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.
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
options menu. Tap Power off.
NOTE: If the phone freezes or takes too long to respond, press
and hold the Power/Lock Key for about 10 seconds to restart the
phone.
