USB 3.0 Charging Advantages

So I've read an article that mentioned USB 3.0 Micro-B faster charging capabilities, does anyone know any validity to this?
I know it increases transfer speeds, but I was unaware if it actually charged faster too.
And if it's true, does anyone have any car charger recommendations to support this feature?
I saw this, let me know what your thoughts are: http://www.belkin.com/us/p/P-F8M864/

Why pay $30 when you can get the same (or ever better) results with a good usb 3.0 cable and a 2.1 or Anker's 4.8A usb car charger for less?

It's true that USB 3.0 allows for higher current but this only applies when you're connecting a USB3.0 device to a USB 3.0 host like a PC. A charger isn't a host device, they work by shorting data pins. So chargers don't follow USB specifications at all.
Your limitation here is voltage and amperage. Because chargers generally work by shorting the data pins your phone will draw as much power as it can handle and as long as there are no limitations on your charger. So it's not likely that you will be able to max out a 4.8amp charger, actually it's not likely you'll be able to max out a 2.1 amp charger either.

I find it interesting that the stock Samsung charger is NOT a USB3.0 charger. If you look at the USB port on the charger, it doesn't have the 3.0 pins...

USB 3.0 cable DOES come with some S5's

Some people seem to have not been given a USB 3.0 charger, but others have reported that one was included.
I was given a 3.0 cable with mine in the box. It is a white cable and is labeled "Samsung" on the plug.
FWIW, the new 3.0 plkug seems to hold more tightly than the micro-B 2.0 plugs in previous phones.

Maybe I missed something, were there some people that got 2 seperate cords or just the one white, Samsung labeled cord?

Then what's the best charger to get for DC plug that you would recommend? Just look for something with the highest amps?

Just the cord

I was only given the one cord. Also, I don't believe that I got a charging block.

Only received a USB 2 standard lead with mine.

USB 3.0 standart is meant for PCs/Macs/Devices. Original USB 2.0 port on PC would output only 0.5A. Default wall chargers would output 1A. Car chargers are different, but my 2A charger didnt charge my old phone any faster.
With USB 3.0, PCs should give out 2A (if Im correct) meaning u will charge 4x faster on USB 3.0 port.
With wallchargers its different. Cable itself doesnt have the limit (atleast not noticable one), meaning on 2A wall charger, and stock USB 2.0 cable, which comes with galaxy S5, you should charge with 2A.
Each device have power protection aswell, thats why older phones can use max to 1A to protect itself, while tablets needed 2A charger. I suspect galaxy S5 is made to charge with 2A aswell, aswell it holds up backward compability with 1A.

Thats correct...I think i heard on AC that the International S5 didnt get the 3.0 cable, but i could be mistaken. Us on Sprint got the White 3.0 cable and it charges Super fast....I love the newer cable, so much more convinient

Try TYLT chargers.

I got the white USB 3.0 cable with mine, and it definitely charges much faster than my s3 did even on a 2.1A charger.

I bought a USB 3.0 cable from ebay, it is a surprisingly fat cable, the same thickness as an ethernet cable. Couldn't believe how fast it charged compared to my S3.
http://www.ebay.co.uk/itm/321347128...eName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
I plug this into the wall charger to charge the S5 instead of the tiny thin cable that I had from an old phone. I haven't done any proper testing on this but the old small cable seemed to take about twice as long to charge the phone as using this cable does. I can go from 15% to full on this cable in probably a bit over an hour or so and it seemed to be taking at least double that with the other non-usb 3.0 cable.
Perhaps the other cable is providing less power as it is quite old but is still standard usb to micro usb so I guess it provides the same as any other and in theory should charge exactly the same when plugged into the wall socket adaptor as the usb3.0 cable does? The old black micro usb cable says 28AWG on it, the white one which came with the S5 (which I have not tried) says 30AWG on it and I read that lower AWG is better for charging which implies the white one will be even worse than the old black one. The USB3.0 doesnt show an AWG number on it.
The only problem with this usb 3.0 cable is it needs a damn hard pull to get it out, I would rather use the smaller one but not if it takes much longer to charge it.

USB3.0 on PC outputs only 0.9A.

