Alright, can anyone confirm this for me? Wait, lemme start at the beginning...
So I was reading this Android Police article, hoping to get some quoting material for those times when a member thinks USB Fast Charge is the same as Qualcomm Quick Charge 2.0...
http://www.androidpolice.com/2015/06/12/quick-rapid-turbo-and-fast-charging-explained-what-you-need-to-know-about-charging-your-smartphone/
Y'know, all those times people ask a kernel dev "Why isn't Fast Charge speeding up my charging?" so I could swoop in and crush their dreams with "Fast charge means only more current draw when USB charging via PC. You're thinking Qualcomm Quick Charge 2.0, which needs hardware support, so ain't gonna happen."
But turns out, the Mi3/Mi4 DOES have the supported hardware (for Quick Charge 2.0 mind you, not v1.0 like in the Nexus 5)
https://www.qualcomm.com/documents/quick-charge-device-list
(Official document from Qualcomm listing the Xiaomi devices amongst the handful of QC 2.0 devices)
So can someone tell me if this needs kernel support? Or can I just buy a Quick Charger off Amazon and enjoy the benefits?
Or if this is at all LEGIT?

In fact I own an Mi4 which comes with a 2A charger that is normally supporting quick charge 2.0.
With MIUI it's charging 1.8A (of course 1.8A is around 2A minus phone consumption)
On all custom rom it's just charging max 1.3A with about same consumption, or even less.
So Mi4 support quick charge 2.0 with MIUI but not with any custom rom or kernel.
Anything regarding Mi3 ??

In the attachment 1 that is the stock charger of mi3 , in the attachment 2 that is the current of quick charge without the build.prop line. And in the last attachment that is that current with the buil.prop line.
In conclusion, without the build.prop line the lcd becomes super sensitive but higher current, with the build.prop line the lcd is fine but lower current than before

I don't think a 2A charger is an actual Quick Charger. (Obv it charges quicker compared to 1A ones )
Apparently for Quick Charge 2.0 technology, your Wattage/Power input should be around 18W (wattage is found by multiplying the voltage written on charger, usually 5V with current you're getting in ampere). Quick Charge 1.0 supported upto 10W which we're gettng with the 2A chargers, but I think we need an actual Qualcomm certified Quick Charger (which allow currents of upto 3A apparently) to see QC 2.0 at work.

Yes, this guy is right. 2A charger with 5V output is not a quick charger this guy talking about (Qualcomm Quick Charger 2.0). 12V charger output is.
Mi4 charger comes with 3 voltages 5V-2A, 9V-1.2A, 12V-1A...but maximum we get is 12*1=12W
Charging on xc kernel (cm ROM)
MI3 is not support any quickcharge. Even you use 2.0A charger, will give you same about 1.2A
What i know is i had Mi3 in past now i have Mi4 and mi4 comes with a Qualcomm Quick charger 12V-1A. It charges way too fast than Mi3 charger.
I use Mi3 Charger 5V-2A on Mi4 it took 2-3 Hours to get fully charged whereas Mi4 Charger takes 1-2 Hours to get fully charged.
It heats up a lot Charger + Mi4 Both
MI3W support QC 2.0, but needed QC 2.0 charger, for example Xiaomi Quick Charger 2.0 aka MDY-3-EB I`m found it here
Original charger hits 1700mA while Quick Charger 3.0 hits 2300mA. Screenshots below. I'd like to know if anyone else has done a similar test so we can compare results. I bought a (supposedly) Quick Charger 3.0. The results are obviously better but I'm not sure if its supposed to be higher or not.
SD660 can even do Quick Charge 4, but for Mi A2 officially only in india.

Global version might need a patch.
This this means that we can use Quick Charger 3.0 or 4.0 without harming phone's battery?

Exactly! i really don't know how that works.. Does that mean that the original charger is somehow a quick charger?
Empirical evidence suggests that Oreo seems to show "charging rapidly" anytime amperage is above 1 amp or so, it has nothing to do with using a quick charger or the original brick supporting quick charge.

No guys. I found:
0 - 999 mA = charging slowly
1000 - 1499 mA = charging
>> 1500 = Charging rapidly
Not sure if MiA2 use the same parameter.
Nice, I was gonna say 1500 cause that was kind of what I remembered but wasn't totally sure. 1.5A is typically rapid enough to charge with relative speed even while the device is in use which is probably why that was picked. I agree that they should probably provide a reading above 2A to signify quick charging as "charging rapidly" is definitely confusing.

Hi,I was curious if my Mate 20 Lite can support fast charge,I used my friend's Huawei P20 Pro charger brick and when I'm on lockscreen the phone says just "charging",like he doesn't recognize it..and when I charge with his original charger that comes in the box it says "fast charging" but on the charging brick it's written "quick charge" and the charging speed it's clearly slower than my friend's P20 Pro.I didn't test the speed of charging on my.pgone with his charger,I just plug it in to see if it say something different , I'm a Little afraid to let it charge with his fast charge brick
Hey, the AC Charger of P20 Pro supports Supercharge, your Mate 20 lite only supports Quickcharge. Supercharge ist much faster, the AC Charger of P20 Pro doesn't support Quickcharge.
Only the Huawei Car Charger supports both

No, the Mate 20 Lite does not support Quick Charge. The charger has written "Quick charger" on it but don't mistake it for QCs Quick Charge technology.
The charging speed is not as fast as the P20 Pro, but it's faster than most phones and is a form of quick charge.

