It appears like Samsung's Adaptive Fast Charge is in fact an equivalent of Quick Charge 1.0 but not Quick Charge 2.0.
Samsung's adapter outputs either 5V or 9V:

Quick Charge 2.0 outputs 5V, 9V and 12V. It is confirmed by this photo of Motorola's Turbo Charger as well as exemplary page of some OEM quick charge 2.0 adapter:

Just a guess but I expect your need a bigger battery, like that in a tablet, to handle charging at 12 volts. As it is, I'm blown away by how fast this phone charges on the adaptive charger. Just wish I could get one for the car.

I couldn't agree more :highfive:
Yep, its a beast at charging, according to PhoneArena it remains the fastest charging phone around, so its Adaptive Fast Charging is doing an incredible job!
My concern would be what it does to battery life..can't help but think the lifespan of the battery will take a hit using fast charging all the time.

You could always buy a car power inverter and use the fast charging adapter with that.

My car has an a/c outlet; the real problem is just finding stock on the adaptive charger. Even then, don't much want a cord running to outlet in back seat. As for using an inverter.. D/C ports are in awkward places to use one in Explorer. Will make due until auto version is available.
Guys does anyone know if the below accessory is real?
Samsung Qualcomm Quick Charge 2.0 USB Car Charger [Part No: ECA-P20CWE]
Not sure if this is real as this is the only website that stocks this 'Samsung branded' charger. A google search shows similar items on Alibaba so I'm guessing this is fake.
Anyway I am going to buy this:

What do you mean you wish you could get one for your car? There are plenty of compatible models available for your car. This one has 1 quick/fast charge port and 3 regular 5v 2.4amp ports.

You are quoting a post from last October. Things have changed.
2.0 works the same?
I am planning a 900 mile hike and need to minimize weight since I will be bringing filming gear. I have purchased a light weight plug strip with Quick Charge 2.0 USB ports. Will this work the same as the Adaptive Fast charger for my Note Edge? Or will I still need to bring the little white USB/AC plug thingy?
Thanks!
Guess I'll find out when the plug strip arrives.

Hey all, haven't been able to find an answer for this. So I'll open a new thread. Now the question. The phone seems to take a long time to charge. Is it possible for me to use my Note 4's quick charger or can anyone recomend a faster charger for this phone? Charging it with Note 4's 2a charger wont damage the battery? Thank you.
I use a 2.1 out and it charges in about an hour and a half
Charging isn't fast and it seems that if the phone gets warm, it draws less power then too - so on a warm day, it can feel like it's taking years.
Would have been nice to have had wireless charging support and/or turbo charging, but alas not.

Doesn't the phone support quick charging? But Huawei haven't bundled the appropriate charger?
Doesn't appear to. I've got a Qualcomm Quick Charge 2.0 adapter and it doesn't seem any faster, nor say fast charging.
There's a quirk, when the battery shows 100% it actually still keep charging for another 30 minutes. All tests showed that it took 3hours+ to fully charge it. So quick charge my ass.
So just to update, I have tried charging it with note 4's fast charger and it charges the phone from 20 to 100% in about an hour and a half. Which imo isn't that bad. With the included charger, it took me around 2 and a half hours... Huawei really should have included a charger with higher amp, 1 is way to low.

It's sadly very common for phones to ship with poor chargers (1A and even lower), but then again - some phones these days come with NO charging adapter, assuming you'll have a ton of them anyway.
I use a 2.1A 5V charger, but I've tried the faster ones (that can output 9V) and it doesn't speed things up, so while it can charge faster with a better PSU, it won't ever charge as quick as many other flagships. Mind you, has the G4 been given full support yet? Likewise, the Z3 is down as supporting Quick Charge 2.0 on Qualcomm's website, but then turns out to be only some variants. Makes me wonder if the Z3+ supports it in every guise.
Not sure what the reasoning is for devices that could support faster charging not actually allowing it, especially if the manufacturer could profit from selling faster chargers separately.

I read an article about Huawei declining fast-charge for "battery-purposes" so it can have a longer life cycle. But i think Huawei made an exception about the Huawei Honor 7.
I had an Samsung before and never had problems with fast-charging whatsoever.
My P8 was full in about 2 hours with an 2.1 A charger, while my Samsung Galaxy Mega 6.3 took 1,5 hours.
the screenshoot took from Huawei P8 & P8 Max Launching Event 2015 said that p8 has quick charge at min 21.30 but they didnt talk about that in the event

Any one Disappointed with the charger they included with the Pure. The non removable cord just sucks and a poor choice in my opinion
I'm more disappointed at the size of the wall wart. They could have made more friendly to other power strip users.

