"This is hardly Linux's fault. <INSERT_MANUFACTURER_NAME_HERE> just didn't bother writing (proper) drivers."

The thing is, as a customer, after a certain point I just don't give a crap. Like, when I was a teenager it was super fun to spend entire days fixing esotheric problems with hardware and rebuilding the kernel to suit my needs, but nowadays I want to hit the power button and work. Linux is not that, at least not for me, I do use Mint daily on an older Dell laptop and that is 90% fine but for any "serious" development I would always use my Windows machine + VS.

When I buy a computer I specifically choose one with good linux support rather than buying a random computer and hope it works properly. I bought a Lenovo X1 Carbon, and I've had a Lenovo T430s, along with a Lenovo T61. All of them worked great.

Asus Zenbook UX330C - Ubuntu 16.04 64bit / stock kernel / i3wm - No TLP or power tweaks or additional powertools - 88.97% remaining 8hr30mins - and that's pretty accurate.

I think you just have a bad SKU of a laptop if Linux gives you 1hr and Windows only 2.5hrs.

Down to 76% now, so pretty accurate. That with Chrome with several tabs, and a GPU/CPU heavy application called Slack/electron running.

Message to OP try 16.04.2 LTS (or a later version) and I think you'll find very different results with Asus laptops and Ubuntu.

That's actually amazing, lucky you! I'll give the new LTS version a go for sure as I still love ubuntu!
