Problem
Battery will not
charge.
Shortened
standby time
You cannot switch
Possible causes
• The battery or battery charger is
damaged.
• The phone's temperature is below 0°C
or higher than 45 °C.
• Poor contact between the battery and
charger.
• 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.
• The battery is depleted. In
high-temperature environments,
battery life will be shortened.
• 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.
Battery power has been depleted.
Possible solution
Contact the dealer.
Adjust the battery charging
environment to avoid extremes
of temperature
Check all connectors to make
sure all connections have been
properly made.
If you are located in an area
where signaling is weak,
temporarily switch off the
phone.
Use a new battery.
Change your location to one
where the network is
accessible, or temporarily
turn off your phone.
Recharge the phone's battery.
