Quick charger 3.0 - Xiaomi Redmi 4 Prime Questions & Answers

Hello,
Anyone know if Redmi 4 Pro have quick charge? I buy a quick charger 3.0
Thanks

My moms Redmi 4 Prime does benefit from using a quickcharger compared to the one in the box. Don't know if it is full QC 2.0 (because that's the most the SD625 supports) speed though. It's btw one from the brand Blitzwolf that she has, so officially licensed by Qualcomm.

I dont know abt QC2.0 but w/ std 2.0A charger mine can charge 15-95% in 2hrs. I don't recommend QC because they heat up yr batteries, heat is no 1 enemy of any battery.

[Q] fast charge Q

Is that feature packed entirely in the Battery or is it built into the phone?
So if I buy extra batteries (official of course) Will they get that fast charge bonus in an external charge case?
(ie the note 4 version of this http://www.samsung.com/us/mobile/cell-phones-accessories/EB-K800BUWESTA )
the quick charge isnt built into the battery it is built into the qualcomm 800+ chips
ahh ok.
thanks for that answer.
Will it work with wireless charging assuming there is a wireless back cover?
I just went to a note 4 roadshow in Montreal and for the fast charging you need the Note 4 charger. It will charge at regular speed with other chargers. Not sure if the Note 4 charger works with other phones.

Did you see the amp of the note 4 charger?
Note 4 charger will still be micro usb so it should work. The key is the fast charge is built into the qualcomm 800+ chips which allows it to accept. Higher voltage rates...I could be wrong. It's partially the reason I have note 3 and note 12.2

Read somewhere that quick charge in note 4 is samsungs own implementation via charger, so it would work on both soc

Quick Charging OnePlus 2 possible with Nexus 6P charger?

Hey everyone, The OPT charger is around 10W (5A x 2V) while the Nexus 6P charger is 25W. Both devices have the same Snapdragon 810 chipset and they both use USB Type-C. Is it possible to get the Quick Charge functionality from the 6P (0 to 100% in around 90 minutes) to the OnePlus 2?
Thanks in advance
No, op2 doesn't have quickcharge built in. You might break your battery.
Energy don't work that way.
Think of your opt charge circuit as if it is a water hose, battery is a little container, charger is the big container.
It doesn't matter how big is the charger container the hose will take the same time to fill the small container.

Couldn't have said it better myself
Quick charge is a built in feature which is not included in op2. So it's not possible to charge it that way.
I believe the snapdragon 810 supports quick charge, however, the OP2 designers chose not to implement it, probably due to the increase in cost associated with upgraded current handling for some parts, but that's a guess on my part.
There's usually no problem with using a larger capacity charger with your phone because they're almost always self regulating. However, it will probably not accelerate charging unless the device supports it.
No it doesn't support it.
My OP2 charges in 1hr50mins to full.. I am satisfied with it.

The nexus devices don't quick charge, they however charge quickly (called fast charging) with the new type C connection via a 15w 5v/3a charger. It's a non proprietary open standard and not a Qualcomm certified type of deal. The question is legit, you could be able to get a quicker charge with the nexus charger.

Yes I know that they don't use Qualcomm Quick Charge but some fast charging that's possible because of USB Type C. So that's why I asked if the OnePlus 2 could also use the ''Fast Charging'' capability from the 6P

Quick charge/fast charge whatever you want to call it won't work, opt circuit/controller is designed for 1A current, it won't demand any more than that.
You can have a custom kernel that tells the controller to not "shutdown" with more than 1A but is your risk and probably won't speed up the charging process by much.
Opt charger is 2A and should be enough to test a kennel tweak, again changing just the charger won't work.

I wonder if it is possible to some how forcefully enable quick charging somehow.

