While reading around the net, i picked up a few pointers.. the insulation material can also block the nfc signal.

The NFC points are mainly located at the top of the battery where it says NFC.

I trimmed around the edges of the QI receiver on the top and now NFC works perfectly fine. I dont have to struggle and make multiple passes.. just one tap and NFC picks up the tasker profiles.

Here is a picture I have taken to demonstrate on how i fixed this issue.. for anyone in the future who might encounter this.
[Galaxy Note 3 Accessories] YoungSkeezy:
The official Samsung back for wireless charging makes all my cases useless because it doesn't fit anymore.

Anyone found a solution for this?

Oh and what's the best wireless charger? Mine is the small choetech one. Have to lay it very specifically or it won't charge.
[Galaxy Note 3 Accessories] MANswers:
That is one of the reason, this and another thread has become a beacon for wireless charging for Note 3. Most of the discussion you will find on this thread is for the seperate QI inserts that we all are using. The reason most of us here did not buy the official samsung back cover. If you had followed this thread from the start you would have known.. that people already knew that the OEM back cover does not fit most of the covers.

Just get the qi insert mate, and follow the procedure.

here's the link

http://www.ebay.com/itm/131015696933

Follow the video.. and you can use ur original back cover with any case. I am using with Neo Hybrid.. no bulge.
[Galaxy Note 3 Accessories] DutchDogg54:
Unfortunately, there's no solution for this - the only thing we can do is wait for case manufacturers to see this as a need. This is the reason I haven't gotten the official back myself. I guess the best thing we could do would be to email case companies to explain the situation and let them know the demand is there.

The wireless charging on the Note 3 is much faster than the Note 2... Do you guys know by any chance if there is already a modded Kernel for even faster wireless charging?
[Galaxy Note 3 Accessories] AssassinsLament:
I just received a Bear Motion Bumper and it fits perfect, the back cover is exposed so you don't lose the leather texture, plus you don't have to worry about a Qi insert affecting the NFC and a case that affects Wireless charging.

My nfc is working fine so I'm content.
[Galaxy Note 3 Accessories] mopar:
Here is an easy fix for nfc I had an spare nfc antenna from my note2 that I purchased off ebay for $2 I installed it and used a little tape to hold it in place. ..
[Galaxy Note 3 Accessories] RojasTKD:
How the added thickness?

Fits cases fine
[Galaxy Note 3 Accessories] RojasTKD:
Thanks, hopefully I won't have NFC issues. Good too know there are work around if I do.

Does note 2 NFC antenna fit the note 3? Or a mod is needed"?
[Galaxy Note 3 Accessories] Kawaisa:
nvm...
[Galaxy Note 3 Accessories] mopar:
Drops right on no mods I put a small piece clear tape to hold it in place and a piece of foam double stick tape to put pressure on the contacts my be over kill but it works great.
[Galaxy Note 3 Accessories] MANswers:
Thanks for the pictures mopar. I have ordered the nfc antenna for 4 dollars from a US seller from NJ, i might get it by monday.

Here is my observation with NFC and the QI receiver. Definately the NFC does not work as perfect as it used to be when there was no QI Charger.

You gotta do few extra passes, and also need to make sure that you are touching the tag at a certain spot behind the phone. Previously even before i tag the phone few inches away from the nfc tag it would pick up the signal and execute the command, but now its not the same.. you gotta do a few passes.

If you are trying to tag two nfc based phones to each other, it works fine, but if you have a regular NFC tag.. you need to be precise about the spot and there is delay in finding the right angle and point to touch. Its not perfect.

I hope this antenna might fix the issue. Mopar, after adding the nfc antenna is your reception and tag functionality as good as it used to be before inserting the qi receiver?
[Galaxy Note 3 Accessories] krelvinaz:
Only problem with that is that the Secure element is IN the battery NFC not in the phone. So if you use a secondary NFC antenna, the Secure Element will be missing (I think). I don't think you can access the Secure Element in the battery when there is another NFC antenna in use.

If we end up with KitKat, then that may be a mute issue since apparently it implements a software secure element process.

