Greeting, I did not have any issue with the battery life in Fedora 17, but after upgrading to 18 battery life has been a bit too short. I am sorry, but I can not really trace back when the problem started. I waited for F19 hoping this could be fixed, but it did not.

Anyway, in few days, the battery duration dropped from 4-to-5 hours of duration to a mere 2 hours. Simply put, the average temperature of the hardware also increased a lot, and the fan is always spinning.

I am using powertop, everything seems in "Good" state, but reported battery drain is over 40W, while with F17 it was like, on average, 20W or even less.

But I am no expert when it comes to battery management, so... Aside from powertop, where should I look to check what is wrong?

you can open task manager and chek out for any pappications consuming high cpu....power wise there is no difference between 19 and 17. I was using xfce 17 then jumped to 19.........

I've seen nautilus's usage jump to 100% a few times, which significantly reduced my battery life, there seems to be a bug or something so I just have to kill it when my computer seems slugish.

I wud suggest you to roll back to 17 or 18 (since there is no support for 17 i am forced to move to 19 but i am more comfort on 17)

Have you tried using PowerTop. It is hard to give a meaningful comparison "before" and "after" but I think this tutorial is pretty good. you just have to use the equivalent Fedora command "yum" instead of "apt-get"

Yes, as I said I am already using it. As a personal remark, I would like to say that in PT 2.4 there is - sadly - no more reportage on (milli)watts used by each application, but there are only events count. Probably more precise, but does not really give the idea.
