To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the LG V30 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
Honestly I feel like this is not quick charge 3.0 even though the 835 processor and the device supports it. The charger that comes in the box is only 1.8amps output. Compare that to 2.0amps output with my Galaxy S7 charger and even 3.0amps output on my Nexus 6P charger. So it's not really more than the standard 1.5amp output of most cell phone chargers today and less output than other chargers that come with quick charge compatible phones.
Over all it takes around 1 hour and 20 minutes to charge it from 20% to 100% with the charger it comes with. Keep in mind that's if you're not using it while it charges. If you are using the phone while it charges on about 70% brightness, then about double that time to charger from 20% to 80%. I might try with the Nexus 6P 3.0amp charger later to see if it makes any difference.
So right now I give this only a 6 out of 10 for charging. So 3 stars.

Ran my phone down to 3%. Hooked it up to my QC 3.0 charger. Doing a timed 60 minute charge, I unplugged the phone at 82%
To be honest my last phone was a note 5 I just upgraded to v10 an I personally think that it charges just as fast, I put my my old samsumg fast charger to my USB-C an it registers at fast charging, charges while I play mmorpg, so GG I'm happy

I only tried it with a Samsung Galaxy S7 charger, which is
2.0 amp output instead of the stock V30 charger at 1.8amp output. So slightly more output.
It looks like no matter what charger you use above 1.8amp output, then the V30 is still going to only use 1.8amp charging rate. I think the phone is programed to limit it. Which is sad because I do not think it charges quite as fast as my S7 Edge.
When I plug the stock V30 charger with the phone at 5% it gives me a ETA of 1 hour 46 minutes. That seems awfully long time for quick charge 3.0 on a battery that is only 3300mah. It should be about 20-25 minutes LESS than that I think. According to LG it should be faster from their graphic at the release show of the V30. See attachment.
Although its possible a future software update could fix this though. So lets hope. I also might reach out to LG and ask them about this.

The little lightning bolt with a circle around it? Yes.
It also says "fast charging" in the notification instead of just normal "charging" when I plug in a regular charger.

Don't have a V30 right no, i've just compared the speed with the one seen on my G6, a 5-10% i have 1:50 for full charge without QC, for V30 you'll have to wait someone else...
quick charge feature is available only with original charger or by using power bank too ?
The Galaxy S7 adapter charges only at 9V/1.67A, for 15W of power.
The LG should come with a 9V/1.8A, for about 16W of power. Also, it may only quick charge with the screen off. It will drop to 5-10W with the screen on.
ummm...you should always check the voltage, not only the amps... (voltage multiplied by current equals power).
the best way to check is by using one of those USB thingies which measure V and A.
I'm pretty sure that v30 comes with qc 3.0 charger, so it definitely is a fast charger for that 3300mAh battery.
If I am not mistaken, the supplied charger is Quick Charge 3.0 compliant. But LG limited the charging to just 9V/1.8A, for total power of 16W.
The estimate on my v30+ at 7% battery is 1 hour and 43 min. In 15 min it charged 11% only.
Definitely slower than the galaxy note 4 I had previously.
The charger mine came with is 3amp and takes 45 min to fully charge

Ok I'm not saying you're bullshittin', but 3A gives 3Ah per 1h, or 3000mAh in one hour and since the V30 has 3300mAh battery, it must take over an hour to fully charge (even if it charges max speed constantly 0-100%), so yeah you're bullshittin'.

