Problem
Shortened
standby time
Possible causes
The phone's temperature is
below 0 °C or higher than
45 °C.
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.
Possible solution
Adjust the battery charging
environment to avoid
extremes of temperature.
If you are located in an area
where signaling is weak,
temporarily power off the
phone.
Contact the dealer to
change a new battery.
