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 Samsung Galaxy A56 or the Samsung Galaxy A55?

The Samsung Galaxy A56 lists the lower head sar, cellular only (us): 0.87 W/kg vs 0.91 W/kg for the Samsung Galaxy A55 (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 Samsung Galaxy A56 or the Samsung Galaxy A55?

The Samsung Galaxy A55 lists the lower body sar, cellular only (us): 0.65 W/kg vs 0.88 W/kg for the Samsung Galaxy A56 (26% 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 Samsung Galaxy A56 or the Samsung Galaxy A55?

The Samsung Galaxy A55 lists the lower hotspot sar, wi-fi + cellular (us): 1.56 W/kg vs 1.60 W/kg for the Samsung Galaxy A56 (3% 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 Samsung Galaxy A56's highest listed value is 1.60 W/kg and the Samsung Galaxy A55'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 A3LSMA566E and A3LSMA556E). Nothing on this page is estimated.
