Is it just because the S6 and Moto X both have much smaller batteries or what?

I mean yeah, it's really hard to tell unless we have two same phones sitting side by side on different chargers. I haven't received my Aukey QC 2.0 charger but I'm kinda iffy on whether I've just wasted $15.

The thought of getting ripped off scares me, especially since I've had issues with LG in the past (like the G2 and G3 having ****ty screens/digitizers that breaks knock-on), but I do understand that the QC 2.0 is really only good from 0-50% or whatever, because it's supposed to slow down after that in order to preserve battery.

I guess what really matters is that in case of emergencies when the battery is completely out and you're in trouble, you can either grab the QC 2.0 charger and pray it charges fast while the phone is off... or...... swap in the battery that LG is sending all of us :)
[G4 General] misteroh:
I'm using this quick charger: http://www.amazon.com/gp/product/B00QEX83LA?psc=1&redirect=true&ref_=oh_aui_detailpage_o07_s00

It doesn't seem faster than my normal 5V 2.4A charger... I'd have to sit down and actually do a real test to know for sure though. :-/
[G4 General] Sfkn2:
That's the exact one I ordered...................................
[G4 General] denco1:
Partly to do with battery capacity but i would say mainly to do with how the device charges.Motorola have implemented it so it charges at 1.6A(14.4W) 0-50% and then slows down. I don't know how Samsung have implemented it but I assume similarly as it also charges very fast.

LG are letting the phone draw 1.2A (10.8W) 0-80% and then reducing current, similar to what most phones do at 5V.

I wouldn't say you have wasted your money as the charger will be compatible with many phones released in the future, however until LG or someone else modifies the kernel to change the charging behaviour the G4 won't charge significantly faster using a fast charger compared to any other >1.8A 5V charger.
[G4 General] misteroh:
Could you elaborate on where you got those 9V@1.2A (10.8W) numbers from? If so, that's really silly of LG because that's only 20% higher than 5V @ 1.8A (9V)
[G4 General] denco1:
From my USB current/voltage tester. That is why reports show only about a 20min decrease in charging times because only around 20% more power is being consumed.

Yes it is really silly unfortunately, but until LG or someone else change the kernel that is what we are stuck with.

I can only assume this is the reason LG chose originally not to market the phone with having quick charge 2.0 capabilities.
[G4 General] misteroh:
I see! Sorry I also just saw the link to the Chinese page you posted earlier in the thread.

OK then that answers why the quick charger doesn't seem to charge our G4's that much faster.

Unfortunate, but on the plus side I guess that means it'll be very easy for someone (if not LG) to update the kernel to boost the amperage the phone will eat up to charge the battery,

I wonder why LG elected to do this... Extend the lifespan of the included battery? Reduce the chance of some sort of fire? hahahah
[G4 General] hella356:
This would probably shed a lot of light on the question. Thanks, looking forward to your findings!
[G4 General] didi_ghost:
I bought that one too, and today i've tested it and it looked almost the same as charging with the default charger... I think i'm going to return this charger.
[G4 General] misteroh:
Don't bother. It's a software feature of the phone that's limiting how quickly it will charge even with the higher 9V. You'll get the same with any other quick charger
[G4 General] didi_ghost:
I mean, i'm going to return it and don't buy another one since it's useless to have a QC2.0 if the G4 doesn't really charge faster...
[G4 General] tourbound129:
As long as best buy didn't screw up my pre-orders it should be pretty easy to get done.
[G4 General] misteroh:
Oh I see. I thought you meant you were going to return it and get a new one.

I'm in the same boat. I think I'll keep it though. It'd be such a quick and easy fix for any developer to make the quick charging faster if LG doesn't do it officially.
[G4 General] didi_ghost:
That's good for people that are searching for custom roms and stuff. And for those that aren't? This could be considered fake advertisement from LG since i bought this charger to make it charge quicker and simply doesn't charge. And if it does, the differences are minimal.
[G4 General] Sfkn2:
That brings up a good question - did LG actually announce that it comes with QC 2.0, or did someone just assume that because it runs on a 8xx series QC chip? As I recall though, my G2 with the 801 didn't have QC 2.0, and neither did the 805 G3, right?
[G4 General] denco1:
You are right, the G2 and G3 didn't have QC2.0, they came with different companies power management chips however, the G4 is definitely using Qualcomms this time.

