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.

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
Ok so I was told by a Sony store employee that the Z4 might have wireless charging and most likely it is Qi based. I have had a lot of experience with wireless charging with the N6 for which I bought a Tylt Vu since I was told it was the fastest but alas it's much much slower than the stock charger and also slower to a cheap Nokia stock charger belonging to some dumb phone.
I prefer the magnetic dock system it charges my Sony faster than the wireless system of the N6 it would truly be a step back if Sony only included Qi and deleted the magnetic system from the next flagship. Don't get me wrong the Tylt Vu is a very capable dock but when compared to the likes of Sony DK docks it's not half as grippy neither does it charge as fast.
What do you all think ?
I like the convenience of wireless charging that my nexus 5 had, It's something I miss on the z3. Not really a fan of the magnetic charging

Out of interest, how can anyone have a problem with magnetic charging? The usb socket is a weak point on many devices; often they're glued or soldered onto the boards with no regard for longevity - indeed, it wouldn't surprise me if they are deliberate weakpoints, exempt from warranty ("you must have broken it") etc. Magnetic connectors solve all that. Sure, add QI to magnetic (and usb, for data transfer if you can't use wifi for some reason) but I see no downsides to providing magnetic.

I agree that the USB port is the weak spot on a device, and will you bring up some good points I don't want to have both of them on my device I'd rather have one or the other but USB charging is more mainstream than the magnetic charging. I've only had my z3 for a few days and haven't gotten around to using the magnetic charging. Waitimg for the adpter in the mail.
Slow charging, for example overnight: Qi for comfort reasons, not cable attached and charging time doesn't matter
Very fast charging, for example "i got 5%, have to get out in 30minutes and got to make it through the day!": USB due to fastest charging times
Casual charging, for example "let's plug it in in the afternoon, my Z3 will make it through the night without any losses and through the next day": Magnetic charging
I don't want to wear out the USB port flap, so i bought the magnetic charging cable even before the Z3 arrived. I guess it will do in everyday usage, i'll have a look on the charging rates. If they're too slow for "power charging", i'll switch to USB.
However, a few months ago i only charged my phone over night. I would have loved to have Qi charging back then, so much better than to find out how to plug in the USB cable in complete darkness.

Some people claim the magnetic charging is faster than usb. I wouldn't know - i've only used usb to charge it once, and I was playing around with stamina mode at the time (for some reason stamina mode really slows down charging).
I wish this phone supported wireless charging! I charge with the Sony DK magnetic dock and it works well but can get a little finicky to get seated properly but I still prefer it to fiddling with those micro-USB connectors. I charge overnight 90% of the time and so even if wireless charging is slower that's fine with me. I'm ok having to plug in if I need a quicker charge when I forget to charge the night before, although with the Z3 that's not as big a deal because it's not too tough to stretch two days out of a charge with moderate use (on a bit of a limp towards the end of the second day).
This phone would be pretty close to perfect for me if it had wireless charging, a removable battery, and no ultra-slippery glass back (I really don't like the glass back!!).
I just slide the phone into the correct position no need to put in in a specific way. I have fixed the dock with double side tape all I need to find in the dark is the groove in the dock and slide the phone in place. As far as overnight charging is concerned I use the dock overnight without any problems. For the Nexus 6 the tylt vu dock its not a stable combo I mean it's really not sturdy any sort of vibration causes the Nexus 6 to detach so it's not the dock for overnight recharge.
I use qi chargers on samsung's phones and magnetic on Z ultra. Qi charger is very convenient and beside slow charging and heat disipation there is no minuses ( I have qi car charger from nokia and works well with all phones), magnetic charger is faster BUT you are still connected to a cable and the weak magnet is making the solution unusable in car. A COMBINATION OF THEM WILL BE THE PERFECT SOLUTION
P.S. Sony make some great accesories...why the h__l they did not made a magneting car dock I don't understand...
P.S.2 qi charger for moto 360 works like a charm....the best solution of all regarding smartwatch charging
Hi, I would like to ask you, what is your experience with that cheap S4 Qi receiver pads (for example from ebay...). Is it charging fast? How much is cover bulged? Is it dangerous for the battery?
Thank you very much for sharing your experience.
It does make the back cover bulge a bit but it's not bad.
The phone gets warm when charging wirelessly but it's not too bad at all.
Sometimes, the charging pad will detect the receiver but the phone doesn't charge. If I remove the phone from the charging pad for a few minutes and put it back, it will start to charge.
Charging wirelessly is not as fast as using a wired charger and I would say it takes about 30 to 50 percent longer.

Thank you for response. Is NFC working with that Qi pad?
I have never used nfc on my phone but I know you can get pads that do support nfc as an option.
Hi there
I have a qi receiver on the S4. My one has input: "self-adaptation" (whatever that means) and an output of 600mah. It charges at a decent speed. I use the LG G3 wireless charger and a few other wireless charging pads and they seem to charge at a decent speed. A full charge takes about 3 hours.
The cover does bulge a tiny bit, but it is barely noticeable trust me- definitely worth it.
The phone only gets a little warmer- again nothing to worry about for sure.
I am certain that it doesn't do any damage to the phone and battery. I have using wireless charging overnight everyday for the past few years on the S4 and nothing has gone wrong. I rarely use cable charging anymore
I recommend getting a qi receiver for the S4- it is worth it.
Has anyone found a Qi charging receiver so thin that it doesn't bulge at all?

Is it today something better what can more than 600 mA ?
Can you recommend something good ?
I can tell you the one from Aukey, although it uses a flat printed circuit coil, bulges a lot. Enough I didn't want to use it. It was advertised as being "ultra slim 0.2mm", but when I measured it with calipers, it's more like 0.9mm. The ferrite pad on it is most of the thickness.
No Bulge

The Fone Salesman S4 SlimPWRcard does not bulge at all.
I'm not finding clear info on if the V10 is ready to go or needs something added to enable a wireless charging on a wireless charging stand.
I've seen you you can add some kind of antenna to the back cover; when I remove the back cover on mine, there is already one there; but not sure if it is for wireless charging.
Can anyone fill me in?
That's for NFC, Qi wireless charging requires an new replacement back accessory. Just google Qi Wireless, and the NFC/Qi charging requires two Pairs of PIN connectors on the LEFT and RIGHT side of the back cover. By default its only on the RIGHT hand side, which is for NFC only
I bought a wireless charging "sticker" to retrofit my v10 for wireless charging. Installation was a little finicky but totally doable. You remove the existing nfc sticker inside the back cover and replace with one that does nfc and wireless charging. Then it will change with any qi charger.
I tried using it for awhile, but I kind of hate it. You have to line it up perfectly and even then it's incredibly slow. Misalign and it gets hot but slowly discharges the battery. I never use it.

I had the same experience. I tried it but it is slow and the phone gets hot. I never use it anymore.
I have a Qi replacement back, and it was awesome. But after a year it keeps turning off and my Tylt charger will blink red, wake the phone up, start charging. It'll get to 100% over night, but I don't like it.
I am currently using: LG Wireless Charging Backcase CPR-120 für V10 schwarz, CPR-120.AGEUBK (from amazon.de) together with Samsung EP-PA510BWEGWW Wireless Charging Plate Mini - White and this is working fine. I did try a cheap backcase from e-bay but that one started falling apart (first some cracks and then pieces around crack fell off) so not bothered to try any others.
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?
