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

Hi all.
There has been a lot of confusion on the Type-C port on the Nexus devices, all of the different USB specs, how it all relates to charging using USB Type-C devices, and what kind of data speeds you can get from Type-C devices. I did a fair bit of fact finding, and thought I'd consolidate everything I learned into one topic. For now, this is kind of a "living document" in that I am constantly updating the OP to consolidate knowledge. I'm not going to post everything you could ever know about USB specs here, but have provided the links! I am going to try to keep it focused on items as they relate to the new Nexus phones. As always, if you find this helpful, I'd appreciate the thanks.
I feel the state of USB-C cables and charging devices has been fleshed out well enough, and as such, I'm no longer updating this thread.
News:
Good news for consumers! Amazon bans non-compliant USB Type-C cables.

What rate will my Nexus charge at with other devices?
___________________________________
When you connect your Nexus to a host, the devices must negotiate which charging rates can be used.
Type C hosts can negotiate with Type C devices using a specific wire in the cable known as the Configuration Channel - aka, the CC wire.
If you are using a Type-A adaptor or cable, the cable must identify itself as a Legacy USB connection (Type-C being converted to Type-A) using a pull-up resistor on the CC wire, grounded to the vBus wire. This is because the CC pin does not exist on Type-A ports. The Nexus will see the resistor, know it is on a legacy port, and it will then perform power negotiation using the USB BC2.1 protocol on the USB 2.0 wires in the cable. If the host is not BC2.1 capable, it will draw default USB current. (See page 149, table 4-12 for order of precedence.)
USB Type-C ports and chargers will provide 5V at 3A (15W) - true fast charging.
USB Type-A ports and chargers using USB BC2.1 should provide a max of 5V at 1.5A (7.5W).
Standard USB 3.0 can provide 5V @ 0.9A (4.5W)
USB 2.0 defaults to 5V @ 0.5A (2.5W).
What this means is that when your phone negotiates power with the host (your charger or computer), whatever current level they mutually agree upon is what your phone will attempt to draw. If you connect to a USB 2.0 port on your computer, a very old port which does not support the BC 2.1 protocol, then the most you'll be drawing is 0.5A. If you connect to a dedicated charging device which supports BC 2.1, it should draw up to 1.5A. Charging rates depend on this negotiation. Out of specification cables do not allow this negotiation to occur correctly. This may lead to faster charging, but you also risk exceeding the capabilities of your charger which may be dangerous.
As you can see, there is a big difference between 15 watts for Type-C fast charging and 2.5 watts for USB 2. Furthermore, please be aware that the phone will pull less current as the battery charges. A Nexus at 80% battery will pull less current than a Nexus at 20% battery.
In any regard, consider USB Type A to be the weak link in charging your Nexus.

