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

Well, I have about 3 batteries for my Optimus 2X, and I'm managing of buying another extended one (3500mAh).
I have an external standalone battery charger which is the usual crap you'll find on eBay...there's no choice , they are all the same model

Now, the problem is that this charger, has a ridiculus current of 350 mAh +-50mAh
which is waaaaaay not enough to charge the battery in a decent time.
I mean the standard 1500mAh battery charges in something like 7-8 hours.
So the new extended one will take a full day to charge, at least this will not surprise me, considering the time it takes to charge the standard one.
So I'm searching for a wall charger that can charge batteries standalone... and that has a decent current I mean 800mAh or above.
It could be also integrated into a dock/cradle for the phone.....like the KiDiGi one (that should have a 800mAh current for the battery and 1000mAh for the phone), but it should have enough place to put an extended battery on it, which the KiDiGi one has NOT.
Hoping the community has some rabbits in the hat for me.
Thanks

thank you for your reply but it is the same charger i already have.
That specs are the specs for the USB output.
If you look into the photo of your link, you'll see that the battery itself is charged at the usual 350mAh....
the specs are the same of my charger....sadly
I should say thx to you, it was thinking of buying 1 to charge my extended 3500mah battery I just purchased from ebay
I just got my 3500mah delivered is charging right now in my phone
looking for a charging dock to
let me know how long did it take and if it was with phone off or on, and via wall charger o USB.
I ordered mine 3 days ago...
The battery was already charged to 95%, let it charge for 2 hours to be sure it is full, deleted battery stats now it's 5 hours ago and still 86% wifi as being on all the time, mail sync every 30minuts, and lots of Tapatalk, 30minuts of gaming,
Wen battery is empty I will full charge and let you now how long it takes

i put my phone on the charger with total empty battery (3500mah) on 11PM
at 7AM wen I waked up , the phone was full charged , so full charging overnight is posibble with the original charger
don't now how long it take in total , could not see because phone was total dead wen i put it tot charge , turned phone on in the morning and battery was total full
Thank you. So it took 9 hours with phone shutted off.
Less than 9hours I was asleep so don't know exact time

Quite expensive, but it outputs 1A
Good thing is that the adaptor is separate so you can use your own adaptor, maybe a 2A one.
But it looks shady cause the picture on the box doesn't look like Optimus 2X
http://www.dealextreme.com/p/dual-u...th-extra-battery-slot-for-lg-optimus-2x-73031 <-- if you're more comfortable with dealextreme
I went through the thought of getting a extra battery as well but the price and the extra stuff is just isn't worth it.
When i stop using the optimus 2x or if it dies i will have a almost useless cradle with useless batteries.
I went down the path of getting backup battery instead since i can use it on other devices. (the universal type)
http://www.dealextreme.com/p/univer...wer-port-green-white-flat-plug-110-240v-55661
EDIT: you can also get something like this but the output isn't great but you can use it for old phone battery and any battery which is 3.7V
There are a lot more like this, you can take your time to find the perfect one.

Thank you for your time!
Sadly none of them specifies the output current for the battery 4.2V @ xxx A
They only say that the usb port is feeded with the 5V USB spec voltage and the current of 1 A...this is the current that the phone receives and not the standalone battery. It's pretty easy to find simple wall charger to plug directly into the phone that will output 1A of current @ 5V.
The last one you linked seems to do, althought not explicited, 500mAh both on the USB 5V and on the 4.2V of the battery pins
Thank you in any case.

Most of such device don't regulate the current, usually just the voltage.
As long as the AC to DC adaptor can provide everything will go through (meaning the output current of the adaptor will be the rating going to the battery/phone or whatever)
And how much of it is used up depends on the device drawing power.
Note: you do have to beware of some made in china adaptors as the rated specs sometimes do not match up to the actual.
remaining on topic I think this could be useful 0.8A http://www.dealextreme.com/p/0-8-lc...-car-power-adapters-for-digital-cameras-41216
Regarding the 3500mAh extended battery this is the measured capacity after ONE cicle of charging/discharging from Battery Monitor Widget
I think this could be useful in the future, I will update it if the capacity increases meanwhile I charge/discharge it...at least for the few first times this could be possible.
Battery
I think the stock one is good to have ! No need to change !
My eBay charger works fine, charge time is long yes but it charges about as long as my battery lasts did I'm never running out.

yes but it is useless regarding the focus of this topic.
We are discussing about standalone spare batteries chargers.
I think it is better to charge your 3500mah (or 2500mah?) battery using a 2amp usb adapter. Charging a lithium battery at anything 1c and below is very safe. So if you're charging 3500mah (3.5amp) battery on a 1amp charger, it's only like 0.3c which is way less. Atleast if you use a 2amp charger, you can charge your big battery around 2hrs tops. But there is no desktop charger with 2amp output though, just usb adapters, mainly for ipads.
I think i find the correct rapid chargers for Nexus 5X, see photos:

Droid-life has an article showing that this charger gets close to providing the same amps as the stock wall charger. I'm definitely buying one today.

