Troubleshooting
Possible causes
The length of standby time is
affected by your service
provider's system
configuration. The same
device used with different
service providers' systems does
not have 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 device will
continue to send out signals as
it attempts to locate a base
station. Doing this consumes
battery power and
consequently shortens standby
time.
Your device is in Airplane
mode with no wireless
connectivity.
The signal strength is not
strong enough.
Possible solutions
If you are located in an area
where the network signal is
weak, temporarily turn off your
device.
Use a new battery.
Change your location to one
where the network is
accessible, or temporarily turn
off your device.
Touch the status area on the
status bar and clear the
Airplane mode check box.
Try moving to a different
location for better signal
reception.