How is OPT circuit designed for 1A?? then why would they make a 2A charger, that makes no sense.
Fast charging on nexus devices is a capability of usb-c, not snapdragon quickcharge.
So I think we need to reevaluate this..
Somebody needs to test with a 3A nexus charger and run ampere.
Sent from my ONE A2005 using Tapatalk
I might be wrong in something.
I used ampere to "measure" the current always tops at 1090mA but with screen on, which also drains juice from charger.
Any way you need a custom kernel like boeffla to change the mA to charge I remember it tops at 2200mA
But a 3A charger like nexus will only supply what the device is demanding (2200 mA)
Fast charging on nexus it's a feature of charger and charger circuit, remember to have a puppies a ***** (female dog) needs to mate with a dog not a cat. You might force different species they could mate but won't breed.
You need any race of dog to have puppies.
The same you need any brand of 5V/3A charger for a nexus and you will have fast charge.
Opt don't have fast charge won't harm to try but don't buy the charger just to test borrow someone's

Opt supports 5v 2amp charging on screen off.
Quick charge (Qualcomm quick charge®) is achieved raising voltage and not amperage (up to 20 volts, in qc3) and should be both hardware-supported and software-enabled since is the phone that asks the charger for a specific power level (volts-amps couple).
The real question is: is qc hardware supported on opt, and, if yes, could it be software enabled in some way in a custom kernel or so?

You might blast your USB port if you are overcharging more than 2A.

thanks God someone replied, it's a shame that this does not contribute to the discussion in any way
I found an article that says that you need Qualcomm PMI8994 Power Management IC and SMB1351 (as well as snap 810 SoC) to get quick charge working... I can find the first in many teardown but I can't find the second, any idea? Maybe it has been replaced by another component or is it missing at all?

redmi 2 fast charging, is it safe?

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

POWERBANK for S7 EDGE with FAST ADAPTIVE CHARGING SPEED

Hi all,
I want to buy min 20000mAh capacity powerbank for me and my wife's S7 Edge phones and capable of fast charging both S7 Edges simultaneously.
I already bought Anker Powercore Elite 20000mAh ( https://www.anker.com/products/variant/PowerCore-Elite-20000mAh/A1273011 ) but, it does not charge them with fast charging !
I tried many cables (all of them orginal and official) but the results are the same: "cable charging" !
So, can anyone suggest me 20000+ powerbank with fast adaptive charging for S7 edge for sure, even better if real user with real experience?

Thanks. I checked it out but not enough for us :/
Also, it is surprising that Xiaomi can support fast charge for Samsung S7 Edge but Anker can't !
Mine was Anker Powercore Elite 20000 and had 3 usb output, total 6A. If 2 phones charge at the the same time, 3A for each.But still says "cable charging" :/
My orginal samsung fast travel adapter is 2.1A and says "fast charging"

Are u sure the Anker that u bought is fast charging support ? Try with different cables bro. I will check for a 20000 mah MI PB and give u link
Your Anker powerbank doesn't support fast charge.
Samsung fast charge work by increase voltage from 5V to 9V but lower current from 2.0A to 1.67A, which give the total power of 15W (9V×1.67A) up from 10W (5V×2.0A)
So for powerbank to support fast charge, it must be able to output 9V.

Thanks for the advice.Yes i checked that out also and it supports quick charge only if 1 phone is charging.
But i decided to buy Xiaomi Mi ( 2nd Gen) Powerbank 20000 mAh. It has also QC 3.0 and almost half price cheaper. I read the comments about it and most of the users are happy.

Nexus 4 charging rates question.

Hi there. I was curious for those of us who still use a nexus 4
What charging rates do you get? The maximum i have ever gotten is 850mah via main wall socket with an official Qualcomm quick charge three one. even just a cheap charger i have around gives the same maximum charge limit
At 50 % charge it tells me an hour and a half to full. Its a long time
My cable is rated to 1500 as another phone hits 1350mah charge. With the same chargers
Please do let me know what you've gotten and if its more.
Also if any of you have exact quick charge 1 specifications, let me know. Or specifically how it works.
I used ampere to check. I know that fast charge is only for usb.
I use a 3rd party charger and Max charging current is ≈860mA

That seems about on par to what I've always had. I've seen mine hit 870. But not often. I guess thats just the maximum of qc 1.
