@adick i think you find it's the vfs cache pressure that is making the difference i noticed no difference with the powersave bias but changing the vfs made the most improvenments
(Nitpick: "mAh per hour" is a... peculiar unit, just say mA ;-) ) If powersave_bias has any effect at all it would only be when the CPU is being actively used enough to trigger a frequency change. As 10mA is an idle current draw, comparing that to measure powersave_bias effects is useless.
@ a dick... I too also use the same frequencies and notice a slightly longer battery life but how do i change the powersave_bias?? Is 110 the optimum range u've tested it in ??