Yes! Very good point! What I have found is that it does charge pretty fast with the stock charger when you are NOT using the phone at all. Charges around 45% in 30 minutes from my testing. So pretty good!
However when I'm using my phone it takes about double the length of time. About an hour to get the same 45%. So I did a test to see what the heck was going on.
First I bought an Anker quick charge 3.0 18W adapter. So it is rated 2 watts higher than the stock LG charger. The Anker charger has output ratings of
3.6V-6.5V / 3A, 6.5V-9V / 2A, 9V-12V / 1.5A
I also bought a nice braided JSAUX cable rated up to 3Amps to make sure I am also using a cable that does not restrict the charge flow.
My results are about the same with that charger and cable despite it being rated 2 watts higher than stock LG charger. About 45% in 30 minutes when not using the phone and about 45% in 60 minutes when actively using the phone.
I also used an app to measure the charging current when not using the phone and when using the phone, and you are right. LG is for some reason limiting the Amps to only about 1.2A and 5V when using the phone, but then about 2.4A and 5V when not using the phone. I never saw the voltage go higher than about 5.1V. Assuming the app was accurately measuring the charge.
So I guess LG limits the charge when the phone is in use to keep the battery and phone from over heating while processor and display is working more? If so, it's obvious to me that they limit the charge while the phone is in use a good bit more than my 6P or S7 edge did. Hopefully with the upcoming Oreo update the charging rate is increased a little while the phone is in use.
When I had the phone, I measured with a USB meter. I was using a charger that's similar to your Anker, up to 18W.
With the phone or screen off, it charges at 9V/1.8A.
With the screen on, it charges at 5V/2A for 10W. But depending on what you're using the phone, eg. Watching videos or playing games, and your screen brightness, the effective charge is likely lower than 10W.
Since then, I've always developed the habit of not using my phone while charging.

i have had the V20 for about 12 hours in which time it charged from about 50% to about 75% ... my Note would accomplish the same in about 15 minutes ... and yet the V20 is supposed to run the same type of quick charger on the same size battery ... something about this doesn't rub me the right way
yes i did use the phone and unplug it a few times etc but it still should have been much faster ...
it was connected using its own cable and charger BUT through a USB extension cord ... so then i thought maybe that's the problem - maybe i need a longer type C cable and to get rid of extension cord ... but i need to have an answer to that BEFORE buying new cables ...
so i plugged it in directly ( no extension ) and tried to see if it charges in correct mode ...
and here is where i face plant into a wall of excruciating stupidity ... every single app out there measures charging current, whereas what i really want to know is whether the charger is running at 5V standard voltage or using the quick charge 9V voltage ... amazingly there doesn't seem to be an app to show this - or is there ?
my galaxy note would simply say " adaptive quick charger connected " when plugged into quick charger but the V20 doesn't say anything like that.
accubattery app says my screen on charging rate is 760 ma and screen off is 1760 ma ... and the charger of course states 1.8 A so that's consistent ... but is that at 5V or at 9V ? the charger supports both - which one is it ?
this is killing me - so much stupidity. it shouldn't be that hard to figure out whether the phone is charging correctly or not.
anybody have an idea how i could find out whether the charger is actually stepping up to 9V without physically cutting the USB cable and using my multimeter ?
EDIT: i realized i have a kill-a-watt ( actually two of them ) and i can measure power draw from 120V outlet ... so i did that. the draw fluctuated from about 6 to 13 watt. now if we assume 90% efficiency on the charger then full power would have to draw 18 watt from outlet - clearly it never got close. on the other hand at 5V it should have maxed out at around 10 watt power draw, and it went quite a bit over that so it would seem to be using the 9V mode ...
at this point however i'm up to 90% battery and can't expect it to charge at full rate any more as some battery charging algorithms taper off above 80% or so ...
i tried with and without extension cord and noticed no difference ... also if i remember correctly my Note also charged fine over this same extension cord ... but i'm not sure
EDIT: played with turning off 2nd screen as well as shutting down device completely - this phone is crazy. power draw is all the place - at one point it went to ZERO and stayed there until i unplugged it and plugged it back in, then it would fluctuate between zero and 14 watts ...
you know back in the day i had LG Nitro HD and it had worst battery performance of any phone ever ... and this V20 seems to be living up to that legacy. WTF.
anyway, it seems the charger and the cable and extension are not to blame - it seems there is some kind of software weirdness that is resulting in very sporadic power draw ...
slow charging is one of the reasons i switched from iPhone back to Android - i expected this V20 to perform similarly ( blazing fast charging ) to the Note 4 i had before the iPhone 6S Plus ... but it's charging performance so far is almost identical to the iPhone - slow as a snail.
i already spent $80 on case and screen protector and i'm supposed to spend a bunch more on extra cables and memory card as well as sell my iPhone and at the same time i'm thinking - maybe i should just return it ? going to have to observe it for a while longer before making any decisions either way ... terrible.
The V20 is QC 3.0
The Note 5 is QC 2.0
The V20 will negotiate with a 3.0 charger to tell the charger what power it requires at that moment so power will fluctuate during charging.
this will show you which devices are 3.0 and 2.0

