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 applica-
tions using this function will periodically query the GPS
satellites for your current location; each query drains your
battery.
• Use the Battery saver feature.
