Ubuntu battery life vs. WinXP

Postby hartraft » 15/07/2009, 6:40

Hi Guys

First i want to say a big thanks voria for making all these scripts. Ubuntu is a LOT more user friendly now.

However i want to be pretty objective. I used to get close to 7 hrs on winXP for the NC10. I cant achieve that on ubuntu with low brightness, disable bluetooth and disable webcam (so cool to have it under keyboard shortcuts, winblows couldnt even do that :P), underclock to 800mhz etc.

Any thoughts guys?

Thanks


P.S is there a way to set default settings on the scripts on startup? e.g start with 800mhz, no bt, no webcam etc.

I have never really used the NC10 under winXP and cannot tell about the battery life there but under ubuntu on average i get around 5h with everthing on and brightness quite high. No serious work though just browsing, text editor, etc. no video and audio. If I switch the wifi when I don't need it and keep the brightness around 50% i get around 6h.
with video - 3-3.5h
that is my experience.

You should not underclock to 800mhz, but leave the "ondemand" cpu governor: it is better to let the cpu speed up till 1.6ghz for a second than having it working for more seconds at 800mhz. at 1.6ghz you save battery life and you have a faster experience.
