Any smartphone that’s released on the market has to be tested and fit into the accepted limits of radio frequency (RF) exposure and the iPhone makes no exception. The SAR value represents the rate at which the human body absorbs RF energy. As in most cases there are two scales for these values. In some countries the SAR limit is 1.6 watts per kilogram, when the measurement is averaged over 1 gram of tissue. Others prefer the average the values over 10 grams of tissue and in this case the limit is 2.0 watts per kilogram.
How Is The SAR Value Measured
The tests simulate the iPhone usage at head level and body level. During the test the device’s radios are set to their maximum including cellular, Bluetooth, Wi-Fi and all other antennae that emit radio frequency radiation. When the use against the head is simulated, there is no separation between the device and the human tissue, similar to pressing your iPhone against the ear.
Body measurements simulate the use in the torso area and include a 5mm separation caused by clothing and other similar factors.
2020 iPhone SE SAR Values
Below you can find the maximum SAR values measured for the 2nd generation iPhone SE. Results are available for each band of operation and all available iPhone SE models.
SAR (Over 1g) Limit = 1.6 W/kg (U.S. Standard)
Model A2296: Head = 1.17 W/kg, Body = 1.16 W/kg
Model A2275, A2297, A2298: Head = 1.17 W/kg, Body = 1.20 W/kg
(SAR Over 10g) Limit = 2.0 W/kg (European Standard)
Model A2296: Head = 0.98 W/kg, Body = 0.99 W/kg
Model A2275, A2297, A2298: Head = 0.98 W/kg, Body = 0.99 W/kg
iPHone SE s vs iPhone SE SAR Value Comparison
If we compare the values provided above with the ones recorded by the budget iPhone that was coming in the iPhone 5S chassis we can note that values are similar. However the 2nd gen iPhone SE manages to edge out its predecessor by 0.01 W/kg when it comes to body SAR levels measured by the U.S standard, and by the same value when it comes to the head SAR radiation recorded by the European regulations.
iPhone SE 2 vs All Other iPhone Models Ever Released
Below you can check the SAR Value comparison of the iPhone SE 2nd generation and all other iPhone models ever released.
Notice that the 2020 iPhone SE records the highest SAR Value ever for the body-level measurements recorded over 1 gram of tissue. However, the iPhone 7 and iPhone 8 models remain the highest ever radiating iPhone models ever released by Apple!
