Do you've a source for this claim? I've always been a believer in slow charging. However, I recently got a OnePlus 12R which comes with a 100Watt charger and charges from 0-100% in 25min. It seems to barely get warmer than my old phone (pixel 4a) with 18 watt charger that took 1 hr 25 min to charge. Not sure if it's due to superior heat dissipation, better battery-ion chemistry or what. Isn't heat the main thing that generally reduces battery life longevity not necessarily fast charging or the wattage it's done at?
I will add that not all fast charging solutions seem to be created equal. Briefly tried a Poco F6 before and that got quite hot with it's 90watt charger. It also sucked the way it's implemented because if you charge while screen is on, it literally doesn't charge fast at all and takes what feels like hours. I mean, I understand the underlying intention why they'd do that but even if you just kept screen on for an extremely light task (like stop watch / timer) - it would refuse to quick charge and resort to doing it slowly, which seems kinda deceptive advertising that as a quick charging device.
From my understanding, only OnePlus / Oppo (and their derived variant products) do it well because they both share same the proprietary SuperVOOC charging protocol tech.
