This, cant find on google anywhere...

I tried finding compatible devices that work with the Powermat & couldn't even find that.
I do know that several people have hacked their device to work with inductive charging but it takes some major surgery and skill to get it to work.
So as of yet I'd have to say "no'

I saw a powermat kind of thing at radioshack and it says on the box works with compatible devices or need "power discs" but no one can "find" a power disc in the system or even what they look like.
would REALLY love to get wireless charging and I don't mind a little surgery

I did find something called a Duracell myGrid Power Clip, but I would rather have a case so it is pretty much "seamless"

Search inductive charging. Its in or forum
He already got it up and running but definitely takes some skill

If you do this yourself you have to be very carefull, the components are a lot more cramped than most.

So what is our best option to pester samsung and/or Google to release the 3 pin car dock? And home dock?

I know, it's pretty silly isn't it? Not only are there no accessories out that use it, but apparently from what I read the charge isn't even enough to sustain the phone while it's on. Definitely a big dropped ball. There's really no excuse for that on a flagship phone.

Seriously!
I sure thought long and hard about the Razor because Moto "Puts out" when it comes to accessories and the Lapdock looks pretty promising if they get the bugs out of the new one.
There are plenty of issues to be irritated about with this phone (flaky data connection anyone?) and I have managed to keep my disappointment tempered since with 4.0.4 coming (SOON DAMMIT!) it should solve a lot of them but thank you for reminding me of another

May I suggest waiting another 11 days for the car dock?

And... another 12 days for the home dock?

But the mounts for the GSM and CDMA versions are incompatible so... this makes no sense. Verizon can't force Samsung to not sell to the rest of the world

I made my own cradle charger out of wood just so I could have one.
It appears the POGO pins only accept max of .5A, so it charges pretty slow. I use it as my overnight charger.
If you were using a car dock with GPS running, it won't sustain it at all, given that 1A chargers barely keep up if you're running nav.
I do want to say that I am really unhappy with the lack of accessories for it as well as the fragmentation of having two galaxy nexus form factors to deal with, which further reduces the desire for 3rd party accessory makers to look at making stuff for our phone. I feel like Samsung really blew it with this one.

do we blame google or samsung? google probably gave in to verizon even though i am sure samsung has more say on accessories. so do we impale a nexus through the usb port and post it on samsung website's front page?

It's entirely Samsung, nothing to do with Google. They built the phone. Unless of course, VZ actually said - our phone has to be a different form factor, in which case they can die in a fire.
Someone at Samsung with some common sense should of said, gee golly, maybe we should just thicken up the GSM version half a mm, throw in a bigger battery and everyone would be happy.

[HMOD]Wireless Charging for home and on the go

This has already been done for the EVO 4g using Palm Touchstone capable scraps but I want to take it to another level. Since i'm not much of a programmer I can add to the community in this way.
Please let me know how many of you are interested in this. I'm going to put up full walk throughs as I move along but I will also sell some off (in the marketplace) for those that don't want to go through the hassle. I'm going to start ordering parts and building mock-ups and doing some design work during slow downs at work. I'll have a donation link up eventually if any one wants to help cover the initial costs.
-----------------------------------------------------------------------------
CURRENT DEVELOPMENT STAGE: 1- INDUCTIVE CASE RESEARCH, see #1​
PLEASE KEEP AN EYE ON THIS POST (general updates) AND POST#3 (useful links and eventually tutorial)
:good:KEEP DISCUSSION AROUND THE FOLLOWING DESIGN INTENTIONS/ ABOVE DEVELOPMENT STAGE:good:
Design Intents are as follows:
1) A case for housing the inductive coil/wiring
This just requires compatible cases with necessary clearance for the inductive coil and wiring to the male micro usb. Cases with oversized bumpers would be best since they will keep drops from damaging the micro usb plug that will be sticking out of the bottom of the phone. This may not be ideal so if anyone is decent and making plastic molds maybe we could come up with an attachment to a case.
2)NO Hard wiring inside/to the phone
This involves using low profile male mirco USB type B connectors, like this, and mounting and wiring to the case. This will keep your plug always covered and keep you from trying to charge your phone with both inductive and regular usb to the wall/pc. The main design issue here is protecting the male connector to the phone. Suggest usb connectors, wiring, how to boost the amperage, does the palm pre coil protect from over voltage, etc.
3)A car kit.
I will start with my car, A nissan sentra SR, for the car kit. Others are encouraged to come up/share your solutions as well! This should be a hard wired solution using the palm pre/pixi round touchstone dock. Kind of like a dash mount. I think the magnet should hold the phone ok being that my car isn't one of the most powerful things on the planet but for you hot rodders out there keep that possible issue in mind.
----------------------------------------------------------------------------
----------------------------------------------------------------------------
Current Progress: CASE​Alright I have the cases in hand! I got three of them in the mail and will be tearing these apart this weekend. The pucks (touchstone bases) should be here sometime next week.
I'm also looking at the following cases
Ballistic
Ballistic 2
Clear S Case
The ballistic I am hoping will give clearance for the micro usb. They will be a bit heavier though... we'll see.
I going to order 2 cases for starters, what should they be?

