Nine keys save more electricity. The 26-key keyboard needs more power to operate, while the 9-key keyboard only needs a little power, which can save electricity and prolong the use time of the mobile phone.

The origin of nine-key input method;

In the past, long-distance communication was basically realized by telegraph, which was not only troublesome to send, but also troublesome to interpret information. It is said that laziness makes people progress, so the prototype of modern telephone appeared.

In the 1990s of 19, although we didn't have to bother to send telegrams, we could transmit sound, but all we needed was a desperate crank and no telephone number. We need to tell the "switchboard operator" orally and ask someone there to transfer us before we can get through.

The demand for telephone calls is increasing, and operators can't meet it. Therefore, in 1930, the United States began to use the telephone layout of E. 16 1, and defined the telephone keyboard with the key 12, which contains not only numbers but also letters.

But now Jiugong doesn't use the letters on the keys to type, for fear that people can't remember the phone number. Recording with letters, such as the telephone number of 4263-7663-269, can you record it beautifully? Boy, you don't have to remember many numbers.

Because the letters on the early buttons only played the role of an auxiliary record, there were no Q and Z in the buttons, so they could not be used to send text messages. It was not until 1988 that 26 letters were completely stuffed into 9 buttons on the mobile phone.

Imported products such as telephones will inevitably be introduced into China together with the letters on the number keys, so the numbers and letters of fixed telephone keys have become the "nine squares" that many people first come into contact with.

With the development of the times, the BB machine has been pushed out of the historical stage, and the push-button mobile phone with short message function was born. Although you can send short messages by mobile phone, at that time, all mobile phone manufacturers had their own 9-key input method, which was very troublesome to input.
