Problem
Possible causes
Possible solution
The phone’s
temperature is below
0°C or higher than 45 °C.
Adjust the battery
charging environment to
avoid extremes of
temperature.
Poor contact between
the battery and charger.
Check all connectors to
make sure all
connections have been
properly made.
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.
