[Q] Modifiy Nexus 10 For Qi Wireless Charging?

In short, could we slap a Qi-compliant coil in our Nexus 10, wire it to the battery, and win?
The coil itself is pretty thin from what I've seen, and there is a bit of room in-between the battery and back plastic (the people with creaky and buckling cases should know about this).
I don't know if there's an actual control board that is needed, but perhaps the coil could be hooked either directly to the battery, or even through USB (that way you can be notified of charging). If a control board is needed, then this might be a bit harder than expected, unless the board itself is pretty thin too.
It looks like someone's managed to do something similar to a Nexus 7 already and had good results (even enters docking mode): http://forum.xda-developers.com/showthread.php?t=2070851
Edit: Instead of routing the coil to the USB or battery directly, we could even hook it to the Pogo pin area, like the person did for the N7 coil mod above.
I'm willing to give this a try, but may have to wait a few weeks till I can get the funds for a coil and for it to ship to me.

According to a-post-at-techchrunch-i-cant-link-to-cause-im-a-noob, the Nexus 10 has Qi already... is it wrong? I haven't opened my Nexus 10 to check

I have openned up my Nexus 10 and dont remember anything for wireless charging being there.
I saw someone mod the Galaxy nexus to enable this sort of thing and from what I remember you should be right Espionage, just as simply as you think. And yes there is room to do it.

I can find no reference to the device on the offical Qi website. This makes me highly skeptical that Qi is already present on the N10, perhaps they confused it with the N4?
Search for yourself if you'd like: http://www.wirelesspowerconsortium.com/products

As slow as the Nexus 10 already charges with it's stock USB cable... do you really WANT to charge it with Qi? :laugh:
You might have to charge it for a week from 0% to get to 100%

Any further developments?
Hey Guys!
Is there any further developments on this possibility? :fingers-crossed:

Why not just use a pogo cable.... you would have to plug in a charging pad anyway.

Nexus 10 Wireless Charging Solution
I know it's been some time but I'm kind of surprized nobody posted a solution yet. I just had a Nexus 10 open and noticed not for the 1st time the pogo pins at the bottom that Google never even put to use. I can't even find an aftermarket docking station for it. We aren't talking about Apple here. Anyways the closest I've seen is a magnetic pogo pin charging adapter cable probably sold mostly to people who broke their USB ports. It seems nobody picked up on sewermike's comment. They DO have pogo pins and with a wireless coil (2-4 chained together) you could wire them to the + and - of the pogo pin cable easily. Also if you have access to old Nexus 2nd gen back covers you can get them there or on eBay cheap. It might be slow like TheAltruistic says but if you have a wireless device charging coffee table which I'm seeing more and more you can just set it on that. If I have time I'll do video or at least post my results.

ive got the pogo cable, if you can buy it do so - its well worth it, i think i paid £15 and i totally stand by it.
as for wireless charging, you can get wireless charging receiver cards that plug into the micro usb port, with this you can either plug it in and bend the cable around the tablet and hide it inside the case or plug it in and have it hang outside, you just rest the card on the charger.
please remember that is isnt a perfect solution as the card will get hot and overheat and stop charging or you'll spend all day charging the tablet.
i use to wirelessly charge the nexus 10 but id rather stick the pogo in

Won't wireless charge!

So I read that this device has wireless charging but I can't find an instance of the problem I'm having. Is there something special you have to enable to get it to charge with a qi pad? Neither the nexus orb nor my og lg pad will charge it. I thought the protective plastic might have caused this but even after peeling it back I don't get a charging indicator. Seems my nexus luck follows me wherever. I got one with a nice display and no physical defects seemingly on the first try. Am I doing something wrong here?

Mine charged wirelessly right away, there was nothing I had to manually enable. I tried it on 2 different LG WCP-700 Qi chargers.

Mine had the same issue, and it was the connectors for the coil on the inside. if you feel like opening the case you can try to clean them. that worked for me or just exchange the unit.

Mine was working and now it isn't as well.

I would check the back and see if it feels like you have space. in the case.

Mine seems to be charging fine on my Nexus 4 Orb.

Can you tell us what tools you used to open the device? I'm guessing suction cups, perhaps from iFixIt? Or did you go the spudger route?
As for cleaning the coils, are you referring to the 2 or 4 gold pressure contacts that are present on the back of the casing once the device is opened/separated?

Not to sound like a ****, OP, but a little searching would have shown you this thread, about the same issue:
http://forum.xda-developers.com/showthread.php?t=2379718

I used a thin guitar pick and started at the bottom of the Screen next to the USB charging port and slowly opened it to the left side of the screen, ( the Side that does not have any buttons) and slowly went up the screen to the top and keep going till I was able to separate the the device from the back unit. But I caution you to be careful as you can easily break the case as IFixit mentions in.
the 4 connector are the ones, that I am referring to, mine device looked like they were not clean. I cleaned them up and after putting together again the wireless charging works.
hope this helps

Yes same problem with mine. Qi Charging did not work and neither did the NFC, although it did on the first day. Opened it up and cleaned off the gunk off the four contacts and Qi and NFC started working again.