yeah it fluctuates a lot. i gave up on apps and just using Kill-a-watt now which is a physical power meter you insert into 120V outlet. it shows power draw from charger, not output, but we can assume about 90% efficiency from input to output of charger.
i let the V20 drain to 40% overnight and restarted the test today. with the extension cord it went up to 16 watt draw from outlet and stayed there - charge quickly went up to 55% then i tried without the extension cord and now its only at 11 watts. this is with both screens off. so far my conclusion is that using an extension cord makes no difference but the level of charge on the phone does impact the charging speed. you need to drain the phone to measure full charging speed.
i will continue with my testing but i am somewhat relieved. 16 watts is close to spec, in fact the spec is 16 watt but on the OUTPUT side of charger, not input, so i'm withing about 10% of spec.
i'm also a lot less nervous buying charging cables now that i verified 16 watt charging over many years old USB 2.0 extension cord ...
EDIT: wow it went from 55% to 68% while i was typing this message ! this is very different from what i saw yesterday ... it was running at 11 watts while i was typing. looks like the phone charges fast as long as it is: 1) drained and 2) left alone. if the phone is almost full and you keep playing with it the level of charge barely changes.
EDIT: at 89% charge it's now down to just 4 watts power draw from outlet ... 25% of what it was pulling at 40% charge. so far it looks like it tapers charging speed off gradually with charge level - starts early and tapers it off to almost nothing as it nears full charge ... and all the while it fluctuates with processor and screen use and probably other factors such as temperature. maybe the reason it went to 16 watts when i plugged it in the morning is that the phone was cold from not being used all night and perhaps it now warmed up so the power got tapered.
maybe i'll stop testing it - it seems to be working correctly, just not the way i originally expected it to.
overall i'm disappointed with this phone but the only phone i would trade it for is Pixel XL 128 GB Very Black which is unavailable ... so i guess i will keep it.
the phone i'm most impressed with right now is ZTE Axon 7 i got for my mother - it is shockingly good - if it wasn't for FM radio, IR Blaster, Removable Battery, Laser Autofocus, Dual Camera, Dual Screen and Nougat i would even say the ZTE Axon 7 is BETTER than V20. the main problem with ZTE is it's just not expensive enough for my ego - otherwise it is great. the screen is is super sharp, vivid and punchy, the front facing speakers are loud and crisp and then there's the 2 year warranty. i'm jealous ...
but i will stick with V20 to protect my dignity. because let's face it - if i'm out on a date i want to have the latest, most technologically advanced and most expensive phone - not the cheapest phone, even if it is just as good or better. really happy with my decision to get Axon 7 for my mom though. she loves it as well.
The way QC works is that it will charge fastest from low power until around 70-80% and then slow down A LOT to help preserve the battery. That is why you saw a high wattage and then when you got into the 80's you saw a very low wattage.
QC is mainly for you to get 40-50% of battery power in a relative short amount of time when your battery is low.
I bought a little device that measures the voltage and current of the charge. And I'm using my own Quick Charge 3.0 wall charger.
When the screen is off or powered down, it charges at 9V/1.8A max. Resulting in about 16W of power. Which is pretty much what the supplied LG charger delivers.
When the screen is on, it charges at 5V/0.5A
My QC3.0 charger is capable of up to 9V/2A and 12V/1.5A, 18W of power. The V20 doesn't seem to draw that much power. And now I'm starting to doubt the V20 is truly a QC3.0 device.

