FDA Says Risk of MagSafe Interference With Pacemakers is Low

Earlier this year, three doctors in Michigan found that iPhone 12 models can "potentially inhibit lifesaving therapy in a patient" due to the MagSafe system causing magnetic interference with implantable medical devices, like pacemakers.

Following its own testing, the U.S. Food and Drug Administration this week announced that while certain newer cell phones, smart watches, and other electronics with magnets may temporarily affect the normal operation of implanted medical devices, such as pacemakers and implantable defibrillators, the risk to patients is "low." The FDA added it is "not aware of any adverse events associated with this issue at this time."

However, the FDA has advised patients with implanted medical devices to consider taking the following precautions:

  • Keeping consumer electronics, such as certain cell phones and smart watches, six inches away from implanted medical devices.

  • Refraining from carrying consumer electronics in a pocket over the medical device.

  • Talking to your health care provider if you have questions regarding magnets in consumer electronics and implanted medical devices.

The FDA's precautions are in line with guidelines shared by Apple, which advises customers to keep their iPhone and MagSafe accessories more than six inches away from their medical device, or more than 12 inches apart if the iPhone is being wirelessly charged. Apple says to consult with a physician and the device manufacturer for specific guidelines.

The FDA's announcement was highlighted earlier by 9to5Mac.

In fact it is all about some general knowledge about yourself and your health status. One might place a magnetic iPhone in the pocket of their jacket. Knowing there is a pacemaker right there behind that pocket might be a reason, not to do that, instead of declaring that magnet as "dangerous". So, a wise decision of the FDA.

Anyone thinking about to declare hazelnuts as dangerous, because there are quite some allergic reactions?
The FDA are right to make the general public aware of any potential risks. My father had a pacemaker, he also had dementia so he wouldn’t remember any safety advice he was given.

While I don't have a pacemaker, anything with magnets should cause caution around people with pacemakers. This is another device to add to the list.

As someone with a pacemaker, let me clarify:

"Interfere" means anything that causes anomalous/undesired behavior, however petty. Placing a magnet on a pacemaker will override normal operation, flipping to a default pacing rate (60 BPM). This is intentional, so medical personnel can force the device to a stable & reasonable state if anything is awry [insert personal anecdote]. This isn't bad, it's just little more than an annoyance. Simply removing the magnet will restore normal device operation.

Jesus CHRIST, I’m more worried about that 12 Pro dangling upside-down from a MagSafe charger than I am about these potential risks.
No need to worry, it's not even a real 12 Pro. No LiDAR sensor in that camera array!

Yes, absolutely agree. Advice about potential danger, so anyone can act accordingly or be assisted like your father.
Unfortunately nowadays far to often a product gets kind of doomed because of potential risks, instead of just "pay attention on the possible risks".

Well the FDA are a bunch of technicians. They know technical stuff. Unlike EU lawmakers who have no clue about anything.
