Apple Elaborates on Potential for iPhone 12 and MagSafe Accessories to Interfere With Implantable Medical Devices

Since the launch of iPhone 12 models in October, Apple has acknowledged that the devices may cause electromagnetic interference with medical devices like pacemakers and defibrillators, but the company has now shared additional information.

Apple added the following paragraph to a related support document today:

Medical devices such as implanted pacemakers and defibrillators might contain sensors that respond to magnets and radios when in close contact. To avoid any potential interactions with these devices, keep your iPhone and MagSafe accessories a safe distance away from your device (more than 6 inches / 15 cm apart or more than 12 inches / 30 cm apart if wirelessly charging). But consult with your physician and your device manufacturer for specific guidelines.

While the support document already mentioned "MagSafe accessories" in the title, Apple has further emphasized that accessories like the MagSafe Charger and MagSafe Duo Charger may also interfere with medical devices:

All MagSafe accessories (each sold separately) also contain magnets—and MagSafe Charger and MagSafe Duo Charger contain radios. These magnets and electromagnetic fields might interfere with medical devices.

Apple continues to state that while all iPhone 12 models contain more magnets than prior iPhone models, they are "not expected to pose a greater risk of magnetic interference to medical devices than prior iPhone models."

Earlier this month, an article in the Heart Rhythm Journal indicated that iPhone 12 models can "potentially inhibit lifesaving therapy in a patient" due to magnetic interference with implantable medical devices. Three doctors in Michigan tested this interaction by holding an iPhone 12 near a patient's implantable cardioverter defibrillator, which immediately went into a "suspended" state for the duration of the test, according to the article.

"We hereby bring an important public health issue concerning the newer generation iPhone 12 which can potentially inhibit lifesaving therapy in a patient particularly while carrying the phone in upper pockets," the doctors wrote. "Medical device manufacturers and implanting physicians should remain vigilant in making patients aware of this significant interaction of the iPhone 12 and other smart wearables with their cardiac implantable electronic devices."

The article in the Heart Rhythm Journal was first surfaced by Brazilian website MacMagazine.

Apple provides more information in the "Important safety information for iPhone" section of the iPhone User Guide.

I know this doesn't affect most people, but the cons of MagSafe on the iPhone 12 series seem to outweigh the pros.

One has never been recommended to carry any device such as a smart phone or anything magnetic in your upper pockets with any chest implanted electronic device. That has always been the case. Just like you don't go through metal detectors or let TSA wand you.

Never thought I’d live to see the day that a major phone manufacturer had to tell people to be careful not to accidentally kill them selves with their phones...

Is just me or is MagSafe getting less and less appealing? Lol

Magnet Gate. LOL.

All this because Apple did not want to switch to USB-C for charging, because they would lose huge revenue from accessories.

Could have been so simple. One USB-C-charger for your phone, tablet and laptop.
