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.

Here’s a fun fact: phone manufacturers know this. So what they call “100%” is not actually 100%. Your phone will not charge your battery to full. Battery charging is already designed around this.
That depends on the manufacturer, some do, some don’t. My phone has a setting to control the max charge, so I set it to 80% when I got it.
Yes, but that 100% is not really that. It has been programmed to display that percentage, when i reality its 80%.
No, I’m saying that not all manufacturers have that limit, and it’s a relatively new setting (last few years). If you have an older phone or something not from the top few manufacturers, it might not have that feature.
This is like spinal tap. Yeah but my phone charges to 110%. I don’t think you understood what they’re trying to say. Changing what 100% means isn’t a setting or “relatively new”
I’m saying when your phone charges to 100%, some manufacturers take that to mean 80% of capacity, whereas others actually charge the battery to 100% of capacity.
Exactly, which is neither a user setting or relatively new. Battery manufacturers have always had to decide what voltage is what state of charge (percent).
The user setting where you limit it to 80% is on top of what the previous commenter was describing
Sure, if the manufacturer sets it to not charge to the max. I’m saying some manufactured charge to the max by default, hence why that setting is useful.
I think you’re leaning too much into the false assumption that “the max” is some final and definite thing.
Batteries aren’t charged from “empty” to “max”, there is no “max”. They’re charged from one voltage level to another which isn’t in a percentage value. How do you think your phone knows what percentage a battery is at?
No, they’re saying that some hardware manufacturers report 80% as 100% (as you noted) while others do not. Just like some manufacturers report 5% as 5% while others report 10% as 5% with the realization that most people misjudge when they’ll be able to charge.
