Extending the Battery Life
Active applications, screen brightness levels, Bluetooth and Wi-Fi
usage, and GPS functionality can drain your battery. You can
follow the helpful tips below to conserve your battery power:
Reduce the screen backlight time.
Lower the screen brightness.
Turn auto-sync, Wi-Fi, and Bluetooth off when not in use.
Disable the GPS function when not in use. Most applications
using this function will periodically query the GPS satellites
for your current location; each query drains your battery.
Use the Power-saver feature in Settings. See Battery.
Powering Your Phone On/Off
Press and hold the Power/Lock key to turn on your phone.
To turn it off, press and hold the Power/Lock key to open the

NOTE: If the phone freezes or takes too long to respond, press

phone.
