Xiaomi Mi A1, OnePlus 5T top phones emitting highest radiation, shows report

Xiaomi and OnePlus devices dominate the list of smartphones emitting the highest radiation levels compiled by Statista based on data from the German Federal Office for Radiation Protection.

Chinese smartphone maker Xiaomi’s Mi A1 device emits the highest level of radiation, which is followed by OnePlus 5T. This is based on research conducted by the German Federal Office for Radiation Protection and this data was collected by Statista, which made made two lists of top 16 smartphones emitting the most radiation and the least radiation.

When it comes to Specific Absorption Rate (SAR) value or radiation emitted by phones, the maximum acceptable value is around 1.6 W per kg. A lower SAR rating indicates lower radiation being emitted. In Germany the SAR limit is 2W per kg, so while these phones are emitting higher radiation, they are still within the limit in Germany.

While Xiaomi and OnePlus devices dominate the list of phones emitting the highest radiation, Samsung phones are found mostly in the least radiation list. Statista clarifies that while there isn’t any universal guideline for a safe level of phone radiation, the German certification for environmental friendliness called ‘Der Blaue Engel’ or Blue Angel only certifies models that have a specific absorption rate of 0.60 watts per kilogram or less.

Highest radiation emitting phones

Topping the chart of phones with the highest radiation levels, Xiaomi Mi A1 emits a specific absorption rate of 1.74 watts per kilogram, which is slightly higher than the 1.6W per kg that is seen as the standard. Coming in second place, OnePlus 5T has an absorption rate of 1.68 watts per kilogram.

Another Xiaomi phone, Mi Max 3 takes the third spot with a specific absorption rate of 1.58 watts per kilogram, whereas OnePlus 6T sits on the fourth number with a specific absorption rate of 1.55 watts per kilogram.

Commenting on the findings, Xiaomi responded, “All Xiaomi smartphones sold in India comply with the laws for SAR values and are well under the limit. Mi A1 has a SAR value of 1.26 W/kg (head) and 0.17 W/kg (body) in India.”

“Values shared in the said report have been obtained from tests in Germany (where the conditions and standards for SAR testing and values are different from those in India) and thus cannot be compared to SAR values in India. For reference, India has a maximum limit of 1.6 W/kg while in Germany, the limit is 2.0 W/kg,” it added.

Apart from above-mentioned models, Xiaomi Redmi Note 5 (1.29), OnePlus 5 (1.39) and OnePlus 6 (1.33) also make it to the list.

The list also includes the iPhone 7 with a specific absorption rate of 1.38 watts per kilogram and iPhone 8 with a specific absorption rate of 1.32 watts per kilogram. The list of 16 devices goes on to include Google’s flagship devices– Pixel 3 XL (1.39) and Pixel 3 (1.33) as well.

Lowest radiation emitting phones

Statista also compiled the list of phones emitting the least radiation based on the German body’s data. With eight models in top 16, the list is dominated by Samsung devices with Galaxy Note 8 at the top with a specific absorption rate of 0.17 watts per kilograms.

Other Samsung smartphones in the list include Galaxy A8 (0.24), Galaxy S8+ (0.26), Galaxy S7 Edge (0.26), Galaxy S9+ (0.29), Galaxy J6+ (0.31), Galaxy J4+ (0.32) and Galaxy S8 (0.32).

The list also includes models like ZTE Axon Elite on the second spot with a specific absorption rate of 0.17 watts per kilograms and LG G7 ThinQ on the third spot with a specific absorption rate of 0.24 watts per kilograms.

HTC U11 Life (0.28), LG Q6/Q6+ (0.28), Moto G5 Plus (0.30), Moto Z (0.30) also make it to the list of least radiation emitting devices.
