For me it's the exact opposite: I can't get the Linux battery life on Windows without turning Windows down into a stutterfest. Windows is also noisy as hell.

It all comes down to driver support. If you manufacturer doesn't have proper drivers, your experience will suck. It says a lot about Lenovo that open source Linux drivers work better than their proprietary ones, but that probably comes with the territory if you combine Intel and Nvidia.
