BBB low power (minimal current)

What is the minimal current value possible with BBB in the low power mode ?
What is the minimal current value on each low power modes and conditions ?
Tks and regards

You need to experiment with different settings and CPU speeds. I use 220mA for average draw on a BBB remote hacking drone w/o wifi or a monitor. You need to decide if power saving is more important than performance before you consider dropping cpu speed.

Of course there are many conditions to low power.
My question is about limits. How is the minimal value for BBB, and what conditions ?
Motivation is to dimension and possibility to use battery.