LG originally stated the G4 didn't have QC2.0, then Qualcomm said it did and LG then stated it did, but that it wasn't a big deal. I can imagine the reason they didn't originally advertise it or make a song and dance about it is because they have no plans to up the current which can be drawn above 1.2A.
[G4 General] didi_ghost:
No, they didn't announce that G4 had QC2.0 on the presentation day, only a few days after they (or someone?) said that after all it supports. I really don't know what to think about this. I really think that i 'm going to return this charger, it's useless to have it since i'm not going to swap phone untill the next year and from what i've tested the G4 doesn't charge faster with QC2.0.

And btw, LG G3 has Snap 801, not 805.
[G4 General] denco1:
But LG haven't made any claims saying it charges x amount faster using a QC 2.0 adapter so I'm not sure it is really false advertising.
[G4 General] jbdan:
I haven't read the entire thread but I've been using my nexus 6 charger (the moto turbo one), and it charges my g4 from almost dead to full as fast as it does my nexus 6
[G4 General] inick73376:
So can I use the Nexus 6 charger that came with the phone, To charge my LG G4?
[G4 General] didi_ghost:
Hmm, that's strange. How does that charger work and the other ones don't?
[G4 General] inick73376:
Exactly how it is for me too. :) So I can't tell a difference.
[G4 General] misteroh:
I'm still going to be skeptical until we see some hard numbers. It hardly seems like a very rigorous test
[G4 General] didi_ghost:
Moto turbo charger works for you too?
[G4 General] Lock-N-Load:
first, thanks as that is a reasonable bit info and an actual tangible data point as it is something digital with an ability to discern current giving you data and visual feedback like an app - versus a person just saying, "oh yeah, it works".

Second, you are only now just chiming in so, so any comments I made until this time are not aimed at you so eeeeasy tiger.
[G4 General] inick73376:
Yes. Its seems to work just fine. The battery charges pretty quick just like my N6 did.
[G4 General] didi_ghost:
Just to make sure. We are talking about this charger right? http://www.amazon.de/Motorola-Turbo...=2025&creative=165953&creativeASIN=B00PGQXJ0G
[G4 General] inick73376:
Yes, That looks like the one my N6 came with. :)
[G4 General] didi_ghost:
Okay, i already started the return process of the charger i got. I am going to test that Motorola Turbo Charger on a local store and report something out too.
[G4 General] inick73376:
Well I hope you like the charger if you decide to get it. :)
[G4 General] didi_ghost:
Well, it's not case of like it or not. It could be the ugliest charger the world, i just want him to work lol.
[G4 General] inick73376:
Well I meant as in having it work the way you want to.
[G4 General] didi_ghost:
I hope so :) . And again, for the people that bought the Aukey Quick Charger 2.0 just like me, i just have to say: It doesn't work. If it does, no differences are noticable. The phone still took me the same time to charge.
[G4 General] larsdennert:
If you are charging the G4 (3Amp battery) at 1%/minute then it takes 1.5hr to charge it. Effectively you are charging at about 2ah (5V 2A or 9V 1A). This is double the speed of the average 1ah phone and charger. However, it is NOT running at QC2.0. This is basically QC1.0. Better than the average phone but not crazy fast like the Droid Turbo with the Moto QC charger which is twice as fast again (9V 2A).

I mentioned before that Aukey charger is weird . I returned mine today. I have the Tenergy and its showing Green LED with 1% per minute screen off.