Regarding the thread, this would be hardware development which i believe belongs in the general section. As for the idea, it seems like as long as its not too bulky most users wouldn't mind if it extended battery life substantially like 24 hours or more. Could make you rich with over 9.million sgsIII owners. But Im pretty sure there are already many types of chargers on the market so unless i missed something perhaps you should submit this to a patent office so no one steals the idea or design. Just my two cents dinner no one else has posted. But ya not software development so I would move three thread before you get flamed too bad.

I'm game! I tried doing it myself but I could only find the one spot on the USB plug to hook up to. I opted but to do it because there was some massive dismantling and soldering I would've had to do. I've still got the parts ready for when someone smarter than me figures out an easier way to do it though!

Just a thought.
What would be the charging time using touchstone/conductive charging; or in other words, what would be the output voltage/current provided to the phone. It takes a while on regular chargers to charge the phone compared to HTC phones.

haha I actually did this too my I500. Literally car kit and everything. Even had it play music through Bluetooth. except I hated cases on that phone so I hardwired it. looked so much sexier. But the case is easier. Built like that too just didn't have the car cradle

I have 2 palm touchstones, 2 old fried pre & pre2, and 2 phone backs for the touchstone charger to integrate with the phone..
I would absolutely love to know how to integrate the "guts" of the battery cover with the needed parts into the e4gt innards to make the wireless charger .. but I'm not sure how yet.. :/ I will keep reading and post here if I get it working..
I assume that the physical connection is totally possible but the OS will most likely need to be able to control voltage and jazz so I'm not sure what would be needed for that part..

Thanks for all the interest and offers for assistance. Being that its my friend's birthday as well as my own on top of fathers day weekend I won't start any design research until Monday.
I have ordered some parts which should be here late next week. I am still trying to find a source for some type B micro USB plugs. Guess I'll shoud stop throwing away those electronic component magazines. I did a quick search and found some but they were $6.50 each with $10 shipping. If any of you have a source for these let me know. Hell you can send me spare cables and I'll deconstruct them if I have to, but that's not very fun.
When I get on my PC I'll add a poll to see where you all would like this topic to be. Then I'll ask you how do I move it

Lets do it!
I actually got the touchstone and pre back and ripped out the inductive charging circuit just for this (I actually got it for my evo, but I upgraded before I had the chance to follow the evo guide). I'm excited for this!
Anyway - some heads up - the E4GT is MUCH heavier and bigger than the pre. Don't expect it to stay firmly attached. It will stay okay, but you need a really thin back face of the case. You may also try replacing the thin magnets with thicker rare earths. I actually got it under the stock cover okay, and that worked decently, but no good way to attach it. That's where I quit (after thinking about soldering to the board, but not having a good place on the USB connector without taking the phone all of the way apart. I also didn't fins another point on the board to solder to (like the charging circuit), although I'm sure it's there somewhere.
Also, you need to mount the inductive charging circuit a little low because the phone is so long that it will hit the table and not mount properly if you put it in the middle. Furthermore, be ware that if you add a connector to the USB port, this will exacerbate this problem, perhaps to the point of requiring landscape or stronger magnets.
The USB connector you want are available at a number of places. Ebay has some cheap micro usb adapters (including right angle) that you might play with. If you just want the connector itself, it will likely be more expensive, but I suggest checking mouser or digikey.
Good luck! This will be AWESOME!

So please keep this in mind while you discuss it. Have a good time guys!

