With the same sort of light interactive usage, Battery life has gone from ~4 hours to 2:45 or so. Running powertop shows the system in P-state "Turbo mode" 10-15% of the time. Typically this was almost zero in maverick, 98+% of the time maverick was in the lowest state. wakeups reported in the 5-600/s range where previously (from memory) it was 200 ish. i915 driver is high on the list. This is irrespective of whether running unity or classic desktop.
