As they note at the end, this only applies to OS X with QuickTime, but not to Windows 10 on the same hardware. So while it may be an obvious optimization to some people it doesn't seem to be implemented everywhere it could be. Or the DWM is more efficient than OS X's window composition stuff and there's no difference between windowed and fullscreen modes. Either option probably will annoy some fanboys one way or the other. One thing that they may have done is to simply change the refresh rate of the display to match the played video's (akin to GSync/Freesync) in fullscreen mode. You can't do so in windowed mode since it will affect other applications, but when a fullscreen video is shown you can safely do so and it may save a bit of power.

  They should have tested with the 'movies and tv' app that is now the default video player in windows 10. From benchmarks I recall seeing, it's by far the most battery efficient video player on the windows platform. edit: http://www.pcworld.com/article/3023430/hardware/tested-vlc-vs-windows-10-video-player-the-winner-may-surprise-you.html http://www.pcworld.com/article/3023430/hardware/tested-vlc-v...

    Interesting, and I'm curious why its like that. The only thing being tested is 4k video though. More tests are needed beyond 4k. Case in point: I don't own a mobile Windows device so it doesn't matter to me. On my MBP (2880 x 1800) 4k wouldn't apply either. I'd run either XviD or DVD.

    Windows media Player is actually deprecated on Windows 10 (2015) and you actually have to make special efforts to use it.

DWM is gimped compared to Windows Vista/7 for battery life reasons. That’s why blur (Aero theme) went away in Windows 8. Apple started implementing variable refresh in iPads, but not on their Macs as far as I know.