This info was wrong.
[Galaxy Note 3 Accessories] kcfong2:
Are you SURE Qi works on N900T (TMO)?

Hi, there are multiple threads on N3 wireless charging, so I'll keep the post to this main thread... I have the TMO (N900T), rooted stock (delavega). I ordered the eBay receiver and charging pad kit, I read through this thread and the associated TMO one (which confirms charging should work with N900T), and watched the associated video(s) ad nauseum. My problem is, my Note 3 is NOT charging via Qi, and I can confirm the charger pad and receiver are working. What I did notice however, is that when I place my + probe of my multitester to the "S4+" pin on the receiver, and the - probe to the "S4-", I'm reading -5VDC, and (obviously), when I reverse polarity, I'm reading +5VDC. I sent an email to the eBay seller, but haven't got a response yet. Can anyone confirm, (1), does wireless *really* work with N900T, and (2), if it does, is the polarity on my receiver correct or reversed? If all seems to be right, does anyone have any idea why the receiver and pad are registering (I'm getting 5VDC), but the phone still won't charge wirelessly? Did the eBayer send me the wrong receiver? The fact that the pins are labeled "S4" has me a bit concerned. Attached are two photos with multimeter readings. Thanks in advance.
[Galaxy Note 3 Accessories] YungMage:
The S4 pins are switched from Note 3 so you have to reverse the pins if he sent you an S4 one.
[Galaxy Note 3 Accessories] kcfong2:
Thanks. I suspected something was wrong when I noticed the pins with S4 labeling. I'll have the company (from China nonetheless) send me the proper receiver. At least (or I hope at least), this "S4" receiver did not fry anything on the phone... it seems to be working fine, and charges normally via the USB... and there was no smoke ;)
[Galaxy Note 3 Accessories] YungMage:
Yea it shouldn't cause damage. Yea have them send you another one or return it and buy from someone else. Or you can reverse the pins yourself. The power is yours. Lol
[Galaxy Note 3 Accessories] gnik luap:
The S4+ and S4- labels do NOT mean this receiver/insert is for the S4.

My receiver from Docooler has the same markings and works perfectly.

On mine the top contact is labeled S4-.

Make sure you are using the top and middle contact left not the battery.

Try looking at the contacts on the receiver to figure out if they're too big to fit down against the contacts in the phone. One commenter said he had to trim a contact on the insert to make it reach the phone contact. Those are slightly recessed.

Another buyer said the contacts on the insert were too close together and they had to spread them slightly apart.

It's also possible the problem is in the phone, you can check by borrowing an insert from someone else or getting a charging back from a local Verizon store. Yeah, I know those aren't likely to work out unless you know a lot of Note 3 owners locally.

Good luck, and post again when you get it working.
[Galaxy Note 3 Accessories] RojasTKD:
I don't believe the Galaxy S4 receiver would fit a Note 3. The pins are oriented differently. I don't have an S4, but from the photos I've seen the the pins on the S4 are above the battery and it would be obvious the receiver is not for the Note 3.

At first I couldn't get the pad to work with my Note 2 and I thought it wax broken. I kept passing with it and it did work. Make sure it's making good contact.

Have you tried a different charger?

I am looking for a kernel that increases the wireless charging speed... Does any available kernel does that? None mention it...
[Galaxy Note 3 Accessories] aalupatti:
I had the same issue. My tmob note 3 not charging as well..
[Galaxy Note 3 Accessories] parusia:
As far as I remember at least on T Mobile Galaxy Note 3 the secure element is on the SIM card. Please correct me if I wrong.
[Galaxy Note 3 Accessories] krelvinaz:
I am delirious.... it is in the SIM card. You are correct.
[Galaxy Note 3 Accessories] ACalcutt:
one thing I don't like about the about the charging pad insert I got (compared to the official charging back) is that the coil is not in the center of the phone. Now when I place the phone in the car dock it needs to be almost an inch further to the left to start wireless charging. With the official back the phone charged perfectly centered in the dock.