Thanks for the advice... Everywhere was sold out near me. After a 55 mile drive to best buy I exchanged it... Way better than waiting on play store agony. This replacement seems better. Screen so far is the same nice quality and everything actually works. Wireless charging is fine. Good to know that this is easy to take apart. My problem though with opening the device is that I tend to get creaks etc afterward. I did search prior BTW... I guess I didn't look hard enough

I wonder about those units where people have not tried Qi Charging or NFC and how rampant a problem this is.

Is a wireless charging mod for the AT&T / T-Mobile LG G2 feasible? My musings...

I've been mulling this over, and here is where I'm at so far...
Can we develop a relatively easy / straight forward wireless charging mod for the LG G2, similar to what has been done for the Samsung Galaxy S3/4 and Note 2?
At first it doesn't seem that likely, as there's not much space behind the cover of the G2, and not being designed to be removable, is relatively hard to get off. Maybe not that hard though. Some looking around here at XDA shows several people who have removed their back covers to rough them up and get rid of the shiny plastic / tendency to collect fingerprints, so it seems taking it off / putting it back on without damaging the phone is quite possible.
The main thing then is finding a coil / receiver setup thin enough that it won't cause bulging or fitment issues, which may not be possible while retaining the "stock" back.
I suspect we may be able to get around this by using a "snap on" style hard case and some padding to maintain the over all look of the phone, effectively mounting the coil in the resulting gap where the back cover once was. This isn't my idea originally -- I've seen several people do this when using exceptionally thick aftermarket cases for the Galaxy S3, where they either removed the stock back of the phone entirely or built the Palm charging coil in to the back of the case The main issue with this sort of setup would be the area around the buttons / camera lens as it would have a space there and likely collect dust and dirt / be more likely to get damaged. If the stock back becomes available (like via ebay, say) relatively cheaply I could see some people buying a spare and modifying it relatively easy to cover this problem area, we're talking about a thin piece of plastic after all.
The only remaining issue would be getting the coil connected, then. I have yet to open the AT&T version or see a picture of one opened (all the pictures I've seen thus far have been the VZW version with the wireless charging built in) but as I understand the AT&T and T-Mobile versions likely don't include the pogo pins used to connect the charging coil for the VZW version, so we'd have to find somewhere else to connect, likely to the charging pins of the USB port as has been done for other wireless charging mods with earlier phones.
All in all this probably won't be a common mod (we're likely in solid "warranty voiding / can't easily be reversed" territory here) but I don't see any definite reason so far why it wouldn't be doable.
Would anyone else (ideally someone with more "involved" hardware modding experience -- I've just done the Palm Touchstone mod in a few Samsung GS3s) like to chime in here? Suggestions?
I love my G2 and I imagine ROM / community support is going to be great since the Nexus 5 is looking to be based off of it, but after only a week or so of ownership I'm really missing just setting the GS3 on the Touchstone at night, and while the USB port seems sturdy enough I don't like risking it every time I charge.

I have an Optimus G Pro, but a family member got a G2 as a gift. I have Qi, but they don't (T-Mo version). I'd be interested in helping out; just not sure they'd let me open theirs up. Are you sure it lacks the pogo pins? And, additionally, for Qi, could the patch in the G Pro be potentially helpful?
I'm surprised this hasn't gotten more momentum...

You can compare the pins in these pictures. Notice the extra 2 contacts by the NFC contacts on the Verizon version.

Here we have the same LG G2 and you get wireless charging on one and not on the others. You have to buy the flip case for them based on your carrier. It's rather retarded if you ask me. They should all have the wireless charging.
Not just an LG thing either.

OP, to you answer your question, this isn't possible. I run an android parts shop and we have torn down a D801, D802 and a VS980. I have a D802 myself and wanted the wireless charging ability. My technician said it wasn't possible, the wireless charging module from the VS980 has no place to connect to on a D80x board.
:crying:

The best solution I think would be to solder the coil straight to the USB charging lines, but if that isn't possible I guess you could connect the coil to a USB plug and then just connect the plug on the USB port and leave it there all the time (you'd only need to remove it when you connect the phone to the PC). You would need to find a rather small USB head (ideally one with a 90 degree angle) so it doesn't get in the way.

