Qualcomm has introduced Quick Charge 5 (QC5) fast charging technology for flagship mobile devices based on Snapdragon 865, Snapdragon 865 Plus and later processors with high-capacity batteries. According to the manufacturer, the QC5 is up to 10 times faster than the original Quick Charge 1, introduced in 2013, and up to 4 times faster than the Quick Charge 4, which hit the market in 2017.
Using the Quick Charge 5 technology allows you to create chargers on its basis with a power of more than 100 W. According to Josh Warner, head of product management for charging technology at Qualcomm, the new Quick Charge 5 standard is “the fastest commercial charging standard . “
The main feature of the new technology is its ability to charge a 4500 mAh battery up to 50% in just 5 minutes. At the same time, a charger based on this standard will be able to charge such a battery up to 100% in just 15 minutes. In addition, the new technology offers an increased level of efficiency (up to 70% higher than Quick Charge 4), which translates into a 10 ° C lower heating rate of the battery during charging. For Quick Charge 5, Qualcomm has announced 17 different protection technologies, including overvoltage and overheating protection.
To maximize the performance of Quick Charge 5 technology, Qualcomm encourages mobile device manufacturers to use dual batteries in their gadgets. This will ensure the maximum charging rate of the batteries and at the same time minimize the level of heating during the charging process.
The manufacturer also claims Qualcomm Battery Saver technology is designed to minimize battery degradation during such fast charging. At the same time, the use of their own similar technologies from manufacturers of mobile devices (for example, the same Battery Care from Sony) is clearly not superfluous.
The first Quick Charge 5 chargers are expected to arrive in the third quarter of 2020. Qualcomm also introduced the new SMB1396 and SMB1398 power controllers to support similar products. They can be used to create both wired and wireless chargers with an efficiency higher than 98%.
