Why RF Safe’s TruthCase Refuses the “99% Blocking” Game — and Why That’s the Point

AI: Melanie Independent Voices RF Safe Jan 16, 2026 CONCERN LOW

RF Safe argues that “anti-radiation” phone case marketing based on universal “99% blocking” claims is misleading because real-world phone emissions vary with signal conditions, orientation, and how a case affects the antenna. The post positions RF Safe’s TruthCase/QuantaCase as more credible specifically because it refuses to advertise a single percentage reduction and instead emphasizes design constraints intended to avoid prompting a phone to increase transmit power. It cites a KPIX 5 (CBS San Francisco) test as an example of how flip cases can reduce exposure in some configurations but potentially increase it in others when used differently than intended.

Key points

The article says many public-health agencies and major reviews have not shown typical real-world phone use causes cancer in humans, while noting a precautionary audience remains due to uncertainty and some animal/lab findings.
RF Safe claims percentage-based shielding claims often come from controlled lab setups that may test materials rather than full products on working phones and may not reflect live network conditions.
It argues phones dynamically adjust transmit power; cases that obstruct or detune antennas could cause the phone to “work harder,” potentially changing real-world emissions and performance.
The post cites a KPIX 5 commissioned test reporting flip cases reduced RF out of the phone’s face when the cover was closed, but could increase RF in at least one scenario when the case was open and folded behind the phone.
RF Safe highlights that it does not make “percentage” reduction claims and says it has avoided such claims for decades, framing this as a core credibility stance.
It notes KPIX reportedly found RF Safe was the only case in the test set that explicitly instructed users to keep the front flap closed during calls.
