So I noticed the wireless QI receivers have started becoming literally paper thin lately.
And with this girls teardown, https://www.youtube.com/watch?v=dweww9_RF2E#t=224
I think it looks like you could remove the thin plastic over the battery, and fit a QI receiver there.
Thoughts?

we wouldn't be able to remove that plastic piece because it hold the battery, but it is stil possible. i already did recon on some places to solder in a wireless charger.

Curious, but I'm looking at the flat cable that just lies there, under the M-logo. It doesn't appear to have any PCB at the end?
I wonder if they were thinking about adding a QI coil there, but decided it was too expensive?

That's my theory since the nexus 6 has wireless and they are the same chassis essentially . or it was for a fingerprint scanner they abandoned. Once we see a nexus 6 teardown we will have a better idea if we can do it.

Could have sworn I read somewhere that between they cable and a teardown of the software showing code for a fingerprint scanner, the original idea was to have the scanner. I could be wrong though.

Let's hope you're wrong then.
It would be really cool to have wireless charging, shame so few manufacturers add this.
The amount of stuff needed to make the coils on the receiving end is pretty limited, I could absolutely accept buying the transmitter separately, (like the turbo charger is now)
But I suspect the patent royalties are expensive, patents sure don't benefit users..

Looks like the nexus 6 has a different config then the moto x so as far as a plug and play solution, no. I have located 2 contact locations where we could solder in a qi coil. I'm just trying to work up the courage to try it lol
Here is a related question: without modding the phone itself on the 2013 and 2014 model I cant get one of the QI receivers to work. This is the one for sale on eBay / amazon / newegg with a micro usb end to plug into the micro usb port. It literally works with every other micro usb device i own including a Samsung bluetooth headset, several phones and some other stuff i cant think of at the moment... On the moto x 2013 and 14 I literally see no charge and see it actively loose charge over time with this device plugged in.
It may be tricky with the moto x. There are some negative and some positive reviews here for example: http://www.amazon.com/gp/aw/cr/B00MN3RR7Q/s=sd/ref=mw_dp_cr
There are also some reviews saying they needed to restart the device once while on the charger: http://www.amazon.com/gp/aw/review/B00H7FJX7M/R2YPDLOU1BD4QE/ref=mw_dp_cr?cursor=2&sort=rd
You can find more of those comments on the internet. Could you try that, and if it works clarify if you need to restart it every time you want to charge or every time you connect something else?
Here is another link for the original moto x: http://www.reddit.com/r/MotoX/comments/2gskxw/original_moto_x_wireless_charging_mod_qi/
Edit: you may need a screen lock, e.g. the pattern lock.
http://forum.xda-developers.com/showthread.php?t=2596469
An unrooted Moto G needs to be screen locked (I use the pattern lock type) or it will refuse to charge due to the missing pins. You can unlock the screen while it is charging as long as you don't lift it from the qi charger. (tested on 4.3 and 4.4.2, DE and FR firmware)

I tried pattern lock, didn't help. Wireless charging does not require a lock, my girlfriend has a droid maxx and wireless works without it.
As far as the module check, I don't have root on Verizon so I wouldn't be able to test it.

You are correct about wireless charging in general. I think the reason the pattern lock is suggested is because the wireless mod (even without internally mounting it) only provides 2 wires on the USB connector. Something about only having 2 wires, and not the data pins, is why the locking is suggested.
No worries on the module, just something I had seen while investigating. I don't know if the Maxx supported wireless charging out of the box, but it may have the flag enabled by default (that flag seems common among many Moto devices).
I'm coming from a Nexus 5 and I'll really miss wireless charging, hence my questions to you

The Maxx has it built in from moto, same internals as the moto x essentially. If we get root I could look at the module thing. I was lucky that I had access to a spare moto x main board so I didn't have to solder on mine. That won't be the case in the future.
I'm going to post all the points I tried so maybe someone can figure this out. I was able to get it to show charging but only right after reboot and it would stop once I took it off and replaced it. I have to emphasize it showed charging but never actually charged the battery, it would show charging in battery stats bit not in the status bar. I also use battery monitor widget to check the current and it never showed positive charge current. Once I was able to get it to details at as a USB charge, only happened once, still didn't charge though.
This all makes me think there is something screwy going on.

