Mobile phones have become a daily necessity, but concerns about mobile radiation are also increasing. One term you may have seen while buying a smartphone is SAR value. Many users don’t clearly understand what it means or how important it really is.
Many people use smartphones daily without knowing about SAR value and its impact on health. SAR (Specific Absorption Rate) measures the amount of radiation absorbed by the body when using a mobile phone. In this guide, we explain SAR value in simple terms and whether your phone is safe to use.
In this guide, we’ll explain what SAR value is, what is considered safe in India, and how you can check SAR value on any smartphone in a simple and practical way.

What Is SAR Value in Mobile Phones?
![]() |
| SAR value measures radiofrequency energy absorbed by the human body |
SAR stands for Specific Absorption Rate. It measures the amount of radiofrequency (RF) energy absorbed by the human body when you use a mobile phone.
Key Points About SAR Value
- SAR value is measured in watts per kilogram(W/kg)
- It shows how much radiation your body absorbs from the phone
- Every mobile phone sold must meet safety SAR limits
- SAR testing is done in controlled laboratory conditions, not during real-life usage
Why SAR Value Is Important for Users
SAR value helps users understand whether a phone follows safety guidelines.
Why You Should Check SAR Value
- Higher SAR means more radiation absorption
- Lower SAR means less radiation absorbed by the body
- Regulatory authorities set limits to reduce health risks
However, SAR value alone does not determine overall safety. Usage habits matter even more.
What Is the Safe SAR Limit in India?
![]() |
| The maximum permitted SAR value in India is 1.6 W/kg |
India follows strict mobile radiation standards.
India SAR Guidelines
- India SAR limit: 1.6 W/kg (averaged over 1 gram of tissue)
- This limit is the same as the USA
- It is stricter than some other countries
Any phone sold legally in India must stay within this limit.
How to Check SAR Value on Any Smartphone
![]() |
| SAR value can be checked using *#07# or phone settings |
You can check SAR value using multiple methods. Here are the most reliable ones.
Method 1: Check SAR Value Using the Phone Dial Code
This is the fastest method.
- Open your phone dialer
- Dial: *#07#
- SAR information will appear on the screen
This method works on most smartphones.
How to Check SAR Value on Android Phones
![]() |
| Android users can find SAR value in About Phone settings |
Android users can check SAR value in several ways.
Android SAR Check Methods
- Use *#07# dial code
- Check the phone box or user manual
- Go to settings → About phone → Legal Information
- Search the phone model on the manufacturer's official website
How to Check SAR Value on iPhone
![]() |
| iPhone SAR value is available in legal and regulatory settings |
Apple provides SAR information clearly for all models.
iPhone SAR Check Methods
- Use *#07# dial code
- Go to Settings → General → Legal & Regulatory
- Check Apple's official website by model name
- SAR value is also printed on the phone box
Does a Lower SAR Value Mean a Safer Phone?
![]() |
| A lower SAR value does not always guarantee lower real-life radiation exposure. |
Things You Should Know
- SAR is tested under maximum power conditions as per world health organization (WHO)
- Real- life usage varies depending on signal strength and usage style
- A phone with low SAR can still expose you to radiation if used improperly
Safe usage habits are more important than chasing the lowest SAR number.
SAR Value vs Real-Life Mobile Phone Usage
![]() |
| Daily mobile usage habits affect radiation exposure more than SAR value alone. |
Examples of High Exposure Habits
- Long calls increase exposure
- Weak network signals increase phone power output
- Keeping the phone close to the body increases absorption
Even a low-SAR phone can expose you to more radiation if used carelessly.
How SAR Value Connects With Mobile Radiation Exposure
SAR value shows potential exposure, but actual exposure depends on how you use your phone.
Tips to Reduce Mobile Radiation Exposure
- Use speaker mode or earphones
- Avoid long calls
- Don't keep the phone near your head while sleeping
- Avoid calls in low signal areas

Common Myths About SAR Value
![]() |
Many popular beliefs about SAR value and mobile radiation are misunderstood. |
Popular SAR Myths Explained
- Lower SAR means zero radiation ー False
- High SAR phones are illegal ー False
- Anti-radiation accessories replace safe habits ー False
SAR value is only one safety indicator, not a complete solution.
Final Verdict: Should You Worry About SAR Value Too Much?
![]() |
| Balanced mobile usage habits matter more than worrying about SAR numbers. |
SAR value is important, but it should not create fear.
Final Thoughts
- All phones sold in India meet SAR safety limits
- Normal usage within limits is considered safe
- Smart usage habits are the real key to safety
Instead of worrying too much about numbers, focus on balanced and responsible phone use.
Conclusion
Understanding SAR value helps you make informed decisions while buying and using smartphones. While it is a useful safety measure, it should always be combined with smart daily habits to reduce mobile radiation exposure.
A little awareness goes a long way in using technology safely.
Frequently Asked Questions About Mobile Phone SAR Value
What is SAR value in mobile phones?
SAR value (Specific Absorption Rate) measures the amount of radiofrequency radiation absorbed by the human body when using a mobile phone. It is expressed in watts per kilogram (W/kg).
What is the safe SAR limit in India?
The safe SAR limit in India is 1.6 W/kg, averaged over 1 gram of body tissue. Any smartphone sold legally in India must comply with this limit.
How can I check SAR value on my smartphone?
You can check SAR value by dialing *#07# on your phone, checking the phone box, viewing legal information in settings, or visiting the manufacturer’s official website.
How to check SAR value on Android phones?
On Android phones, SAR value can be checked using *#07#, through Settings → About Phone → Legal Information, or by checking the official brand website.
How to check SAR value on iPhone?
On iPhones, you can dial *#07#, go to Settings → General → Legal & Regulatory, or check SAR details on Apple’s official website by model name.
Does a lower SAR value mean a safer phone?
Not necessarily. SAR value is tested under maximum power conditions. Real-life exposure depends more on how you use your phone, signal strength, and call duration.
Are high SAR value phones illegal in India?
No. All phones sold in India are tested and approved under SAR limits. Phones exceeding the limit are not allowed for sale.
Can mobile phone radiation be reduced?
Yes. Using earphones, speaker mode, avoiding long calls, and not using phones in low-signal areas can significantly reduce radiation exposure.
