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)

Well chaps, bad news. I don't think this is going to be possible. I spent 6 hours today trying various solder points. Couldn't get any of them to actually charge the battery. Seems to be some sort of system configuration thats interfering with how its detecting .

Did you look at /sys/module/msm_otg/parameters/floated_charger_enable? It might not be enabled. Here's a similar thread for the Moto G:

As far as I know, wireless charging won't work without a pattern lock or having that option set. My Moto X won't be here until next week so I can't do any testing until then.

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?
Anyone have any recommendations. That DON'T heat the watch up.
Somewhere on one of the android forums i found some links and ordered one. Just got it today. My stock charger is plugged in to the pc. Which we all know is small on amp charging. I tested the new unit out. from 90% to fully charged. And the back of watch was HOT. Too hot for my taste. I'm a long haul trucker so it will be my spare for the truck to take on the road. IT will be plugged in to either a 1 or a 2 amp charger. BUT, if the plugged into the pc made it that hot. I don't even wanna see how hot it will get by using a stronger charger and charging the watch from dead to fully charged.
So, for any of you that are using spare chargers. What's the recommendation?
If i remember right, some of the posts on that other forum mentioned the watch would get hot. But that's a little TOO hot for my taste for a 10% charge off the pc.
Hey snowwy66!
I bought an additional charger for my work desk and used several times already with good results (watch don't heat up very much, and charging process is nearly as fast as with the genuine stand). I just want to mention, the watch is charged by my computers USB port, so the charging current is 500mA (while the genuine charger provides 700mA to the stand).
I bought it in Amazon, just look here.
And as an annotation, a quick search would help you too, cause there is already a thread concerning this topic.
Best regards
i couldn't find the thread. Thus, i said thread SOMEwhere.
The one i bought, looks just like yours. Bought from amazon. Came from China.
I did find this sight though, looks like a stock samsung. http://www.mobilefun.com/50040/samsung/gear-s2-smartwatch/chargers.htm

Seems legit, but a little more expensive than the replica. My watch is charging right now and stays cool like the weather outside ^^.
guess it's not the same as yours. The one i got has a little tiny led at the bottom and didn't turn green when charge, instead it turned off.
thanks silber.

Looks like a counterfeit. I strongly recommend to NOT charge your watch with that charger.
My wife and I are getting new phones this year, and we really like the look and feel of the Ascend Mate 7, and in my research efforts, I found an interesting prospect. I love doing research, especially before I buy a new phone. The biggest reason for the upgrade (at least in my case) is to have the ability to use NFC again, more specifically wireless charging. My wife is using a Note 3 that I bought a Qi wireless charging receiver for, and so far it's worked flawlessly. I on the other hand have the Mate 2, which as you know doesn't have any NFC capabilities at all. Recently I have been reading about how the Mate 7 has NFC, but doesn't allow for wireless charging. I found a number of reasons from because of the back cover being metal it would block the signal, to they don't make a wireless receiver for the device, and among others, but I found something interesting that might solve the problem.
I opened up my Amazon Shopping app this morning, and I saw the 'Micro USB Universal Wireless Charger Receiving Patch' in my recommendations list. The description it gave for the item is that as long as your device has a micro USB charging port, this will give any device the ability to wirelessly charge on any Qi wireless charging pad. My first reaction was to jump for joy because I had solved the problem by which also sealing the deal of upgrading to the Mate 7. Here is where I think there may be a snag though. There are quite a few of these on Amazon that all do the same thing, some even come with a Qi wireless charging pad included, but they are all from brands that I've never heard of, and I myself being a very critical person am really on the wire. I hate wasting money, and I'm sure that I am not alone in saying that. So I want an opinion, because having the ability to not only use NFC again, but also the ability to wirelessly charge my device would make me a very happy man. I also love writing, so excuse the long post. Thank you in advance.
I think that would just be a phone cover with a charge coil built into the back and always plugged into the USB port. They'd be available for many phones. It may interfere with NFC, not sure.
A phone cover would have been a bonus, but nothing like that exists for the Mate 7 that I've seen. No this is a stand alone, very thin device. The description definitely details it correctly, it literally looks like a patch. I would post a link, but the app won't let me until I post a certain number of posts. Traditional Qi wireless charging receivers look similar, but they have adhesive fixed to the under side that allows you to attach it to the battery, and they have gold contacts that you match up with the contacts on your respective device. This has a long-ish strip that has a male micro USB attached at the end that plugs in to your device, and you can either permanently affix the patch underneath the back cover of your phone, or allow it to rest on the back cover.
I really miss wireless charging, and was hoping to find a dock or cradle I could pop my phone into so it can charge. There are a ton of Type C docks on Amazon. Anyone buy one or have any recommendations? Let me know!
Would not recommend this type, worked ok plugged into a PC for charging for a few weeks but not so well now. Never worked for docking to PC, always throws up errors - works fine with same cable (not the one supplied cos that was rubbish) and adaptor.
Haven't had a chance to test second battery charging capacity but judging by main bit it'll be bobbins.
It's also unstable, so if you go to swipe the screen (or even lightly brush it) it'll topple.
I was looking at that one..But it doesn't look like it would work with a case (out a thick one). I ordered this one from Amazon. Waiting for it...I'll let you know
https://www.amazon.de/dp/B01FMX7G92/ref=cm_sw_r_em_apa_LMaDxbPWWQ4DD
I was looking for one open on the sides and deep enough to get up into the case.
Waiting for it...I'll let you know in a couple days.

Basically the same as the one I wouldn't recommend. Even if it charged well, it's still pretty unstable and wobbles massively when you touch the phone. You'd need to stick it to something to stop the wobble.
Hmm... I'll keep searching
Edit: THIS OR THIS ONE
I bought this one:
https://www.amazon.com/gp/product/B017K46T1M/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
It's been great. Holds the phone firmly, sometimes too tight to get it off, but you'll get the hang of it. It's adjustable so it fits a case too.
It was a little finicky with some 3rd party QC2.0 wall chargers, but works fine with the LG Charger, Tronsmart charger and Anker chargers.
Just a quick review of my impressions of the WeCell dock.
I found it to be quite sturdy. Doesn't want to tip over, but you do require two hands when taking it from the dock as it's too light. Could be fixed to a surface to fix that. If your looking for something that doesn't take much space on a bed side table...it is space saving.
The USB connector pivots about 20 degrees which can make it a little tricky to dock, but after using it a few times I found it easy to dock properly.
I noticed that you should use the provided cable with the stock lg charger to get a proper charge. Was a little inconsistent with the Anker charger.
Overall it's a ok charger, but if your looking for something to use one handed, might want to check out the one posted above.

Does anyone know/own a magnetic USB type C charger for the s8+ that feature quick charge.
I want to know how well they hold up before getting one.
Dont hold your breath. If they are anything like the ones for the s7 edge they were crap and very cheap made. Easily disconnects from the cable. Didnt always fast charge. Need to ensure it attaches right if not it may not charge at all or charge at normal speed. Would not buy another ever again.
https://www.amazon.com/gp/aw/s/ref=...+fast+charge&sprefix=magnetic+usb+type+c+fast
Can't vouch if any of them ACTUALLY fast charge. A customer does claim out works on an S8 though.
Thanks for the feedback guys. I've reviewed numerous ones on Amazon and most of them are mixed. I'll keep on digging.
I'll post a link If I find something decent that gets the job done.
Please keep us updated!
Will do. I know the phone is still pretty new. So I'll give developers of the mag chargers for the s8 a little more time.
I'd like to find one so that I could just leave it connected and not have to worry about breaking my charging port..
