Do you have a source? I thought this has been thoroughly debunked.
I wish people would stop using this phrase.
Especially when they couldn't be more wrong.
Heat degrades batteries, wireless charging generally comes with more heat from the lower efficiency.
But at the end of the day it most likely won't matter as people get new phones every few years anyways.
For one, I thought charging slower was better, so could the increased heat be offset by that? Also, it's more heat per joule transferred, but over a longer period of time, is that not better than sudden heat from fast charging?
The constant current phase of fast charging does not generate much heat in comparison at given wattage as it's able to charge up your phone much more quickly at higher efficiency until it switches to trickle charging at ~80%.
Btw, you basically just asked people to know when they are wrong. Seems very optimistic...
I'm genuinely curious but you don't give details or you simply answer with a question...
At any wattage, wireless charging at 70% efficiency will always generate more heat than fast charging at 95% efficiency.
If you want to compare 5w wireless charging to 100w fast charging, even then it's not obvious the wireless charging is better, because it will still thermal throttle and stay throttled for longer, at least a few hours. Meanwhile fast charging will charge it to 80% state of charge in half an hour and then trickle charge to full.
The notion that this is somehow "debunked" is just against physics.

A quick internet research shows the Internet consensus is, wireless charging does not degrade batteries faster. At least it seems there is no empirical data proving otherwise, which at the very least would indicate the difference is small, if any.
I think until I see (good) empirical data proving either of the theories I’m going to stay skeptical.
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.
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...
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.
