Wireless Charging thread.

Note 3 supports Wireless charging as did the Note 2.

Wireless charging is a MUST for me as I have many devices and im getting sick of plugging in wires.

Looks like Samsung is introducing the extremely expensive "official" wireless charging setup,

But we will also have options such as QI in which you can buy just the reciever and stick it under any cover you like.

Lets see what options we have here and compare.

How did they mess up the Note 2 besides the decal on the home button?
I havent been around the Note 2 scene at all due to being stuck on my launch day vzw Gnex.
They removed the charging pins and covered it up with plastic (u'd have to drill holes then use copper wiring if u wanted it)

That is rather stupid of them, its an accessory they can sell but of course it's Verizon and they are always NOT looking out for the customer.

okay, so what all is this going to entail for me? I'm not really familiar with wireless charging on samsung devices, as far as I know it's 'pseudo-supported' but not out of the box, is that right? I'm coming from a nexus 4 and I have a few Qi chargers around the house that I'd really like to work with my Note 3...what do I have to do to accomplish that task?

On the Nexus 4/Droid Maxx its built in while on the Note 2/S4 that leave the pins so you can buy the Qi receiver (Samsung has their own back), there is the slim possibility that Samsung has it built in but unlikely.

Any word on this? I also posted the question on Verizons site but no answer as of yet.

I asked Verizon in chat and they gave me a pretty straight forward answer

"You: will Verizon block the Wireless charging capabilities of the Note 3 as they did with the note 2. (ability to add the wireless charging back to it)

Lonnie: No, they wont.

You: so the note 3 will have wireless charging with the added accessory?

Lonnie: Yes."

take it for what it is worth, but it sounds like good news to me.

They left it open and normal on the S4. Verizon has been super big on wireless charging. I can't see them going away from it here. But to never know.

Take it with a grain of salt. As these employees know nothing about the device. I find it humorous that they provide answers the questions that don't know.

Here is what I got from them

"Hello sbduce;

There will be a wireless charging door (Qi standard) for the Samsung Note 3 soon after it launches. The door will available for online ordering at www.verizonwireless.com.

Thank you for posting your question!"


I have trust issues with Verizon though so I am not sure if I believe this just yet. Going to wait and see what else comes to light this month.

I'm not a fan of spending $100 for the Samsung unit which requires putting a thicker back cover on my phone. WiQiQi made these for the Note 2, S3 and S4. Uses the original back cover by inserting a thin film with the charging coils under the cover and on top of the battery. I've never seen one of these but I hope they make one for the Note 3 soon. I don't know if the Note 2 unit would work since the battery pins have to line up and the Note 3 has a bigger battery. It's about half the price, uses the original cover, and should work with other charging pads such as the LG puck.

Can't imagine why they wouldn't. The aftermarket for the GN3 should be pretty good. I'm sure it is just some tooling to change the receiver to fit the new model. The base would not change

I wish the regular Flip Wallet Case had wireless charging :- / I don't like the S-View Cover Wireless because of more surfaces to keep clean and I enjoy the privacy the regular Flip offers (you can use it as a half opened book so that your neighbors can't see what you're watching.

I'm sorry, but this turns out to not be the case. The charging pins are both there and not covered by plastic. Below is a picture of my GN2 with the back cover removed.

EDIT: Ooops, Never mind. Those are the NFC pins.

Just for clarification, this was posted last year in another thread here actually (obviously in the Note 2 forum)

I think you are right. I'll keep an eye out for those. The S3, S4, and Note 2 units were originally on Indiegogo before they started shipping

I bought the little white wireless charging pack that goes inside the S4. Loved it. Wonder if the same pack will work for Note 3.

My only issue is I often will want to be performing battery intensive tasks while inductive charging. As I have experienced from my old palm touchstone mod with an output of .5amp on my GS3 just having pandora running in the background led to a charge deficit. I only hope that inductive charging VERY soon supports 2+amp or I will never be able to turn that beast of a screen on for long and hope for a charge.

Samsung has released pictures of a flip cover with wireless charging built in.
I'm more concerned about the non-flip cover with wireless. Adding the receiver coil to the back increases the thickness of the back. On the S4 that means most cases won't fit with the OEM wireless charging cover. Using a third party Qi adapter inside the standard back causes a slight bulge that also interferes with fit of many hard cases because there isn't enough room inside the cover.
I think the S3 and Note 2 may have had a little more spare room inside than the S4. Because of the designers pushing for ever thinner phones we'll probably have the same sort of issue with the Note 3.

Slightly off-topic, I have the OEM Qi charging back cover for the S4 and I like the way it protects the camera. The standard back lets the camera lens touch the table when you lay it down, and I got a minor scratch in the first few minutes I had my S4. Once I changes to the Qi charging back the camera was recessed just enough for protection.

