[ALERT] TYPE-C PORT and TWO accessories FRIED

So I was charging my phone like usual. And I was slightly aware that there was a compatibility issue between QC 3.0 and Type-C.
HOWEVER, tonight at about 12amish GMT. I kept smelling a burning smell... Which I thought it was my cat. but then when I decided to charge my phone using my Lumia 950 XL charger. I discovered the port had been burnt, and the cape and phone where burning ****ing hot! I felt the type-c plug from the charge against my top-lip and I got burnt...
I'm writing this a bit panic-y as I want everyone to just know TO BE CAREFUL. I'm not sure what exactly caused this as I have looked after the phone as if its my baby. Always case and a screen protector. I have a feeling this is down to compatibility!?
Anyone with similar issues, suggestions or such?

The Lumia is c to c right? If so, yeah there were lots of reported issues where people used various c to c cables with a c brick (most were pixel or nexus chargers that I saw) that had the same issues you did. Think it ended up being that the 10 doesn't have the right safe checks in place to stop charging at 100%, and it just keeps trying to push 3 amps even when fully charged (could be wrong about that though)

mmm.. the phone was charging from almost nothing... I think I was charging it from about 20% using a zuk z1 cable plugged into my computer that was connected to a usb 3.0 port. the cable is 3.0 standard and the phone is 3.1 if I rememeber

ive just added images into the original post

You don't Push Amps, you pull em, you Push Voltage.
The phone decides how much amps it wants to draw.
More likely missing cables inside the cable or bad quality Connector.
Was it an original Microsoft Cable from the 950 or bought afterwards?
P.S can't see the pictures. Just my bad Internet?

UPDATE: ok so, I've taken it back to the place I brought it from and they sent it to the repair centre (carphone warehouse). They've turned round and said tis water damage but I disagree as I do not like to keep my gadgets in places that are potential for issues. Will be taking it up with the shop. failing that, Trading Standards.
CAN SOMEONE HELP ME; does water corrosion look similar to that of corrosion caused by excessive current or connection shorting?

I had a ps4 controller do the same thing. it was cause by the cable was not 100% plugged into the controller port. it was still able to charge a bit but after awhile I noticed a burning smell... same results

QC3.0 cannot exists as TypeC output, also the standard is not supported by USB consortium which developed USB Power Delivery instead.
Benson Leung warned people, that type c to type c charging should be avoided.
Even HTC10 does not follow the official usb specification and uses QC so best any user can do, i using legacy USB type A to type c cable and using charger with USB A output port. Also all cables must have 56k ohm resistor, cheap one come with 11k resistor and could damage power charger or the device. Check Bensons google+, he even linked to Tronsmart chargers which were out of specification and should be avoided.

Yeh, I became aware of this when the QC3.0 was released. Though, my assumption was because I'm connecting between usb type-c to the phones type-c it wouldn't charge off the QC3.0 standard.
Initially, I was using the Nokia type-C charger which came with my Lumia 950XL. It charges at 15 Watts (5V, 3.0A). I had used this the majority of the time and hadn't gone wrong. Sometimes I'd use a portable battery charge which charged at a generic 5V 2A AND a Samsung nexus 10 charger which was a usb female and charged a the same rate.
I would've assumed (also judging from the new releases by QUALCOMM) that QC3.0 phones would either charge of USB standard OR take advantage of QC. I've never used type-c to type-c charging only because I never had the capability. There is a slider in the settings menu to use USB3.1 standard but again, never used it. always done this through a usb3.0 to usb type-c cable.

HTC10 charges normaly from any standard legacy USB port like your old HTC M7 usb wall charger or notebook usb ports. QC3.0 uses data lines in usb cable to provide power and this method is not approved by the USB consortium, thats why you can not also communicate with your phone in QC3.0 mode, because there is no free lines for data left. You can either fast charge, or switch to standard usb mode and transfer files without QC3.0.
USB TypeC standard forbids strictly manouvers over the cable like QC does. For this, the newest Chromebooks and Nexus uses approved USB Power Delivery.
The "problem" was, that Qualcomm is also part of research and development of USB Power Delivery but yet, they in the same time were developing QC3.0. Was it for pure marketing purpose or to fill the gap between USB PD going live, we can not tell.
The only way now to end this confusion is to wait for Qualcomm to switch for USB PD as a successor of QC3.0 because there is really no point of two competing charging standards which one is spec certified and the other is not.

