Now the charging speed of smart phones is getting faster and faster, the iQOO 10 Pro just released not long ago is even equipped with a 200W ultra-fast flash charge, and the fast charging power of Huawei, Xiaomi, OPPO and other brand mobile phones has also reached more than 100W. Usually charging a mobile phone, the fastest 10 to 20 minutes can be full, greatly improving the daily charging efficiency, but also let users feel the convenience brought by technology.
But now the mainstream domestic mobile phone fast charging uses a private protocol, that is, the same support 120W fast charging of two different brands of mobile phones, if the exchange of chargers, it is not up to the highest power, or even only the use of 10W slow charging. Therefore, for users who use two different brands of mobile phones at the same time, it is indeed a bit troublesome to find the corresponding charging head for each charge.
Therefore, the China Communications Standardization Association recently launched the establishment of the "Terminal Fast Charging Technology and Standard Promotion Committee" in Beijing, and the person in charge of the Ministry of Industry and Information Technology said that a unified charging standard system based on independent technology will be built as soon as possible.
As soon as the news came out, it immediately attracted a lot of netizens to applaud, after all, if a charging head can quickly charge all mobile phones, it is not only convenient to use, but also saves the cost of purchasing a charger. Therefore, the unified fast charging standard of smart phones is definitely in favor of both hands for users.
However, some insiders have proposed that the domestic mobile phone fast charging agreement is not universal, the main reason is that domestic brands usually take fast charging as one of the main selling points, and the competition is very fierce, you support 30W, I have to support 60W, and finally slowly increased to 100W, 200W. That is to say, the domestic brand in the field of fast charging technology research and development investment is still relatively large, high-power fast charging is often the "secret weapon" of each brand, naturally unwilling to be compatible with each other.
And because of the small size of smart phones, it is not easy to achieve high-power fast charging, which requires the interaction of battery materials, charging chips and many other links, and the technology of each manufacturer is also different. For example, the same is 120W fast charging, Xiaomi mobile phone uses a single cell battery, vivo mobile phone uses a dual battery. The fast charging technology of various manufacturers is different in terms of research and development and manufacturing costs.
On the other hand, the formulation of standards means that it is easy not to change. Therefore, some users are worried that if the standard of fast charging power is low, will it affect the technological innovation of mobile phone manufacturers? Especially in the past two years, the increase in mobile phone charging power is very fast, 100W fast charging has not yet become the mainstream, 200W fast charging has been mass-produced and listed. At this rate, a super fast charge of 300W or even 500W is not impossible. The development of mobile phone fast charging technology can also drive the common progress of battery materials, charging chips and other fields, which is very beneficial to the entire industry.
Of course, there is also a compromise solution is that the management department proposes a standard fast charging power, such as 50W or 65W, and the future listed smartphones can exceed this fast charging power standard, but it must also ensure backward compatibility. That is to say, a mobile phone can support 200W private fast charging, but it must also be compatible with 50W standard fast charging. In this way, when the mobile phone uses a non-original charger, it can also reach the standard fast charging of 50W. In real time, for a mobile phone with a battery capacity of about 4500mAh, it takes less than 1 hour to use 50W fast charging to full charge, although this speed is not as fast as private fast charging, but it is completely enough for most users.
In this way, mobile phone manufacturers can continue to pursue higher charging power, but also to ensure that users can use different charging heads can get a basic fast charging experience, users can also choose the original charger or universal charger according to their actual needs. At present, many mobile phone chargers are already compatible with standard fast charging protocols such as USB PD (PPS).
