Check Radiation level (SAR) of your Smartphone by USSD code *#07#

Smartphone has so much penetrated radiation_levelin our daily life that now no one can think of without it. Excessive use of smartphone may cause health problems but if you are even using less a smartphone with bad SAR, that is most dangerous.

Here SAR stands for Specific Absorption Rate which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone. Federal Communications Commission (FCC) has adopted limits for safe exposure to radio frequency (RF) energy  which is  1.6 watts per kilogram (1.6 W/kg).  Any smartphone  at or below this SAR levels is “safe” to use.

You can check Radiation level in terms of SAR of your smartphone by dialing a USSD code *#07#, if results shows SAR below 1.6 watts per kilogram (1.6 W/kg) then it is OK otherwise you are advised to change your smartphone immediately.

Here are SAR level of some popular smartphones in the market.

  • iPhone 6:>>  1.59 W/kg
  • LG G3:>> 0.99 W/kg
  • LG G2:>> 1.44 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
  • HTC One (M8):>> 1.29 W/kg

Interestingly iPhone 6 have just 0.01 below the threshold level of SAR.

In addition to radiation level you must know about following important USSD codes to get more information of your smartphone.

*#*#4636#*#* : It gives a lot of information of  smartphone under 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 may times and how much time every app on your smartphone you have used. Interestingly WhatsApp is on top of the list on my smartphone. Am I using WhatsApp the most !!
  • Wi-Fi information: It shows Wi-Fi API, config and status

*#06# : It shows the IMEI number of your phone which is a 15 digit unique number for your phone, basically it is  Social Security number of your phone. Sometimes when typing in *#06# it will add an additional 2 digits at the end. The first 15 digits shown before any space or dash is your IMEI.
