Qualcomm Quick Charge Benefits

Reduced Charge Time

Charges up to 75% faster than conventional technology. Less charge time means more time being truly mobile.

Full Compatibility

Designed to enable backward/forward compatibility and interoperability enables true universal charging. No need to replace existing power cords or adapters.

Safety & Reliablility

Engineered with advanced safety and reliability features.

While Quick Charge 1.0 rests in the devices only, Quick Charge 2.0 resides in both the device, offered as a standalone IC solution or as part of the PMIC (power management integrated circuit) of Snapdragon™ 800 processors, and in the AC/DC wall charger.

Just how fast is Qualcomm Quick Charge? See how Quick Charge 1.0 and 2.0 compare against conventional USB charging using a 3300mAh battery.
