Qualcomm developed new enhancements and created a special program with new features for the Quick Charge 4 – making it Quick Charge 4+.
When Quick Charge 4 was announced, it boasted faster charging, allowing a device to go from empty to 50 percent in just 15 minutes. Improved from its predecessor, Qualcomm added new technologies designed to further extend battery cycle life, enhance safety, and expand charging intelligence. These features come standard with a device that includes Quick Charge 4. Since then, Quick Charge 4 has been included in over 130 mobile devices and 475 accessories.
On the mobile device side, Quick Charge 4+ includes all the benefits of Quick Charge 4, plus three enhancements. Manufacturers get the 4+ designation by including all three:
- Dual Charge: already an option in earlier versions, 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: intelligent thermal balancing is engineered to move current via the coolest path autonomously, eliminating hot spots for optimised power delivery
- Advanced Safety Features: designed to monitor both the case and connector temperature levels simultaneously. This extra layer of protection helps ward against overheating and short-circuit or damage to the Type-C connector.
With the additional 3 components, devices 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.
The first device to include Quick Charge 4+ support is the nubia Z17. The nubia Z17 features a 3200mAh battery, the Snapdragon 835 mobile platform with 8GB RAM and 128GB memory, 23+12 megapixel dual rear camera, and a 5.5” FHD frameless display.
