What is the use of the flight mode of the mobile phone?

Mobile phone flight mode is also called aviation mode, which means that the mobile phone must be turned off during flight to avoid the influence of the transmission and reception of mobile phone signals on aircraft flight. Some mobile phones have this function, which can turn off the signal transmission and reception of SIM card.

And it is realized by some software. For example, there is an aviation mode in the system tool of S60 software, which can turn off the function of the SIM card, so that the mobile phone is in a state of not sending and receiving signals, and does not affect other functions of the mobile phone (generally, the mobile phone cannot operate without the SIM card).

It is said that the earliest flight mode came from Huawei. Li Changzhu, vice president of Huawei's consumer business mobile phone product line, invented the patented technology of flight mode. The original intention of the design is to prevent the mobile phone signal from interfering with the instruments on the plane and ensure flight safety. In other words, this flight mode is a function independently developed by China.

? The flight mode is to turn off the telephone communication function, that is, you can't answer the phone and send text messages, and there is no signal contact with the base station. Don't try to contact the base station. Because the mobile phone signal will interfere with the electronic equipment on the plane, it is not allowed to turn on the mobile phone on the plane. In this mode, the related functions of the mobile phone signal are turned off.

You can turn on your phone and continue to use other functions, such as looking up the phone book and enjoying articles and movies on your phone. So it's called flight mode. Most of the power of the mobile phone is consumed by the signal. Turning off the signal in flight mode is very energy-saving.

The function of flight mode, with the civil aviation allowing the use of mobile phones in flight mode on the plane, the function of this chicken rib is no longer chicken rib, because it is finally useful. But in fact, it has other small functions besides disconnecting the network and signal.

Someone has done the experiment of fast charging in flight mode. When charging in airplane mode, the charging time of the mobile phone will be much faster, and the charging time of the Apple mobile phone will be shortened by 18 minutes.