I ordered a Pure Edition (Cyber Monday deal was a great one) so if nothing else I'll have root to poke around. Pictures of where you tried would definitely be helpful. I think I saw some from you in another thread, but all in one place would make searching easier
A 5V near the USB port would be ideal because then we'd know its likely feeding into the battery or charge circuit. 5V elsewhere on the board may not be wired to the battery. Looking at the photos in that Moto G thread may give you an idea on where to poke around with a multimeter.
The charging after a reboot, and until you picked it up, sounds like maybe you did have it at one point. That whole "until you pick it up" is another thing mentioned by many in those Moto G threads.
What wireless charging receiver did you use (not your base station)? The one I ordered says "up to 1000mAh" but I had seen some at 500 or 650. A lower output rating may not be enough to charge the battery at all. One way to test this would be a very low output wall charger (one that puts out 500mAh for example) and see if the X shows charging when connected to that.
On a related note, how hard is it to disassemble the X? Some of the teardowns look like it could be a pain.

i've attache da picture of the points i used and the results are as follows.
1. shows 5v when plugged in. when wireless coil is attached to it, will power the phone up without the battery connected (doesn't boot, just shows a battery on screen)
2. pretty much exactly the same as spot 1
3. shows 5volts but doesn't power the phone
4. shows 5v but doesn't power the phone
5. you can't see it in the picture because the rubber cover for the usb port is on but there is a diode right behind the usb port. this one is the only port i was able to get it to say usb charging ONCE. other then that, acts the same as 1 and 2.
again i have to emphasize that even though they show charging initially, they never actually charge the battery.
I'm using a galaxy s3 qi insert 700ma. i think there is a mislabeling on some qi pads saying 1000ma but not considering the 30% loss in inductive charging. even ones with 1000 on them tend to charge around 650ma. some label including the loss.
As far as teardown it's not too complicated to get the back off, lots of adhesive so be careful to not bend the back cover. i have leather so that was a particular hassle as i didn't want creases in the leather. after that there are 17 screws to remove. i've included a picture of the ones you need to remove. the ones around the silver ring on the "moto" logo don't need to be removed along with the silver screw for the buttons.
after you remove the screws and disconnect the buttons and battery from the board the back battery plate comes off in one piece. one of the particularly hard parts about testing points is you can't turn the phone on because the power button is part of the battery plate. also when you put the battery plate back on and you have wires running to contact points it won't fit because there is a speaker "box" that sections off that circuitry. i combated this by using copper tape to essentially make my own tiny custom circuit pathways leading out of that box where i then could attach wires and run them up through the hole that the battery connector goes.
THIS IS NOT FOR THE FAINT OF HEART!
i'm going to write up a tear down guide for this phone. what section do you guys think i should post it in?

Not even worth trying, I attempted this mod on the Atrix HD which is done by connecting the positive terminal on the palm pixi to the +5v part on phone and it eventually worked but a usb had to be plugged into phone the usb wasnt plugged into anything but the phone wouldnt charge unless it actually detected a usb plugged in.
Unfortunately, I don't think it will happen. It is true that XDA doesn't care too much about warranties, but there is a big difference between hardware and software warranties. Accessory manufacturers aren't going to make something that you have to hack apart your phone for. What is worth more to you, a 30 dollar wireless charging accessory that you have to jimmy rig, or the warranty that protects your $650 investment? You can unroot easy enough to return to VZW but try explaning the wireless charging mod that's on there now.
I've been interested in getting a wireless charging solution for my phone, and while I have to look into it a bit more to figure out specifics for certain things, I think it may be possible to create a case that plugs into the USB port so we wouldn't void our warranties.
Designing the case wont bee too much hassle, a micrometer and some 3D modeling software. However we need to find a way to get a micro usb connector that has a 90 degree bend in it to go into the port without causing any sort of scraping. Possibly have the right hand side of the case hinged and secured by snaps on top and bottom? or have the connector itself removable.
So materials for a test setup would require:
Touchstone components
90 degree MicroUSB male connector
Soldering gun
Custom case
I don't have the setup to do this available to me right now, however I think the biggest problem would be getting a connector small enough to keep from adding a lot of bulk to the side of the phone. Heck, with it only supplying .42 A at about 4.8 volts, it may not be inconceivable to group 2 in a case for faster charging. I haven't worked with the touchstone charger myself before, so I don't know their size.
Anyways, food for thought, and a possible personal project once I get some more important things finished up.
Hi,
Signed up just to post my results so far.
Ive gotten razr HD maxx to charge through the USB port using a touchstone pixi back cover.
It works using the touchstone charging base but the usb wall wart that came with the razr hd. The amperage coming though was not enough using a motorola dedicated usb wall charger that came with my bluetooth headphones putting out 500mA. It charges a little slower using the induction charger. I need to figure out if this will work running off my cars electrical system as that is my main motivation for getting this to work.
To get the phone to go into charging mode you have to either short out the USB data wires or connect the D+ wire to a 2v contact on the touchstone pixi circuit. Connecting the usb D+ to the 2v contact hopefully will allow me to hardwire this setup directly to the phone and leave the usb port free if, assuming I can find enough room inside for everything.
The phone is charging right now on the touchstone base, estimate 2hr to full charge from 70%
Im going to try and shove it all inside the phone tomorrow.

