Quick Charge 3.0 

Qualcomm has been optimising its battery charging technologies for a long time and company is preparing to release the next generation Quick Charge 3.0.

Under the new system a phone can be charged from zero to 80 percent in about 35 minutes. This is quite an achievement. The Tesla car via super charger needs 40 minutes to get the car battery to 80 percent and these two charging standard work completely differently.

The Qualcomm Quick Charge 3.0 charges a 2750 mAh fast-charge battery (1.5C charge rate) using maximum power and thermal limit of 40C for all charging implementations. This is a realistic, down to earth testing scenario.

Quick charge automatically selects ideal voltage between 3.6V and 20V and can fine-tune the charging with 200 mV increments. The company claims that the Quick charge 3.0 is up to 38 percent more efficient than Quick Charge 2.0, up to 2X faster than Quick Charge 1.0 and up to four times faster than the conventional charging.

The charging time comparison is based on the data provided by QTI research using different charging standards to charge a phone from 0- 50 per cent.

The new charging standard is backwards compatibile with Quick Charge 1.0 and 2.0 and works with most USB chargers. It is connector-independent and works with USB Type-A, USB micro, USB Type-C, and other connectors.

Quick Charge 3.0 is available for Snapdragon 820, Snapdragon 620, Snapdragon 618, Snapdragon 617 and Snapdragon 430 SoCs. It will be up to phone manufacturers to include a Quick Charge 3.0 compatible charger, but we expect that most of them will go down that road, it simply makes sense to offer you a charger that charges your phone much faster than the conventional one.
