Post your charging time (5v2A, QC3, QC4)

I ordered an A2 and a QC 3 wall charger, I'm considering also a car charger, but seems not that needed.
Please tellme... About your Chargint times (Half/Full) on basic wall 5V2A Chager, and QuickCharge 3.0/4.0 chargers, also on car chargers as well
Also, Does anyone tried an iPad charger?

On QC 2.0/3.0 ? form 10% to 100% - around 1h 10m ( not sure abot QC version but was fast charging icon )

I was measuring charging time with stock charger, here are my results:
Greetings everyone,
I have charged my phone with stock charger that came with it, by the way I have global version. 5V=2A)
After a 30 minutes my phone was at 54% i was surprised with percentage!
After an hour I had 92% of battery charged.
Battery fully charged at 1:13.
I want to ask, how fast would battery charge if I use QC v4.0?
Thank you in advance,
DarkoMiA2, :fingers-crossed: Bosnia

Got mine today. I don't have any qc. But have mi power bank which have qc 3.0 capability. I am using but phone doesn't show any quick charge indicator. Is it normal?

I can't find the link to buy a QC 4 charger(I'm from India). I can't find anyone who has actually used snd tested the device with QC 4 either.

As of now there are no QC 4.0 charger in market... It'll take couple of months before they get on shelves for sales.. Till then use QC 3.0 or stock charger.
PS, or you can buy mi 3i power bank, it has QC 3.0 capabilites and when QC 4.0 chargers hit the market you can buy one of those too..so then you will have a power bank and a QC 4.0 charger...

BTW, Do you have any idea about the charging % that we can expect out of qc 4.0 in future?

About qc 4.0 improvement, no idea as there is no charger as of now even in international market..
Edit : quick tip, never but cheap 3.0 chargers found on Amazon (quantum zero, geekzone.. etc)

USB-C PD vs Adaptive Fast Charge?

Does anyone happen to know which one charges these phones faster? If I'm not mistaken, Adaptive Fast Charge is basically QC 2.0 right? So wouldn't USB-C PD be faster?
My phone hasn't been shipped yet, otherwise I would test it out myself.

The phone only supports Samsung's Adaptive fast charging, so using a USB-C PD charger won't make a difference.

It also supports Qualcomm Quick Charge 3.0 as fast charging, just like the S8 and S9s.

That's a QC 3.0 only powerbank according to it's specs.
Take your own conclusions from that...
It charges as fast as the original wall adapter

S10 devices only support 2.0. your previous post said it supports 3.0. it does not.
Any charger will charge the phone, but not faster than the specs allow. I can have a 25w charger but my S10 will not take the 25w capacity

Connect a QC 3.0 charger, see the charging speed, come to this thread again.

go check out the 2000$ Fold, it listed "compatible with qc 2.0".
2000$ phone supports qc 2.0
s10 support qc 3.0 HAHAHAHA
hope you get what i saying ..

Why would I go through all that just to prove what we both already know. You even said it yourself that it charges as fast as wall adapter. Wall adapter that ships with the phone is NOT 3.0, so what are you trying to prove exactly? Wall adapter charges at 2.0 amps.
Please stop misinforming people, it's nothing personal, just trying to state the facts. See attachment

You need to contact Samsung and let them know this, I'm not sure they're even aware of this feature.

chill guys, its cause QC is backward compatible.. so using QC3.0 you will get fast charging up to QC2.0.. not too sure about USB-C PD but i can confirm when using USB-C PD charger, you will get fast charging as well.. not too sure which is faster.. probably the same if the charger can charge up to 15W which is the official max charging speed for S10 btw.
edit: i use the same USB-C PD charger for nintendo switch and S10+

I called chief, he said that we were chill, and that the phones charging capabilities was already stated in this thread. Thanks tho

Obviously Quick Charge 3.0 would be backwards compatible with Quick Charge 2.0. There's no such thing as "Quick Charge 3.0 only." If there was, boy would we have a lot of fried/exploded devices as they received more current than they were rated for.

