My BPI M2 board current consumption is about 80mA in off state. Everything was disconnected form the board after power down, only the battery is connected. It is too high so I measured the power supply voltages that are available on test points.
All the other power supply should be 0V, however VCC_3V0=0,802V VCC_5V=3,8V
(VDD_GPU, VDD_CPU, VDD_SYS, VCC_DRAM,VDD_CPUS = 0V)
I think this causes the high off state current. In off state only RTC should work, so idle current must be a few mA. I will use the battery to supply the RTC in off state and for correct power-off in case of missing external power. Anyway the board works perfectly, probably we will use it in our product as a web interface for our instruments.
What is the off state current of your boards?
