I have tried an assortment ranging from 1amps to 2 amps (Apple, Motorola, Samsung, generic). It appears though I am wrong and it is not Moto's fault, but the Qualcomm 2.0 quick charge spec. For a charger to be assured to not charge at USB speed, it needs to be "Qualcomm 2.0 Quick Charge" certified. Now, does that mean it will only charge super fast, or super slow? No normal in between? Yes, 102 degrees is too warm IMO. Perhaps if I did not used to work in this industry and our customer service and quality teams constantly "negotiate" with customers over these things I would be Ignorance is Bliss. I turned it off on the Note 4 as well.
