Tell HN: Gmail on Chrome eating battery

At some point over the past 4 months or so, my battery performance started to degrade from about 4 or 5 hours to about 2 or 2.5 hours. I figured it was just the realities of a 3.5 year old MBP Retina.

But I was debugging an application locally (on Ubuntu, I dual boot) for performance and I noticed that one of the Chrome processes was sitting at 150% CPU, after some testing I determined it was the Gmail tab on Chrome. Now, by keeping Gmail closed when I'm not using it, my battery lasts almost as long as it used to.

I know I'm not the only one that primarily works from coffee shops and libraries, plus I figure the Gmail team might be on here, so that's why I'm sharing.
