Problem
Possible causes
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.
