I ask this since it seems more feasible than enabling something like Quick Charge 3/2.X since this method is open and not proprietary.
It also seems feasible since the OnePlus 3 can clearly handle up to 4A of current at 5V (dash charge) so in terms of hardware it should be able to handle 3A at 5V similarly to the Nexus 5X/6P via the standard USB-C spec.
It doesn't even seem to be able to handle 2.4A via a USB-A to USB-C cable, or even via a USB-C charger using a USB-C cable.
Is there some hardware or software limitation I'm perhaps missing? If it's a USB-C device it should be able to charge via the USB-C standard
To my knowledge one plus promised dash source by the end of July. Also to my knowledge is something must be enabled and PCB hardware must enable fast charging. Galaxy s7 doesn't have qc3.0 despite having the correct hardware.

i do understand something needs to be enabled for QC2/3.X but why for USB-C?
Short answer ... no one knows and they're talking out of their ass ...
Long answer - Even if its a hardware/software enabled type feature - most do not know how to program it well enough to incorporate it. So everyone has to rely on source code with it already programmed to include it with any rom. Some guys can program it but dont have the resources and/or phone to do so. The average programmer reading your comments doesnt know specifics which is why you get a lot of "to my knowledge" "as far as I know" "in theory" type statements

Quickcharge is closed and proprietary, it's just the licensing is cheap. It only work on phone that have recent qualcomm SoC. Yes our OP3 have a SD820 but the manufacturer also have to implement it in the phone, with software but also hardware.
It's a shame that Oneplus didn't use Quickcharge because with the price of one Dash Charger or VOOC charger you can buy a 6 port quickcharge 3.0 charger... And quickcharge can use standard cable (if you use another usb C cable than the one provided, the red and blue one, dash charge don't work even with the dash charger)
So I'll tell you one reason why the Oneplus 3 won't support quickcharge even with some hack : charging a lithium battery at a high voltage make it go BOOM!
Quickcharge use 9, 12 or even 20V to make charge faster (and it's an advantage with low quality usb cable). So the phone have to be able to convert 9 or 12V down to 4.2V and it's a hardware matter.
Now for the 5V/3A of the USB-C spec, it's Oneplus that limit it (and it's safer that way). I tested many charger with a voltmeter. I used some charger from 1.8A to 2.4A and it only draw 1.5A. I used a genuine apple charger at 1A (the A1400) and it only draw 0.5A, the same when it's hooked on a computer. With the dash charger and the dash cable, it go up to 3.5A. It's not 4A but it charge pretty fast. With the same charger but with a normal USB-C cable (2.0 and 3.1 i tried) it draw 1.5A.
So the dash cable use some extra pin to make the phone identifying the dash charger and the dash cable, when one is missing, it charges at 1.5A or even 0.5A.
Why Oneplus don't use the full 3A of the USB-C spec? Dash charge/VOOC I guess.

you can have BOTH. why REMOVE USB-C 15W charging?
charging slower is safer than charging at high voltage or intensity, I didn't imply anything else.
If the charger provided can do 5V 3A like the one provided with the Nexus 6P can actually charge at 3A a Oneplus 3, how can you sell a dash charger with a dash cable that do 3.5A (and the VOOC charger that is even more expensive and need a micro usb to USB-C adapter)

Easily? Dash charge is far more quick not to mention heat efficient
Also, slower charging is not safer by default -it's less hot charging that is safer more so,
Dash charge is heat efficient? Yes it will be warmer on a cold day. Like any battery charging slower is better for the battery life.
I don't understand your last sentence, sorry
If you are talking about the efficiency between the power on input and output from the charger, I think that the power is not high enough to really make a difference with a standard charger.
I am still a big fan of Qualcomm quick charge because I could use a 3 meter (10ft maybe) usb cable not even made of thick gauge.

I think what he is getting at is during quick charge the higher voltage results in more heat in the phone, with dash charge the heat is contained in the charger. Thus phone stays cool during charge which is safer for the phone.

