Mi3/Mi4 supports Quick Charge 2.0?!

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

Must be rom related? In miui i can get 1500+ but lcd gone crazy and in stock i got 1000 below. In ivan i can get around 1900+ average without the lcd going crazy

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

Which FAST charger I should order for my new Huawei P9

Hi to all
Just ordered a new EVA-AL00 from eBay last night. I am living in Canada. May I know which charger I should order to take advantage of the quick charging capability of the P9 ?
Is P9 using QC 2.0 or 3.0 ?
Please kindly advise ASAP.

HI
wrong! fast charging is supported by huawei fast charger
but only with this charger i tryed with asus 5v2A/ 9v2A but dont working

anyone who can provide a link to where i can buy one with an eu plug?

I'm considering buying this phone over the S7 (although still undecided) and I still don't get the battery thing (charging or battery life, I get people telling me all sorts of contradictory things that I'm having a hard time to fact check). That 9V/2A charger doesn't come with the phone, right? How much faster is that Huawei charger compared with the 5V that comes with the phone and what is it called since I can't find it on their site or anywhere? Is that the Mate 8 charger?

Yes it's mate 8 charger

Well, no EU plug still available. But it will be later I think. It is not QC 2 or 3, it won't work. Search for "Huawei 9V 2A Charger".
The result should be like this: http://www.ebay.com/itm/Original-9V...hash=item280f7d97a4:m:mNQwKZr7I5KHReS9CA2RwkA
As I metioned, no EU plug yet, so via adapter only.

Edit: 100% at 23h02 ( 54% in 1h00 approximatly) but when i have the time i will try a full charge because the fast charge is more active at the start and midle of charging

With this Aukey charger I got from 5 to 95% in about 90 minutes

It's fine, it will charge as a standard charger at 5V. I would have to brush up my Ohm's law but I don't even get why Huawei's standard charger on the P9 has 2 Amp electric current value. What matters is the voltage going into the battery and you don't need a 2 Amp charger to give you 5 volts, a regular 1amp will be able to do that. The only difference I know is that 5V at 1 amp are 5 watts and 5V at 2 amps are 10 W. But that has only to do with resistance, I think, a battery isn't fed on watts?
I'm really on the fence about this fast charging thing now. I never got it. Qualcomm's has its QC 2.0 tech but a Motorola charger is faster than any other. An S7 Edge with amuch bigger battery charges as fast as an HTC 10 and the Edge has a 2.0 QC and the HTC is 3.0. The G5 is also 3.0 and charges way faster than the HTC, even compensating for the different battery capacity. And I own a G2 which has no fast charging at all and will charge from 0 to 100% in less than 2 hours on a 5V generic charger, which isn't very far off the times I see with 3000mah batteries and Quick Charge 2.0 or 3.0... Why these differences?? No idea... Somehow I think battery chemistry has a lot to do with it (it does in the RC and electronic cigarette world) but I never see anyone addressing that.
^^^^sorry for the rambling, just thinking/writing out loud

Nearly right! A little analogy may help... Think of Voltage (V) as the diameter of the water tap, Ampage (A) as the speed of the water through the tap and Wattage (W) as how quick you want the bath the taps are filling!
So you can see, a small diameter tap but high water speed will still not fill bath very quickly, neither will a big diameter tap and slow water speed...you need both together. So 9V2A should charge quicker than 5V2A (18W compared to 10W).
As I understand it the P9 will accept charging at 9V and 2A (their Fast Charging) giving max 18W input so a 9V2A charger should give the best results (which is what the P8's fast charger is)...and what the qualcomm quick charge 2.0 (and 3.0) spec can provide. Now i'm not saying the P9 is a qualcomm quick charge phone, it's not, but my QC2.0 and 3.0 car chargers certainly charge my phone quicker than the included mains charger! So i suspect that the car chargers are providing 9V2A to the phone.
Whether this means any 9V2A charger would do......I don't know

Quickcharge 3.0?

Does this support QC3? I have two chargers I bought for my HTC, wondering if they'll likely to work currently.

No that's a qualcomm product. This doesn't use a qualcomm CPU. It has a faster form of charging called Huawei Supercharge.

Ah, OK. I best look at other car chargers than

Yeh just seems a good idea to have one that also supports Quick Charge as other family members have Samsung devices with Qualcomm processors.

Anker Powerport Speed 5 is working perfectly in Super Charge on the 2 USB Quick Charge 3 and Super Charge (slower) on the 3 other USB slots

Does it detect as fast charge or slow charge on the Anker powerport?

i'm using a Mi powerbank pro, it supports QC3.0 and also huawei fast charge, not as fast as super charge, but it'll get the job done.

Huawei Mate 20 Lite can support fast charge?

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.
