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.
