I& #39;ve all but confirmed that it& #39;s specifically the @linkedin web page (that I had kept pinned in my chrome-for-windows) which was chewing up about 40% of my battery life. I closed everything and re-opened all but that, still normal battery draw. Here is the site idle at CPU 15.6%!
the @linkedin tab seems to only be doing some network traffic while as a background tab, so it only occasionally is spiking the CPU, the rest of the time sitting at 0%.
but as soon as I activate the tab, its CPU jumps up to around 10%, and constantly bounces between 8 and 25%.

how could the site possibly be consuming 10-25% of my CPU at all times that the tab is active?
I mean, cliche, we say "oohhh, shitty JS and SPA sites". but no, like, seriously, how could you possibly be so poorly written to consume that much CPU?

the @linkedin site is built on ember... in fact a number of their core devs work there, and they& #39;re a primary incubator/supporter of the framework.
one would presume this site is built somewhat "to spec" of how an ember site should be.
if so, that& #39;s horrifying.

If I wrote a super naive framework that re-rendered the whole page constantly, churning the DOM and everything, causing tons of GC thrashing, etc.... I& #39;m still not sure if I could get it to consistently kill 10-25% of the CPU, constantly, just never ending.
if I was like rendering the entire web page in webgl and rotated in 3d, re-rendered 60fps, and did everything I could to avoid being able to have GPU acceleration, I am not sure if I& #39;d chew through 10-25% CPU.
I& #39;m just sorta stunned. I never could have guessed/admitted/accepted that one single web page could be the culprit of my laptop having literally HALF it& #39;s advertised battery life... ~4-5 hours instead of 9-10.