Just got my 5x today, and it does "rapid charging" when I connect with the charger in the box, but when I connect using other USB cables/plugs (one supports QC 2.0, the other is a regular charger but supports 2.1A charging), I get a message that the device is "Charging slowly."
Are there other certain specs that a cable or charger has to have to take advantage of rapid charging?
Fast charging on USB-C is apparently very picky when it comes to cables. I havent't tried charging from the USB-A cables that I bought, but the reviews for one that I was considering said that the cable limited the charging capability to 500mA. I know little about qcomm's Quick Charging but I do know that it requires feedback from an enabled device before it will allow full power. I wouldn't be surprised if the lack of that feedback from the N5X was limiting current from the charger, but it definitely looks like a quality cable is the first step to success. Notice how thick the factory LG cable is...
Most cables limit current by a significant amount. Even factory ones. That's why the OnePlus One charger was so popular. The wall dongle was nothing special (2.0A) but the cable was thick enough to actually let it output that current. The only difference now is that our phone will actually tell us if it's hooked up to a crappy charger/cable.
Thanks for the reply, I'll have to do some hunting on Amazon for another cable and see what happens.
Appreciate it if anyone else can chime in too.
the Nexus 5X does not support Qualcomm Quick Charge, at all.
Thanks, I know QC is not supported, I was just offering up that I tried one, and that I tried multiple charges that support 2.1A charging.
Interestingly enough, if I use either of the QC certified chargers that I got along with my S6 (which only output 2A) I get rapid charging. Using an Anker QC charger (also 2A) I don't, and using a different charger (can't remember the brand at the moment, but also 2A, but not QC), I also get slow charging.
Hmm...
I know DASH charge is not supported on roms until later in July when the source is released but what are the charging speeds on various roms?
Do they get full charging speed at 5V?
On my oneplus 3 - Oxygen OS - I get 5V 1.5amps with the google nexus 5v/3a charger. In fact, it seems to limit charging speed to 1.5amps max for non dash chargers.
Can ROMs get 5v/3a?
Thanks,
Rico
Not until OP releases the source code. Hopefully by the end of July DASH charging will be implemented in custom ROMs.
The OP3 light ROM is basically custom stock and supports 5V/4A charging.
Not exactly what I mean. Can any of the custom Roms charge at higher than 1.5a at 5v? Most phones now can at least go to 2a if not 2.4a. Nexus 5x/6p can charge at 5v/3a.
Any Roms with charging rates above 5v/1.5a?
Any kernels?

i got that same observations too if some kernel is released which can take at-least 2A of current without the dash chargers it would be awesome as then we can charge fast from power banks too
I would love them to remove the 1.5a limit as it 'currently' stands... Crazy that they don't allow rapid charging that's possible with Nexus usb-c to usb-c spec adapters

Certainly you can do that. I was continuing to talk about how the Stock ROM from oneplus is handicapped by limiting charging that isn't Dash, to 1500mA max input current (as far as my observations and a quick Google have shown), just complaining about Stock basically... Java
I guess they want you to buy more Dash equipment instead of getting 3A rapid charge out of a usb-c to c spec charger
This is because the Limit of the cable. Most cables only support 1500mA. So to prevent it from smelting it will only Dash charge with a Dash Charger..