I don't know, I didn't know the other ones didn't work. I don't know what exactly "other ones" you are referring to. I haven't done any hard data tests or anything just making regular observations. I'll try timing it if I get a chance :thumbup:
[G4 General] kanzone:
Take a look for QC2.0 on my G4 Dual by Samsung EP-TA20UWE charger:D

from 7% at around 09:25AM to 100% at 11:04AM
[G4 General] larsdennert:
A perfect example of QC 1.0. I wouldn't be surprised if LG figures out how to flip the switch for QC 2.0 since the hardware is in there. When they do, you'll see a charge to 60% in about 15 minutes.
[G4 General] Bootup:
Yea, that's not QC2.0.
[G4 General] didi_ghost:
That's the S6 charger right?

It's not 2.0 ? So how does it charge fast?
[G4 General] edlover666:
No the real QC2.0 is faster!

Phonearena have same identical results....so ist not QC2.0 :/

oO LG....WHYYYYY??????

http://www.phonearena.com/news/The-...charger...-or-a-Samsung-rapid-charger_id69692
[G4 General] kanzone:
Yes, this is S6 charger.

I'm trying to drain the battery and confirm the charging voltage on engineer mode.
[G4 General] edlover666:
Ok thats good. Drain with Benchmarks or a game ;)
[G4 General] denco1:
If I'm not mistaken the G4 dual doesn't support QC 2.0, I think this was confirmed by LG.

---------- Post added at 10:01 AM ---------- Previous post was at 09:57 AM ----------

And people the G4 does support QC2.0. All supporting QC2.0 means is that the phone can support 9V or 12V. QC1.0 was more about supporting 2A at 5V.

No Motorola is drawing 9V at 2A, the official turbo charger is only rated for 9V 1.6A.

And you most definitely will not see a charge of 60% in 15mins ever with this phone, the best you are likely to achieve is 30% in 15mins.
[G4 General] geoff5093:
Sounds like while the phone supports it, the kernel doesn't, otherwise LG would have advertised it. Hopefully an OTA can enable it.
[G4 General] kanzone:
Well, It's only 4010 mV when using S6 charger on G4 Dual.

I found that "High Voltage TA Status - Not support", maybe High Voltage TA Status = QC2.0?

Can anyone confirm on G4 using 277634#*# > SVC Menu > Battery Test > Charging Test?

Thanks.
[G4 General] edlover666:
Here Members say the Aukey carge the Battery from 30%-70% in 40min????!!!
[G4 General] denco1:
4010mV is just the voltage that the internal battery is at.

I'm also getting high voyage TA Status not support, but my phone is definitely accepting 9V.
[G4 General] kanzone:
I see, maybe I will buy a new USB meter for test, because my current USB meter only support up to 7V.
[G4 General] frappe33:
Was the G2 camera really that ****ty? I remember thinking it was pretty good...
[G4 General] kanzone:
I made a USB meter and the result is 9V when charging.:):)
[G4 General] kanzone:
When start charging for 5V for few seconds then it increase to 9V.
[G4 General] Lock-N-Load:
I guess I opened a can of worms by bringing this back up a few days ago - now that we all are getting them in hand - and we still cannot all agree as to if QC 2.0 is actually turned on. Every other posts says yes, no, yes, no and one guys posts makes you think it's on, the next guys post you see the reason why it must not yet be turned on :)
[G4 General] larsdennert:
I think the proof is in how long it takes to fully charge the battery.

The battery is a 12Wh rating (4v * 3A) using the Motorola quick charger 15Wh should yield about a 45min charge. I misspoke about 4%/min but 2%/min would be about right.
[G4 General] olivercervera:
My voltage/ampere USB tester finally arrived!

Using a Samsung cable and the classic 2A charger, I get 1.73A @ 5.19V, it is a stable value and I imagine is the maximum that the G4 can actually reach with a standard charger.

No luck with the Samsung Note 4 "Adaptive Fast Charging", it does not go over that value.
[G4 General] Sfkn2:
Please please please please test that with a stock charger pleaseeeeeeeeeeeeeeeeee
[G4 General] denco1:
That is very surprising olivercervera. Could you check whether your USB tester has data throughput, that is neccesary for QC2.0 to work.

