how do wireless chargers work?

Question

Charged my smartphone on a wireless charger and I’m convinced it is black magic or witchcraft. It barely charged (sitting for 4 hours, only went up by 10%.) I assume it has something to do with electrons…

That seems quite low. The phone may not have been properly aligned with the charger.
