In 2020, the next-generation flagships of major manufacturers will almost be on 5G. Except for Huawei and Apple, other mobile phone brands will mostly use the Snapdragon 865 + X55 platform. In addition, Nubia’s new flagship Red Magic 5G will also use a 144Hz screen. Now the company’s executives have revealed new evidence, suggesting that the Red Magic’s new flagship uses 100W fast charging.
This morning, Ni Fei, the CEO, and co-founder of Nubia posted such a Weibo, as shown below:
If you open the big picture, you can see that this is a screenshot of a mobile phone being charged. The voltage is 8.4V and the current is 9.6A. When calculated, it is more than 80W, which is higher than the current 65W level and closer to the upper limit of 100W. It is USB PD, and 100W power is just the highest level of USB PD fast charge.
Before Nubia, Xiaomi also demonstrated 100W fast charging technology before. Super Charge Turbo uses a dual-cell series design, adds two strings of battery technology, and adds a 98% ultra-efficient 2: 1 The charge pump, at the same time, uses extremely low impedance and high-cost materials, which can be filled with a 4000mAh battery in only 17 minutes.
However, the 100W fast charging technology has not yet been mass-produced. It still needs to solve difficult problems such as high cost, safety, and reliability. The 100W fast charging technology shown by Nubia may not be able to mass-produce, because the Red Magic 5G mobile phone that was previously connected to the network displays The charger model is NB-A1150A-USBA-C, and the charging power is up to 55W (11V / 5A).
From a practical point of view, the Red Magic 5G mobile phone is still more likely to use 55W fast charge, and the 80-100W fast charge should still be used for technology display.
