Why does my computer get less battery life with Ubuntu compared to Windows?

I'm using Ubuntu 12.10 with Gnome 3.6 on a Dell Inspiron N5010 laptop, but I have a problem with the power handling/battery. As soon as I disconnect my charger, the battery starts discharging from an indication of 51% and it lasts for only 1 hour. Compared two hours in Windows 7, this is a major difference.

I've installed Jupiter and I don't see any change. I'd appreciate some help on this, as I would like to keep using Ubuntu now.

  • I had a similar problem with a 2 hour battery life on Ubuntu and 4 on Windows, but then felt that all Linux-based OS's consume a lot of power, sorry for being weird, but practically it does seem so as a lot of my friends' Android phones have similar opinions. – jobin Dec 29 '12 at 09:10

It is likely because your processor is running full at full speed or your graphics card is switch-able but not switching.

You can check and control your processor speed using a widget such as CPU Frequency Scaling Monitor. It fixed my problem with power consumption on Ubuntu 11.04.
