[Q] Would wireless qi mod be possible?

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?

Wireless charging

Is there a speed difference on qi vs PMA?

Bump

no there is no difference, just different wireless frequency.
here is a quote of mine in another thread:
me said:
the Samsung will work with either charging technology, but Qi charging seems to be the winning "standard" for wireless charging, almost all newer phones are more likely to come with Qi compatibility rather than PMA. so while the PMA might work fine, chances are your $8.99 discontinued charger might not be compatible with your next phone. Nexus 6/5/4/7, Sony Xperia Z3, Motorola, etc All use Qi. i would much rather spend $10 more and at least i know it will work with my future phones since i upgrade almost yearly..

you won't find any wireless charger at 2A.. they're all 1A at most. i doubt we would ever even see a 2A pad as i can imagine the amount of heat it will generate..
i have this dock/pad: http://www.amazon.com/dp/B00RGIK7P/
which IMO is better than any samsung overprice pad. phone can be held in portrait, landscape or flat like a pad and has 3 coils so it doesn't matter as long as it's touching the surface. it even holds my tablet, and works with 2 of my other devices. just make sure whatever you buy it's Qi and not PMA because even though the S6 supports both, i think in the end Qi wins and becomes the wireless charging standard. most phones coming out are Qi and at least you know the pad you buy will work with future devices.

PMA will survive with the help of Starbucks.
They are in the process of merging with A4WP, who are working on Rezence, so won't be going away anytime soon. This is a magnetic resonance system which improves the range to about 5cm - WPC are working on something similar for Qi. Presumably A4WP are interested because this will allow their new standard to be be backwards compatable with existing PMA transmitters (Starbucks!), so they don't have to compete with Qi from scratch.
I would expect most phones with wireless charging to support both standards in the future. It doesn't really cost anything extra and ensures their customers can just charge anywhere.

Yeah that maybe true, but if no mobile phones use PMA, it will still be still be a problem, LG G3 AT&T version supports PMA before, now Galaxy S6 supports PMA, a technique couldn't be developed without the support of Samsung, Moto, HTC ...

it will most definitely help spike more PMA device sales, but i don't think one phone will help it long term.
it's only fading slightly slower because of Starbucks as someone else mentioned, and the fact that they are part of the PMA Alliance/Board (including ATT) which might be why they would probably fight tooth and nail continue pushing PMA on mobile devices.

Do you guys actually find wireless chargers useful? I never used one before, but I keep looking for reasons. The cons outweigh the pros by too much at this time for me.

For me, it's all about the convenience.
I'm never in a situation where I need to charge my phone right now. I typically charge overnight and it gets me through the whole day. If I use it more than usual on a given day, I just plug it in for a bit before I head out if I'm worried it won't make it to bed time.
Having charge pads set up in my common places (nightstand, desk at work) allows me to catch some extra volts when simply putting my phone down like I normally would. Add the fact that the wireless charging then means never having to fumble with cables and plug in the phone ever again, and you get used to the convenience pretty quickly. Plugging in a phone starts feeling like an outdated concept, like something that belongs on a smartphone of yesteryear.

Honestly, it's the cool factor - for us tech geeks at least. Is it useful? Probably just as much as your cable charger in my opinion - less so with the introduction of fast charging...

Hey I don't know for certain, but I also read somewhere that these companies are pushing PMA more because it can transmit and control other type of info, such as how long a customer has been on charge, and then send a coupon to their phone, etc. I don't know if the Qi technology supports that type of technology. You think this might also help?
I am thinking they are probably thinking from a business perspective, where they can charge people to charge their phones...

If you've ever had a micro USB port issue, then you'd appreciate the ability to wireless charge. I plugged and unplugged my S4 so much that the micro USB port stopped working properly. I ended up buying a replacement USB board on ebay. Not going to have to worry about that with the S6 since I'll primarily be using wireless charging in usual charging situations (nightstand, desk, car).

[Q] Found a flex cable QI mod? Maybe?

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.

Wireless Charging - Mate 7 SOLVED?

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.

Retrofit wireless qi charger receiver

Hi,
I want to retrofit wireless charging capability with one of those thin receivers you can put between your phone and the case and then plug into the usb port. The only thing that worries me is a coil or antenna or something which is sitting on top of the battery. I can be seen in this disassembly video: https://youtu.be/kNzDbb-lJzs?t=42 This would probably be covered by the added receiver. What is this? Would covering this up be a problem?

NFC.
It doesn't seem like a good idea to me.

Mhm, ok. If I don't want to use NFC anyway would this be a problem? I mean, the phone should be able to handle beeing placed on a qi charging station (if someone is ignorant that it does not have this function) without induction of any harmful currents into that antenna, right? So I would just loose the NFC functionality if I shield it with the receiver patch.

My reaction was not about NFC, it is even possible that it will continue to work, maybe it will be less sensitive. I just expressed my opinion that I personally dislike your intention, because I don't think wireless charging is a killer feature for the ZF6 that we have to regret not having. Moreover, our battery size and space in which it is located and cooled, and so on is not at all adapted for continuous wireless charging and higher charging temperature.
After all, we don't charge so often with our big battery, and when you charging by cable, you charge more environmentally and faster than with the best wireless charger. That is to be remembered, and that is what I meant and what was my point.
For me NFC and big battery are killer features, but wireless charging isn't.

OK, I am getting your point. I just bought this phone, and was not used to having a battery that can go two days easily. I have qi chargers scattered around everywhere (car, office, living room ...) to top up my battery whenever I lay my phone down somewhere. That is starting to seem a bit pointless. I just discovered the function to slowly (and therefore least damaging to the battery) charge and reach 100% at a specified time. Perfect for overnight charging.
Let's give it a few more days to see if I still feel the urge to retrofit wireless charging.
But from the purely technical standpoint, I had another thought. The qi charger only switches on the charging field when it detects a compatible device set down on it. So it would not do that if an untouched Zenfone 6 would be placed on the charger, and there would not be any danger of inducing currents into the NFC antenna and damaging something. Now, if I retrofit a charging pad the charger actually does produce a field when the phone is on it, thats the whole point. No idea how much current would actually be inducted in the NFC antenna, but I am very certain it is not zero. Does someone have the technical background to at least make a guess?
