Did you know that Apple’s iPhone 12 models come with a feature that could pose a risk to some users? The MagSafe magnets, designed for easy accessory attachment, have a potential interference issue with medical devices like pacemakers and defibrillators.

According to Apple, these magnets can disrupt the functioning of such devices if held too close.

While this risk was prominently highlighted with the iPhone 12, it raises a broader question about the safety of smartphones and similar devices for individuals with medical implants. As tech continues to advance, staying informed about these potential hazards is essential.
