Hey all.

I've heard many and plenty about the power regression in Linux, and also heard that it is back to a good power consumption with 12.04.

According to PowerTop and after a few tweaks, removing Gwibber and UbuntuOne, installing Jupiter, and more - my lappy takes about somewhere between 750 mW to 1.70 W, depending on use. Is it something would you'd consider a good power consumption or bad?


Also, another question: I heard that Linux doesn't treat batteries well and shortens their life span. True? False? fixed?

Thanks.

If it was true, it would be exceptionally good. However, there's absolutely no way your laptop uses that little. Even an ARM machine like a Sheevaplug would struggle to get under 1W. Atom netbooks are about 10-15W, anything with a faster chip will be looking at 20-30W or upwards.

Powertop is obviously not reading your actual use properly.
