A radio frequency exposure test finds an iPhone 11 Pro exceeds the FCC's limit
Testing phones from 5 millimeters away from the body may seem close, but for anyone carrying their phone in a pocket, the distance is closer to 2 millimeters. Because wireless power falls off exponentially with distance, what might be a safe amount of RF exposure at 5 millimeters could be much higher at 2 millimeters.They mean to say that you should expect a power about 6 times higher, (5^2 / 2^2). This is rubbish.The square of the distance model is for a pair of points. Phones in pockets at such closed distances are more closely modeled by a pair of infinite planes where the power falls off not at all. The real result will be in between, but very much closer to 1 than 6.
