nrf5340 sleep currrent consumption

[Lavanya_Manohar]

In our custom board nrf5340-nrf7002, tried system_off(C:\ncs\v2.6.1\zephyr\samples\board\nrf )sample to check power consumption. 

But it measures 0.60mA

Is there any config need to address? please provide debug steps

Hello,

What is the base-current consumption of your board when everything is in sleep mode? 

You have flash and i2c on your board. So, there must be some added current from other parts of your custom board.

When we have flash a simple sample(with counter+LED) in our custom board, board consume overall 28-33uA. 

When we add wifi+Task+interrupt+ble+i2c related code to the same code the overall board current goes upto 60-70uA

Could you please shrae the detail of how much it consume(current measurement) when we add peripherals? So that we can conclude the PM of our board.
