But until Google gets their act together in-terms battery optimisation and efficiency, Chrome will never be a option for me on notebooks. It's not as terrible on Windows as on Mac OS X, but it's still bad. And there has been tremendous issues with Chrome's "Hardware Acceleration" on Windows 10, especially with NVIDIA graphics cards.
It's most obvious with the new MacBook 12-inch. You can slice off 2-4 hours of battery life running the same web content using Google Chrome compared to Apple Safari. And that's with Chrome's pepperflash disabled using about

lugins. The CPU utilisation with Chrome is 80-120% (above 100 means it's running in turbo boost), while with Apple Safari it's rarely above 10%. The difference is quite ridiculous.
Even worse scenarios are Mac notebooks with both integrated and dedicated graphics card, as Google Chrome for some reason insists on activating the dedicated graphics card all the time for no apparent reason. Running Apple Safari compared to Google Chrome on my MacBook Pro 15-inch with Retina sporting the GeForce 650m was quite ridiculous, not only in battery life but even more so in heat and fan noise.
And it's getting really annoying that Google simply refuses to add HLS support in Chrome. It shouldn't be hard to do at all, but they insists on it being a non-standard they simply won't support forcing me to either use services like Twitch.tv with Flash Player, or use another browser entirely.
