Standby
duration
Shortened
The standby duration is relative to the system setting of
network. While the mobile phone is in an area with poor
signal strength and cannot receive the signal, the handset will
continuously search for a base station. This will significantly
reduce battery charge. It is recommended that you turn off
your mobile in area with no signal reception to save battery.
Need replacing the battery. Please change a new battery.
