Turning off a mobile phone does not consume electricity, but it can \"leak\" electricity.
for the following reasons
1, as long as the battery is in the mobile phone, there will be a microcycle of the circuit, although the power consumption is very small, but the power will still be lost.
2, the battery is not an absolute closed environment, and the external heat exchange and other reactions lead to the loss of electricity, in addition to the self-cycling of the battery will also reduce the power.
Precautions when using mobile phone:
1. Don't let children under 12 use cell phones unless it's an emergency. In fact, developing children are the most sensitive to electromagnetic waves.
2, when making a phone call, keep the phone away from your body as much as possible, and the amplitude of the wave is reduced by 4 times every 10 centimeters, and the distance of 1 meter can be reduced by 50 times. Therefore, use the hands-free function as much as possible, or use a wireless headset with a distance of 20 centimeters, which is less electromagnetic radiation than the traditional wired headset, and Bluetooth headphones can also reduce electromagnetic radiation.
3, with the person you are talking to away from 1 meter, do not use mobile phones in public places, such as the subway, train or bus, otherwise you will make the people around you in a huge electromagnetic field.