Pretty sure they did that so you couldn't just stick any usb charging cord in their...it'd most likely fry it.

If you plugged in a charging cord that can't handle the increased power it sure could fry the cord. I feel ya though...it would be nice if it were a USB cord.
I'm glad it looks different.... My son knows NOT to plug his HTC M7 into this charger.
I can see if this was someones first Android, the lack of a micro-USB for data would be frustrating, but I have about 5 of these in my desk drawer and throughout my house and office, so it doesn't bother me.
Also having a fixed cord means you don't pulg some 'slow' cable in and not get any benefits. Out my 8-10 micro USB cables, only 2-3 get a decent charge speed.

If a device that does not do Turbo Charging is connected, the charger should automatically adjust and charge it at regular speed. At least, that's what it is supposed to do. The Turbo Charger is supposed to be the single charger for all types.

I think the reason they made the cable fixed is because a lot of cheaper usb cables use very thin wire gauges. Since this charger puts out a lot of current at varying voltages, it's very possible for a thin cable to overheat easier and catch on fire. And my guess is, they didn't want to take any chances
How do we determine if turbo charger is ongoing? I mean are there any indication? Coz when I plug in the TurboCharger that comes with it, sometimes TurboPower Connected shows at the bottom of the screen, sometimes not. Then when I check it on the Status, it says Charging over USB, not Charging over AC? Could be that my unit is defective? perhaps the charger? or the battery?

I've got the same issue going on. My replacement from Amazon will be here Tuesday so I'll have time to mess with both and see if its the charger or what. Currently my turbocharging is hit or miss.

I have this issue sometimes to. So if I need to know if im charging at turbo I use an app from the app store to see if states I'm turbo Charging or not. In the Charging screen it will say "normal or Turbo"

You can use a USB voltage/current indicator device to see it directly. I use one that displays voltage and current simultaneously, it cost about $10 on Amazon.
The Qualcomm QC 2.0 (which Motorola terms "TurboPower) spec is 5, 9, 12, and 20 volts, with up to 2 amps plus at each voltage. The QC 2.0 chargers I've tested including the Motorola charger included with the XT1575, range up to 9V and about 2+ A at 9V, with the higher voltage/amperage when battery is discharged to a lower SoC.. Haven't seen 12V or 20V, I think those only come into play when battery is discharged to nearly zero SoC.
Agree the reason the included charger has cable attached may be to ensure adequate wire gage. Too-thin wire will increase voltage drop across cable thus lengthening charge time in higher power modes. But the design here uses higher voltage to keep current down around the same 2A max current of USB 2.0 chargers, so cable heat will not be a problem with any old USB cable.
I will attest to the benefit of QC 2.0. I thought it was a useless gimmick until I started using it. It does effectively compensate for mediocre battery capacity.
My "Turbo Charging" icon displays properly, but doesn't charge very quickly if connected to a cheap extension cord.
Plugged into the wall, the charging Stull doesn't impress me that much

It's defective. Call moto they will replace it for free. Just have to send copy of purchase receipt. Had the same issue.
The charge rate depends on how discharged the battery is when connected to charge.
More discharged (lower SoC, State of Charge) will drive a higher charge rate.
As to the difference between this Motorola TurboPower (aka Qualcomm Quick Charge 2.0), vs. other phones:
I've measured up to 1.4 amps at 5V nominal on other phones, that is about 9 watts charging power. That is max charge rate, with a very discharged battery. As the battery charges up closer to fully charged, the charge rate (power) is reduced. Total charging time from fully discharged to fully charged would be about 4-5 hours, give or take, for a typical cellphone battery.
For comparison, the QC 2.0 measurements I made with the MXPE: Up to 2.2 amps at 9V nominal with a phone battery discharged to about 40-50%. That works out to about 20 watts charging power. As with other Li-Ion battery charging systems, this also declines as the battery approaches fully charged. Total time to charge, from fully discharged to fully charged will be about 2-3 hours, give or take.
So the marketing claims about QC 2.0 are about right: A 75% improvement over conventional charging systems.
The biggest gains come when charging batteries discharged to lower SoC. If you are comparing charge rate/time of batteries discharged to only, say, 70-80%, you will not see as much of a difference with QC 2.0.
I'm not a QC 2.0 marketing shill, mind you. I pretty much ignored it, before buying the phone. But for this phone, QC 2.0 actually does a good job to compensate for the mediocre battery. I can run the battery down to 40-50%, put it on QC 2.0 charger in my car for my 30 minute commute, and it is charged to around 80+% when I arrive at my destination. There are a lot of QC 2.0 certified aftermarket chargers out there too, Qualcomm did a lot of work on the front end as part of bringing it to market. (Just make sure any AC charger is UL listed or equivalent, if you care about safety.
Caveats on cables: The cable does make a difference at higher charge rates. Thinner gage wire will impose a greater voltage drop at higher current, this will reduce power and thus increase charge time.
Typical USB cables are AWG 26-28. You can buy 20, 22, and 24 AWG USB cables. Some cables advertise heavier (22-24) gage wire for the power leads with standard (26-28) gage wire for the data leads. The aftermarket QC 2.0 AC chargers I bought listed their included cables as 20 gage.
Get the heavier gage if you want full QC 2.0 charging.

