[Q] Any solutions for QI wireless charging Zerolemon battery?

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.

I have 3 pads that fit the original note 4 and work with it, I'm open to any suggestions on how to extend the flexible flat cable -- I can't find a way to do in online anywhere!

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!

In case anyone's still wanting to hack a Qi coil on a Zerolemon battery, it works just fine. Here's a step-by-step with pictures. http://traff.as/zerolemonqi

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.

Q I charging problem

I picked up an lg QI dock and tryed to let the g3 charge off it. Would not work. So found out that the us versions of the g3 do not have the correct back to work on qi dock charging. bought a replacement cover and then tryed to use dock.
the phone would go into charge mode for a few seconds and then stop charging. tryed moving the phone in differant positions and still no charge. then one night the phone charged, but it is intermitant. Is there something Im doing wrong?
thanks

The original back cover should of worked right out the box, I think the wireless charger is defective you have, try another one.

Qi chargers vary in signal strength and have an effective "transmission range" that is dependent on how thick the case of the transmitter is and how thick your phone's case is, if you have one on it. If you have a case on the phone try taking it out before you charge to see if that helps. Otherwise you may need to look for a "stronger" charger (they should have "transmission distance" or "charging distance" listed and anything 5mm or less is useless in my experience).

The US versions do not support wireless charging out of the box, as the OP said. I am waiting on a replacement antenna to handle both NFC and Qi, myself. I really got spoiled to the wireless charging with my Nexii 4 and 7...

[Q] d852 to try and use Qi ?

So, I've got a Rogers LG G3 (d852) ... and I've bought a Qi case for it that says it's for the d850 (which the mid frame back has d850 written in various spots). The sticker's contact points line up, but when I put it on a Qi charging pad it doesn't work. Testing out the NFC and it doesn't work either.
Hopefully it's a bum case... But I also purchased a d850 back plate that has NFC and Qi receivers, so I'm hoping those will work.
Doing some research it says the d852 is PMA ... but if I replace the receiver on the back, should it not work with Qi?
Help? What are the differences between the d852 and the d850 (from what I can tell it was which bands the cell operated on and nothing about battery contact points etc...)

I don't think you can just change the charging coil to make Qi work on D852. It seems D852 is missing the Qi charging circuitry inside the phone. Your best bet is get an PMA charging sticker and put it in your back cover to enable PMA wireless charging like this:
http://www.ebay.com/itm/LG-G3-PMA-W...923?pt=LH_DefaultDomain_0&hash=item2ed9ec328b

I thought the 'receiver' that's the sticker on the case is the coil, and the leads in on the phone just provide the power.
The extra weird part is that the NFC doesn't work either.
I've ordered a Qi back plate to double check.

That is not true. The coil is just one part of the Qi charging system, it is not the receiver. There is a receiver IC in the phone that does two way communication with the Qi charger via the coil before any charging can happen. Think of the coil as a wifi antenna, and the receiver IC as the wifi card. Without the wifi card, it is pointless to put a wifi antenna there. Your wireless receiver IC is of PMA, and it does not work with a Qi coil.

Now it's funny because I went and called LG tech support yesterday (not saying they're the most savvy folks out there, but you never know).
According to them, the d850 and the d852 are exactly the same (some bands are different for carriers in the US), and even within the d850 line there's PMA or Qi charging backs but the internals are the same (or so they say).

[Q] Wireless Charging and LG G3

Hello guys, I've been doing some searching around and I can't seem to get wireless charging to work on my LG G3.
I recently purchased a NFC/Qi sticker and successfully replaced the old NFC-only sticker on my backplate. I have checked and made sure the NFC/Qi pins and the terminals on the pad make contact.
I have also purchased a CHOE Stadium Qi Charger, which was very highly praised around these parts.
My issue is - wireless charging is very unreliable. I place the LG G3 on the charging pad, and it does charge for approximately 5 seconds before turning off, and then charging for 5 seconds again, then turning off. It repeats this cycle indefinitely.
I have tried restoring back to a stock KitKat image and see if the Lollipop update was causing issues, but the same issue persists. I've used both stock Lollipop ROM and the BlissPop ROM to no avail.
Anyone here have any ideas as to how I can solve this?

Make sure that the power supply you are using is putting out enough amp. I have one of these cheap ones here that does exactly the same thing. Using a good psu it works fine. Plugging it into my PC sometimes work and other times it just goes hair wire.

I've used the charger that came with the LG G3 (1.8 amp) and a 2.4 amp charger. Still doesn't seem to help.

Check to make sure you have the pins lined up with the pads on the charging sticker.

Wireless Charging Issue Update 13B

Anyone else having issues with wireless charging since the 13B update? I do not if it is just coincidence or not but both my wife's and my G4 refuse to charge through wireless. This problem seemed to begin after both phone's were updated to 13B. The light on the charging pads does not even come on. In the case of my G4, I have actually wiped the phone after the 13B update and still encounter the issue.

You should check to make sure it's not that the sticker on the back has stopped making contact with the wireless charging pads... All of mine have consistently stopped working after awhile because of that, however, if I take the sticker off and press it to the contacts physically it still works.
Although after fighting it for weeks I've given up on wireless charging for this phone.

Hardware issue is a possibility but, I have two LG G4's here that both stopped working at the same time. I experience the issue on multiple charging pads also. This was right after both phone were updated to 13b.

I'm on 13b and my wireless charging works as well as it ever did, which isn't spectacular. I'd say 1/10 times I wake up and its not charged. I even bought the official flip cover case with qi as I originally blamed my sticker back application skills.... but both work equally crappily....

Wireless charging on my 13B is rock solid. FWIW this is the wireless charger I use: http://www.amazon.com/Wireless-Yoot...9605910&sr=8-3&keywords=lg+g4+yootech+charger
As long as I ensure that it is steady green on the charging light by properly aligning the phone to the pad, I have never had an issue with it not charging properly.

I am not sure why I am still having issues. I did a battery pull on both phone and they started charging. But now half the time neither phone charges or I will wake up with the phone only partially charged. I just find it really hard to believe that both phones are having issues with two different chargers at the same time and that it happened right after I updated to 13b.
This is the charger I am using: http://www.amazon.com/gp/product/B00JA7HNZO?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00

If I plug either phone in using the same cable that goes to the charging pad I have no issues.

Thats what I figured, but had to ask. Have you tried charging it with the phone off? Could be the new software requires a greater amperage than before so charging with the phone on could cause issues. I know your charger comes with its own USB cable but what about the actual wall wort? Are you using the standard LG wort? Im just drawing at straws, but hopefully something gets your issue fixed. Other than that I guess at this point, since you already tried different chargers you could see if replacing the Qi sticker in the phone has any effect.

The LG G4 doesn't support wireless charging unless the NFC sticker on the back cover is changed out for one that is NFC/Qi charging capable. Look at the NFC sticker on the inside of the back cover. If it only has one section of the sticker with two metal pads, then it's only NFC capable. There should be two sections / arms with two metal pads on the sticker. one for NFC and the other for wireless charging. You can buy a new pad online for $10. My Verizon LG G4 didn't come with the wireless sticker , only the NFC one. See the picture for details of the NFC/Wireless charging sticker. :good:

I bought a new sticker that had both NFC and QI, and it was charging without a problem for a couple months. Now mine does not work at all and my wife's G4 only works sometimes.
