Yes, that was exactly my point, There are two kinds of ARM, the A and the
M.   "A" is the kind used in you smart phone and the Raspberry Pi and BBB
and these suck up a few watts of power.  The M type is made for low power
and could run off a few AA batteries and the battery shelf life would
expire before the battery was used up.   A simple data logger could keep
the CPU in sleep mode most of the time and then it uses literally a few
micro amps.
