I just tested battery time in windows, with full brightness as i had in previous tests and i was able to get about 15 extra minutes from windows 10, my guess is that's because windows forced a power save mode when there was under 20% left of the battery charge.
There was no compilation in windows.
I didn't see any major difference but i didn't test settings for maximum battery uptime on any of the OS tested.
I used "ondemand" in linux as it was default setting and also default in windows with the only change being full brightness.
I will try different brightness settings in linux to see how it affects battery uptime.
I don't see anything pointing to an battery drainage problem.

@Kai-Heng Feng is that v15 of the patch series?
Will it be compiled into the kernel or as a module?
