[G4 General] Lock-N-Load:
So can we all agree - at least in USA - that QC is not actually turned on yet. I kind of thought it would be on, since the acknowledged the chip/phone was capable, but we need to buy our own adaptors. Well, I bought a few QC 2.0 plugs, but I'd say they are doing nothing (I have never had QC 2.0 so not entirely sure what to look for other than "faster" charging - which does not seem to happen). Apparently they acknowledged too late in the shipping cycle to actually update the device to accept QC 2.0. BTW, I have seen companies, even in the ship cycle, send an update to devices so when you got them, they updated when started up.
[G4 General] mugen939:
I've been using my 2.0 charger that I bought from amazon for my Z3 and it is indeed working. phone charges at slightly faster than a percentage point a minute.
[G4 General] LastStandingDroid:
Yup its just not active. And the new M feature doze. is a joke its in the framework of Android 5.0 of both G3 and G4 not sure if active though
[G4 General] Sfkn2:
So.. I'm confused. I got the phone last night and it took like 9 hours to fully charge to 100%.

I don't get my QC 2.0 charger until next week, but ... is it confirmed that it isn't activated?
[G4 General] jeyd02:
No simply that the phone's chip supports it but you need the proper charger for it.
[G4 General] denco1:
It shouldn't take 9 hours even with the out of the box charger, more like 2 hours maximum.

The European H815 will charge at 9V, but the LG G4 draws nothing like the current which other Qualcomm Quick Charge 2.0 devices do.
[G4 General] Sfkn2:
Phew. Okay, I ordered the AUKEY 2.0 QC charger from Amazon.

---------- Post added at 11:10 AM ---------- Previous post was at 11:09 AM ----------

I'm reading from other threads that it's normal to have slow charges the first few times..

Is this not accurate? That was literally my first charge.
[G4 General] denco1:
No phone I have ever owned has charged slowly the first few times.

If you are using the stock cable/charger something is either faulty or they just didn't handshake together properly. I have had that happen a few times, not regularly though.

Like I say using the standard charger it should take around 120mins, you will only save 20mins or so at the moment by using an Aukey charger.
[G4 General] Sfkn2:
Thanks for the information. Is it safe to assume that this is just a guess or an estimate, since you haven't actually used a QC 2.0 charger on the G4? Or is this proven by your device?

The only reason why I question is because there are a lot of G4 users on QC 2.0 chargers who are stating that they are having great experience with their charge times in comparison to the stock charger.

By stating that it's a 100 min with a QC 2.0 vs 120 min with a 1.8V charger, you're not talking about much of a difference.
[G4 General] edlover666:
I know what QC2.0 is. I say it in more then one Post here ;)

But im not sure that jerflash know what QC2.0 really is?!

He sy only working well...but thats no Info for me.

Please more Details or Screenshot. At the End, People read this, buy a HTC Quickcharger and it doesnt work.

[MENTION=3341206]olivercervera[/MENTION]. In which time your G4 charge the Battery in this Constellation we see in Schreenshot with QC2.0 (9V)???
[G4 General] Leo90604:
Is quick charge 0% to 50% within 30 minutes?

From Qualcomm Website:

In laboratory tests using a 3300mAh battery1, a Quick Charge 2.0 enabled device went from 0% to 60% charge in 30 minutes, while a device without Quick Charge 2.0 using a conventional (5 volt, 1 amp) charger achieved just a 12% gain in the same 30 minutes. A device with Quick Charge 1.0 managed a 30% charge in that time period.

So it seems that QC is really a quick top off?

Is quick charge 0% to 100% in 60 minutes?

Is quick charge meant to slow trickle charge after 70%?

I did another test Tmobile H811 and Anker A2130 QC2.0

5% to 50% was about 40 mins

5% to 100% was about 90 mins

I have Ampere pro and did see 2000mA recharg rate and it started dropping to 750 around maybe 70%

It does a slow charge after 75% to 100%
[G4 General] olivercervera:
Sorry but I can't understand you :confused::confused::confused:
[G4 General] edlover666:
[MENTION=2572248]oliver.[/MENTION]...In which time your G4 charge from 5%-100% ???
[G4 General] Kenishi99:
Question: How long does it take to load the battery from 5% to 30%?

Some people here already reported that Quick Charge 2.0 worked on their phone using a usb tester.

But their charge speed was still pretty slow...

