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 11 or the Apple iPhone 7?

The Apple iPhone 7 lists the lower head sar, cellular only (us): 1.10 W/kg vs 1.14 W/kg for the Apple iPhone 11 (4% 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 11 or the Apple iPhone 7?

Both list the same body sar, cellular only (us): 1.14 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.

Which has lower hotspot SAR (Wi-Fi + cellular), the Apple iPhone 11 or the Apple iPhone 7?

The Apple iPhone 7 lists the lower hotspot sar, wi-fi + cellular (us): 1.16 W/kg vs 1.52 W/kg for the Apple iPhone 11 (24% lower). 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 11's highest listed value is 1.52 W/kg and the Apple iPhone 7's is 1.56 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-E3309A and BCG-E3085A). Nothing on this page is estimated.