I'd like to start it off with a wireless charging kit I purchased that comes with a receiver and transmitter.
The manufacturer is called Yijieneng.
The receiver fits underneath the battery door with no modification required.
From what I've noticed about it, it charges a little faster than USB but not as fast as an AC adapter. (according to the receiver, it charges at 700mAh)
NFC works with this kit.
As far as I've noticed, the range is about 4mm (from transmitter surface to battery case) for there to be a successful charge.
The transmitter emits a small beep when it starts the charge. I've had it next to my bed for the past few weeks and I don't hear it when I sleep if it goes off. It does keep my phone at 100% in the morning.
At this time I'm also creating a custom dock that will put the phone up at an angle like a dock. I have finished the core part of it, but still waiting to finalize the ridge that will hold the phone. I'm waiting to get a certain bumper case before I create the final ridge.
Here's a few pictures of the dock in its current form (it still needs to be sanded and have the surface reworked):
https://www.dropbox.com/sh/4bcgiapslrawvcs/yIOWW5Fybz#/
Here's a video of the kit that I shot showing how it works as well as NFC function.

As far as I know, the charging distance is between 4mm to 4cm (if the transmitter is based off the newer standard)
Charging speed
Depending on the receiver it can range from 500ma to 700ma (this is roughly the speed of usb charging or a little faster)
Does NFC Work?
I can't vouch for ALL the Qi kits out there, but the Yijieneng one that I do posses, works. Reference the above video to show that it works.

Yijieneng kit. Comes with a receiver pad that fits underneath the battery door and a transmitter.
Warning: I highly suggest getting just the receiver pad from them rather than the whole kit. Apparently the 2nd version seem to be problematic and requires an exact placement. You can find the transmitter at your local phone store like AT&T and Verizon or get it from sites like Amazon and such for the Energizer Qi charging pad.
As for those who are asking how to purchase this, this is what some of the members have done.

EDIT: Added some extra info
EDIT 2: There are many members who have asked me where I got this kit from and the best I can and am allowed to disclose is that you would have to look up the manufacturer and contact them yourself. As far as I was reading, various members have actually directly contacted the manufacturer through their website and did their own transaction there. I personally have not done it before so I can not guarantee anything. I also do not know how much they charge nor do I know what kind of payment they take so your best bet is to talk to them. I only have this one kit that I have shown in the video and no it will not be sold to anyone (I like it too much and use it too much for me to even think about giving it up)

I'm such a sucker for stuff like this. But I have a hard time spending what looks like 85 for the pad and receiver for something that I most likely won't be able to use on my next device. This would be high on my list if I was capable of keeping a phone for over a year! :silly:

The charging base can be used for other qi compatible phone, so it's not a waste, while the receiver, it can be modded to support other phones.

Absolutely valid points. However I think I'll let the technology mature and adoption to increase a bit more. I'm sure prices will drop drastically.

Just wanted to post a walkthrough video of the Droidax EzyCharge Wireless Charging kit. I'm really considering opening the case up and seeing what kind of receiver is inside and possibly fitting it under the back of my phone and if I do it I'll update this post. Otherwise, I think its a great 3-purpose combo (case, wireless charger and backup battery) especially for the price when compared to the competition. The pad can be sold seperately and charges any device thats Qi compatible so thats always a plus. If anyone finds a cheap and slim Qi receiver being sold stateside let me know I really want to get a couple. Thanks!

Absolutely valid points. However I think I'll let the technology mature and adoption to increase a bit more. I'm sure prices will drop drastically.

The technology is already actively used in Japan, but it has yet to receive a wider audience. Some phones also come built in with with Qi wireless charging like the Droid DNA and the Lumia 920. Hopefully there will be more and more devices that have it built in and then hopefully the "battery covers" for those phones will be sold on sites like amazon or ebay that comes w/ the qi receiver that you can remove and mod into the s3..

I also have the kit in the first post. I like it well enough. I use it at work all day. I am having an issue where I cannot receive phone calls while charging on the pad. Anyone else experience this? I have the leaked jelly bean k1 build. Just stock leak. No mods. Any ideas?

i get calls all the time even while it's charging (especially those damn telemarketers) .. i can take a ss later of my screen when I have it in the base.

I actually tested this out on the S3 and note 2, both on stock kies updated, everything works fine except you cannot use speaker phone.
SMS send/receive ok,
call in/out ok,
BT call in/out ok,
handfree in/out ok,
speaker phone other party ok, phone on charger too much loud reoccuring echo.
someone else also mention this, he was also on custom rom, so it seems like custom rom may affect the functionality.

Dose it matter what charging pad I use? seems like you can get a back plate off ebay for $16 but dont want to spend the 50 on a QI pad.
so Can I just get any charging pad or dose it have to be the QI to work or are they just universal?

