LG’s latest flagship Android smartphone, the G6, is yet another new phone to come with a USB Type-C port. Sporting a Qualcomm Snapdragon 821 SoC, this USB-C port also supports fast charging based on Qualcomm’s Quick Charge 3.0 tech. With the bundled QC3 adapter, the phone will charge at a maximum 9V at 1.8A (16.2W).

But not all adapters support Quick Charge 3.0; and certainly, even fewer USB-C adapters support Qualcomm’s fast charging standard. What if you already have, say, a USB-C adapter in the office but it supports USB Power Delivery instead?

I happened to have an Apple 87W USB-C power adapter for the new MacBook Pros, which is a USB-PD charger that can do 20.2V/4.3A and 9V/3A, so I decided to do a quick test. With the G6’s battery drained down to around 10%, the Apple charger was measured to be topping up the G6’s charge at around 8.8V at 1.8A.

So yeah (and yay!), like the LG G5, the LG G6 also supports USB Power Delivery.

isn't that too slow? since QC3/USD PD are supposed to allow faster charging pumping more current up to 3A? if the charger charge at 1.8A that like half of the current only?

HELLO, see 1.8A over 9V.... QC 3.0. this is not a horsepower race... number too win.
you send 4A into the phone, you want it to burn ah?

relax la, key is the QC 3.0

Amps are only half the story. What you are actually supposed to look at is watts. To get watts you multiply voltage by amps.

So you need to look at voltage and amps, not just amps. A 'typical' phone charger is 5v and 2.4 amps, giving a total of 12 watts of power.

However in the example above, 1.8 amps is delivered with 9v, so total power is 16.2 watts. Note that the charger can also deliver 1.67amps, but at 12v, so total power is 20 watts.

In summary - don't look at just the amps. You also need to see volts in order to know what the total power output is.

i thought this V x A = Watts thing is basic science taught in sec school? what they teaching kids in school nowadays ah? :s22:

At work, my only power plug is on the floor. If i use a really long USB-C wire (probably 1-2m long), will it drastically affect quick charging speeds?

Not all wires support fast charging. Another option you have is to get an extension cable to get the charger closer to your phone.

I thought of that solution already, but i hope to not do that because it'll make my table messy. Hopefully someone have tried out long quick charging wire!

For me I buy from Amazon, and always use the Benson spreadsheet to cross reference before purchasing. Some of the options in his sheet are available in long form also. See if that helps you.

Lol me same as you. My G4 died 1 day before I went for my Japan trip last week. Had to use my 4 yr old trusty G2 to shoot photos instead. Although I am concerned about the bootloop issue, since G6 offers 2 years warranty, I am willing to give it a go, especially since I don't have any issues with the phone other then the bootloop.

Also considering S7, Sony XZs or P10 plus. Need to try the phones out first then I will decide.

I also had a V10 bootloop. Had a V20 for about 2 weeks but hated it so didn't give it a chance to bootloop on me...
