Issued a new warning for millions of iPhone 12 users.

Apple’s iPhone 12 lineup continues to break sales records. But now, a major new study has warned that phones pose a huge health risk. Here’s what you need to know.

MORE FROM FORBESApple has confirmed that the iPhone 12 Range can interfere with pacemakers.

This week, the Journal of the American Heart Association (JAHA) published a new study on the potential health risks of MagSafe, the magnetic charging system Apple built into all iPhone 12 models. JAHA concluded that the iPhone 12 “has The potential to inhibit life-saving therapy.”

The problem stems from Magsafe’s potential to cause electromagnetic interference with implantable electronic devices (CIEDs), including pacemakers and defibrillators. JAHA said tests found that CEIDs can only be disturbed by magnetic fields. 10 G [gauss] While “The magnetic field strength of iPhone 12 Pro Max can be over 50 G when in direct contact.”

“Our case study has several clinical implications,” explains JAHA. “People tend to put their smartphones in their pockets over devices that might be close to CIED. This can lead to asynchronous pacing. ranus or disabling anti-tachycardia treatment.”

JAHA’s findings are consistent with research conducted by the Heart Rhythm Journal in January. It warns that MagSafe magnets during iPhone 12 can “suppress life-saving therapy in patients,” and recommends that “to avoid potential interactions with these devices, keep iPhone and MagSafe accessories away from you. safely [CIED] devices (more than 6 inches / 15 cm apart or more than 12 inches / 30 cm apart if charging wirelessly)”

Apple responded to those findings with supporting documentation recognizing the potential for interference. But assessing the risk, he said, “While every iPhone 12 has more magnets than previous iPhones, it is not expected to be at risk of medical magnetic interference. more devices than any previous iPhone.”

But JAHA research, while searching for some CEID brands, is more sensitive than others. But to dispute Apple’s claims in particular:

“Apple Inc has a recommendation indicating that the newer iPhone 12 models are not at increased risk of magnetic interference compared to older iPhones. However, our study points out otherwise. This is because the magnetic response is demonstrated in 3/3 cases in vivo. Compared to the older iPhone 6, a study conducted by Lacour et al found no cases of magnetic response in a sample size of 148 patients.”

More than a million pacemakers worldwide every year, 200,000 of them in the United States and “These numbers are expected to increase” (source), the backup said. APSF (Aesthesia Patient Safety Foundation) states, “Atrial fibrillation affects approximately 14.4 million people in the United States, and one has Approximately 40,700 deaths per year.”

“In summary, this report highlights the importance of public awareness,” the JAHA said. “Patients should consult with a cardiac rhythm specialist about specific recommendations for smartphones and CIED.”

It remains to be seen whether Apple will update the MagSafe warning on its website in light of this new information. And with leaks claiming that MagSafe magnets will be “stronger” in the upcoming iPhone 13, questions about convenient charging technology seem to be rising.

I have contacted Apple and will update this article when/if I receive a response.
