How Long It Takes for the Motorola Moto G6 Phone to Fully Charge with the Newer 27W Verizon USB-C (Type C) Wall Charger Over USB Power Delivery

The Motorola Moto G6 can use both its own TurboPower branded charging scheme as well as USB Power Delivery 2.0 technology to charge quickly over the USB Type-C interface. With TurboPower the phone took around 109 minutes to charge to full as seen here but when used with the third party Verizon USB-C (Type C) Wall Charger, it needed about 130 minutes to complete entire charging over USB Power Delivery. Note that this Verizon USB-C (Type C) Wall Charger is a newer version of the Verizon USB Type-C Wall Charger with Fast Charge Technology which we also tested previously with the Moto G6 in this review.  

After plugging in the Moto G6 with a fully discharged battery to the Verizon USB-C (Type C) Wall Charger, we could initially see current being pulled as the voltage started off near to 5 volts. After the first 3 minutes, the voltage went down slightly to about 4.7 volts while the current pulled started to decrease from around 2.8 amps down to 2 amps when approaching 40 minutes of charging. During this period the phone drew power to charge from 13.2 watts (4.7 volts @ 2.8 amps) to 9.4 watts (4.7 volts @ 2 amps). Over the next 40 minutes the current continued to reduce further down to about 1.4 amps while the voltage stayed along a 4.7 volts rail for about 6.6 watts charging. After the phone has charged for 97 minutes, the voltage went up a bit to reach 4.9 volts but the current began to ramp down quickly to under .3 amps. The current then dropped to almost zero in the last few minutes of charging once the battery has filled up. Click here to download the trace captured by the GRL-A1 power analyzer to see more details on the entire power charging cycle.

The Motorola TurboPower based charger was able to achieve up to 16W charging through a rapid current modulation approach (probably to reduce heat and improve battery life) while the Moto G6 pulled less current from the Verizon USB-C (Type C) Wall Charger and also pulled current at a steady rate, resulting in slower charging.
