Possible Causes
Possible Solution
Battery not
charging
The battery or battery charger is
damaged.
Contact the dealer.
The phone’s temperature is
below 32°F (0°C) or higher than
113°F (45°C).
Adjust the battery charging
environment to avoid extremes
of temperature.
Poor contact between the
battery and charger.
Check all connectors to make
sure all connections have been
properly made.
Shortened
standby time
The standby time is related to
your service provider system
configuration. The same phone
used with different service
providers’ systems will not
provide exactly the same length
of standby time.
If you are located in an area where
signaling is weak, temporarily
power off the phone.
The battery is depleted. In
high-temperature environments,
battery life will be shortened.
Contact the dealer for a
new battery.
If you are not able to connect
to the network, the phone will
continue to send out signals as it
attempts to locate a base station.
Doing so consumes battery
power and will consequently
shorten standby time.
Change your location to one
where the network is accessible,
or temporarily turn off your
phone.
