    I am using Set CPU with ChevyN01 1100 LV Kernel. One of the choices when setting profiles is "Interactive", what is the difference between this and "ondemand"? which one is better for battery life?

    From what i've read, "Interactive" is a bit more aggressive at ramping up CPU speed based on load, and is slower to drop off to "idle" speeds once the demand has passed.

    "Ondemand" is a bit more conservative in the way it reacts; and will drop back to "idle" speed more quickly.

    "Interactive" makes the device significantly snappier, at the cost of battery life. "Ondemand" will last a bit longer batterywise, however; the device will seem a bit sluggish at times.

    To be fair, it's a bit hard to find the answer to the OP's question in that thread, given that it's over 40 pages long.

    Here's a better thread to explain it, although it's on Cyanogen's forum. The small text at the bottom of the original post explains it pretty good.

    It is sad that I have this post number memorized :)

    OC101 - #287

    That has a very interesting simple sample of what interactive does if used in StandBy mode.
