Tap the Battery power tab or the External power tab.

3 Select the Turn off backlight if device is not used for check box, and specify the time delay.
