Using the Qualcomm Quick Charge 4+ certified Razer 24W Charger that ships with the Razer Phone, we observed in this review the charger was able to provide 17 watts charging to the Xiaomi Mi 6 phone, both supporting USB Power Delivery 3.0 technology. Here we see overall it took a total charging time of nearly 118 minutes for the Mi 6 to get fully charged.
We again re-connected the Razer 24W Charger to the Mi 6 with a fully discharged battery over USB Type-C, where the phone started off pulling around 17 watts of power from the Razer charger. After the first 20 minutes of charging, the phone kept on using Augmented PDO's to request the charger to ramp up from 5 volts to 11 volts as the current level dropped to almost half and rapidly changing.
Once the battery has charged for 50 minutes, the power charging reset resulting in both voltage and current to decrease for charging to drop to around 6 watts and further down to about 1 watt over a duration of 1 hour and 58 minutes. The current pulled eventually settled at 0.2 amps as the battery was almost full.