From wiki:
For usb 3.0
"there is a Battery Charging Specification (Version 1.2 – December 2010), which increases the power handling capability to 1.5 A but does not allow concurrent data transmission.[20] The Battery Charging Specification requires that the physical ports themselves be capable of handling 5 A of current[citation needed] but the specification limits the maximum current drawn to 1.5 A."
For usb 3.1
"The USB 3.1 standard is backward compatible with USB 3.0 and USB 2.0. Using three power profiles of those defined in the USB Power Delivery Specification, it lets devices with larger energy demands request higher currents and supply voltages from compliant hosts – up to 2 A at 5 V (for a power consumption of up to 10 W)"
Now it is all very confusing because I read on techspot that "usb 3.0 superspeed" effectively has this increase, where wiki says there is no such thing and that this "superspeed" is 3.1 not 3.0.
None of them mention 0.9a. So it is as clear as mud. The official plain old usb 3.0 will only do 1.5a and thats if there is no data connection, and either usb 3.0 superspeed, or usb 3.1 will do 2a but I have no idea whether it is called usb 3.1 or "usb 3.0 superspeed" which would be ridiculous and confuse just about every consumer on the planet. I doubt it is called 3.1 because I have never heard 3.1 mentioned before on any device or cable, which leads me to think the extra charging in the newer revision is actuall the "usb 3.0 superspeed" which basically means nobody has a bluddy clue because most things will simply say usb 3.0. there, clear as mud.

Electrical
Signal 5 volt DC
Max. voltage 5.00±0.25 V (pre-3.0); 5.00+0.25-0.55 V (USB 3.0)
Max. current 0.5–0.9 A (general);
5 A (charging devices)
The thing is that when you plug your phone on your computer, you use data transmission, so you're limited to 0.9A

So we get 2a from wall socket regardless of which usb cable used. And when connected to pc we get 0.5a from usb 2 and 0.9 from usb 3?
How long should the 2800mah battery take to charge from 2a from the wall socket from 0 to 100%? I worked out 2 hours 20 mins but I probably did it wrong. I just tested mine from 50% to 100% on the wall socket and it took 1 hour 15mins which seems about right for my 2h 20 calculation, but I could have sworn I had charged this thing from about 15% to full in a bit over an hour before, but I may be going mad.

I received a 2.0 amp samsung charger + 5 feet USB 3.0 cable out of the box
bought from at&t in store.
International S5 only receive the USB 2.0 cord

No, Google sells Type-C to Type-C ones but its out of stock right now

I'm fairly certain Apple's USB-C charger will work fine, but it's $49 without a cable.
Google's offering is cheaper, has two ports, plus a cable so I'd wait for that.

You want a charger compatible with Qualcomm Quick Charge 2.0 for the 6P. Quick charge allows charging at 5V, 9V and 12V. The charger will supply the voltage/amperage appropriate for the current charge level of the battery. Most older phone chargers are 5V and will work, but will not quick charge the phone. You can, however, us a Type C to Type C cable and charge your phone from a MacBook Pro Type C connector.

That's a misnomer for the QC2.0 stuff. The usb-c to usb-c charger is automatically going to work with 5v/3a charging without the need for QC enabled functionality. Actually, there is some debate as to whether or not QC2.0 will even work with this phone if you have a standard usb-a to usb-c connector on a QC2.0 usb-a port.

Yes, the Type C to Type C has nothing to do with QuickCharge. It is a USB standard.
However, QC 2.0 works now on dozens of phones with Type A to Type B (Micro USB 2.0) connectors. If you connect it to a PC USB 2.0 connector, you will only get 5V! In fact, I suspect that even my USB 3.0 ports on my Gigabyte P5-USB3 motherboard also only supplies 5V. You must have a charger port set up to supply the higher voltages. If you look at the Wall/Car chargers that are QC2.0 compliant they usually have 1 QC2.0 slot and 1 or more standard slots that will only supply 5V.
Interesting point is the iPhone 6s actually has Qualcom QC 2.0 built in, but not utilized by Apple. The supplied charger with 6s is underpowered and a 6s can be charged much more quickly with a higher amp charger like that for an iPad or Kindle Fire.

My Zenfone 2 had QC2 with an intel chip but ASUS called it quick charge with their 'boostmaster' charger but in reality it was just QC 2.0. Samsung calls it adaptive fast charging but its still QC2 etc....the Nexus likely doesn't support QC 2 because it requires a license as another member mentioned which would add to the overall cost

Not sure what you think is misleading, but let me try to clarify:
1. If you have a QC2.0 compliant charger and a QC2.0 compliant device, then QC2.0 will work regardless of the type of connector on the ends of the cable.
2. iPhone 6s has the capability for QC 2.0 built in, but can not do it because it is not utilized. However, you can provide higher amperage to the device at the same voltage than what the standard 6s charger supplies and hence, it will charge faster (not QC 2.0 though).

Understood, but there are plenty of threads debating what the actual volts/amps will be on the phone if you use A-to-C with QC2.0 chargers. According to the spec it is 15W (9V/1.8A or 5V/3A), correct?

