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

Well maybe I should grab a 6P charger and test it
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.

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
Sent from my ONE A2005 using Tapatalk
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?

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?

Hello,
I read in an article somewhere that the Nexus 5X has Qualcomm Quick Charge capabilities on the hardware side, but not on the software side. It also stated that this possible could be activated in the future. For the life of me I can not find the article now, but I did hop over to the tear down page that iFixit did on the Nexus 5X. Sure enough, the 5X does have the Quick Charge 2.0 chip on the logic board.
https://www.ifixit.com/Teardown/Nexus+5X+Teardown/51318
I'm not sure what this means exactly. Isn't USB C pretty much as fast / faster than QC 2.0? Or, would QC 2.0 via USB C be even faster?
This phone will never see qc. Google is all about open standards which is why it has usbc and can charge at 3amps.
Sent from my Nexus 5X using Tapatalk
God can people just stop with quickcharge?
The device is charging at 15W at max allready, and thats just for a short while. The majority of time charging is spent under 10W (2A).
QC is not magic and wont make a difference for N5X. My M8 with QC and the same battery capacity charges nearly identicaly as to my N5X (same battery capacity), it just goes 9v for a shorter while but the total wattage never goes above 15w for QC charger.
I feel like the desire for qualcomm quick charge is so that people can use the wall plugs and car chargers they already own because the adapters that actually support the usb c standard are few and far between or really expensive from Google, it's not about which one is better or faster.
Sent from my Nexus 5X
That chip is a power management IC with QC features, does not mean LG/Google even hooked up the wires required to use it or put in the additional components that might be nessasary to make it work. I don't think Qualcomm publicly releases data sheets so we can't know but I doubt the hardware as a whole supports it.
In case anyone is interested. I have a Quick Charge 2.0 certified car charger and it works with my 5X. It enables "Charging rapidly". Same thing with my Note 4 rapid charger. Both work fine.

Hove you looked at the actual charging rate at all? Just because "charging rapidly" does not mean it is truly charging as fast as it should.

I'm gonna answer this even though I don't appreciate your tone. So I'm doing it for the benefit of others. Yes it does charge at a fast rate with all three chargers (stock, Samsung Fast Charger, and QC 2.0 charger). About 1-3% per min and it slows down, as it should, when above 80%.
And "Charging rapidly" wouldn't get triggered if the power management charging circuitry didn't detect that the charger had the proper dynamic output voltages/currents, with the power output being P(t)=V(t)*I(t). Your "rapid charger" will have two pairs of output ratings for current and voltage (some have 3).

I'm not trying to be mean and I did not intend to have a negative tone so I'm sorry for that, I just wanted to see the actual numbers when using that charger you mentioned and see how they compare to the OEM charger because from what I have read charging rapidly is faster than normal but has a very wide range that can trigger at much lower charging speeds than the OEM charger.
Sent from my Nexus 5X
All of my testing on "charging rapidly" indicates that the phone is charging at 2.1A, not QC 2.0.
I suspect most QC 2.0 chargers offer 2.1A charging for when an iPad is connected, to prevent the user from returning the charger because it didn't charge their iPad. Google probably exploited that by simply telling the Nexus 5X to accept the iPad 2.1A handshake, which doesn't require QC 2.0 to be enabled.
It is possible QC 2.0 is just disabled in the baseband, but considering the backlash that Google got... I suspect they would have at least committed to enabling it, if that were an option.
That makes sense thank you

as i suffered around the internet looking for fast charge in oneplus 2.... people had two comments over this issue
1. oneplus didn't bought the liscense from QUALQUAMM for FAST CHARGING...!!
2. oneplus 2 didnt had the hardware support...!!
apart from this these things i also know that the cable and charger isn't enough for fast charging....!!
things to know:
1. cable isn't capable of delivering the necessary power for fast charging... check below
http://www.theverge.com/2015/11/16/9742360/oneplus-usb-type-c-cable-adapter
2. the charger that oneplus provided is a (5v , 2A) charger which common now a days
things that need to tested by the developers:
does the DASH CHARGER work on the oneplus 2..??
CONCLUSION:
If oneplus didn't had the license agreement of QUALLQUAMM QUICK CHARGE last year since due to the money issue or due to the delay of this DASH CHARGE tech which should have came by last year........!!! so now the company has the tech of its own.... so why cant they give an update to the oneplus 2 and allow users to use DASH CHARGE...!
" dont say that ONEPLUS 2 dont have the hardware things.... it has it...."
"IF ONEPLUS give the DASH CHARGE to ONEPLUS 2 over an update it gonna stand till"
i had the same thoughts !! let me have a look at kernel sources released for oneplus 3 ! may i can make it work !
thanks ! will report back soon ! for both hardware and software updates !
How do we know the USB-C port hardware on the OnePlus 2 is designed for 5V/4A? It might be designed only for 5V/2A in which case, using 4Amps will kill the port entirely and ruin the device. Design decisions like these are thought out months before production.
Dash Charge is basically OPPO's VOOC Charging.
The major difference in the USB C port being, is that it contains 7 pins, instead of the standard 5 pin layout. There are two extra power pins. That is why it requires both the adapter AND the cable, while Quick Charge 2.0/3.0 can work with any cable.
So no, it is not going to work with Oneplus 2. It's not a software feature that you can just enable.

