Are you aware of the recent improvements in Chrome 53 energy use? Are your numbers before or after this?

What was your test methodology, or was this ad-hoc?

If there were reliable sources reporting similar numbers it would be easier to swallow, but I can't find a single source that claims it's this bad.

Yes this was within the last couple weeks, using Chrome 55 and Safari 10. The difference is enormous and unmistakeable, if you have an MBP then just try it yourself.

Spotted the Chrome dev.

I don't work for or advocate for Google.

I'm just skeptical about such a massive difference that I've never seen written about, and where only commenters report it, with no methodology, process, or repro steps.

I have a 2012 MacBook Pro with Chrome and anecdotally I don't notice a 3x battery difference with Safari, but I wouldn't make a strong claim about it without some rigor as I mention above.

'Tis the internet! In this case, your experience is everyone else's when it's good, no one's when it's bad.
