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 power it off, press and hold the Power/Lock Key to open
the options menu. Tap Power off > OK.
NOTE: If the phone freezes or takes too long to respond, press
and hold the Power/Lock Key for about 10 seconds to restart
your 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 Settings – Personal – Backup &
Reset), you may need to set it up before using it.