If the backplate is a Qi compatible backplate, then yes it will work. If you're talking about the palm touchstone mod, then no. They operate on a different frequency.
This applies to all the different standards. As far as I've read, no standard are intercompatible with the other.
i.e: Qi will not work with Touchstone or Powermat. Powermat will not work with Qi or Touchstone. Touchstone will not work with Qi or Powermat.
They send out a different set of frequencies that the other standard does not use/accept.

thanks. that kinda sucks because they sell the other powermat for $10 bucks but QI is 50.ill have to check out the frequency it uses and see if I can find an alternative.

I remembered that Powermat claimed it will work with Qi back in early/mid 2011, but doing a search has shown me nothing. If you order from amazon, you can probably try the powermat transmitter and see if it works, then return it if it doesn't, but I highly doubt it considering they're competing standards.

I'd love it if Samsung came out with a Qi charging kit since it seems to work so well but at this point I'd be happy with anything from them.

samsung is too busy flip flopping between 2 different standards. the contact points are there, you should be able to purchase a zens or yijieneng receiver and get a cheap transmitter from energizer or something.

Very cool. I wonder what the charging pad looks like.
Also, while this will fit under your otterbox I don't know if it will actually charge it through it. Worth the $45 though!

for 45$ and a drop in solution i am willing to try and test it...

This looks like a damn good price tbh. $68 for a receiver and charger is cheaper than any qi combo that I know of currently.
The bonus is that it's also Qi technology so even if you change your s3 out, you should be able to get another phone that has qi tech in it or even modify that charging pad to work on other electronic devices (with some copper tape/wire)

Thats exactly what i was thinking.. The odd fact that i just so happend to find this today and apparently it just went live today i am pretty excited to snag it at this price.
But As im sure the capabilities to wirelessly charge are inevitably going to be included in future phones it isnt like this tech is likely going to be easily replaced. And it also seems like Samsung is going to abandon using our phones tech as wireless charging.. or at least thats what i gathered from thsi article..
http://www.theregister.co.uk/2013/03/11/samsung_s4/

the thing w/ samsung and wireless charging is that they really have no idea who the hell they're really going to back. Yes, Samsung co-founded A4WP, but they're also member of Qi's group as well.
To me, it just looks like they're sitting on the fence and waiting to see who will come out as the standard before going all in. I also don't think Samsung will build it into the phone itself due to its current ambivalence on the 2 standards and most likely leave it open like the s3 and note 2.
While the article talks about a4wp having a few cm of range, he also did not mention that a newer revision of Qi offers up to 4cm of range as well (last I checked).
I don't care much for too much range for wireless charging, just enough so that any non-ferrous case will charge regardless of thickness. I have a Qi set and it has so far worked with the ballisitc SG (although it Can get picky, but that's due to the fact that I also modified the charger to be at a 45 degree angle and the case's bottom lip [on the hard plastic side] curved up a little for no reason)

Right that much i understand...
I was holding out for the wireless charging where i didnt need to have it directly on the base. and every few months i search around for a viable option.
So far, since my free time is limited, this seems like the best all in one solution that doesnt require me to change my case, and its a good price.

in you case it seems to be a cheaper and more reliable solution imo.
all in all, it's a good find. although I should've ask if it affects nfc as well..

The stealth one, and the one built into a battery cover can be found on a different site for only about $15.

this one comes with a charger as well.. which would cost 50-60 usd more. so it's a good deal.
Sent from my GT-I9300 using xda app-developers app

Well.. I bought mine for $47.90 with the charger and receiver, so if your willing to spend just another $2 then you can get that with less of the wait.

that's great. any link for others who might be interested?

Hm.. I like how there is radio silence as soon as there is a mention of link to provide proof.....

I wonder if the smart one works with those thin protective cases?

That was for Tenchuboy, not you.
He claimed he got a set that was cheaper and all that, so I asked a link so he can prove it. So far, complete silence from him.

OOOhhhhhhh....
i got it. i know i could make a set with the palm pixie stuff, i priced it out on amazon and total with a charging dock its like 20$... but i dont have the time to. im only actually home about 3 days a month. id rather be lazy..

Just an FYI i got my wireless charging kit from this company and it works great. Its a small device that attaches to the back of the stock battery. Its very small and it fits perfectly, very small buldge from the device but the back case fits on fine and my otterbox fits it perfectly.
the best part, it works with the stock otterbox. there were no issues with wireless charging whatsoever.

How is this one any different than any of the other wireless IQ receiver pads & chargers for the s3?

That it works with all variants, doesnt require you to change out your battery door, although they offer a solution for it, and its pad and reciever for 40$
