What are the uses of “airplane mode” on mobile phones?

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

1. The main function of airplane mode is to cut off signal reception, that is, the mobile phone cannot make calls, and others cannot call in. Mobile data traffic cannot be used to send and receive text messages, but other functions can still be used normally.

2. When sleeping at night, turning on airplane mode can not only reduce radiation, but also save power. I don’t want to turn off my phone when going to bed at night, but I am also worried about radiation problems. Some brands of mobile phones even have alarms that don’t work after they are turned off, which is very inconvenient. When the flight mode is turned on, the radiation is very small, and it saves power. It does not delay waking up suddenly in the middle of the night to check the time, and the alarm function can still operate normally.

3. In some places where the signal is poor and often intermittent, turning on airplane mode can save more power. I once took a train, and there were many mountain roads and tunnels in the middle. The signal was always connected and disconnected, which was very power-consuming. Turning on airplane mode at this time can save the power of the phone, and then turn off airplane mode after the signal is stable.

4. When charging your phone, if you want to charge it more quickly, you can turn on airplane mode. After the mobile phone stops searching for and receiving signals, it will speed up the charging process and save charging time.
