In a notice posted on Apple’s support page on Saturday, the company expanded on previously released safety information warning users that iPhones contain magnets and radios that emit electromagnetic fields, which “may interfere” with medical devices such as pacemakers and implanted defibrillators.
Saturday’s notice specifically warns users about “the magnets inside” all four iPhone 12 models, as well as MagSafe accessories. Apple (AAPL) notes that the iPhone 12 versions contain more magnets than previous iPhone models, but it also states that they do not pose a greater risk of magnetic interference with medical devices than previous models.
Apple said in the update that medical devices may contain sensors that may react to magnets or radio waves that are nearby. The company recommends keeping iPhones and MagSafe chargers a “safe distance” from medical devices – which it defines as more than 6 inches or 15 inches apart when wireless charging.
When Apple unveiled the iPhone 12 last fall, the company also announced the return of MagSafe – formerly a beloved MacBook feature – for the iPhone. Customers can purchase MagSafe charging stations to wirelessly charge their devices, as well as other magnetic accessories, including cases and wallets that attach to the backs of phones.
Apple did not immediately respond to a request for comment on why it is now expanding safety guidelines. But the Heart Rhythm Journal published a report earlier this month claiming the iPhone 12’s magnets that make it compatible with MagSafe accessories could interfere with an implanted defibrillator.
“Consult with your doctor and the manufacturer of your medical device for information specific to your medical device and whether you need to maintain a safe separation distance between your medical device and the iPhone or any MagSafe accessory,” Apple said in the notice. “Manufacturers often provide recommendations on the safe use of their devices around wireless or magnetic products to avoid possible interference.”
If a customer feels like their iPhone 12 or MagSafe charger is interfering with their medical device, they should stop using them, Apple said.
Another thing iPhone 12 users should be aware of when using MagSafe chargers: Avoid placing credit cards, security badges, passports, or key fobs between your phone and your MagSafe charger, because the magnets could damage the magnetic tapes or RFID chips in these items, Apple cautions. . If you have a phone case that contains such items, be sure to remove them before charging your device wirelessly.
