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 Battery saver feature.
Powering Your Phone On/Off
• Press and hold the
Power
key to turn on your phone.
• To turn it off, press and hold the
Power
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
key for about 10 seconds to restart the
phone.
