Why would a cable not be recognized/charge at all? - OnePlus 6T Questions & Answers

I have purchased some cables (usb-C to usb-A) and was surprised not to have them work at all on my 6T. I'm aware of the general usb-c problems, and the fact that "fast" charging is only available via the OEM Dash charger cable combo, but all of the other non-OEM cables/chargers have at least been recognized, allowed data transfer, and charged the phone, all be it, at the slower rate.
Is this a common problem? I'm interested in some of the technical details. What is the negotiation protocol for the microcontroller on the phone that would actually decline to acknowledge the connection at all? Has there been a driver/software update that identifies the current/resistance on the cable as a mismatch for the phones tolerances? I thought that the brick circuitry itself managed power delivery...
Just FYI, I have the OEM cable/charger which work fine. I also have a belkin cable and numerous other chargers (5V/5mA , 5V/1A , 5V/1.5A , 5V/2A , 5V/2.4A , 5V/4A) with which I get a data connection and basic/slow charging, which is really all I need. I used these new cables, supposedly rated to usb 2 and 5V/2A, on all of these chargers and my PC with no recognition/charge at all.
Thanks for insights.

Are you sure it's not just bad? I always slow charge my devices so I pretty much always use aftermarket cables, they work fine on the 6T. I use the same cables on my 6T across many devices, it's not an issue. Have you tried this cable on another device?

Distinctly possible. I tried on both, the only two, devices i have that use usb-c. This was a relatively cheap multipack from usual questionable sources, I tested several of the cables and all failed the same way on both devices across all the different bricks mentioned. Cables had reasonably good reviews, and I thought it unlikely that they were all bad. Just wanted to lob in question to see if there was another potential issue to be wary of.

Shouldn't be. I use several different brands of cables, no issues. I know I'm always skeptical of reviews at alot of places because so many of them are fake. What brand cable is this?

Are you testing all with the same power source? I know some power bricks or USB ports in vehicles vary. My wife's Kia only charged her LG G7 but no other devices including my OP6T. That's why I stick with the OnePlus car charger and power brick

[Q] About the new (double) micro USB charger cable

So I just bought the Note 3 yesterday, nice beast.
I briefly talked about the new micro-USB cable with the seller, who explained that it was completely compatible with regular micro-USB cables (I was starting to be disappointed : just when everyone was adopting standard micro-USB, they had to change that !).
But, he added it was nevertheless recommended to use the new charger cable. We both wondered why exactly, what could happen if using only an old regular micro-USB cable. Time to achieve charging is different? Can it damage the battery or reduce its life ? Or is it just to get USB 3 high-speed transfer capability?
As I now have (after having Galaxy 1, 2, and 3) many micro-usb cable everywhere (office, car), I'd like to be able to safely use them.
Thanks for your answers/leads.

Your original micro USB cables are perfectly OK to use. If using an mains AC charger, your phone will charge at whatever rate that charger charges at (500ma, 1a, 2a etc) irrelevant of whether you use a micro USB cable or micro USB 3 cable.
The only diffrerence really, is when charging from your computers USB ports. With the micro USB 3 cable, your phone will charge at a faster rate.
I havent even used my micro USB 3 charger that came with my phone yet, ive just been using my old chargers.
Nothing adverse happens, just use em like you would in your previous phones.

It won't hurt anything...
Your phone will charge slower and you data transfers will be slower. That is all.

USB C cable question

Just wondering before I buy a oneplus 2 does the cable work on every other USB charger plug like all android phones? I'll have to order a non UK plug but if I don't even need to use the supplies charger and can just plug the cable into another one it'll be perfect
It should work, though charging speed may vary and might cause eventual damage to the OP2's battery.

Yeah seems to work on any that I have tried. I have tried it on at least 5 different chargers with different USB leads and a Type C adapter for the leads. Just varies the charging times.

Samsung USB-C Cable is Unique?

