> PACEMAKER WARNING

Apple Watch contains tech to detect heart problems, but the magnets and electromagnetic fields in iPhone and MagSafe accessories could affect medical devices such as pacemakers and defibrillators. In January a medical journal reported that doctors in Michigan held an iPhone 12 near an implantable cardioverter defibrillator, which immediately went into a “suspended” state. They warned patients not to carry an iPhone in their shirt pocket. In a support note (support.apple.com/en-us/HT211900), Apple says “to avoid any potential interactions with these devices” keep your iPhone and MagSafe accessories more than six inches away, or 12 inches when wirelessly charging. Although “all iPhone 12 models contain more magnets than prior iPhone models,” Apple adds, they shouldn’t pose any greater risk of magnetic interference to medical devices than prior models.
