While it was already quite late to move to wireless charging, Apple’s implementation eventually brought in an element that, in truth, should have become the standard in almost all modern wireless charging systems. Like many small but important amenities, Apple used magnets to ensure stability when charging iPhone 12 wirelessly. As impressive as it may be, the iPhone 12 and its associated MagSafe accessories had one side effect that could go unnoticed as long as recently.

Of course, magnets are not without their positive and negative effects. The latter is often associated with other objects and devices that may also be affected by or negatively affected by magnetism. A worst-case scenario can occur when magnets interfere with vital implanted devices, namely pacemakers and defibrillators.
Almost all smartphones emit electromagnetic radiation by their very nature, but something special about the iPhone 12. These are magnets that are specifically designed to hold MagSafe chargers and accessories in place. While Apple insists that the iPhone 12 poses no greater risk of magnetic interference than older iPhones, it has updated its supporting documents to alert users of this.
This update comes after the medical journal published doctors’ observations on how the iPhone 12 could accidentally interfere with rescue therapy with these implanted medical devices. Specifically, they tested how the phone puts the patient’s cardioverter-defibrillator into standby mode by simply being near it. Apple’s updated document now recommends keeping the iPhone at least 6 inches away from pacemakers and the like.
The warning also applies to MagSafe accessories and especially MagSafe chargers. In fact, Apple is extending the recommended safety distance to 12 inches when iPhone 12 charges wirelessly. While most people probably hide or use their iPhones at that distance anyway, this should serve as an important and important warning for those with implanted medical devices that tend to keep their iPhones close to their hearts, literally.
