I have the impression that the power usage of my machine is lower after a fresh reboot, compared to when the MBP has been running without reboot for several days.
I didn't do any sophisticated testing, no benchmarking. What I've been comparing is the power consumption in Watts as reported by coconut battery and my own monitoring tool. Essentially the information is read from ioreg in both cases. Anyways, the power consumption while web browsing using Safari is around 10 W after a fresh reboot, with occasional spikes when opening many new sites or things like that.
Before I did the reboot, it seemed to be sitting around 12 W, again with (higher) spikes when browsing more demanding websites. This might seem negligible, but it's a difference of about 1.5 hours from a full battery.
So, this might very well just be due to a different browsing behavior before/after the reboot. As I said above, I didn't do any precise benchmarking. I was just wondering if someone else has made the same observation.
In case anyone wonders:
Brightness 12/16
Keyboard backlight on, 8/16
Running programs: Safari (no flash installed!), Dropbox client, iStat pro and weather widget, coconut battery