Just to check did you use S6 original charger ? And does it charge same with the turbo power charger provided by moto?

Method:
First I used my phone until the battery was below 15% in order to get a better picture of what the charging would look like over almost a full battery cycle. I did not start at the same battery percentage for each test because I did not find any benefit to doing so. I original did this for uniformity, but it did not make a difference after trying it using the more accurate equipment.
I then cleared my history in the Battery Monitor Pro Widget (BMW Pro) recording app which was used to log the battery [mV], battery temperature [F], time, and battery percentage changes. Once this was done I plugged in my USB Power Monitor, turned airplane mode on, removed the case, and let the phone charge. I started logging the data via my power monitor once the phone showed it was charging. From this point onward I let the phone charge without interrupting it until it reached 100%, then I let it charge for another 10-60 minutes to see if it was still drawing power from each charger. Once all of this was done, I exported my data collected from BMW Pro, emailed it to myself, and pasted it along with the USB Power Monitor data into an Excel spreadsheet. All of the data was then delimited to separate the clusters of data due to the way they were recorded, and subsequently graphed. The USB Power Monitor recorded data points every 0.36 seconds, while the BMW Pro took recordings every 5 seconds because I was having issues with the “real-time” recording option in the app working correctly.
All of the data was then graphed into the nice figures you will see below; each color reflects the same variable across all of the graphs to make reading them easier. I included a legend at the top of each set of graphs which should also help make it easier to read the data.
The most interesting part of this test is how cool the S7 Edge stays while charging, and the very marginal difference in overall charging time between QC 2.0/1.0. A 15-minute gap is marginal at best given the ‘big improvements’ Qualcomm claimed when launching the newer standards.
When conducting the wireless charging tests I think there is some error in the Samsung Fast Wireless charging data, so I plan on redoing it at some point. I already redid the Choetech one because it has a similar strangely long, but now it seems more in line with what I initially found before using the newer testing equipment.
I wanted to also quickly point out that both my HTC 10 and S7 Edge keep pulling current even after the phones show they are 100% charged. I’m not talking about a tiny amount; they both pulled ~1-5W+ after hitting 100% battery which is A LOT considering they are reporting to be fully charged. I verified this using 3 multimeters just to be sure. It appears as if Qualcomm, or the OEM’s are falsely reporting when the phone is actually charged, or there’s some other shady things going on here.
Another thing I wanted to mention is how the S7 Edge is so consistent in the way it charges the battery. It could be due to the lower rates Samsung uses (9V/1.67A max which is 15.03W) vs the HTC 10’s up to 18W that I’ve seen it pull. Just take a look at how the S7 Edge charges using QC 2.0 compared to the HTC 10 with lower temperatures, similar times, and a much more consistent overall charging curve.
If you look at the Tronsmart & Choetech QC2.0 tests, then you might notice the large difference between the two. The Tronsmart charger has a harder time holding onto the proper voltages, therefore it bounces around more from ~8.92V-9.03V (a 0.11V change) while the Choetech one ranges from 9.077V-9.092 which is a significantly smaller 0.015V range. The power control chip is responsible for controlling these voltages, and clearly the Choetech one has a better chip in it. This is especially important for external battery packs where efficiency really matters due to the limited amount of power they can store.

maybe you could also record the heat at the hottest spot of the phone during charging? I think qc3 has the same charge rate but its able to change voltage to reduce creating waste heat compared to qc2.0.
my main concern with the s7 is the battery life, i know it won't last me a full 18hr day so i really need a portable fast qc2 charger that is pocketable, so maybe 5000mah, but have not seen such a small qc charger tho

I don't have a thermal camera, or way to do that otherwise I gladly would. I can recommend a small 6000mah external battery pack if you want; Ill do a quick write up too (if you need one). The Samsung charger stayed at 9V the whole time per my multimeter's reading it just dropped go .5A near the end.

