As a crude data point of idle system running a full kde desktop environment on
powersave with minimal backlight and just chatting on IRC I find it's just
under 10% battery life difference. I have confirmed in the past the accuracy
of the remaining capacity exported by the battery and the time to complete
discharge. This saving is similar in magnitude to the 1000->100Hz savings of
7% mentioned on other threads. While nothing like the 25% initially suggested
it is still significant. Anyone with a more accurate means of testing this
interested?

Cheers,
Con
