Is it possible to enable 15W USB-C fast charging? (5V/3A)

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.

Google Pixel/Pixel XL Use USB Power Delivery up to 18W, do not support Qualcomm QC

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

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 ****.

OnePlus car charger

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.

G5 charging slow on 99% of cables

Hey!
I noticed recently that my G5 charges quite slow. So I tested all of my powerbanks, cables, and wall chargers, in various combinations. I had 4 different powerbanks, 3 wall chargers, and 4 cables.
I used a USB ammeter to measure the power draw going through the USB cable.
On the motorola charger and cable that came with the phone, it charges at 1.8a. I then charged my phone from each powerbank and wall charger, using each cable in turn. The average charge speed for my phone was about 0.5a. Out of 28 combinations, only 2 yielded a draw over 1a.
I have created a spreadsheet detailing the charge speeds of each combination, but unfortunately cannot post it yet (10 post permissions).
I then charged my USB powerbanks from the same wall chargers, using the same cables. One powerbank charged at over 1a with every combination, and reached over 2a on numerous combinations. This proves that the cables and wall chargers are not at fault, it is a phone issue.
Why? Has motorola put something in their chargers that 'talks' to the phone, and allows for faster charge speeds? 0.5a is awful!
Secondly, does anyone know of cables that I can buy, which will support fast charging for the motorola? I have looked at genuine motorola cables, but there is no way to tell one from the other.
Thanks!
Paul
P.s. charge speeds were the same, whether the phone was switched on or off.

Welcome @agour
I've come up to a similar conclusion with a lot less data (thus I didn't share them).
I caught power consumption at the wall outlet when charging my device with two chargers: Motorola stock charger and a Samsung Adaptive Fast Charger.
The Samsung has the following specs: 5V 2A or 9V 1.67A with fastcharging capable device.
Using Samsung Adaptive fast charger and Samsung 1.5m cable : 6W, so the device charges at something like 5V 1.2A...
Using Samsung Adaptive fast charger and the cable provided with my XT1676 : 11.3W (which is coherent with the max 9V 1.6A, and would mean the charger provides 2.2A if at 5V which more than the specs.)
Using stock charger and stock supplied cable : 11.3W ==> fast charge for similar reasons as above
Using stock charger and Samsung 1.5m cable : around 6W ==> low power charge
I'd need a USB multimeter to confirm those data. (mostly due to the variable voltage that can provide fast charge adatpers)

Interesting! It's suprising how much difference the combinations can make.
I don't think I have experienced this on a phone before, however I have never felt the need to test it...
I tested the original cable that came with the phone, and an off the shelf 'genuine motorola cable'. The stock cable is still the fastest, however the secondary cable still worked very well.
Interestingly, one of my powerbanks will charge at 2.2a from pretty much EVERY powersource and cable combination. This is with 7 cables tested, and 3 USB wall adapters.
Shame that motorola doesn't allow their phones to draw maximum power from hardware that can provide it..

If I have some time, I may test internal impedance of the cables, it is possible that the device somehow probes the cable (or the cable + charger) and then decides if it can or not draw that much power without overheating/melting the cable; and then it will negotiate the quickCharge with the charger.
there has been a discussion about quick charge on this thread a while ago (before I got this devices : https://forum.xda-developers.com/g5/help/quick-charge-3-0-support-t3632457)
Lenovo adds the following that I have not tested:

It is quite obvious that especially cheap cables will charge phones much slower as the resistance is too high, even if the phone does not perform any checks. Those cables are basically too thin. Resistance limits the current (amps) that can flow. Newer phones most likely just look at the charge current during the first x seconds (or less) and then decide wether to enable fast charging or not to keep the cable from heating up. A wire with high resistance is basically a heater. So it's a necessary safety feature (from the companies POV).
Regarding the power bank, it may be possible that this particular design provides a voltage slightly higher than the nominal 5 volts (still fine for most devices), which helps overcome the resistance. That is also the reason why the Samsung fast charger provides 9V: You don't need a cable as thick as with 5V.
Keep in mind that the USB specifications only recently got updated for such high charging currents, so it is advisable to use only the cable that comes with the phone as USB cables in general don't need to provide such high currents by spec!

That sounds correct, although my Samsung wall adapter is fast charge capable, and was provided with a cable (and not a cheap one), that basically can't be use for fast charging with the G5, that looks silly...

Question Obscenely long time to charge

Not sure what's going on here but just plugged my P6P in and after about twenty minutes of doing something else I checked it and started laughing. Also the net standby stuff is at 33%. Is all this because of this months patch because it's charged better than this last month. Anyone else have this problem and how did you fix it? Thanks in advance for any help.