Agreed. Something like: http://www.ebay.ca/itm/Type-A-Micro...t=LH_DefaultDomain_0&var=&hash=item51b4da088d

I actually did this recently to my Verizon Galaxy Nexus. I used a Note 2 Qi Receiver pad. I took my soldering iron and melted plastic casing away to expose 5V and GND where I soldered 2 beads for connection. I then fitted the Qi Pad over the beads and adjusted for a good connection. Added Double Sided tape and applied my Incipio Feather Case. When I removed the case, the double sided tape kept the Qi Pad on the case, where I permanently installed it.
I have the actual back plate cut in half to keep the camera whole sealed, but the battery and Qi pad is exposed. I basically built myself a Qi Charging Case. Remove the case and replace the back cover with a whole one, and it's gone.
Wireless Charging WAS a requirement for my next phone and luckily only the Verizon variant had it. I saw it as fate.
But conclusion is that just because the internal case doesn't have charging leads available, doesn't mean you can't make it happen. To pour salt in the wound, the Qi Charging works fantastic on the VZW model. I use it every day.

I really hope something comes up with this. I've got the ATT D800 and came from a Nokia Lumia 920 with Qi. I still have the Nokia charger and would LOVE to go back to it. I know some people say it's not important, but those are people who have not tried it yet.

My post was specific to the G2. There is obviously no causal link between wireless charging tech in general and spotty GPS reception but it seems to be the case here. Anecdotally, it somehow has an affect on the VZW model's ability to acquire and maintain a lock.

I hadn't read that yet. Sounds like they put the charging coil too close to the GPS antenna.

I've just ordered one off eBay: http://m.ebay.com/itm?itemId=261329370615
They're reasonable cheap so I figured I'd try it out and see how it performs. Not going to solder as of now though

Wireless charging, a new concept (DNA transplant)

The lack of wireless charging was a huge downside to me, a trivial thing I know, but I used the hell out of it on my DNA.
The M8 metal case causes a problem for wireless charging, so the concept I have is as follows:
1. Using a 3d scanner/printer design and print a plastic back
2. Transplant DNA wireless charging to M8
Number 1 is easy, I have access to the materials
Number 2, questionable:
Is the DNA's wireless charger connected to a battery or in some way to the motherboard? I cannot find any information on this that would give me a green light to start the project. Any input form anyone knowledgeable in the area will be appreciated.

Haven't people been using the receiver under a case that connects to charge port with a flat right angle connector?

It appears, after looking at wireless charging on the DNA and several other phones, it actually goes through the motherboard itself, so a transplant is a no go.
2nd thought: tapping into the usb port, splicing the wireless receiver directly to it.

Wireless charging, a new concept (DNA transplant) is very interesting and unique.
When i read title of thread i really surprise about it but now i get some information about it.

QI charging

I wanted to share my QI wireless charging project, I had a small turn/twist while doing it.....
I am using a BLUBOON (Make sure it's TYPE B and not TYPE A, found it to be the best one out there, but more expensive $20ish) and an LG G3 NFC + QI but the QI part does not work, it must be some special kind of charging coil? Anyhow, I just cut off the center and contacts from the QI section of the LG G3 sticker also put a piece of cardboard behind the contacts so they would actually reach the pins and on the BLUBOON I cut off the microUSB plug and soldered the + and the - to the USB port. Nicer and cleaner solution than what I had in mind (soldering the 2 pins of the LG G3 QI to cables and running them down to the USB port, making the back undetachable...)
Here is my original post on the OnePlus forum:

Hi m4f1050,
LG G3 only has the antennas on the sticker, the NFC board is inside the phone (as usual) and also the Qi board (usually in the sticker for other brands such as Samsung !). That's why it didn't worked.
Take a look at mburris mod : http://forum.xda-developers.com/showpost.php?p=57765939&postcount=235
I think it's rather easier that way
Anyway, good job and thanks for sharing !

8 soldering points vs 2 soldering points ... IDK if it's "easier" but hey, 2 options! I also get +400 mA with my setup. At 25% it said it would take 6 hrs to fully charge..which is half of what a 2.1 amp wall charger (3 hrs to fully charge on 25% batt) Tested both ways.
EDIT: Here is a quick snapshot of my charge mA's (I've seen 400+ but today at work I only got up to +375 maybe it's the wall charger vs the one at home....)

Here is my OPO on my home charger. Its a Trident single dock. Ordered the dual dock for home and took the single one to work.
IMHO the Chinese docks (black or white with the wireless symbol in center and a red on and blue charging lights) aren't as great...
BTW I downgraded back to 4.4.4 since 5.0.2 was draining the phone more in idle.

I did the soldering because I wanted the USB available, but you can get the generic charger that plugs into the USB port then you put the lid over.
It's how I first started with QI on my OPO. Just make sure you get --TYPE B-- instead of --TYPE A--
Type A: narrow end of micro USB upward.
Type B: narrow end of micro USB downward (what we have on our OPO's)

Check pics. I cut off the USB plug and soldered it. But originally it was a BLUBOON generic QI charger (type b)
If you are soldering you can use TYPE A but you have to inverse + and - before soldering to the charging port.
EDIT: Attachment shows QI charging from 77% to 100% in an hour and a half. Almost 25% in 1.5 hrs. So around 6~7 hrs from 0% to 100%