I was getting 9.2v @ 1.67A = 15w of power. This is the max that my USB multimeter can do so it would seem that this charger is good for QC 3.0 as it did fluctuate voltage as needed.

That is still wasteful use on a battery and giving the next guy a raw deal. But to each his own. I try and make everything last and more efficient so the next person feels like they are truly getting an almost lightly used phone. If I sell my note4, they're going to get a lightly used battery on top of the 3 extras, with fixed GPS and better reception and cleaned out USB port with no oxidization. Same with my HTC m8 though that was only used as daily driver for two weeks and then a DAP for trips and occasional home use. Definitely selling the m8. They are basically getting a lightly used phone and the battery should still have some good life coming out of it. And personally I think jump is overpriced leasing but I guess you can drive it like you stole it. I prefer handing down the best experience I can to the next person.

Just tested this one at work. Phone was at 28% and I had been streaming Youtube for a good 2 hours before doing the test.
Ended up pulling 9.17v @ 1.68A = 15.40 watts (again maximum that my tester can do).
I'll be ordering a new tester that can handle up to 25A and testing again to see if I can pull the max 18watts of power that the QC 3.0 chargers says it can deliver

I see.
This looks like a good device.
There are time on my v10 where I'll plug it in and it will charge at a reduced rate so I have to unplug it and plug it back it and it changes to fast charge, that's just been my experience. This is using factory plug and adapter too.
So you might want to make sure the phone says "fast charging" and not "charging".

Is it just me or the S8 charge slow. I'm coming from a Note 5 and it charges pretty damn quick. Right now I'm at 53% and the phone says approximately 55 minutes till full.

That sounds about right.
Fast charging is great when the phone is at a low percentage, as the percentage increases the charging speed decreases.
Overall charge from 0% should be 1 hour 30 minutes -ish or somewhere in that range.
Test it.
It definitely charges slow, my 8+ included. There's a conversation about it on the Samsung support forum. It's definitely not intended behavior, as it'll still charge slow at low percentages. It never reaches the 2000mA rate that it should.

Based on my testing (I'll verify again tonight with pictures)
Quick charge 2.0/3.0
Screen on - 5v/1A
Screen off 9v/1.67A
USB C cable charging
Screen on 5v/1.5A
Screen off 9v/1.8A
The phones are QC 2.0 which means they're limited to I believe max 18 watts charging rate which would be 9v/2A with the screen off

2.0? Like the s6? Mine charges so much slower than my old s6. Took over 3 hours to charge 50% yesterday, screen off almost the whole time.

Yeah Samsung for some reason did not activate QC 3.0 or even 4.0 on the S8(so stupid but seeing the NOte 7 battery issue, they're probably being cautious)
The S6 only had a 2550mAh battery vs the S8 that has a 3000mAh battery so yeah the S6 is definitely going to charge "faster"
Pick up a USB C multi-meter and see what the charger is outputting to your phone
This is the one I bought (I am not affiliated with them - just showing which one I purchased)

3 hours to 50? Are you using the brick in the box? cable from the box?
That is not normal.

Stock brick and cable. The same thing happens with the brick and charger included in the wireless fast charging, and the wireless fast charger itself.

Both are enabled and while charging it says it's fast charging. It even gives a reasonable charge time like 52 minutes, but even the estimate is off by a lot.

Has anyone found and tried USB-C cables that support high-power 5a and for sale in the USA? https://www.startech.com/ca/Cables/usb-c/usb-c-usb-3-1-cable-power-delivery~USB31C5C1M
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Redmi Note 5 Pro can charge. A higher rating indicates that it charges extremely fast.

