On July 27, 2020, Qualcomm announced the launch of Qualcomm Quick Charge 5, the fastest commercial charging technology for Android terminals. Compared with the previous generation platform, this platform not only provides unprecedented charging speed and efficiency improvements for smartphones, but also supports A series of new battery technologies, accessories and safety features. Quick Charge 5 is expected to be the first commercial fast charging platform that provides charging power of more than 100W for smart phones, which can help users to charge their phones from zero to 50% in only 5 minutes-almost the fastest mobile phone charging on the market. Program. Using Qualcomm Battery Saver battery health management and the new Qualcomm adapter power intelligent identification technology, Quick Charge 5 also achieves excellent charging efficiency and helps users extend the battery life of the terminal.
Ev Roach, Vice President of Product Management of Qualcomm Technologies, Inc. said: "Quick Charge 5, as our fastest charging solution with the widest range of applications, will allow consumers to enjoy longer periods of time without worrying about charging the terminal. Mobile experience. We are proud to be able to expand our technology portfolio and make 100W+ charging technology commercially available. At the same time, we also work closely with manufacturers to create industry-leading terminals to satisfy consumers The demand for a more convenient mobile experience."
Performance and efficiency
Built based on Qualcomm Technologies’ long-term leadership in the field of fast charging solutions, Quick Charge 5 is the industry’s leading fast charging ecosystem [According to Qualcomm Technologies Research’s Quick Charge terminal and accessories research report, it differs from other independent Compared with fast charging technology, the Quick Charge ecosystem is currently the largest fast charging ecosystem. ] The latest products. The performance of Quick Charge 5 is significantly improved compared to the previous generation platform. The charging efficiency is 70% higher than that of Quick Charge 4, and the output power is 10 times that of Quick Charge 1. [According to internal tests, the 4500mAh fast charge battery (1.5C charging rate) ) Carry out charging, all charging tests are carried out at the maximum power under the temperature limit of 40 degrees. The charging time is calculated by charging the battery capacity from zero to 50%. ]. The solution supports 2S battery and 20V power output.
The charging speed of Quick Charge 5 is 4 times that of the previous platform, setting a new benchmark for charging performance. In addition to supporting ultra-fast charging, Quick Charge 5 also supports excellent safety features-12-level voltage, current, and temperature protection, such as 25V USB input overvoltage protection and 30V or more external charging power control. Its operating temperature is also 10 degrees Celsius lower than Quick Charge 4. Quick Charge 5 supports dual/triple charging technology, adaptive input voltage, fourth-generation optimal voltage intelligent negotiation (INOV4) algorithm, Qualcomm Battery Saver battery health management, and new Qualcomm adapter power intelligent identification technology. The above technologies will be implemented together Maximize the charging efficiency, enhance safety and help extend the battery life of the user terminal.
To achieve the best performance of Quick Charge 5, Qualcomm Technologies also introduced the latest next-generation top power management integrated circuits (PMIC)-Qualcomm® SMB1396 and Qualcomm® SMB1398. By supporting 1SnP and 2SnP batteries, dual-channel wired and wireless charging, adaptive operation based on power input (3-level Buck and DIV/2) and scalability (using a master-slave architecture to provide higher power), Qualcomm SMB1396 and Qualcomm SMB1398 aims to achieve the highest charging efficiency of more than 98%. Not only that, they also support an input voltage above 20V operating mode to adapt to the highest power input for wireless and wired charging. Qualcomm SMB1396/SMB1398 is available now.
Ecosystem and wide range of uses
Quick Charge technology is the industry's leading fast charging method, covering more than 1,200 mobile terminals, accessories and controllers from car adapters to docking stations, and provides a unified charging ecosystem for mobile phones and laptops. Quick Charge 5 is an accessory that can handle various charging methods of mobile terminals. It is backward compatible with Quick Charge 2.0, 3.0, 4, 4+ and smartphones that have been launched on the market with the Qualcomm® Snapdragon™ mobile platform. The solution supports charging power of more than 100W, while using the same pin area as the previous generation 45W solution, reducing the need for users to purchase additional Quick Charge certified accessories for multiple terminals. The optimized Quick Charge 5 can make full use of USB-PD and Type-C technologies to meet the needs of future Android terminals. The compatibility of Quick Charge 5 with industry standards such as the USB Type-C protocol also helps users benefit from the native scalability of Quick Charge 5 and extend it to other terminals.
Zhang Lei, vice president and general manager of hardware research and development of Xiaomi mobile phone of Xiaomi, said: "Quick Charge solution is widely used in mobile terminal equipment. The latest generation of Quick Charge 5 not only has excellent charging ability, but also can intelligently extend terminal battery life and reduce heat dissipation. Output. Xiaomi has always been committed to the efficient popularization of new technologies, so that the experience enhancement brought by new technologies can be implemented quickly. In the future, more Xiaomi users will also enjoy the ultimate high-speed and safe experience brought by Quick Charge 5 technology."
Currently, Quick Charge 5 is sampling to customers, and it is expected to be available with commercial terminals in the third quarter of 2020. Snapdragon 865, Snapdragon 865 Plus and future top and high-end Snapdragon mobile platforms can support Quick Charge 5.