so would this mean I will need to set my phone to file transfer mode if I want to charge from USB?
Also, for reference, is there a way to disable quick charge 3.0 (which I assume may be present in the build.prop file OR am I thinking more noob like)

No, you must understand how usb and QC3 works. I will try to explain it as simply as I can.
Legacy USB have 4 cables inside, two for data transfer, one for curent and one for ground.
If you plug your phone to the usb in notebook, you can charge and transfer data in the same time.
What QC3.0 does, it is using the data paths for providing additional power, so when you plug it to your QC3 charger, it uses all the data routes/cables in USB only for additional and faster charging, so the data connection is blocked in this mode.

Ok, just came back from Carphone Warehouse. It looks as if the phone has corroded more during the time I've given it to them and the time its taken for it too come back.
The colour of the corrosion was of a greenish hue.

I'm awar eof this, but my question is if it can be disabled on the phone or not.

Never heard of disabling QC. I do not think that HTC will provide any tool to disable built in chipset feature.

Non HTC 10 chargers?

I don't fully understand why, but I've read that due to our phone using USB-C for charging, that I should probably just use the OEM cable and charger my phone came with. I have an LG G5 charger and cable laying around, but the specs are slightly different than the 10's. Would it damage my phone to use that as a spare charger? Also, can somebody give me a simple explanation why USB-C is delicate for quick charging?

I'll rephrase the question, not statement, in a way that might be easier for you to understand. Here it goes: Can somebody give me a simple explanation as to some people allege USB-C is not compatible with Qualcomm QC?
Also, since my question is about quick charging, and since the LG G5's charger uses quick charging, that's the kind of charging I want to do.

i would check the output voltage, htc can accept ~5volt ~9volt and ~12volt.
if you have a good usb-a to usb-c cable (stock or somethink like aukey (NOT ANKER)) i would feel comfortable becouse the phone and the charger communicate with eachother on what voltage to charge.

To be even more precise, on just one model ID of their PowerLine USB C cables, the rest of their PowerLine USB C cables are fine.

Anker’s Powerline 3.1 Gen2 cable has a flaw that causes it to “remember” the charging voltage for a laptop that it’s plugged into, then accidentally provide that higher voltage to a phone unless it’s unplugged from the more powerful charging base. This can overload your phone and destroy it.
Anker has already replied with the following recall:
We are offering all of our PowerLine USB-C A8185011 users a full refund.

Type c charging cables

Hello all. I have a quick question. I have bought a type c charging cable that has just arrived, it was sent from in my country to my location in less then 3 days. Off ebay And after purchase I read about how type c charging cables can destroy your devices if you buy a knock off, or a cheap cable or not made properly, by any means this cable was 13.00 AUD. It's 3 meters and it looks very thick and quality looks good. It is generic though. No branding.... So I'm wondering if it would be okay to just use this as a charging cable, and use the original for File transfers. I also have a Spigen cable on the way but I do not want to wait to use this one. Is there any chance that this will be okay to use?... Attaching a photo of the cable

The htc 10 doesn't use USB charging; it uses Quick Charge 3.0.
USB charging has its standards, separate from the connectors and separate from Qualcomm's standards.
Qualcomm states that QC works regardless of cable and connector. However, the htc 10 is picky about the cable and I've not found a rhyme or reason for it. I have a Type C-to- A cable that won't QC but several micro cables that will with a micro-to-C adaptor.

Basically the cable must have a 56k ohm resistor in the type c connector which tells the phone how much power to draw to prevent over current. Usually this is signified by a longer plug and the resistor should be stated in the ad if you can remember where you bought it from. From eye balling the cable you photographed it looks fine. I think it's more of an issue with Nexus phones anyway since the 10 uses a different standard in order to maintain compatibility with qc3.0.

