Quick Charge 5 is a commercial rapid charging technology for Android devices, and will be the world's first commercial charging platform for smartphones with a maximum output of over 100 W. Since the maximum output of Quick Charge 4 announced by Qualcomm in 2016 was 27 W, it means that the maximum output has improved by almost 4 times.
According to Qualcomm's announcement, Quick Charge 5 has achieved 70% efficiency improvement compared to Quick Charge 4, and it is possible to charge smartphones up to 4 times faster. When a user charges a device with a Quick Charge 5 compatible adapter and device, it can charge a device with 0% battery remaining to 50% in just 5 minutes, and it takes only 15 minutes to fully charge Qualcomm Insists.

Quick Charge 5 uses the power supply standard ' USB Power Delivery (USB-PD) ' that uses USB Type-C, and Programmable Power Supply (PPS) that is an optional high-speed charging standard of USB-PD. PPS is a system that optimizes the power supplied from the charger to the device by changing the voltage and current in small steps, and it enables high-speed charging while minimizing the energy that is lost as heat. At the time of Quick Charge 4, it was compliant with USB PD-PPS, but it was not actively using it as a voltage regulation protocol, Ananda Tech of technology media pointed out.
By using USB PD-PPS, in Quick Charge 5, the voltage conversion work will be done by the adapter side instead of the power management IC (PMIC) inside the smartphone, and it is possible to suppress the conversion loss and the resulting heat generation of the smartphone. The heat generated when charging with Quick Charge 5 is about 10 degrees lower than with Quick Charge 4.
Quick Charge 5 is also backwards compatible, allowing you to quickly charge your Quick Charge 5-compatible device with your previous Quick Charge-compatible charger and charge your previous Quick Charge-compatible device with your Quick Charge 5-compatible charger It is also possible to do. High-speed charging with Quick Charge 5 is only possible when both devices and chargers support Quick Charge 5.
Quick Charge 5 charges devices very fast, but Qualcomm argues that it also takes safety precautions into consideration. Quick Charge 5 is said to have 12 individual voltage, current, and temperature protection features, such as USB input overvoltage protection at 25V and external power control over 30V.
Ev Roach, Vice President of Products at Qualcomm Technologies, said, ``Our fastest and most versatile charging solution, Quick Charge 5, allows consumers to run devices for hours without worrying about how long they need to recharge. It makes it possible to have fun.' ``In the future more Xiaomi users will enjoy a faster, safer and better charging experience with Quick Charge 5,'' said Zhang Lei, Xiaomi's Mi Phone Vice President and Hardware R&D General Manager. That said, it suggests adding Quick Charge 5 to Xiaomi smartphones.
Qualcomm said Quick Charge 5 will be available in commercial devices coming in the third quarter of 2020 and will be supported on the Snapdragon 865, 865 Plus, and future Snapdragon mobile platforms.
