The N6 log issue doesn't work for our 6P's and I saw the same article. I've been researching this issue for weeks now.
I'd still contact Google support as they said they would even get me an exception if they needed too, (helpful guy) so there is always a chance since the device would only just be about a month out of warranty if so.
Also in a 2nd rundown test here at work, I was able to stream some YouTube video from 25% down to about 2% before it shutdown, so now I am back at a conundrum that it may possibly be a Software issue? Or with Power Saving on, it might not be drawing enough voltage that it forced a shutdown until the very end for once? Or I dono, more testing is needed, and I will be testing the absolute crap out of my refurb replacement as well as I am not letting go of my baby without knowing the replacement is better. (Speakerphone mic or not).