How is yours?
[G4 General] StarmanUK:
Believe mine took about 20mins.
[G4 General] Lock-N-Load:
Based on only this of theirs, that means that in that case, they are charging at 2% per minute (60% in 30 minutes). and 2% per minute is what I read is QC 2.0.

So based on 3 tests of mine (mentioned on XDA) with a QC I have gotten, in the best case, half of that at .915%, 1.03% and .97% which means in some cases less than half of their expected results.

More and more, as I have said before, I believe, at least for Verizon USA, QC 2.0 is NOT on. And for the people that have QC chargers with colored lights and think that is "proof" I do not think it is proof, I think the lights switch over not because it is fully QC 2.0 at 2% but because it is slightly better than stock charger and not much more, but it is enough for the circuitry to trip over and show the 2.0 colored light..
[G4 General] danaff37:
That 2 percent a minute is only up to 60 percent, after that it slows for battery protection, so you can't compare charging to 100 percent for testing qc.

Phone on, wifi on, all syncing left on, screen off, I charged from 23 to 46 percent in fifteen minutes (timed by my tablet to check as soon as the countdown went off) That's over 1.5 percent a minute - define qc territory with everything syncing still I think.

My qc charger, a Getwow, came with a usb cable significantly thicker than stock, and gold plated connectors. The fit feels significantly tighter as well when plugging in.

I'm on a vs986.
[G4 General] hunter3160:
This was while I was reading a Manga my screen brightness was at 0% but I have wifi on with sync and GPS and was getting around 1.6mA of the charger also the Manga was not predownloaded so it is downloading as I read the chapters

But while I'm using Tapatalk it drops to 280mA
[G4 General] olivercervera:
Finally I got chance to use the Nexus 6 charger with the G4 running half battery.

The funny thing is

If the screen is off, values are 9.10V. 1.12A

If the screen is on, values go down: 9V, 0.95A (and lower, sometimes 0.70A)

Will tell you later about charging times!
[G4 General] danaff37:
getting values and charging times when at half battery well not be very useful, as qc only works at lower battery percentages. Need to test from nearly dead to half for good comparison of it is working.
[G4 General] denco1:
No, on the LG G4 those values are correct for roughly 0-80%, they are the same values I got about two weeks ago.
[G4 General] misteroh:
TO RECAP

The LG G4 supports QC 2.0... kind of. Using a QC 2.0 charger, the phone charges anywhere from 10%-20% faster than using the normal charger than came with it.

It appears to correctly pull in the higher voltage (9V vs. 5V), but at an amperage much lower than other QC 2.0 phones pull in. I suspect the higher voltage is what causes some of the fancier chargers to change LED colors signaling that it is using QC 2.0 (even though it makes a barely noticeable difference to the phone's charging speed).
[G4 General] danaff37:
See the difference here, first half on quick charger, second half on normal charger. I think it's working.
[G4 General] misteroh:
http://www.droid-life.com/2014/10/16/video-testing-the-motorola-turbo-charger-with-a-moto-x/

This article shows that the Moto X charges at about 2% a minute vs 1% a minute with a normal charger. Is anyone seeing anything even close to 2% a minute?
[G4 General] RedOCtobyr:
I'm really hoping that something is just wrong, and this performance can be fixed with some sort of software update. Currently, I am seeing very-moderate charging performance (admittedly, not using a QC 2.0 charger). I sometimes see my charge level decreasing when running navigation in the car and playing music with a 2.1A adapter. And charging overnight at home using an older 0.7A charger, screen off, my charge level graph sometimes increases, then decreases, then increases, etc. Charging currently can be very slow and inconsistent. I have a US Verizon G4.

I was hoping that QC 2.0 would at least provide a solution for actually *charging* in the car, actually increasing the battery's charge level, even if using navigation, etc. If it's barely better than what I'm seeing now, that is disappointing.
[G4 General] autoprime:
I believe the reason for:

If the screen is off, values are 9.10V. 1.12A

If the screen is on, values go down: 9V, 0.95A

is due to heat. they're being overly cautious to keep heat down on this phone... so even things like QC 2.0 have been tweaked. This my be able to be changed with custom mods (need unlocked bootloader for kernel changes).
[G4 General] olivercervera:
Right, it's just slightly faster. Started from 11%, rates: 9.05v 1.10A.

