Qualcomm Announces Quick Charge 3+ With USB Type-A Support

Qualcomm quick charge 3

Qualcomm has just announced a new version of its fast-charging technology for smartphones. The new Quick Charge 3+ is aimed to bring a faster wired charging solution to smartphones at a lower price point.

Quick Charge 3+ will be available first on Qualcomm Snapdragon 765 and Snapdragon 765G chipsets. Other Snapdragon platforms will get support for the new technology later this year.

Xiaomi’s Mi 10 Lite Zoom is the first smartphone to support Quick Charge 3+. The handset, which is powered by the Snapdragon 765G, was launched in China earlier this week.


This device also supports Qualcomm’s Quick Charge 4+, making it the world’s first smartphone to support both charging technologies. Qualcomm isn’t telling which other devices would be employing Quick Charge 3+.

Quick Charge is Qualcomm’s proprietary fast-charging solution for smartphones running its Snapdragon SoCs. The company licenses multiple versions of the technology to phone makers. It claims Quick Charge to be the biggest fast-charging ecosystem in the world with 1000+ accessories and devices worldwide.

Quick Charge 4+, its most advanced fast-charging technology yet, was announced back in 2017. It has now announced Quick Charge 3+ with similar benefits as Quick Charge 4+ but at a lower price. The new technology brings significant improvements over Quick Charge 2.0 or 3.0, the fast-charging technology that many lower-cost smartphones currently employ.


Key features of Qualcomm Quick Charge 3+

Qualcomm’s Quick Charge 3+ promises a 35 percent faster charging compared to previous generations. The new technology is capable of charging a smartphone from 0 to 50-percent in just 15 minutes.

That’s identical to the speed offered by Quick Charge 4+. Qualcomm also promises the new technology to keep the device 9°C cooler than the previous generation offerings.

While Quick Charge 4+ requires a USB-C connector, Quick Charge 3+ is compatible with the inexpensive USB-A connector as well. It supports standard USB Type-A to Type-C cables as well as accessories that support scalable voltage with 20mV steps from Quick Charge 4.


The new fast charging technology is backward compatible with previous-generation Quick Charge devices. So accessories based on the new technology can offer similar charging speed to older devices as well. Quick Charge 3+ also offers integrated cable power identification.

Support for new PMICs such as SMB1395 and SMB1396 means Quick Charge 3+ eliminates the need for external components such as over-voltage protection chip, a sense resistor, and others. Quick Charge 3+ also supports both wired and wireless inputs.

Qualcomm’s idea behind Quick Charge 3+ is clearly to offer low-cost fast-chargings solutions. USB Type-A support means OEMs could offer lower-cost peripherals and chargers with their phones, making for a less expensive package.