What charger and cable will work with my new Nexus, and will it support fast charging?
___________________________________
My suggestion would be to make the move to Type-C car and wall chargers. You will eliminate the chance of using out of specification Type-A cables, and ensure you are always fast charging. Type-C will soon be the de facto interface for USB, so why not future proof yourself now.
If you have to use Type-A adaptors and cables, understand that there will be limitations and concerns to be aware of. Out of specification cables being the primary issue, which is explained below. Further, your charging rates will be half (or less) than what Type-C is capable of.
Table 2-1 shows all supported power specs for Type-C charging. Please understand that Type-A ports/cables will only support up to the BC 2.1 charging level of 1.5A. If it goes beyond this, your cable may not be compliant with USB specifications.
Hi. I'm an engineer at Google who has worked on USB Type-C on the Pixel and Nexus projects.
The reason that the Google chargers and cables are capable of 5V 3A support is because not only the cables but the port on the other end is certified for the higher 3A ceiling. You will notice that the cable that came with your Nexus 5X or 6P has USB Type C on both ends.
This ensures that not only the cable, but the connectors and the charging circuitry on the other side of the cable can support 3A before the phone starts to charge.
When you have a legacy cable like this one, the connector on the other side is a USB Type-A connector, which can be plugged into any USB port built since 1997, for example your ancient Pentium II PC may have a USB port that this cable could be plugged into.
NONE of those USB Type-A ports are rated to support 3A, so many of the USB Type-A to Type-C cables available on Amazon that claim they are rated at 3A and configure the identifier resistor to tell the phone to charge at 3A are not in compliance and could do damage to your charger, hub, or PC if you try to charge at 3A.
When you have a legacy cable like this, 2.4A, which is negotiated over a BC1.2 protocol like CDP or DCP, is appropriate over the Type-A connector. Any cable that you buy that claims 3A support I would be extremely wary of plugging into any of your hubs, PCs, or dedicated chargers.
Click to expand...
Click to collapse
By the way, the maximum current of 1.5A is defined by the BC1.2 specification for CDP and DCP, but in practice, a range of other current values are possible using Apple's proprietary protocol or other protocols that bump up the defacto maximum current with a Type A connector on one end up to 2.4A, as long as the charger and the device both support that current limit.
However, keep in mind that there are 3 different termination possibilities. If you have the USB Type-C Specification 1.1, take a look at section 4.11.1, and at Table 4-13.
You'll notice that DFP Advertisement lists "Default USB Power" "1.5A @ 5V" and "3.0A @ 5V". It's important to read note 1. If you are making a legacy USB cable that has Type-C plug on one end, and a Type A plug on the other or a Type-B receptacle, you must use the "Default USB Power" termination, and NOT the "1.5A" one. Default USB power defers to BC 1.2 spec for current negotiation, so that such a cable that is attached to a basic 500mA SDP port should only draw 500mA, for example. Make sure to use a 56 kΩ pullup!

As referenced in the quote, Table 4-13:
What about QuickCharge 2.0/3.0 chargers!? My Nexus has a Qualcomm chip, isn't it compatible?
___________________________________
No. Google has stated that it is not implemented in the new Nexus devices.
QuickCharge works by increasing voltage and amperage to charge quickly. The USB Type-C standard only works this way in USB PD modes, otherwise voltage never varies from 5V. This means that QuickCharge 2.0/3.0 is completely different from USB Type-C charging methods.
But my 2.4A rated Type-A charger works, and my phone says it is Fast Charging. What's the deal?
___________________________________
Your Nexus may report as fast charging if the Type-A cable you use is not compliant with USB specs.
Threads on this forum have confirmed that the phone will pull 3A (or about 2990mA) from the stock charger. These results were verified using apps such as Ampere. When using 3rd party equipment (non-OEM cables and chargers), I would suggest using an application such as Ampere to ensure that you are not exceeding the maximum rating of the charger or cable. Doing so can be dangerous! It will also verify exactly how much current your phone is pulling to charge - information I've found helpful if for no other reason than to satisfy my own curiosity.
If you are unsure if your cable is compliant, you can test it using the methods found here: http://www.androidheadlines.com/201...usb-type-c-for-nexus-5x-6p-compatibility.html
So, how should you approach charging and connecting your Nexus to other devices?
___________________________________
The same way you would any other device - plug it into the best thing you have available.
For connecting to computers, use the best port you have available. Type-C to Type-C > USB 3.x to Type-C > USB 2 to Type-C.
For chargers, try to match OEM specs: 5 volts at 3 amps output using a Type C connector.
If you have to use an adapter (Type-A to Type-C), Make sure you use compliant cables!
What data connection speeds will I get on my Nexus using Type-C?
___________________________________
If you want to dig deep into this, look at the "USB Type-C Specification Release 1.1.pdf" doc from USB.org, it defines on page 19 the types of plugs and cables for Type-C, including the USB 2.0 Type-C port. Starting at page 57 it defines all of the wires/pins for the different cables. Comparing table 3-10 to 3-11, you can see that all of the SDP (shielded differential pair) signal pins/wires are missing in the USB 2.0 Type-C connections. These are your high speed data connection wires. The Vbus, Vconn, cc, GND wires are all still present to support Type-C power delivery.
So, in other words, there are USB 2.0 Type-C ports, and USB 3.0 ports. For devices which don't require up to 100 watts of power, or won't use up to 10GB/s transfer speeds, the USB-C 2.0 port may commonly be used. The Nexus 5X & 6P fall into this category. What connection speeds are you going to get with the Nexus? USB 2.0 speeds.