Could you check with an app like Ampere and compare numbers to the included wall charger? I'm guessing it's 2.4A and not the full 3A. Still faster than 2A at least but not the full potential.

Update 3: Last one for me, then it’s on to the engineers to try and give you even more clarity here. This morning, I started my phone at 40%, gave each charge up to 2% charge, grabbed a screenshot, then wound them back to 40% to do the next charger. Here are the results.
Idle phone: 118mA
Official LG USB Type-C charger: 2642mA
Aukey QC 2.0 PowerBank: 1241mA
Original Turbo Charger: 1314mA
Hikeren 5V/3A Thunder Charger: 1988mA
Samsung Fast Charger: 1961mA
Tronsmart QC 2.0 Car charger: 2511mA
I can't see 3A current in the original charger, but seems the tronsmart charger can give almost the same current as the original ones.

Interesting. The Tronsmart for them gave only 1.8A but could be because it was done at a higher battery percentage.
And I'm willing to bet that at very low battery (5-15%) the stock charger does 3A.

I just got my phone and I'm merely topping off the battery, but Ampere first gives an error in inability to gauge battery charge then asked to switch modes... then it only shows around 1A for the OEM charger. So not sure we are gonna get good reading from that app. I guess it's possible that the amps tapper off when the battery gets close to full, but there seems to be better testing involved here.

I believe I saw a video or read an article that explains that all fast charging tech basically works the same. The more empty the battery the greater the charge. As it gets full it'll be less. So topping off and only getting 1A could be right.

Full disclosure, @Tronsmart provided me a unit in exchange for an unbiased review. I've been using this charger for a few days on my Nexus 6 and have to say I'm very happy with it. I have a few Quick Charge 2.0 devices but also have a Nexus 5X and 6P on the way, so I wanted something that could handle any device. The Quick Charge port delivers, rapidly charging my Nexus 6 without any issue. The included 1m cable is very thick, as is the fixed Type C cable. My Nexus 5X showed up today, and officially it will not charge as quickly as the included 5V/3A charger the phones come with as this tops out at 5V/2.4A. That said, the fixed Type C cable registered as "rapidly charging" so while it may not be quite as fast as the 15W wall charger it's delivering enough power for the phone to indicate rapid charge. I'm very happy with this car charger since it offers both the old and new options until Type C becomes more ubiquitous.

For that price, you may as well try it. I will say though, the cable you use could make the difference and then there may be a handshake issue for it to get a full 3a charge. I think it is still very much unknown which type of car charger can provide the full 3a until they get tested. My guess is that you will need a true USB-C type that is also rated for at least 3a.

First review on Amazon is:
Cheap
Blew up (sparked, smoked), without even having anything plugged into it. Used it once.
There are a couple other reviews that say it doesn't charge at 3A.
I'd steer clear, but that's just me.
check the price here will definetely get one today!

Anyone read this?
http://www.techtimes.com/articles/9...-chip-and-a-soldered-usb-type-c-connector.htm
"The Nexus 5X currently does not have a Quick Charge feature. However, this teardown attests it is equipped with the ability to support the feature in the future, since it houses the Qualcomm SMB1358, Quick Charge 2.0 IC. Given the fact the 5X's USB-Type C connector is supported by Qualcomm, a possibility exists that this feature could soon be activated for the device."
Is that true? How to activate the quick charge 2.0 on Nexus 5x? can't wait for this, developer!!!!!
When I used the AmazonBasics Charger (2 USB ports, claiming up to 2A each) with an A to C cable my 5X says 'Charging Rapidly'. (Apologies for no links - new user account)
I haven't tried it with Ampere yet - I wasn't expecting it to say that at all, I was just looking to keep things topped off during my commute this morning.
Mailman just delivered the Tronsmart. Seems well built. It's odd that they chose to hardwire the cable to the charger rather than putting a female USB C port on the charger and then including a USB C double ended cable.

