Stock charger isn't quick charge 3.0?? - LG G5 Questions & Answers

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

---

i just installed some dual 2.4A usb outlets in my house they charge very fast from 8% to 100% in about an hour, considering the Amperage on the stock charger is 1.8A it doesn't seem like it would be enough to use the phone while charging.

---

I havent used the stock charger yet but mine reads it puts out [email protected] 1.8amps or [email protected] 1.8amps. I am waiting for my battery to get really low so i can see how fast it will charge.

When the OEM charger is plugged in, swipe down and you can see it says it's being fast charged.

---

When plugged in, my screen does say Quick Charge, and my phone charged rather fast, but still getting used to it. Even when I had my phone plugged into a normal new USB C plugged directly into my usb outlet, it seemed to charge much faster than I was expecting.

---

Yes I understand it says fast charging, so does the quick charge 2.0 with this phone, but is it actually charging at QC 3.0 speeds??

---

It seems silly they would make a Quick Charge 3.0 phone and not supply the relevant charger.
I ordered an aftermarket QC 3.0 charger, I guess I can do some comparisons when it shows up.

Anker makes a very nice Quick Charge 3.0 charger.

I got this one, it's half the price. Will be here today.

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.

Well if the stock charger says 9V @ 1.8A and 5V @ 1.8A, then it's not true QC 3.0 as that uses voltages from 5V - 20V.

There only will be a minimal effect because the original charger has a 9V and 1.8A = 16W rating.
All Aftermarket charger with QC 3.0 had a maximum reading of 18W, 9V at 2A or 12v at 1.5A.
And you can't do a comparison at the last 10%percent of the charging process, because of of the method that's just to charge lithium battery's.
Lithium-ion battery see charge and discharge
Around the last 10% will be constant voltage where the charger has minimal influence. Because the internal resistance of the battery cause the amount of power that goes in the battery.
Ca you do another test with larger charge?

Before any of you rush out and buy a cheap charger to save a few bucks I'd think twice about it. I have been screwed by cheap chargers on more than one occasion which is why I refuse to buy them anymore.
I've had them stop working after a couple weeks and many of them made a very annoying noise. Some made a high pitch squealing noise while just sitting there doing nothing and others made the noise while charging.

Slow and Fast
I noticed it charged VERY slow at first while i was using the phone at the same time. I notoced the charger wasnt even slighty warm to the touch after 30+ minutes. That made me think and noticed if I left the phone at rest without turning it on it charges much quicker and the charger got warm quick. And the charger actually cools down if you start using it half way through a charge.
*I took a screen shot of the battery usage graph, but I'm new so I can't post photos yet so you'll have to trust me lol
My rough estimates are that if you are using the phone while charging it will take just over 2 hours, but if you don't touch it then it charges in under 50 minutes.
Mind you phones battery temperature also effects the charge rate, is if you have it on top of a pillow it might not charge as quick.

You don't wanna use the phone while it quick charges. Turn screen off for an hour and it will be done

Dude how are you basing charging speeds from 90% to 100%.../

The charger that came with the G5 is the same charger that came with my v10, it is only Quick Charge 2.0, I have compared the model #'s and they are exactly the same. I have gone on amazon and ordered a Anker Quick Charge 3.0 plug and a couple of their USB-C cables.

I just contacted LG through their website via E-Mail regarding the Quick Charge 3.0 charger, I will follow-up once I receive an email back from them. The website advised that I should receive an email within 24 hours.

I have drained to 50% and am performing the same test with the factory charger now. Will update results later this evening so I can repeat with the aftermarket charger.

It's a wonder why anyone tries to share information on this site with comments like this. Since you probably only skimmed over what I posted, I said feel free to draw your own conclusions and that it was a 'quick test'.

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
