Unlike redmi 3 , 3S models are powered by a SOC that supports quick charge 3.0 but there is no mention of it in the phone specs
Yes, it unofficially supports QC 3.0
unofficially? It seems strange that they wouldn't advertise it but in any case ... are you saying that with the appropriate charger this device will charge fully within the hour? Have you tried it yourself?
I dont think it supports qc 3.0 cause if it had supported it xiaomi would have said that and its price would have been higher as hugo stated in redmi note 3 launch event that they have to pay some extra money to qualcomm to activate qc 3.0 and that they did not put qc 3.0 to keep the device cost low so in my opinion they did the same with redmi 3s to keep its price low they did not put qc 3.0. Instead there maybe qc 1.0 or 2.0
If the SoC supports QC 3.0, it doesn't directly mean the device will support it. It's like saying, SoC supports 21MP camera, so device must have it. lol.
BTW, if 3s had supported QC 3.0, then Xiaomi would have marketed it nicely. You know, how good they're at marketing.
Really missing QC3. It would have made charging time much lesser.
I understood that it would have it and ordered power bank and charger that supports QC3. They charge it approx. 40%/hour, and Ampere shows it taking 2A/5V. Does this mean it supports it? I don't know :laugh:
One thing also is that my charging cables aren't high quality so they might be restricting it.

Thats not Qc 3.0 its Qc 1.0 which is basically very slow.so dont get your hopes up.redmi 3s and redmi 3 and redmi note 3 all supports Qc 1.0 only

I don't know if I would call that very slow but yeah I'm a bit disappointed. Maybe in the future with custom kernels or something.

Yes with custom kernel we can achieve charging speed as fast as that of Qc 2.0 but not 3.0 . But still we need a good developer for that.hope we get one.
No.. Doesn't support quick charge officially
According to this video it charges in ~2 hours 30 minutes with a quick charge 3.0 enabled charger vs ~3 hours with the included 5V 2A charger.
https://youtu.be/5eASPZ70Sws
Looks like it already support at 6least QC2 standard as volatge upto 9v are achiEved by qc 3 charger .
Though soc support qc3 but I think we need a custom keral to support qc3
With qc 2 or 3 charger a depreciation of half hour charging time is achieved already as shown in video link above. With custom kernal another half hour with qc3 charger will not be difficult
I think this device has great future as developer favorite device
Let XiAomi release it's sources and unlocked for boot loader

Xiaomi does not want anyone to unlock its bootloader. They made it over complicated.I don't think they will release unlocked bootloader ROM even though device specs are good.

so you have filled the form and you got the sms with the "ok" for unlock ?
which rom do you have ?
you have official rom or unofficial ? (if you have unofficial just don't ask , of course you can't unlock with this rom)
if you have official , i think (well i don't remember exactly) is that you must (or is just better) switch to dev rom for the unlock , not stable
No. Xiaomi maybe cost down something.
The reason they're not advertising QC3.0 support is they'd have to buy the license to do so. And since this is a budget series of phones, they have to cut the expenses as much as they can. I tested it with a QC2.0 charger, and the phone charged at 9V, don't remember the amperage, though. So it supports at least QC2.0.

i have this feature on my phone's kernel atm, is it actually safe? because Redmi 2 itself doesn't support fast charging by default will it cause our battery to overheat? or even explode (lol)
Redmi 2 supports quick charge 2.0, however the charger sent by xiaomi does not have this technology. And yes, that support in the kernel is secure.

The Redmi 2 battery only accepts 5V/1.0A, so QC 2.0 isn't supported by hardware, altought the SD410 supports it.

Yes, but using a quick charge charger makes the battery charge 1A / h constant, which makes the charging much faster than using the charger sent by xiaomi
The Xiaomi India website doesn't mentions that it supports Qualcomm Quick Charge but there are some people who are saying that it supports Q.C. 1.0/2.0 and some even saying that it supports 3.0.
And the Xiaomi website states that “[it] Comes with 5V/2A quick charging to charge and go with minimal downtime.”. Interestingly enough, Quick Charge 1.0 also charges at 5V/2A.
Has anyone tried charging with Qualcomm Certified chargers and is there any long term issue like battery inflating, poor battery backup, etc?
And if it does work then what are the things I should be looking in a charger when buying apart from Qualcomm certified chargers?
The soc of our device does support quick charge, but to enable it, we need a suitable kernel
I think it's enabled on MIUI developer rom.