First thing guys i did not started this with a comparission in mind, i was just troubleshoting my phone but while i was testing all the chargers i have laying the house it seemed to me like a good idea to take note and share my findings. That said lets get to the problem:
Last mont (october 2015) i bought a new battery from official LG retailer it cost me Bs 12000 (Im from venezuela, crazy high prices for us), i did this because a part of my touch screen is dead and i read in several places that replacing the battery may fix that, well it didnt but at least i have a new battery. Anyway, the thing was super expensive, i also bought a LG "Original" Charger + USB cable at Bs 3000 from at respected seller, the Nexus 4 original oem charger fall from a table and died, it wasnt broke just didnt charge anything at all, thats why i bought a new one. I didnt pay much attention to the charging time until like 2 weeks ago, i was playing in the phone with the charger plugged and the battery was slowly discharging wtf?, since then ive been trying roms and kernel settings because i was to lazy to try another chargers until today. I was thinking about ROM and/or Kernel related problem since I updated to Android M about that time (2 weeks ago). So i didnt have idea if it was rom, kernel, battery or charger what wasnt working properly.
My phone setup:
ROM: Cataclysm Oct 27 2015 + SmartRadio Fix
Kernel: Hellscore b87-M (Hellsactive governor, row scheduler, DT2W and USB Fast Charge both enabled)
Method:
I used 2 USB cables, a generic no branded and a samsung one.
In developer options i enabled Stay Awake option so the screen will never go off while the phone is plugged.
I plugged the first charger with the generic cable and let the phone charging until it showed me the stimated remaining time for full charge, then i plugged the next charger (still with generic cable) and rebooted the phone, after boot i wated until it showed me the remaining time to go with the next charger, once i tested all the chargers i replaced the generic cable for the samsung and repeated the process. So i tested the charger twice, one with each cable, and yes i got the same results every time, so iguess this android feture is actually doing his job and saying the truth.
LG Original Charger - Not really original. Lited Output: 1000mAh
Samsung original charger, i bouth this one like 2 years ago like genuine, but is not. Listed Output: 1000mAh Now blury but i remember it was that amount.
Blu Charger from a Blu Jenny TV phone i have. Made touchscreen go crazy. Listed Output: 500mAh
Orinoquia Charger. Orinoquia is a brand selled by the goverment here in Venezuela. Listed Output: 550mAh
USB Charge. Straight from the back panel of my motherboard (MSI B75MA-E33, Windows 10 Pro x64)
Nokia Original OEM Charger. This is from my mom's Nokia Lumia. Listed Output: 750mAh
The Nokia charger was the only one that was actually delivering the amount of power that it says it should deliver. From now on im gona have a hard time thinking about wich charger im gonna buy. Dont buy cheap chargers guys and only buy them from the company itselft when possible or an authorized reseller. Sorry for my english
I always used a 2A Blackberry Playbook charger for my Nexus 4. Had it for three years and when I handed it to my Dad to use three weeks ago it would still do a day and a half normal usage.
Best charger out there. Still using it with my LG G4. Charges super quick.
Your USB cable can also make a difference.
You mentioned that you played with phone while it was charging...Its possible that you had lose contact at same time and cable was not supplying enough current for battery to charge. Just go to battery stats screen and it will show charging mode. If current being supplied is around 500 mA it will shows USB. This has happened to me on various phones including the n4. I usually just turn off wifi and data connnection and turn screen off while its charging and it really charges faster. ( better option would be to turn off phone). My charger is also broken (fell from wall socket on the floor) and it takes abut 3-4 hours to charge the phone.
I have also used friend's nokia charger and they are quite good. You can continue using it.. better use a 1.5 A or 1 A charger ( stock charger output is 1.2A)
I would also point out the Blackberry charger I use has a captive cable which reduces the connection issues.

Thanks ill try to find a charger with that output that actually delivers it.
My 0,05$:
I tried out a lot of chargers for both my nexus 4 & nexus 9 (tablet) and got by far the best results with Nillkin chargers & usb cables (you can by them cheap from banggood.com). Bought 4 so far (home-office-multiple devices): Very fast charge (much faster than original chargers included with both Nexus 4 & 9), very decent build quality, useful USB cable, charger doesn't make any humming noise, etc. Can strongly recommend.
after i had lost my original n4 charger, i used a motorola charger, which delivered max ~600mA or something. then i bought sony cycle energy wall charger CP-AD2. it is very cheap yet quite powerful. i suggest using currentwidget for checking charging speed. sony charger delivers min 700mA max 816mA (i think its the limit of the n4 since sony charger can deliver up to 2A)

Thanks for the suggestion ill try that app, didnt know fo his existence jaja
The limit is 1,5 A coz the orginal charger delivers 1,2 and there is always 300-400 mah tolerance

