Following a publication of a similar report earlier last year, the FCC tested a number of phones and found no issue https://www.fcc.gov/document/rf-exposure-compliance-test-report

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." Electric field or power density never falls off exponentially and in close it does not fall off as 1/r (electric field) or 1/r² (power density). Very close in it plateaus out.