More accurately, the resistor tells the USB-C device that it's hooked up to a legacy "device". Type C to anything being legacy. Anything but type C weren't "designed to handle" 3A of current that the USB Power Delivery can output at 5V.
So if you have a Nexus 6P or a Pixel or whatever that uses USB PD:
if you use a type C to type A cable with a 56kOhm resistor, the phone is going to know that this is a legacy device and it won't attempt to draw more than the "Default USB Power" which is 5V0.5A for USB 1.0/2.0 and 5V0.9A for USB 3.x.
But of course the device will also look past it and see what output current the charger actually advertises it is capable of and then charges at that current the charger is capable of..
But, here's the big problem.
What if you use a type C to type A cable with a 10kOhm or 22kOhm resistor?
That cable is going to tell the device that it's
a) not connected to a legacy device (56kOhm resistor would mean legacy)
b) it IS connected to 5V3A or 5V1.5A (10kOhm/22kOhm resistor respectively) output.
It's going to try and draw 3A of current if the cable has a 10kOhm resistor in there, whether or not the charger can actually output that.
Danger here is that different chargers will respond to that differently.
The charger can either fail spectacularly (read: explode, catch on fire, something bad) or it will just trigger OCP (over current) and not charge if it has the protection or it will just try and cope with it delivering as much current as it can and potentially overheat and fail in some fashion.
Imagine hooking up your Nexus 6P or Pixel to your laptop with a "bad" type C to type A cable.. Those ports are not going to be able to handle that kind of power unless they're something special sauce.
For a little bit more cohesive explanation, read this
http://www.androidauthority.com/usb-type-c-and-3-1-explained-656552/
As for our device, we don't use USB PD. Some have said that the HTC 10 is compliant with it but I don't know if that's true or not.
However we use Quick Charge. Quick Charge doesn't look for resistors, it looks for the other chip inside the charger and talks with that chip, essentially doing a digital handshake before they initiate quick charging.
That prevents the charger from outputting anything higher than 5V unless the device specifically asks for it.
So, in theory, ANY data cable should be perfectly compatible with QC.
Data cable meaning that the D+ and D-, teh data, connectors are hooked up.
QC performs the digital handshake, and subsequent voltage/current adjustments, by talking across the D+ and D- conductors.
If you have a "charge only" cable or a PortaPow "data block" adapter, it means that only the V+ and V- connectors are hooked up and as a result QC chip in your 10 can't talk to the charger to negotiate the QC.
As for why some type C to type A cables don't support quick charge. I have no freaking idea.
I've got one cheap C-A USB 3.0 cable that I bought from ebay and it's a weird cable...
First time I tried charging it was in the car with a dual port (A) QC3.0 charger. Phone said slow charge, for faster results use the original charger. Didn't try again.
With the stock charger I'm testing at the moment, I first got 1.8A (after 1A>1.3A>1.8A over a minute). Unplug and plug it the other way around I got 1.7A and then it dropped to 1.4A. Third time I plugged it in the same way I plugged it the first time and now it said slow charge.. Plug it again the same way and now it charges.
Could it be that the cable either has a 10kOhm or a 22kOhm resistor in there? Maybe. Idk. Don't have means to test it right now, but I'll probably gut the cable later and measure it when I have time.
Moral of the story: come on guys, buy good quality cables from reliable brands for charging. They're not expensive.. Aukey, Anker, PortaPow, you name it. There's a lot of them out there.
I'm personally using the PortaPow cable for charging my 10, only 1 meter length available at this moment but if you want longer or shorter lengths, message them. They'll make them if there's enough interest.

Except that these guys don't make the cable that I need (or I just haven't been able to locate one).
I need a ~6-ft/2m cable with a 90-degree-to-the-front/back elbow on the USB Type C connector like the one shown here:
...and black...no goofy colors.

I thought I knew the correct cable to purchase (I only bought this phone 5 weeks ago and I need to buy 1-2 backup charging cables.
I always bought cables from Monoprice.com (for my M8 anyway) because they were decent quality, they had 6" lengths available, they were pretty cheap, and they had goofy colors (I'll take anything to break up my day a bit).
But now I am not sure which cable is correct. Is the USB version irrelevant with the HTC QuickCharge functionality? So I can get either v2.0, v2.1, or v3.0 USB-C to USB A?? Also, I will go to another vendor if need be, but most of the cables at this website do not state a resistance—just voltage and amps.
So this would be one I might get because it seems OK...