Thank you, I will add in a standard wireless charger test (since my free Samsung one is enroute), and I can also get their fast charger too. I believe Samsung's fast wireless charger is only 7W so it would be slower than the Choetech one but it never hurts to see how fast it is.

@Pilz yes pls let me know of a qc2.0 small portable charger I think a quick 30mins charge to add 50% battery life mid day will be the best ease-of-use solution for me.
with the heat measurement, I'll be happy with your commercial grade temperature sensor that the great designer created for you, your fingers or better yet, the inside of your wrist.
preferably touching the same area on the phone every time and grading something like 1-5 hot/comfort levels maybe? just suggesting, no pressure

I'll look into some methods to measure the heat easily while they're charging. I'm conducting the standard wireless charger test using my free Samsung wireless charger right now QC 2.0 chargers the fastest when you start at a very low battery percentage, so ideally you can achieve the results posted, but ambient temperature, starting % etc contribute to whether or not that's attainable. It's still a good estimate for 30 minutes of charging +/- 5% for other factors. The phone also chargers slower when the screen is in. The rate would go from 9V/1.67A to 9V/1.10A with the screen on. It was very consistent when I turned the screen on and off during the test.

i actually won't care about heat issues while charging this time round, it'll be like my moto defy, i just run it under cold water after a fast hot charge, wont be using the s7 for many years so not worried about moisture build up.
i have ordered a magnet micro usb cable that says its rated for 2.4A charging so hopefully it'll allow easy qc2.0 charging, no need to plug in, it magnetically snaps on and off.
i think the best charge setup would be a 30mins quick charge (magnet) on the office desk than a 60mins wireless qi charge, carried in your pocket type situation.

Did you by chance order the Znaps? I backed them ages ago for both the Type-C and micro USB connectors. If I'm lucky I might eventually maybe sometime before I die receive them. I don't expect much from a kickstarter campaign that's been delayed this much. I'm finishing up the standard Qi/PMA charging test. It shouldn't matter the standard it's using but if it's important the Samsung wireless charger is actually PMA.

no, its from aliexpress, $10 or so, ive seen cheaper so I would say the poor Kickstarters had their designs stolen and made cheaper... im not sure, i just buy what's available and easy. just search magnet usb cable, you'll find heaps, the more exy ones claim 2.4A current rating.

Let me know how it works, I rarely use cables to charge my phone becusse I hate micro USB ports plus I'm used to the type C on Nexus.

Have you tried charging with 18w charger(not wireless) rather than the samsung one?

Yes it doesn't matter becuase the phone is only rated for 15.03W so it can't use more than that no matter the charging method. See screenshot below:

@Pilz yeah sure, it should arrive in a couple of weeks. i hate plugging in as well, even with the usb type c, its reversible but finding the port isn't always easy, they should have made the port surface like a cone or funnel so your guided into the port more easily.
the use of the magnet is awesome, Sony's external side charging pins have been around for ages, its really the charging current and quality of the copper that im worried about.

I just wish they had Type-C because its so much better especially after using it for a while now.

I never knew that plugging in a micro USB cable was so difficult. It could be one of those things that once you try a better alternative (type c maybe?) makes you ask how you lived without it, but I don't see what the fuss is about just yet.
I've used wireless chargers for years (way back in the NExus 5 days even) including in the car. Any word on fast wireless charging and heat? I'm worried about it pumping a ton of heat on to the back of the phone especially for extended periods such as overnight.