Haha did you guys even look up what QC 2 and QC 3 were? They aren't that much different, just the step size. Both have a max of 18 W. You would need a volt meter to prove the phone was QC 3 compatible, showing it charging at a voltage that was not near 5, 9, or 12 volts. As far as I'm aware, the S10 either charges at 5V with Fast Charging disabled, or at 9 V if fast charging is enabled. That would adhear to the QC 2 spec, not the QC 3 spec, since it can't do voltages between 5 and 9. If the S10 gets an update for 25W charging, I believe it would charge at 12 V. Still, only QC 2 compliant, but not QC 3.
USB-C PD can go up to 100 W. I think 45 W and 90 W for laptops is pretty common. The Huawei P30 Pro can supposedly charge at 40 W.

Guess they were having a hard time understanding that QC 3.0/2.0/whatever give the fastest charging speeds that S10 can handle.
On my S9 with Nintendo Switch USB-C PD charger I couldn't get 15w, just 10w (aprox. 5v and 2a).

Thats likely because you have fast charging disabled. USB-C PD chargers should be capable of charging at 9V 1.67 amps (15W) the same as any QC 2.0 or QC 3.0 or Adaptive Fast Charging capable device. They are just different standards.

Haven't tried using the original charger yet, but my s10 charges on my usb pd capable charger for about 1hr and 20 from 15% to 100%

I'm able to charge up my S10 with a QC. 3.0 power bank and car charger in about the same time as the stock wall charger.

Charging with Power Delivery

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

Oh awesome, what charger are you getting those speeds on if I may ask?
You might've just helped me to make my final decision to get the 9T Pro then. The only thing I'm still hesitant about is the lack of HDMI-out and color-notification. If this phone had color notification and HDMI-out... my lord.

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

Thanks for your reply. Do you know if there is any chance to read the charging voltage from the phone? Or the only option is use an USB multimeter?

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.

33W Charger

Are there any other devices with the same power output? I have various Oneplus chargers, and a couple of Quick charge 3.0, but would like a spare fast charger.

You can buy the xiaomi 27W QC4 charger it does 27-35W

realme x2 pro has 50W, so something there shud fit

I've tried various chargers but the SOC was >85% so it wasn't a proper test. With most charger (QC or PD) I've gotten 15W, including with my 65W PD laptop charger. With the original charger I got 20-22W. If it's important to check the power, I can wait until it's discharged and redo the tests, which I plan to do anyway.
For travelling, I find it a lot more useful to have the 36W (18W QC + 18W PD?) cheap Amazon charger with 2xUSB-A and 1xUSB-C, which has the same size as the original charger: https://smile.amazon.de/gp/product/B07WFDTJFR/

Let us know how you get on. I tried my Samsung 25w charger, Pixel 3 charger and the Motorola 18w charger. All of them charge at 12-18w only. Stock charger goes to around 27w

I've now tried all the chargers and powerbanks that I have, QC3 or PD. All of them cap out at 16W, even though they can deliver more. I got the original one to charge with 30W (at 60% SOC).
The original charger is marked QC3 but they are probably not following the standard.

From my understanding the Snapdragon 732g has Quick Charge 4+ support doesn't it ?

Yes, i've noticed the same. Around 27w max. Today i was charging my phone and observing the batt temperature. Kinda obvious, but the hotter the battery gets, the lower charging power it will deliver. Here in Brazil the temp this week is being around 36-42°C, so i put the phone over a bar of artificial ice. As the batt temp went under 35°C, the resultant "charging current" went to around 5500-6000mA. Doing the math, it was possible to arrive at the 27w result. (~4,5V x 6 = 27w).
When the batt temp was near 38~39°C, charging was down to 2000-2800mA (resulting to around 10-12w).
I also found something strange, it wasn't able to show the charging percentage with 2 decimals, as shown in this video:

Question How can QC 3.0 chargers fast charge the phone?

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%?
