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.
The Internet connection or
the e-mail setting is not
configured properly.
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.
Check your network
connection, and confirm
with your e-mail service
provider if your e-mail
setting has been configured
correctly.
