The Nubia Z17 was released last week in China as the world's first smartphone to incorporate Qualcomm's new Quick Charge 4.0+ technology. However, it appears that this particular achievement has been hindered by Nubia itself; according to Chinese media outlets, the Nubia Z17 does not contain a Quick Charge 4.0+ charger inside the box, effectively negating any benefits users may have had from Qualcomm's latest charging solution.
Quick Charge 4.0+ was introduced by Qualcomm last week as an enhanced version of Quick Charge 4.0, and the company confirmed that the technology will be adopted by smartphone manufacturers starting mid-2017. It so happened that the Nubia Z17 was the first smartphone with Quick Charge 4.0+ onboard to hit the shelves in China, and the smartphone's launch was mentioned by Qualcomm itself in its announcement of the new charging tech. However, sources in China recently revealed that the Nubia Z17 includes a Quick Charge 3.0 charger in the retail box, as opposed to a new charger supporting Quick Charge 4.0+ or at least Quick Charge 4.0. Moreover, there don't seem to be any Quick Charge 4.0+ chargers available for purchase separately, meaning that while the Nubia Z17's internal hardware does support Qualcomm's latest fast charging technology, there is currently no way to take advantage of it. It remains to be seen whether Nubia will release a Quick Charge 4.0+ charger eventually, or if accessory manufacturers will launch such devices before the Chinese phone maker does.
As for what Nubia Z17 owners miss out on until an updated charger will be available, Quick Charge 4.0+ revolves around three main additions to Quick Charge 4.0, namely Dual Charge, Intelligent Thermal Balancing, and Advanced Safety Features. Qualcomm claims that a device incorporating all of those features has the potential of charging up to 15-percent faster and be 30-percent more efficient compared to devices supporting only Quick Charge 4.0. The Nubia Z17 was launched last week featuring a 5.5-inch IPS LCD display with a resolution of 1920 by 1080 pixels, a Qualcomm Snapdragon 835 system-on-chip, 6GB / 8GB of RAM coupled with 64GB / 128GB of onboard storage, and a dual camera setup comprised of a 23-megapixel sensor and a 12-megapixel one, in addition to featuring a 16-megapixel front camera and a 3,200mAh battery.
