Wireless Charging Works with Most iPhone Cases
Wireless chargers work through magnetic induction, which helps connect your iPhone with a weak magnetic pull while also initiating the charging current.
You can tell when the wireless charger is working by keeping on eye on your battery symbol or watching the lock screen and making sure that its charging indicators are on.
The good news is that this magnetic induction can also work through iPhone cases, so you probably don’t need to worry about compatibility.
Of course, there are a lot of cases out there and it’s possible that particularly thick versions won’t connect properly, so if you have an oversized case, try to find a way to test your iPhone on a wireless charger model before you buy it.