    Hi Guys,
    I was one of the users who investigated and found the Note 2 has the QI pins present, but not enabled by the TMO processor variant. Regardless, there was a mod made for it and I later released an updated process that turned out to be a little easier.

    This morning, I decided to investigate the N3 and I can confirm (as it has been discussed here already) the TMO Note 3 does in fact have the QI wireless charging enabled out of the box. However, as discussed, that means nothing if there is no receiving pad in the rear casing area to convert the inductance signal to the required 5VDC feed. As shown in this thread, you can use a modified Note II receiving pad, but I found the stock setup to be a little bulky and the rear case seems somewhat "humped". So out came the soldering iron, siccors, and some patience.

    First, regarding the pins above and to the side of the battery, a few of the observations already made by others are correct -

    (2) pins above the battery = NFC

    (2) of the (3) pins to the left of the battery = QI Wireless charging [ pin1= + / pin2= - ]
    (The 3rd pin appears to be an external current monitoring/future use pin)

    With that out of the way, let's rip apart a stock N2 QI pad! I will use a 5VDC 1000ma N2 pad, which is rather thick at 1.75mm. But, with the two sides removed (hot blow-dryer/heat gun is your friend), the height is reduce to near 1mm. (tip - carefully cut/save a 3mm x 5mm section of the foam padding as we will use that later).

    qi_n900t_b.jpg


    Since we have to "flip" the layout of the QI pad, I proceeded to do the following in order to keep by the inductance coil as close as possible to the rear casing surface and remove the thick hump cause by folding the contact pads copper trace over (proceed only if you have experience with a soldering iron and electronics in general):

    A. Cut a horizontal slit in the protective laminate layer just below the area the oval inductor sits on (and above the little copper PCB area) so the oval inductor can be CAREFULLY slid and flipped to the opposite side without messing up to two leads.

    B. Cut off the pin contacts laminate section so it can be flipped as well and soldered back together(now facing the opposite direction and on the top/left side).

    C. Trim the remaining surface area around the pad perimeter to insure the pad stays within the battery cavity section of the rear casing. A Quick placement/fit test on the battery side is done to insure all is well.

    qi_n900t_c.jpg


    Once confirmed functional, the pad circuitry can be properly placed on the rear cover plate and secured using one of the previously used cover-stickers (the one without the padding). If needed, place that 3mm x 5mm foam cushion you cut earlier under the area of the pin contacts to help keep a secure connection when the casing cover plate is reattached.

    qi_n900t_d.jpg


    The final test is to see how everything does after the final assembly is complete. I use the Samsung OEM wireless charger, but any QI standard charger should be fine.:D

    qi_n900t_a.jpg


    Lastly, it seems the stock kernel limits the wireless charge current to 640-650mA, which is expected. Hopefully, when a custom kernel is released, the current limiting will be removed and allow it to go up to 990-1000mA with this specific pad like the Saber variant did for the Note 2.

    Hope this helps and sorry if I missed anything or wasn't as detailed as I usually am. It is a nice Sunday here in San Diego and I should be outside with the family!

    Cheers,
    Scott

    Observations on wireless charging for Note3 & S3 on Tylt VU

    A month ago I was even more excited to receive my Tylt VU than when I got my Note 3 in hand. This is because I was fascinated with wireless charging right from my S3 time to be able to charge it without the need to plug and pull wires from these hungry devices. But lack of reliable accessories made me to wait until this long.

    More than receiver stickers on battery I thought OEM φi compatible cases are more reliable and long lasting. Reading through the positive reviews and few other misleading articles about Samsung S-view flip cover for Note3 having wireless charging capabilities I was all happy with the slim and decent looks it added to my N3 along with its s-view sensors until I received my Tylt VU.

    20131226_115253.jpg

    img_20131226_120153-001.jpg



    To my biggest disappointment I see nothing happens on my Note3 with S-View cover when placed on Tylt VU. Being on a custom ROM I even tried my S-View on another N3 with stock rom, still no signs of charging. I was so confident about my Tylt VU that I started shouting at the seller who sold my S-view and also at the Samsung customer service for denying to look into this defective case under warranty.

    After careful reading I realized how much I was fooled by Samsung cheap sales trick to sell non Qi version of its S-view covers in India. You will hardly find any difference between these two versions of covers unless you know 5 pins are required on the inside of this case for both wireless charging and s-view functions unlike two pins for just S-view sensors.

    See the difference yourself

    https://www.samsungindiaestore.com/Products/Accessories/Note3_S_view_Cover_EF-CN900BBEGIN (Without wireless charging support)

    http://www.samsung.com/za/consumer/mobile-phone/mobile-phone/galaxy-note-accessories/EF-TN900BBEGWW (With wireless charging support)


    I can understand the seller for not having idea on these identical duos, so asked my apologies for shouting at him but the service center guys they are pathetic as they dint even know what it means by wireless charging.