21:42 11%

21:52 24%

22:02 38%

I thinks is faster than standard charging (1.75A, 5.2V) but not much, as I think I get 10% every 10 minutes with it.
[G4 General] danaff37:
I get a tick over 1.5% with Wi-Fi connection, screen off (but all syncing on, Moto 360 connected). Considering battery size difference, I think that might be okay.
[G4 General] Bootup01:
Might be okay is not okay if all other of qc phones are seeing double or better.

I got ahold of an ankey charger and my results are similar to my first tests, about 1.17% a minute
[G4 General] esqueue:
Sorry if I didn't read the thread but QC definitely works while the samsung s6's quick charger is slower than the stock. I have some rough charges below 50%. Keep in mind that the battery is being charged so that alone will lower the time slightly.

Here is the charge time with my brother's Galaxy S6's charger.

[IMG="LG G4 on Samsung S6 charger."]https://db.tt/iNoDdLVi[/IMG]

Here is the charge time with the phone on it's stock 1.8A charger.

[IMG="LG G4 charging with stock included charger."]https://dl.dropboxusercontent.com/u/84072165/Screenshot_2015-06-10-16-45-23.png[/IMG]

Finally, here is it using a QC2.0 charger that I purchased from Amazon along with a car charger for $24.

[IMG="LG G4 using amazon qc2.0 charger."]https://dl.dropboxusercontent.com/u/84072165/Screenshot_2015-06-10-16-51-16.png[/IMG]
[G4 General] officerdoofy:
Does quick charge work with the phone completely powered off or does it have to be on?
[G4 General] esqueue:
I am 99% sure that the phone doesn't have to be on.
[G4 General] Dozenboy0012:
Yes I purchased a quick charger and from 10% it takes 1 hour and thirty mins to reach 100%. This attachment is the one I bought. Picture taken by my G4 ?
[G4 General] denco1:
esqueue how have you got the stock signal bars? Unlike the normal LG signal bars your stock ones are unbroken.
[G4 General] bayniner:
So can anyone with an anker quick charge charger confirm if it will charge the g4 when its completely dead, mine would not so i contacted anker and they sent me a replacement charger which is the same, it chargers great while the phone is on but it will not charge it if its dead
[G4 General] esqueue:
Unfortunately, that is how my bars are and I hate it. The phone is Sprint BTW.
[G4 General] MicroMod777:
Heads up on some fake Qualcomm 2.0 Car chargers AliExpress is selling. They are NOT charging at 9volts. They are being marketed as so.

Beware, these are them:

****DO NOT BUY****

2015 New Brand ROCK Universal Car Charger with Qualcomm Quick Charge 2.0 Travelling Charger USB Adapter for Apple for Samsung

http://www.aliexpress.com/snapshot/6700918103.html?orderId=67514428734595

****DO NOT BUY****

Real one:
[G4 General] rsbenedict:
Does apple even support quick charge 2.0? I thought it was restricted to qualcomm chips.
[G4 General] bayniner:
My quick charge charger does not charge the phone if it is completely dead, ive tried 2 different ones same result, not sure about when its just turned off but ill try and let you know
[G4 General] Coderedpl:
Weird I'm using the Samsung 'adaptive fast charger' and I get the 'use standard charger to charge faster' and it's definitely not quick charging.

I guess I should maybe try another charger not made by Samsung?
[G4 General] denco1:
The numbers are what Phonearena reported, and they also mirror my findings with a Samsung adaptive fast charger.

http://www.phonearena.com/news/The-...charger...-or-a-Samsung-rapid-charger_id69692

---------- Post added at 07:26 PM ---------- Previous post was at 07:24 PM ----------

Are you using a USB cable with data support?

Try using the stock LG cable if you are not already doing so, there should be no compatibility issues between the Samsung adaptive fast charger and the LG G4.
[G4 General] Sfkn2:
Holy snaps. This definitely is in agreement with the people who are complaining about slow charging - everyone who has mentioned slow charging has been using either stock or Moto/Nexus 6 charger!!

I've never seen the Samsung charger being used though, but I don't have a Samsung charger laying around either hmmmm.

Thank you very much for this info!
[G4 General] Coderedpl:
Pretty sure it has data support. My note 4 fast charges with this charger without issue.
[G4 General] Lock-N-Load:
Contradictions here guys.

We know the phone supports it

, but I do not think it is actually turned on yet, but I am not sure if there is a way to confirm this. Nothing is said in the battery settings, no notation is made, no way to really know for sure it is fast charging if using a QC capable charger.

