The LG G5 supports Qualcomm Quick Charge 3.0 over USB Type-C . Let's see how well it works with other Qualcomm Quick Charge 3.0 chargers like the AUKEY PA-T16 Dual-Port USB Wall Charger.

The AUKEY PA-T16 Dual-Port USB Wall Charger is one of the first chargers in the market that supports Qualcomm Quick Charge 3.0. It's designed to be a wall charger and can support charging 2 devices at the same time by plugging them into its 2 USB Type-A ports.

Both USB Type-A ports support Qualcomm Quick Charge 3.0 which allows Qualcomm Quick Charge 3.0 enabled phones to rapidly charge using these power profiles: 6-6.5 volts @ 3 amps, 6.5-9 volts @ 2 amps, 9-12 volts @ 1.5 amps.

Here we have monitored the current and voltage levels at different stages of battery charging by using a current probe and oscilloscope. 

While charging with the battery at 0% charge, we can observe from the oscilloscope screenshot that voltage is 8.90V and maximum current is 0.51A.

With the battery at 25% charge, we can see from the oscilloscope screenshot that voltage is 8.92V and maximum current has decreased to 0.45A

When the battery is at 50% charge, we can see in oscilloscope screenshot that voltage is 8.92V and maximum current is 0.68A

Here is the oscilloscope screen shot with the battery at 75% charge which shows the voltage as 8.89V and maximum current as 0.60A.

The screenshot below shows the voltage and current when the battery is fully charged.

The following graph shows how the LG G5 draws different current levels (with voltage at 8.9 volts) as the battery charges from zero to full.  

The total power drawn by the LG G5 is generally about 4.9 to 6.1 watts which is less that what we saw with the Tronsmart Presto (click here for that review).  This results in the LG G5 taking around 1 hour 20 minutes to charge completely while the phone is powered on with the AUKEY PA-T16 Dual-Port USB Wall Charger.
