This is the big issue for most people, I think. I would love to use Chrome, but when I do, (a) thighs burn to a crisp if my machine is on my lap directly and (b) the battery depletes, literally, 1.5x as fast.
Epiphany works pretty well for me, I've been forced to customize the User-Agent string to that of Chrome to make certain things like Outlook Web App treat it like a Real Browser(TM), on occasion I have to use Firefox still (Plex doesn't work in epiphany) but overall it works fine.
I should note that Epiphany is the only Linux web browser that seems to interact with touch screens correctly, drag-to-scroll works wonderfully on my XPS 13 meanwhile Chrome and Firefox just keep trying to highlight text.
I think it's just a lack of optimization for battery usage on OSX Chrome. Google seems to have recently realized it is an issue though and is making progress on improving things: https://plus.google.com/+PeterKasting/posts/GpL63A1K2TF
