Genuine Samsung 1650mAh batteries are only $30 at an AT&T store--$15 if you have corporate accessory discount.
Picked one up for my i9100, seems to fit okay and everything seems to work ok.
After searching, i could find that some people are using the NFC batteries (either from the i777 or the Korean NFC GS2).
Has anyone experienced any detrimental side effects to using the NFC batteries in a non-NFC equipped i9100?
Is there any risk for that matter w/ using an NFC battery for our i9100's?

I've been using one for four months now, only issue for me is that the battery cover creaks a bit more when the NFC battery is used, and the usual issue that happens when swapping batteries, your charge information is less precise at the bottom of the scale.
This thread got me thinking, if one inserts the NFC capable battery from the at&t Mobility SGS2 into a GT-I9100 would it provide the same NFC capability that it provides to the at&t version?

Nope, people have been working on it, but nothing seems to work so far, the battery only has the aerial in it anyway so you need the software and for the chip to be wired up correctly.

Now that i have your attention........i was playing around on play.google and i found an nfc program that will allow you to repurpose an old nfc tag...well i got to a-thinkin...., my kids have the game "skylanders" for the wii and computer... now if you dont know what skylanders is, it is a video game with NFC figurines that have special powers. You place the figures on a NFC reader called the "portal of power"...moving on. i was thinking "hmm....i was not able to read these before, so i wonder with this program can i read these figurines. Now mind you i had installed an inductive coil into the battery cover of my phone...I installed the program and grabbed one of the figurines and low-and-behold IT WORKS!!!!! the inductive coil does not interfere with the NFC coil....just thought y'all wanted to know...

Thats cool. Any pics of how you have the coil on your cover? Stock back cover?
^this
yeah its the stock battery cover, and i just taped it on with good ol' fashion electrical tape. i believe in my other thread i show the inside of the back cover and the out side of it.
On a side note, were you able to read them? I've been using NFC TagInfo and am 0 for 5 trying to scan various things that I know have NFC/ RFID.
Lol spyro???
And it would be cool to have an rfid reader for the phone

Pretty cool. But there still missing a magnetic plate in the S3. Therefore, wireless charging won't work. Unless you DIY yourself.
The S3 has an optional wireless charging battery door - and it uses the same Qi tech as Nokia, so it should work just fine. The NFC part may not be as easy, but the Tagstand tasker could solve that too.
I very much doubt any NFC stuff will work. It uses proprietary tag formats.

There is another Nokia NFC speaker http://www.amazon.co.uk/Nokia-Unive...rround/dp/B005LBCFCE/ref=cm_cr_pr_product_top
One of the comments on there says now with Android Jelly Bean it works natively. However even if it didn't in this article it also describes how using a couple of apps you can make it work http://anders.tonfeldt.se/?p=1392
Get wireless speakers/headphones and put an NFC sticker on them.
Get a wireless charging matt and put an NFC sticker on it.
Probably a lot cheaper than what Nokia will want for a novelty product with NFC already included.
I have a Samsung Galaxy S3 which depends on the battery with a built in NFC antenna for NFC to work. I am currently using a 3rd party battery that doesn't have an NFC antenna. I would love if there is an option to somehow add an antenna externally, but not through the use of a microSD card if possible. Does anyone have any suggestions? Thanks!
Doubt it. NFC isn't just a matter of adding an antenna afaik.

It would be really be more feasible to just buy a different battery with NFC support. Trying to add an NFC antenna to the phone would be a lot more work than it's worth.

I assumed the rest of the required hardware is built into the phone and just the antenna in the battery, but then again the antenna probably needs to receive power so I can see how that would be an issue. Thanks for your input.

Actually on the SGS3 the NFC antenna is in the battery, not the phone.

Actually I knew that since it was stated in the first post. I consider that still inside the phone.
I thought the user I answered to imagined something like this here as an nfc antenna.
While technically yes, you could make an antenna out of say aluminium foil if you could figure how to cut it so you end up with a tuned antenna, then connect it to the correct pin on the battery connector, I think any sane person would just stick an NFC battery in.
I think they put the antenna in the battery because it's up close to the back of the case. That would also keep it well away from the other antennas that I doubt would like the power pulses that NFC puts out while it's polling.
Oh and Damastus, that picture it hilarious.
I've done the wireless charging mod using Palm Pixi guts. That thin coil of wire is enough to break NFC communication, depending on where it's put. NFC has a VERY short range, so I'm sure it's in the battery to put it as close to potential NFC chips you want to read, and to minimize anything else getting between the antenna & chip (like cases, batteries, etc.)

