I've spent a few weeks testing the conservative govenor compaed to the ondemand govenor and in my opinion they are both about the same as far as battery usage is concerned (for my usege) however using the conservative govenor had a negative impact on responsiveness due to it being much less agressive in scaling to the max freq.

Edit: I did notice though that the device stayed cooler when multi tasking using the conservative govenor, but not by enough to make it worth using

That said i would still be very interested in testing the conservative govenor again once we have the ability to avoid freqs and adjust the sample rate, as i think it would be much more usefull with a minimal choice of freqs and a shortened sample rate.

for the moment though im sticking with ondemand until the other govenors are fully suported.

It is so amazing that in a few short months overclocking has come from an idea to being fully customizable,
thanks dont even come close to expressing my gratitude for all the work thats gone into this, and it just keeps getting better
