Qualcomm has introduced Quick Charge 5, the latest fast charging standard from the company. It is the successor to Quick Charge 4 and brings some big promises. The new quick charging scheme comes with the ability to fully charge a phone in just 15 minutes whereas, charge from 0-50% in 5 minutes with 100W+ charging power.
Quick Charge 5 is a massive jump from a Quick Charge 4 which was introduced three years back. And Qualcomm is calling it the “World’s Fastest Commercial Charging Solution”. This tech will change how your phone charges. The above numbers are based on 4,500mAHh stacked into two 2,250mAh cells using dual charging solution. According to Qualcomm this architecture is up to 70% more efficient than Quick Charge 4 keeping the battery 10-degree Celsius cooler. Further, Triple charge is also supported.
Quick Charge 5 is using the existing USB Power Delivery Programmable Power Supply (PD-PPS) standard. It’s also backward computable with QC2, QC3, QC4 and QC4+ at the fastest speed those chargers can provide. It also works with USB PD based devices as well as iPhones. Likewise, QC5 charging brick will also work with laptops.
Qualcomm claims it to be safer as it includes 8 levels of voltage protection, 3 levels of current protection, 3 levels of thermal protection and 3 levels of timer protection, incorporating USB-input overvoltage protection at 25V and extreme power controls beyond 30V
Furthermore, Qualcomm’s new “Smart Identification of Adapter Capabilities” will monitor and verify the actual, instead of just trusting, limits of a connected charger to adjust current, power and voltage behavior keeping an eye on thermals.
Quick Charge 5 Availability
Quick Charge 5 is supported by Snapdragon 865 and 865 Plus and future upcoming high tier Snapdragon Mobile Platforms. However, it requires charge controller chips. Qualcomm has announced two charge controller chips – SMB1396 and MSB1398. Both the chips supports wired and wireless input and can be used with 1 cell and 2 cell batteries. Dual cell design can offer 50W charging whereas single cell will offer 45W charging.
Xiaomi will be the first brand to leverage this technology in upcoming months. Moreover, other brands will also integrate this charging solution as tons of companies uses Qualcomm’s processor and modem, QC5 will be easily compatible to those devices.
