• Smartphones and SAR in 2019

    Statista has published a pair of infographics ranking late model smartphones based on how much radiation they emit. The means for quantifying this is what's called the specific absorption rate, or SAR, measured in watts per kilogram.

    The data was gathered from the German Federal Office for Radiation Protection; according to them anything below 0.6 watts per kilogram can be considered safe.



    If you're viewing this on your phone here's the list in text form, in descending order from the highest SAR:

    Xiaomi Mi A1 - 1.75 watts per kilogram
    OnePlus 5T - 1.68
    Xiaomi Mi Max 3 - 1.58
    OnePlus 6T - 1.55
    HTC U12 life - 1.48
    Xiaomi Mi Mix 3 - 1.45
    Google Pixel 3 XL - 1.39
    OnePlus 5 - 1.39
    iPhone 7 - 1.38
    Sony Xperia XZ1 Compact - 1.36
    HTC Desire 12 / 12+ - 1.34
    Google Pixel 3 - 1.33
    OnePlus 6 - 1.33
    iPhone 8 - 1.32
    Xiaomi Redmi Note 5 - 1.29
    ZTE Axon 7 mini - 1.29

    Chinese brands are among the worst emitters here but surprisingly, the latest Pixels—plus a pair of late-model iPhones—also make the list.



    And here are the phones with the lowest SAR, rearranged to match the order of the previous list:

    ZTE Blade V9 - 0.32 watts per kilogram
    Samsung Galaxy J4+ - 0.32
    Samsung Galaxy S8 - 0.32
    Samsung Galaxy J6+ - 0.31
    ZTE Blade A610 - 0.31
    Motorola Moto G5 Plus - 0.30
    Motorola Moto Z - 0.30
    Samsung Galaxy S9+ - 0.29
    HTC U11 life - 0.28
    LG Q6 / Q6+ - 0.28
    Samsung Galaxy S7 Edge - 0.26
    Samsung Galaxy S8+ - 0.26
    LG G7 - 0.24
    Samsung Galaxy A8 - 0.24
    Samsung Galaxy Note 8 - 0.17
    ZTE Axon Elite - 0.17


    It makes sense to see legacy OEMs like LG, Moto and Samsung here, as all of them were making mobiles back when they were primarily used for making phone calls.

    Keep in mind too, that exposure to radiation during calls can be minimized with a decent headset.
