There are a number of Qi wireless chargers that are advertised for the iPhone 8 and iPhone X that hold the phone on by a magnet. From what I have heard, Apple said that any Qi wireless charger will work with iPhone 8 and iPhone X. Is there any official guidance regarding whether or not the magnetic Qi wireless chargers could harm the iPhone. Because there has been none, I am led to believe that it is safe to use.
Is there (official or otherwise) reason to believe that magnetic Qi chargers could harm iPhone 8 or iPhone X?
