I bought a sticker to enable wireless charging for the G4, however I noticed that the sticker covers up the existing 2 contacts on the NFC that came as part of the plastic back. I'm not against installing the sticker to add QI charging, but I'm concerned that it blocks the contacts to the NCF which is already present. I assume others have used the same stickers to add charging and what to know what they had to say on the matter.
Thanks,
ERIC

I just purchased the same QI charging sticker and it has NFC built into it. You have to remove the current NFC sticcker in the case backing and replace it with the QI wireless charging and NFC sticker. The QI charging sticker should have the contacts where the NFC connectors are and also have the contacts for wireless charging, this is why the stock sticker needs to be removed.
Enjoy your wireless charging

The back sticker consists of 2 parts the NFC and also a black lump under it, which I assume needs to also be removed, no instructions make figuring this out fun! Found a picture on Amazon, as to the order of the stickers: QI first then NFC, seemed backwards, but that is what they showed., so that is what I'm doing
As for the sticker it is on and seems to be correct, but the charger does nothing, tried removing it replacing it I'm 99% sure it is correctly placed, but there is no way to check 100%; added some paper behind the contacts to move them forward, still no charging.
Assumed the sticker was bad, I bought 2 tried the second one same thing, tried both bases and both stickers (destroyed the one removing it), still nothing. So either the phone is bad unable to charge via QI, the stickers are reversed, unlikely given it matches pictures or it does not make contact, there is no way to be sure but I'm 99% positive they align. I do not really need QI, just thought it was nice, but currently I'm about to give up on it since the sticker simply do not seem to work and buying a case with it makes no sense.
Using a meter resistance is 0.06 Ohms, when off the QI, on the QI there is a pulse occurring so I assume that means the sticker is good, as a result I do not know what is the issue I do not see any way to monitor how much amperage is produced, perhaps it is too little to register with the phone as a charger?
My thoughts to date, QI via add-on sticker is a waste!, a very cheap waste but a waste ensuring proper contact is basically down to luck, and I'm not having any a 5 minute job has taken an hour of my life so far with no result to show for it.

I bought 2 stickers from Aliexpress, rebuild 2 Phones with the sticker, both of them are workin and charging flawless
we have the Black leather back, the embedded sticker in the cover must be removed to succuess.

Hey everyone,
I am really keen on having Qi charging and already have the pad and everything. I am looking to make the move to an extended battery (not the official one, which I hear works with the pads, but rather an ebay one, 4300mah, 4500mah etc with extended battery doors).
I know this will cause the contacts to be elevated above the spots requiring contact with the pad.
How are people overcoming this? I'd rather not solder to visible contacts inside the phone, and was curious how others have accomplished this and kept a consistent connection without permanently affixing it with solder?
Thanks!

Would like to see some pictures of this was thinking about doing it myself but wasn't sure if it would work, also would like to know which sort of copper tape they use..
Look for palm pre mod . It was the wireless charging mod before qi chargers were made for the s3.

the copper tape or copper wire trick will do.
there is a thread here where someone took a qi receiver pad and modified it to fit several extended batteries.. search this specific forum. it's there.

