Do you have evidence to support that claim? Batteries and charging technology have come a long way over the years.
I don't care enough to dig up the specific article for you, but if you have the patience to do it yourself, check out Battery University. It's in there somewhere, along with all sorts of useful info regarding battery technology, all backed by scientific research.
Bookmark the site and refer to it often. You'll learn a lot of neat things.
This site doesn't appear to definitively support your statement. The secton on ultra-fast charging, which appears to be written in relation to EVs rather than phones, does state that high temperatures and charging over 80%/keeping a battery at 100% can be detrimental to a battery's lifespan. However, the "scientific research" it claims to reference is nearly a decade old and so there is no mention of the advancements in cooling and charging technology that have occured in that time. It's the equivalent of someone basing their opinion on the technology that existed when the Galaxy S7 was a new phone. Most (all?) phones come with battery regulation features built into the software now, and there have been many improvements made to internal ventilation and heat distribution as well as the chargers themselves. I'm not convinced it's as clear cut as you're making it out to be and this extremely outdated website certainly doesn't support your argument.
The way those super-fast charging batteries work is usually by splitting the battery internally. It's not one battery charging at 120W, it's 2 charging at 60 (or 3 at 40).