I dont know if I can get this to work internally now due to soldeirng limitations.
There is just enough space to slightly force the phone back together (it does bulge) but the pins for the USB port are covered and recessed under the USB housing. There is not enough clearance for me to do a clean solder onto the contacts.
I can not find another trace for the 5v or D+ pin on the circuit board.
If i could remove the outer cover maybe but for now this is going to have to be a plug into the USB port/external mod until i either grow a bigger pair and try to remove the USB port or find alternate contacts to solder the leads onto.
EDIT: I actually just went for it and ground off the corner of the USB casing. And actually soldered the wires onto the pins. However the touchstone system will not allow this to work internally. The battey when laid on the coil will interfere with the EMF and cause an unstable voltage. It goes from a low of 4.8 to 5.5 v. Maybe someone thats an RF engineer can figure something out with the reflector.
Maybe if i get more motivation later ill check out a qi standard charging setup to see if its compatible. For now im going to find an outer case and just go with the usb plug use this externally.
Try picking up some foil tape and put it between the battery and coil. You should be able to pick some up at your local hardware or hobby shop. It may need to be touching the ground to be effective though. Depending on some things over the next month I might be able to start working on my own setup.
Tried that but no go.
With the foil covering the coil, the voltage fluctuates before the battery is even placed over it. I hope you can get it working internally, ive since used an otterbox commuter case to hold it all together.

In what order are you putting the components? Phone, battery then coil. Or phone coil then battery? Basically is the coil between the hardware and battery, or is the coil between the back panel and battery.
I can see where the issues would arise if it is between the battery and hardware. Both would be giving off EM waves if the device is on. If it is between them, try moving the coil to between the back panel and the battery.
Right now I can't afford to try an internal mod where I could kill the phone if I screw up, so until a couple things settle down for me I will only be attempting an external mod that fits in a case. If I can get the design right I may be able to make it so there is still a USB port available.
*Edit*
I'm sourcing/pricing components right now and you've already given me the voltage output, but how about the current provided by the coil? What I'm planning involves building a small circuit that would short the D+ wire only when there is no USB cable connected.
Anyway we can get some pics of the project in progress?

So I don't have the components at the moment to start my project physically, however as I said I am finding the parts I'll need. Apparently its a PITA to get male micro USB connectors without bulk orders, or importing from China. I'd prefer a SMT (surface mount for circuit boards) but those appear to be next to impossible. Anyways I've been able to find pretty much everything I need and just a matter of time till they get in.
My plan is to provide a clean circuit that would use the USB port on the phone to charge using the coil, while adding a new USB port into a phone case to still allow USB data and charging. However as the coil can create fluctuations in voltage and current, I want to have a setup that allows for it to be isolated while it is plugged in through USB.
Attached is just a quick circuit diagram I made using EveryCircuit, I need to refine it still, but just an example. Heck if you have the app rebuild it and you'll be able to see what it does. Left side is USB cable input, with a switch at top to simulate plugging in and unplugging, while the right is the phone side with the power source being the coil. The light/loads are to simulate the data lines and power lines and show whether the circuit works.
When I get the parts together I'll take pics and post a tutorial. I have some 3D modeling experience so I may even be able to design a custom case to put everything into.

