Most of your daily activities now include the presence of your phone. Streaming apps to keep you entertained while eating, always on notifications while you’re working, and the list goes on. But have you ever wondered how the close proximity to your phone constantly might impact your health? Is there a way you can check the SAR Value of your phone? And what is this SAR Value? Let’s find out.
In order to understand if something is good for you, there needs to be a standard value to measure it across all devices. This is where the SAR Value comes in. The SAR Value, also known as Specific Absorption Rate, tells you the amount of RF or radio frequency exposure your body can absorb from your phone.
Intrigued? Let’s learn a little more about SAR value before moving on to measuring it.
What Is SAR Value and Why You Should Check It
As mentioned above, the SAR value helps evaluate the radio frequency your phone emits. While you can use the SAR Value when checking for phone radiation levels, it is only considered relevant when talking about the maximum possible RF exposure to your body. This can be attributed to the fact that several outside factors can impact this result.
However, you should still stay vigilant and know the SAR Value of your current mobile device, and ensure it is within the prescribed limits. Let’s get started.
7 Ways to Check Mobile Radiation (SAR Value)
Now that we know what SAR Value is and why it needs to be checked, let us look at all the ways to check the mobile radiation (SAR Value) on your Android and iPhone.
1. Type USSD Code for SAR Value on Phone’s Dialer
One of the easiest and surefire ways of checking the RF exposure for your device is by using your device’s Phone app. Once opened, key in the USSD code for SAR value and either press call or wait for your device to open the relevant information. Follow the below steps to do it.
Step 1: Open the Phone app.
Step 2: Here, use the keypad to dial *#07#.
Step 3: Either press call or wait for your device to respond to the code automatically.
This will immediately open a new window. Now, scroll through this page and check the phone radiation levels for your device.
Step 1: On your iPhone, open the Phone app.
Step 2: Then, dial *#07# and press the call icon.
Step 3: Here, tap on RF Exposure.
Step 4: Scroll down and tap on the SAR values link.
This will open the details regarding your iOS device’s RF exposure values in a separate web browser.

2. Using the Manufacturer’s Website
Certain mobile manufacturers, like Apple, Samsung, Sony, etc., have RF exposure values listed on their websites. All you need to do is locate your device’s model details, go to the relevant mobile manufacturer’s website, and check the listed information.
To find your mobile phone’s model details, you can either check the box it came in or, if available, the back cover of your mobile. You can also open your device’s Settings app and check your phone details listed there.
3. Checking Your Phone’s Box
If you have your smartphone’s box, you’re in luck. Some mobile companies, like Samsung, Apple, ASUS, etc., print information about your device’s phone radiation levels on the box itself. So, go through all the printed information and, usually below your device’s IMEI information, find the Mobile Radiation (SAR Value).

4. Using Your Device’s User Manual
Almost all device’s come with their user manuals. Apart from having information about your phone’s hardware, functions, accessories, etc., it can sometimes contain relevant information regarding your device’s RF exposure value. To check this, go through your device’s user manual and see if it has a section for RF exposure or SAR Value available.
5. Using the FCC Website
Products certified by the Federal Communications Commission (FCC) are assigned an FCC ID for the same. It can usually be found in your phone’s user manual. This FCC ID can then be used to check your phone’s radiation levels through FCC’s official website. Here’s how.
Step 1: Open FCC’s website using any web browser.
Step 2: Then, enter the first three or five characters of your phone’s FCC ID in the first box.
Step 3: Now, enter the remaining characters of the FCC ID in the second box.
Step 4: Once done, hit the search button.
Now, the FCC’s website will scan its database and give you the SAR Value for the product associated with the entered FCC ID.
6. Using Your Device’s Settings
Besides using a USSD code to check the SAR value, you can also use your phone’s Settings menu to get the relevant information regarding the SAR value. Follow the below steps to do it.
Note: We’re using a Samsung Galaxy device for demonstration. The option to access the RF exposure for your Android device might differ.
Step 1: Open Settings and scroll down.
Step 2: Here, tap on About phone.
Step 3: Then, tap on Legal information.
Step 4: Tap on Safety information.
Now, scroll through the information mentioned and locate the RF exposure section. Then, check your phone’s radiation levels.
Step 1: Open Settings and tap on General.
Step 2: Scroll down and tap on ‘Legal & Regulatory’.
Step 3: Tap on RF Exposure.
Step 4: Locate the SAR values link and tap on it.
This will open the page in a separate web browser, giving detailed information about your iOS device’s current radiation levels.
7. Doing a Google Search
While a Google search might not yield the most accurate results, it can, under certain circumstances, help you figure out the SAR value of, say, iPhone 14 or any other device model. Ensure you specifically mention the device details for accurate results. Follow the below steps to do it.
Step 1: Open Google on any web browser.
Step 2: Now, in the search bar, type your search query and press enter.
Step 3: Then, click on the relevant link to check the SAR value for that device model.
However, ensure to double-check this result with at least one official source, as Google search results can be outdated or inaccurate for certain devices.
FAQs for Checking Your Phone’s SAR Value
The FCC’s prescribed limit for safe exposure is set at the SAR level of 1.6 watts per kilogram (1.6 W/kg).
While there are certain mobile apps available that can help you check the SAR value of your device, we don’t recommend using them. This is because certain apps might require access to sensitive device information to check the SAR Value-related information. This can ultimately put your device’s security at risk.
