I usually keep the battery between 20% and 70% in my everyday use. Sometimes charge up to 90%. I try and not let the battery sit too long above 90% or below 20%. These seem to be pretty good rules for battery health without being too annoying. I've also heard somewhere there is a specific stress point in this particular Polestar battery at 70%, so try not to let it sit too long right there either. But ultimately I don't overstress any of it. Haven't seemed to lose much range at all over almost 3 years, even predominantly fast charging.

I remember the Out of Spec video where Kyle Conner said that a polestar engineer told him there was a 70% 'stress point' but I have never seen anything else about it anywhere. Has there ever been another source for this claim?

Yes, this is the same place I saw it too, and the only time I've heard it. Doesn't sound like something you'd just make up, and also something Polestar might not want to be putting out there themselves. It may be hooey but I do try and avoid my car sitting at 70% just in case.