There is nothing like what you are saying.....!! It's a software update and a hardware change which is changing the charger and the data cable.... check out the power delivery of the qualquamm quick charger vs the oneplus 2 charger.....
Yes it's a software and a hardware change.
Change your current hardware (phone) for a hardware that support quick or dash charge.

what will happen if i charge my one plus 2, whose earlier charger was 5V and 2 Amp and now dash charger is 5V and 4Amp. will it damage my phone.
I have tested the dash charger with the OnePlus 2. Nothing spectuacular happens besides the fact I have topped 2 amps for the first time using the Dash charger. The OnePlus limit for charging is 2 amps. Usually I get 1,2 - 1,8 amps on a regular 2 amp charger. The OnePlus 2 charges a little bit quicker and more stable with the Dash charger, but thats about it. Don't ever expect the same speed as on the 3 and 3T.
Charging current depends on battery level you only get 2A at nearly empty level then drops little by little

I guess they might have limited the current to prevent overheating. It heats up like hell even without fast /dash charge
It confuses me why a phone with a USB Type-C port would ship with a Type-A to C charging system. Beyond mere speculation, does anyone have information on why this was done? It doesn't make sense to me.
Also, has anyone tried a Nexus/Pixel type-c charger with the OP5? How are the charging speeds on those?
Thx
Because only a small number of users have computers and spare chargers with type-c ports? Even big brands do this: Apple uses a type a to lightning and Samsung type a to type c. This will change when type c is more common.
Regarding the charging speeds, Oneplus uses a proprietary technology, so it's only possible to charge at "dash" speeds using the original cable and charger. If you use other cable (or use the original cable, but not the charger) it will be 2 or 3 times slower. It all depends on the power output of charger you use.

I've read places that OnePlus moved the fast charging tech from the phone side to the charging brick side. This is what also allows the phone/battery not to heat up during charging. It don't think the phones could handle charging at these speeds without frying the phone (phone would fry an egg) if the tech was still inside the phone.
All I don't understand why cant we charge this phone with QC2/3 chargers as fast charge because the SoC needs to support it?

This is what really gets me. Lots of people have QuickCharge chargers from other phones over the years, and it's easily supported by the hardware OP uses.
Dash Charge and Quick Charge are different things. Each technology needs different hardware to work.
Quick Charge was created by Qualcomm and it's used by the best Android phones (Samsung, Nexus, Pixel, etc)... it's slower than Dash and manufacturers need to pay a fee to Qualcomm when they use their technology. We can find support on power banks, car chargers, usb hubs, computers, etc.
Dash Charge was created by OPPO, Oneplus parent company... I guess this and the need to save money are the two main reasons for them to use Dash over QC.
Dash is faster because it moves some hardware from the phone to the charger. This way the heat generated by the higher voltage and amperage is "stored" on the charger allowing the phone to receive more energy and charge faster. The downside is that it's almost impossible to find compatible power banks, usb cables, chargers, etc.
There is also some concerns from users about the battery life... Oneplus says there's no problem, but everyone knows that charging batteries very fast is bad for their lives... anyway, most of us don't keep the phone for more than 1 or 2 years.
Then there is the "normal" charging, used by Apple and by cheap phones and usually can go up to 5v ~ 2.4a. This is also what the OP3/3T/5 uses when we don't use the original cable+charger.
Apple for example cannot use QC because they make their own CPU and don't use Qualcomms chips. Samsung also have a different tech they use on phones running on a Exynos processor.
tl:dr:
Quick Charge: from Qualcomm, slower, the "smart" hardware is on the phone, hotter phone during charging, colder charger, way more popular;
Dash Charge: from OPPO, faster, the "smart" hardware is on the charger, colder phone during charging, hotter charger, only OPPO and Oneplus use it;
Normal charging: it's slower, there is no special hardware needed, works with everything;
I was studying this problem, people charge the phone with QC3.0 chargers and the phone stops charging, what really happens is that the zener diode that has the charging plate for security reasons (stabilizes the load voltage) Stop charging because the zener it's short-circuited (QC gives more voltage than it supports, is designed for 5v, there is QC of 12v or more). A possible solution is to cut the zener. (It works again but without voltage stabilization, it would be better to replace it but it is very complicated).
I leave some images for the one who has the problem and does not get the spare.
There is also a zener diode on the other side, on the motherboard, if cutting the zener in charge plate does not serve, check the motherboard zener.

