Why does my iPhone charger only have red, green, and white?

So my iPhone charger cable was broken, and i attempted to fix it myself. I opened the case and found the little green platform (don't know what does are called) which has label of W, G, R, and B. I figured those stand for White, Green, Red, and Black. However, when i cut open the wire from the middle, I found only 3 wires. Red, White, and Green. Since I also wanted my charger to be charge only, I searched online and figured that I only need the red and black cabled. BUT I CAN'T FIND THE BLACK CABLE ITSELF! Other than the red, green, and white, I also found 4 bunches of ultra thin wire grouped together. Are those the black cable's inside?

Can anyone tell me how to plug/tape the wires into the green platform so my iPhone would charge?

Thanks.

Alex, interesting little project. How about you post some images of the circuit board (green platform) and your cable and let us see what you see. Use this guide 在已经存在的问题里加入图片 to add images.

Please be so so careful - unless you’re a qualified electrician I would NEBRR meddle with wires, and even then I wouldn’t recommend it to anyone. Please don’t do this - massively dangerous !

As above, there are three colored wires (Green, white and red) and additional unwrapped thin wires in the bundle. All of it is wrapped in foil, a braided sleeve and the rubber on the outside. If you're looking to power a device - you need the need the redish orange wire and the loose wires, the loose thin wires can be twisted into a cord and soldered in place. This info is useful you want to power a device if the connection (the female cable connection shorts) . . . I directly connected an LED light, for example. . .

White is a data cable that is on positive volts .

Green is also a data cable but lives with the negative.

Red is hot.

You have a weaved wire that should be on the out side of the cluster of wires that is housed in plastic thus being your ground or 4th wire

Seven years after response: The black wire in some cables is left un-insulated. When this happens the wire is usually silver in color (stainless or aluminum as opposed to copper) Be careful that none of your splices touch each other or the ground (black/un-insulated wire or wires). For charge only use just the red and black or un-insulated wires (ground) and be sure that any unused wires like green or white are cut at different lengths with no frayed hairs on them and or shrink wrap the ends to prevent damage to your device.

I just opened a USB “C” cable because I just needed the other end to plug into a cigarette lighter for power. To my great surprise, no black wire. Red, Green, White and nothing else. So the Red is the power, normally 5 volts. Since there is no black wire you have to use the shield which is usually wrapped around a piece of foil. This is the equivalent of “Black” and at some point connects to pin 4 of the USB cable. Green & White are data wires.

Alright bro if your really trying to do this and just want it to charge you just need the black and red wire. If you want it to exchange data or download something off a different device your going to need the white which is the positive data wire while the green is the negative data wire and those above which I listed(black,red). Just make sure you connect those wires to the correct corresponding mounts or you'll short your it out

I have a green white an red an trying to figure out how to wire it to a red an black

Be careful. It’s not as straight forward as it seems. Tried it and I accidentally discharged my phone battery. It didn’t turn on but it got really hot and dead. I couldn’t tell it was happening until I picked it up. I was just board and was using my old iPhone 5. But still I paid $600 for it vs $20 cable.

If you look with magnification you will see there is a small uninsulated braided cable in there. It easy to not see it and you will Accidentally pull it down into the mess of strings and mesh wires that you want out of the way.

scratch that. I’m starting to actually learn something here I think. Maybe it’s the reason a cable would be built this way explains everything. Data is sensitive when transferring. You can’t have EMFS and other electronic noise interference interacting with data transferring . It’s an issue I discovered. Apple actually rocked it. They made two isolated power conduits. One for data and one for the fast charging . I think that’s why the mesh is often listed as a power cable & Shielding because of the mylar underneath the wire mesh and a decent layer rubber insulation underneath the mylar that protects the data cables.

If that’s true then unfortunately the entire cable and ? is solid state. The cable plugs are filled with Industrial strength epoxy glue the circuits come off the board before you can apply enough force to separate. I’m not testing anymore on my phone . Because once you cut the mesh you have a short and your phone won’t turn on until the mesh is reintegrated. I think

The further down the wire I strip I find more bare wires. Total of 2 so far. One copper and one steel color. Supposedly there is one more further down that’s the part that gets me. (3) ground wires (2) supposedly intergrade with the mesh and one gets hooked up. The copper wire is just as long as the colored ones. The other (2) are supposed to be down further. I will post a picture of what I have if I Can figure it out.

I don’t see a picture just the file name. Hope it comes out. I see it. First time I hooked up the 4 wires on the left. It discharged my battery fast. I cant find any solid info. It’s almost a solid state situation. It’s very difficult to remove the usb without destroying it because they fill it with glue and its a rock. The wire mesh can’t be reattached by hand in the same way it was originally. If it’s part of the ground or power then it’s basically destroyed on that alone.

I use to repair my daughters iPad charger due to an destructive rabbit all the time and since I didn’t know which ones where for data and which ones where for power I’d connect all of them separately and it’d work for charging (never tried data transfer with them). For some reason now when I try to rewire them they never work. I’ll try just connecting the red and silver. I always saw way more wires. Like solid bare wire, tiny strands of wire mixed with fiberglass fibers, red, green, blue, orange yellow and white. And it wasn’t just one cable. Maybe it was just that one manufacturer, but the ones I always got from Walmart so maybe it’s just that manufacturer. I do remember counting 8 separate connections though.
