Wireless charging confirmed working on our T-mobile S4

Hey guys, don't know if people have done this already, but I just got a T-mobile S4 for testing this weekend and I wanted to find out if the wireless charging port was enabled since I've done the touchstone wireless charging mod on my S3 and note 2.
It was especially a PIA on the note 2 since T-mobile, in all of its corporate and engineering wisdom, decided to disable the feature for the Note 2, even though it was enabled for the S3. So for those of you who don't like to dissemble your new phone and solder on a tiny PCB, you'll be happy to know that I confirmed that wireless charging ports on the S4 is indeed enabled.
I took a pack of 4x AAA battery assembly, which provides ~4.7v of DC power, and connected to the charging port in the back. The small pair on the left is the charging port, the pair on the right is supposedly NFC, even though the NFC antenna is located on the battery for S4.
As you can see from the pics, the "the phone is now charging wirelessly" notification pops up when the circuit is live, which is pretty annoying IMO and can't be disabled (that's why we have custom roms right?)
I haven't gotten a chance to install the actual touchstone wireless charging receivers on the back yet, as this is a test unit that I have to return, but I don't imagine this to be too different than on the S3. There will be a slight bulge, but it'll be worth it.

How do I put this mod in use

Tried it with my Qi charger from Energizer and it's doing absolutely nothing.

Just follow the instructions from this thread (it's for an S3). The design for S3 is pretty similar, so it should work. Remember the positive pin is on the left, negative (ground) is on the right.
Also note that the touchstone mechanism is not Qi compatible, so it wont work with the newer charging mats for Nokia or HTC.
And always remember to perform these mods at your own risk.

Did you install any receiver on the S4?
I didn't mean to confuse anyone, I only confirmed that it is POSSIBLE to perform the mod. I used a 4.7v DC power supply to test if the wireless charging pins on the back are live, which wasn't the case for T-mobile note 2 so I had to check to make sure.
If you already have a Qi charger, you can get one of these receivers and connect it to your phone, then you'll be able to charger with your mat

But I would argue that the touchstone method is superior to qi if you plan on using it in a car, as the magnets keep the phone in place is it's really convenient to connect/disconnect when you're driving.

Samsung will be officially supporting wireless charging for the S4 through accessories. The ad for the pad and back wireless charging cover is already listed on the promo S4 accessories page. http://www.samsung.com/global/microsite/galaxys4/
Though there seems to be no price or date yet.
Of course there will be 3rd party wireless charging solutions as well.

ive got a palm touchstone but what receiver do i need to buy to have my GS4 work with it ?
also;
can anyone confirm or deny wether or not the palm touchstone + receiver will trickle charge the GS4 after it is fully charged ? (or does it completely cease charging until the phone is physically picked up and replaced ?)

the link above is the thread with a tutorial on how to do the mod for S3, should apply to S4 as well.
I can confirm that it trickle charge S3 and Note 2 ( if I understood you correctly, it will keep the phone charged as long as it's on the touchstone base), shouldnt be any different for S4.

Took the Qi wireless receiver pad from my Galaxy S3, had to slightly tear it apart to reverse the little gold inserts that create the contact points for the wireless battery charging and now have a fully functioning wireless charging Galaxy S4 !
Saved myself quite a bit of money doing that.

It seriously only took 5~10 minutes once I'd figured out which way to put what.
I have the photos set up and just need to put notes on them explaining what I did.
Will post them when I get home tonight (12am CT)

Ummmm, from everything I read the pins you have it hooked up to are NOT the ones for inductive charging, the gold ones on the right are......
I could be mistaken however. I remember the s3 used those pins, but I've read in a couple places that the ones made specifically for inductive charging are the ones on the right above the battery.

