other factors like usage time, intensity of use, and charging habits also have effects on the lifespan, so it’s hard to compare one person’s experience to a single other persons and draw a conclusion that’s anything other than anecdotal without some very specific controls.
what i do know for certain is that the heat generation from wireless charging has been long studied, and so has the effect of those heats on li ion batteries.
I have exclusively charged my phones wirelessly for about a decade. My batteries typically end up healthier than my wife’s over a long period of time.
So sorry about your wife’s battery

I don’t doubt there’s a difference, I just don’t think it’s noticeable.