It will get the voltage/amps determined by the charger. The 6P is not QC 2.0 CERTIFIED. Google didn't go for the pretty sticker.
From the QC 2.0 FAQ:
Q6: Does it matter what type of charging cable is used with a Quick Charge 2.0 adapter?
A: Quick Charge 2.0 is designed to be connector-independent. Quick Charge 2.0 can be implemented with a variety of formats, including USB Type-A, USB micro, USB Type-C, and other proprietary connectors.
Quick Charge 2.0 high-voltage operation is designed to minimize charging issues associated with long or thin cables, allowing for a superior charging experience, independent of cable type.

You're arguing this in two different threads with multiple people trying to educate you on the power PIC controller interface. The chipset can handle the charging, but the actual usb power interface controller won't pass along those signals. It's not like applying a wire and getting charge -- there is a handshake that happens for the correct charging current and voltage to be applied.

Gotcha. The phone will identify the voltage requirement and the charger (assuming intelligent) will supply that voltage at it's rated amps. Actually, the default for all USB is 5V. If the charger does not get the handshake it will default to 5V. So a 5V/3A charger that is capable of multiple voltages will only supply 5V to such a device. Which is what the Google charger supplies. Most chargers will default to 5V and less than 3A however.
I will be interested in testing the Google charger and phone when I get it in my hands. The problem with charging is the change in resistance as the battery charges which is the point in multiple voltages. I like the new USB-Power Delivery setup, but there will be teething problem for early adoption.

None of them will. You might get close to 2 amps if you are lucky, but no Type-A port will support Type-C fast charging. While cable quality matters, its more dependant on the load the phone can draw from the charger.
See: http://forum.xda-developers.com/showpost.php?p=63220997&postcount=1

Continuing off what Elnrik said, you can still go ahead and buy yourself some generic quality USB A to USB C cables (see one plus cables for quality and value). You'll get pretty standard old charge rates through them but they are better than nothing in a pinch, for the time being, unless you want to replace all your old adapters.

With the Nexus 6P, none of them. It is not the cable, but the 6P that is the culprit. All those cables will actually support 5V/3A. For some bizarre reason, Google designed the charging system in the 6P around the Type C spec (the spec for a connector) and not around the USB Power Delivery Spec, but then used the configuration channel in USB Type C which eliminates the possibility of using Type A to Type C for putting 5V/3A into the 6P. Even Apple respects USB Power Delivery in the MacBook Pro.
I think Google's mistake (or at least foolish decision) will become apparent next year when the next Nexus phones (and a lot of other laptops, tablets and phones) have Type C, but not 5V/3A and instead support more standard power like 5V/2A and 12V/1.5A. There is a reason Qualcom chose those 2 combinations for Quick Charge 2.0. They didn't pull them out of their butt like Google.
To me, not having the device in my hands, is the biggest single disappointment with the phone. Don't get me wrong, even 5V/1.5A is decent power for charging a phone. Guess the other disappointment also centers around the implementation of Type C and not allowing HDMI via the Type C connector which it was expressly designed to do.

Don't confuse the cable's capability to handle 3A with what the SPEC allows. A Type A to Type C cable can actually handle 3A. Both connectors can do it. Even a Micro B can do 3A. The Spec does not support it. And here is the big issue. The spec, both original and the newer ones including USB-PD are set up for simultaneous power and data. For a charger, we are only worried with power and data speed/corruption is not an issue.
USB PD allows 60W (20V/3A) through micro B and100W (20V/5A) through standard A and B. It requires specially 'marked' cables which will be a little beefier than standard 2.0 cables. But the connectors can handle it.

So what is the solution?
Get new car and wall chargers only usb type c cables?

Okay, this is interesting. So, if the cable and both the A and C connectors can both handle 5/3, could you plug this cable into a block that pushes out 5/3 via a female A port and achieve maximum charge velocity?
That goes against what so many have said - that you need C to C - but I'd be delighted to hear it.

EDIT: Just saw @dwswager's post. What he said.
-------
TLDR:
USB TYPE-A has standards not specs, limitations are grounded in physics not words and it is possible for a USB type A to deliver 3A with lower Ohms at 5v with the right power adapter/hub.
USB 2.0 refers to Data rates not charge rates.
Bonus: 3A 5V is one of the Quick Charge Class A power standards for C to C even if 6P isnt yet certified for it. Could be Google pushing for an A to C 3A to 5V Quick Charge USB Class?

I really don't know what Google are playing at with the spec for that cable. There's no way in the world a USB Type-A 2.0 cable can deliver 3A. You absolutely need Type-C end to end to achieve that.
If I'm wrong, I'm gonna look like a right chump. But I haven't been ravenously soaking up info on this topic for nothing!