Proper means they all have 56k resistor, just like jesus said in the bible. So they are fully compatible with HTC10 and can be used with any QuickCharger or USB PD charger without risk of drawing too much power resulting in explosion. 56k resistor is the main key here and mr Benson, a Google engineer working on devices using USB PD specs which *need* a proper 56k resistor Type C cable, tests himself various cables using a hardware tester and posting reviews about good and bad cables.

Q6: Does it matter what type of charging cable is used with a Quick Charge adapter?
A: Quick Charge is designed to be connector- and current-independent. Quick Charge is designed to be compatible with a variety of formats, including:
USB Type-A
USB micro
USB Type-C
Proprietary connectors
Quick Charge 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 or cable current capability.

Unfortunately you did not read the big post on this page along with the article about delivering power over usb cable.
Both QC and USB PD require cable with 56k resistor to work properly. Hence the cable for Google Pixel or HTC10 is the same. Each standard deliver power in its own way over the same cable.

"It's own way" -- correct. USB-PD requires 56k termination for legacy device compatibility. Our devices use QC, not USB-PD.

Both QC and USB PD require cable with 56k resistor to work properly.

If this is true, it goes against Qualcomm's specs that I linked that you may or may not have read for comprehension. Qualcomm states that they have no/zero/nada/nicht/nill/null/zilch cable requirements for QC. Also, QC predates USB-PD. The two have nothing to do with each other.
More from the big post I allegedly did not read:
However we use Quick Charge. Quick Charge doesn't look for resistors, it looks for the other chip inside the charger and talks with that chip, essentially doing a digital handshake before they initiate quick charging.

Do you have an authoritative source that shows that the 56k terminator is necessary for QC3 to work on the htc 10?
I cannot find it on Qualcomm's site or htc's site. Google Pixel and Nexus 6P sites are not authoritative sources for the htc 10 or Qualcomm Quick Charge.

I did not accuse of anything, I am not a prosecutor.
99% of cables used to charge your and mine HTC are USB A (2.0)to USB C cables. The resistor is needed so you will not draw to much current via USB A connector which is not rated for 3A. Lower value resistor will force to draw to much from USB 2.0 spec connector and cable. Simple as that. So your digital handshake between chips is worth essentially nothing if they will indeed greet and meet over cable that is not rated to pass a 3A high current which will lead to fry something.
I suggest to read the discussion in comments section on Benson Leung G+ profile. Do not get me wrong, I wasted my time to go all over it and I do not see point to go back couple of articles again just to point a few most important comments by Benson. You could do the same, because it does not matter if you believe me or not. Bottom line is, you need a 56k resistor USB A to USB C cable for HTC10. Same cable which was shipped to you by HTC in the box. If you do not believe, then take a sharp razor and disassemble your cable. They're cheap so you will get yourself a brand new one very fast.
So, check your oem cable, ask Qualcomm and HTC via mail why you need a cable with 56k resistor. Simple as that.

The conclusion you drew is faulty. The pull-up resistor is needed to protect legacy equipment; it has nothing to with Quick Charge or cables/connectors being "rated for 3A" (they aren't--chargers are).

So, no, you do not have an authoritative source for Quick Charge cable compatibility for htc 10.
Did you read the Qualcomm link I sent? It does not require the pull-up resistor. htc FAQ only says "buy our [only one, short, overpriced] OEM cable"; htc tech support never replied to my query.

Ok, it is no use to continue this further. Everybody will do as they want and will be happy. You can recommend cables without or with any other lower resistor and I will recommend with 56k as I did before that actually are working.
Still I can wait for your cable disassembly as last proof that I am completely wrong but I think that will not change anything at all in this discussion.

USB type C cables and chargers

This will be my first usb type c device. I'm sure a lot of you are upgrading from the original pixel. Can you guys recommend cables and chargers that you have used that you liked? I'm sure there are a bunch of people in my situation it can help to stock up on this stuff before the phone comes. And yes I know there is a list of approved cables, etc.

I'd look at Anker or Aukey for chargers. They should have a couple PD-2 chargers. They also sell the required cables.
The Pixel 2 XL will come with cables and a charger in the box though.

Thanks. I know it comes with some. Just trying to figure out work, bedroom, etc.

