So, let’s take a look at the numbers and see if the Cupertino-based tech company has managed to perform a better job than last year, when it launched the highest radiating iPhones ever manufactured, the iPhone 7 and iPhone 7 Plus. Why are the Radio Frequency exposure values important? RF Exposure is measured in SAR (Specific Absorption Rate) units, which show how much electromagnetic radiation the user’s body absorbs when using the iPhone’s antennas at maximum capacity!
iPhone 8 & iPhone 8 Plus SAR Values
The RF Exposure values presented below are measured according to the U.S. standards as well as the European regulations. The American scale analyzes radiation absorbed over 1gr of tissue, while the E.U. one averages values over 10 grams.
Fact: The lower the values the lower is the radiation that the user’s body or head is exposed to!
Important: Depending on the cellular network compatibility, Apple sells three distinct models of iPhone 8 and iPhone 8 Plus devices. You can find out your model number by browsing the Settings app for General -> About.
iPhone 8 (A1863 / A1906 / A1905)
SAR (Over 1gr) – Body: 1.13 / 1.14 / 1.17 | Head: 1.20 / 1.17 / 1.19 – Limit: 1.6 W/kg
SAR (Over 10gr) – Body : 1.36 / 1.36 / 1.36 | Head: 1.35 / 1.36 / 1.32 – Limit: 2.0 W/kg
iPhone 8 Plus (A1864, A1898 / A1897)
SAR (Over 1gr) – Body: 1.15 / 1.19 / 1.19 | Head: 1.15 / 1.19 / 1.19 – Limit: 1.6 W/kg
SAR (Over 10gr) – Body : 0.99 / 0.99 / 0.99 | Head: 0.94 / 0.97 / 0.99 – Limit: 2.0 W/kg
iPhone 8 & 8 Plus SAR Value Comparison vs Predecessors
Check out the diagram that I created nearby to make yourself a better idea how the 2017 flagships compare to all their predecessors. Notice that the iPhone 7 remains the highest radiating smartphone ever created by Apple. The iPhone 8 RF Exposure values are marginally smaller when compared to the iPhone 7 range. Significant differences can be noticed in the iPhone 8 Plus measurements. The Head SAR values are significantly smaller when using the 10gr scale.
Conclusion: Although the iPhone 8 range is less radiating than the iPhone 7 lineup Apple still has a long way to go until it reaches the impressive values measured on their main Android competitors. The Samsung Galaxy S8 and S8+ flagships measure:
Samsung Galaxy S8
SAR (Over 1gr) – Body: 0.75 | Head: 0.38 – Limit: 1.6 W/kg
SAR (Over 10gr) – Body : 1.27 | Head: 0.32 – Limit: 2.0 W/kg
Samsung Galaxy S8+
SAR (Over 1gr) – Body: 0.97 | Head: 0.41 – Limit: 1.6 W/kg
SAR (Over 10gr) – Body : 1.00 | Head: 0.27 – Limit: 2.0 W/kg