I bought a 2.0 charger, but I don't feel like anything is any faster for charging.
[G4 General] ectodroid:
Qc works fine with the nexus 6 charger. Charges as fast as my n6, both phones have around the same mAh.
[G4 General] Lock-N-Load:
So how do you "know" this? By "feel"

or

is something showing you you have a QC connected and working

or

did you do an actual test with a QC and non QC charger and compare?
[G4 General] BDestroyer8418:
I bought a Aukey 2.0 QC. I only charged the phone 2x so far but when the Ampere app open and screen on the phone was charging around the 320-360 mA and then when then screen turned off and the app still running then turned on screen it was charging at 1970 mA for me. But as soon as it tells me 1970 mA it drops down fast to the 320-360 mA range. I don't remember the start time but did seem to charge 45% in about 45 mins or so give or take 5 mins. So does this mean it's not charging fast while in use ?
[G4 General] olivercervera:
Don't use Ampere app as it's not 100% accurate. I'm waiting for my voltage/ampere USB tester to be delivered, and I will do some testings as I have some fast chargers.

At the moment I have tested the G4 charge with an Anker 40W multi charger, that provides at maximum 5V 2.4A, but the G4 will eat 1.8A realistically. Anyway, I get 1% every minute of charge:

- In 60 minutes I get 60% of battery

- Battery fully charged in 1h 45m

Since I get 60% in 60 mins, the phones does charges at 1.8A

Obviously I'm using a very good USB cable (I did not even unpack the LG cable or charger lol)
[G4 General] BDestroyer8418:
Ok thanks didn't know. Just seen some people using that app. I also have the Anker charger on the way the 18w 2.0 QC. Yea I haven't unpacked the LG cable or Charger yet as well since I had a few chargers ready to go already.
[G4 General] mugen939:
I'm using a tenergy QC charger. It has a confirmation light on the charger itself when it's plugged into a 2.0 capable android device. If I plug it into anything that does not support quick charge the charger stays blue once it senses QC it turns green. It's green on the G$ and I'm getting one percent a minute as well. The same I would get on my Z3.
[G4 General] Lock-N-Load:
IS this a USA phone, UK phone, phone from Asia, etc.? thanks.
[G4 General] mugen939:
It's a US T-mobile variant.
[G4 General] psechler:
back on the wireless charging issue...

Is the only case that has wireless charging the "black velvet" official LG quick circle case? Why purple, c'mon. I've searched everywhere and it's the only QI case. And where I've seen it sold, you gotta be careful because they typically sell the non QI wireless charging quick circle case also.
[G4 General] smw6180:
I bought the JDB travel charger and I can confirm 1% a minute when it's plugged in.
[G4 General] Coderedpl:
To those of you who have quick charge working correctly. Is it working with the phone off while in use or only screen off?
[G4 General] Nayr12:
for some reason the one released here in the philippines is a dual sim and the back cover is wireles charger ready as i can see contacts on the backcover
[G4 General] snir6590:
cool.. but do we have to buy a TURBO CHARGER?
[G4 General] Sfkn2:
You don't have to buy the turbo charger for Nexus 6 / Moto if that's what you mean. A QC 2.0 would work just fine.
[G4 General] :
Any 2.0 turbo charger should work unless LG implemented a check like Apple

You must have much stuff running MY G3 with original cable

What you can do to speed up the progress is disable all unnecessary apps. Close and disable data and WiFi. This will help the charging time greatly.

Indeed you're both correct and wrong. Depends on how much battery the phone drains in current state. Will interfere with the charging time.

I never charge my phone first thing I do. but I don't think it should take that long. I think it said mine was going to take 4h

Might be a temp issue only. Depends on what cable is being used. some cables doesn't even want to use media transfer while on a computer. Simple as that

Well if it is charging faster it is due to more v is going through the cable. but it has nothing to do with the fastcharge on the phone as of now. (Since what I read) it isn't actually active. But I can't tell for sure. but it seems that it should be selectable.
[G4 General] denco1:
Look I'm going to post some more info, I don't understand what people aren't getting.

Using any charger with detects the phones request for 9V, the phone will charge at 9V. This means any Qualcomm quick charge 2.0, adaptive fast charger, turbo charger etc.

When the phones screen is off it will draw around 1.2A at 9V between around 0-80%.

When the screen is on it will never draw more than 0.96A at 9V.

This results in a charge time of around 99mins if you are not using the phone at the same time, which makes it probably the slowest quick charge device out on the market at the moment.

