This year's iPhone 12 series introduced 5g support for the first time, but judging from the information on Apple's official website, it seems that this is exactly why,The amount of radiation has also increased, and even become the largest iPhone so far。
In short,The maximum SAR of iPhone 12 Mini is 0.910 w / kg483 w / kg, 12 Pro is 0.483 w / kg, 12 Pro Max is 0.436 w / kg.
According to the comparison and query, as the highest radiation mobile phone in the iPhone 12 series,The value of 12 Mini is 3.5 times that of last year's iPhone 11 Pro max (model a2220, SAR 0.260 w / kg)。
Of all the SAR models listed on Apple's official website, the smallest is 0.240w/kg of the iPhone XS max (model A2104).
It should be noted that,Even if it is 0.910 w / kg of 12 mini, it is fully in line with the national mandatory standard gb21288-2007 "local exposure limits of electromagnetic radiation from mobile phones". The upper limit specified in the specification is not more than 2.0 w / kg。
Of course, SAR will not affect health as long as it is within the limit. Meanwhile, the lower the SAR value is, the less radiation is absorbed by the brain.
According to the data, the European Union, like China, requires SAR at 2.0w/kg, while the FCC of the United States is more stringent, which should not exceed 1.6w/kg. In addition, the SAR given by the regulatory authorities is generally conservative, and it is generally believed that SAR less than 50 times of the above standard is actually safe.
