Quick Charge (QC) is a proprietary battery charging protocol developed by Qualcomm, used for managing power delivered over USB, mainly by communicating to the power supply and negotiating a voltage. Quick Charge is used by devices such as mobile phones which run on Qualcomm system-on-chip (SoCs), and by some chargers; both device and charger must implement QC for QC charging to happen; if one doesn't implement it, regular USB charging happens.
