The new iPhone 12 has many good features, but one could be dangerous for people with pacemakers or defibrillators.
Apple recently updated its support documents to say that its magnetic charging system can cause electromagnetic interference, according to Komando.com.
Its magnetic charging system is called MagSafe and it uses a ring of magnets on the phone's back to snap onto a wireless charger. The magnets keep the charger in the right position.
However, the magnets can interfere with medical devices if they come into close contact.
Heart Rhythm Journal reported that doctors in Michigan held an iPhone 12 near an implanted cardioverter defibrillator. The defibrillator entered a suspended state, a sign of interference that could mean the medical device was no longer pumping blood through the body.
Both doctors and Apple advise keeping the iPhone and MagSafe accessories at least six inches, and preferably 12 inches away from your device.
