Network resource PhonAndroid conducted an investigation to study the level of radiation (SAR) among the most popular top-end smartphones and published its results. Among the subjects were: Galaxy S7 edge, iPhone 7, iPhone 7 Plus, Huawei P9, OnePlus 3 and other newcomers of this year.The minimum radiation was recorded at Samsung – 0.264 W / kg, ASUS ZenFone 3 with the indicator 0.278 W / kg took the second place. . At the same time, the result of iPhone 7 and iPhone 7 Plus was 1.38 and 1.24 W / kg, respectively, which is five times higher than that of the Galaxy S7 edge. But, as it turned out, the highest level of radiation was shown by the Chinese Huawei P9 and Honor 8. The first emits 1.43 W / kg, the second – 1.5 W / kg. Tops of the \W / kg) Lenovo Moto Z (0.304 W / kg) OnePlus 3 (0.394 W / kg) Samsung Galaxy S7 (0.406 W / kg) HTC 10 (0.417 W / kg) Sony Xperia XA (0.473 W / kg) Honor 5X ( 0.560 W / kg) Samsung Galaxy A3, released in 2016 (0.621 W / kg) 10 most dangerous smartphones: Honor 8 (1.5 W / kg) Huawei P9 (1.43 W / kg) Apple, iPhone 7 (1.38 W / kg) Apple iPhone 7 Plus (1.24 W / kg) Honor 5C (1.14 W / kg) Sony Xperia X Compact (1.08 W / kg) Sony Xperia XZ (0.870 W / kg) LG G5 (0.737 W / kg) Apple iPhone OS (0.720 W / kg) Sony Xperia X (0.720 W / kg) acc. As per FCC rules, SAR must not exceed 1.6 W / kg. In Europe, the rules are slightly softer and the permissible radiation value is 2 W / kg. Whether radiation is really harmful to the human body is not completely clear. Disputes are still ongoing on this issue. Manufacturers produce products in which the SAR does not exceed the standards acceptable in this country.
