Short standby time
The stand‐by time is relevant to the system setup. The phone is
possibly at the place where the signal state is bad. When the phone
cannot receive the signal, the phone will transmit to search the base
station continuously; consuming a great deal of battery capacity and
shortening the stand‐by time of the battery. Please move to the place
where the signal is strong to use the phone or temporarily power the
phone off.
The battery requires replacment with a new battery.