People tend to not understand that the limitation is there for safety reasons. You can't safely use all kinds of fast charging with all kinds of hardware.
DASH keeps the voltage at stock 5V and bumps up the current to 4A, which would destroy standard cables (too thin).
Other types of fast charging mostly keep the current lower, but bump up the voltage. OnePlus 3 *does not* support QC3 (technical limitation, not software) so you're stuck with 5 volts. And at 5V you can't safely go above 1.5A with any cable.
So, if you want fast charging, you have to use DASH or VOOC (VOOC accessories are confirmed to work as intended with OP3 and tend to be cheaper).
Sent from my OnePlus 3 using Tapatalk
Sure, I understand that, but none of this is what I'm asking as far as I'm aware. Let me say it like this..
I'm sat here with three Nexus chargers.
They output 5V at 3A (to a 5X and 6P) as per USB-C to USB-C spec.
I also have a PC motherboard with a USB-C port. It also conforms and allows 3000mA through the cable. Because all USB-C to USB-C CABLE is supposed to allow up to 3000mA by the standard. DEVICES can request that to be 1.5A or 3.0A.
The USB-C to USB-C spec cable is 3000mA
I plug it into my OP3 and it only allows 1500mA
I'm pretty much just *****ing at Oneplus for not allowing something LESS than Dash charging on a certified specification for the USB-C port.
We are taking 5V 3A USB-C spec (can't by design be thin cables) versus 5V 4A DASH (custom USB-A cable) which means NO danger of melting cables.
So is the OP3 port just not compliant?
To follow up from wiki:
All USB-C to USB-C cables are considered full-featured USB Type-C cables and must be active, electronically marked cables that contain a chip with an ID function based on the configuration channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB Type-C devices may optionally support bus power currents of 1.5 A and 3.0 A (at 5 V) in addition to baseline bus power provision; power sources can either advertise increased USB current through the configuration channel, or they can support the full power delivery specification using both BMC-coded configuration line and legacy BFSK-coded VBUS line.

So basically Oneplus in my eyes must have made a call to not enable 3A on a USB-C/USB-C cable, seeing as the in-device hardware is able to stomach 4A. It's just a matter of allowing communication to the USB-C spec charger to say, send 3A, I can cope with it.
I'd love to hear what you guys think.
I have a USB-C/USB-C car charger with 2x USB-A ports, and so i'm really bummed out that the OP3 won't accept the perfectly reasonable and safe 5V 3A it can give. I use the two other USB-As for other devices, so I don't want the single port DASH car charger from OP. It's a waste of space and investment...

I see that I forgot to mention another important piece of information before - the statement that I quoted here is not entirely true.
Remebrer that OnePlus boasted about keeping the device cool even while fast charging? Well, that's because they moved some of the hardware from phone to charger itself. Meaning that the phone alone does not have all the necessary internals to handle different charging inputs. Which is probably the reason that it only gives you 2 options: DASH or standard 1.5A @ 5V.

Yes, but literally three amperes is less than four amperes. The voltage is the same. There is no different internals technically required to intake Less then the maximum amperage, that's just plain electronics.
The issue with heat they quote is due to Qualcomm Quick Charge using higher VOLTAGE which means a greater 'pressure' of current. Higher voltage needs better internals, but both of what I'm talking about are 5V and need no additional hardware to receive LESS amperage of 3A versus DASH's 4A.
every new roms support dash charge now
Benson Leung said Google Pixel/Pixel XL Use USB Power Delivery up to 18W, do not support Qualcomm QC, I wonder what kind of adapter the two phones use. I used a 5v/3a USB C charger and USB C - C cable with my Nexus 6P. Does this adapter and cable work on Google Pixel/Pixel XL?

Absolutely, USB C is designed to negotiate with the charger how much juice is sent. the pixel works at 5V 3A (15W) and up to 9V 2A (18W), Basically if the plug fits it'll get some sort of charge. There are loads of USB C chargers with PD, the spec goes up to 100W and any charger will provide any device with the maximum it or the device can handle (So a 100W charger will give 18W to the pixel and the Pixels 18W charger will give 18W to a laptop for example)
If you have a true USB-C 5V/3A charger now, it will work fine, but as stated it is not the BEST option. 5V/3A = 15W.
If you buy a USB-PD (Power Delivery) type C charger, it has the capability to charge the Pixel at 9V/2A = 18W, so a 20% faster charge... in a perfect world, instead of 0-50% power in 30 minutes, you'd get 0-50% in 24 minutes. BUT, we don't know how long the phone will charge at 18W. Hopefully to 50%, but it has to cut down current eventually just like all QC chargers, or else it'd damage the battery.
The charger included in the box is USB-PD compliant.

