SAN FRANCISCO (KRON) — The iPhone 12 models may interfere with your medical devices.

Apple warned of the magnets inside its iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, and MagSafe accessories which emit electromagnetic fields that can interact with some medical devices that contain sensors.

For example, implanted pacemakers and defibrillators can be impacted when they are too close to these type of magnets as well as radios.

According to, magnets can activate a switch that keep an Implantable Cardioverter Defibrillator from delivering vital signals such as lifesaving shocks.

“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,” said Apple in a Support post published Jan. 23, 2021.

If you purchased an iPhone 12 or MagSafe accessories, Apple recommends keeping them more than 6-12 inches away from your medical device, or to stop using them completely.

Consult your doctor if you have any concerns of interference with your medical devices.
