Apple has updated its support documentation for the iPhone 12 magnetic charging system to confirm that MagSafe devices can cause electromagnetic interference with devices such as pacemakers and defibrillators.

Since the launch of the iPhone 12 and MagSafe, concerns have been raised that it could interfere with critical medical devices. And they have turned out to be justified. Apple's advice in response is to keep the iPhone 12 at least 6-12 inches away from MagSafe chargers and the latest flagship phones.

The MagSafe system uses a magnetic ring on the back of the iPhone 12 that snaps into place when the Qi wireless charger is placed together. This magnet keeps the charger in place at all times, but can also be removed in an instant.

However, magnets and medical devices do not have a good history. As the updated support document mentions, "Medical devices such as implantable pacemakers and defibrillators may contain sensors that respond to magnets or wireless. To avoid potential interactions with these devices, keep your iPhone and MagSafe accessories at a safe distance from the device (at least 15 cm for wireless charging and 30 cm for wireless charging). However, consult your physician or the device manufacturer for specific guidelines."

Apple also added language emphasizing the fact that the MagSafe accessory also contains a magnet and that the charger itself uses wireless. Both can interfere with medical devices if they get too close.

MacRumors noted that at least one medical article accuses Apple's MagSafe of doing exactly this; its post from the Heart Rhythm Journal claims that the iPhone 12 device "could interfere with patients' life-saving treatment." It states. Apparently, a Michigan doctor placed the iPhone 12 near an implantable defibrillator and it went into a "suspended state."

Obviously, if you are dependent on these types of devices, the last thing you need is for your iPhone to malfunction. Therefore, if you have an iPhone, get professional advice from your doctor and be vigilant. if you suspect that the iPhone 12 or MagSafe is interfering with the daily functioning of your medical device, Apple recommends that you stop using your iPhone and charger The company recommends that the patient discontinue use of the iPhone and the charger.

Despite the potential risk to some patients and other magnet-related issues, it appears that MagSafe is here to stay. in addition to being included in the iPhone 13, Apple is also introducing an upgraded version of the MacBook Air with a similar magnetic charger There are also reports that the company will be releasing a new version of the MacBook Air with a similar magnetic charger. Meanwhile, the upcoming MacBook Pro 16-inch is said to feature an updated version of the classic breakaway MagSafe cable.
