thank you.
I know there are replacement covers which support wireless charging and NFC operation. There are also some Wireless Charger modules which allow NFC operation but they make the back side a bit thicker. Current versions allow NFC while previous versions were fixed with a thin metal foil which shielded the NFC signal
But replacement batteries which allow NFC operation ... I can't imagine that because the bigger battery would make the phine thicker (means reducing the NFC range) or cover a large area of the back, NFC area included, and the NFC signals will be shielded by the battery.

Umm... the NFC antenna is built into the battery, not the phone. There is no "NFC area" other than on the battery itself. The OP is asking for the largest capacity stock size battery with NFC capability.
just buy the oem battery kit !!
works like a charm!! charges batteries in 1hr 40min precisely .... with the oem charger !!
There's none except from original Samsung battery

Ugh, didn't know that until I looked on my battery after your post. The battery of my SGS1 has 3 contacts (+, - and a safety pin (battery temperature? )) while the SGS4 battery has 4 pins and a label "Near Field Communication".
With "NFC area" I meant the area where the NFC antenna is (inside the battery I know now). Any NFC tag has to be within the range of this antenna (a very low range, a few millimeters only) to communicate.
Anker 2600 battery kit, you get 2 so you can swap between the 3 while one charges and yes they come with NFC if you choose
I wonder if Samsung will come out with 3000 extended battery like they did for the S3

I've got one of those cheap Chinese inlay antennas (plugs into dedicated S4 pins, fits over standard battery under standard back cover, bulges the back cover ever so slightly).
I've been using it for a year or so, it works fine overall, but it seems phone doesn't last as long with this wireless receiver / antenna installed.
I've tested it, trying to keep same usage:
with antenna: 16 hours from battery full to empty
without antenna: 40 hours
That would imply that either antenna drains batter at ~100mA rate when not charging, or that when phone is charged (via wireless), battery is not charged as well as phone thinks it is.
Did anyone have any similar experiences?
Does the receiver support nfc? Not sure if disabling nfc would make a difference.
I have an s4 with a similar qi receiver without nfc support and battery drain has not changed for my phone.
I've always had the understanding that the NFC antenna was part of the OEM battery and the antenna is discernible when looking at the OEM battery. I've been using an aftermarket powerbear battery for a while now and it does not have the NFC antenna. Yesterday I had forgotten that the aftermarket battery was in there and went to buy a soda at the vending machine where there is a wireless payment option. The NFC payment worked just fine. So, now I am confused as to how it worked without the OEM battery and the NFC antenna. I do have the Samsung back cover with Qi charging so maybe this alternate back cover has the NFC antenna in it as well as the Qi charging loop. The back cover has six electrical connectors that mate to the phone when installed.
Hey everyone,
I'm using the TQTHL extended battery which gives me 24 hours of juice for my Note Edge N915-T
Unfortunately, it doesn't come with an NFC receiver (Present on original battery), so I can't use Tap & Pay.
I was able to get an NFC antenna for the back door, but the chip is still needed for NFC to operate.
Does anyone know if we can buy the NFC receiver separately somewhere?
Search in ebay
Hi friend, there is no NFC-chip on battery pack, it's only NFC antena.
Hi,
I want to retrofit wireless charging capability with one of those thin receivers you can put between your phone and the case and then plug into the usb port. The only thing that worries me is a coil or antenna or something which is sitting on top of the battery. I can be seen in this disassembly video: https://youtu.be/kNzDbb-lJzs?t=42 This would probably be covered by the added receiver. What is this? Would covering this up be a problem?

NFC.
It doesn't seem like a good idea to me.
Mhm, ok. If I don't want to use NFC anyway would this be a problem? I mean, the phone should be able to handle beeing placed on a qi charging station (if someone is ignorant that it does not have this function) without induction of any harmful currents into that antenna, right? So I would just loose the NFC functionality if I shield it with the receiver patch.

My reaction was not about NFC, it is even possible that it will continue to work, maybe it will be less sensitive. I just expressed my opinion that I personally dislike your intention, because I don't think wireless charging is a killer feature for the ZF6 that we have to regret not having. Moreover, our battery size and space in which it is located and cooled, and so on is not at all adapted for continuous wireless charging and higher charging temperature.
After all, we don't charge so often with our big battery, and when you charging by cable, you charge more environmentally and faster than with the best wireless charger. That is to be remembered, and that is what I meant and what was my point.
For me NFC and big battery are killer features, but wireless charging isn't.

OK, I am getting your point. I just bought this phone, and was not used to having a battery that can go two days easily. I have qi chargers scattered around everywhere (car, office, living room ...) to top up my battery whenever I lay my phone down somewhere. That is starting to seem a bit pointless. I just discovered the function to slowly (and therefore least damaging to the battery) charge and reach 100% at a specified time. Perfect for overnight charging.
Let's give it a few more days to see if I still feel the urge to retrofit wireless charging.
But from the purely technical standpoint, I had another thought. The qi charger only switches on the charging field when it detects a compatible device set down on it. So it would not do that if an untouched Zenfone 6 would be placed on the charger, and there would not be any danger of inducing currents into the NFC antenna and damaging something. Now, if I retrofit a charging pad the charger actually does produce a field when the phone is on it, thats the whole point. No idea how much current would actually be inducted in the NFC antenna, but I am very certain it is not zero. Does someone have the technical background to at least make a guess?
After doing a battery replacement, my NFC has stopped working. Since the battery was swollen to the point of bulging the back, I assume something got damaged during the replacement.
I have found a replacement part for the NFC antenna, but can't find where it would go. The only information I've been able to find is that it's under the fingerprint sensor. That wasn't touched during the repair.
Does anyone have more detailed knowledge of the NFC antenna?
The nfc antenna is actually placed above the battery. So it could be that someone who replaced the battery didn't plug it in
How do you not touch the fingerprint sensor while replacing the battery? The NFC wireless part gets screwed on over the battery after swapping it.
It's not on the fingerprint sensor. It's coupled with the battery and maybe the wireless charging coil if it has one

Thanks for the info. Where would it be coupled on the battery? I see the contacts for the wireless charging coil (which works just fine) but nothing specific for an NFC antenna. So I'm wondering if it was disposed of with the failed battery.