TLDR: I am only able to achieve a stable data connection using the Samsung usb-c cable that came with the phone. I've had my S8+ since the first day it was available in the US, Apr 21. And I've had this problem since that day.
Details:
When I plug my phone into a computer (transfer files, etc) or my car (Android Auto), it always works fine with the Samsung cable. It almost never works with any other usb-c cable I've tried, seeming to succeed only if the cable sits just right in the port. If it happens to work, and I move the phone/cable at all, it stops. On a computer, the "you plugged in a device" dialog pops up over and over again really fast (1 hertz).
I've tried it with both usb 2.0 and 3.0 ports on a couple towers and 3+ laptops
I've tried at least 3 different kinds of cables and at least 10 total cables. The cables don't sit loosely in the port or anything. They fit snug and hold fast, as I've come to appreciate about usb-c.
The other cables all work fine with other usb-c devices I have -- Pixel phone, Nexus 6p, Nexus 5x, Chromebooks, Nintendo Switch controllers
Charging works fine 90-95% of the time with other cables. When it fails, it slow charges, saying "Ensure the cable is plugged in properly" or something like that
I see articles online encouraging purchase of all kinds of non-Samsung usb-c cables to use with the S8
I would conclude the port is loose, but the cables all fit snugly, and the Samsung cable *always* works. I don't have to wiggle it in the port or anything--no effort at all.
This hasn't been a big deal for me until this week. I have usb-c cables all over the place I can charge with, and I carry the Samsung cable in my backpack for when I need a data connection. But now I have a car with Android Auto, and want to keep a valid cable in there.
Has anyone else experienced this? I searched around some, but couldn't find anything.
I'm using three different brands of type-C usb cables, micro usb cable+included adapter (micro usb to C). All are working fine.

It's a big I aqh3 I'm 99.9% positive. My MacBook pro power cable is as good as they come but it flaps like 3x then just says fail on my phone screen despite it working fine lol. It does not do this on for example the eng rom for root
I bought 3 type c cables from 3 different manufucturers. Only one of them doesnt work as advertised. Whenever i plug the phone with the cable the humidity sensor is switched on and it tells me the phone port is wet and i can not charge. Cant fidn any logical explanation but thats what i get

I experience the same problem. I haven’t tried the original cable. I just gave up on PC cable cause I never really needed it. I just wanted to use my usb c desktop connector to feel cool since usb c isn’t popular on a desktop yet. But yea constant disconnects unless you plug it without moving it, a slight wind can blow and cause it to disconnect. If the OEM cable works no problem, I’ll just buy one from a4c android store or amazon.

Dead usb port?

Hi guys, I'm new here and could really use some help
I finally upgraded to the 6T from my OP2 yesterday. I got a T mobile variant (in great condition) and wanted to convert it to international. The problem is I can't seem to connect it to any computer. I have tried 5 computers and 3 different cables, the phone just doesn't get detected. USB preferences remains grayed out and windows doesn't even detect something is being plugged in.
I have tried installing the OP drivers, and qualcomm drivers, made no difference.
I also noticed that the usb-c to headphone jack doesn't output any audio through my earphones. Dash charging isn't working either.
Is my usb port damaged? It seems like theres no data going through it at all

Well if it's not even charging or playing audio then yes, I'd wager the USB Port is damaged.

Regular charging works, just not dash charge. And the buttons on my earphones can play/pause music, but there's no sound output. I've been reading a few pixel forums, this seems to be a common issue with pixel 3's. Was just hoping to see if others here have faced similar issues and how they got around it
Have you tried to clean port with toothpick or brush also your dash lead or charger may be faulty, dash charging will only work with dash lead and dash charger. Also usb type c are prone to failure i would clean and replace lead and go from there before juming to charge port replacement, if necessary ctdi in poland do a great job and authorised repairs for oneplus

Flashiing with USB3 port & cable likely to cause brick?

I've read of at least one person saying usisng a USB 3 port bricked their PH-1. Have seen other posts saying same on other phone threads but wonder if really due to other issues eg poor cable (like Essentials one!), using port not on motherboard etc Just trying to judge risk.
I now only have laptops with only USB 3 ports. i have a high quality 6" (15cm) Belkin data cable.
How many of you have flashed succesfully with USB3 ports? Is it a higher risk than normal?

I also heard about this being a (potential?) issue. However, I have been using a laptop with USB3 ports (Dell Latitude E5440) for the last couple of years without any problems. I successfully flashed my PH-1 from this laptop at least a dozen times. It does have one USB2 port, but I never used it, and always connected to one of the two USB3 ports. I only used USB2-compliant cables, though (4-pin B connectors).
Thanks mate, hopefully I'll not have any issues either!
