Qualcomn Quick Charge 3.0 ls Coming, Explanation and First Supported Device Leaked

HI Guys

We are excited to learn Qualcomm just released the next-generation fast charging technology today : Quick Charge 3.0.

quick charge 3.0

Quick Charge 3.0 is the third generation of this technology and is the first of its kind to employ Intelligent Negotiation for Optimum Voltage (INOV), a new algorithm developed by Qualcomm Technologies, designed to allow portable devices the ability to determine what power level to request at any point in time for optimum power transfer, while maximizing efficiency. With Quick Charge 3.0 you can charge a typical phone from zero to 80 percent in about 35 minutes compared to conventional mobile devices without Quick Charge that may typically require almost an hour and a half.

With, INOV and other advancements, Quick Charge 3.0 is designed to be up to 38 percent more efficient than Quick Charge 2.0, while also implementing additional steps to help protect battery cycle life. Additionally, when used with Qualcomm Technologies’ latest, advanced parallel charging configurations, Quick Charge 3.0 can:

  • Help improve fast charging up to 27% or reduces power dissipation by up to 45% when compared to Quick Charge 2.0.
  • Charge up to 2x faster than Quick Charge 1.0

Quick Charge 3.0 will be featured as an option on select Qualcomm® Snapdragon processors, including Snapdragon 820, 620, 618, 617 and 430, and is anticipated to appear in mobile devices launched next year. Qualcomm Snapdragon processors are products of Qualcomm Technologies, Inc.

Additional improvements offered by Quick Charge 3.0 include enhanced flexibility over Quick Charge 2.0, notably in terms of charging options. While Quick Charge 2.0 offers four charging voltages at 5V, 9V, 12V and 20V, Quick Charge 3.0 provides flexibility with 200mV increments from 3.6V to 20V. This allows the phone to request just enough voltage to reach the desired charge current, resulting in minimized losses, increased efficiency, and improved thermal performance.

Quick Charge 3.0 also maintains forward and backward compatibility with previous versions of Quick Charge as well as with connectors, including USB Type-C, as well as the same ultra-fast charging speed, cable independence offering OEMs several options, and UL certification to help meet quality and safety standards.

Official Video from Qualcomm:


From the above video,we can see Qualcomm use the Xiaomi smartphone (might be Xiaomi Mi 5) to demonstrate the Quick Charge 3.0, so Xiaomi Mi 5 might be the first device which support Quick Charge 3.0)

Xiaomi 5


And Tronsmart are honored to announce, we will be the first brand to release the OEM Quick Charge 3.0 Chargers. Actually, Our design house have worked with Power Integrations for months for the Quick Charge 3.0 solutions. Power Integrations will release the new Power Controllers ( in QC2.0, they use the CHY100) for Quick Charge 3.0. and we have used our popular WC1Q wall charger to test the QC3.0 demo ( and the testing demo pcba board is offered by Power Integrations official, because we test with no-load, so the current don’t show up, we just show the volt change)

Here are some of our test result:

2015-09-01 142017

2015-09-01 142107 2015-09-01 142108

and like Qualcomm said Quick Charge 3.0 provides flexibility with 200mV increments, We can see the volt change every 0.2V . and what’s more, we find the following volt range has the best efficient :

2015-09-01 142123 2015-09-01 142124 2015-09-01 142126 2015-09-01 142127 2015-09-01 142130



We have all of our testing photos uploaded, you can download here:


So In our understanding, The most important features which Quick charge 3.0 bring to us is improving the charging efficiency, With the high charging efficiency, We get faster charging speed, less heat during charging, and much more safety for battery. Big step the charging industry!

We will release the Quick Charge 3.0 chargers this month for testing, If you are interested, please leave comment below, we will pick up the some lucky guy to test the newest qc3.0 technology! Don’t worry about no device support, It can backward compatibility with Quick Charge 2.0 If it detect your device don’t support QC3.0,It will still give you 5v/9v/12v volt. and we will see more device which support QC3.0 soon.
