The phone resets and displays the Home screen. 11.6 Battery Saving Tips How long your battery power lasts depends on the battery type, the network that you connect to, and how you use your device. Try the following to conserve battery power: • When you don't need 3G services, set your phone to connect to your wireless service provider's 2G network. To do this, press HOME > MENU, touch Settings > Wireless controls > Mobile networks, then select the Prefer 2G networks option. • When your device is not in use, press END CALL/POWER to switch off the screen. • Select a shorter idle time before the device screen switches off.
