TROUBLESHOOTING
Problem Possible causes
The standby time is related
to Consumer Cellular
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.
Shortened In high-temperature
standby time 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.
