Samsung's Adaptive Fast Charging Charger Can Charge the Moto X4 Phone But Slowly

The Samsung Adaptive Fast Charging Charger adopts Samsung's 15 watts Adaptive Fast Charging (AFC) scheme to quickly charge Samsung phones  but the charger can also power other phones like the Moto X4 which supports both USB Power Delivery and Lenovo’s branded TurboPower based quick battery charging technology over USB Type-C.

With a USB Type-C to Type-A cable connected in between the Samsung Adaptive Fast Charging Charger and the Moto X4 at 9% charged, we see how charging looks like through the Granite River Labs GRL-USB-PD-A1 power analyzer.

Initially, the voltage starts off at about 5.1 volts at which the phone begins pulling quick changing current of mostly around 1.6 amps while turned on. Both voltage and current then smooth out for charging to stabilize at around 7.6 watts (5.1 volts @ 1.5 amps).

This charging seems to adhere to the 7.5 watts (5 volts @ 1.5 amps) based USB Battery Charging 1.2 scheme which is slower than more modern fast charging schemes as well as when using the phone's own Motorola TurboPower based charger.