Huawei Mate 20 Lite comes with Kirin 710 (not Qualcomm Snapdragon) so, obviously it will never be compatible with *QUALCOMM QUICK CHARGE*.
It has a quick charge from 5V-2A (up to 9V-2A) and it includes in the box the *HUAWEI QUICK CHARGE* charger that works with KIRIN chipsets.
The battery goes up fast considering that it has 3750 mAh.

My Mate 20 lite seems to be working with qualcomms QC 3.0 since I updated to android pie and emui 9.0 and 9.1 on a standard charger I get a max of 1800ma using a high amperage cable and power adapter, charging on the included Huawei charger it goes to 3200ma. After I updated I was lazy one day and used the QC3.0 charger that didn't fast charge before, it jumped to 3300ma. I tested it on my USB fan which has a pass through USB (I use it for emergencies as it prevents the phone from thermally throttling the charging), when the charger switches to Quick charge it ramps the fan up as it's getting a higher voltage so it's definitely stepping up the USB voltage. I can't believe it's working tbh as I thought it would never accept a QC3.0 charger.
Do Power Delivery (PD)-only chargers work with the Mi 9T Pro, and if so, at what speeds and which PD version does it support?
Can't really find any tests on this online, I'm surprised it's not standard to be honest -- using one single PD charger for everything is fast becoming the norm.

Yes. Qualcomm QC4+ adheres to PD standards, it's the first time they've done so. Xiaomi haven't used any proprietary charging, they've relied on QC4+ baked on the SD855. You'll get up to 27W charging, depending on the charger and battery level. I find I'm only getting 27W when the battery is very low, normally it's 24W until it's nearing full, but that might be how my charger chooses to deliver the juice.
Not sure what PD version it's using, but I'm sure a Google/Wiki search on Qualcomm QC4+ will provide an answer somewhere.
Edit: a quick look on wiki says that it's PD 3.0

I went for a bit of a gamble on AliExpress and got this one.
https://s.click.aliexpress.com/e/tGXqRBeY
It was a brand I hadn't heard of but had good reviews and was cheaper than the known brands. So far I'm happy with it, does exactly what it says on the tin.
For the price there's nothing much to complain about, you start adding on all the nice to have extras and suddenly the phone would be half as much again.

And you got 24-27w through the USB-C PD port? I guess that must be, since QC3 max is 18 watt right. Grand, thanks for the info!
Not so sure regarding the price, although it's a bit difficult to weight the pros and cons sometimes. Take the Black Shark 2, which is great, aside from the absence of NFC, and no bootloader unlocking, but it's around the same price. Putting a color led in there and HDMI out, that would've made the phone pretty much unbeatable, even if it cost 50 euro or so more. It's definitely making me hesitant to purchase, because what if a 9T Pro equivalent comes out with those two things extra for 50-60 euro more? I would be gutted

Yes, the QC3 port only delivers 18W max.
I'm resuming this thread because I'm really confused on how get 27w charge on my Mi 9T Pro.
I'm using a UGreen USB-C cable that supports 60W Power Delivery charge with an Aukey 27W power adapter (ADEQ-ES-PA-Y8-B) with PD 3.0. The maximum current I get (verified using Ampere app) is about 3.150mAh which is the same I get using three different Quick Charge 3.0 power adapters, the only difference is when I use the QC3.0 adapters the phone shows "Quick Charge" text on lock screen + double flash symbols on the battery icon and when I use the PD charger I have no text in lock screen but only the double flash symbols on the battery icon.
Does anyone know if the "Turbo charge" is achievable only using the original Xiaomi 27W Charger?

It's no good looking at only amps. You need to know what voltage is being delivered too.
Watts = volts x amps
I have 2 PD chargers and both charge the phone at the full 27W, when the battery is empty.
I have a 30W PD wall charger which delivers 27W as 12V at 2.25A, but my 30W PD car charger delivers 27W as 9V at 3A

You can get apps which show volts and amps when charging. Search for Ampere in the play store, written by an xda member, I believe.
I'm using Havoc ROM, which shows these on the lock screen when the phone is charging.
However I've seen people say that these may not be accurate and suggest only USB meters give true figures. I've never tried a USB meter, so couldn't say if the figures I see are accurate or not.
I have two QC 3.0 chargers, a Xiaomi powerbank and a Ugreen Charging hub. Both in theory only support QC 3.0, but when I plug the phone in, they both fast charge it with 3Amps. How is this possible? Won't it damage the battery? I have an exynos model and it only supprorts PD. I couldn't find any information about QC 3.0 being PD compatible, so I really don't know what's going on and if it's healthy.

Yes I know about this, but the phone doesn't support QC 3.0, so what I wanna know is how can it still fast charge it?
Why not ? U have 998U or U1 ?
most chargers nowadays support most charging protocols. most likely your chargers are QC and PD compliant so it can give enough juice for fast and super fast charging on your phone. have a similar-spec'd GaN charger too which i also use for my s21u (exynos). should be safe to use
S21U only suports PD3 fast charging thats is QC4 or QC4+
How fast is your ultra loading? 0-100%?