If it has two USB outputs try using the second one.

Also could you take a photo of the power specifications on your Samsung adaptive fast charger, the one you have taken a photo of isn't capable of supplying 9V.
[G4 General] olivercervera:
The one in the picture is the "classic" 2A/5V charger (I think from an S4).

Tonight when I will get home I will try with my Anker 40W wall charger to see if there are differences. I have other good cables too but I probably won't exceed 1.75 or so.

I don't have the Adaptive Fast Charging at the moment here (is from a friend), I'll try to catch it on Monday. I have another friend with a Galaxy S6, I'll ask for his charger too.
[G4 General] denco1:
Yes you will only see around 1.8A from a 5V charger, nothing more.

I would expect you to be able to get 9V 1.2A from a Samsung adaptive fast charger though, that is what I and some others are getting. Hopefully you will be able to get that on Monday.
[G4 General] olivercervera:
Do you actually get a notification when using a fast charger? Galaxy devices show "Fast charger connected"
[G4 General] denco1:
No LG haven't enabled a fast charging notification, only a slow charging one.
[G4 General] MicroMod777:
I cropped the photo and it was in low light thats why it looked like that. Plus the G4 takes great low light pics.

I just ordered this Stouch USB Power Meter USB Charging and Data Sync Cable coming Monday.

USB charging voltage and current display,Data communication function

Simultaneously displaying of Amp and Volt in real-time

Measuring Range: Voltage 3.0 ~ 10V Current 0 ~ 3A Accuracy: +/- 1%

This test can be a USB charging current, voltage, discharge capacity, intelligent devices.

It can be very easy to find digital device charging problem.

I'll test it with Tenergy charger and Aukey Quick Charge 2.0 10000mAh Portable External Battery Fast Charger (16.2W / 5V 9V 12V Supported, Quick Output)

Since this cable tester support up to 10V so I'll see it'll get 9V.
[G4 General] tourbound129:
Today was the first day i actually paid attention to how long it was on the charger and i made myself not touch the phone. I have the Tenergy charger and the phone charged from 9% to 88% in 70 minutes.

Should it be doing better than that?
[G4 General] MicroMod777:
Probably so, should be around maybe 1% a minute from what I've read on 2.0 charging. But remember, we have a 3000mah battery, so its got lots of capacity to fill. Not sure what battery capacity those other phones were that I read up on.
[G4 General] tourbound129:
I'll try to run it down to the same point and charge with stock charger and see how that goes.
[G4 General] edlover666:
The Original take a little bit longer because he has 1,8A at 5V. The Tenergy has 2A?! But when the Tenergy give 9V at the G4 the Battery was charged faster, in around 1h with QC 2.0.
[G4 General] Lock-N-Load:
So at 7:17 I put my phone on the QC with 46%. At 8:16 it was at 100%. So that is 54% charge in 59 minutes. Screen always off.

Is that quick charging?
[G4 General] edlover666:
Noooooo :P it is quick but no Quickcharge 2.0^^
[G4 General] Kenishi99:
I compared the AuKey Quick Charger and a 'standard' Sony charger.

For the results take a look on the screenshot.

There's not be a big difference...

What do you get with your quick chargers?

So how fast should Quick Charge 2.0 be?

What is the average % per hour when charging?
[G4 General] bayniner:
I purchased the anker quick charge charger, used it last night for the 1st time, i plugged in my phone with 15% at 12:45 and my 2:20 i was getting battery is charged notification, so it took an hour 35 min to charge 85% that seems pretty quick to me.

Stock lg charger seemed like it would take like 3 or 4 hours to fully charge
[G4 General] edlover666:
No no no guys...Sorry but is normally. Its faster because they have more Amps as the Standard Charger. Original 5V 1,8A. When use a other Charger with 5V 2A it is faster BUT no Quickcharge! Quickcharge use 12V or/and 9V with around 1,2A. 12x1,2=14,4Wh. Original 5Vx1,8A=9Wh.

