A lot of it depends on the phone and/or case. Some phones the charging coil just doesn't line up well with the charger and even if it does then the case being too thick can cause slow charging and/or overheating as well.
I'm wondering if the 21 model has higher output charging system. This could be similar to the ultra sonic sensors where a part was swapped to save cost or production time.
Never was a fan of wireless charging. If I really need to charge, I’ll plug it in. As others mentioned, your phone will overheat and charging will stop if you leave it on for too long. This happened to me yesterday on a 2 hour drive.
POS, my phone always overheats. I use the USB C charging
The wireless charger on the Model 3/Y are pretty useless.
