Colors make differences within the same measurement easy to see. They do not label a phone safe or unsafe. US values use 1 g of tissue and the 1.6 W/kg limit; EU values use 10 g and 2 W/kg, so don't mix them. What SAR tells you.
Questions and answers
Which has lower head SAR, the Apple iPhone 8 Plus or the Apple iPhone 6 Plus?
The Apple iPhone 8 Plus lists the lower head sar, cellular only (us): 1.09 W/kg vs 1.19 W/kg for the Apple iPhone 6 Plus (8% lower). Values are reported maximums from FCC filings as listed in the RF Safe dataset, in W/kg averaged over 1 gram of tissue.
Which has lower body SAR, the Apple iPhone 8 Plus or the Apple iPhone 6 Plus?
The Apple iPhone 8 Plus lists the lower body sar, cellular only (us): 1.09 W/kg vs 1.19 W/kg for the Apple iPhone 6 Plus (8% lower). Values are reported maximums from FCC filings as listed in the RF Safe dataset, in W/kg averaged over 1 gram of tissue.
Which has lower hotspot SAR (Wi-Fi + cellular), the Apple iPhone 8 Plus or the Apple iPhone 6 Plus?
Both list the same hotspot sar, wi-fi + cellular (us): 1.59 W/kg. Values are reported maximums from FCC filings as listed in the RF Safe dataset, in W/kg averaged over 1 gram of tissue.
What is the highest reported SAR value for each phone?
Across the six US measurements, the Apple iPhone 8 Plus's highest listed value is 1.59 W/kg and the Apple iPhone 6 Plus's is 1.59 W/kg. The FCC limit for the head and body is 1.6 W/kg averaged over 1 gram. Wi-Fi + cellular values are simultaneous-transmission sums and are evaluated differently, so read each row on its own.
Does a lower SAR mean a phone is safer?
No. SAR is a lab compliance measurement taken at maximum power. Everyday exposure depends on signal strength, distance from the body and which radios are active. Use SAR to compare phones, not as a health score.
Where do these numbers come from?
From the RF Safe SAR dataset, compiled from FCC equipment authorization filings (FCC ID BCG-E3160A and BCGE2817A). Nothing on this page is estimated.
