    Thanks guys,
               I don't know what you did, but after upgrading my laptop 
FC17->FC18 I
saw a 5 hr battery life being quoted - I never saw that long before.
Hello!

It happened to me too. Now I have 4 hours of battery life, when in Fedora 17 used to have around of 2 hours.

Thank you very much people!!!

Same here.
I made a bootable USB stick and installed Fedora 18 on an old Dell1520. Installation and updating was a breeze, no brainer really.
With the previous ubuntu install we could not get battery to above 83% - Fedora it goes to 100% and shows 5 hours life.
BUT I do not think this to be correct. Too many are reporting laptops with 5+ hours.
At 83% battery life was 1 hour and 19 minutes, then at 100% it's 5 +hours.
Will test today
