Although SAR values might vary for different models of phones
or even for different positions of the same model, they are all
compliant with regulations pertaining to safe level of radiation.
According to WHO current research, there is no need to apply
any special restrictions in using portable devices. According to
WHO, in order to reduce radiation, a length of conversation
should be reduced, or headphones or speakerphone should be
used, or the phone should not be held in proximity to head or
body.
The highest SAR value in tests

SAR – device next to