Yes. Some say that latest beta update miui 8.2.5 has total charging period of 2.5hr.
As per the super moderator in MIUI forum the Dev rom supports QC 2.0 and charging time is less than 2 Hrs.
Hello guys.Today i had my Redmi Note 3 Pro repaired , because a chip/module (that is responsible for charging) burnt down.
To avoid this:
1.Lower your charging rate (stock 2000 mAh).And yes , i was using stock rate.
2.Use only original charging adapter.And yes i was using charger and cable out of the box.
3.Try to avoid gaming while charging ,because the phone heats up so hard, especially screen.
I was using Resurrection Remix OS ,but im not saying it is responsible for this cause.
And here is some additional information from georgek1 on miui forums
For those who don't know here are some things about QC and Xiaomi Redmi series.
Quick Charge (QC) is a patented technology by Qualcomm (the company behind the Snapdragons processors) which allows phones to be charged faster. Quick Charge comes in 3 versions (time values are for a 4050mAh battery) :
v1.0, released 2013, using 2.0A -> full charge in 2.43 hours
v2.0, released 2015, using 3.6A -> full charge in 1.32 hours
v3.0, released 2016, using 4.0A -> full charge in 1.215 hours
* QC 2 has backward compatibility with QC 1 and QC 3 has backward compatibility with QC 2 and 1.
Redmi Note 3 currently implements QC 1 or a similar Xiaomi-made technology that charges phone in 2A.
Quick Charge (in general) implementation requires a few things:
A processor capable of Quick Charge technology
An extra electronic circuit on the mobile motherboard
A Quick Charge capable/compatible charger + a good cable
Drivers (software) on Android ROM kernel
A license fee that is paid for every device sold with Quick Charge technology enabled
The most important thing is #1, the processor as is the base (heart) of the system. Redmi Note 3 Pro with Snapdragon 650 supports Quick Charge 3.0 as the 650 snapdragon is capable of this technology. But let's see all the requirements:
Snapdragon 650 supports QC 3 = OK
Extra circuit on motherboard = UNKNOWN (probably yes)
QC charger and cable = NO
Drivers on kernel = NO
License fee paid = NO
* Some people say about batteries. QC doesn't require any special designed batteries. It works with all batteries on the market. That is it's goa,l to implement faster charging with current battery technology.
OK now, drivers are missing 100% and it has already confirmed by author or RADON kernel (@Umang96). His words:
this kernel at present does not use any charging driver hacks, I did try adding charging hacks in past but they did not work well and seemed ineffective, thats why I decided to keep charging drivers stock (same as xiaomi). We still get 1700-2000mA charging rate with stock charger which is good enough. Also, I don't recommend anyone to buy QC2.0/turbo/fast chargers, I use the stock charger and cable only.
Although QC has been originally enabled by @Umang96 in RADON kernel, he has later remove it. That makes me feel that QC 3 or 2 implementation in Redmi Note 3 is not possible due to software/kernel (#4) missing drivers or due to lack of the extra circuit required in hardware level (#2).
Why Redmi note doesn't have QC by default? Here is my guess:
The extra hardware circuit on motherboard may cost around $1
The QC charger will cost like more because it includes a) an extra circuit inside the charger $1 + b) license fee paid to Qualcomm for every charger $3
At least $3-5 fee for Qualcomm for every device sold with QC enabled.
That makes an extra $7-10 on factory level cost. An extra $10 for million devices is a big number. Also, that factory costs will lead to an extra $20 value on the consumer which makes the phone more expensive for its category.
Also my final guess is that Xiaomi wants extra things enabled for "Mi" (the good series) of phones in order to separate them from the cheaper "Redmi" series phones.
It would be very nice if QC-enabled processor phones which has QC disabled by factory, to have an option (like an application) which will allow users to pay the licensee fee and enable the QC option. I would be more than happy to pay $10 even $15 with my credit card to enable QC in my phone.

Have a good time using this budget masterpiece!
QC2 and QC3 are 9V 1.5A usually, there is no 3.6A or 4A.
Latest radon supports QC.
QC works but it's not properly slowing down with usage and instead going up, that's why your charging port got damaged.
If using QC phone should be idle or used very lightly, if you plan on using the phone you need to charge with non QC charger.
Your answer is in your post itself:
Snapdragon 650 supports QC 3 = OK
Extra circuit on motherboard = UNKNOWN (probably yes)
QC charger and cable = YES ( I have QC 3.0 cable and charger and most people use it too)
Drivers on kernel = YES (use custom kernels to support it)
License fee paid = NO ( Does it really matter as an end customer? )

I've using QC from the day it was supported by the custom kernels like Radon and others. So far, there are no issues with the charging etc. My RN3 is 13-14 months old now as I got it the day it was launched.
End story: it's just bad luck.

