Always more sophisticated, the iPhone 12 marks a break with the previous models and this is not necessarily good news for all users. The site MacRumors notes that Apple recently updated the user guide for its smartphone to alert you to the risk of interference with medical devices.

“The iPhone contains magnets as well as components and radios that emit electromagnetic fields. These magnets and electromagnetic fields can interfere with medical devices such as pacemakers and defibrillators ”, can we read on the site of the American giant.

An “About” page allows you to learn more about interference caused by its iPhone 12, 12 mini, 12 Pro and 12 Pro Max as well as MagSafe accessories.

Like smartphones, the latter contain magnets while the MagSafe and MagSafe Duo chargers contain transmitters. According to Apple, these “Magnets and these electromagnetic fields are liable to interfere with the proper functioning of medical devices”.

What should people with pacemakers do?

The Cupertino company recommends that people concerned keep a distance of at least 15 cm or 30 cm in case of wireless charging between their medical device and its products (iPhone 12 and MagSafe accessories).

However, Apple does not want to be alarmist and believes that “Although all iPhone 12 models contain more magnets” than previous models, these new devices “Are not believed to present a greater risk of magnetic interference” with these medical implants. However, it is also advisable to consult your doctor or the manufacturer of the medical device for specific instructions.

Appeared in 2006 on the MacBook Pro, MagSafe technology made a noticeable return in October 2020 on all iPhone 12 models. Brought up to date, Cupertino’s magnetic connector uses a system based on magnets that can pose problem for people with pacemakers.

Apple’s communication on this subject comes a few weeks after the publication of a study indicating that the iPhone 12’s MagSafe magnets could deactivate a medical device.

Published by the medical journal Heart Rhythm, this study conducted by cardiologists highlighted the fact that an iPhone 12 suspends the activity of a Medtronic cardiac defibrillator when it is placed at the level of the chest. This phenomenon has been observed several times, by placing the smartphone in different positions.

For now, this is not enough to prove that this new iPhone is more dangerous than other smartphones.

The apple brand is not the only one concerned, as many devices are liable to disrupt the functioning of cardiac pacemakers. Apple preferred to limit the risks and take the lead in confirming this problem.