the coil was sandwiched between the back case of the phone and the battery. The metal in the battery is influencing the flux going through the charging coil. The base is not always on, it only turns on when the charging coil is present. If not present the base seems to send out a pulse every so often to detect the presence of the charging coil inside the phone.
The issues arise once the battery is laid across the coil, the base begins to oscillate and the voltage begins to alternate. Also the coils seem to only work within a specific frequency range, but i dont have a signal generator or oscope to confirm this.
According to the battery charging app the base is putting out ~6-700mA to the phone with an 1A charger plugged into the base.
I found this when looking for QI receivers for my XT1092, and it appears to be designed for internal mounting!?
http://www.aliexpress.com/snapshot/6698695850.html?orderId=67539862048322
Has anyone else seen this, and does anyone, who has actually torn their phone down, think there's a free slot for this anywher?
I assume that it requires some form of modding to the battery mount, as that's the only area where you could potentially get a fraction of a millimeter to use.
Very cool find! The pattern of it looks correct to work and I do believe there may just be a spot to connect it. I just assembled a Moto X the other day. I have some pieces and will look tonight.

I was looking at a teardown video for the Moto X 2014, and this just looks like the NFC coil. Besides, I don't think NFC and wireless charging can share the same two contacts. I am pretty sure you would need a pair of contacts for the NFC coil and another pair for the inductive coil.
Edit: Or you would need atleast a chip onboard that can route all that current when charging to the charging circuitry and not fry the NFC hardware, and use it as a transceiver for NFC while not charging. I don't know if they even do things like that.

At the moment it seems as though the only viable option is to install a qi-receiver bought on ebay or a similar site and pair it with a case.
Not so bad i guess, since it probably is a hell of a lot cheaper and you get to choose whichever case you want.
Awaiting my Z5C now and will update when I have installed a qi solution.
That is impossible becouse that cases before have connection over magnetic charger and z5c dont have it.
Okay, bummer..
I thought they might solve the problem of the missing magnetic port by using the micro-usb connection..
Just wanted to confirm, I purchased a Qi Wireless Receiver that connects over USB - no dice. They don't have the "teeth" that microusb ports have and due to the water proofing the port doesn't turn on.

Shucks.. I just ordered one of those..
Tried various adapters and it doesn't draw enough power to charge. It just vibrates and turns the screen on but doesn't say charging.
Maybe you should try "detect the usb device" option

This.
I will be ordering up a high amp one soon to hopefully help me get my phone through the day. I'll report in if it does or doesn't work.
I am using this one

Looks nice! what kind of amperage are you able charge with tst receiver?
I'm going to be ordering this one:
https://www.amazon.com/gp/aw/d/B00YGV76LK/ref=ox_sc_act_image_1?ie=UTF8&psc=1&smid=A11ID9O6IRX38
Review show that it's pretty close to 1amp in most cases.
And using this so every time its in my pocket I'll have this in there charging it..
http://www.amazon.com/gp/aw/d/B018T...X236_SY340_FMwebp_QL65&keywords=qi+power+bank
Ampere shows 200-600 mAh (depending of the position)
Its working really good and its cheap, don't get why not all the companies install it in their phones ...

Just wanted to post to say that this is wrong. What it needs to work is a connector has the data pins to be connected so that it shows that it's capable of outputting higher than 500mA. I'm using the Zoer receiver that has that and it works fine. Amperage is between 260mA to 770mA depending on the qi charger that I use.
no, not really. This qi definitely works.

You just need one with 4 pins instead of the cheaper 2 pin ones. I have one which definitely works. Unfortunately, xdadevelopers doesn't let new users post links for some reason, so I can't help anybody with the link to the one I use. I spent a lot of time working out what to use and finally went into a 'retail store' to test the one I ordered before ordering my own z5 compact. If anybody wants the link to the ebay item, just email at [email protected]. Make sure you choose the 'A type' for the z5 compact. Works a treat. There is a lot of confusion about qi on the z5. Some people are saying that it is because of its waterproof attributes, you can't do it. Not so. This works perfectly and once on, can be used with any QI standard charging mat.
Guy, anyone tried with the quickcharge wireless pad yet? By the way, do we need to have quick charge supported receiver coils in order to use the quick charge charging pad?