Fast charging has been most controversial topic for our Mi A1 device.
Is it possible to enable fast charging on custom ROM.?
I have read somewhere that our SoC supports Fast charging

It was a bug, MiA1 do not supports Quick Charge.
Yes I should think fast charging would be available on custom ROMs. We saw on phones like Redmi note 3 it was also enabled. Basically Xiaomi phones have all capabilities to fast charge, however the speculation is Xiaomi does not pay Qualcomm the license fees so they can't officially support it.
Hello, i have an aukey usb quick charge 3 charger and now that i have a new xiaomi mi a1 i bought a nillkin usb type c 3.0 quick charge cable.
Even tho i have a charger and a data cable compatible with quick charge, when i charge it says "charging", not fast charging, i don't even sense a notisable decrease of charging time.
So i am doing somethong wrong? It is suppose that with oreo update quick charge is aviable on the mi a1.
tired reply , please search.
The 'fast charging' message was a bug. Congrats. U just waste money
Sad to break it to you, but the phone doesn't support Quick Charge 3.0
Who except pajeet analphabete on Indian blog said it was supposed to get QC?
I've read that one of the Oreo beta builds had quick charging enabled by mistake and Xiaomi removed it later, this is when/where rumors started. No idea if that's true though..
There is a quite big difference between "fast charge" and "quick charge" (by qualcomm). Quick Charge will not be enabled on those phones as qualcomm wants money for each device that uses it. However in oreo we have "fast charge" enabled.... also to have quick charge you'll need charger that has the qualcomm chip in it... and for the fast charge again you'll need charger that supports fast charge(basically that it is more powerful - 34W and up).
And remember it is android one device so it is as close to the aosp as possible and many of the settings are up to google to change (like the cam api 2)
I don't get the fuss around this "fast" charge "enabled" thingy. I'm using a nexus 5x charger since day 0 (back when only displayed "charging") because i've bought it as a replacement for my nexus 5x.
So, the output of the 5x charger has 3A . Now pay attention, the A1 (at least mine and i don't think i got a special edition) was charging with 2A out of the box (nougat) and also after oreo update, period.
Mi a1 does have sd625 which supports fast charging but xiaomi hasnt enabled it cause enabling that will make xiaomi pay some loyalty to snapdragon. So they didn't enable it. NO FAST CHARGING ON MI A1
This thread reminds me of countles indian videos trying to prove redmi phones support fast charging by comparing charging speeds between stock 1A chargers an qc2/3 ones. Good stuff
With custom roms and root, could you re-enable it? Yes.

Redmi note 5 has the icon of fast charging with micro usb, but Mi A1 with usb C does not, lol. My phone Mi A1 charges fully within 1 hour from 1%(would say... 40min) with an aukey QC 3.0 and a blitzwolf amp usb cable.

Don't worry about people bragging ie lying about how their phones charge up faster with quick charge. Or some sort of forced charging is going on which isn't good for the lifespan of the battery. Samsung allows users to turn off fast charging in the settings to reduce excessive heat which says something about fast charging.
So you guys are saying it doesn't support Quick Charge™. But I just downloaded CPU-Z for fun and it read the fact that the MI A1 - My unit at least runs Snapdragon 626 as opposed to what GSMArena says (625) and according to this article it is supposed to support it. I don't have a fast enough charger - Never thought I'd need one since the phone supposedly doesn't support fast charging, but if it runs 626 it might. If I can edit this post I'll add a screenshot from the phone in a moment.
Can't seem to add the screen shot, so here's the link to it:

yes. I'm using a motorola turbo power charger and a magisk module 'force fast charge'. getting ~2000mA.

Dang, I JUST BOUGHT 5. QC3 chargers!!!
... I just read on some other forms that the mean one supports fast charging qc3 charger I bought a bunch of chargers. does anyone know will queue c3 chargers work on all types of phones and devices even if they don't have any Qualcomm chip in them will they still charge at your 1 amp or 2 amp speed?? and that's question does anybody know what happened to the license agreement between called come and show me about working out the deal to get the Alt-X low-latency and the Ap-X codec license agreement???
