Magnetic charging loses some energy in the form of heat on both coils.
Technologies like MagSafe lessen the severity of energy loss via ensuring the coils allign, however there is still some energy lost in the form of heat.
This is just a limitation of electromagnetic induction.
It’s a producer of heat placed right next to the battery.
This inefficiency also makes it take more energy to charge your battery. However, I would imagine it’s a nominal amount.
That’s an interesting theory. I’d like to see some numbers because I really doubt that this heating could be anywhere close to the many other kinds of heat produced through normal phone use. Especially considering that you’re unlikely to be stressing the biggest sources of heat in your phone (the screen and the processor) while it’s sitting in a wireless charging cradle. Also, the charging circuits certainly monitor and adjust for this kind of heat dissipation specifically and are able to control it far better than, for example, the sun hitting the screen or a warm pocket.
Wireless charging WILL wear out your battery faster.
For longevity, use a slow wired charger. This will put the least thermal strain on the battery.
How exactly?
Also, my phone charges slower with a wireless charger.

I don’t know but anecdotally I’ve experienced this with every single phone I’ve had that’s been wireless charging.
It just shortens its life somehow. I thought I was crazy. It didn’t make sense unless it does fancy shit with the crystals inside or it heats it badly
That is a deeply unsatisfying non-answer.
