LG G4, stock battery, quick charging 2.0 and AUKEY charger, is it a safe match?

Hi, I've recently bought a LG G4 and this certified 2.0 charger:

}
...it's still boxed and I've also found a thread here in XDA sayin it doesn't work on G4. For some reasons. I still haven't tested it. Yet the reviews of LG G4 owners on Amazon of this particular charger are all very positive.
ANYWAY
Prior to the LG G4 release I read a few articles that talked about a certain 3300mA battery that was Quick Charge 2.0 compatible.
This puzzles me.
THE QUESTION:
Do I need such 3300mA battery or a QuickCharge 2.0 special battery to *safely* quick charge my LG G4, or is the stock 3000mA battery ok?
(OPTIONAL QUESTIONS)
1) Is it going to damage my phone/battery in some way? Will the battery life get shorter? Will it overheat causing the phone/battery any damage?
2) How is it possible that a Qualcomm Quick Charge 2.0 certified charger does not work with the G4?
3) Could you suggest me a trusted, working charger, possibly under 15 euros?
Thanks for your time!

I think when you get people to say it doesn't work, doesn't mean it won't charge. It means that you won't get the additional benefit of quickcharge 2.0. AFAIK, the phone will still charge at higher amp (5V 1.8A), but will not charge at the QC 2.0 (9V 2A) standard.

Thanks for your answer. I still don't know what to think because LG-G4 owners' reviews on Amazon are all positive and satisfied with the increased charging speed.
What about the main question?

I use the same exact charger on my G4. It's great.
1. No damage, and your battery life won't be any shorter than regular charging. The QC is set to slow down after 60%, if I'm not mistaken.
2. Don't know who told you that it wouldn't work with the G4..
3. Who says you have to pay a lot for quality? It's a charger..

1. I heard 75% myself but either way it slows down.
2. The G4 seems to be finicky to what QC2.0 charger it wants to work with. There are reports of it not working with the aukey and reports of it working with the aukey.
3. Cheap crappy chargers can actually cause harm. If it's QC2.0 certified there's no problem.

I got [phone was off] 30% after 20 minutes
55% after 40 minutes
75% after 1 hour
then took 40 minutes for the remaining 25%, 10 minutes the last 5 percent alone.
Is QC2.0 working? I haven't ever measured normal charge percentages. It was a little bit hot in the first hour, then it cooled down.
I used the USB cable shipped with the AUKEY charger since the instructions say "please use the included cable for your non-iOS device" or something like that.
Should I keep using it or using the original G4 cable will make a difference?
Could you please suggest me a good (possibly cheap) QC2.0 certified charger from another brand that has a more... constant behaviour with the G4?
Thanks for your time

several days ago, i buy aukey multiport QC 2.0. From my experience, QC 2.0 does not give any advantage to G4, compare to original charger. It's need 102 minute from 5% to 100%. Stock charger need 105 minute from 5% to 100%. claim that's QC 2.0 will charge 60% for 30 minute, not proven using aukey. When i test using usb voltage and current tester, aukey using 9V. So i'm curious, is really G4 is qualcomm QC 2.0 compatible ? Yes, it's can use 9V for charging, but not get advantage charging 60% for 30 minute, and not much different from stock charging that only using 5V.
Something make me curious to, why other charger with more than 2A output, needed about 3hour (or more), compare to G4 stock charging (1.8A). Is this stok charging made spesial for fast charging too ? and G4 cannot get advantage from other charger, although it's have more than 2A output ?

My genuine Samsung fast adaptive charger charges my G4 about 20%+ faster. May be an Aukey problem.

I don't think aukey is the problem. It can charge at 9v, than regular 5v. But it not make it more faster than stock charger.
But for Samsung charger, yes, it can charged faster than stock charger, according to my mailing list friend. I'm not try using it yet, just order another QC 2.0 charger. LVSun 4 port charger, can be use for desktop or car charger.

I bought this one http://www.amazon.com/gp/product/B00ZZG6IKU?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00
and it does not appear to charge any faster than regular car charger i had before. Ampere+ reports 1375mA or so

I heard that LG G Flex2, G4, is compatible with the Quick Charge 2.0 tech. If the phone is compatible, it is safe to charge it with a quick charger. And my friend use the Aukey 10000mAh Portable fast charger to charge his iphone. He says the charger works well and I wanna try it.

I just bought a Tronsmart Quick Charge charger and it charged from 15% to 100% in about 1:15 hours while a Samsung 2.1A charger (the one that came with my S4) charges it in 4 hours from 10% to 100%

If it slow down it's useless, I need to charged my phone before I leave home, like I have 80% because I used it during morning, but before leave home I need 100%...