I think the conversation over USB "specs" has been misconstrued. What people are looking at are USB standards. Standards are not limits. They are heavily optimized guidelines for creating compatibility and uniformity with as many devices as possible and to protect as many devices as possible from accidental burnout.
USB 2.0 Data rate does not prevent a USB A port from having a 3.1 or similar charging configuration.
As is already clear, Google is not following USB charging standards of any kind with the 6P and noted by @dwswager.
It is entirely possibly to throw 3a INTO a USB A standard cable; ampere limitation isnt the problem USB 3.1 standards for USB A do it perfectly fine but at 3a 12v(4ohm), which is a higher ohm set up than with 3a 5v(1.67ohm). We also know that USB 3.1 standards allow for 2a 5v (2.5ohm), which is even closer to the 3a 5v set up. .The standards are set at those points because the lower the ohms the great the heat created, think of it like a welder, or a sub-ohm vaporizer.
Note that the size of the USB 3.1 pin size don't change due to the change in ohms. What is likely changing is the conducting material and size of the transmission wire.
Most 2a 5v cables run cool because the cable is a 2.5ohm resistance cable and its getting fed precisely 2a, as very carefully designed, which then makes that cable a "5v" (2.5ohm x 2a) cable. A 3a 5v cable would hence need to have a lower resistance of 1.67ohm, which is higher conduction, likely from a more optimized conduit throughout.
The cable can exist under Huawei/ Google's unique of standard setup.
Thing is, nobody as part of the USB standards have ever said you CANNOT put 3a through a USB Type A, but also nobody outside of chinese ebay sales sell anything with USB A that puts out 3a at 5v right now (Google for it, they exist. Wouldn't recommend buying one).
Bonus from Google CS (Source: http://www.droid-life.com/2015/10/19/nexus-6p-nexus-5x-quick-charge/#comment-2315607310):
"Currently, the Nexus 6P isn't listed on Qualcomm's list of devices
that have been tested and certified to be compatible with Qualcomm Quick Charge
2.0 chargers, so I can't say with 100% certainty yet. This is something that can
change the longer the Nexus 6P is out on the market and is tested for
compatibility and interoperability."

I have been fighting this corner since the day of the announcement, I am glad to hear someone else say it. There is absolutely nothing about USB Type-C that has any effect on wall chargers and the amount of current it can draw, and equally nothing stopping Type-A from providing aforementioned current / voltage. What it needs its a cable that can handle it (like the offical Google one), and a wall charger that will provide it, simple as that.

Thank God! Realism
If under USB-PD Profile 5, Type A can handle 20V/5A, why people think it can't handle 5V/3A is a mystery. The question has been will the phone accept it with an undetectable (to the Type C device) Type A to Type C cable by the 6P. The answer appears to be yes it can.

I've bought the cable I linked to from Google (it has already turned up) and I have bought a car charger that claims to output 3A/5V so I will be testing as soon as my device turns up. The car charger wasn't cheap, but it has been rebranded a lot so it's 50/50 as to whether or not it will hold up to it's claim. It has a type-C port as well so I can at least check they output the same.

@vido.ardes @dwswager. If what I quoted earlier from G CS is correct and the Nexus 6P hopefully-perhaps-maybe gets certified by Qualcomm for Quick Charge, and google updates the kernel to enable it then we'll have the entire world of Qualcomm certified 3A Quick Chargers at our disposal. Its a hope.

Not sure how it would get certified. QC 2.0 takes an extra chip in the device and the 810 SOC is not QC3.0 certified.

That's interesting!
All this charging crap could have been avoided if Google would have just spent 30 seconds explaining it. I suspect that they used Type C and designed the circuit to take 3A and wanted to call that fast charging without having to actually implement a fast charging solution.
If I had the 6P in my hands I would get a few chargers:
Google Captive (5V/3A)
A Type C 5V/3A
A Type A 5V/3A (or the ASUS Transformer charger with micro B and a micro B to C adapter.
A 5V/1A charger.
Then with phone less than 10% charged plug them in and check the current draw. All of them should be somewhere close to the Nominal rated current output.
Then with the phone above 90% charged, plug them up again and they all should be drawing about the same current because the current draw should be well below the rated current of all the chargers.

Any way for USB-C charger and CC cable to get approved?

I'm looking for a USB-C plug for my Nexus 6P. There are so few on the market and I would like to try one.
http://www.amazon.com/Charging-Qualcomm-Certified-Supported-included/dp/B017I7EX46/
Anybody tried this charger and cc cable? Reviews say it works pretty well, but is there any tool like CheckR to test and approve the usb-c plug and cable? This might be important to note, due to the whole fiasco with the cables which would damage the phone/charger due to incorrect build. Benson Leung only tests AC cables as far as I know.

