Controlling the OS is probably a big help there. At least, I saw lots of complaints about my zenbook model’s battery not hitting the spec. It was easy to hit or exceed it in Linux, but you have to tell it not to randomly spin up the CPU.

I had to work my ass off on my Fujitsu Lifebook to get 90% of the estimate, even on Linux. I even worked on a kernel patch for the Transmeta CPU, based on unexploited settings in the CPU documentation, but it came to no or negligible difference in power draw, which I suppose is why Linus didn’t do it in the first place.