I've never seen a quick charger receiver? I gave up on this in favor of quick charging at lunch
For those that have gone down this route a couple of questions please:
1) How has the QI receiver lasted if the phone is submerged? Did it just need rinsing in clean water and drying out or was it screwed?
2) Is there a maximum thickness to the case which I should worry about?
3) What sort of time does it take to charge up?
4) If I'm playing music or video will it charge quicker than I'm draining the battery?
Thanks!
I just got this one:
ASIN=B01E15W2ZA
and it works good with my Xperiy Z5 Compact. It charges with about 600...700 mA, something les than with a normal charger, but absolutely enough for my purpose - modt of the time I just want to recharge over nitght. It goes up to 100 %.
The included power bank feature can also be used via Qi, but probably smarter it to use it with a cable to not waste Your capacity as heat.
By the way: Even NFC works through the receiver!
But still I folded the receiver cable twice to position the receiver on the lower edge of the beackside of the phone. This way I avoid the risk, that NFC sensitivity gets reduced and I can line up the phone better on the charger, because it must lay quite exact on the cross.
i have qi charger for 5c and it works. i order plate fro qi and qi charger from ebay. just this qi sticker must set under some case. another way it is possible to broke it.
Hi I bought 2 keyboard folio from eBay brand new but it is like it haves a faulty battery. When I try to pair it with the tablet through NFC I press yes on the "do you want to pair the Nexus keyboard" but after some seconds it fails. But when I put the keyboard to charge it works. After I pair the devices and use the keyboard when I unplug it it stops working straight away. So I was wondering if this happened to anyone else and if it is any key combinations to hard reset the keyboard or something like that?
More people having the same issue!!!!!!!!

Has anyone found a way to replace the battery or fix the charging issue, battery not charging?
Has anyone tried using a portable external battery charger to power the keyboard, how long does it last?
Until you unplug the external battery.

I opened the keyboard and the battery seems to be dead because I tried to charge it with another charger and nothing was happening. On the keyboard I put another battery 400mah but still wasn't charging so I thing the board is faulty too. I will take a picture of the battery and upload it because I tried to find one but I couldn't.

Please upload any pictures you can, would be really helpful.
I was considering buying a simple small portable battery charger 1500-2200-4000~ and using it, but it would discharge too quickly, attempting to charge the faulty one in the folio. Also considered taking the folio battery/charging component and splicing in portable battery charger..
Another option I thought of, is using a male to male micro usb cable from the Nexus 9 to the folio.
I am using a generic micro usb charger works fine. I also bought a male to male micro usb cable attached to the Nexus 9 and folio, also works great. The keyboard hardly registers drawing any power.
Sorry for the late reply. That's the original battery of the keyboard which i tried to find but couldn't. The hard part is that it needs to be 1.5mm to 2mm of thickness Max so the keyboard top part can close normally. The other pictures is the modification I made replacing the battery but with a thicker one. It wasn't charging so that's why I came to the conclusion that it must be the board too that it is faulty. I connect the - and + cables from the charger to the exposed cables to charge the battery and that's it.

NO. The battery too is faulty. Because I connect it straight to the charger and it doesn't charge.