While there is the potential for a USB C charger and cable to not be powerful enough to meet the 3amp charging spec, a type C to C cable is unlikely to fail to be compliant in the same way as the A to C cables are.
The A to C cables were mostly non compliant as they were being identified as being compatible with the USB C spec and thus being able to supply 3amps of power, whereas in reality cables/chargers with type A connectors max out at 2.4 amps or in most cases a lot less.

A-C cables required a 56K resistor, but most companies initially used a 10K one which was the issue. C-C cables don't need a resistor the way that the A-C ones do,so they should all be compliant from what I understand.

I have been looking at the end chotech charger on amazon for 2 days now trying to figure out if it's OK or not since it's not on the Benson list of approved chargers.
Are you saying that if you get a charger like the one in the original posters link that has a USB c port you'll be fine because there is no USB A cable in the equation?

It should be fine as long as it only supports 5V/3(like the Choetech does) and not a different quick charging method like QC 2.0/3.0.

Even if it supports Qualcomm's QuickCharge, isn't part of the QC spec that there's a chip inside the charger to identify QC-capable devices and otherwise act as a 'normal' charger?
I would think so long as it supports 5V/3A you would be fine no matter what other standard it supports.

Here's a link to a google doc that details cables and charges that have been tested. It says if the item is compliant or not.

I don't see an issue, but keep in mine that longer cables could have a current drop due to increased resistance over the length. It shouldn't be a huge amount so I wouldn't worry about it. I use the Google 6ft C-C cable and get the full 3A when my battery is below 40%.

That's correct, but I don't want to fully recommend something that could cause an issue. I have a charger with QC 3.0 over the Type-C port and I have 0 issues using it. It still violates the USB standard to have QC 2.0/3.0 over a Type-C port, but that doesn't mean it won't work. It works, but could potentially cause an issue at some point. I can link you the post by Benson Leung along with the appropriate USB standard if you need it.

Still waiting to receive mine. Obviously it's not up to spec because of the type-c + QC 3.0 standard on the same port but hopefully it works fine. And I also really want that extra type A port and foldable pins. I'm also thinking of getting a Robin when it comes out which uses type-C but with QC 2.0.

I haven't tested that charger, but I do have the exact same model with 2 Type-A ports instead of 1 A and 1 C. Maybe Tronsmart will send me one to test out You can see a review of the version I have in my signature (last link that's says Tronsmart Titan). I have their car charger which also has the same voltages over the Type-C port and it charges my 6P just fine even though its technically not in spec.

Yeah saw that when you first posted it. I've had other Tronsmart chargers and cables before. I also bought the Titan when it first came out too and they haven't failed or anything yet. I'm just a little cautious since type-C is new. Hopefully Tronsmart sends you the wall charger to test. I won't get mine for a few weeks due to international shipping and everything.

I've got the Choetech C to C charger and cable. Would recommend it without any hesitation. Build quality is on par with the stock charger, but nothing more. It's not braided or anything, so it's a normal cable with a normal charger

I guess we will see what happens. The Titan is a beast, but I can't use the full potential is has with 2 phones. The wall charger should work fine if it's anything like their car charger.

USB Type-C VS MicroUSB

So it seems there are a lot of contradicting reports on the web right now. Some claim the s7 lineup will retain microusb charging while others say usb type-c will be used. Is anyone else going to be extremely bummed if usb type-c isn't used? I sure will be.
I was looking forward to faster charge rates, and a reversible cable. Might start eying the LG G5.

I can tell you with absolute certainty it's micro-USB, not type C.

If it's not a full (or at least USB 3.0) implementation of what USB-C is capable of, just same old USB 2.0 we've always had, I think microUSB is the better solution. We can keep using our existing cables. I would have loved a full-blown USB-C, but I can live without it.

Seeing as there are some reversible micro usb cables on the market, I guess in that aspect it won't be the end of the world. I was just hoping for some future proof, y'know? Using USB3.0 would of been great.

I wouldn't expect anything from Samsung to use USB-C until next year. They learned their lesson from the S5, and that is physically compatible with standard micro-USB.

I think there is no huge difference between both of them. USB Type-C connector doesn't mean that it will charge faster at the speed of light .

Admittedly, some of the Micro-USB-based fast-charging protocols are pretty close. Charging is faster because many chargers allow for a 15W (over 5 or 10 watt) charger, not inherently because it's USB-C.
USB C is pretty nice so far (Just got a 5X )
