Qualcomm intros Quick Charge 4+ charging technology
Qualcomm has introduced their new charging technology for newer high-end smartphones – the Quick Charge 4+.
The Quick Charge 4+ is a follow up to the Quick Charge 4 technology that Qualcomm introduced in November 2016. QC4+ has all the benefits of QC4 plus three enhancements.
• 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.
Qualcomm says that manufacturers can use the 4+ designation if their device or accessory meets the requirements which include the three enhancements mentioned above.
The first device to include Quick Charge 4+ support is the Nubia Z17.
