iPhones are compatible with Qi-certified wireless chargers. Note that only iPhone 8 and later has wireless charging. Here are other iPhones with wireless charging: iPhone X, iPhone 11, iPhone SE 2nd/3rd generation, iPhone 12, iPhone 13, and iPhone 14.
Typically, the best charging location is in the center of the wireless charger. If you decide to switch back to wired charging, check out our guides for cleaning your Lightning port and cleaning your Lightning cable.
Additionally, the magnetic induction can potentially damage magnetic strips and RFID chips. Remove any objects with these from your iPhone before using wireless charging. Even the case on your iPhone can prevent charging! Try removing it and trying to charge again.
If you switch back to USB charging, see our guide for tips on charging your iPhone.
