I’ve been living in a completely Ubuntu world for over a week now, and am still loving the experience overall. However, one thing has definitely given me pause: Ubuntu clearly consumes more power on my Lenovo T400 than Windows 7 ever did.
Typical battery life for me in Windows 7 was a solid three hours. With Ubuntu, I am getting no more than 90 minutes. That’s about a 50% reduction in battery life – similar to the results posted a couple of months ago by Phoronix.
I love Ubuntu, even if I can’t improve the battery life, so I’ll try some tweaks to see if I can improve the results.
By comparison, PowerWIN is clearly the Dell Mini9 Hackintosh. No spinning disk, no fan, 9″ monitor, and MacOS gives it a typical battery life of well over four hours. I’ve seen it run for over five hours if the monitor is dimmed.
Now I need to close this post. I have only 10% battery left and my PC is about to die.
