Interesting, hadn’t heard of powerstat. I’ll be checking that, thanks!

Agreed, that sounds like the way to go. I was hoping there was already something to do the monitoring for me :)

Thanks, I do like powertop. I think it’s pretty good for short measurements, e.g. over 30 seconds:

% sudo powertop --time=30

The battery reports a discharge rate of 4.17 W
The energy consumed was 125 J
The estimated remaining time is 11 hours, 4 minutes

But in the real world I will not be getting 11 hours of runtime. The moment I start a browser or play a video, power consumption goes way up.
