Inductive Charging

Hi!
I'm a little noobish when it comes to this and android in general so I apologize in advance
But I was wondering if there are any inductive charging pads that would work with the galaxy nexus? I've got too many cables going on on my desk right now and it would be nice to have the drop and charge type of thing going on
Any help would be nice! Thanks!

Well the Nexus has pogo pins, so I'm waiting for a pogo dock to become available.
Alternatively you could probably mod your Nexus to work with a touchstone.

That looks a litttttttle complicated for a noob like me
Would powermat or qi pad be a good idea? or would they not even work?

Powermats are great, unfortunately unless your device is a popular one, they more than likely don't make a case for it, in which case you have to use the cube that comes with the powermat to charge your device.
I'm hoping that since the Galaxy nexus will soon launch on Verizon, Powermat will design a case for it that you can just drop onto the mat.

buy one of these and modify it, someone has done this with the samsung i9000

Actually looks fairly easy with the large pin solder points. Other phones require soldering to tiny pins.
With the battery cover design, I'd be afraid I'd rip the wiring off every time I pull it open.

I've got this, after a while i'm gonna try this inductive charging, with this spare part i won't have to worry about warranty.
you can see the white dot, one wire goes their, the other will just have to touch the usim card holder, this info is just a replica of one of the links with the i9000, it should be the same.

Galaxy Nexus has the dock pins. Two of three pins are used for power supply. I think is possible to tap into those with the inductive charging stuff.
I think I'll try the 12 dollars kit from ebay . it's just too tempting.

yeh, I know, i just dont want to mess around with the soldering of the original parts, if i do mess up, i can just discard the part in the photo.

Hrm.. rather than soldering, why not use conductive tape? That way it's completely reversible should you need warranty repair.
The contact terminals look large enough for a small square of tape to easily adhere to.

Inductive case

Why isn't there an inductive case that charges the phone through the pogo pins? I know that the is a mod to do this yourself, but why isn't a professional one available?

Sounds like a great idea but it might be hard to design a case that keeps constant contact with the pogo pins without damaging them when pressure is applied to the case. Would probably have to use some spring pogo pins which would result in a pretty bulky case (on that side at least)

Didn't think of that. That might be a problem. Still, I think that gnex accessories are seriously lacking. (car dock) wtf
Sent from my Galaxy Nexus using xda premium

Actually, if it were a case, it would fit snugly enough that you wouldn't need spring loaded contacts. Any sort of metallic contact would do, however thin. I like this idea.

I saw this in another forum

I can see several problems:
Charge speed:
Without proper signalling, the pogo pins will only charge at USB rates. meaning restricted to 500mA. The phone comes with a 1 amp charger for a reason. We are just now decoding the signalling here in the forums, an IC and Voltage regulator are needed. This would make for a pretty thick case.
NFC tags:
I'm not 100% sure on this, but would think that the charging coil will block the NFC from working properly.
USB:
When the phone is charging with the pogo pins, the USB port is disabled, they are exclusive of each other. Might not be so much of a problem, but still something to keep in mind.

Charging: You would need to use a modified kernel like Franco's - not an easy sell for a company looking to mass-produce these cases.
NFC: When I did my case mod I slid the coil up a bit so about half of the battery was not blocked. The NFC works fine. NFC will NOT work while charging b/c of electrical interference, so do not put an NFC tag on your charger base.
Also, those pins are small which makes it tricky to make & keep contact with the case. I ultimately popped the back & ran 2 stripes of copper tape to the outside of the phone, covering the pins. This gave me a pair of 1/4" x 3/4" contact points. The copper tape in the case makes solid contact & life is great. The tape pieces are hidden by the case.

Wireless charging mod.

I cannot wait for the official galaxy S3 wireless charging kit to come out.
I got inspired by the Galaxy mod that was done by using parts from a Palm Touchstone cover.
ww.qianqin.de/2011/09/28/high-waf-inductive-charging-mod/
I am pretty sure, that I don't need to do an intrusive operation as the one in the link - I believe that Samsung made pins ready for it under the cover.
Does anyone know what the two 'pins' that are exposed to the left of the battery are for?
Thanks!

There are countless threads regarding the "pins", wireless charging kits, and that mod.

I have a touchstone. And a back, and would like to see if anyone has applied this to the S3 and made it work

I have a feeling the wireless charging module will interact somehow with the two pins next to the battery. I was planning on attempting this mod using these pins but without a multimeter i am unable to tell whether these pins can be used and which way round to wire them up. If anyone can assist i would be grateful.

Yes. Countless threads about the mod for the Galaxy S, but I haven't been able to find anything about pins on the Galaxy SIII.
- Maybe I'm just bad at searching, believe me I have tried!

I also would love to know if and how someone gets their sgs3 working with the palm touchstone! Hope it is not too difficult!

I have finally managed to find a page that claimt that the two pins next to the battery indeed are for wireless charging.
ww.trustedreviews.com/samsung-galaxy-s3_Mobile-Phone_review
Only problem is, I don't know Trusted Reviews - so I don't know how 'Trusted' they are?
All I need now is to find out which pin is 0V and which is +5V. (I'm pretty sure that the current is the same as the Palm cover provides.

Every accessories are always made for on pin, hdmi,wireless kit etc. Always Samsung market tactics.
I wish you'll do it.

