Qualcomm enables mobile Quick Charge in 35 minutes

Quick Charge 3.0 will be available on the Qualcomm Snapdragon 820 processor and in mobile devices next year.

By CBR Staff Writer

Qualcomm Technologies has introduced the third version of its Quick Charge technology, which it says
can charge a typical phone from zero to 80% in just 35 minutes.

Quick Charge 3.0 is expected to be available on the Qualcomm Snapdragon 820 processor and in mobile devices next year.

Apart from the Snapdragon 820 processor, Quick Charge 3.0 will also be available on the Snapdragon 620, 618, 617 and 430 platforms.

The third version features Intelligent Negotiation for Optimum Voltage (INOV), a new algorithm developed by Qualcomm Technologies. It is designed to be about 38% more efficient than the second version.

When used with Qualcomm’s new parallel charging configurations, Quick Charge 3.0 can help enhance fast charging up to 27% or lower power dissipation by around 45%, compared to Quick Charge 2.0.

The second version provides four charging voltages at 5V, 9V, 12V and 20V. The third version offers flexibility with 200mV increments from 3.6V to 20V.

It enables the phone to request enough voltage to reach the desired charge current, which will minimise losses, increase efficiency, and enhance thermal performance.
