TL;DW: Fast charging over 2 years only degraded the battery an extra 0.5%, even on extremely fast charging Android phones using 120W.
And with that, hopefully we can put this argument to rest.

I always thought that charging beyond 85% or so is what degrades batteries. The LiPos of my quadcopter actually actively reduce their charge if left sitting somewhere for a longer period of time. To prevent them from going up in flames.
It does, but the battery charge controller in your phone already does that. What it shows you as 0-100 is 20-80 of the actual battery. Others may or may not.
Do you have more info on that?

3.7v is 0%, 4.2v is 100%. But a lithium battery can go higher and lower, it’s just that doing that can harm the battery, perhaps spectacularly. OEMs just narrow the voltage range to extend life. When you set a charge limit, it narrows that range further.