I'm sure this is just a nitpick, but I like the phone centered better. I bought one of those bumpers that work with the wireless charging back...so maybe I will use the official back after all...we'll see.
[Galaxy Note 3 Accessories] MANswers:
Hey guys,

I found one QI power bank on ebay for 20000mAh, intrestingly the seller adds a line within the description of the item as below.

Attention!
Any kind of energy transfer from one device to another, is not 100% perfect in reality.
For avoiding of the misunderstanding, we explain the capacity here again:
20000mAh is the inside batteries capacity, under 3.7Volt of the voltage.
Output voltage is 5Volt of USB port, we have to convert the voltage from 3.7V to USB 5V
the capacity under 5Volt will be 3.7/5 of the one under 3.7volt, and the conversion efficiency is about 80%
plus some energy waste, the Pure Output Capacity from USB port is around 10000mAh.
If you are using QI wireless charging, QI efficiency is 70%.
The Pure Output Capacity from QI wireless is around 7000mAh.

http://www.ebay.com/itm/QI-wireless...0mAh-for-phone-tablet-universal-/161134452478

Does it mean the previously seen 10000mAh's battery pack posted on this thread such as this is going to be 3500mAh based on this logic?
[Galaxy Note 3 Accessories] RojasTKD:
I'm no expert, at 80% efficiency you should be able to get about 16000mAh useable power. At 70% you should get about 14000. The wireless charging will be less efficient, losing an additional 10 to 20 percent or so. I doubt that device has the capacity or efficiency they are stating.

Most chargers are in the 72 to 78 percent efficiency range. Top quality chargers can do a better into the upper 80% range.

You shouldn't look at capacity only. You have to look at efficiency also. That's why I like the Anker chargers the seem to be a little more efficient than most. The guy that reviewed there wireless mobile battery charger started he got more than 5000 usable mAh on a 6000mAh battery. He didn't have a QI device to test the wireless efficiency but it should be in the 3500 to 4000p mAn range, give or take.

http://www.amazon.com/High-Capacity...TF8&colid=1QJ6QEE6XM0GL&coliid=I392EEYSSCSO27

As for the 10000mAh QI battery I would expect better numbers than 3500mAh, if it's really 10000mAh and had at least a 70% efficiency. I actually bought one from DX .com mainly because it was less than $38, and at that price I was willing to take the risk. I still would like this Anker, but not yet willing to pay $70 for one. It ifs on my wish list though.
[Galaxy Note 3 Accessories] Malevolence:
I'm about to buy one of these gold or black receivers on amazon but it says output: 500ma Wouldn't it be wiser to buy one that says 1000ma?
[Galaxy Note 3 Accessories] TEKHD:
Of course... The blue pad... (1000mA) Check post #335
[Galaxy Note 3 Accessories] Malevolence:
does it bulge out? I don't want to "break" my back cover
[Galaxy Note 3 Accessories] RojasTKD:
Will it bulge out? Yes, a tiny bit. All the receiver pad will.

It will not break your back cover.

I'm sure this has been discussed.
[Galaxy Note 3 Accessories] Kawaisa:
I'm also looking at the blue docooler one on Amazon and reading a few pages back, I'm guessing the issues mentioned are due to user error and not because of reversed polarity or S4 receivers being sent?
[Galaxy Note 3 Accessories] aalupatti:
I have blue reciever. When trying to remove the blue cover the one of the connections from coil to the board came off.

Can someone post a close up picture of the circuit board with the conection so that i can try to solder back it.

Thanks
[Galaxy Note 3 Accessories] RojasTKD:
I have the Blue receiver (got mine from eBay) and it works fine for me.

Did a little test last night with the Note 3 and Note 2.

- The Note 3 charges at about 20% per hour

- The Note 2 charged at about 13% per hour
[Galaxy Note 3 Accessories] gordonzhao:
I will say this, be very careful with these inserts when removing them if they are taped down. I guess I was less than careful and it snapped the soldering on the 2 pins going into the board. Had to solder it back on.

