Qualcomm: Fast Charging Won’t Affect Your Phone Over USB-C


Recently, a Google engineer had suggested that two Android Smartphones, HTC 10 and LG G5 do not comply with the USB Type-C specification.

Although the much talked about USB Type-C offers faster charging and makes it easier for the users, it also raises some compatibility concerns. They also reason out that the faulty cables can end up burning your favourite devices.

Google’s Benson Leung claims that Qualcomm’s Quick Charge 3.0 technology which is found in the HTC 10 and the LG G5 violates the USB Type-C spec.

USB Type-C spec notes that the Vbus line of the port would range between 4.45 and 5.25 volts, but the Quick Charge raises the voltage 9 or 12 volts, which violates the specifications of the port.

“I don’t recommend any Qualcomm QC 3.0 USB type-C charger, because any of them that claim to support QC 3.0 on a Type-C port violates the Type-C specification. The Type-C spec specifically forbids proprietary charging methods that try to change Vbus beyond 5V,” warns Leung.

The chipmaker had made an official statement regarding the USB Type-C and Quick Charge 3.0 concerns, as noted by Android Central.

“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 standards,” said Qualcomm (via Android Central).

However, the company has stated that they have yet to receive any complaints or reports of issues concerning any device malfunction or user experience.

Although the statement claims no safety concerns and no reported issues, Qualcomm did not refute the voltage might unconstructively influence the device or user experience. They pointed out that OEMs have the ability to adjust based on their specific devices.