On the Nexus S, the antenna is built into the phone's backplate.
In theory, you could buy a Nexus S back, remove that antenna, and put it on the inside of your phone.
Run fine wires from the phone's NFC antenna connections to the antenna, and it might just work.
I'd expect reception to be lousy, since you'll detune the antenna by trying to connect it. This also assumes that the NFC circuitry is in the phone, and the battery has only the antenna.

I got my extended battery (4300mAh) with NFC support from a Chinese manufacturer for only $15. I know you have to be careful with those, but this one seemed legit so I took a chance and it works great - last forever - AND has NFC. Here's the one I got: http://www.aliexpress.com/item/NFC-Extended-cell-phone-battery-with-cover-for-Samsung-Galaxy-S3-I9300-4300mAh/577969392.html
just take apart an OEM battery and start playing with it. My guess is what you want to do is VERY doable.
If I recall correctly, the Verizon SGS3 inductive charging back cover has the NFC element on the cover, not the battery.

I think you're right, however I'm pretty sure that's what the extra two pins under the battery are for. These pins are only on the Verizon version of the GS3 though, so it wouldn't work for my T-Mobile GS3. Thanks for the suggestion though.
buy a cheapy chinese battery that has NFC and "have at it"
As far as I have known, there is a type of NFC antenna available in the market that can be stuck to the back cover of your Galaxy S3. In this way, you can take full advantages of NFC functions of the Samsung mobile with an alternative mobile battery. However, it seems that most providers like Sunshine Good Electronics Company only do wholesales business on platforms like Globe Resources. You can search it on e-bay, maybe you will be surprised to find on retail seller.
Hey everyone,
First time post but I have a question I think others might be interested in as well. I'd like to create a simple method of charging my phone wirelessly in my vehicle but I have a few questions before I make a couple purchases.
1.)Will the LG WCP-300 charge through a galaxy s4 otterbox defender case?
2.) Will the Samsung Wireless Charging Back Cover be able to work with my galaxy s4 otterbox defender case (perhaps with a little pressure applied)? I've seen a post online where a user was able to get it to work. Anybody on XDA try it out?
3.)If I stuck a NFC tag on the LG WCP-300, will wireless charging still work fine? Will NFC work fine?
4.) Will the LG WCP-300 charge my phone if I have it plugged into the Pioneer DEH-X6500BT USB port? I know it may not charge quickly, but what I'm leaning towards is having GPS, bluetooth, NFC and music streaming from spotify while having the battery charge at least not decrease, or have it decrease slower.
5.) Will the NFC tag work through my galaxy s4 otterbox defender case and Samsung Wirless Charging Back Cover?
I've heard of the OwlPad, but the reason I don't want to use that particular setup is because I'm trying to cut down on the amount of cables running in my car (the reason I'm going wireless, and I've got a radar detector already hooked up and don't want to use a cigarette lighter socket adapter to run two gadgets). I know a cigarette lighter socket adapter might be able to charge it quicker, but if the USB port can provide enough power to at least keep the battery from draining while running GPS, bluetooth, NFC and music streaming from spotify, then I prefer that route. I'd also like to stick to the products mentioned since I'm kinda trying to avoid third party products.
Thank's in advance, and looking forward to hear back.
Thought I would add my findings encase anybody else has similar ideas they want to undertake!
1.) I can confirm the LG WCP-300 charges through the Otterbox defender case for my Galaxy S4.
2.)The samsung wireless charging back cover (by samsung for the galaxy s4, no third party) does indeed fit with the otterbox defender case for the galaxy s4. It fit it 100% okay, but you will feel a bit more weight and notice a difference. It feels like more girth, although it locks into place and has not came apart. I will warn that it is a snug fit, so if it doesn't work for you the first time, keep at it. It doesn't bulge, but you just gotta see it to know what im talking about, I'd say give it a shot. I found a half off accessory code online and bought it directly from samsung.
3.) have not tried a NFC chip on the wireless charger yet.
4.)The LG WCP-300 does work with the pioneer USB port. But be warned!! I thought the USB port wasn't going to work (10 foot cable is recommended if you want to run the cable and try hiding it, that's what I did), because the wireless pad didn't work on my first attempt. Gave up, brought it inside to use. The USB cable inside didn't work. I had tested it before, and it did work. Odd.... Turns out, a good amount of the USB cables have to much plastic near the micro USB head which prevent the cable from going into the wireless charger all the way. Shaved some of the plastic on the cable in my car and.....got it to work. Wireless charging working in the vehicle via USB port.
5.)NFC does work through the case. Tried it with a Nexus 7 tablet and communications worked as long as it sat at the sweet spot (which I'm sure is fairly standard).
The next step for me is fallowing the guide to root the phone (thanks XDA community!!) and then fallow a different users guide on xda (Sorry, I'd post links and directly link but I haven't reached the post limit to do so quite yet) to allow unlock the phone via NFC while the phone is locked and the screen is off.
NFC running 24/7-->Place on Wireless charger with NFC chip-->Unlocks phone, sets it to not turn the screen off, turns off wifi, turns on bluetooth and connects to receiver, and starts spotify. Remove phone from NFC and all settings revert back.
Will post back (or create new post?) when it's all accomplished, maybe a video if people are interested??
I'm interested in pictures, sounds like a neat idea.

