Problem
Shortened
standby time
Possible causes
Poor contact between
the battery and charger.
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
Check all connectors to
make sure all
connections have been
properly made.
If you are located in an
area where signaling is
weak, temporarily power
off the phone.
Use a new battery.