Micro USB is just more of a hassle becusse usually you need to angle it while inserting it into the phone. Type-C is nice becuase there no worrying about how I need to orient a cable when I'm half awake plugging my phone in. It's hard to understand why its nice until you use it everyday.
I haven't been able to measure the heat yet, but the phone is cooler using the 10W wireless fast charger than it is using QC 2.0. The phone isn't hot to the touch but it is warm using the fast wireless charger. I'll try to download a battery monitoring app that measures battery temp while it's charging. This method won't be as accurate as physically measuring it, but it should still give a good indication of the temperature.
Edit: I tested the temperature using GSAM battery montior via the fast wireless charger fro ~6% charge (28-34%) and the temperature rose 6 [F], the I let the phone cool and tested QC 2.0. The phone was charger for 6% to keep things cosnistent with a temperature change of 5[F]. I would need to find a way to more accurately measure these values because that quick test doesn't really mean anything at this point.

It's just a QC 2.0 charger from what I can tell. I have a battery pack that will charge using QC 2.0 so I can test it using my multimeter

So, I have finally learned what in my charger makes it fast. It uses the 5V and not the 9V, not sure why there's a 9V if phones use a 5V but I learned that the more amps the faster the charging. Like I currently have a ZTE 1.5A charger and a friend has a 4A dash charger for their OP3. Mine takes over an hour and their's takes a hour at most they claim. So if the V20 supports 3.0 charging, what's the most amps I can use in a charger to get the fastest charging possible? Would it be unsafe if I went to some extreme amount, like would it make my phone over charge and blow up or something?
The total power charged (watts) = voltage x amperage. So its a function of both volts and amps. For the fastest charging get a charger that supports qc3. This is standard that includes both how fast to charge and a signature that the phone and charger support qc3 to actually use the faster charging.
If you get a charger that doesn't support quick charge but some other standard the phone and charger will see that they don't support that other charging standard and charge at a safe slow rate.
The V20 does not support QuickCharge 3.0, that needs to be clear from the start because it causes a lot of confusion. The Snapdragon 820 does have support for the QC 3.0 standard, but LG chose for some reason NOT to support it. What the V20 does support is USB-PD aka Power Delivery which is similar to QC 3.0 in how it operates but it is NOT QC 3.0 (but the V20 does support QC 2.0 without issues with the stock charger).
USB-PD works like QC 3.0 in the sense that it does the charging in a different way that keeps the cells cooler during the charging process and doesn't cause the heat buildup that QC 2.0 causes. The factory LG V20 charger supports QC 2.0 and if you go into the hidden menu (*#546368*<3-digit model number>#, might not work on every variant) and then SVC Menu - Battery Test - Battery Info - select the Enable Log button - check the box for Battery Log Save On/Off and it will then show the relevant info. Once you see the information display, plug in whatever charger you wish and then wait and see what it shows for High Voltage parameter.
If it's QuickCharge it will show the version being used - the stock V20 charger shows me QC2 so that's QuickCharge 2.0. I have a Samsung QC 3.0 compatible charger and when that's attached it shows USB-DCP which from what I understand is Samsung's modified variant of USB-PD but that could be wrong. I did some quick research and found this so it could be limiting the charging to 1.5A which is perfectly fine with me):
Dedicated charging port (DCP) BC1.1 describes power sources like wall warts and auto adapters that do not enumerate so that charging can occur with no digital communication at all. DCPs can supply up to 1.5A and are identified by a short between D+ to D-. This allows the creation of DCP "wall warts" that feature a USB mini or micro receptacle instead of a permanently attached wire with a barrel or customized connector. Such adapters allow any USB cable (with the correct plugs) to be used for charging.

That was taken from this page:
https://www.maximintegrated.com/en/app-notes/index.mvp/id/4803
My V20, using the stock Samsung 2A charger that I always use (because I don't like to quick charge my batteries, I don't trust it in any form and I still think it's damaging the cells but that's my own personal opinion on quick charging overall), can go from 15% to 85% (I use AccuBattery set to 85% and it alerts me when it hits that point so I can unplug, this increases the overall lifespan of the cell I'm using as measured in years not per-charge) in about 55 minutes to 1 hour depending on whether I'm still using the device or letting it charge screen off. That's using a plain old vanilla 2 amp capable charger and when I check the charging current sometimes it'll actually show 2.2 amps (2200+ miliamps) so I'm perfectly happy with that situation.
I've read reports from owners of Pixel USB chargers and when they use them with their V20 smartphones and look at the battery info in the hidden menu it will show USB-PD so I might have to get one of those sometime and see how it goes.
Suffice to say, 55 minutes for a 15% to 85% charge for me is fast enough and the battery still stays pretty cool overall. USB-PD is probably the best tech we'll be able to make use of with the V20. I've read that the V30 does fully support QC 3.0 without issues and the the stock V30 charger is QC 3.0 compliant. The new V40 is QC 4.0 ready but I don't know at this moment whether or not the actual stock charger handles it but again, the QC 4.0 support is handled by the SoC and it remains to be seen if LG allows it or forces it to QC 3.0/USB-PD operation. Guess I need to do some research into that aspect of the V40 too.

