We've mentioned before that some early USB-C cables aren't built to specification and could damage your hardware. Turns out, the same may be true of some phones that include a USB-C port and support Qualcomm's QuickCharge 3.0 technology.
As Google engineer Benson Leung explains, Qualcomm's new QuickCharge 3.0 technology is fundamentally at odds with the USB-C spec. You can read the technical details at the source link below, but the gist is that Qualcomm bends the rules in order to make its quick charging technology possible. Currently, the LG G5 and the new HTC 10 both employ these contradictory technologies at the same time. Quick chargers already come with their own set of downsides to begin with. While they may be worth the risk normally, it might be worth considering the dangers of conflicting specs in your device.
