additional Information

  • Wireless charging of the iPhone uses magnetic induction. The iPhone and the charger must be in direct contact. Magnetic holders, cases, or other objects between iPhone and charger can reduce performance or damage magnetic strips or RFID chips, such as those found on some credit cards, security IDs, passports, and key fobs. If there are sensitive items like these in your case, remove them before charging, or make sure they're not between the charger and the back of the iPhone.
  • If iPhone doesn't charge or charges slowly, and it has a very thick case, metal case, or battery case, remove the case.
  • For example, if the iPhone vibrates due to a notification, the iPhone may shift. This may interrupt the flow of power from the charging mat to the iPhone. If this happens often, turn off the vibration, turn on Do Not Disturb, or use a case to prevent movement.
  • Depending on the charging mat, you may hear small noises while the iPhone is charging.
  • The iPhone can get a little warmer while charging. If the battery gets too warm, the software will stop charging when the iPhone is more than 80% charged to extend the life of the battery. The iPhone will continue to charge as soon as the temperature has dropped. If possible, move your iPhone and charger to a cooler location.
  • The iPhone does not use the wireless charging function when it is connected via USB. When the iPhone is connected to a computer or USB power supply via USB, the iPhone is charged via USB.
