The history of the rapid charging of mobile phones
Scenario 1: On August 8, 2019, Samsung's new generation mobile phone flagship note10 and Samsung note10+ were released in the US. During the period, the host on the stage showed that Samsung note10 supports 25W fast charging, and note10+ supports 45w fast charging. The next audience cheered, which means that Samsung has ended the five-year 9V1.67A AFC charging agreement dynasty since note4.
Scenario 2: On September 11, 2019, a new generation of iPhones was released in the US. Unlike the past, this iPhone11pro and iPhone11promax are equipped with 18w fast chargers for the first time. Although from iPhone8plus, the iPhone supports 18w fast charging. However, the 18w fast charger is standard in the mobile phone box, or the first time. Since then, the iPhone has ended the era of 5v1a safe charging, and finally joined the tide of fast charging.
Having said that, I am finally pleased to see that the international manufacturers are no longer grinding at the charging rate, and finally keep up with the pace of the times. In our lives, we often see Huawei's 40w charger charging the Xiaomi mobile phone with only 10w of power, but some so-called universal heads can quickly charge any mobile phone. The secret of this is the agreement for fast charging of mobile phones. Next, I will categorize the past and present of the fast charging of mobile phones.
The mobile phone charging protocol mainly has the following
PD protocol (USBPower Delivery): PD3.0, PD2.0
QC agreement: (QC4.0+, QC4.0, QC3.0, QC2.0)
