IPhones could interfere with medical devices such as pacemakers, according to Apple.
The Cupertino, California-based technology company warned users, iPhones contained magnets and radios that emit electromagnetic fields, which “may interfere” with medical devices such as implanted pacemakers and defibrillators, according to an update on Apple’s support page Saturday.
Apple specifically warned users about “the magnets inside” all four iPhone 12 models, as well as MagSafe accessories, per CNN.
IPhone 12 versions contain more magnets than earlier iPhone models, but did not pose a greater risk of magnetic interference with medical devices than earlier models, according to the company.
Medical devices that can contain sensors might react to magnets or radio waves in close proximity.
Apple recommended keeping iPhones and MagSafe chargers a “safe distance” – more than six inches apart, or 15 inches apart when wirelessly charging – from medical devices.
“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 or any MagSafe accessories,” Apple said. “Manufacturers often provide recommendations on the safe use of their devices around wireless or magnetic products to prevent possible interference.”
Apple added, customers who think their iPhone or MagSafe charger was interfering with their medical device should stop using the phone or charger.
MagSafe charging docks allow users to wirelessly charge their devices, and other magnetic accessories (e.g. cases, wallets) that attach to the back of the phones. Apple announced the return of MagSafe last fall when it unveiled the iPhone 12.
The Heart Rhythm Journal released a report earlier this month claiming iPhone 12 magnets that make the device compatible with MagSafe accessories could interfere with an implanted defibrillator.
Apple did not immediately respond to CNN’s request for comment.
Apple also warned iPhone 12 users employing MagSafe chargers that magnetic stripes on credit cards, security badges, passports, etc., could be damaged. It said such items should not be placed between the phone and charger.
Users with phone cases that hold items such as credit cards should remove them before wirelessly charging the device.
