We’ve heard a lot about strong radiation producted by your phone when charging with only one bar of power left.


The amplitude of the electromagnetic field (radiation) represents the signal transmitting power. Thus, there’s nothing about how much the phone power left. In fact, the amplitude of radiation is controlled by phonebase stations. It would increase the amplitude of radiation if the phone is in a condition of weak signal to guarantee normal communication, and to the contrary it would decrease the amplitude of radiation if the phone is a strong signal.

So it’s concluded that the weaker the phone signal, the stronger the radiation.

However, What a weak phone signal can do to our body?

Actually, the amplitude of radiation would increase 1000 times than in an ordinaty situation, but it wouldn’t do harm to our body and has nothing about cancer.
