Qualcomm’s Quick Charge 4+ can charge batteries up to 15 percent faster

Qualcomm has unveiled its Quick Charge 4+ technology. According to Qualcomm, the technology for fast charging is able to charge batteries 15 percent faster than was already possible with Quick Charge 4. Devices should also become slightly less warm during charging.

In fact, Quick Charge 4+ is an evolution of Quick Charge 4 and a few improvements have been made. Faster charging is made possible by an improved dual charging function: the current is divided between two separate charging components, resulting in faster charging times and better heat distribution. The latter means that the temperature of devices is about 3 degrees lower during charging. Security has also been improved: the temperature of both the housing and the connector for the charging cable is monitored simultaneously. Quick Charge 4+ is compatible with Quick Charge 4, 3.0 and 2.0.

At the end of November 2016, Qualcomm announced the Quick Charge 4 technology together with the announcement of the Snapdragon 835. Quick Charge 4 made it possible to charge devices up to twenty percent faster compared to Quick Charge 3.0. According to the manufacturer, a device with Quick Charge 4 with a 2750mAh battery could charge from 0 to 50 percent in 15 minutes. Support for usb-c and usb-pd connections was also integrated.

The first smartphone to support Quick Charge 4+ is the Nubia Z17. This Chinese phone has now been announced and according to the manufacturer, the 3200mAh battery can be charged to 50 percent in 20 minutes. The device has a Snapdragon 835 in combination with 8GB of ram, is water resistant in accordance with the ip67 rating and has a dual camera on the back.