If I left any glaring omissions from this, please follow up. I'd love to have all the info we can get.
========================================
I wanted to put in this addition to the op. Thanks to @aaron_huber for putting this information up.
Aaron said:
A wire is a wire, but in this case the magic is in the charger, the device, AND THE CABLE. From the USB-C Wikipedia page:
Full-featured USB Type-C cables are active, electronically marked cables that contain a chip with an ID function based on the configuration data channel and vendor-defined messages (VDMs) from the USB Power Delivery 2.0 specification. USB Type-C devices also support power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA; devices can either negotiate increased USB current through the configuration line, or they can support the full Power Delivery specification using both BMC-coded configuration line and legacy BFSK-coded VBUS line.
The 6P does not support the full PD spec per Google, but it does use the "configuration line" which is an extra wire in the USB-C cable hooked up to an extra pin in the phone/charger to talk to the charger and negotiate extra current. If you don't have a USB-C cable with the extra pins/wires plugged into a USB-C charger on the other end that also has the extra pins to do the negotiation, then the phone will fall back to a lower current because the spec requires it. If you plug it into a USB-A charger or use a USB-A to USB-C cable then all you get are four wires - the "configuration line" to do the negotiation doesn't exist.
========================================
* Type-C capabilities exceeds previous USB Type-A 3.1 / 2.0 specifications:
** 2 way power transfer
** Universal plug type (reversible plug)
** Much high transfer speeds (10GB/s)
** Much higher charging capabilities (Up to [email protected] = 100W via USB PD)
** Alternate data modes for devices (Display port / Audio)
Known Type-C capabilities for Nexus 5x & 6P:
+ USB 2.0 Data transfer speeds
+ Full fast charging through USB Type-C ports or specifically designed 5v/3a capable Type-C chargers only
- Not Qualcomm QuickCharge compatible (may draw more current for charging than a standard USB port though, see below)
- No HDMI out (It is not type-c alternate mode capable.)
- Not USB-PD capable

Are 3.1 Type C cables backward compatible with 2.0 type C devices? I ask because if they are wouldn't it make sense for people to buy USB 3.1 Type C cables for future proofing vs 2.0?

USB type c is just the physical connector it has nothing to do with the usb 2.0 or 3.0 so you might as well by the fastest ones
What we do need to worry about is whether or not the cable itself supports charging at 3A 5v
Looking at the two, it appears that the Cable Matters product is a cable designed to connect a computer with Type-C port to a peripherals with USB 2.0 Type-C ports. (Like the Nexus 6p.) The maximum data speeds for this would be USB 2.0 speeds. Looks like a very nicely constructed cable - look at the connection ends, and polished metal. If all you were doing is connecting smart phones to your laptop, this is the type of product I would buy.
The J&D cable appears to be a full-feature type-c cable, and should support every supported type-c data rate. I'm not in love with the picture of the product though. Doesn't look quite as nice as the Cable Matters product. If you wanted to connect two devices with full 10GB/s connectivity, this would be the type of cable I would get.
It is my opinion that the two products are good examples of a well made USB 2.0 Type-C cable and a cheaply made full-feature Type-C cable. The full feature cables have to include more pins/wires, and are thus more expensive to produce.