The V20 can support QC 3 with a custom kernel, for example with mk2000 oreo 1.1 beta with a qc3 3 charger it indicates HVDCP_3 (HVDCP is one of the important parts of quick charge)
I've been using exclusively pd or qc3 chargers with my v20 and both properly work, verified with a usb power meter. Qc3 does the little 200mv adjustments as expected. Although to be fair i do run mk2000

Have always doubted whether it was QC 2 or 3 but the log shows QC2.0TA in the service menu. Voltages measured by an inline meter are closer to 9V and around 1.3A (only with screen off) which suggests QC2. Power in shoots up to 15W initially and then drops to 13W and then 11 something W.
QC3 would be closer to 7V something with a higher amp input.. That's what the QC3 power bank used to charge the V20 accepts when charging itself.
This is stock btw, not rooted nor using any roms.

I found this interesting and hooked up my 100W laptop usb c charger to the phone and then use a usbc inline meter and found it did quick charge. At the same rate as Qc2. The meter read 8.91V @1.5A . This is surprising as i'd have thought usbc operates at 5V and a higher amperage.
When i looked at battery test screen from the service menu, the item for High voltage TA status reads as OFF. Yet my plugable usb c inline meter records around 13.5W going in with screen off. The voltage was 8.91V 1.5A. That's not USB-PD afaik, which should have said 5 V and a higher current draw. My laptop charger does not do Qualcom quick charge at all, So i'm not sure what is going on here.
I've been wary of using my laptop charger to charge the phone as i'd read an early report that some people had a bootloop problem and it was caused by USB PD chargers.
The factory LG V20 charger supports QC 2.0 and if you go into the hidden menu (*#546368#*<3-digit model number>#, might not work on every variant) and then SVC Menu - Battery Test - Battery Info - select the Enable Log button - check the box for Battery Log Save On/Off and it will then show the relevant info.

Interesting, when i hook up a ravpower power bank that is also QC3 comparible i still see QC2. It charges no faster than the stock charger LG includes in the box

Not in my case with a laptop charger, it just reads as OFF.. Do you remember where you read this maybe a link.
However when i use the laptop charger to usb C PD charge my power bank, the meter reads 4.89V 2.77A. That is a usb c PD charge. These are not the figures i get when using the laptop charger with the V20 as indicated above.