I agree.
I'm using a Samsung USB cable with my original LG N4 charger.
It charges twice as fast compared to the original cable that came with the charger.
However, I'm pretty sure it was okay before. Maybe the LG cable is not as durable as the Samsung cable.
Okay!! Yes it is true. I myself now use only the Xiaomi Redmi 2 Prime's charger. As it charges my Nexus 4 far more faster than the real charger.
So I got my VIVO XL yesterday, charged it, and used it for one cycle all the way to 1%. I have to say, the battery life was amazing on that first cycle and I was impressed. Phone on time was 15hr 11mins, screen on time was 6hr 41mins, all this on my first charge and at 50% brightness.
I was excited that the battery was at 1% and couldn't wait to use the "quick charge" to see how "fast" it would charge since I never had a device with "quick charge capabilities" before. So I plugged it in, and timed it, what a major disappointment.
Here are the results(phone plugged in at 1%):
1hr @ 43%
1hr15min @ 51%
1hr 30min @ 62%
1hr 45min @ 71%
2hr @ 79%
2hr 15min @ 86%
2hr 30min @ 90%
2hr 45min @ 93%
3hr @ 96%
3hr 15min @ 97%
3hr 30min @ 98%
3hr 45min @ 99%
3hr 56min @ 100% FULL CHARGE
4hrs to charge a phone
Anyone else experience this. This took longer to charge than any device I ever used/tested/played with. and is totally unacceptable. There is no information anywhere as to what this so-called "quick charge" is. When I first plugged it in to charge, it said something about check this box for DU quick charge. What is that? It said I had 18 minutes of quick charge available.
I did some digging around, and the device is supposed to be supplied with a 9V/2A quick charger, I was supplied a 5V/2A charger. I sent an email to BLU in reference to this issue. BLU might owe us all new chargers:silly:

thanks for the feedback guys
I've given up on getting quick charging on this phone. Since the phone has a mediatek cpu, it supposedly supports Mediatek's version of quick chargings (9v, 2a) which is called PumpExpress+. I bought a Meizu MX5 charger off of aliexpress which is suppose to support PE+. Even with the Meizu charger, I still onyl get 5v and 1.4amps max. I get that charge rate regardless of which charger I use.
I contacted Blu's support about this issue and they were extremely unhelpful. I asked if the phone supported mediatek PumpExpress+. I didn't get a straight answer, just a reply saying to only use the included charger. I asked if Blu is going to sell a compatible 9v charger for quick charging and they said no. I gave up at that point. Their support is pretty much useless. I like the phone otherwise though.
what are you using to read the charging volts/amps?
BLU cusomter service is probably the worst i have delt with in a while, and contacted the warrantu dept. They shipped out a 9v2a charger to(or so they said), it will be here friday. i will post my results.
you are the first person i heard that cant get a quick charge while using at least a 9v2acharger. maybe there is something wrong with your battery or charging port?
just installed Ampere to check the current. with crappy supplied BLU charger, it see 3.9v max and 1.2a max. Tried galaxy s4 charger which is also a 5v2a charger, results were almost identical; 4v max and 1.22a max

I used this this DROK usb watt meter. I don't trust ampere or any other app based measurements. Phones often have different charging profile depending if the phone screen is on or off in order to limit heat generation in the device. I've tried the Meizu charger with PE+ and a Qualcomm compatible QC 2.0 charger. Neither will charge the phone at 9v.
There was one other person on slickdeals who also could not get fast charging to work with a Meizu charger. I honestly don't think Blu enabled fast charging on this phone.
I would be super interested in your results with the charger furnished by Blu. Must've taken you quite a while to get them to agree to send you the charger. Props to your persistence!

Did you end up getting the 9v charger from Blu yesterday? I'm really interested in your results.
sorry for the late reply. needless to say, the charger BLU sent was a 5v1a. i called them back and they said thats the only chargers they give through warranty, and that they dont know why in was told id be sent a quick charger.
i bought this, and still only see 4v and 1.2a while charging. obviously it is not enabled in the device. can we say false advertisement?
https://www.amazon.com/dp/B019GQ6S2C/ref=cm_sw_r_sms_apa_09krxbC05ZDXM
i am going to file a report with the FTC addressing this issue as it is illegal.
That's really unfortunate. Blu does supply a 9v/2a quick charger for the Pure XL phone. The Pure XL also has a Mediatek processor so if any charger from Blu could give the Vivo XL quick charging, that would be it. If you make enough trouble for them, they might send you the Pure XL charger! I agree that Blu's ad is extremely misleading. I like this phone otherwise, but Blu's customer service is pretty incompetent.
^the charger i bought from amazon is a 9v/2a, so using the charger from pure xl wont make any difference. quick charge is just not inside the device, guess BLU realized at some point before production began that it would dip too much into their profits if selling the phone for $150usd.

The charger you got from amazon is 9v/2a, but it's based on Qualcomm's Quick Charge technology. it'll only work on phones with Qualcomm processors that support the Quick Charge standard.
Vivo XL uses a Mediatek processor. So Qualcomm Quick Charge chargers won't work on the Vivo XL. You'll need a charger that supports Mediatek's 'Pump Express' technology. http://www.mediatek.com/en/features/power-management/pump-express/
you cant buy that charger anywhere though, so i cant even test it. also, someone on another forum said they got a blu device to accecpt the qualcomm charger, actually, it was a youtube video.
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 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

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.

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
