Wi-Fi usage and GPS functionality can drain your battery. You
can follow the helpful tips below to help conserve your
battery power:
Use the Power-saver feature in Settings. See Battery.
Reduce the screen backlight time.
Lower the screen brightness.
Turn Wi-Fi, Bluetooth and auto-sync off when not in use.

applications using this function will periodically query
the GPS satellites for your current location, and each
query drains your battery.
