Will it be faster to charge off? Will fast-charging affect battery life? You must have many questions about mobile phone charging.
On April 21, Zhang Jialiang, the father and chief scientist of OPPO VOOC flash charge, answered questions about mobile phone charging on Weibo.
Zhang said that some people think that the charging speed will be faster in the shutdown state. In fact, under the existing technical conditions, this kind of "shutdown charging faster theory" does not exist.
Zhang pointed out that the meaning of fast charging is to make life more casual and more convenient. 5V/1A and 5V/2A have several hours to deal with the current mobile phone battery capacity. Charging is accompanied by a string like a rope. I guess everyone won't like it.
Like 65W SuperVOOC super flash charging, it can be fully charged in 30 minutes, which is why fast charging is popular.
As for the concern about whether fast charging will affect battery life, Zhang gave a negative answer. Zhang explained that battery life is determined by several factors:
One is the manufacturing process of the battery. With the development of lithium batteries for so many years, its quality can be guaranteed.
The second is the battery usage scenario. Zhang pointed out a charging misunderstanding. Many people think that taking a data cable to plug and charge multiple times will cause the battery to go through many cycles.
In fact, the battery life cycle refers to the accumulation of a complete charge and discharge cycle, which is a complete process from a few percent to 100 percent. It can be counted as a single charge cycle, as long as the mobile phone is a qualified product of the brand manufacturer, don't worry about this problem at all.
In addition, Zhang said that since the development of batteries and fast charging, the energy density of batteries has grown from 400-500Wh/L to more than 700 Wh/L, and the growth rate is very considerable. Has been achieved.
