I don't know much about it but I hate how bad my battery life is on my laptop...
My 3 years old Lenovo X220 lasts for 12 hours (powertop reports so) on Fedora 20 x86_64 with powertop --auto-tune. According to powertop approx. 5.5W is display backlight and 1W is the rest of system.
Just to give a reply that Fedora is not bad on all configs/hardware.
Well until yesterday I didn't know that Fedora didn't install / configure any of these packages. I've installed tlp and powertop, I didn't know powertop did anything other than monitor. I'll see what powertop --auto-tune does. I don't even know if the tlp package has enabled anything either. I wonder if having tlp installed and running powertop --auto-tune will conflict / fight each other...
Time to try stuff out.
You might also look at tuned...
(I think it was mentioned early in the thread).
tuned-adm profile powersave
Also:

Of course it would be nice if this stuff just did the right thing and you didn't have to run any commands or read any guides.
