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:
• Use the Power manager feature in Settings.
• 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.