I had a problem charging my phone for the past 3 months. Finally upgraded to a new GaN3 charger and it solved all my charging headaches and future proofs me for a few days. I have these fancy magnetic adapters I bought too which really add to the experience.

There's the links for you all. Has worked with everything I have put on it so far. Pixel buds, samsung watch, S21 Ultra, Pixel 6 Pro charges FAST with no heat.

I doubt if it's the latest firmware - at least by itself. My wife and I haven't had any problems charging our phones from multiple sources/different cables.
You could try turning "Adaptive Charging" off and see if it helps, although I still have mine (and "Adaptive Battery") on.

Thank you guys for the help. I actually turned everything that has to do with the word "adaptive" off so I'll test it over the next few days. Woke up to my phone only 85% charged on my wireless charger/lamp which sucks. I just wish Google didn't set so many restrictions on what can charge the phone at it's fastest and keep it there.

My P6P and my wifes Pixel 6 charge faster than that and we use one of THESE to make it as slow as we can overnight (with adaptive charging) so i dont think it is anything to do with the recent patch.

Turning off Adaptive Charging and using a nice PPS charger and cable will alleviate most of the charging complaints for the Pixel 6. Those old USB-A or regular PD chargers won't cut it.

I also recently experienced the same issue as the poster, and honestly idk what it could be other than an individual defective phone or a bad update. First noticed the issues about a week or two ago for me; although don't have an exact date. It doesn't happen 100% of the time, but it does frequently occur about 90%
At LOW battery, I'd be getting 9w draw (read on an external USB C charge-reader). Accubattery and ampere, while less accurate, also read 930MaH charge. Google stating 4.5 hours till full charge. Despite my phone stating its being "charged rapidly"
Contrasting that to what I consider "normal" at 18w-23w draw on the charge-reader, or 3600 - 4600 MaH with accubattery and ampere
Same charge speed on all bricks I used. Tried different outlets, cables, even my car:
* Google charger
* ANKER 30w PD
* ANKER 65w PD PPS (brand new)
* FasGear 30w PD AC (car)
* Used 4 different USB-C to C cables: one by Google, two by Anker, one by UGreen.
* same charging speed from 1% through 50% (which is supposed to be when it charges the fastest)
* temperature was normal
* technically only "adaptive charging" is relavent (which was off), however for ****s and giggles I turned anything adaptive off.
Beyond the testing I did above, I checked accubattery's history and saw several days (where I charged from sub10% to 100%) report the maximum off-screen charge was still below 1000MaH throughout the entire charge session

It sounds like something might be physically broken at your end. I'd suggest to contact Google. They will want you to go through a couple steps (probably factory resetting the phone, changing cable and power brick), after that they will probably offer you a replacement/repair the phone.

Indeed. I wonder if there could be something physically or electronically borked with the USB-C port/connection on the phone itself.

Be careful with USB-C, it easily captures dust that is pushed in the back of the slot when you plug the cable, and after a while it prevents the cable to be fully inserted, creating connection issues.

Anker Powerline III cables don't fully support PPS. Charging would disable and enabled, in an apparently random way. Anker's 10ft usb c to c cable works fine though. So extraordinarily thin cables like the powerline 3 probably provide less than ideal charging speed.

So even though I have the power line 3 flow anker 6ft cable and their 65 watt nano 2 charger I'm not getting the fastest speeds? The cable is rated at 100 watts so I thought I was eliminating charging bottlenecks.

This is the product I'm referring too.
USB Power Delivery is much more powerful, supporting up to 100W of power to charge up even the most demanding gadgets such as laptops. It’s also safer, as gadgets and chargers communicate with each other over the USB cable to confirm the optimal charging power level. This handshaking approach supports voltage steps at 5V, 9V, 15V, and 20V for power outputs ranging from 0.5W to 100W. The new USB Power Delivery Programmable Power Supply (USB PD PPS) standard supports configurable voltages too, enabling more optimal charging. If two devices fail to communicate a suitable power rule, USB Power Delivery will default to the next power option supported by the relevant USB protocol, such as USB-C 1.5A
PPS itself does not enable 100w charging. USB PD 3.0 does. So that wattage bottleneck you're referring to doesn't matter since PPS is another charging standard built intop of USB PD 3.0
So what I was saying is that an extraordinarily thin cable like the Anker Powerline 3 may not be ideal when using a PPS charger. Works fine with USB PD 3.0

So what I'm getting at right now is that my 100 watt flow cable is actually charging slower with my wall charger then the one you linked?

Are you using a Powerline 3 cable and a PPS charger if so? It may perform sub optimally, in my experiences.
