Possible solution
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.
Cannot turn

Battery power has been

Recharge the phone’s
battery.
