Qualcomm announced its third-generation fast charging technology, called Quick Charge 3.0. It can charge four times faster than traditional charging and twice as fast as Quick Charge 1.0, while also being 38 percent more efficient than Quick Charge 2.0 and reducing power dissipation by 45 percent.
Qualcomm's Quick charge employs an algorithm called Intelligent Negotiation for Optimum Voltage (INOV), which can determine how much power the device can take at any point in time, thus optimizing the power transfer and cutting down on charging times. It can support wide voltage options from 3.6 V to 20 V, in 200 mV increments, allowing the device to target dozens of power levels.
"We are significantly enhancing the capabilities and benefits offered by Quick Charge 3.0 to bring robust fast charging technology to all," said Alex Katouzian, senior vice president, product management, Qualcomm Technologies, Inc. "Quick Charge 3.0 addresses a primary consumer challenge with today's mobile devices in helping users restore battery life quickly and efficiently, and does so through leading technology and a robust ecosystem including leading device and accessory OEMs."
Quick Charge 3.0 is 100 percent backwards compatible with Quick Charge 1.0 and 2.0, so manufacturers shouldn't see any problem in implementing it in their devices. Quick Charge 3.0 supports a wide range of connectors, including USB Type-A, USB micro, USB Type-C, and proprietary connectors.
Quick Charge 2.0 is already supported by many certified smartphone accessories, including wall chargers, car chargers, battery packs and power controllers. The next-generation chargers should come with built-in support for Quick Charge 3.0.
A whole range of Qualcomm Snapdragon processors should also support the new Quick Charge 3.0, from the lower-end next-generation Snapdragon 430, to the more mid-range Snapdragon 617, 618 and 620, as well as Qualcomm's upcoming flagship chip, the Snapdragon 820.
