Troubleshooting
Possible cause
The standby time is
related to your network
operator's system
configuration. The same
phone used with different
network operators'
systems will not provide
exactly 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 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.
Battery power has been
depleted.
SIM card malfunction or
damage.
SIM card inserted
improperly.
Debris on the SIM card
contacts.
Solution
If you are located in an area
where signaling is weak,
temporarily
shut
phone.
Use a new battery.
Change your location to one
where
the
network
accessible, or temporarily
turn off your phone.
Recharge the phone's
battery.
Take the SIM card to your
network operator for testing.
Insert the SIM card properly.
Use a soft, dry cloth to clean
the SIM card contacts.
