The Nubia Z17 by ZTE comes equipped with a USB Type-C connector that supports quick charging over USB Power Delivery or Qualcomm Quick Charge through Qualcomm Quick Charge 4+ technology. Let's see how the phone charges with a USB Power Delivery enabled charger like the GoPro Supercharger when directly connected over the USB Type-C port.
The GoPro Supercharger can be seen to constantly offer the following USB Power Delivery based charging profiles: 15 watts (5 volts @ 3 amps), 16.5 watts (5.5 volts @ 3 amps), and 20 watts (12 volts @ 1.67 amps) to the Nubia Z17 at zero charge.
After a while the GoPro Supercharger accepts the Nubia Z17's request to pull 15 watts (5 volts @ 3 amps).
While the GoPro Supercharger charges the Nubia Z17 from 0% battery, we can see that the phone pulls around 15 watts (5 volts @ 3 amps) from the charger. However it takes more than 10 seconds for the charger to finally charge the phone at 15 watts (5 volts @ 3 amps) over USB Power Delivery.
