Karmic to Lucid = Less battery

[linduxed]

I upgraded from Karmic to Lucid some time ago and while I've generally been satisfied with the experience, my battery life went down from 7-9 hours all the way down to 3-5 hours.

This is quite an issue considering we're talking about an eeePC, which is supposed to be an unplugged device.

My suite of manually installed packages hasn't changed in any substantial way and my usage habits haven't either.
I've tried using powertop to squeeze out some more life out of the battery (which I pretty much never did before) but no big increases have been noticed.

If you need any data to solve this mystery, I'll provide it as soon as possible.

Not a solution perhaps, but have you tried eeebuntu 4 and seen if you get the same problem?

I have noticed this as well, I use to run windows 7 on my dell studio and get 4 to 5 hours easy, since I installed ubuntu I maybe get 3 hours.

Many people who have upgraded to Lucid have reported this problem. Especially netbook users. I hope tuning the processes running can help. But really need to understand how processor is utilized in this version of Ubuntu. May be we will see a fix for this problem soon.

Try installing Powertop from the repositories. Run it from the command line and it will inform you of what's causing the most "wake-ups", keeping your CPU active. It will also recommend changes to make and better, even do them for you if you wish.

I already mentioned in my first post that I've already tried using powertop, and it's only a slight help. No four hours there.

Personally I think it's either a fault at the core of Lucid, or it's as someone mentioned in the Ubuntu forums, an upgrade issue (when I should have done a clean install).
