3.5. Power Saving

3.5.1. Sleep Mode
The module is able to reduce its current consumption to a minimum value during the sleep mode. This
chapter mainly introduces some ways to enter or exit from sleep mode. The diagram below illustrates the
current consumption of the module during sleep mode.

Details
Software is active. The module has registered on the network, and it
Idle
is ready to send and receive data.
Network connection is ongoing. In this mode, the power consumption
Talk/Data
is decided by network setting and data transfer rate.
AT+CFUN=0 can set the module into a minimum functionality mode without
removing the power supply. In this case, both RF function and (U)SIM card will be
invalid.
AT+CFUN=4 can set the module into airplane mode. In this case, RF function will
be invalid.
In this mode, the current consumption of the module will be reduced to the minimal
level. During this mode, the module can still receive paging message, SMS, voice
call and TCP/UDP data from the network normally.
In this mode, the power management unit shuts down the power supply. Software
is not active. The serial interfaces are not accessible. Operating voltage
(connected to VBAT_RF and VBAT_BB) remains applied.
