Smartphones have different performance data and accordingly, there is also an indicator that measures the radiation that a smartphone emits to the outside world. This is known as the SAR value.
The specific absorption rate (SAR) is a measure of the rate at which energy in the form of radio waves is absorbed by the human body. During absorption, heat is generated in human tissue. The higher the value, the warmer it gets during a phone call and the more the tissue is stressed. The absorption rate is measured in watts per kilogram (W/kg).
In Europe, the SAR limit according to IEC standards is 2 W/kg, which should not be exceeded, otherwise long-term damage may occur.
SAR Value Samsung Galaxy Note Series
Samsung Galaxy Note 20
- SAR value head: 0.359 W/kg
- SAR value body: 1.366 W/kg
Samsung Galaxy Note 20 Ultra
- SAR value head: 0.315 W/kg
- SAR value body: 1.47 W/kg
Now you know the SAR values for the head and body region for the models Note 20 and Note 20 Ultra.
