<p align="center"> </p><p><p>One of the other features that was announced for multiple Snapdragon SoCs at the 3G/LTE Summit in Hong Kong was Quick Charge 3.0, which will be supported on the Snapdragon 820, 617, and 430.</p>
<p>The latest iteration of Qualcomm's rapid charging technology, Quick Charge 3.0 is said to enable up to 27% faster charging over QC 2.0 or up to 38% more efficient. Relative to QC 1.0, charge speed doubles. This is done by using an algorithm that Qualcomm calls Intelligent Negotiation for Optimum Voltage, which allows for selection of appropriate voltage for various device states while charging. Rather than a number of fixed voltage settings, QC 3.0 can scale from 3.6 to 20V in 200 mV increments and will work over USB, including new connector designs like USB Type-C as the USB protocol is not the same as physical connector design. QC 3.0 will be available for vendors to implement now, and it’s likely that we’ll see phones with support for this new fast charging standard appear early next year.</p>
