206  Managing Your Device

How long your battery power lasts depends on the battery type and how 
you use your device. Try the following to help conserve battery life:

When the device is not in use, press POWER to switch off the display.

Tap Start > Settings > System tab > Power to open the Power 
settings screen. On the Advanced tab of the Power settings screen, 
you can specify the time before your device automatically turns off 
the display to conserve battery power. For optimum conservation, 
specify 3 minutes or less.

Use the AC adapter to plug your device into an external power outlet 
whenever possible, especially when using a storage card or when 
using a modem or other peripherals.

Adjust the backlight settings. For more information, see “To set the 
backlight to dim after a time delay” in Chapter 4.

Turn Bluetooth off when you are not using it. Make your device visible 
to other devices only when you are trying to establish a Bluetooth 
partnership. For more information about Bluetooth, see Chapter 10.

Lower the volume.

Close battery-intensive programs, such as the Camera, when you 
are done using them. Make sure the programs are ended and are 
not continuously running in the background. Refer to “Using Task 
Manager” in this chapter for information on closing programs.
