The two contacts by the sim card are for the NFC antenna -
they line up with the contacts on the back of the phone.
What are the two on the right of the battery? Wireless charging?
I'd really like wireless charging actually. My USB port is a bit wonky on my Note 1.

NFC is built into the battery. Like the nexus and S3. Two pins are going to be for wireless charging, the other two I'm not sure about. Diagnostics maybe?

This was changed for the Note 2.

See the text below the picture of the battery:
The back peels off just like the Galaxy S III. You can see the massive, 3100mAh battery, and the microSD and SIM slots. Previous NFC Samsung designs, like the Galaxy Nexus and GSIII, put the NFC antenna in the battery, but here the antenna is built into the removable back, and there's a set of gold contacts connecting it to the phone.

I'm glad the nfc chip is not in the battery anymore, now we can go and buy third party spare batteries without having to worry about the nfc.

So after ordering two 1900mah spare batteries from ebay I found out that the antenna for the NFC chip is located in the battery. The replacement batteries I ordered do not have the antenna, neither do any of the other batteries I've seen. So I went to the source Samsung.com and they aren't available for the GSM version only the Verizon version batteries were being sold. So where do I find a GSM extended battery? Or any battery with the NFC antenna inside? As for the batteries I ordered? I guess they'd be fine in a jam but to lose features like beam & NFC is unacceptable for the long haul. All feedback is much appreciated.

A seller named shimshop on eBay is selling 2000mah extended batteries that are genuine Samsung, with NFC. There are many threads mentioning this. I bought one as well.

here's the link,
http://www.ebay.com/itm/12083246205...NX:IT&_trksid=p3984.m1497.l2649#ht_4968wt_905

Something to consider is switching over to external USB batteries. Not only are internal batteries phone-specific (and obviously have NFC issues with the Galaxy Nexus), but there is an increasing trend towards using polymer batteries that are able to fit in unusual shapes but are not user-replaceable (easily). I've got a pair of APC UPB10s. They work with all four phones my wife and I carry, as well as my Bluetooth headset, a host of other devices, and I've got an adapter that lets me use it on my infant daughter's bouncer and swing. I can also carry it in my pocket without a cover (or fear my keys will short it out), I charge it via a mini-USB port (micro would be better, but I don't need a battery charger), and it has a 10,000mAH capacity compared to a spare battery running on the order of 2000mAH. The only downside is that if I'm out of juice I become tethered to it until I can recharge, but a little pre-planning lets me charge in my pocket and it still beats needing to power off my phone just to swap a battery.
Just something to think about instead of dropping more money on batteries you'll end up throwing away when you upgrade your phone.
I actually have three oem samsung batteries, 2 standard and 1 extended, and 1 third party brand at 1450mAh, i've also ordered, but not yet received yet a powerocks 7800mAh external battery.
i wont even need to change out the extended battery, or even use the external, so I dont know why i have all these.
Hey guys, I just want to know if u could take out the nfc antenna from a stock battery to put into another battery. Like a Seidio or any eBay battery?
Send, Finally From Lte Galaxy Nexus
No. Official NFC batteries have 4 pins (1 dedicated to the NFC in addition to the antenna). The fake/eBay batteries have only 3 pins. Just buy an official Sammy battery if you care for NFC.
Hey guys, don't know if people have done this already, but I just got a T-mobile S4 for testing this weekend and I wanted to find out if the wireless charging port was enabled since I've done the touchstone wireless charging mod on my S3 and note 2.
It was especially a PIA on the note 2 since T-mobile, in all of its corporate and engineering wisdom, decided to disable the feature for the Note 2, even though it was enabled for the S3. So for those of you who don't like to dissemble your new phone and solder on a tiny PCB, you'll be happy to know that I confirmed that wireless charging ports on the S4 is indeed enabled.
I took a pack of 4x AAA battery assembly, which provides ~4.7v of DC power, and connected to the charging port in the back. The small pair on the left is the charging port, the pair on the right is supposedly NFC, even though the NFC antenna is located on the battery for S4.
As you can see from the pics, the "the phone is now charging wirelessly" notification pops up when the circuit is live, which is pretty annoying IMO and can't be disabled (that's why we have custom roms right?)
I haven't gotten a chance to install the actual touchstone wireless charging receivers on the back yet, as this is a test unit that I have to return, but I don't imagine this to be too different than on the S3. There will be a slight bulge, but it'll be worth it.

Just follow the instructions from this thread (it's for an S3). The design for S3 is pretty similar, so it should work. Remember the positive pin is on the left, negative (ground) is on the right.
Also note that the touchstone mechanism is not Qi compatible, so it wont work with the newer charging mats for Nokia or HTC.
And always remember to perform these mods at your own risk.

Did you install any receiver on the S4?
I didn't mean to confuse anyone, I only confirmed that it is POSSIBLE to perform the mod. I used a 4.7v DC power supply to test if the wireless charging pins on the back are live, which wasn't the case for T-mobile note 2 so I had to check to make sure.
If you already have a Qi charger, you can get one of these receivers and connect it to your phone, then you'll be able to charger with your mat
http://www.ebay.com/itm/qi-Wireless...l_Phone_PDA_Chargers&var=&hash=item51abef6de9
But I would argue that the touchstone method is superior to qi if you plan on using it in a car, as the magnets keep the phone in place is it's really convenient to connect/disconnect when you're driving.

