Qualcomm announces faster phone charging tech

Friday, 31 Jul, 2020

The world's largest mobile chipmaker Qualcomm today announced the latest iteration of its fast charging technology, dubbed as the Quick Charge 5. Fast wireless charging is also supported, though how much faster it will be with Quick Charge 5 will vary based on the type of wireless charging coils manufacturers use in their devices.Qualcomm's new Quick Charge 5 logo. The company said Quick Charge 5 is already sampling with its customers and is expected to show up "in commercial devices in Q3 2020". Apart from the super quick charging efficiency, the technology has also been claimed to be 10 percent cooler and 70 percent more efficient in comparison to its previous version. According to the company, a 4,500mAh battery can be charged from flat zero to 50% in just 5 minutes. Adding more on the specifications Qualcomm has stated that if right cable is used with a phone supporting Quick Charge 5.0, more than 100W of power would be delivered to the charging circuit of the device.

Interestingly Anandtech notes something not mentioned in the Qualcomm press release: Quick Charge 5 is leveraging the existing USB Power Delivery Programmable Power Supply (PD-PPS) standard (a subset of the existing USB-C PD spec). Its smart identification of adapter capabilities helps it deliver the right amount of capacity to nearly every device since it is backwards suitable for previous generations of Quick Charge and devices powered by Snapdragon chipsets.

We have all been acquainted with Brief Cost and its different implementations in excess of the many years, innovating beyond the classical USB ability delivery restrictions of 5W in excess of 7 years ago.

The fifth incarnation of the tech can fully charge a phone in that time, Qualcomm claims. For those companies that rely on Qualcomm's Quick Charge they will now have the opportunity to compete with Qualcomm introducing a faster Quick Charge overnight. PD was mentioned in terms of compatibility in the Quick Charge 4 announcement, so perhaps the two are diverging again.

Quick Charge 5 incorporates 12 separate voltage, current and temperature protections. That means if you have an older Quick Charge-compatible smartphone, you'll be able to use a Quick Charge 5 power adapter with it.

The big story to know is the 100W+ charging speeds that Quick Charge 5 is capable of. Qualcomm says Quick Charge 5 is the "first commercially viable" standard to support over 100W.

To ensure device safety, Quick Charge 5 also includes eight levels of voltage protection, three levels of current protection, three levels of thermal protection, and three levels of timer protection.
