Among the six high-tech technologies that have changed the mobile phone industry, which one do you think is the most powerful?

Nowadays, the development of mobile phones is getting faster and faster, and many black technologies appear every year. Among them, many black technologies have even changed the development of the mobile phone industry and the current form of mobile phones. Let's take stock of the six black technologies that have changed the mobile phone industry and see which one is the most powerful.

1. Fast charging

In recent years, the battery life of mobile phones has become increasingly insufficient, but battery technology has reached a bottleneck and there has been no major breakthrough. Therefore, mobile phone manufacturers have focused on charging. Since the battery can only be made so big, can't I make the charging speed faster to improve the user experience? Therefore, OPPO equipped Find 7 with VOOC flash charging technology for the first time, increasing the charging power of the mobile phone from 5w and 10w to 20w, and the era of fast charging for mobile phones has officially begun.

2. Full screen

Nowadays, mobile phones are all full-screen, but a few years ago, mobile phones still used physical buttons, which looked very clumsy. In October 2016, Xiaomi released the first generation of MIX, and the full-screen era officially began. The screen-to-body ratio of mobile phones also began to increase continuously. The fact that we can use such a good mobile phone now is partly due to Xiaomi MIX.

3. Fingerprint under the screen

Apple users please ignore this feature. After the phone enters full screen, the original physical buttons are gone, and it is a problem where to put the fingerprint unlocking module. At first, everyone chose to put it on the back of the phone, but it was very inconvenient. It was not until the VIVO X20 Plus was equipped with an under-screen fingerprint for the first time that this problem was solved.

4. High refresh rate screen

High refresh screens have been around for many years on computers, but a few years ago, mobile phones all used 60Hz screens. It wasn't until May 2019 that the OnePlus 7 Pro was equipped with a 2K+90Hz high refresh screen for the first time, and everyone knew that mobile phones could be so smooth. Nowadays, mid-range and high-end phones are basically all high refresh screens, of course, the iPhone13 and iPhone13 mini are exceptions.

5.5G

In July 2019, Huawei Mate 20X 5G was released. This phone is the first 5G phone in China. Since then, the 5G era of mobile phones has begun. For a period of time afterwards, new mobile phones without 5G were embarrassed to be released. But now, Huawei's latest flagship phone does not support 5G for various reasons, which is really regrettable.