2 Hour With Stock Charger
I didn't completely check the ratings and time but stock charger DOES NOT fast charge this phone. as the Stock Charger isnt QC2.0 Supported. However this mobile does support QC2.0 but you'll have to test QC2.0 Charger 1st. Not all QC2.0 Chargers work on this mobile. Its a little picky. So go to a shop check QC2.0 Chargers on your mobile. when you get circle Sign on notification bar along side battery then it means that device is fast charging. if not then there will be no circle around the charging sign (Flash sign)
also idt this mobile supports QC3.0 but i dont have tools to check amps volts of charger.
Lenovo's original QC3.0 charger doesnt work on this phone. I've tested. but Motorola's QC3.0 Charger works fine.
my rn5 pro , takes apporx 3 hours to charge completely!
So far I'm a bit slow, a little bit more than 3 hours to completely charge the phone. Might have something to do with the cable.
My current charging setup:
- ANKER 5 port 40W
- a docomo USB cable
Planning to buy a proper 20AWG usb cable and a QC2.0 adapter.
I just bought a Letv charger which supported qc3.0 for about 4$ on taobao
I'm currently on the 9.5.11 build and it takes about 4-5 hours to completely charge the device using stock charger, And it took about 2-3 hours while on 9.2 build.
I wonder if the Mi QC 3.0 based charger would improve the situation for us?

Slow charge is a known bug in 9.5.11 build. Wait for an update or change ROM
13,2W for me
I recieved 9.2.13 update yesterday and have been noticing significant boost to charging speeds since then...yet to fully charge from 0 so can't comment on total time but as per Ampere, charging speeds are in range of 1500 to 1700 mah
1000 mA max with 5v 2amp and Work Normal Speed with Stock Charger
Approximately 2 hour for charge phone
I use the app Ampere (free in Playstore) to measure power input and with a normal charger (non QC) it shows up to 1600 mAh charging amount and from almost 0 to 100% it is taking 2,5 hours. One question: is there a way to tell if QuickCharge is active?
@Kusie
Look on your"s phone status bar. With normal charging there is thunder icon next to the battery. With QC active, thunder in in circle as far as I remember. Info about active QC should be also displayed in the bottom of your lockscreen

Using my usb inline meter, i'm getting ~6.5v and ~2.2A, with a Tronsmart usb cable and QC 3.0 Truro charger, screen off and about 44% remaining on battery. Will try when the battery is lower some other time.
takes around 2hours to charge 100% using stock charger..

I have no idea why would you do that... But read reviews, no matter what kind of charger you use, this phone only supports qc 2.0 version. From 0 to 100, in 1 hour, you only get like 55%, and in the end it slows down even more, so yes, impossible to fully charge in 1.5h, TECHNICALLY IMPOSSIBLE. You are either lying, or mixed times and got confused. Judging by technical parameters, the best this phone can do should be around 2hours from 0 to 100.

I just posted above that I was able to get QC 3.0 charging rates. Approximately 2.2A (fluctuates +/- 0.1A) and 6.6v (fluctuates +/- 0.2v) using a QC 3.0 charger and Tronsmart cable. Measured using an inline meter, not software.

takes about half an hour or so as far as I can remember 8/10
Charges really fast, thanks to 18W charger. Although on cable connected to computer, very slow

You compare 9v 2A(18w) vs 5v 0.5A(2.5W) PC usb? ...obviously it's slow with a pc charge

