RF Safe argues that many “anti-radiation” phone cases use misleading marketing (e.g., fabric-swatch tests, vague “FCC tested” claims) and that some designs may cause phones to increase transmit power if they interfere with antennas. The article provides a checklist of red flags (magnets/metal plates, detachable shields, unclear orientation instructions) and emphasizes behavioral steps to reduce RF exposure. It promotes RF Safe’s QuantaCase as a “directional shielding” design intended to reduce exposure on the body-facing side while avoiding signal blockage that could prompt higher power output.

This study tested magnetic fields from tablets, laptops, smartphones, and household/leisure magnets against 13 cardiac implantable electronic device (CIED) models to assess magnet mode activation. It reports that these consumer devices can trigger magnet mode when in close proximity, with median activation distances of 5–6.5 mm for phones/tablets/laptops and mainly contact-level activation for household/leisure magnets. None of the tested devices activated magnet mode at distances of 20 mm or more, and the authors emphasize patient awareness of proximity-related risk.
