http://st3.gsmarena.com/pic/vv/reviewsimg/samsung-galaxy-note-ii/preview/phone/gsmarena_015.jpg
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:

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.

Which is one feature i really would have liked.. but popping the back open, I see the two leads for NFC, but the two leads near the right side of the battery for inductive charging on the international version is not on the Sprint version.. sad panda face
-- UPDATE -- Successful mod
I had to order a Sprint specific backplate from ebay
So I got the Nexus Wireless Qi Charging Orb.. and I drilled two small holes in the spare Sprint backplate I had.. I then proceeded to use some copper foil, folded it up a few times, and placed them in the hole with the sticky part on the housing. I then made sure the bottom of the folded copper was down enough to make contact with the contacts on the motherboard. Closed it up and then placed the receiver in the holes with the copper foil. Placed on the Qi charger and boom.. Wireless charging..
I did it this way so I can replace the middle housing and it won't look like I modded the phone if I need to take it in for repair.. Also, I can charge it with the Seidio Surface case on.

similar to wireless charging, but you lay the phone on a Charing Mat, and without the cords, the phone starts to charge .
Though OP, you're saying that it can't be easily fixed, with a Replacement of the cover? is that it isn't literaly on the phone itself?

I have the T-mobile and am about to modify mine for wireless charging just like my Verizon S3 is... It has already been confirmed working so I know that the T-mobile version has the same pins as the International does (which is GREAT) but I think it may require some stronger magnets this time around.

I think this can still be done I have to ask some folks I think you can run a connecting line to the battery connections through using copper tape, if this is so we just need someone with electronic know how but google copper tape you will see its thin conductive tape that can lead anywhere Im wondering if this mod can be done that way..

They are there they moved them up see the connection pos and neg are there just in different places top right next to speaker or is that nfc only someone let me know I don't have the device yet if so maybe you can run two leads from the battery connection pins on the phone but that's just a theory I don't know if the connection will charge your the battery once I get my phone I will attempt to mod with battery connection pin hijack to copper tape to induction coil.

I dont know but sprint really *ucked this model up if they would have left it alone like tmobile we would have been fine Im looking for a solution to the wireless charging but i dont know if its going to be possible all because sprint wants to be different and difficult. Ive been with sprint for 15 years but my patience is wearing thin.
Im still going to attempt a wireless fix though
whats this need yall help
Can someone help me, I dont have the phone yet so im trying everything in theory, to get wireless charging going. so I have questions!
What is this box
Whats the box for it doesnt look like nfc or a speaker or a microphone so Im hoping its tied to some sort of wireless charging, maybe a cover with the charging pins underneath (wishful thinking)
Personally I think wireless charging is overrated. There's a cable plugged in somewhere to get the pad going. And you can't use the phone while it's charging. Well, inconveniently you can. And it charges quicker via a cable.
I tried the Palm inductive charging mod like I have on my Galaxy Nexus and like people use on the SGSIII, and it does not register as charging. I didn't use the two pins underneath the cover, I tapped into the actual battery spring terminals. I went directly from the coil to the spring terminals with solid wire as a proof of concept and it did not register as charging. I had 5.6VDC coming out of the coil and apparently the current isn't high enough for our gigantic battery Looks like I'm going back to regular "plug it in" charging. Sucks...
I also did this mod on my note 2 but like you it doesn't register as charging. I did this mod on my s3 and it worked fine. Is it something with T-Mobile's note?

I think it just doesnt register the roughly 350mah as charging. Now that I have Perseus kernel he said he bumped up the usb charging to 900mah so it may work but I havent tried. Im guessing in stock form the Note2 just laughs at the paltry 350mah.
I keep using that number because thats roughly what my Nexus would charge at without kernel mods...

Yeah, I saw that. Before I hooked anything up I measured 0vdc on those terminals with the phone plugged in and charging. I tries those terminals first, then the battery terminals as everyone warns against. No charging in any circumstance on my device. Maybe my inductive pins and or associated circuitry was jacked up out of the box but I find that hard to believe. Im still waiting to see any Tmo Note users get it running. So far, only the N7100 has had success.

I just tried connecting 5V from a spliced USB cable to the inductive charging pins and the phone does not indicate charging on the T-Mobile Galaxy Note II.
Its a shame, because I have all the necessary hardware after doing this mod to my Galaxy Nexus.
Is it possible that this doesn't work simply because of the ROM. Sort of like how we can't do multiscreen?

No, I dont think so. There is something missing on our devices, hardware wise. This mod is still possible, you just have to take the phone apart to solder into the usb connector. I dont have the time or desire to do that...yet lol.

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 ?)

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.

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.

I just got an S3, and was excited about the ability to use wireless charging. While looking for QI gear on eBay, I ironically stumbled across an item that will add that very same feature on my old SII, without any permanent hardware mod needed.
The item in question is this: http://www.ebay.com/itm/200963522572?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
It's basically a QI charging inlay thing that has a very tiny microUSB connector, allowing you to connect it to essentially anything that charges via microUSB. I bought one just to try it out, and sure enough, it works like a charm with my old S II. I have a cheap (but great) TPU case on my S II, and the QI inlay fit absolutely perfectly between the case and the phone's actual back cover.
I used the SII for more than a year and a half, and I frankly hope that this was just invented a few weeks ago, as I hate to think that wireless charging for my S II was $16 away all that time >.<
Hey, *thanks* so much for this, it is just about exactly what i was looking for (and not able to track down on the net). Much appreciated and can't wait to try it out on my SGS2!

Does anybody got the incoming mAh stats about wireless charging?
Anyway, I think cable is better because you can move and use your phone.
