[OnePlus 6T  Guides, News, & Discussion] Syndor:
So this all began when my phones back crystal panel broke on a fall.

I decided I had to replace it, so I ordered a new Transparent one, since like Jerryrigeverything I love to be able to see the electronics.

While I was at it I figured, why not add wireless charging to the phone? It should be possible, so I looked around for a guide, and I found this one:

https://www.instructables.com/Add-Wireless-Charging-to-Any-Phone-Using-the-LG-V2/

That was way sloppier than what I wanted, but it was a good read, and you can read about what he did.

You will need, a multimeter to check for continuity

A soldering iron, one that can regulate heat so you don’t damage anything, and with the smallest tip you can find

A donor charging receiver

Time and patience.

After that

With help from ifixit (link: https://www.ifixit.com/Teardown/OnePlus+6T+Teardown/115698 )

I opened up the phone, and since ifixit said there was no fingerprint connector you can just go at it, heat, and separate.

Once inside, disconnect the battery first.

The OnePlus 6T has a different design, there’s no pcb for the usb c on the speaker area, it has a connector that goes up to the main pcb, that snaps right next to the battery, since they had to make room for the optic fingerprint scanner.

So I removed the battery, so I could strip the layer of safety glue and make a little more room by peeling away a couple of layers, otherwise this wouldn’t close.

I started probing around with my multimeter for continuity, to do this, I connected the usb type c wireless charge pad (this one: https://www.amazon.com/gp/product/B087TW7MGK/ref=ox_sc_saved_title_4?smid=AQB8EOE9WF3ZF&psc=1 ) after I stripped the protecting plastic cover (to make it even thinner, and to see the insides).

So you connect it and probe the +Vbus and the Ground on that pad, at first I was a bit baffled, since it had pins on both sides, why if it isn’t carrying data, then I realized how stupid I was being, of course, it’s because it’s usb type c, you can plug it in both ways, and it needs to have the correct pins either way.

So I managed to probe around for continuity, and found out these are the correct spots.

I had to remove some of the plastic on the NFC cover to allow the wires to pass, you can see on the final image the route the wires had to take.

As you can see, I also jumped both grounds since it wouldn’t work if I didn’t.

The first one is beefier, but it wouldn’t fit since everything on the PCB was bigger, the thing is, they charged at the same rate when tested with a usb type c power meter around 680-700 mah of charging power with a 10 watt wireless charger.

I ended up using this other one which was cheaper, and also smaller, not as sexy, but that’s the price to pay.

so all that was left to do, was place a nice thin sticker on my battery (I miss the red battery days) to make it look a little bit better, and close it up with the transparent back cover (also from amazon).

As a side note, I placed a USB C to C power meter, and these little things do seem to have sensors for when the battery is full, so they don’t overcharge or overheat.

So I left it overnight with a 65 watt PD USB C to C charger, and a wall plug power meter, and once it’s soldered in, it also seems to drop down the charging, and it also stops giving out heat when it’s fully charged, so there might be something on the small PCB for charge detection, or maybe it’s the phones own full charge detection and it stops asking for power, since this would be the equivalent of being connected with a cable.

Still, everyone should operate at their own safety and I’m not responsible if you set your house on fire, but I will continue leaving it overnight.

It charges slowly, but I can also plug in my dash charger, and again, it doesn’t overheat, the PCB on the wireless coil receiver seems to be doing something, maybe.
