According to the Cellular Telecommunications Industry Association (CTIA), SAR or specific absorption rate is "a way of measuring the quantity of radio frequency (RF) energy that is absorbed by the body." The SAR level listed in our chart represents the maximum SAR level for the phone.
North American Standard. The SAR limit for mobile phones used by the public is 1.6 watts/kilogram (W/kg) averaged over one gram of body tissue.
European Standard. The SAR limit for mobile phones used by the public is 2.0 watts/kilogram (W/kg) averaged over ten grams of body tissue.
In order to compare relative radiation of different mobile phones, you can only compare phones using the same measurement.
Many questions are sent to us asking why our results differ from CNET on some model phones. CNET only publishes the SAR rating of the phone in the head position, we publish the HIGHEST SAR rating of the phone regardless of the position. We believe this is the proper rating.
