How To Check SAR Value: What It Is & Why It Matters in 2024

SAR (Specific Absorption Rate) measures the amount of radiofrequency (RF) energy absorbed by the body when using a mobile phone. It is important because high SAR levels may pose health risks if exposure exceeds safety limits.


📌 What Is SAR Value?

  • SAR is measured in watts per kilogram (W/kg).
  • It indicates how much radiation your body absorbs from a mobile device.
  • Governments set SAR limits to ensure safety:
    • USA (FCC limit): 1.6 W/kg (measured over 1g of tissue)
    • EU (ICNIRP limit): 2.0 W/kg (measured over 10g of tissue)

📋 How to Check SAR Value of Your Phone

1️⃣ Check SAR Value Using USSD Code (Works on Most Phones)

📲 Dial: *#07# on your phone.

  • If supported, it will display the SAR values for head & body.
  • If not, it may redirect you to your phone’s regulatory information page.

2️⃣ Check in Your Phone’s Settings

📱 Steps (Varies by Brand):

  1. Go to "Settings"
  2. Search for "SAR" or "About Phone"
  3. Tap on "Regulatory Information" to find SAR values

3️⃣ Check SAR on the Manufacturer’s Website

Most smartphone brands list SAR values on their official websites.

  • Visit the official website of your phone brand (e.g., Samsung, Apple, Xiaomi).
  • Search for "SAR value + [Your Phone Model]".

🔗 Example: Apple SAR values pagehttps://www.apple.com/legal/rfexposure/


4️⃣ Check SAR Value on Official Regulatory Websites

Many countries have online databases to check SAR values:

How to Use FCC ID Search:

  1. Find your phone’s FCC ID (usually in "About Phone" or on the device box).
  2. Enter the FCC ID on the FCC website to check its SAR value.

📌 Why Does SAR Value Matter?

Although no conclusive evidence proves that SAR affects health, excessive exposure to radiation could have potential risks.

⚠️ High SAR Risks (Debated)

🔴 May cause heat-related tissue damage
🔴 Possible long-term health concerns (still under study)
🔴 Could lead to headaches or discomfort after long usage

✅ How to Reduce SAR Exposure?

✔️ Use wired or Bluetooth earphones instead of placing the phone directly on your ear.
✔️ Enable speakerphone mode during calls.
✔️ Keep the phone away from your body (don’t carry it in your pocket for long).
✔️ Use your phone in areas with strong signals (low signal = higher radiation).
✔️ Avoid long calls or switch sides to minimize exposure.


📌 Summary

  • SAR value indicates radiation absorption from mobile devices.
  • You can check SAR using *#07#, phone settings, or official websites.
  • Lower SAR is better, but exposure can be reduced with simple precautions.
