SAR (Specific absorption rate) - definition
We know, a mobile device radiates Electro-magnetic Field Radiation around when it is being used. SAR is the measurement to measure how much energy is absorbed by a human body mass when a device is emitting the radiation nearby. There are specific standards of SAR and it may vary depending on the law in different countries. But more or less reputed brands try to keep the SAR value inside the permitted value suggested by all different regions. There are two values in SAR measurement; one is minimum and maximum absorption rate.
