Yes, it is very likely the cause.

Yes, interesting. Sometime ago I've added a lipo battery to test I could 
cleanly surive power outages. When I did shutdown the bbb the battery was 
flat after a few hours which made the lipo route unusable.
I then assumed the pmic still burned some power from the lipo even when the 
bbb was shutdown.

Now I wonder if this has to do with this issue?

just a shutdown now -h  via the acpi  I have a battery on the board too
so it shuts down
gracefully. and when power is reapplied no boot which is not a huge
issue but it still draws enough to keep the
CPU warm.

[beagleboard] Re: Power consumption

2016-06-22 Thread Graham 
I have found that with Debian 8.x
from the command line you have to send "shutdown -hP now"
If you send just "shutdown now" or "shutdown -h", then it leaves the CPU 
running (Doing what, I am not sure.).
the -P option specifically tells it to turn off the power after the 
shutdown.

Command line? what command? 
Or some other way?
