It's my understanding that even with Apple's battery-saving tech, charging batteries that fast tends to degrade them faster. I don't understand the difficulty in just charing them with a humble 5-watt charger overnight while one is sleeping. I have an external battery pack to charge my devices when traveling when there are minimal charging options.
All fast chargers charge at a variable rate. They charge that way to mitigate battery degradation. Apple is being ultra-ultra-ultra conservative with their fast charging. They can afford to do so because their customer base is accepting of their pace of development of charging tech. Also Apple's customer base primarily operates from a perspective of slow charging: 5W for years and years so any improvement seems like it's a big improvement.
Fast charging will degrade a battery quicker than low power charging. Just how much more degradation, and how quickly it would occur, is the real question. Charging tech has come a loooong way outside of the garden. Without getting too far into the weeds, here's an easy read look at fast charging that's not from Apple. https://www.androidcentral.com/warp-charge
FYI - the "charger" does not determine the rate. The device decides how fast it charges (charging circularity is in the device), up to the maximum juice/rate the "charger" can provide. The "charger" you plug into the wall, that has a USB-A/USB-C connection is just a power supply. The correct name for it is "Power Supply" - it only provides a power source, up to its maximum rated capacity.
Also, some of "% battery health" is the battery lottery. Batteries are chemical devices. Even with good QC, and the best attempts at making all of them identical, there are still some variances. I build RC battery packs. I might order 20-50 cells of a good brand name (Panasonic, Sony, Samsung) and make sure they are real (not knockoffs). I bin the cells by their capacity. I don't want to put a "lesser" cell in a pack with cells that have more capacity - the pack will trend toward the lowest common denominator, the weakest cell.
Heat is a big battery killer. It can occur when fast charging, leaving in a car, leaving in sunlight, heavy use for extended time (heavy game playing). This most likely affects iPhone batteries more than Apple's charging settings.
To be fair, he didn't claim the charger decided anything.
Modern fast charging requires chips in the chargers, phones and cables.
Yes, heat and cold can affect battery health and performance but all the fast charging devices I've used have never shown any worrying degradation over time. In fact they have always performed splendidly. So much so that the notion of fast charging and battery health issues have long been forgotten.
I guess "All fast chargers charge at a variable rate." means something different to you & me. The power supply is not a charger. It is a power supply. It negotiates with the charging circuitry inside the devices, to provide voltage/amperage the device needs. It then provides that, unless the device re-negotiates. The power supply generally changes nothing - it is all managed by the device. (I should say I've seen power supplies that will attempt to renegotiate the available voltage/amperage, or just start limiting the current, if the power supply is getting hot, but this is not the norm.)
Regarding charging rates vs. heat, generally the faster you charge, the more heat that is generated. If the battery is heating up, that will affect longterm battery life. But as you said, most modern devices manage battery charge speed/heat so as to try & not affect the battery's longevity.
I think it's splitting hairs to say a power brick is only supplying power and not charging.
They are one and the same in terms of language usage.
It is not. People may not know the difference, but that doesn't mean they are correct. They are not one and the same, except for ignorant people (meaning they don't know any better.)
Perfect example - your iPhone is full. if the power brick/supply was doing the charging, it would continue to try & charge the battery, damaging it. It can't - the charger & intelligence is in the device. The brick is purely a power supply.
Same applies to electric vehicles (I own two). Charger is built into the car. The "charger" cable that's connected is merely a power supply/source. I often have to explain this to people...
You mention electric cars. I have had electric cars in my family for years.
They can be charged from home but require charging points. That is the official name. They are not called 'power supply points'.
Even Tesla does not use the term power supply points.

I understand that languages evolve. I generally use the dictionary to determine what they mean today (so should others). Below are Webster's Dictionary listings for "charger" & "charge". Neither mention a power supply. Both state something that applies a charge into a battery. The battery charger in the device is that does this (or not, if it's full - it manages the charging).
When the dictionary changes the definition, I'm glad to follow, even if it's technically incorrect.

When it refers to 'charger', it isn't referring to what is in the car even if the car is managing the charging.
And Renault uses the word 'charger' openly:
"An easy way to find out which electric car chargers are suitable for your electric or plug-in hybrid vehicle is to check the handbook."
