The Qualcomm Quick Charge 4 technology was introduced with the new flagship Snapdragon 835 SoC but the new updated Quick Charge 4+ version brings impressive improvements.
According to Qualcomm, Quick Charge 4+ brings three enhancements, Dual Charge, Intelligent Thermal Balancing and Advanced Safety Features. Of course, it also includes all the benefits of the original Quick Charge 4.
The Dual Charge was already present in earlier Quick Charge versions but now it has become more powerful. It includes a second power management IC in the device and divides the charge current allowing for both lower thermal dissipation and reduced charge time.
The Intelligent Thermal Balancing further enhances the Dual Charge feature and is engineered to move current via the coolest path autonomously. The Advanced Safety Features include built-in safety protocols which monitor both the case and connector temperature levels simultaneously and should protect against overheating and short-circuit or damage to the Type-C connector.
Based on Qualcomm's internal tests done on 2750mAh battery, the Quick Charge 4+ is up to three degrees Celsius cooler, up to 15 percent faster and up to 30 percent more efficient. To make it even better, the Quick Charge 4+ supports the same Snapdragon 835 chipset.
All is not that great as this is not a software update but rather a hardware update, which means that manufacturers will have to make certain changes in order to get the QC 4+ logo on their device.
Currently, the only device that supports the Quick Charge 4+ is the recently announced ZTE Nubia Z17 5.5-inch smartphone, which is based on the Qualcomm Snapdragon 835 SoC with 8GB of RAM, has a 3200mAh battery and QC 4+ logo.
We are quite sure that these further enhancements will push smartphone makers to make those changes and include Quick Charge 4+ on their smartphones.
