About the magnets inside iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, and MagSafe accessories


iPhone contains magnets as well as components and radios that emit electromagnetic fields. These magnets and electromagnetic fields might interfere with medical devices, such as pacemakers and defibrillators. 

Though all iPhone 12 models contain more magnets than prior iPhone models, they're not expected to pose a greater risk of magnetic interference to medical devices than prior iPhone models.

Consult your physician and medical device manufacturer for information specific to your medical device and whether you need to maintain a safe distance of separation between your medical device and iPhone. There are many types of medical devices, and manufacturers often provide recommendations on the safe use of their devices around wireless or magnetic products to prevent possible interference. If you suspect iPhone is interfering with your medical device, stop using your iPhone.

We provide more information on medical device interference at Important safety information for iPhone in the iPhone User Guide.