Upper pin is plus, lower minus - and it has also be done!

Yes it works, it will be a little slower, im only seeing 450mah going in as opposed to about 1000mah
But that doesnt matter in the slightest as i mostly charge overnight

that is great news! That does not look too difficult and it looks as NFC is not touched. Just the translation is difficult and not knowing what samsung wireless charging is about.
I also wonder how snug the fit is after adding the magnets from the touchstone back cover?

I will post details soon when i am back home

I'm still waiting for my touchstone and palm battery cover to arrive...

I found this! He looks like he did a great job. I am just curious if he had to solder anything to the phone?
http://www.youtube.com/watch?v=uAqP3T_Mbzg

yes he did, i'm gonna try it with just tape - his solder blobs seems to be huge and because of the the cover makes this bulge... maybe then it will fit perfectly
the samsung wireless charger looks nice but i like the idea with the magnets of the touchstone!

please post pictures and a possible video. This is so interesting!

i'll do as soon i get the touchstone kit and have some spare time to do this (hopefully on sunday...)

what happens when you place an induction charging compatible device on an induction cooking range? Will it charge the battery, or will it overload the circuitry and destroy the phone\battery?

I wonder what happens when you plug in the phone with usb while it's inductively charging.

I would think they would work together or one would be disabled by the other. Don't think they would allow both if it could cause damage.

I'm getting roughly 15% an hour using this mod. I only use it for overnight charging works good for me. It does work through thin cases like thin tpu cases, probably not with thicker cases.
The mod was fairly basic not to complicated, got it to work first try. I have had usb ports go out on me with other phones hope this helps the life of my usb port on my phone.

Aaronkellys link goes to simple wireless charging mod.

OP,
Make sure you're using the Perseus kernel. That way your touchstone will charge your phone at 900mA instead of 500mA. And to all wondering, running the touchstone at 900mA is safe, the Galaxy Nexus crowd has been doing it for months.

Having a little trouble with wireless charging
I really want to try this but wanted to give it a go on my old phone first for practice. I busted open the old evo and read every tutorial I could find on every phone I could find. Got my leads out to the back of the phone but it just will not charge. When I have just the back on the touchstone and read it with the multimeter I get 5.6 volts. If I plug the phone into the wall charger and test the leads I get 4.4 volts. Can anyone tell me what I might be doing wrong?
Thanks

Can anyone confirmed that this information correct? I read somewhere that it limit the wireless charging to only 500mA?

I'll stick with my 2A wired charge, and only charge my phone for 2.5 hours....instead of 6.
Neat feature...but they need to bump up the ampage.

Qi Wireless Charging Pads w/ Extended batteries

Hey everyone,
I am really keen on having Qi charging and already have the pad and everything. I am looking to make the move to an extended battery (not the official one, which I hear works with the pads, but rather an ebay one, 4300mah, 4500mah etc with extended battery doors).
I know this will cause the contacts to be elevated above the spots requiring contact with the pad.
How are people overcoming this? I'd rather not solder to visible contacts inside the phone, and was curious how others have accomplished this and kept a consistent connection without permanently affixing it with solder?
Thanks!

Look for palm pre mod . It was the wireless charging mod before qi chargers were made for the s3.

I am also interested in charging the extended battery using the Qi Wireless receiver for my S3.
I purchased the recommended copper tape but had no success.
Are there steps somewhere in the forums that could show you the steps?
I do not want to solder anything to the contacts.
Thanks for your help

search this specific forum. there's a link or a thread here with a step by step.

Hi this post is a bit old, but I think very relevant today. Most tags will not work with an extended battery because of where the chip is located. I'm finding that it needs to be lower and the only ones that do that are the ones with a longer contact neck. I just purchased a 6400 ma battery and back cover for my s4... and discovered my qi I receiver tag will not work... unless I fool around with it a lot like putting a bunch of tape underneath that neck part to raise it on the short version. But with all that little bit of extra tape makes the back cover insufficiently loose because it can't snap-in because it's too thick of a battery. But I played around with a little bit as I told you above and got it to work but I couldn't keep the back cover on. So my in-enept modification failed... I read a review on Amazon or a gentleman got it to work but I notice his cute a receiver tag had the longer neck. I know the company tylt makes one, & I am calling him in the morning just to verify that is the one actally still selling.

Extended Battery + Qi Pad, Back Plate Doesn't Fit
I'm having a similar problem with my Galaxy S3 extended battery + Qi charging pad. I was able to modify the Qi charging pad to fit above the extended battery pretty easily, even though the end result is a bit kludgy. Basically I just soldered two thin wires to the contact points on the charging pad then used a piece of foam to space the wires appropriately. I wrapped this in electrical tape and tinned the ends so they'd make a solid connection to the phone contact points.
>I can't post links yet but you can see a picture of this on imgur: i.imgur.com/KJOU4I5.jpg
This worked great, except that the extended back casing that came with the battery doesn't fit properly when the Qi charging pad is inserted. The back plate that came with the battery is made of hard plastic so it won't bend leaving me with an extended battery + Qi charging but no back case. All the back plates I've seen on eBay look identical to the one I was sent. I'm going to try heating and molding the back, or perhaps sanding it down (though it's already pretty thin) but at this point I'm not super confident.
