Qualcomm – No Problems Regarding Quick-Charge Technology and USB-C Connections

The Quick Charge technology of Qualcomm and the USB Type-C connection are not compatible, well, according to one Google engineer. However, two new flagship mobile phones have such technologies found in one device, and these are the HTC 10 and the LG G5.

Qualcomm defended their technology by issuing a statement that says they have “received no reports of user experience or device malfunction issues with or without USB Type-C connectors.” The USB Type-C specification requires that a port’s Vbus line sits between 4.45 and 5.25-volts, as what Android Authority outlines. For the Quick Charge technology, the company responsible for such a feature said in a statement that “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.”

When users are making use of the Qualcomm’s Quick Charge 3.0 technology, the feature promises to juice up a conventional smartphone from 0 all the way to 80-percent is approximately 35-minutes. However, not everyone about the aforementioned technology is a far. Benson Leung, a Google engineer and also a USB evangelist of sorts, had first discussed his concerns over the use of both technologies in one device back in a November blog post as to whether the two techs can coexist on the same connector. To summarize what the Google engineer had said in his blog post, he said, “Type-C Spec forbids it.”

The company responsible for the Quick Charge tech had rebutted, however, saying that the technology “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. 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.”

ExtremeTech explains, however, that the previous statement does only little to clarify things with regards to the Qualcomm technology and USB-C connections. The PCMag sister company says, “It is not clear what will happen if [the HTC 10 and LG G5] are plugged into other hardware that implements USB Type-C, because it’s impossible to prove that non-compliant devices will be compatible with compliant hardware (the entire point of having a specification is to avoid issues like this).”
