How Well USB Power Delivery 3.0 Works Between the LG G7 ThinQ and the AUKEY PA-Y10 Amp PD 3.0 USB-C Wall Charger
By supporting USB Power Delivery 3.0 over USB Type-C through Qualcomm Quick Charge 4+ technology, let's see how well the LG G7 ThinQ phone charges with the equivalent USB PD 3.0 based third party AUKEY PA-Y10 Amp PD 3.0 USB-C Wall Charger. The Aukey charger comes with a 46W USB PD 3.0 Type-C port supporting both standard PDO (Power Data Objects) protocol and PPS (Programmable Power Supply) which we used to connect the LG phone on a fully depleted battery.
Note Qualcomm Quick Charge 4+ also enables PPS and Qualcomm Quick Charge 3.0 technology over USB Type-C on the LG G7 ThinQ.
The entire charging cycle took about 140 minutes as observed from the trace captured by the GRL-A1 power analyzer. It's also worth noting that an almost similar duration was also seen here using the phone's own LG 16W Qualcomm Quick Charge charger. When plugged in to the Aukey charger, the LG G7 ThinQ started off 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. As the voltage dropped back down to a 5 volts rail, the phone kept on pulling quick changing current to charge at within a 0-15 watts power band. Charging then became more stable after about 80 minutes as the current began to ramp down to near .1 amps when almost reaching full charge on the battery.
The LG G7 ThinQ uses very aggressive power management schemes even for USB Power Delivery such that even while the charger is connected to the phone, the current repeatedly goes down close to zero at repeated intervals.
