Google requires that all Android devices that are equipped with Type-C as an interface must notdestroy the compatibility of USB-PD.
Fast charging has become the standard of the mobile phone industry, and has gradually developed into a new "arms race" campaign. This year, we can see that more and more manufacturers are promoting their future power to be 50W, 65W or even 100W. The popularity of fast charging technology also makes mobile phone manufacturers no longer blindly design a mobile phone with a large and heavy battery, which is also beneficial to control the overall weight of the mobile phone, but the increasingly large number of private fast charging protocols are gradually coming into use, bringing inconvenience. And a third-party fast-charging head also needs to be compatible with a wide variety of fast-charging agreements to be sold well in the market. The increased cost is ultimately passed on to the consumers, and now Google is pushing the vendors to support the open standard of USB-PD.
Universal Description: USB Power Delivery (USB PD) is a fast charging standard developed by the USB-IF organization. It can realize power transmission of up to 100 watts and can freely change the direction of power transmission. It is the current mainstream fast charging standard. The USB-IF organization has released an important update of USB PD 3.0, and officially launched the PPS (Programmable Power Supply) charging specification, successfully collected Qualcomm QC4, and has reached a consensus with the Tera Lab of the Ministry of Industry and Information Technology. Thus, the uniting of USB PD fast charging has made significant progress.
At present, almost all mainstream mobile phone manufacturers have incorporated the USB PD fast charging protocol into the charging configuration of mobile phones (this is only one part of data, and there will be more mobile phone manufacturers to keep up with this rhythm. Of course, there will be more devices like notebooks, tablets, game consoles and others supporting USB PD fast charging. USB Type-C will also become the only interface for power and data transmission between electronic devices in the next decade. The uniting of USB PD fast charge protocol is coming soon) However, there are still large manufacturers such as Samsung that use the PPS (custom voltage and current) from the PD protocol to do their own fast charging protocol, which ensures compatibility with the standard, and fast charging power is also guaranteed.
And Google has been silently promoting PD compatibility for Android devices. In fact, in the late of 2016, Google’s Android 7.0 Nougat compatibility document strongly recommended that vendors not use the private fast charging protocol, because this would Initiate interoperability issues with USB-PD charging heads or devices, and Google has warned that they will require all Type-C devices to fully support standard Type-C chargers in the future.
For consumers, a unified fast charging protocol is definitely bring a lot of convenience in daily use. It is no longer necessary to consider whether this charging head or mobile power supply support my equipment or not.Consumers can directly use fast charging. But how much binding force does Google have to domestic manufacturers? Does this requirement written in the GMS requirements have binding force to mobile phones made in China? These questions have yet to be answered by the products from domestic manufacturers.
