How do I extend the battery life on my ZTE Cymbal 2?
You can conserve battery power by reducing the screen backlight time, lowering the screen brightness, turning Bluetooth off when not in use, and disabling location services when not needed. Location services drain the battery because apps periodically request your location through GPS, Wi-Fi, Bluetooth, or mobile networks. (Page 20)
