Qualcomm Quick Charge 4+ provides 15% faster charger time

Dual Charge: already an option in earlier versions, but now more powerful, Dual Charge includes a second power management IC in the device. Charging a device via Dual Charge divides the charge current, allowing for lower thermal dissipation and reduced charge time.

  • Intelligent Thermal Balancing: a further enhancement to Dual Charge, intelligent thermal balancing autonomously moves current via the coolest path, eliminating hot spots for optimized power deliver.
  • Advanced Safety Features: Quick Charge 4 already includes rigorous built-in safety protocols. Quick Charge 4+ goes one step further with simultaneous monitoring of both the case and connector temperature levels. This extra layer of protection wards against overheating and short-circuit or damage to the Type-C connector.

With Dual Charge, Intelligent Thermal Balancing, and Advanced Safety Features incorporated in a device design, that device has the potential to charge up to 15 percent faster, or 30 percent more efficiently when compared to Quick Charge 4.

Accessories such as wall adapters, car chargers, portable battery banks, and USB hubs can also qualify for Qualcomm Quick Charge 4+ designation. Such an accessory will include backward compatibility with Quick Charge 3.0 and Quick Charge 2.0. Having a 4+ certified accessory will help ensure that your existing Quick Charge 3.0 and 2.0 enabled devices will work with the latest commercially available adapters.

Manufacturers meeting the device or accessory requirements can use the 4+ logo on their products. Qualcomm Technologies will also include each of these in the Quick Charge certified device list so consumers will have an easy means to find qualifying products. Remember, not all power adapters are created equal. That’s why Quick Charge accessories go through a rigorous certification process to ensure they meet the stringent requirements set forth by UL.

The first device to include Quick Charge 4+, the ZTE nubia Z17, was announced this morning. The nubia Z17 is one powerful smartphone featuring, in addition to Quick Charge 4+ and a 3200mAh battery, the Snapdragon 835 mobile platform with an impressive 8GB RAM and 128GB memory, 23+12 megapixel dual rear camera, and a 5.5” FHD frameless display.

With Quick Charge 4+, Qualcomm Technologies once again shows our leadership in charging technology. Since the first products came out over 4 years ago, Quick Charge technology has been included in over 130 mobile devices and 475 accessories, making it the most popular fast charging technology available by a wide margin. Quick Charge 4+ continues the fast charging innovation, providing design flexibility for manufacturers, and a diverse ecosystem of certified products for consumers. Be sure to look for Quick Charge 4+ in your next mobile device.

Quick Charge 4+ also includes a special program for device and accessory manufacturers who design products with the aforementioned features.
