In late 2015, Qualcomm released Quick Charge 3.0. Using the same basic science and technology as they did with Quick Charge 2.0, you'll be able to charge phones using QC 3.0 compatible equipment even faster. In laboratory tests using a 2750mAh battery, a Quick Charge 3.0 enabled device went from 0% to 80% charge in 35 minutes, while a device without Quick Charge 3.0 using a conventional (5 volt, 1 amp) charger achieved just a 12% gain in the same 30 minutes.
It works using what Qualcomm is calling Intelligent Negotiation for Optimum Voltage (INOV). This is a new computational algorithm that allows the device being charged to determine the power level it needs at any point in time, which means it's always working with the most efficient and optimized power transfer rate. Support for a wider range of voltage options — 200mV increments from 3.6V to 20V — means your phone can dynamically target one of the dozens of charging levels.
Quick Charge 3.0 is implemented the same way previous versions were, and all QC 3.0 equipment is fully compatible with Quick Charge 2.0 and Quick Charge 1.0 devices. QC 3.0 supports USB Type-A, USB Type-C, and micro USB, as well as proprietary connections. It's easy for manufacturers to use QC 3.0 on a wide variety of chargers and devices.
