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 58.
䢇 Turn Bluetooth off when not is use. See “Turning
Bluetooth On and Off” on page 122.
䢇 Turn Wi-Fi off when not is use. See “Turning Wi-Fi On
and Off” on page 148.
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 169.
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.
䢇 Turn off Automatic application sync. See
“Synchronizing Accounts” on page 61.
䢇 Use the Power Control Widget to deactivate hardware
functions such as Wi-Fi, Bluetooth, GPS,
Synchronization, or LCD brightness setting.
䢇 Check the Running Services and close any
unnecessary applications.
