Hi Mathieu, thanks for the reply. When you were experiencing the disconnecting above 80% charge, were you using the USB-C cable that came with our docking station?
Interesting regarding the behavior with the cable that may be from the Nexus 6P. Not all USB-C cables have the same functions so it can be difficult to say if a specific one will work without examining the specifications online, and even then we can’t always guarantee it would work with our dock. The USB-C cables must support the power delivery, video and USB standards for USB-C and why we generally recommend using the cable that comes with the dock for best performance.