You see Quickcharge have a lot more of Power (over 50% more). My Aukey have 18Wh. This are double of Power. So you must have 2%/Minute.

Much more as 85% in 95min!!! See here or please use Google ;)

Tomorrow i become Motorola Turbocharger (Nexus6) and Test it! The Aukey doesnt work!

The Tenergy (works on Post #102???) i can't buy in Germany.
[G4 General] Kenishi99:
Good to hear that it isn't Quick Charge 2.0. Was a little bit disappointed before.

Please let me know if the Motorola Turbocharger works for you. :)
[G4 General] Lock-N-Load:
Just as I suspected. This is on Verizon USA.

I am not sure what the average is BUT I know that I bought QC 2.0 JDB chargers rated by Qualcomm and that have 18w - so unless both QC chargers are faulty, this means QC 2.0 is NOT turned on in these USA Verizon versions. Agreed?
[G4 General] srod562:
My LG G4 went from 25% to 88% in 1 hour using this Aukey quick charger that says it supports our phone. Does that sound like it's working and quick charging?

[G4 General] srod562:
Now that I research it more it looks like it isn't truly quick charge 2.0 which is a bummer. These charger companies shouldn't be advertising it as a compatible device if it doesn't truly work to its full potential.
[G4 General] tourbound129:
I'm definitely not impressed. Used the Tenergy charger yesterday and it did 79% in 70 minutes. The charger in the box just did 75% in 70 minutes so not a big difference. I'll be trying the Samsung rapid charger tomorrow but don't have high hopes. Might just save some money and send both QC chargers back.

So my anker quick charge charger wont charge my phone g4 if it is completely dead is that normal? I have to plug it into the original charger for it to turn on wait till i get like 2% then i can switch to the quick charger and it will charge

Now thats scary. What if thats all u had on a trip? I'd personally return it back to Amazon as defective.
[G4 General] crazyGD:
I have 2 anker 5port 40w powerIQ wall Charger. It cn charge from empty to full. Maybe the anker qc2.0 u got was just defective. Try return to Amazon & have them replace it. So far my experience with anker is great. Also found a review bout anker micro usb cable to be of good quality as it doesn't drop voltage and wattage that much compared to other more expensive brands.

---------- Post added at 01:56 PM ---------- Previous post was at 01:42 PM ----------

Based on the post I've read so far the best way to know if the charger is working as QC2.0 is to have a usb power meter that can accept a max of 12-13v 3amp and can show the actual wattage being transferred for charging. Based on the reviews I read QC2.0 charges around 1.5-2hrs for a 3000mah battery QC 2.0 support smartphone. If you used the phone while charging, it will drop the fast charge method and goes back to 5v instead of 9v.
[G4 General] doki81:
i am using the anker 5 ports 40W IQ charger and the charge reading i am getting from my Doctor Charger device is around 1.69-1.89A is this the fastest charge it can draw?

[G4 General] Leo90604:
My Test

I used my old LG G2 charger (looks like the LG G4 charger) and Anker Qualcomm QC 2.0 model A2130 charger (probably a Tenergy charger and rebranded as Anker).

Using LG G2 charger it took 5% to 100% 2 hours (120 mins)

Using Anker Qualcomm 2.0 charger it took 10% to 100% 1:40 minutes (100 mins).

I believe QC 2.0 goes from 0-50% in 30 minutes and it starts to slow down after 90%.

I made sure I drained battery to 10% before using Anker Quick charge.

So I'm not sure if QC is enabled on my phone. Using Tmobile USA version.

Also I noticed the Tenergy one has 2 lights (Blue for normal charge and Green for fast charging).

I plugged in Nexus 7 and LG G2 . Light stayed green. Even without anything plugged in the light is green. Nothing on package that says it changes color but Anker

charger looks exactly like the Tenergy one.
