It’s all about the heat. It’s not dumping 120w non stop even over 90% for example. OnePlus also use supervooc not standard usb pd. My phone legit does 150w max and while I mostly use my 80w charger because my tablet uses that I can’t say my battery seems affected much 2,5 years in.

2.5 years isn’t that long to evaluate battery degradation IMO, and as you said, you mostly don’t even push your battery that hard. And the article even seems to imply that faster charging does impact battery life, it’s just that manufacturers consider 100w a sweet-spot between charging speed and battery degradation.