I have mixed views about USB-PD and its suitability for phones. Laptops have larger cooling areas and so USB PD is fine with them. My laptop has a 100W charger and its charging as i type this and i don't find the laptop gets warm at all. The history with the 6P & First pixel showed people with battery problems and having to replace the battery shortly after a year. Particularly with the 6P. Not heard any problems with the second gen pixel as yet. Maybe its still too early. But even with qualcom quick charge and i use it all the time there should not be any problems with battery after a mere year.
Having said all that in the last post I made, a friend gave me a Samsung EP-TA20JBE charger last night, go figure. It's the first Samsung "fast charger" that I've had and I decided to plug it into my V20 and see what it showed. I know that if you use the Pixel chargers the battery info in the service menu will show USB_PD meaning it's communicating and charging using the Power Delivery standard. My regular Samsung 2A charger - plain old vanilla non-QC compatible straight 2A charger - shows USB_DCP when charging my V20 so that's a known thing; there is no QC support, no PD support, nothing but just pure current provided as requested.
Here's the funny thing:
The Samsung EP-TA20JBE apparently is a QC 3.0 compatible charger, but since it's made by Samsung what I see under the battery info is USB_HVDCP which I've never seen before. So I did research into the USB_HVDCP meaning and of course the HV means High Voltage.
What I discovered is that if you're using a true Qualcomm compliant QuickCharge 3.0 device with a true Qualcomm compliant QuickCharge 3.0 charger, your device should report it's getting QC3.0 under the battery info but that's where the fun begins because non-compliant hardware will just show "USB_HVDCP. Of course, because this is not an LG charger and the sense and communication stuff is not from them, it's falling back to Samsung's version of QC3.0 protocols - but what I discovered is that in such instances it's actually Qualcomm QuickCharge 3.0 in effect, it's just that on non-compliant chargers Qualcomm detects the charging protocol as USB_HVDCP.
So, I ran my V20 down to about 15% using a battery app that forces the device to use nearly 100% of the CPU, that took the better part of 45 minutes or so, and when the phone beeped to alert me it needed charging I stopped the battery rundown app, let the phone sit for about 15 minutes idle so it would cool down, then I plugged in the Samsung USB charger I picked up last night (using my Monoprice 26 gauge USB-C charging cable).
Normally if I charge the device using that Samsung vanilla 2A charger from 15% it will cause my V20 to get warm on the backside because it's pulling the full 2A from the charger and of course it'll get warm. It also takes roughly 55 minutes to about 1 hour solid to go from 15% to 85%, and the phone will stay warm till about 65% when the current pull changes to something lower, maybe 1.5A, and it continues to decline as the actual charge increases and of course the V20 cools down to various degrees (pun intended) as the current pull decreases.
But here's what I noticed using this Samsung USB charger:
I watched the charging indicator (screen off, I use AccuBattery which shows me the current battery percentage on the V20's second screen) and it was literally going up 1% every 35-40 seconds which I had never seen before, all the way to 85%. My V20 remained basically cool to the touch from the moment I plugged in that charger to the time AccuBattery alerted me about the 85% cap - that's what I have it set for to ensure I get a longer lifespan (measured in years) from the OEM LG cell I bought back in August, manufactured in Nov 2017 by the date on the battery.
So, I'm not sure what this all means but based on what I read about Qualcomm and how their chargers ID themselves, if you see USB_HVDCP that is QuickCharge 3.0 under the battery info in the service menu - it's not Power Delivery because the Samsung charger doesn't apparently support that protocol (but I'm not 100% sure on that one).
It's actually honest-to-goodness QuickCharge 3.0, according to the info I read yesterday afternoon, so while I'm still not 100% sure on the protocols or the various naming conventions like USB_PD, USB_DCP, USB_HVDCP, etc (I mean I know what they stand for, sure) and how the V20 identifies the charging protocols and usage, what I can for certain is that for the first time since I've owned my V20, I can charge it with this Samsung USB charger and never feel it get warm at all so for me that's a huge positive. Li-Ion batteries HATE heat buildup, that'll kill their effective lifespan (again measured in years) more than most anything else.
All the vanilla 2A or 1.8A chargers I have cause the phone to heat up during the charging process. I have a Motorola "TURBO" 25 watt QuickCharge 2.0 compatible microUSB charger that I used for testing purposes with a microUSB-to-USB-C adapter and under battery info that identifies as USB_DCP so that's QuickCharge 2.0 (which that particular charger is designed for) and the battery heats up when I use it. This new Samsung charger I just got last night, charges just as fast if not faster and there is NO heat buildup whatsoever that I could detect so, yep, QuickCharge 3.0 even if it's not identifying as QC3.0 under the battery info.
I suppose what I said earlier is now considered moot: the V20 DOES support QuickCharge 3.0, just not with the stock LG charger because it's not a QC 3.0 charger to begin with.
So, yeah, I guess I'll be using this Samsung charger from now on.

Plain USB_HVDCP is quickcharge 2.0, when its 3 it shows as USB_HVDCP_3 (if you use a custom kernel like mk2000 and a qc3 charger its possible)
What made me think the V20 uses QC3 is the inline meter i used with it said so. This btw is from the stock charger too. But the voltages do not convince me
The voltage between qc2 and 3 are pretty much the same, but 3 has more levels in between the max and min voltage so less energy is wasted.
They're not the same. I remember a post from the HTC 10 forum and that phone comes with a QC3 certified charger and the volts were in the 7 range with higher amps. Which btw is the same as when my ravpower power bank charges with a QC3 compliant but not certified charger
So we still don't have anything absolutely concrete, great.
But as I said, with a QC 2.0 charger (the Motorola TURBO one) my V20 gets quite warm from 15% to 85%.
With this Samsung QC 3.0 charger, it doesn't get noticeably warm to any significant amount from 15% to 85% AND it gets charged faster.
So I have no idea and really just figured "OK, whatever, it charges faster and cooler, I'll use it..." and that's that.
