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.

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.