Hey... Just bought a brand new one with the same issue straight out of the box.
Have you tried measuring the original battery with a multimeter?
The battery protection circuits will sometimes protect the battery from undervoltage by not letting them charge any more as it potentially damages them...
One way to attempt to recover the batteries is to remove the protection PCB and charge them with a LiPo charger at super low amps till they get up to like 3.3v then letting the original charger and battery protection finish charging it... (Kinda dangerous if battery really is damaged)
These things sat on shelves for years.... I can't imagine the batteries didn't drain.
Edit: did you take the keyboard apart??? Lol... Is it glued together??
I took mine apart... This is not a reversible process lol... Checked battery voltage and sure enough... 0 volts.... There's no Li-Ion charger that will ever try to charge that battery as there is a risk of fire.
Looks like HTC cheaped out on the battery protection circuit and it didn't cut off the battery below 3.3v and let it get to 0v... Gonna have to try to recover the battery using my lab power supply to trickle charge it... My lipo charger complains and won't charge it at all.
I'm having the same problem. Just bought one of these on Amazon for $30 and was excited to use it. How did they charge $130 for this when it came out?? This is useless. I'm going to have to return this junk. Any solutions before I do?
The solution is easy.
I have effected this repair on multiples of the nexus 9 folio keyboard.
Someone said earlier that the charging circuit is bad in addition to the cell being at 0v. This is simply not true. For the charging circuit and the cell to both be bad you will have likely hit the lottery in a bad way, or shorted and caused damage yourself.
Truth is that as mentioned before their protection circuit on their $130 keyboard was not up to the task. I make the assumption also that they overpriced these so heavily they sat until their hardware choices became apparent by making them DOA after the cell's voltage fell too low.
Someone stated that opening the keyboard is irreversible, this is also untrue, it only requires a bit of skill and patience.
Take it for what it is, because I would never recommend someone to revive a cell that had been sitting below 3.2v, it's just unsafe, but this is what worked for me as I didn't feel like digging through china stock to find a matching cell.
The cell is at 0v, so the fix is simple, connect another similar chemistry (3.2v-4.2v) cell in parallel (between the protection circuit and the cell.) I just used and 18650 from a laptop battery. Let's call this a "jump start." Start the charging and disconnect the second cell. Red charge LED should remain solid and charge cell 1 to 4.2v and you are good to go.
As far as the details, we know that the cell is on the left side, so only heat and slice adhesive from just beyond the corner to the center, slide your tool under the cell to remove the adhesion from the main body and carefully slip the cell out far enough to get at the contacts in order to get between the protection circuit and the cell.
main points
1 DO NOT PUNCTURE THE CELL (ALUMINUM TEARS EASILY)
2 DO NOT DAMAGE THE RED AND BLACK LEADS FROM THE PROTECTION CIRCUIT TO THE MAIN BOARD
3 DO NOT PRY OPEN THE OUTSIDE CORNER NEXT TO THE CELL AS THIS CORNER IS MORE SUSCEPTIBLE TO DEFORMATION THAN OTHER AREAS
Probably best left to a skilled tech, but it can certainly be done.
The adhesive htc uses is much like hot glue, so after scraping the old glue out reseal and press with a hot glue gun (precision tip recommended,) easy peasy.
On a final note, shame on you htc (and google.)

I want to try this repair on my keyboard. do you have pictures where to connect the wires.
I have a laptop battery
i have the case pulled apart
Just want to make sure that the wires are in the correct place.
The folio battery has a USB jack at one end and a switch (on/off perhaps) and a blue light at the other. What's happening when the blue light blinks?

i meant if i take the keyboard apart.
I ordered another on off ebay, but i used the suggestion i thiunk i saw on here. I have a microusb OTG plugged into the nexus 9 and running a usb to the keyboard. it is supplying enough power to run he keyboard. also it does not seem top drain much power at all.
I'm typing this message on the folio keyboard. if the other keyboard folio has the same issue then i can at lease use this solution to use the folio.
now i need to order a shorter usb to microusb cord so i dont have to rubber band the cord and look sloppy when carrying it around
Thanks for that. But what about the blinking blue light?

