What are the uses of the "airplane mode" on the mobile phone?

The flight mode of the mobile phone has the following functions:

1, the main function of airplane mode is to cut off signal reception, that is, mobile phones can't make calls, others can't call in, can't send and receive short messages, can't use mobile data traffic, and other functions can still be used normally.

2. When you sleep at night, turning on flight mode can not only reduce radiation, but also save electricity. I don't want to turn off my phone when I sleep at night, worrying about radiation problems. Some brands of mobile phones don't work even when they are turned off, which is very inconvenient. When you start the flight mode, the radiation is very small, and it saves electricity, so it doesn't delay waking up in the middle of the night to see the time. The alarm function can still operate normally.

3. In some places where the signal is not good, when it is often intermittent, turning on the flight mode can save more electricity. Once by train, there were many mountain roads and tunnels in the middle. The signal is always intermittent, which consumes a lot of power. At this time, turning on the flight mode can save power for the mobile phone, and then turning off the flight mode after the signal is stable.

4. When the mobile phone is charging, if you want to charge faster, you can turn on the flight mode. After the mobile phone stops searching for the received signal, it will speed up the charging process and save charging time.