So I just charged my phone with the original charger for the first time and it is actually giving me Quick Charge 2.0 speeds. From 27% to 67% in 40 minutes which translates to 1% every minute.

AUKEY Fast Charger ... Works great
I have the Aukey Pa-T1 5 Port Qualcomm 2.0 Certified Charger. It does charge faster than stock LG Charger. Generally, it seems to charge 1% or more per minute but slows down after about 80% charged. I have been using the LG Stock 3000ma batteries with the charger. Aukey guarantees that the charger will not harm the battery or phone. There is a special circuit inside the charger to regulate proper charging. The only way this charger won't work correctly is if you have a knockoff battery or cheap cable.

I have aukey 3 port usb quick charge and it is much faster than original LG one. Almost 3 times faster!

Must be something wrong with your stock charger or cable my aukey charges from 10% to 100 in about an hour stock charger is only about 20mins longer. I have 815 korean variant

I used same cable. As I know LG charger does not have quick charge, maybe that is the reason.
Anyway I use LG charger for raspberry pi now

Quick Charger 4.0 wall charger

Hi guys, anyone here are using QC 4.0? If yes, can you tell me where to buy one good?
I'm looking for QC 4.0 in chinese sites, but it's hard find there,

You could try the official Razer phone charger. That has QC 4

I saw the Razer Charger, but found in on site only, like 40 eu.
I can't find any good review with QC 4.0, they are all QC3.0 and i don't know why :/
any clue?

i had a QC4+ adapter some weeks ago bought from amazon
https://www.amazon.de/helpers-lab-L...F8&qid=1538499272&sr=1-2&keywords=helpers+lab
there is absolutely no difference between QC4+ and a normal QC3.0 adapter.
I've send back the QC4+ adapter, by the way, Power Delivery 3.0 is 100% compatible with QuickCharge 4+. I've a power delivery powerbank and they can charge my phone on the same speed as a QC3.0 or QC4+ charger. I have compared all adapters and there is no advantage of Quick Charge 4+
With QC4+ adapter the phone charge on maximum 3300 mah ~17w
this is the same i get with my QC3.0 adapter and my PowerDelivery Powerbank.
Spend your money for other thinks as a expensive QC4+ adapter

Thank you very much for your answer, i was looking like crazy on youtube about QC 4.0, but didn't found anyone using.

I think mi8 hardware support qc4.0 but the software for qc4.0 to work still not activated... Probably kernel related

It's not just speed that improves with each version, it's also efficiency. Less power drawn to charge at the same speed = less heat.

Good that you say that....
I forgot to mention that the QC4+ charger getting very hot in both situations, in IDLE and when Charging a phone. You can read the same phenomenon in feedbacks of the charger I mentioned from Amazon.
I stay with it, IT IS NOT WORTH the money you've to spend for a QC4.0+ charger, there is absolutely NO Advantage to buy it. I've tested for myself and this is just my opinion.
and as i said, its more useful to buy a PowerDelivery 3.0 charger instead a QC4+ charger because PD is 100% compatible with QC.
Here is some info about it:
Quick Charge or Power Delivery
It seems that PD can deliver a much higher power output, but actually most smartphones do not need more than 18w charging, that’s why Qualcomm’s Quick Charge is widely adopted by most of smartphones, while Power Delivery as a standard that anyone can use is more designed for larger devices like laptops and household appliances.
What’s more, Qualcomm announced Quick Charge 4.0 in 2016 which is compatible with Power Delivery. In other words, Quick Charge 4.0 has simply learned to speak PD language, but still does the same thing as Quick Charge 3.0 with a few upgrades.

I bought Razer QC 4+ for my Xiaomi mi 8, but when I plug it to my phone, there is no Quick charge icon(round with thunder) and on lock screen no any text with "charging fast". Why? I can't understand

No, but I read a lot and understand, that qc4 + support PD 3.0 and it give maximum 2800mA and charges by 2 channels. And we have fast charging with 12 v and 1.5A = 18 W, thats why we have no hot battery. With qc 3.0 we have 3700mA, thats why we have hot battery. And Miui qc logo appears with 3000mA and higher. Conclusion - QC 4+ works with PD technology

Can you try after updating to 10.3.1.0? I did and now PD charging is also marked as quick charge (text and lightning icon too). Using a (hopefully) PD3.0 capabke charger (Blitzwolf BW-PL4 45W). I also has a Baseus QC4.0+/PD3.0 car charger, but I can't figure out which protocol is working as the phone is compatible with both and only the Type-C port of the charger provides both.