Technically incorrect, but essentially right.
Assuming both cables adhere to standards, the Cable Matters USB 2.0 Type-C cable is (most likely) missing the data pins & wires needed to transfer at the rated Type-C 10GB/s speeds; however, it should still have all of the power pins and wires to charge at 5V 3A. The J&D cable, presumably being a full-feature cable, should support full Type-C power (100W) and data (10GB/s) speeds, and will also charge a Nexus at 5V 3A.

So for just charging it would make sense to get the better constructed cable based on your observations?
At this point, it's more about the cable you use than the charger. Using a backwards 3.0/3.1 compatible C to A cable will get you the same speeds as a standard C to C cable in USB use. The chargers coming standard with the phone are C to charger, so Google seems to be indicating separate charging and USB use here. However, compatible untethered chargers are available in both the Google stores and elsewhere. Just make sure if you're not buying the Google charger, you get one with the right specs.

So, if I read your post correctly, (very good post btw), if I were to buy a charger for work, I should try to find a USB-c to USB-c cable (5V/3A), and a USB-c wall plug, because the USB-c standard is what gets you the 15W? Using a USB-c to USB-a cable, even if it was rated for 3A, would max out at 10W?

This is a bit misleading, and while I see what your point is, I urge caution using such general statements. A one amp charger with a Type-A port, a computer's USB 2 port, a USB 3.1 port, and a Type-C port connected to Type-C adaptors will all produce different charging rates for attached USB Type-C devices.

So for just charging it would make sense to get the better constructed cable based on your observations?

I'm the type who thinks it's better to get the better constructed everything. So I'd look for a "USB 3.1" compatible C to C cable that was built well.

True, but I was talking about USB transfer speeds, not USB charging speeds, since Google seems to be indicating separate charging and USB connectivity use with these phones, as evidenced by them including separate chargers and cables with them. Actually, only the 6P has both, the 5X only has the tethered charger.

So, if I read your post correctly, (very good post btw), if I were to buy a charger for work, I should try to find a USB-c to USB-c cable (5V/3A), and a USB-c wall plug, because the USB-c standard is what gets you the 15W? Using a USB-c to USB-a cable, even if it was rated for 3A, would max out at 10W?

Yes, exactly.
Edit: According to what I've read, anyway. There might be something about 3.1 Type A ports that I'm not aware of which will allow 15W power. I know the 3.1 Type A port has extra pins. Just haven't been able to find in the 3.1 spec sheet a 100% absolutely for sure explanation either way. The Type-C specs pretty clearly spell out power states though, so I'm going to continue going by that. See attachment.
Second Edit: No, it would max out at 15 watts. The current I in amps (A) is equal to the power P in watts (W) divided by the voltage V in volts (V):
I = P / V.
3.0 Amps = 15 Watts / 5 Volts.
Or just buy a hard wired type-c charger like the one on the play store.

It won't power 100w, but I'm sure someone makes one that will.

It's currently sold out. They also have a 60W version with a 12' cable but it's $59.
Ouch that's a bit pricey!

Why not just get the 15W charger Google sells?

Ooh man.. Good thing I loaded two of them into my pre-order. Almost everything I pre-ordered is sold out.
I have an Android Box plugged into the screen in my car. It's running an Android Auto receiver. So I can plug my phone into the box, using a USB-C to USB-A cable, and Android auto works. Now I have a fully functional android auto, with one problem. The phone is charging at less than 500 mA. Does anyone know of a cable that could possible charge the phone with a car charger at the same time it's plugged into the box?

You are mistaken here. The cable does not limit the charge that goes through the phone. The limit that you are seeing on your phone is due to the USB port that you are using which has a max output of 0.5Amps.

Correct, but I need to stay connected to that usb port for data so I thought there might be a cable that had two USB-A ports on it. One for data and one for power.
greeting,
I bought a Nexus 6p and looking a charger (for car and EU wall charger).
I'm interested in whether it is compatible with QC and QC 2.0 3.0?
He prayed to the recommendation.
For Nexus 6P charging and date sync, the Type-c to Type-c cable is better than USB-A to type-c cable.
