Charging wirelessly on iPhone is useless as it’s extremely slow. Unless you’re planning to leave your phone wirelessly charge overnight. Whenever the wireless pad tends to heats up, it slows down the charging a lot.

I’ve use USB meter to measure the charging wattage on wireless. There is plenty China brand made with cooling fan built in that charge 10W manage to charge iPhone close to 9W. While my Samsung Wireless Charging duo only manage around 7W at most while my Note10 Plus is pulling 15W top.
