v4.1.x-ti is the best, but just tested v4.4.x-ti this morning:

at idle:

  current CPU frequency is 300 MHz (asserted by call to hardware).
  cpufreq stats: 300 MHz:60.64%, 600 MHz:2.75%, 800 MHz:0.00%, 1000
MHz:36.60%  (14)
root@beaglebone:~# uname -r
4.4.8-ti-r22

5v @ 0.15~0.18 Amps on my jumpy power supply...

echo mem > /sys/power/state

5v @ 0.05 Amps

bbb: rev a5a, just a ftdi serial cape attached.