I am also interested in charging the extended battery using the Qi Wireless receiver for my S3.
I purchased the recommended copper tape but had no success.
Are there steps somewhere in the forums that could show you the steps?
I do not want to solder anything to the contacts.
Thanks for your help
search this specific forum. there's a link or a thread here with a step by step.
Hi this post is a bit old, but I think very relevant today. Most tags will not work with an extended battery because of where the chip is located. I'm finding that it needs to be lower and the only ones that do that are the ones with a longer contact neck. I just purchased a 6400 ma battery and back cover for my s4... and discovered my qi I receiver tag will not work... unless I fool around with it a lot like putting a bunch of tape underneath that neck part to raise it on the short version. But with all that little bit of extra tape makes the back cover insufficiently loose because it can't snap-in because it's too thick of a battery. But I played around with a little bit as I told you above and got it to work but I couldn't keep the back cover on. So my in-enept modification failed... I read a review on Amazon or a gentleman got it to work but I notice his cute a receiver tag had the longer neck. I know the company tylt makes one, & I am calling him in the morning just to verify that is the one actally still selling.
Extended Battery + Qi Pad, Back Plate Doesn't Fit
I'm having a similar problem with my Galaxy S3 extended battery + Qi charging pad. I was able to modify the Qi charging pad to fit above the extended battery pretty easily, even though the end result is a bit kludgy. Basically I just soldered two thin wires to the contact points on the charging pad then used a piece of foam to space the wires appropriately. I wrapped this in electrical tape and tinned the ends so they'd make a solid connection to the phone contact points.
>I can't post links yet but you can see a picture of this on imgur: i.imgur.com/KJOU4I5.jpg
This worked great, except that the extended back casing that came with the battery doesn't fit properly when the Qi charging pad is inserted. The back plate that came with the battery is made of hard plastic so it won't bend leaving me with an extended battery + Qi charging but no back case. All the back plates I've seen on eBay look identical to the one I was sent. I'm going to try heating and molding the back, or perhaps sanding it down (though it's already pretty thin) but at this point I'm not super confident.
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.
Hello,
I'm trying to set my g3 up with wireless charging (too many wires around my desk!) but im having problems.
I have the quick circle case, which I thought had wireless charging built in. I then bought the following product: http://www.amazon.co.uk/gp/product/B00M9TBTDM?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s01 hoping they were compatible.
I am thinking either the quickcircle case is only compatible with the official lg wireless charger? I never actually use the quick circle case anyway, just tried it for testing purposes. Would something like this from ebay enable me to use my normal back cover, to work with the type of charger ive listed above? http://www.ebay.co.uk/itm/QI-Wirele...ories_MobilePhoneChargers&hash=item2ed969a5c9
I have the F400L Korean model.
Any advice would be much appreciated.
Thanks
Adam
Have you got the snap-on or the replacement backcover variant of QuickCircle? If former, then you can't use it for Wireless charging IIRC, if the latter, check how many pins there are on the inside of the cover, if it has only 2 of them, then it has only NFC compatibility and no wireless charging available, if it has 4 of them, try to carefully align the device so the center of the device is aligned with the logo on your charger.

Hi, I have one that replaces the back cover, it has the 4 pins, I tried moving it over all parts of the charger, there were times when the phone would begin to charge, but this only lasted for a split second. But as I said above, im not keen on the quick circle case anyway, would much prefer to get it working with the regular back cover
will one of those stickers from ebay work to attach to my back cover? the listings suggest they dont work for my model; "QI Wireless Charging + NFC Antenna Sticker for LG G3 D855 VS985 D851 LS990"
Try swapping your USB cable and make sure your power supply is rated to put out at least 1.8 Amps.
I know that the G4 does not include wireless charging without the quick circle case which is why I'm confused about what the sticker is inside of my back cover. It looks like wireless charging... But I don't have anything to test it with. This is the Verizon version. See the attached picture

ahh so thats why the replacement stickers on alliexpress for 9 bux come with nfc and qi..tyvm for that snippet i was wondering what the hell the sticker was as well
Hi!
Have anyone tried it out or is it a big bs?
I call bull****. It looks like the normal NFC sticker located inside your phone on the rear panel. If this were true you should already be able to charge your phone with QI chargers. I don't see any extra connectors, and I don't think it would be possible to charge your phone through the NFC pins.
AFAIK Qi charging works by leveraging a magnetic coil (please correct me if I'm wrong) and I don't see a coil in this "add-on" so I also call BS

You are 100% correct.
Wireless charging needs a coil as it's charging through induction after all. What's being advertised is purely an NFC plate (if it were both it would've required a second set of connectors too).
