Most of your daily activities are now in the presence of your phone. Stream apps that keep you entertained while you eat, stay informed while you’re working, and the list goes on. But have you ever wondered how constantly keeping your phone nearby can affect your health? Is there any way you can check your phone’s SAR Value? And what is this SAR Value? Let’s find out together.
To understand whether something is good for you, it is necessary to have a standard value to measure that across all devices. This is where the SAR Value comes into play. The SAR value, also known as the Specific Absorption Rate, tells you how much radio frequency or RF exposure your body can absorb from your phone.
Have a plot? Let’s learn a little more about the SAR value before moving on to measuring it.

What is the SAR value and why should you test it?
As mentioned above, the SAR value helps to assess the radio frequency your phone emits. While you can use the SAR Value when checking your phone’s radiation levels, it is only considered appropriate when it comes to the maximum possible RF exposure to your body. This could be because a number of external factors could have influenced this result.
However, you should still be vigilant and know the SAR Value of your current mobile device and make sure it is within regulatory limits. Start.
7 ways to test mobile radiation (SAR Value)
Now that we know what the SAR Value is and why it is necessary to check it, let’s take a look at all the ways to check mobile radiation (SAR Value) on your Android and iPhone.
1. Enter USSD Code for SAR Value on Phone Dialer
One of the easiest and surest ways to test your device’s RF exposure is to use the Phone app on your device. Once opened, enter the USSD code for the SAR value and press call or wait for your device to open the relevant information. Follow the steps below to do that.
On Android
Step 1: Open the Phone app.
Step 2: Here, you use the keyboard to press *#07#.
Step 3: Tap call or wait for your device to automatically answer the code.
This will immediately open a new window. Now scroll through this page and check the phone radiation level for your device.
On iPhone
Step 1: On your iPhone, open the Phone app.
Step 2: Then, dial *#07# and press the call icon.
Step 3: Here, tap RF Exposure.
Step 4: Scroll down and tap the SAR value link.
This will open detailed information about your iOS device’s RF exposure values in a separate web browser.

2. Use the Manufacturer’s Website
Some cell phone manufacturers, such as Apple, Samsung, Sony, etc., have RF exposure values listed on their websites. All you need to do is determine the model details of your device, visit the relevant mobile device manufacturer’s website and check the listed information.
To find detailed information about your cell phone model, you can check the box that came with your phone or, if available, on the back cover of your cell phone. You can also open the Settings app on your device and check the phone details listed there.
3. Check your phone box
If you have your smartphone box, you’re in luck. Some mobile companies, such as Samsung, Apple, ASUS, etc., print information about your device’s phone radiation on the box. So go through all the printed information and usually below the device’s IMEI information look for Cellular Radiation (SAR Value).

4. Use your device’s User Guide
Almost all devices come with their manuals. In addition to having information about the device’s hardware, functions, accessories, etc., it may sometimes contain relevant information about the device’s RF exposure values. To check this, see your device’s manual and see if it has a section for RF exposure or SAR Value.
5. Use of the FCC Website
Products certified by the Federal Communications Commission (FCC) will be assigned an FCC ID for the same product. It can usually be found in your phone’s manual. This FCC ID can then be used to check the radiation level of the phone through the official FCC website. This is the way.
Step 1: Open the FCC website in 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, press the search button.
The FCC website will now scan its database and provide you with the SAR Value for the product associated with the entered FCC ID.
6. Use Settings on your device
Besides using the USSD code to check the SAR value, you can also use your phone’s Settings menu to get relevant information about the SAR value. Follow the steps below to do that.
On Android
Note: We are using a Samsung Galaxy device for demonstration. RF exposure access options for your Android device may vary.
Step 1: Open Settings and scroll down.
Step 2: Here, tap About phone.
Step 3: Then, tap Legal Information.
Step 4: Tap Safety info.
Now scroll through the information mentioned and find the RF exposure section. Then check your phone’s radiation level.
On iPhone
Step 1: Open Settings and tap General.
Step 2: Scroll down and tap on ‘Legal & Regulatory’.
Step 3: Tap RF Exposure.
Step 4: Find the SAR value link and click it.
This will open the page in a separate web browser, providing detailed information about your iOS device’s current radiation levels.
7. Do a Google Search
While a Google search may not yield the most accurate results, in certain cases it can help you find out the SAR value of your iPhone 14 or any other device model. Make sure you specifically mention the device details for accurate results. Follow the steps below to do that.
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, make sure to double-check this result with at least one official source, as Google search results may be outdated or inaccurate for certain devices.
FAQ to check your phone’s SAR value
1. What SAR value is considered safe?
The FCC regulatory safe exposure limit is set at an SAR of 1.6 watts per kilogram (1.6 W/kg).
2. Can you check the SAR value for your device using the app?
While there are a number of mobile apps available that can help you check your device’s SAR value, we recommend against using them. This is because certain applications may request access to sensitive device information to check information regarding SAR Values. This can ultimately jeopardize your device’s security.