Samsung will be officially supporting wireless charging for the S4 through accessories. The ad for the pad and back wireless charging cover is already listed on the promo S4 accessories page. http://www.samsung.com/global/microsite/galaxys4/
Though there seems to be no price or date yet.
Of course there will be 3rd party wireless charging solutions as well.
ive got a palm touchstone but what receiver do i need to buy to have my GS4 work with it ?
also;
can anyone confirm or deny wether or not the palm touchstone + receiver will trickle charge the GS4 after it is fully charged ? (or does it completely cease charging until the phone is physically picked up and replaced ?)

Took the Qi wireless receiver pad from my Galaxy S3, had to slightly tear it apart to reverse the little gold inserts that create the contact points for the wireless battery charging and now have a fully functioning wireless charging Galaxy S4 !
Saved myself quite a bit of money doing that.

It seriously only took 5~10 minutes once I'd figured out which way to put what.
I have the photos set up and just need to put notes on them explaining what I did.

Ummmm, from everything I read the pins you have it hooked up to are NOT the ones for inductive charging, the gold ones on the right are......
I could be mistaken however. I remember the s3 used those pins, but I've read in a couple places that the ones made specifically for inductive charging are the ones on the right above the battery.

What ARE all the other pins back there for? I figured one set (had no idea which one) was for inductive charging, but couldn't figure a reason for the others..

the smaller set is wireless charging, the larger set is presumably for additional NFC antenna (although I measured no resistance in the circuit with my voltmeter), as the back cover seemed to have a carved out area for a NFC like the Note 2 did.
Although the S4 battery says "NFC" on it, which seems like samsung made a last minute decision to put NFC on the battery instead of the back cover... oh samsung ¯\_(ツ)_/¯

Nope, the NFC is in fact in the battery, the same way Samsung has been doing it for years now. They made no change.

Are the two gold points on the plastic back of the Note 2 for NFC connectivity and if so, why doesn't the S3 have them there as well?
I believe they are there for wireless charging.

Our phone needs NFC antenna for the NFC chip to work,
In NOTE 2 - It is in the back-door, and
In Galaxy S3 it is embedded in the battery
Advantage - Note 2 : Unlike S3, you can use cheaper batteries in Note 2 that do not have (/need) NFC antenna like Anker.

The NFC antenna actually is the one that is embedded in the battery (and as well as the back-door in the Note2). The hardware is deep inside!
The antenna receives the signal and passes it to the hardware, probably it explains why S3 has 4 contact terminals, while Note 2 has only 3 terminals in its battery (because it uses gold pins next to the SIM dock! (while the one near battery dock is for wireless charging)
The zerolemon battery covers the standard pinouts to the QI wireless receiver for wireless charging. Does anyone have a solution, workaround, modification or source for a QI receiver that would work? It is so convenient just to put a phone on a stand and top it off, even with the massive 10,000 mah battery. I am NOT interested in anything that involves soldering anything to my precious phone, or modifying the phone in any way, just the receiver. Thank you in advance for any thoughts!

Maybe one of these cheap charging pads can be modified instead of your phone? They dont seem to have one specifically for the note 4 yet on here, but for $6 thats a pricetag you dont have to cringse about when you srtart soldering on it..

Hope it helps.
Basically you have to extend the contacts from the phone back. You don't need to solder. You can do it with double stick foam tape, masking tape, adhesive copper braid or sheeting and the adapter. My adapter has not arrived yet so I am not sure it will fit between the Zerolemon battery and the case back. I did something similar to get NFC working with my Zerolemon on my Note 2. Once my adapter gets here I will report if I am successful and the fix is safe and dependable.

Don't Modify Anything
Instead of modifying things just use this simple device available on Amazon. Make sure the output matches the requirements of your device before you purchase or it will not work. This is the one I purchased for use with my LG G3 and the ZeroLemon case with the extended battery and it works just fine. You still do not get the NFC capability, but the wireless charging works. But then who actually uses the NFC anyway?
Just search on amazon for micro USB Qi antenna or wireless charging antenna. (the forum won't let me post the link)
This adapter is very easy to install and adds the Wireless Charging / Qi charging back to your phone. Amazon has several versions, just make sure you get the one that has the correct configuration on the plug, either small side up or small side down, and you also need to make sure you get the one with the correct output. For the Lg G3 it is the one with small side down, 5v-1000ma output to make it work properly.

The Zerolemon battery covers the ports, making the standard Qi receivers not able to attach to them, that's why we need a different solution.

Actually, that is not true. I have installed the exact item I was talking about, and it works perfectly fine. The cover over the port does not fit "air tight" over the port and has plenty of room for the adapter to fit between the cover and the phone. This is why I had suggested the item in the post.

The Note 4 Qi contacts are in 2 places. The upper one, just to the side of the camera, is not covered by the Zerolemon Battery, and does not pose a problem for connecting, but the one next to the battery IS completely covered by the battery itself. Maybe I'm missing something? I don't care about NFC, but would really like the Qi charging feature. If you know of an item that would work, please PM me a link. Thanks!

Not for a Note 4, different contacts (won't work).
I really thought I was in the G3 forum...sorry about that.
They make a qi receiver now that plugs in the charger port of the phone and then flips back to the battery door it's on amazon like 15 bucks. Place case over it to protect receiver and phone any your good to go. I'm sure this will work just fine for ya there a universal qi receiver for tablets and phones with no battery door.
Here is a pic for you.
