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…

Kind of a follow up question:
I faintly remember from college that in a conventional socket charger, voltage is stepped down (are phases altered as well?), rectified to DC and the raw DC again ‚filtered’ as to get a smooth and roughly constant voltage.
Now the induction should deliver AC as well, electronics (usually) and battery charging requires DC so a rectifier is required within the phone – so far so good, but what about the other processes?
Is some of it (voltage, phases, peak amplitude, …) already optimised by the charging device or is additional circuitry on top to charging coil and rectifier required?
Or am I actually overestimating the capabilities of my charger‘s socket and recitifying/filtering/… was already done within the phone all the time before (except for voltage transformation)?
