Nexus 6p won't charge on included charger Not sure what to make of this one.  I have two nexus 6P's.  


Phone A won't charge on included charger+cable+outlet, however it does charge on a variety of other chargers I have access to.  
Phone B charges on the same charger+cable+outlet Phone A won't charge on


Any ideas as to what's wrong and how to resolve?

Edit: From comments Both phones charging on the same setup (charger/cable/outlet).
The uncooperative phone started charging again on the included charger setup after a reboot.