The NFC will only read the chip so long as to enable the mode. It does not act as a proximity sensor and will not "revert" back to it's normal operation. Keeping an NFC chip in range the phone will ignore it after it first reads it. You will either need NFC Tasker or some other app to make it a "switching" tag where you can lift your phone off, tap it again to return to normal mode and then go on your way, or another tag stuck somewhere else to trigger going back to normal, maybe perhaps on the car keys?
Yes the post that talks about unlocking the phone has tasker involved with reverting the settings back. On another post it mentions unlocking the phone by keeping NFC on 24/7. The app I'm looking at is NFC Unlocking by MohammadAG, and work also done by Madfish73.

Ultimate rotation control worked great for my galaxy s1, but the s4 is a little buggy. Nova launcher works great for the homescreen rotation, but the lockscreen rotation is absent in nova launcher. Looking to have both rotate.

NFC unlock works perfectly fine. I don't think you understood what I was saying, the NFC system triggers once per touch to the tag, and that's it. You can leave NFC on 24/7, all it will do is waste just a tiny bit of battery each hour throughout the day. When you touch the tag (on your wireless charger in this case), it will trigger once to unlock and do all the things you want it to do, but when you remove the phone, it will do NOTHING. NFC does not care when the tag has been removed from it's field, just the initial connection to exchange data, that's it. NFC is a fire-and-forget-it system, it does not track anything other than the initial touch. It will not work to pull the phone away and "viola, locked and normal again," it just doesn't work that way, you'll either need NFC Tasker or some other app to create a switching tag (so you tap it again to 'switch' back to normal), OR configure another tag say on your keys to lock the phone and return it to normal.

Did the second link I provided above not run special actions when NFC is removed (I think you're thinking of a different method...)? I fallowed the link from a site, Google "Lifehacker Run an Action When You Remove Your Phone from an NFC Tag" and it should show what I'm talking about. Yes, I am FULLY aware when you remove your phone from a NFC tag, it doesn't run a task because the tag is braindead, and only does what it's programmed too. Hence, you need your phone to say "Hey, I was removed from my NFC tag, let me run another special command!" via special applications that would signal the phone to do so. The reason I want NFC running 24/7 (even while the phone is locked, normally it has to be unlocked to accept a NFC command) is because its convenient not to unlock my phone to run said task (I belive the Moto X has a similar feature with the Motorola Skip). I know i could double tap the NFC tag to revert settings back (via, again, a app), but its not as seamless as just removing it and going on my merry way.
I'm just trying to ace this in one go around, but seeing as phase 1 of my ongoing saga is accomplished in this post, I think I'll create a new post so the title can attract some more help. Thanks guys! And Exel i will do one better and post a video. I'll try to remember to send it over to demonstrate my methods, but only once I'm satisfied with the results :good: .

Second link on review appears to have some solid tools and tweaks to accomplish this goal successfully. I look forward to seeing the results, I know one friend that would probably go for this in a heartbeat.
Try Llama. Not the easiest UI to get on with, but very powerful and free.
You could use a llama variable and 'removed from wireless charger' condition to know that it was removed from the NFC: 1) when NFC tag comes on, set a llama variable. 2) when removed from charger and llama variable is set, do whatever you need (including reverting the variable). If that's the only wireless charger you use, then you don't even need to use any llama variable.
Among other things, I use Llama to deactivate pattern lock when connected to home wifi, and activating it when disconnected from home wifi after a certain delay. This could be done with many apps of course (Tasker, AutomateIt, etc).
