Apple now recommends that you do not use the iPhone 12 or the MagSafe charger near a pacemaker. According to the Cupertino company, it is not impossible that the magnets integrated into its devices disrupt the operation of cardiac pacemakers and defibrillators. Ultimately, it is advisable not to slip the iPhone 12 into your jacket pocket.

With the iPhone 12, Apple is launching a new wireless charging technology: MagSafe. Inspired by the magnetic charger found on older MacBooks, the MagSafe charger attaches firmly to the back of iPhone thanks to a series of magnets. The manufacturer has indeed slipped powerful magnets in the charger and on the back of its new smartphones.

Unfortunately, this new technology quickly aroused concern among cardiologists. According to a study by Heart Rythm, a medical journal specializing in cardiac arrhythmias, the magnets in iPhone 12 and the MagSafe charger may deactivate pacemakers. For that, it is enough that the magnet is found at a few centimeters from the pacemaker.

Apple asks users with pacemakers to be careful

In response to medical warnings, Apple has updated the iPhone 12 support page. Aware of the risks raised by doctors, the Californian giant recommends no longer approaching the iPhone 12, or its MagSafe accessories, a pacemaker.

“To avoid any potential interaction with these devices, keep a safe distance between your iPhone (and its MagSafe accessories) and your medical device (over 15cm or over 30cm when charging wirelessly)” Apple cautions. De facto, users with a pacemaker are requested to slip their smartphone into their pants pocket rather than their jacket pocket, too close to the heart.

“Although all iPhone 12 models contain more magnets than previous iPhone models, they are not expected to present a greater risk of magnetic interference with these devices” reassures Apple. Nevertheless, the brand concedes that “Medical devices such as implanted pacemakers and defibrillators may contain sensors that react to nearby magnets and transmitters”. Apple recommends that users with a pacemaker contact their doctor. If the cardiac simulator malfunctions, the group advises to stop using the iPhone or the MagSafe charger.
