Possible solution
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.
Use 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.
You cannot switch
your phone on.
Battery power has been depleted.
Recharge the phone's battery.
