It is normal for your device(s) to warm up slightly during wireless charging, but abnormal if it gets too hot.

To prevent overheating when charging, please avoid:

 ● Using a protective case thicker than 2 mm.

 ● Placing metal accessories, credit cards, or pop sockets between your device(s) and the charger.

If overheating occurs, the charger will enter overheat-protection mode and pause charging. If this happens, please:

 ● Disconnect the device(s) from the charger, take off any protective case, and let the device(s) and charger cool down.

 ● Close apps that are not being used on your devices.

 ● When your device(s) and the charger have cooled down, resume charging.

Please check:

 ● Your phone is an iPhone with MagSafe (iPhone 12 series or later).

 ● Use the included charging cable.

 ● Your power adapter or USB port outputs at least 20W. 

 ● Your protective case is less than 2mm thick.

 ● There are no metal accessories, credit cards, or pop sockets between your phone and the charger.

Additional information about wireless charging speeds:

 ● Wireless charging is not as fast as wired charging.

 ● Limiting the number of applications you have open simultaneously on your phone will improve charging speed.

 ● High temperatures will reduce charging speed and restrict power, which is something that happens during wireless charging.

 ● When your iPhone stops charging at 80%, it may be due to "Optimized Battery Charging". Please check whether turning it off helps. Click Settings > Battery > Battery Health > Turn off "Optimized Battery Charging". If you haven't enabled "Optimized Battery Charging", the issue is mostly caused by the iOS upgrade. Please upgrade or wait for the next system upgrade.

Please check:

 ● Your phone is an iPhone with MagSafe (iPhone 12 series or later).
