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:
Use the Battery saver feature in Settings.
Reduce the screen backlight time.
Lower the screen brightness.
Turn Wi-Fi, Bluetooth and auto-sync 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, and each query drains your battery.

To power off, press and hold the
Power

Power

NOTE:

and hold the

phone.
Setting Up for the First Time
When you first power on your phone after you purchase it or
reset it to factory settings (see
