Earlier this week Google Engineer and USB C aficionado Benson Leung came out to state that he wouldn’t recommend the HTC 10 or the LG G5 due to issues with USB C, specifically with their use of Qualcomm’s Quick Charge 3.0 standard for fast charging. He stated that QC 3.0 was not compatible with USB C and violated Type C spec, meaning it has the potential to damage your device or charger.
Since then, Android Central has obtained a statement from Qualcomm regarding the issue.
Qualcomm Quick Charge is designed to be connector-independent. It can be implemented in a device that supports a variety of connectors, including USB Type-A, USB micro, USB Type-C, and others. When an OEM chooses to implement Quick Charge into their device, they can configure the voltage to fit within the specifications of the USB Type-C standard. We have received no reports of user experience or device malfunction issues with or without USB Type-C connectors. At Qualcomm Technologies, we are continuously working to provide the best solutions for our customers and consumers. Qualcomm Quick Charge is a leading edge fast charging solution with more than 70 devices and 200 accessories supporting one of the two most recent versions of Quick Charge, with even more currently in development.
To round that all up, essentially what the company is saying is that there haven’t been any issues with Quick Charge 3.0 over USB C. They do acknowledge that OEMs have the ability to change the voltage of QC 3.0, but they do not actually acknowledge that the fast charging standard breaks Type C spec.
