As the question above if fast charging is better why Samsung let us make a choice? What is the difference?
Sent from my SM-N910C using Tapatalk
Probably is not better, its faster. I would imagine it will shorten battery life because of faster battery degradation due to exposure to higher temperature more often than "normal" charging.

so if i unchecked the option, but use the provided charger, it will still charge fast?

Still charges relatively fast using the bundled charger without Fast Charge checked. I leave it unchecked as I'm never in a hurry when it's time to charge my phone.
and if i dont want to charge it fast, i have to use other charger?

You don't have to use a different charger. Just use the bundled charger but uncheck Fast Charging, then it will charge normally.
but it still charges fast with the fast charging box unchecked... in ~1h its full.
or is it just me?

Yes, as I have mentioned earlier, it still charges relatively fast without Fast Charging.... 0% to 100% for me it's under 2hrs, never really timed it.
Charger provides 2 A at "normal" charging, battery capacity is about 3 Ah.
So in theory, 1,5 hours are suffient to charge the device in "normal" mode.
In practice, it should be about 2 hours for a full charge.
Fast charging poses a slightly higher burden on the battery, that's why Samsung gives us the choice to select whether we like that or not.
(Would be just nice if Samsung gave as the choice of selecting if we wish to have Knox or Region Lock, too.)
But as we've got a changeable battery, I don't care too much.
Anyone disabled fast charging? Tried it and it is super slow. When slow charging + using the phone, the battery % will drop instead. Tried fast charging, it's an hour or so from 20%. Problem lies in the slow charging.
P/S: I am using the Ori Charger from box and also from my previous S6E. Both are the same model charger.

Right after your post, the only thing I haven't changed was the cable. My intial try was:
Try 1: Old S6E Fast Charger + S6E Cable
Try 2: New S7E Fast Charger + S6E Cable
Try 3: Old S6E Fast Charger + S7E Cable
It states Cable Charging when I changed to S7E cable and thank god it matches your description, approximately 1 hour +. I wonder the S6E Cable starts breaking down since previously it's always on Fast Charging, but when I turned on Fast Charging, there's no issue!
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)

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 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.

When you or anyone elses plugs your V30 in at 5-10% battery. Then how long does it say until full?

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.

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).

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
