Extending Your Battery Life
Active applications, light levels, Bluetooth usage and
GPS functionality all act to drain your battery. The
following is a list of helpful tips that can help conserve
your battery power:
䢇
Reduce your backlight on time. (See “Changing the
Backlight Time Length” on page 64.)
䢇
Turn Bluetooth off when not in use. (See “Turning
Bluetooth On and Off” on page 126.)
䢇
Turn Wi-Fi off when not in use. (See “Turning Wi-Fi
On and Off” on page 152.)
䢇
Deactivate the GPS when not needed. Most
applications using this function will periodically query
the GPS satellites for your current location; each
query drains your battery. (See “Activating Location
Mode” on page 172.)
䢇
When taking pictures, do not use a flash unless you
have to. (See “Camera Settings” on page 119.)
䢇
Do not wait until your battery is completely depleted
before charging your device. Repeating this process
of a complete discharge and recharge can over time
reduce the storage capacity of any battery.
