The 2 Minute Update looks at an important question: Can cell phone magnets interfere with implanted medical devices?
3 Electrophysiology physicians noticed that wireless charging functions have caused manufacturers to put powerful magnets into cell phones, so they set up an experiment, placing an iPhone 12 directly over an implanted ICD while monitoring the ICD.
They found that iPhone's magnetic field suspended the ICD functions until the phone was removed. They repeated the experiment multiple times, with the same result. The result was reproduced multiple times.

Granted, this is only one combination of cell phone and medical device. But many new cell phones allow for wireless charging, so it seems likely that those phones will also have similar concerns.
Apple even addresses this on their website, cautioning patients to keep at least 6 inches between their iPhone and medical devices, or 12 inches during wireless during wireless charging. They then seem to punt this problem to everyone else, advising patients to consult with physicians and medical device manufacturers. It seems that even though they sell the phone, they want everyone else to accept responsibility for any problems that may arise.

And what about other medical devices, such as pain medication pumps or gastric pacemakers, that are typically located closer to pockets people more commonly place cell phones in?
Please, if you see patients with pacemakers or ICDs placing cell phones near those devices, warn them of this danger. And you may need to think twice before buying a new cell phone for parents or grandparents with medical devices, lest they think you are trying to kill them!
