The worst part of the 6P battery stuff was how shitty Google/Fi support handled it. There was a class action lawsuit, and I just needed to show records of my replacement (and then replacement of my replacement) for that issue. They straight up lied to me in chat about having never contacted support about the issue. I had an interaction that was literally:
You can confirm this is my third Nexus 6P, yes?
Yes.
You can confirm they all came directly from you?
Yes.
You can confirm I only purchased the first one?
Yes.
Why did you send me a second and third phone?
We do not have record of this.
Fortunately, I still had the phone and recorded a video of the phone powering itself off at 65% and was able to provide that as evidence...but I'm still salty about it all. It's why I have not and will not own a Pixel or use Fi ever again.