I do not know whether LG plan to increase the current that the G4 accepts by changing the kernel, as the power management chip LG have used will accept around 1.6A which phones like the Moto X 2014 and Galaxy S6 accept.

The phone will also charge at 5V 1.8A, however it is very fussy with this and you must be using a high quality USB cable something like 20AWG. The stock cable is actually better than most third party cables. Again while the screen is on it will not draw the maximum current of 1.8A at 5V.
[G4 General] Lock-N-Load:
What we are not getting is there is no actual definitive proof. Just anecdotal comments and theories and suppositions and explanations in circles. No proof QC 2.0 is active and working and turned on on the chip.

Everyone understands the phone has a chip that is QC 2.0 capable.

Everyone understand what QC 2.0 does.

Everyone understands that you need a QC 2.0 charger to make QC work.

Everyone understands that it "should" draw certain amps over non QC charging.

Everyone understands what the charging time "should be" with a QC versus non QC charger.

Show me an app or a tool or something I/we can use to plug in a non QC and a QC and see the numbers to prove it is active. Yes, I have read some vague info about charging tests at "99 minutes", but still nothing definitive and confirmed or retested.
[G4 General] denco1:
You still haven't understood, phones which use quick charge can draw different currents and therefore take different amounts of time to charge. Quick charge 2.0 just means the phone can accept 9V, not that the phone has to draw 1.6A.

Here's another link which contains images of the phone charging at 9V and 0.96A.

http://m.mydrivers.com/newsview/431081.html?ref=https://www.google.co.uk/

I'm not bothering to upload photos of my LG G4 charging at 9V 1.17A because I know it is and I should not have to be proving myself.
[G4 General] Sfkn2:
I think we just need some Ampere logs.
[G4 General] Lock-N-Load:
Yep.. some amp logs, or a reliable proven app that shows the difference when 2 chargers applied or a statement from a dev that can check and see that it is active or a statement from LG that it DID ship the phones with QC 2.0 enabled.

One singular dude on the web saying, "yeah, it's on and I know it so that is all that matters" does not work for me as just as many others are saying, "yeah, it does not appear to charge any faster with a QC attached".
[G4 General] MicroMod777:
I use the Tenergy 18W USB Universal AC Wall Adaptive Fast Charger Qualcomm® Quick ChargeTM 2.0 that tells you when your using 2.0 charge. The light turns green when on 2.0, and blue when not. When I plug in my LG G2, light turns blue as it does not have 2.0. When I plug in the G4, it turns Green.

Now tell me if the G4 wasn't charging on Qualcomm 2.0 technology, then why is this charger turning Green when plugged in? To me this is PROOF!!!!!

Here's my charger!

http://www.amazon.com/gp/product/B00OVD3FEU?psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00
[G4 General] denco1:
Right, I may just be one singular dude but I have also linked a website which has nothing to do with me.

The reason it doesn't appear to charge any faster using a quick charge 2.0 charger is because it isn't significantly.

Unless you have two LG G4s and have one charging at 5V and one at 9V or you do a scientific test from 0-100% you are unlikely to see much difference.

Like I say, I don't know if LG will speed up the phones quick charge capabilities by allowing the phone to draw a higher current than it is currently doing so at 9V.

I have posted my own data along with two other websites, I'm not going to post much more as why I should need to prove I am not a liar when I'm just trying to post useful information I have no clue.
[G4 General] Sfkn2:
Hey man, no one's calling you a liar and no one is asking for you to prove anything. We're all just here to learn and we definitely appreciate the research that you have done and that you are sharing with us. I, along with a few others, simply don't/can't understand and would just like a little more help, that's all. I hope you don't take this the wrong way.

<3
[G4 General] denco1:
OK sorry I overreacted a bit aha.

But the LG G4 is definitely charging at 9V and this includes all variants, this is why certain power adapters are lighting up the relevant LED to show this.

The reason some do not think Quick charge is activated because LG have not allowed the G4 to charge anywhere near as fast as some other phone like the S6/Moto X 2014. It will still charge quickly compared to some 2013 but not really compared to 2014 phones.
[G4 General] tourbound129:
I will hopefully be picking up 2 G4's on Sprint tomorrow and I have the Tenergy charger linked above. I can do a side by side comparison of the Tenergy vs standard to compare charging times if that would help?
[G4 General] MicroMod777:
Heres the G4 on 2.0 charge with led green.

Now here's my G2 with no 2.0 capabilities on blue led.
