How to Check Radiation Level (SAR) of Smartphone 2023

No one can imagine living without a smartphone nowadays since they have become so ingrained in our daily lives. Even while using a smartphone moderately with poor SAR, which is also the most hazardous to health, excessive usage of smartphones may result in health issues.

What is SAR?

A mobile phone or other wireless radio equipment broadcasts, and the amount of RF power that is deposited in the human head or body is measured as the Specific Absorption Rate (SAR). During SAR compliance testing, the maximum SAR value (measured in Watts/kilogram) is determined.
Before being sold in any market, all mobile phone models must pass tests to ensure that they adhere to local, national, and international exposure limitations for radiofrequency emissions.

Since mobile phone models are tested at their maximum power levels in laboratories to verify compliance, the SAR values provided for each model sometimes dramatically exaggerate real-life exposure levels.

During normal use, mobile phones typically don’t operate at their highest power capacities.

Mobile phones constantly adjust to the minimal power needed to make and maintain a call in order to prevent network interference, increase battery life, and increase available call time.

 

USSD Code *#07#

You can check the SAR level of your smartphone by dialing a USSD code *#07#, which will display the SAR value; if the results reveal SAR less than 1.6 watts per kilogram (1.6 W/kg), it is OK and your smartphone is safe to use; otherwise, you should update your smartphone immediately.

SAR levels of some popular Smartphones.

  • Apple iPhone 14 Pro Max : 1.15 W/kg
  • Apple iPhone 13 : 0.99 W/kg
  • Apple iPhone 11 Pro Max : 1.16 W/kg
  • Apple iPhone SE : 1.17 W/kg
  • Apple iPhone 6:>>  1.59 W/kg
  • LG G3:>> 0.99 W/kg
  • LG G2:>> 1.44 W/kg
  • Samsung Galaxy S20: 0.76 W/kg
  • Samsung Galaxy S10: 0.26 W/kg
  • Samsung Galaxy Note 2:>> 0.42 W/kg
  • Samsung Galaxy Note 3:>> 1.07 W/kg
  • Samsung Galaxy Note 4:>> 1.20 W/kg
  • Samsung Galaxy S5:>> 1.28 W/kg
  • Samsung Galaxy S21 FE 5G: 0.95W/kg
  • HTC One (M8):>> 1.29 W/kg
  • Xiaomi Note 10: 1.107 W/kg
  • Xiaomi Redmi Note 11 Pro Plus 5G: 0.861 W/kg
  • Xiaomi Mi A1: 1.75 W/kg
  • Redmi Note 9: 0.795 W/kg
  • Redmi Note 9 Pro: 0.662 W/kg
  • OnePlus Nord: 1.27 W/kg
  • OnePlus Nord CE 2 Lite 5G: 1.186 W/kg
  • OnePlus 8 : 0.96 W/kg
  • OnePlus 5T: 1.68 W/kg

It’s interesting to note that the SAR threshold for the iPhone 6 is just 0.01 below. While the majority of smartphones on the market are secure and have SAR values below the crucial value. The most recent 5 G-enabled phones, as you can see above, have a safer SAR value.

You need to be aware of the following crucial USSD codes in addition to the radiation level if you want to learn more about your smartphone.

USSD Code *#*#4636#*#*

This USSD code gives a lot of information about the smartphone under the following four categories.

  • Phone Information: It shows IMEI, Signal strength, etc.
  • Battery Information: It shows battery status, level, health, voltage, temperature, technology, and time since boot.
  • Usage statistics: it shows how many times and how much time you used every app on your smartphone. Interestingly WhatsApp is at top of the list on my smartphone. Am I using WhatsApp the most !!
  • Wi-Fi information: It shows Wi-Fi API, config, and status

USSD Code *#06#

Dialing this USSD code from your Smartphone displays your phone’s IMEI number, which is a 15-digit unique number. Your phone’s IMEI is essentially its Social Security number. Sometimes the output of the USSD code *#06# is a 17-digit number. It adds two digits at the end. Your IMEI is the first 15 numbers seen before any space or dash. Note down your phone’s IMEI number in your diary; it will come in handy if your phone is stolen.

 

 

WHAT DOES A SAR-TICK DO?

To assist customers in learning more about the SAR for their mobile phone or wireless equipment, mobile manufacturers are working with the Mobile & Wireless Forum (MWF) to develop SAR Tick.
We do, however, want consumers to be knowledgeable about the use and interpretation of SAR results. This website is a part of that effort, but the MWF manufacturers will also start adding a SAR-Tick to user guides to make it easier for customers to get SAR information and to know that their phone model has been examined for conformity with local, regional, and global standards.

SAR-Tick Label Sample

SAR
The applicable national SAR limitations of 2.0W/kg are met by this product. The xxxx part of this user guide contains the precise maximum SAR values.
Use an authorized attachment, such as a holster, or keep the product xx cm away from your body when wearing it on your person to guarantee that the product complies with RF exposure regulations. Keep in mind that even if you are not placing a call, the product may still be transmitting.

This makes it evident to consumers that the product complies with national and international exposure regulations while also pointing out where they can find further information.
