Hey, yeah sure, let's see. I started working this morning at 07:45, it's now 13:45. I had a 20 minute video conference call and watched two 15 minute videos on Youtube. At idle, I had ~3 watts, doing small typing things, coding, I had ~5 watts. During the conference call I had ~15 watts and during the Youtube videos powertop reported ~9 watts.

So have been going for 6 hours, definitely some heavier CPU usage during the conference call and youtube videos, current battery is at 33% and indicates (based on my current usage: updating my blog and firefox'ing around) 3 hours and 45 minutes left.
