ha, just saw your story over on ars.
FWIW, I think you're a little credulous there; as I mentioned in my other comment[1], I can't find anything stating that Chrome starting beating Edge at the test (their videos actually claim the opposite) or anybody from Chrome boasting about it (articles from the time like yours[2] also say the opposite).
> On the other hand, pretty easy how such a div might trigger a less efficient path
I mean, sure, you can always fall off the fast path, but given how common transparent divs over video are, the battery benchmark should have come with even more caveats. Edge is the most battery efficient browser†!

I don't think the performance claiming is really the important part here; it's doing something that lacks any real reason but which hurts Edge.
And while I agree that video overlays are common, I also think it's reasonable for such overlays to revert to a slightly less efficient path.
> it's doing something that lacks any real reason but which hurts Edge.
In my own web development activities I can point to hundreds upon hundreds of hidden, invisible, and obscured DOM elements that have no obvious reason to for existing to someone outside the code-base where you find the commen explaining the required work around, browser hack, or legacy constraint. I've also experienced wildly divergent performance on MS browsers compared to others when creating content, often from something as trivial as DOM order or composition.
Clearly Google owes me some money for my part in their ongoing conspiracy to hurt Edge. I'm flexible, I'll accept GCE credit :)

Hey, there's a new div in the DOM, the only possible reason for a change like that is so Chrome can advertise about beating Edge on a benchmark nobody cares about? Even though they never beat Edge on it and this "advertising" never took place?
This was the credulity I was talking about. These events didn't happen (you literally wrote the stories plural! about edge winning the benchmark) and the motivations make no sense. I'm not sure why you'd repeat it without even a warning that it may just be a narrative made up from grumblings about fixing a fast path heard third hand.
Speak for yourself, please.
I do care about video playback battery performance. So much so, in fact, that I bought my current laptop specifically so it would last long when watching videos.
Also note that tablets, smartphones, the Macbook Air and the Surface are sold on their battery stamina, and specifically while watching videos. And how would you measure that? Youtube, of course!
