Visualizes head SAR (1.18 W/kg = 74%) against the FCC ceiling of 1.6 W/kg.
Context
What this number means
At 1.18 W/kg, the Galaxy S22 Ultra's head SAR is in the typical range for current smartphones — about 74% of the FCC's 1.6 W/kg ceiling. Most flagship iPhones, Galaxies, and Pixels cluster in this 0.80–1.20 W/kg band.
Remember: SAR is a peak-power compliance test against a tissue-mimicking phantom. Your real exposure depends on signal strength, distance from the phone, and call duration. To model actual exposure at distance, try the RADIHALT EMF Calculator.

Practical Steps
Reduce real exposure from your Galaxy S22 Ultra
Use speakerphone or headphones
SAR is measured against the head. Keeping the phone a few inches away during calls reduces exposure substantially due to the inverse-square law.
Avoid weak-signal use
Phones boost transmit power dramatically when signal is weak. Wait for stronger signal or use Wi-Fi calling indoors when cellular bars are low.
Don't carry against skin
Body SAR is tested with a 10–15 mm spacer. Carrying the phone directly in a pocket against your skin can push real-world body exposure above the tested value.
Shield where it matters
A copper-nickel Faraday fabric (like the RADIHALT blanket) attenuates RF energy from your lap or work surface during long sessions.
Galaxy S22 Ultra SAR FAQ
Frequently asked questions
What is the SAR value of the Galaxy S22 Ultra?
The Galaxy S22 Ultra has a head SAR of 1.18 W/kg and a body SAR of 0.98 W/kg per FCC testing (FCC ID A3LSMS908U). Both values are measured against the U.S. FCC limit of 1.6 W/kg averaged over 1 gram of tissue.
Is the Galaxy S22 Ultra safe to use?
The Galaxy S22 Ultra is FCC-certified, meaning it tested below the 1.6 W/kg legal limit for both head and body exposure. The FCC limit includes a roughly 50× safety margin below any observed thermal biological effect. We don't make health claims either direction — we present the FCC data so you can decide what's right for you.
How does the Galaxy S22 Ultra compare to other phones?
At 1.18 W/kg head SAR, the Galaxy S22 Ultra sits at 74% of the FCC limit. Modern flagship phones typically report head SAR values between 0.80 and 1.30 W/kg.
How can I reduce my Galaxy S22 Ultra's radiation exposure?
Use speakerphone or wired/Bluetooth headphones during calls, don't carry it directly against skin in pockets, and use it where signal is strong (phones boost transmit power dramatically in weak-signal areas). Try our EMF calculator to model how distance changes your real exposure.
