The idea is to offer the same speeds as Quick Charge 4+, but with compatibility for an inexpensive USB Type-A cable. The first device to support the charging technology is the newly-announced Xiaomi Mi 10 Lite Zoom. In fact, the smartphone supports both Quick Charge 3+ and Quick Charge 4+. The first chipsets to support it will be the Snapdragon 765 and 765G, which already support Quick Charge 4+, so it's not really about lower-cost devices. But OEMs could still offer lower-cost peripherals and chargers, which could bring down the cost of the package.
Qualcomm revealed the aim of QC3+ is to bring a fast-charging solution to more affordable smartphones. Compared with previous generations, it will be 35 percent faster and up to nine degrees cooler. The standard will work over USB-A to USB-C cables and will work with accessories that support scalable voltage from Quick Charge 4.
The new single IC design measn the phones won’t need an OVP (over-voltage protection) chip, a sense resistor, or others. Quick Charge 3+ will have support both for wireless and wired charging, and it will even work when used simultaneously.