From mathematical standpoint 30 mins for 0-100% is impossible with 18W charger, let me make it a bit clear
It has a 3.800mAh battery or 3.8Ah for short, which means if it had a 5v 3.8A charger it would take 1 hour if the charger and delivery system(cable+chips inside phone etc) were delivering 100% efficiency. Now 5v 3.8A is 19W charger. For half an hour we need 5v 7.6A or 38Watt.
According to Quick charge which is present in this phone it can be charged at 9v 2A or 18W, so even if the phone has 100% efficiency it would take a bit more than 1 hour to complete 0-100% but because each system can't deliver 100% efficiency calculate to 1hr and 1-20 mins give or take
P.S. half an hour, wish but ain't possible unless we have 9v 4.2A charging with 100% efficiency(or 5v 7.6A if you prefer) - Still going to get this phone soon(if price drops to my desire)
Just charged 25% to 100% took around 1 hour
I have here the test i made 100% to 11% took 6h34m SOT, charging from 11% to 49% took 25 minutes from 11% to 82% took 59 minutes, from 11% to 98% took 1h36m.

Just got it yesterday...
Drained it fully so it died...
Then 0 to 53 % in 35 mins flat...
I think the last 10%( from 90 to 100} takes a big effort.
Just tested with LG V20's Fast Charger of 18W.
Fast charging works. confirmed.
But not with OnePlus 3T's Charger.
Will check the same with 5T's Charger and Update.

Yes OnePlus 3T, 5T does not work.
Also I was charging N7+ from 18% via LG V20's Charger and it got overheated and started malfunctioning. But thankfully there was a circuit breaker and protection circuit in LG's Charger which saved it. Device is working fine too. Now I am using the nokia charger provided in the box as none are working.

So that means if something happens to the current charger provided with the phone, we will have to buy a Nokia branded charger and cable or there would be issues. Hmm

I also meet this using oem cable. With nokia original cable is no issue.
I just got this device Thursday not a Dual SIM device
It charges fully in about 1hr and 30mins of charging adds quite a bit of power to the battery
if we use a PC it takes ages
is it safe to use fast charge daily?
Can we charge the device by a standard charger having 5v 1 amp rating with the USB type c cable plugged into it?

Yes, i use mine from a tablet at 5v and 1.5A. You can use any charger if it is 5v or if it is turbopower o fastcharge.
I also use my old LG's charger. 5v @1.8A. Im not really that into charging speed. One thing i noticed is that on both chargers when reaching 100% it says charged but still charges for another 15minutes before the charging icon (flash) disappears from the screen. Has anyone else noticed this?

Not the absolute fastest around, but damn sure not the slowest... especially when you consider how much further every 1% of battery will take you on this phone compared to other phones in its class. Fast charging kills batteries anyways, so I charge slowly most of the time since I'm always around a plug these days. I really wish I had this phone back in 2011 when I lived on a bicycle and was always on the road away from home and/or power. My only other gripe is that I wish there was a software switch to turn off fast charging like Samsung offered. Sometimes I only have a fast-charge enabled charger around, but would prefer a slow charge.

I don't slow charge in the traditional sense, but I use a QC 3.0 charger for the same reason. It maxes out at 3A to the battery, or 0.6C charge rate. It's still plenty fast, but slow enough relative to battery capacity that it doesn't stress the battery much and no need to worry about turning a setting off in the phone.
Im using 25w adapter PD to charge V60, charging speed is too slow, need above 3hours from 10-100.
Checking battery in hidden menu, saw charong current max is 1,7A, usually lower.
Normal adapter give me same speed (like a cheap samsung fast charge adapter).

I am having the exact same issue. Have you found any solutions yet? I am about to either return the device or change the battery and charge port. Although, I am not sure if it will help because it has 10 watt wireless charging and still maxes out at 6 watts on wireless.

iam using Xiaomi 33w adapter with a Baseus cable, dont use Xiaomi cable (with red color inside usb port, this cable hold 5V only) .
This combo charing my V60 fast (about 1h30 -2h). Its acceptable for me.
Now i dont mind about charing speed anymore.
Hey bro i hqve a 36 watt fast charger. I noticed that my phone charges in 1 hour 40 min before. Now it still ahows me 1 hour 40 min but it takes hours to charge..... It is still showing fast charging. It never happened before
