I haven’t found a situation where wireless charging is superior to wired charging, especially for my iPhone w wireless charging. The only situation is if you’re out and about and don’t have your cable with you, and in that case the only public wireless charging I’ve ever come across is at a certain Starbucks places, but it wouldn’t make sense in that situation why your own wirelessly mat would help since you probably wouldn’t haul that everywhere with you.
If you wirelessly charge then you have to lay your phone flat on the charging surface, whereas if you use a cable you can hold it and use it normally near the outlet.