My guess is no because that is relying on a QuickCharge handshake to occur between the device and charger. Pixels will use USB Power Delivery which is an entirely different specification. It'd be great if it does, but I highly doubt it.
It seems even the ones on Amazon that are PD units all are either 15w (5x3) or have the 9x2 spec but don't actually show it as addressable in handshake.
I just want to give someone my money and I am getting upset that I don't have anyone to give it to...
@bigblueshock It seems Tronsmart W2PTE not a 9v/2a PD charger, I saw Choetech has a 29w USB C PD charger

Great Phone, I am thinking to buy it.
uhh, QC3 supports both 5v3a and 9v2a. I use my QC3 charger with my Pixel C and it rapid charges.
The same will most likely be true for the pixel phones
I think it still doesn't work because the difference is in the protocol for handshake, not a limitation in the ranges of current.

Wouldn't it be nice if the phone could say what it was receiving and how it had negotiated? I've accumulated quite a few mains chargers, power banks and cigarette lighter adapters.
A QC2.0 PSU makes my Pixel XL say charging rapidly, but it doesn't say how rapid. Another mains charger said charging slowly, which was odd (you'd expect that from an unpowered USB hub) and others just say Charging.
How are you supposed to know what's what? The supplied PSU says Charging Rapidly, but clearly it's more rapid.
Even just putting it as an option in the developer menu would be good enough. It would then enable me to check all my various adapters and establish what does what.
Wouldn't it have been nice to just have one standard?!

There are special USB adapters that you plug between phone and charger that will tell you what it's using and what the voltage and amps are.

Hi everyone!
I have a car charger for my old phone, the OnePlus 3. But yesterday my Samsung Galaxy s8+ arrived and is now my daily driver .
My question is : Does a official OnePlus car charger (with dash charge) works for my Samsung Galaxy s8+? If so, does it damage the battery?
Kind Regards,
Pieter
I have tried mine with the old OnePlus dash charger and though it works, the charge speed is crazy slow. The phone was reporting that from about 40% it would take 5 hours to finish the charge.
Am guessing there is something propitiatory in the dash charger that is causing this. I dont use it on the S8 anymore, incase its damaging the battery somehow.

It won't damage the battery, but it also won't do fast charging as the Dash charging is proprietary and doesn't support Qualcomm's (also proprietary but much more widely used) Quick Charge 2 (or higher; QC is backwards compatible) that the S8/S8+ uses.
According to the car Dash Charger specs the standard (non-Dash) charge supports up to 5V at 2A, which is 10W. Compare this to the official Samsung charger's 9V at 1.67A (QC2), so provides 15W.

In theory then it should be able to charge the S8+ at two-thirds of the speed of the official charger, however it is possible there are other incompatibilities that slows it down - ie. the Dash charger won't provide the full 10W for some reason. A possibility might be the Dash charger cable, as from what I understand this is a bit different to a normal cable to support the Dash charging technology. Maybe try a high-quality standard USB and see if it charges any faster?
An aside: The S8/S8+ is the fact it can also fast charge over (the non-proprietary) USB Type C with 5V at 3A (also 15W). This isn't USB Power Delivery (USB-PD), just the 15W allowed by USB Type C, and since that can provide the full 15W the phone can use over QC2 there's no actual need for USB-PD - but most charges that support 5V at 3A are labelled as providing USB-PD and will work with the phone even if the phone don't use the 'PD' part of the spec.
I have a 45w usb-c travel charger for my laptop. While traveling, can I safely use this to charge my 5t?
I have poked around a bit and have not been able to get a firm answer from they. Can I do this?
You will definitely be able to charge it but it probably will be limited to 10/12 W. So no fast charging but at least charging
Check your charger to see the output spec. On my Dell 30W charger, it says 20V/12V/5V~1.5A/2A/2A. So it can be used to charge 5V devices, but not as fast as dash on 1+5t.
My charger has similar values. I tried it out and it worked! Thanks for the input!
Almost no point. Anyways most devices choose how much current they draw from a power source. just be wary that high voltage are dangerous (most of phones have circuit protection)
