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
your phone on
Battery power has been
