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
(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?
