According to World Health Organization electro-magnetic radiations can damage you. Electromagnetic radiations emit from every device including mobile phones. The electromagnetic radiations are measured form Energy Absorption Test which is also called SAR. Apple’s iPhone 7 and iPhone 7 plus has electromagnetic radiations that are high on SAR.

Firstly, these devices should be kept away from head. According to website Business Korea, Samsung Galaxy S7 Edge has lowest electromagnetic radiations. Following are the phones that have very high SAR level.

1. Huawei Honor 8 – SAR of 1.5
2. Huawei P9 – SAR of 1.43
3. iPhone 7 – SAR of 1.38
4. iPhone 7 Plus – SAR of 1.24
5. Huawei Honor 5C – SAR of 1.14
6. Sony Xperia X Compact – SAR of 1.8
7. Sony Xperia XZ – SAR of 0.870
8. LG G5 – SAR of 0.737
9. Sony Xperia X – SAR of 0.720
10. Samsung Galaxy A3 – SAR 0.621

The only way to avoid radiation is excessive usage of phone, especially excessive calling and headphone usage.

Companies should check their SAR level before manufacturing smartphone.