---------- Post added at 10:42 PM ---------- Previous post was at 10:41 PM ----------

When I had my note 2 I read of kernels that helped 'unrestrict' the charge limit. But then again if I'm charging it over night I don't really care, as long as it's 100% when I wake up.
[Galaxy Note 3 Accessories] aalupatti:
Can you post a picture of the soldered points. I cant figure out where one of the points is getting attached to.
[Galaxy Note 3 Accessories] Kawaisa:
I've put off getting into wireless charging, but I can resist no more. Bought the blue receiver off ebay and now I have to decide on a charger.

I'm leaning towards the Nokia DT-900 since it's cheap and reliable, but it has a proprietary plug and it only outputs 750ma
[Galaxy Note 3 Accessories] krelvinaz:
I'm looking for an extra pad... I am looking at http://www.amazon.com/Lerway-Wireless-Power-Charger-Lumia920/dp/B00E9MUNWU

I already have a number of 1.8-2.1A USB chargers lying around that I can use and it uses a std Micro USB connector on the pad itself which is a plus.

The one I have is the one I got via Ebay, white and has a short proprietary cable. Black would be nicer looking.
[Galaxy Note 3 Accessories] MANswers:
I have posted an image a page or two back. Also a few posts earlier i had mentioned to be very careful while removing the blue cover. However you can still solder then back.

Hey guys another thing i noticed.. out of curiosity to get the receiver from china, i ordered from three different sellers, and most of them came in a week.. the receiver pads connectors are the same, the blue cover is the same, but not all the identical looking receivers are the same.

Two of the three receivers are thinner than the other one and is not flexible. O.ne of the receiver has a thicker insulation board on which the coil is wrapped. The other two are very thin.. and flexible. I replaced this thinner receiver with the previously received thicker one and now there is no bulge at all. Infact the NFC also works perfect... just like stock without the qi insert.

Even though the inserts look the same but there are two different types of inserts available.

The thinner one is a champ.
[Galaxy Note 3 Accessories] MANswers:
There you go. Let me know if you need more
[Galaxy Note 3 Accessories] mopar:
Can you post a link to the thinner one you got?
[Galaxy Note 3 Accessories] RojasTKD:
The Nokia DT-900 is a very good charger and great value at the $24.50 AT&T is selling them for. I would not worry much about the 750mA output, that more than most devices will even accept. It not using a microUSB matter little to me, they spend their time in a fixed place. Also Nokia's charger running on 12v make it a perfect candidate for an in car install, if anyone wanted to get into that.

The Nokia DT-900 has three coils and is thus very forgiving along it vertical axes when placing a device on it. Oddly enough the Nokia DT-910 only has one coil, probably because is made with their phones in mind so they know the perfect spot for the coil.

http://nokiagadgets.com/2012/11/25/nokia-wireless-charging-plate-teardown/

Only other charger I know that has three coils is the Tylt Vu, and it's coils internals look almost identical to the the internals of the Nokia:

http://www.kickstarter.com/projects/800343142/vu-wireless-charger-free-positioning-wireless-char

Just about all other charger have a single coil:

I have several DT-900 and a couple of Tylt Vu's. The Nokia is great for the price you can get it for. The Tylt is excellent if you can get it from T-mobile's site with the 30% off code.
[Galaxy Note 3 Accessories] rawdikrik:
You go through all the trouble of writing up that great description, and then you dont bother to actually say which are the good ones to get and which arent.

[Galaxy Note 3 Accessories] Kawaisa:
Thanks, how long does it take to charge with the Nokia per hour or from 0%? I'm guessing it's the same with TYLT since the input of the N3 stays the same
[Galaxy Note 3 Accessories] RojasTKD:
Seems to be roughly the same. Honestly I never get anywhere near zero.
[Galaxy Note 3 Accessories] MANswers:
lol, i understand.. my bad. I am gonna post the pictures tomorrow am.. But surely the new set of thinner receivers are far better in terms of NFC and bulge.. (infact no bulge.. not even 1%)

---------- Post added at 04:44 AM ---------- Previous post was at 04:41 AM ----------

Get a TYLT Vu mate.. i already have one, including 3 other ebay qi charging pads.. TYLT owns them by miles.. i never had to look, analyze, plan and execute my steps and actions on placing the phone on a wireless charger like i have to do with the other charging pads.

