Cell Phone Radiation

Is it true that cell phone radiation is stronger when the battery is almost empty? Why? I see no reason.

No, cell phones emit electromagnetic radiation when they send a signal to the cell tower, low battery power may reduce the energy sent, but not increase it. That said, a mobile phone can increase its signal when it senses low / no signal from the cellular tower in order to ensure a good connection.

when the signal is weak, so you can clearly hear the other, it requires more power to transmit voice, so radiation is stronger.

stop calling when the signal is weak!

I have never heard about it. What I know is to enhance the radiation when the signal is weak.

Who are they? Someone who has equipment to measure the RF of a cell phone?

Cell phones Emmit radiation, so it does not work
