Standby duration shortened
Standby duration is related to system
settings of network. It is recommended
that you turn off your device in area
with no signal reception to save
battery.
Replace battery.

continuously search for a base station,
thereby consume great amount of
power and shorten standby time.
Please move to a strong signal place
or power off your device temporarily.
