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 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.

If it's "unsafe" then why would Google use in the Nexus line? If anything, all of the quick charge out of spec systems (like dash charge or quick charge) are "unsafe"

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.

Exactly.
So..........anyone know if it's Qualcomm Quick Charge 3.0 or something else? I found one report that claims it's QC3, but not sure of their source. Not sure if anyone saw any "hands on" videos where they were able to ask Google about it.
Mahalo
Don't know for sure, but I was curious and searched for info on the Qualcomm Snapdragon 821 that the Pixels use. The 821 does support quickcharge 3.0 so chances are the Pixels will use it.
https://www.qualcomm.com/products/snapdragon/processors/821
EDIT: Well reading this https://plus.google.com/+BensonLeung/posts/GnjQBqAovnD it looks like Qualcomm quickcharge is not used, but instead they use the USB-C fast charging standard. " I would really prefer if they had mentioned Power Delivery, instead of "Type-C quick charging" which could be misconstrued as Qualcomm's proprietary tech. The Pixels do not use proprietary technology to charge. They use standard USB Type-C and USB Power Delivery."
Tried to post last night, but couldn't. As mentioned above, it uses USB-PD, and not qc 3.0. Many argue USB-PD > QC 3.0.
When I use a Qualcomm QC3 charger with my Pixel C, it rapid charges. QC3 supports a 5v3a 15w charge, which is the Pixel C's USB PD requirement. As QC3 scales its voltage and amperage, it's likely QC3 chargers will support USB PD at 18w too.
(I havent gotten it working the other way around, for example, the USB PD charger rapid charging my HTC 10 that uses quick charge.)
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?
Will it work? Sure.
Is it the optimal option? No.
Thank you @testinguser. Can't wait to get the phone.

Umm... USB Type C will charge at 3A, no?
Shouldn't it be 5V/3A for the Pixel / Pixel XL also?

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.

Great info. Now I wonder if the Tronsmart W2PTE will charge at 9V/2A...
http://www.tronsmart.com/tronsmart-w2pte-type-c-quick-charger-3.0-dual-ports-rapid-wall-charger
USB C port output:3.6V-6.5V/3.0A,6.5V-9V/2.0A,9V-12V/1.5A(MAX)
USB A port outpout:5V/2.4A(MAX)
Technically it has the ability to, but I wonder if it can.

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

I may try this one
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.
I'm seeing unexplainable results, like faster charging from my old Motorola Nexus 6 Turbo Charger than with the included Pixel charger....

I can second this. Plugging it in to a QC3.0 type C charger (like the HTC 10 has) displays a "charging rapidly" notifier on the lockscreen.

But that doesn't actually MEAN anything. I had a bad car charger that would overheat easily over time. My Nexus 6P would say "charging rapidly" and Ampere would show 100mAh, charge completion time was over 3 hours, etc.
Google designed the phone for USB-PD, nothing else. QC 3.0 does work with this phone. Unless someone uses a USB power meter and posts solid numbers like mentioned in a previous post, people need to stop posting this ****.

I just purchased an LG G7 ThinQ on Verizon in the US, coming from an LG Optimus G Pro, purchased in 2013. It's being shipped right now, so I don't have it to play with.
With that said, I'm a newbie to quick charging. I see that the phone comes with a QC 3.0 block, and that the phone is listed as being QC 4.0 compatible, as per Qualcomm's website.
I'm looking to order all new cables and chargers to take advantage of the higher charging speeds that this phone can allow. I'm not understanding though whether I'd be better off buying a car charger that is QC 3.0 or has USB PD. I realize that the USB PD would be the way to go for laptops and larger items, but for our phone, is there any difference? I do realize that I'd need a dual-ended USB C cable for the PD charger.
Also, has anyone tried using a QC 4.0 charger on the phone, and although Qualcomm says the phone has the 4.0 hardware, has LG enabled us to use it?
So the LG chargers can deliver 9v 1.8A.
The phone will recognize my 18w and other 45w PD charger, but I haven't managed to see any difference in the charging speeds, and more annoying, charging is pretty slow when screen is on.
I wanna buy a USB meter (PD compatible) to see what's the phone actually asking for, but I assume that it just sits at 15w max.
The reason I have a PD charger is because it allows you to have longer USB-C cables and it's compatible across more devices, like I can fast charger my Huawei Mate 10 pro with it, you can also charge iPhones with it.

USB PD is an entirely different language than QC 2-4. They negotiate and handle power different from each other. If you plug USB PD into a QC device it should default to 5v, 1 or 2 amp standard charging.
Use only QC 3.0+ equipment. That will get you the rapid charge you're looking for as it speaks the right language for the phone. I dont believe LG has enabled QC4 standards in the firmware although the chip supports it.
LG G7 is also wireless rapid charge, i get an almost QC speed on a 15w ravpower and umdigi wireless pads. Took me a few to find ones that were quality and charged fast. Most of the "10w" chargers dont actually put out 10w so they dont charge fast.

QC 4.0 is actually compatible with Power Delivery, Qualcomm did that in fear that Google would make PD mandatory.
And there can be handshaking between previous QC devices and PD chargers, since the most basic profiles are kind of standard (max 9v 2A).
So in this way I can fast charge a S8, the LG G7 and any other QC device with the PD charger and I can charge other PD and QC devices with my Huawei fast charger power bank (it's based on QC 3 delivering max 9V 2A).

I just wished that phones would support higher charging rates via the PD standard.
I'm mostly sure that neither the S8 nor the G7 are taking full advantage of the max power output of their charger for long.
I thought that the charger might be under delivering, but connecting my PD 18w charger results in the same situation, I still need to measure it (need to buy a USB meter to have more details).
But using the same 18w PD charger I can charge the Mate from 20 to 50% much faster than I can charge the G7.
