NOTE:
If the battery is extremely low, the phone may not power on even
while charging. In this case, charge the phone at least for 20
minutes before trying to power on again. Contact the customer
service if you still cannot power on the phone after prolonged
charging.
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 Wi-Fi, Bluetooth and auto-sync off when not in use.
Disable the GPS function when not in use. Most applications
using this function will periodically query the GPS satellites for
your current location, and each query drains your battery.
