DEVICE FUNCTIONS

EXTENDING YOUR BATTERY LIFE
Active applications, light levels, Bluetooth usage, and GPS
functionality all drain your battery. The following is a list of helpful
tips that can help conserve your battery power:
● Reduce the time your backlight stays on.
● Turn Bluetooth
● Turn Wi-Fi
● 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.
● 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.
● Turn off Automatic application sync.
● Check the Battery use screen to review what features or
functions have been consuming your battery resources.
● Check the Running Services and close any unnecessary
applications.
● Use the Task Manager feature to end/shutdown background
applications that are still running. These minimized applications
can, over time, cause your device to "slow down".
