"Apple warns against keeping iPhone too close to chest for safety"

Apple has warned users with medical devices to keep their consumer-electronic products at a safe distance, as most devices contain magnets or components that emit electromagnetic fields that can interfere with certain medical devices. Apple recommends keeping the product more than 6 inches (or 15 cm) apart or more than 12 inches (or 30 cm) apart if wirelessly charging. The company also advises users to consult with their physician and medical-device manufacturer for specific guidelines and to stop using their Apple product if they suspect it is interfering with their medical device.
