Stock charger isn't quick charge 3.0??

When the phone gets to 80 % the other 20% go pretty slow, might even be similar to the QC 2.0... But 50% to 100% would be a good test, and we can see if there's a difference
You are correct. After 80% it trickles in even with 3.0. So all these tests are pointless. Install ampere from the play store. All is well

I've done tests from my g4 and g5, whilst my g,4 maxed out to 2100mah during charge from 20% to 80% the g5 pushed my charger to 3200mah in the same ranges. The charger was an anker QC 3.0 as this charger scales with the phone and it's max amps it can take. The time for both is moot to the 80% from 35 min for the g4 to 28 min for the g5 due to increased thresholds. Charging faster albeit miniature. This was tested with the app ampere :)

Anker makes a very nice Quick Charge 3.0 charger.

I was curios about the long projected charge time with the stock charger and switched over to a QC 2.0 by Aukey that I had purchased earlier. It charges much more quickly than the one that came in the box.

I like to point out that the LG charger is not QC 2.0, it only supports QC, if you look at the spec of the LG charger and a true QC 2.0 charger, you will notice the LG charger does not support 12V charging.

Charger that comes with this phone is just labeled fast charge... Phone seems to charge pretty slow also from what I see.

Slow???? Are you serious? My phone I could swear goes to full in like an hour. Compared to my Sony z3 and Sammy s4 this charger kicks but.

But what it means fast charge ? how many Mah ? it's like Quick CHarge 1.0 ?
We have to buy a new charger to benefit Quick Charge 3.0 ?
LG calls its charger fast charger because if it uses the name Quick Charge It will have to pay royalties to Qualcomm since it is their technology. It does not make sense for LG to Fork up more money just to label its charger with the same name that Qualcomm has made a name for itself on.

You can ask the manufacture that, samsung, HTC and LG label the charger fast charge, none of them come supplied with QC 3.0, although HTC and sony does have the charger QC 2.0 as a optional accessories.

I agree, although the LG one isn't even QC 2.0, it does charge very fast.

Charges at same speed as QC3 it's just at a fixed voltage of 9v unlike the QC3 that varies according to my cheapo amp meter. I guess the only benefit of QC3 is the varying voltage could help counter longer cables & more efficient so less heat.

in the UK the charger actually says QC 3.0
Mine from EE just says fast charge. Where did you get yours?

EE as well, they were selling the phone for £399 - BARGAIN for a flagship!!!!

mind you the samsung adaptive fast charger which u can get online for £5 charges as fast IMO:

So from what I understand, QuickCharge 2.0 and QuickCharge 3.0 have basically the same maximum Wattage threshold of 18W. The biggest difference lies in the "efficiency" where on Qualcomm's website it says "Specifically, Quick Charge 3.0 offers a more granular range of voltages: 200mV increments." And I'm pretty sure that has less to do with the charger than the phone you're charging. Meaning, if the phone has the correct setup and is rated for QC 3.0 then as long as you supply a charger with enough Wattage(18W) you are "getting" QC 3.0. Basically, going out and buying a charger that has 18W of output power vs the stock charger that has has 16.2W for your G5 is probably just a waste of time.

Just starting to notice QC 3.0 coming into its own. Whilst using the phone, the non QC 3 charger is charging at about. 300mA but the QC 3.0 is at 1000mA & feels a tad cooler too.

Guess that's the advantage of granular voltages kicking in ?

Needs more testing but it seems a consistent advantage

Definitely better charging rate with QC3 when screen on. 1st 2 images are LG non QC 3.0, 3rd & 4th are QC 3.0

The former seems to pick up a little when temp goes below 35c but still not a patch on the latter.

(yellow marker indicates when screen on)

I performed a test with the aftermarket QC 3.0 charger linked above and the one supplied with the phone. I drained to 90% and as soon as it hit 90 I plugged it in and started the timer. The results are nearly identical in how fast 100% charge was achieved.

The first screenshot of total time was the aftermarket charger and the 2nd is the factory charger. I would venture to guess based on these results, the factory charger is QC 3.0, but you can draw your own conclusions.

Your test is very flawed. A test from 90% back up to 100% shouldn't reveal much if any differences between a Quick Charge 2.0 and a QC 3.0 The reason is that the whole point of the Quick Charge technology developed by Qualcomm is to have a very rapid charge from a battery that is at or near 0% and get it to 50% in a very short time. Then as the battery reaches its full capacity it slows down to a normal rate so as to not damage the battery. If you let your batteries drain to less than 15-20% and then try your test you'll get a much different complete charging time.

Some G5 fast charging compatibility data

I have noticed that G5 is rather picky about fast charging adapter. Below are my observations:
Good results:
G5 with G5 adapter (rated 9V 1.8A) - fast charging (2000 mA)
G5 with Nexus6 adapter (rated 12V 1.2A) - fast charging (2000 mA)
G5 with HTC QC 2.0 certified adapter (rated 12V 1.5A) - fast charging (2000 mA)
Bad results:
G5 with Samsung fast charging travel adapter (rated 5V 2A) - slow charging (500 mA)
G5 with Asus fast charging adapter (rated 9V 2A) - slow charging (500 mA)
G5 with Nexus5X fast charging adapter (rated 5V 3A) - slow charging (500 mA)
G5 with Nexus6P fast charging adapter (rated 5V 3A) - slow charging (500 mA)

Also I have noticed that cables do not make any difference to charging: I have 5 different USB TypeA->TypeC cables and 4 different microUSB->TypeC adaptors - they show no difference to charging current at all.