That is paring mode if in not mistaken.
Nah, it's definitely a charging light. Doesn't blink when pairing but does when a USB charging lead is plugged in. Goes off after a couple of minutes, which confirms what we all know: the keyboard doesn't/won't charge.
Picked up one of these new from Ebay. It doesn't seem to want to charge and will only work when plugged in with charger. Anyway to get it working? Guess it's a return
ATTEMPTED HARDWARE MODDING - the title may be a bit misleading
Longtime Note series diehard fan here. I absolutely cannot live with wireless charging, that's even more important to me than removable batteries, I have had 2 phones have constant problems with wear on the USB port, and my lifestyle is already adapted around Qi charging, I have multiple wireless charging pads, and have, for the past year, never plugged in a USB cable into my Note 3 except for flashing roms and copying backups to my Thinkpad. Now, I am considering a new phone, and my options are either the LG V20, which has no wireless charging but a removable battery, or an S7 Edge with wireless charging and no removable battery.
As title says, I am interested in getting true wireless charging for the LG V20, not some crappy plug-in wireless charging adapter crap. What I'm thinking is finding some point on the motherboard, most likely on the positive and negative terminals of the charging port, and soldering wires to it, and the wires would be soldered to the exposed contact points of an old Samsung Note 3 wireless charging add-on. The same idea has been implemented in a Oneplus One successfully before. Now, obviously, if there were the wireless charging reciever, the metal back cover would be interfering with it. So instead, I will buy a cheap TPU case so that I protect the battery but allowing Qi charging to pass through. Please chime in, and let's facilitate a discussion here. Also, there have been previous threads discussing this idea, including a thread where LG customer service apparently confirmed that LG was planning a wireless charging accessory (in Jan 2017), obviously take this with a grain of salt. The general idea is that either customer service was giving us a load of crap, or LG V20 has the hard ware to do so, but LG never bothered to develop it.

Similar idea successfully implemented on Oneplus One

Also, something else to note, would wireless charging be Qi or PMA standard? Back in the LG G3 days, the AT&T and Canadian versions (which was basically the same phone) had a PMA reciever, whereas Verizon and other variants used Qi.

Possibly varying by region, but very possibly both. While Qi seems to be ahead there are now quite a number of chips which implement both, attempting to figure out which standard the other end uses and adapting. Since consensus is only emerging slowly that looks like the way things are going to end.

Ok, thanks for replying. So now, the question is, how to proceed? Should we try to implement the mod like the OPO I was discussing in the original post? Or should we try to find the necessary software and hardware to enable purported built-in wireless charging? I personally am in favor of trying to solder a Qi receiver onto the charging port, as my main goal is reduce plugging a cable into the USB port so much, but maybe there is a more elegant solution?
I have attached a picture below with the NFC contacts circled. Do you see any points on the motherboard which could potentially be wireless charging contact points? Or are people suggesting that those 10 random metal dots distributed around the phone, are the wireless charging contact points? Because that would just be hella weird.
Post #19 on this thread is what I'm referring to for a reference image: https://forum.xda-developers.com/v20/how-to/lg-v20-wireless-charging-support-t3486488/page2
Also, here are some pictures of charging ports for LG V20. Do you see anywhere that could potentially be used to solder wires on, to attach to a 3rd party Qi receiver? Personally, I am guessing that only the AT&T variant will be Powermat, everything else, like int'l or Verizon variants will support Qi standard. Knowing LG and their tendency to reduce a load of regional variants with random differences (like the LG G6 wireless charging/DAC/64gb storage debacle).
Another wireless charging thread. Pic on page 2. https://forum.xda-developers.com/v20/help/lg-v20-wireless-charging-t3471387/page2
Anyone else have anything to comment on? If not, I'll probably just solder wires to my charging port once my LG V20 arrives off of aliexpress (which might be a while)
I just got my v20. I'll be poking at it over the next couple of days to see what those points actually do.

Hey, that's great! I have access to AutoCAD inventor, so if you can provide me with the exact dimensions I could try to make a 3D printed model of a non-metal LG V20 back cover, over Christmas break. Hopefully I will have time...
I didn't get anything obvious when I checked with the multimeter. I'm going to probably tear this down on Monday and see if I can find anything conclusive. See if the traces from those points go anywhere.

Ive had a look inside my phone and most of the pins seem to be for grounding, connected through a resistor or capacitor. I dont believe there is any pins for qi charging. Look at the pins for the nfc, they are located close to one another, the rest are spread out at almost regular intervals to provide grounds for the battery cover. Also, i dont think connecting a qi receiver to the usb is a good idea, it may confuse the port into thinking an accessory is connected, and i dont think the receiver would like getting backfed 12v when you connect the phone to a QC charger. I think Real qi charging seems unviable for the v20, Unless someone has a service manual to check the schematics.

I wish I had seen this before taking my phone apart. I didn't see anything from the pins going to any of the chips on the board either. Dunno why they skipped wireless charging on the v20.
