I Don't think so that an OS will consume your Battery,
Moreover, The Processes running on an OS can consume it depends on their usage of CPU,

The Following links will help you to last you battery more in Ubuntu > http://ezinearticles.com/?How-to-Manage-Your-Laptop-Battery-in-Ubuntu-to-Make-it-Last-Longer&id=4319612

OSs definitely consume battery. If it is running (the computer is on), then it will consume battery. How much, like you said, depends on what its running a such.


Personally I think Ubuntu is decent with battery life. If anything, I know on one of my laptops, Ubuntu didn't support changing the brightness on my screen and keyboard. Something like that then caused my battery life to run out much quicker than it would on Windows.

In my laptop, the brightness of the screen is always in full-form. So it takes much power. May be it happens to you too. Try to minimize the brightness...

Yes at the moment Linux varies a lot more in power usage. On a supported device it may use less power than Windows. On a device where built in or unique power management features aren't supported it will certainly use more. Also note by default I believe Ubuntu does not install certain disk power management features as they shorten disk life. That is one of the biggest hits on power is the disk being on.

There is a command line utility to measure power usage called powertop. Install it with:

sudo apt-get install powertop

Run it with:

sudo powertop

Yes I think it depends on the hardware as nightwishfan says.

My Acer 1410 gives me 6 hours in win7 and in ubuntu. As long as brightness is turned down.

I can't control brightness in ubuntu. it's always full.. Then i think this may be the reason!!