    This time I ordered two battery receiver stickers for N3 & S3 and another built-in receiver replaceable back case for S3 as a backup. I thought I cannot use my S-view case anymore when I stick the wireless receiver on the battery covering all the 5 pin holes so I ordered a SPIGEN SGP Ultra Fit Case.

    In a casual attempt I tried fitting the S-view case over the wireless sticker and to my pleasant surprise I see both S-View and Wireless Charging works now. I think the pin could touch the contacts right from the back of battery sticker to make everything work.

    Looks like Tylt VU is worth the extra bucks spent on it as it charges in any angle the phone is placed. I don’t have to be so conscious in the middle of the night If I have to place it back on tylt VU it charges without missing it. It even charges N3 through my Spigen fit case with ease.

    Some facts and figures from my testing with Note-3 using different charging sources.


    Using Note3 Samsung Charger (Output Current – 2000mA)
    Charges at 1200mA

    2013-12-25-23-44-30.png



    Using S3 Samsung Charger (Output Current – 1000mA)
    Charges at 900mA

    2013-12-25-23-45-07.png



    Using Tylt VU Wireless Charger (Output Current – 1000mA)
    With battery sticker charging efficiency lying between 60-75%,
    Charges at 640mA

    2013-12-25-23-45-37.png


    On average my Tylt VU charges Note3 at 20% per hour taking around 4.5 hrs for a full charge.


    Using Laptop connecting with USB2.0/USB3.0 port
    Charges at 450mA

    2013-12-26-14-45-12.png



    I could make my Note 3 charging at 1800mA for few seconds second by placing it on Tylt VU while it is connected to its 2000mA power charger.

    . . .the continuing saga of "what is the best wireless charging / NFC for use with the Otterbox Defender case?'. . .

    The newest configuration I am running is with the QI/NFC circuit from the OEM Samsung charging back, fitted to the stock Note 3 back cover.

    After separating the circuit card from the OEM charging back, I was able to carefully remove the actual circuit from the plastic card, leaving me with the fantastic OEM Samsung QI/NFC in a package just as thin as the white Amazon QI card I'd been using for the last couple weeks.

    I mounted the circuit directly to the inside back cover so that I could remove the cover and/or battery without disturbing the card, using clear 3M paint protection film to mount the card - this protects the circuit, and holds it all around the perimeter. (The thin metal 'T' on the OEM card is a heat sink for the IC chip).

    The first 3 pictures below are views of the back cover on, showing the very slight deformation from the mounted circuit card - fits snugly inside the Otterbox Defender case, but without any issues - and that is with my iLoome tempered glass screen protector on as well.

    The last picture shows the OEM QI/NFC card mounted to the inside of the back cover of the Note 3.

    Both the wireless charging and the NFC have been thoroughly tested with this newest setup - and they work like a charm!

    Cheers'

    Ultra-thin 0.5mm Qi Wireless Charging Receiver Card Coil for Samsung Galaxy Note III 3 N9005 N9500 with Full NFC Support

    Picked up another Qi Receiver that arrived today. This was purchased from Amazon from the link: http://www.amazon.com/gp/product/B00GFGL0XE

    It was $21.99 and had free shipping (I used Prime but paid $1.99 for next day)

    It is advertised as: 0.5mm and it is easily the thinnest of the Receivers I've physically seen so far, but might be a tad bit thicker at the chip. But it is still very slender. It has 2 pins on the side for the Qi connections, and 2 pins on top for NFC support. The chip itself is near the top of the card and sits just under the camera. The back cover of the phone however fit as flat as the TechMatte that I did a review on.

    Some pics:

    The box and the card taken out (there are no instructions but it is fairly easy for even a very novice user to figure it out)

    Hv7kpTKl.jpg


    Other side of the box:

    rLFIx1Dl.jpg


    Cover side:

    sa22ZR5l.jpg


    Battery and connector side:

    9yM5TNsl.jpg


    Unlike the Techmatte, there are some differences:
    • Slimmer
    • No cover side connectors that you could use for say the s-view flip cover
    • Has NFC built in and and works well

    Will add pics of it inside the phone when I get my other camera out.

    Oh and it appears to charge just fine. I was seeing 640mAh when I checked it with two different apps to check.
    5
    Last night I charged 1st time the phone with QI, and I'm totally fine of the time that was 4 and something hours from 15% to full. Also I was checking every now and then the temperature with a laser thermometer between the backplate and the base because I was afraid that the coil maybe was somehow hot (I never had used a wireless charger in anything before) and temp was max at 38C so all are good in that area.
