When the iPhone 12 was launched, Apple introduced a new charging feature called MagSafe (different from the one used in Apple’s older MacBooks). This is a magnetic charging system that magnetically attaches a charging puck to the back of the iPhone. It sounds pretty cool and useful, but some have raised concerns that the magnets could affect implanted medical devices like pacemakers.
In fact, there was even a video uploaded by a doctor who suggested that it could interfere with pacemakers. For those who might be concerned, the FDA has since weighed in with their own assessment after an investigation in which they concluded that the iPhone 12’s MagSafe feature only poses “low risk” to medical implants.
According to Dr. Jeff Shuren, the director of the FDA’s Center for Devices and Radiological Health, “We believe the risk to patients is low and the agency is not aware of any adverse events associated with this issue at this time.” However, while he states the risk is low, he also advises that those with medically implanted devices should still be aware about the potential risks involved and maybe speak to their health care providers on how to best use these devices.
Apple themselves had previously posted their own support document where they advise users with medical implants to keep the iPhone at least 6-12 inches away from their implants.
