There are multiple versions of the technology that Qualcomm licenses to OEMs, with the foremost advanced being Quick Charge 4+. Today, Qualcomm introduced a replacement version of its Quick Charge technology: Quick Charge 3+. With Quick Charge 3+, Qualcomm aims to bring its fast wired charging technology to smartphones at a lower cost point. This new technology is meant to function an upgrade for devices using Quick Charge 2.0 or 3.0 without significantly increasing the worth to implement. Qualcomm says the new technology allows for charging a tool from 0-50% in quarter-hour, which is 35% faster than the previous generation (presumably Quick Charge 3.0). Qualcomm also says that their new charging technology can keep a tool 9°C cooler than before when charging. These numbers are supported reference data from one IC and an “appropriate board/battery design,” though Qualcomm didn’t reveal more details on the setup they wont to produce this data.
Quick Charge 3+ supports standard USB Type-A to USB Type-C cables also as accessories that support scalable voltage with 20mV steps from Quick Charge 4, a feature that Qualcomm calls Intelligent Negotiation for Optimum Voltage (INOV). Quick Charge 3+ is backward compatible with older Quick Charge versions, so new accessories supported the new standard can still fast-charge older devices.
This technology is already supported by the Qualcomm Snapdragon 765 and Snapdragon 765G SoCs but also will be supported on new Snapdragon mobile platforms which will be introduced later this year. Xiaomi’s new Mi 10 Lite Zoom, also referred to as the Xiaomi Mi 10 Youth Edition in China, is that the first device to support both Qualcomm Quick Charge 3+ and Quick Charge 4+ simultaneously. we will expect more devices launching later this year to feature Qualcomm’s QC 3+.
