For the state bodies that approve the sale of mobile phones, the level of radiation emitted by the devices is extremely important because it is a determining factor for allowing the sale of a certain terminal. Making a comparison between iPhone 4S si Samsung Galaxy S III it was discovered that the Samsung terminal emits radiation at a level 3 times lower than that recorded for the Apple terminal. The news isn't great, but it's much better than for those who own one BlackBerry, because they are subject to a much higher level of radiation.
Do these data matter? Yes, it matters for the statistics because no iPhone owner will throw the device in the trash after seeing them, nor will he know the SAR of any other mobile phone he buys because stores do not provide such information.