What ARE all the other pins back there for? I figured one set (had no idea which one) was for inductive charging, but couldn't figure a reason for the others..

the smaller set is wireless charging, the larger set is presumably for additional NFC antenna (although I measured no resistance in the circuit with my voltmeter), as the back cover seemed to have a carved out area for a NFC like the Note 2 did.
Although the S4 battery says "NFC" on it, which seems like samsung made a last minute decision to put NFC on the battery instead of the back cover... oh samsung ¯\_(ツ)_/¯

Nope, the NFC is in fact in the battery, the same way Samsung has been doing it for years now. They made no change.

If you know it does not why would you start a thread? It makes no sense. It does not have a removable battery cover so there is no way to add wireless charging without hardware modifications.

Ok, thats new for me. But there is one chance. There could be a case with qi Receiver and usb connector or if it has pins for a docking station then with connection to them.

Have you popped the back cover off to see if the pins are there?
If they are then a modded qi receiver would work great.

I do not own the Note 10.1. Thats the reason why I'm asking dumb questions.
For the Note 8 someone added a Qi Receiver with USB connector and hide it under a case.

He is not talking about taking the back cover off. He is talking about a case that has a plug that goes into the existing charge port of the tablet and there is a wireless charging coil within the case itself.
No, I have not seen any.
Yes, I do want one.

Does the Note 10.1 2014 has Connectors for a Docking Station? If yes, this would be an option to realize it without using an usb connector.

It does not have docking pins.

I, too, would love to add wireless charging capabilities to the Note.
I read a story on the iQi Mobile - Seamless Wireless Charging For iPhone and tried to find a similar product for micro usb ports. I came across a possible alternative but don't have any experience with the website/seller of the product.
(sorry, can't post links yet, remove spaces or search Google for "netimes Qi Standard Universal Wireless Charging Adapter for Samsung Micro-USB Connector")
www .netimes.com/shop/qi-standard-universal-wireless-charging-adapter-for-samsung-microusb-connector-p-4963 .html
Do you guys think something like this would work?
One disadvantage would be that you would have to unplug the cable to use a regular charging cable, but I think I could live with that.

in my opinion this seems legit and ok.
Of course it's annoying to remove the cable everytime, but for having wireless charging
l already thought about this on my HTC Eo 3D but did not want to spend too much money on that since it is no Must-have in my opinion.

Qi Enabled Wireless Charger Platform & Charge Receiver Samsung Galaxy Note 10.1 2014
www .amazon.com/Walsontop-Wireless-Platform-Charging-Compatible/dp/B00LC6WGB2 There are still people looking for the holy grail. "Human satisfaction.

you can attach a receiving case to the note 4, so why not the note 10.1 (2014) ?

As Qi supports 15 instead of 5 Watt (since 06/2015), we only need to wait for the next tablet generation. I think in the future we will see Qi on much more tablets.

i think you are looking for this

No, because the quality is poor and it is qi 1.0. I think at the moment there are no qi receiver supporting qi 1.1?! And of course it would be much nicer to have a receiver built-in or under the battery cover.

Am I the only one that doesn't like qi charging? I have it and a pad for my nexus 5 and 7fhd and just don't use it that often. I use my phone often when it's on the charger and qi is much slower than the wire. I just can't see using it

Thats because you're using it wrong. I have 4 Qi pads and they are placed everywhere I stay for a longer time like bed, desk, couch, etc. By that its the most comfortable charging.
And if fast charging is the only reason you need to know that Qi released Version 1.1 with 15 watts (same speed as USB 3.0). But it seems Samsung bought exclusive rights at the moment (Note 5), so we need to wait for other devices supporting it. But I do not miss it.

I've seen the samsung galaxy charger duo which charges both the phone and the watch, and there are also a couple of alternatives on amazon if you search for duo wireless chargers

One of the main reasons I pre-ordered my Galaxy Watch here in the UK was that it not only came with the standard single wireless charger that everyone gets, but it also came with a free Duo wireless charger! The Duo is OK, though I'm a bit surprised it used micro USB rather than USB C for power and that the section to put your watch on isn't magnetic like the single standard wireless charger is (I guess it's not so critical because its horizontal rather than vertical).
Both charging areas of the Duo have "fast charging" written on them, though is the Galaxy Watch even capable of that? I think the retail price of the Duo (89 pounds in the UK) is scandalously high - it's probably worth about a third of that. Single Qi chargers can be found for 10 pounds or less, so to charge 9 times that for a Duo is ridiculous.