I measured with Amper meter with Razer QC4+ 24w charger and Helper 45 W PID 3.0 charger. It's start from 2870 mAm and grows to 3300

Sadly I don't have any QC4 charger, but here is the original Mi8 Charger and cable charging graph.

Thank you guys. This is almost identical to my 18W QC3.0 and 45W PD3.0 charger (tops at 3400mA).

According to this gtrusted article,
The Xiaomi 18W QC 3.0 Charger supports the same power profiles of 15 watts (5 volts @ 3 amps), 18 watts (9 volts @ 2 amps) and 18 watts (12 volts @ 1.5 amps),
[...] with its battery fully discharged, we could see charging initially went up to around 16.7 watts (6.2 volts @ 2.7 amps) which later dropped slightly to about 15.4 watts. The current pulled continued to decrease along a 5 volts rail towards the end of charging to eventually settle close to zero when the battery was almost full
Click to expand...
Click to collapse
However, if using a PowerDerlivery 3.0 charger, we could benefit from Mi 8 support of 27 watts (9 volts @ 3 amps), and 27 watts (12 volts @ 2.25 amps) for charging.
I am after am AUKEY charger that is capable of switching between those voltages, which is called PDO. And according to that it is possible to charge 50% battery in 30 minutes.
Our Mi 8 phone has been tested to support this PDO profiles:
7.5w (5V - 1.5A)
15w (5V - 3A)
27w (9V - 3A)
27w (12V - 2.25A)
As such: QC4+ = PD3.0 + PPS + QC3.0

It sucks, but that's most likely the reality. A 100w USB cable is widely available from online retailers and is the closest you'll get. 65w GaN charging is very fast too, only maybe an extra 5-10 minutes to charge.

iam looking for that too, my phone stop charging 120W turbo max, taking +1hr to fully charge

I have a 120w baseus gan charger, but it only show quick charge when charging

After 1 Week :/

Mi 10 ultra -i buy baseus gan 2 pro charger. I use type c port 1 , not get full potential. Use cable 100w E-mark chip cable. I think Xiaomi control other charger, not get a full potential. Only get quick charge or mi turbo charge (low output)
But use Xiaomi 65watts gan charger.(Mi11)
Wireless charging get full power 50w max charging.
Wired charging to phone get approx 36-39 min to 100 % full.
Mean xiaomi enable super charge turbo max- Xiaomi chargers and cables only.
Anything i am wrong, reply correct thing.
Baseus Gan 2 pro was good option, because it have 2 type c -65watts each. 1 usb -A 60w
Type C1 connect, wireless charger. 65w
Type C2 connect direct wired charging. 65w
Usb -A 60 w . Use other devices.
But xiaomi killed this option!

Question 100w same as 25w?

hi with my ultra i got a free 25w samsung charger
i bought a 100w ugreen charger :

do you know what is happening here?

I don't have any information to illuminate what's going on, but this sounds familiar enough that I think at least one or two other users in this section have reported something similar. Me, I try not to quick/fast charge any more than I have to, and I keep my battery between 25 and 75%, so I don't pay that close attention.

I haven't used Ampere. I assume the top is the charging current? The one on the left shows a higher current, 5.58 amps, vs 4.40 amps. Higher current for a given voltage means more power is being transferred, thus a higher charge rate...but even 5 amps is pretty high. That's why fast charging schemes use higher voltages, because a given conductor can usually handle a higher voltage better than it can handle a higher current.

The Galaxy S8 is advertised to be able to charge at a 45 watt rate, max, so if this is true, a 100w charger wouldn't charge any faster as both devices would negotiate a max of 45 watts. This is assuming both the device and the charger limit the charge current; I imagine many devices will draw more power than they're rated, and many chargers will try to supply it, although the load might pull the voltage down.

Probably because your tablet can't charge at a rate any higher than 45W - 15v @ 3 amps.

That is correct it can only take 45w so 100w won't work. It will only limit the 100w charger down to 45w

You shouldn't look up what a USB port can take. It also depends on what main board and battery can take. In this case s8 ultra is limited to max 45w. So your 100w charger won't go 100w on this tablet because it does not support it.

the charge circuits are limited to a max input wattage and voltage. to protect the device from being burnt out. it is not like the good old days where you could pump as many watts and volts you wanted into a device hoping that you didn't burn it up, blow the fuse or a diode. now everything is limited to a max input. a lot of it has to do with the brand x / universal chargers being sold. that claim they charger faster when really they don't.