Not sure but QC 3.0 charger does not charge your device at 9V or 12V until your device too has QC 3.0 qualified hardware(QC 3.0 circuit or equivalent) and software(kernel).
Cases like yours might be due to QC charger quality, which one did you use?
There are many low budget QC 3.0 chargers available like Aukey , Blitzwolf. I have Blitzwolf S9, charge my RN3 with it occasionally. And also I use MI Powerbank 2 (not 2i) for everyday charging and it is QC 3.0 input and output. Cannot check if my Zener diode is shorted but no changes in charging till now.
Charger's QC specialized circuit determine how much voltage (5v or 9v or 12v) and also current (~2A @5v or ~3A @5v or ~2A @9V etc.) should be given to device after detecting phone's charging circuit. So low budget QC 3.0 chargers may cause voltage or current rise.
And for RN3, do not set current (in any kernel) at 2.4A (it will cause damage due heat which is main culprit in long run) , 2A is sufficient but kernels with some ROMs (like NOS 8.1 for me), it charges at 1.4-1.5A. In such case, you can flash other kernels for fast (2A) charging.
My Mi Powerbank 2 charged my phone at almost (2A) in RR, Lineage 14.1 , lineage 15, pixel experience 8.1 roms.
Now in NOS 8.1 it charges at 1.4A in average.

For me the chargers detect the snapdragon 650 and send more power, the zener diode must support 10w only( i think no found info), I have comments above saying that they were burned with chargers QC, I'm trying to determine if qc 3.0 or 2.0

Charger's QC specialized circuit determine how much voltage (5v or 9v or 12v) and also current (~2A @5v or ~3A @5v or ~2A @9V etc.) should be given to device after detecting phone's charging circuit. So low budget QC 3.0 chargers may cause voltage or current rise.
And for RN3, do not set current (in any kernel) at 2.4A (it will cause damage due heat which is main culprit in long run) , 2A is sufficient but kernels with some ROMs (like NOS 8.1 for me), it charges at 1.4-1.5A. In such case, you can flash other kernels for fast (2A) charging.
My Mi Powerbank 2 charged my phone at almost (2A) in RR, Lineage 14.1 , lineage 15, pixel experience 8.1 roms.
Now in NOS 8.1 it charges at 1.4A in average.

i using NOS 8.1 with stock kernel and original MI charger 2A 5V, charging speed 1998mA from 10% to 50 % then slowdown to 1600mA aprox and 90 to 100% 600mA aprox
I activated 2.4A option in whatever kernel I used, but I dont rely on it too much.
Primary charger is HTC 1A, only use my Aukey QC2.0 when I need quick refuel. And my phone still rock stable though
Never burned mine out but I have a QC 3.0 charger and when I plug it to the phone it charges at the normal rate of 5v 2A, so I rarely use the QC port on the charger since it's the same as using the stock charger or normal ports, my guess is there are many custom kernels causing this damage, and I think there was one rare miui beta that enabled it at one time, I'm not sure if there is fake QC chargers but I believe real / official ones the circuitry is made by qualcomm and it does a series of checks to see if the device can support it or not-which it never did activate on my QC charger at least (I have a Choetech QC charger that cost around $30), which was pretty costly considering I never got to use the QC feature, but I think it's well built and never gives problems so in a way it was worth it and it's available if I get a device with proper QC support.

kernel can allow charger to pump in high current
many users have faced this
some carelessly do it knowingly
hence, AGNi limits it at max 2100mA no matter how badly users want to use QC currents.
