With the iPhone 12, Apple introduced MagSafe as a way to charge the phone. It uses a set of magnets around a charging coil to connect the iPhone to the power adapter. MagSafe can also be used to attach accessories such as wallets or car mounts.
However, there’s long been an issue with magnets and medical devices that a person has implanted in their body. Heart Rhythm Journal recently posted the results of a study that showed that the iPhone 12’s MagSafe disrupted a patient’s implanted defibrillator.
