What do you think about wireless charging?

Question

Since I got a gift of a pair of earbuds with wireless charging, I have been thinking about the energy loss happening during the process.As far as I can tell, wireless charging is (optimistically) 70-80% efficient. Now I agree it hardly matters for small/niche earbuds, but with Apple moving their iPhones [0] to fully wireless Qi charging. I think a 30% waste on that scale (once the ecosystem fallows) could become a problem.What do you think about that waste? Or am I over-blowing the issue?[0] https://onezero.medium.com/dont-be-shocked-if-your-next-phone-has-no-ports-at-all-50a132df0d64

A gimmick. It's wireless but requires zero distance from the charger. It takes longer to charge. The device becomes hot. Inefficient. Requires a level surface and exact alignment to work. Makes the device difficult to use while charging. Need a charger for every device to charge simultaneously.I can't find a single reason to use it over a cable.

i liked it for convivence but moved to a different phone and the case doesn't allow for wireless charging (has some magnets on the case to mount it to metal) so went back to wired.