On the TYLT, i casually shove the phone on the charger and it picks up the spot cos of the three coils. At some point eventually i will add TYLT at multiple locations just like i have the chi-bay junk.
[Galaxy Note 3 Accessories] gordonzhao:
Anyone know a good coupon deal for the T Mobile tylt? I'm considering getting one as the viewing angle is a plus for me since I use it at the nightstand.
[Galaxy Note 3 Accessories] Mofo84:
You can use FALLFUN30
[Galaxy Note 3 Accessories] krelvinaz:
FALLFUN30 IS AN EXPIRED COUPON according to the webiste
[Galaxy Note 3 Accessories] RojasTKD:
Seem you may be out of luck then. I guess I got in just in time I used it last week.

Might try a Google search for T-mobile coupon codes, that's the only thing I can think of.
[Galaxy Note 3 Accessories] Kawaisa:
Use code: ACCOFFER18

My finger is itching
[Galaxy Note 3 Accessories] RojasTKD:
Did you read my post? I have two Tylt Vu's. The Nokia also has three coils. In fact the coils look almost identical (See pics below).

Yes, the Tylt looks "cooler" and has angled base, and if that important to you the Tylt is a great option, but not everyone want to spend extra for that. I have a Vu on my work desk and one for on home desk along with several Nokia's chargers at both home and work. If you buy more then one from AT&T you get a discount making the Nokia best bargain in my opinion.

Remember the Nokia DT-900 is $24.50 at AT&T right now and if you buy two you get a discount, three or more will give you a bigger discount so your paying under $20 per charger.
[Galaxy Note 3 Accessories] RojasTKD:
I tested it and can confirm it works. :thumbup:
[Galaxy Note 3 Accessories] Kawaisa:
I didn't realize they charged for shipping, which makes it about $60 after tax

You can get 3 Nokias for the same price
[Galaxy Note 3 Accessories] RojasTKD:
Yeah no shipping fee with AT&T. Three Nokia's vs one Tylt is pretty compelling. But are you going to want a Tylt and eventually get one or similar. Just remember the Tylt has a larger footprint and will require more real estate where ever you put it.

Personally I would get the three Nokia's to start. It works great if you have more than one charger in strategic areas to always keep you phone topped off.

I have toyed with the idea of building a stand for one of my Nokia's so it hold the phone at an angle also.
[Galaxy Note 3 Accessories] MANswers:
Thanks that is new information for me. I did not know that Nokia had three coils. I wished this was discussed in the threads earlier. I would have desisted in getting the chibay charging pads.
[Galaxy Note 3 Accessories] gordonzhao:
Wow still $49 before tax and shipping.
[Galaxy Note 3 Accessories] krelvinaz:
The Nokia is $24.50 at AT&T right now. Less if you buy more than one.

Free Shipping as well.
[Galaxy Note 3 Accessories] @rbiter:
Wow. $55.14 before tax for 3 Nokia dt900's. You get 25% off for buying 3 accessories or more. Hope this is still alive Wednesday when I get paid. Really wanted chargers with micro USB but can't pass that up.

sent from my sm-9005.
[Galaxy Note 3 Accessories] RojasTKD:
Yep, it really is a good deal. Better than all the other cheap chargers.

FYI, that the Nokia has issues with the Nexus 4. So if you have a Nexus 4 it might work for you. It has something to do with the Nexus 4 implementation of the QI standard not being completely in spec. I think later runs off the N4 may have fixed this.
[Galaxy Note 3 Accessories] Namuna:
Big THANKS to the person that came up with the idea of the Nokia DT-900 through AT&T...I went through my company store and got 3 of them for $51 shipped!!

Feel free to hit the thanks button :D

The Nokia DT-910 is also available and a stand, but it's about $51 and only had one coil. Being a single cool and a stand, you can't really adjust position vertically so some phones may not work. I do believe the Note 2 and 3 will work though. Buying multiples will also get you a discount with free shipping.

You said the cover recessed the camera module. Does it make the back of phone flat, so it will sit flush on a table top, or is there still a "bump" around the camera?
