  • Apple has updated a support document to make it clearer that iPhone 12 and MagSafe accessories can interact with pacemakers and defibrillators.

Apple has updated a support document (opens in new tab) to make it more clear that iPhone 12 and MagSafe accessories could potentially interact with a person's implanted pacemaker. The same goes for implanted defibrillators, too.

First noted by MacRumors, the support document has gained a new paragraph that warns users that they should keep MagSafe magnets away from any devices they may have implanted.

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.

Apple's text previously said that while magnets are used in MagSafe, it shouldn't be an issue any more than any other phone.

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.

Apple had previously been vague in its stance on whether MagSafe could impact a person's implanted medical device, but this new addition to an existing support document does make things much more clear. However, it's still important to speak to your doctor if you're at all concerned about your particular situation.

This update comes after a report earlier this month noted that MagSafe could be troublesome if placed too close to a particular type of device.
