Late last year, Qualcomm announced its flagship Snapdragon 835 processor along with Quick Charge 4.0, its newest fast charge technology. Fast-forward seven months and Qualcomm’s got an updated version of Quick Charge 4.
The new Quick Charge 4+ is now official. It can charge up to 15 percent faster than Quick Charge 4.0, says Qualcomm, while also being 3 degrees Celsius (about 5 degrees Fahrenheit) cooler. Here’s the rundown on the tweaks that enable those improvements in Quick Charge 4+:
- 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 is engineered to move current via the coolest path autonomously, eliminating hot spots for optimized power delivery
- Advanced Safety Features: Quick Charge 4 already includes rigorous built-in safety protocols. Quick Charge 4+ goes one step further and is 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.
The first device to support Quick Charge 4+ is the new ZTE Nubia Z17, which was just announced this week. The ZTE Nubia Z17 is packing a 5.5-inch 1920x1080 display, 8GB of RAM, 128GB of storage, a Snapdragon 835, and a 3200mAh battery.
