Adjust the battery charging
environment to avoid extremes of
temperature.
Poor contact between the battery and
charger.
Check all connectors to ensure that
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.
Cannot turn your
phone on
Battery power has been depleted. Recharge the phone’s battery.
