Google Hangouts consistently drains at minimum of 20% of my battery life per 30min meeting. It doesn't matter if I'm using my top spec previous generation 15", my top spec previous gen 13", or my 2016 12" MacBook. As such, using it to gauge battery life is about as fair as running a Hadoop cluster in VMs to gauge battery life. Actually, I think the active Hadoop cluster would use less battery. The reason why their test results are ridiculously long is how little they stress the machine. Loading ten basic web pages (in the stock browser, so no Flash, and something tells me no WebGL usage either), so outside an errant background process, what's really using any watts there besides the screen?
