The HTC 10 and the LG G5 are flagship phones for their respective companies, and each is equipped with flagship features like USB Type-C ports and fast charging. But both HTC's and LG's newest models employ Qualcomm's Quick Charge 3.0 standard, and that's drummed up some worry in a particular part of the mobile phone community. Google's Benson Leung said in November that "any USB Type-C charger" that claims to support Qualcomm's quick charging standard is "breaking" the specs laid out by the USB Implementers Forum, and that has some people worried about problems like overheating.
The concern reached enough of a pitch that Qualcomm issued a statement over the weekend:
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.
Qualcomm makes it sound like everything's good here, and the phones (and the chargers) have all passed certification. But Engadget seems to side with Leung, citing how Google opts against using Quick Charge on its own Type-C-enabled Nexus 5X and Nexus 6P primarily because of this concern. Either way, the methods that Qualcomm uses to deliver power in order to accomplish its fast charging don't appear to jive with the specs laid out by the Implementers Forum, even if the company says there are "no reports" of malfunction.