The question is not about 100w
it is about 100w doing 45w vs 25w charger and same time charging

I don't know. They're both charging at about 5 amps which is honestly pretty high. Nothing indicates the actual charging rate in watts because it doesn't display the charger voltage. I will say I'm rather skeptical of strange off brand Chinese tech so it's possible you'd get better results with a different charger.

Question is neither is showing super fast charging 2.0

Fast charging is on in settings. It shows super fast charging but not 2.0

I got the same issue with my s22 ultra...The charger must have the right specs and the cable must be 5a. If not, you won't get super fast charging 2.0. This will only give 25w fast charging. I have a 65w ugreen charger that has all the right specs...It has 65w max on 1 port and when other devices are connected on the other ports it distributes the 65w over the ports. I used the cable that came with the tabs s8 ultra and got the same as you, not charging to it's full potential. Bought a ugreen 5a cable and now it shows super fast charging 2.0 on my tab s8 ultra and s22 ultra. The charger and the usb cable must be 100 % correct, otherwise you won't get max charging speeds.

i have the ugreen 100w charger with the 2m pd100 5A cable ( it says 5A in the end of the cable ) that came as a pack in ali but not seeing super fast charging 2.0.

Mine was exactly the same. Bought a different ugreen cable and the 2nd cable worked. Dont know why it worked. Looks the same as the one that came with the charger, just a longer cable

The cable makes absolutely no difference in the actual charge rate. Being rated for higher current just means the conductors are larger.
When you connect the device to the charger, the two negotiate a mutual rate.

Superfast charging + emark cables -- are they needed?
So I have a 45W charger, thinking about purchasing a 65W charger. I know The Tab S8 Plus only goes to 45W. My question: are there any advantages to using an emark enabled cable? I'm getting super fast charge notice with a 60W cable, no emark...

If you have a normal 5A cable, all PD charges are throttled to 25W (or less). Your tablet (at best) will show "Super fast Charge" and you will see something like 5A @ 4.12V when running Ampere. This is the power going into the battery -- the PD Charger is probably delivering something like 4A @ 5V. Around 20W going into the battery. I assume the "missing" 5W is powering the tablet - i.e. Ampere only shows what is going into the battery.
To get more than 25W, you need special "e-mark" chipped cables. These allow current higher than 5A to be delivered. They will be generally be rated by power -- 100W -- not current. I use
https://www.amazon.com/dp/B09G5XQG3T
This will allow the PD charger to run higher than 25W and you will see "Super Fast Charging 2.0" for charge status.
When I use the 100W cable, the tablet charges iin "Super Fast Charging 2.0" mode, and Ampere tells me the battery is receiving 7A @ 4.12V, or ~ 30W. Because I'm using the tablet at the same time I again assume some additional power is going to powering the tablet -- but that Ampere is only showing what is going into the battery. So maybe this bumps it up to 35W total. I have 45W and 65W power delivery bricks, so I assume the ~ 35W-ish delivery is being controlled by the tablet.
Note: The cable "in the box" with my Tab S8+ was NOT chipped, and was limited to 25W.
take care,
Joe

Best Charging adapter and cable ?

So when I bought the phone I didn't get the Original charger that come in the box.
I have been using a Ugreen 20W PD+ Ugreen PD cable.
But the charging patterns are very weird. Sometimes it changes at 4000mA, sometimes 2500, sometimes 1500, even 500mA.
Can anyone explain and suggest the most suitable charger with fast charging?
I'm using Docomo L-51A version

I highly recommend the Belkin 27 watt USB C charger. What makes it A Cut Above the Rest is that it not only has Qualcomm 4+ fast charge but also PD 3.0. This means that it supports Wireless fast charge accessories unlike most USC-C fast charge adapters which only have PD 3.0. It's only $11 w/ free shipping right now on ebay. And it's Belkin so it's made well.

For $12 you can get one with a high quality 1M usb cable.

Another accessory I recommend to everyone, is a magnetic detachable USB C cable, These are upgraded design that have a very strong magnet that does not accidentally detach easily. It supports PD 3.0 & QC4+ fast charge & data transfer. Using this cable will significantly reduce any wear on your usb c port. It swivels 360° so at any angle you can use the cord and it won't put strain on your phone.
I use it so that it is plugged in to my one port USB C wall plug and I can switch out and plug in any device (usbc , micro USB, iPhone). When my phone is done charging I'll plug in my 18650 battery charger or I'll recharge a flashlight or I'll even plug in my tablet all using the same cord. Very very cool. It comes in 1M & 2M length. It only comes with 1 magnetic attachment( your choice), so you have to buy more if you want to use more than one device, but it's worth it.