Make sure the cables you buy have a 56k ohm resistor.

I have followed this info on cables and chargers. Great information.

Purchase via Amazon or store, whichever you prefer. It's the one that charges the phone rapidly with Power Delivery.

I would never get a cheap Chinese/no name version. From what I've read, if it doesn't have a 56ohm resistor, it has damaged phones.
You can also check on Amazon and read reviews from those who have purchased. Not worth saving a few bucks to potentially damage your $900+ phone.

If its OEM, I don't think there will be any issues. I'm sure people may have multiple USB-C items and I'm sure these news outlet and reviewers have multiple USB-C cables and plugs that they just use the same one over and over.

DO not get any usb c cable/charger so many of them don't follow the standards
Only get one that has been tested
bad cables and charger in best case can charge slowly
in worst case can damage the phone or explode
follow https://plus.google.com/collection/s0Inv
and only use good cables
from the top of my head, the good ones are from
belkin - anker - CHOETECH - IOGEAR - Veckle

The car charger your linking has history of being bad.

Mark for deletion please.

As far as I can tell, Benson Leung finds issues with every Aukey product he reviews. I'm contemplating the BlitzWolf BW-S10, as I've had no issues with the BW-S5 or BW-CB3, and their reputation appears to be clean. The supplied cable is USB-C to USB-C, right?

USB type C to type C on motherboard with N10+

Hey guys.
Can I use cable which came with my charger (not sure if it's OEM Samsung one,suppose so) which is type C on both ends to transfer files between cellphone and my motherboard which has type C port on back of it, without a risk of damaging cellphone?
I'm an idiot using Bluetooth to share 4K video files but it's daaaaamnnn slow just because I'm anxious that somehow the short could damage the phone.
Never used type C on my MoBo (Formula VIII) and I have scond PC which has type C port on the case and on the motherboard too (Crosshair Hero VIII).

Nope,just to transfer files,but I got issue first time that somehow it got disconected though I haven't touched nor cable nor phone,phone was lay down on bed.started transfering and then it got disconnected,probably cable is issue,bending,flexing etc...
I'm not even sure if I got brand oem cable since it's yellowish but it could be from tobacco smoke ofc...

That is usually a driver issue. It happens. The most stable is definitly a USB 3 to USB-C cable, get a properly shielded one and it goes smoothly.
It's either on Thunderbolt or the Samsung/Windows Driver. This is a known issue with some laptops.

How will I know it's shielded?
Where does it make difference compared to regular one?
I have the one which came with my Ulefone Power 5S it's type C to type A,kinda very thick cable.
But affraid to use it since it's not Samsung one.

If it's thick it's probably well rated and shielded. Xiaomi for example have great cables. The shielding is to reduce possibility for external signal influence. Think of it this way :
Power delivery can vary from 15watts to a lot (100 for example) - charging is specific and in these cases when using a power brick avoid non standard cables - always check if it's thick and have 2 lightning bolts on both USB ends- the lightning bolts are Thunderbolt PD delivery logos and are rated for high power delivery.
Try and always use original cable for power delivery (charging) as an accident with a non manufacturer cable can void your warranty and may not allow you for a claim. Always check on the box if you buy new, the wattage supported 15 to 100 watts in cases.
Data transfer is less of an issue since usually there is no power delivery a usb 3 cable is rated at most for 15watts max. but data transfer does not pass power on the cable. if it's thick it will be shielded and will only use the data transfer channels, not power.

Can I picture you the charger and you tell me if it's OEM or fake?
Btw so can I use cables for other brands for transfering files,such you mentioned (Xiaomi),or any other good quality usb 3.0 to type C cable?
So how will I know the cable is good quality,by the thickness?

Use short, quality cables; the longer the cable the more suspectable to noise and interference it is.

Sure, tranfering data is no issue, just avoid the C port for the moment until PD delivery is standardized. PD delivery has too many options and is not standard between brands.

what is PD Delivery,and why to avoid type C cable,don't understand?

It will either fast charge or not.
Get OEM bricks/cables and there's no fast charging issues.
No issues ever though with the Samsung ones.
For slow charging and data transfers any quality 3ft cable will do.
Longer cables tend to fail quicker and cause problems that outweighs their convenience.