Im guessing your right, but im looking for an alternative that wont charge your phone wireless too (because the op6 hasnt got wireless charging though)

Same here, I have a Nexus5x (and no plan to buy a Samsung phone any time soon).
I might end up 3d printing a stand with usb-c for my phone. I just need to find some good Galaxy Watch charger for that.

I honestly wouldn't expect an Apple charger to be compatible with anything but Apple.

I was in a Samsung Store and they have the Galaxy Watches on Display on the Chargers that look Great.
I would like to know How and Where and How Much.
How can I find the Samsung Galaxy Watch Charging Display Stand that I can Purchase?
Where is it Available to be able to Purchase?
How Much is the Official Samsung Galaxy Watch Charging Display Stand?
If Anyone Know then Please let Me know.

Anyone found a dock station for OP7 and Samsung watch or similar?

Hi all,
I have the Samsung S3 watch which only allow wireless charging and I bought the OP7 knowing that it doesn't have wireless charging option, but I would like to have a dock station for both and I was unable to find a **** station or something similar that allow me to have charging both devices.
Anyone find something useful to get both together?
Thanks in advance!

Buy a wireless charging pad, stick it into your oneplus and put a case over it. Then you can wirelessly charge both devices
https://www.ebay.co.uk/itm/Phone-Qi...e&pageci=847d4dc2-94a9-4fe1-aa0d-bff2a0150403
You will need something like this costs you about 10 bucks

Thanks for the tip, bu before to add something "permanent" to the phone I would prefer to have something that fit my situation, but if nobody has seen something similar could be an option but I would have to buy a solid color case too.

Are you looking for something like this?
https://www.amazon.com/dp/B07NXRYZZG/ref=psdc_2407761011_t1_B07G2R3DR5?th=1

Hi,
Not really, because in that model I have to plug the cord on every device. I'm looking for something to connect like the Apple bases where you hook the phone and something to charge the watch.
The other idea to user the add on for the phone to charge wireless would be an option but I would like to avoid something like that as I usually don't wear cases for the phone and it would be like something sticky

Wireless Charging Pads.. Got any that work..

I have used the same old charge pads that I used too, and none of them work.
Does anyone have a combo that works, and could link them or help me out? Please..

Wait? Why are you looking for wireless charging pads for a phone that doesn't have wireless charging?

A50 does not support wireless charging. You need a glass back for wireless charging to be possible. The A50 has a plastic back.

Not quite right. It just can't be metal. Plastic works for wireless charging, but the A50 doesn't have wireless charging built in. (You need a charging coil for that.)
There are charging coils you can connect to the charging port to add wireless charging to a phone. I suppose the original question is if anyone knows of any of these that work with the A50.
Here's an example: Link (Don't know if this works with A50 by the way.)

Yeah I've seen those before, been thinking about getting one myself but I'd probably just break it lol, plus I'd like to take my case of now n then

No reason why it wouldn't work though... Unless you had a metal case... Which you most likely don't, but plastic is finee for wireless charging.

If you have never added wireless charging to a phone, thats OK, especially if you are new.
If you read that I looking for a combo that worked, it might become apparent that there is something going here you might not now about.
Laughing at me because because I was short and to the point, doesn't really help. Nor liking your own post too..
So its quite possible to add charging to this phone. Any phone. You add a coil with your charge socket type, and add it to your device. Place on a charge pad, and you are away.
Just so you know...

This guy liked it, not me ?

This one seems like a good option, it allows you to charge it wired without having to take out the wireless charging coil's cable, andd the charger is magnetic, however this also means it is not usb c and your existing usb c chargers won't work unless you unplug the wireless charging coil. https://www.amazon.co.uk/dp/B07MLRD1TD/ref=cm_sw_r_cp_apa_i_zMeEDbG6PW858
