Apple is saying that its smartphones could interfere with medical devices, including pacemakers in a significant warning to its customers.
An artificial cardiac pacemaker is a medical device that uses electrical impulses to contract the heart muscles and therefore pump blood.
In a notice published on Apple’s support page, the company expanded upon previously issued safety information, warning users that iPhones contain magnets and radios that emit electromagnetic fields, both of which “may interfere” with medical devices such as implanted pacemakers and defibrillators.
Keep them at a safe distance
The latest notice specifically warns users about “the magnets inside” all four iPhone 12 models, as well as MagSafe accessories. Apple notes that iPhone 12 versions contain more magnets than prior iPhone models, but it also said they don’t pose a greater risk of magnetic interference with medical devices than earlier models.
Apple said in the update that medical devices can contain sensors that may react to magnets or radio waves that come in close proximity. The company recommends keeping iPhones and MagSafe chargers a “safe distance” away from medical devices. The company defines the safe distance as more than 6 inches apart, or 15 inches apart when wirelessly charging.
When Apple unveiled the iPhone 12 last year, the company also announced the return of MagSafe, formerly a beloved MacBook feature, for the iPhone. Customers can buy MagSafe charging docks to wirelessly juice-up their devices, and other magnetic accessories including cases and wallets that attach to the back of the phones.
Health experts have long cautioned not to use or hold cellphones too close to implanted medical devices for example, warning people not to store them in shirt pockets.
“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 in the notice. “Manufacturers often provide recommendations on the safe use of their devices around wireless or magnetic products to prevent 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 is that avoid placing credit cards, security badges or passports between your phone and your MagSafe charger, as the magnets might damage magnetic strips or RFID chips in these items, Apple warns. If you have a phone case that holds such items, be sure to remove them before wirelessly charging your device.
