I give up. I'm curious, you are clearly not.
Why does everyone seem to disagree with you?
Does the fact that the copper coil get hot instead of the battery itself have any influence?
Do you have empirical data?
Etc. Etc. Just some examples, from the top of my mind...

When one is curious they tend to find the answer out themselves.
Copper coil in phones are next to the battery, it's going to heat up the cells.
I've already sent you one link and you've not acknowledged it. Good luck in your epistemic endeavors.
For any given wattage, wireless charging will always generate more heat.
It really isn't more difficult than that. You don't need to be skeptical about physics.
I've already addressed in my first post the differences are likely marginal, as people get new phones within a few years anyways. Doesn't mean additional degradation didn't happen.
