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.

ok cool;
but.
i did the mod for the s3....... twice.
it didnt work out; so id rather just buy a pre-made module; do you know what one i can use fro the 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 is not easy for nomal people to change the phone like this. if there's no official support,
most of people will not care that.
although , i like wireless charging very much

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.
Oh false information from people that don't know what they're talking about ¯\_(ツ)_/¯
Im not sure if there's been a new development on this or not but I didnt get find anything.
These Qi Receivers like:

The qi wireless charging mod seems a little too complicated. Now that we have these receivers has anyone tried fitting one to the S2?
I know they arent made for it and there are special connect points in teh S3 S4 and the such but cant an end be splayed open and put in between the 1st and 4th connectors where the battery makes contact with the phone? It would be a little difficult to force fit it but it would be snug and not likely to move and fits over the battery well. Has anyone tried any of this?

Qi Wireless Charging
Hi, I just bought a Qi Wireless charger & Charging Cover and its pretty cool! I bought it from the Bitmore UK site.
They have a wide range of Qi (wireless charging) Devices and the one I bought for my S3 is universal. You can charge any qi enabled devices on this pad.
Just search for: BITMORE Qi Charger
Hey guys, Is there a Wireless Charger for Galaxy Tab S 8.4 or the 10.1 model? I tried searching but I keep seeing Qi Wireless Charger supporting most of other android device except Galaxy Tab S. Please do let me know ( link) if you found a wireless charger for your Galaxy Tab S. :fingers-crossed:

The Galaxy tab does not support Qi charging built in. To only way to support wireless charging would be to add a universal micro USB Qi receiver such as the one in the link below. However based on the size of the tablet, not sure if this would even work well due to the position of where the receiver would sit in comparison to the charger. Personally, don't think it's worth it on this tablet.

There is a reason, which is to reduce the wear and the chance of breaking the usb port. 2 different phones I was able to keep using for a year after the usb port broke because I had hacked in the receiver from the Palm Pre. There was no way (for me, without more exotic equipment than a fine tip soldering pen) to re-solder the usb port. Too much stuff crowded around it and it was surface mount. But I could get 2 wires on to the ground and +5v easy.
Warranty isn't an option unless you never rooted, so that leaves having to be very careful never to break this weak point for the next 5 years.
Myself, I can't see sticking that thing on mine either, I'm just saying that there are reasons one might want to and it's not automatically ridiculous or pointless.

Don't get me wrong, I love wireless charging and have been using it for a couple of years now on my phones. I also thought about it for my LG G Pad 8.3 tablet. However don't think its a good option for the 10.5. Reason is as I mentioned, positioning. Most chargers are small. Positioning the tab on it may prove to be challenging due to sign. I think it would end up leaning off to one side and not being able to get in a good position. Thus would be frustrating. I think the 8.4 would stand a better chance but not the 10.5. Just my opinion anyway.

You could probably just put the charger on the tablet in that case. It's also perfectly possible to make your own tray that has the charger embedded in it.
For devices too large for the charger. Cut a piece of cork(same thickness of the charger) to the size of the largest device that needs charging. Cut out a hole to imbed the charger into the cork. Cut out a hole in the end of the cork for the charger power cord. The end result is the charger and the cork will provide a nice flush surface to charge any size tablet.
An easier way to charge tablets is to lay the tablet face down and set the charger upside down on the bottom of the tablet.
QI is designed for phone
Guys,
Ive been charging my tab (had a couple.. current one is Samsung Tab A) for years.
I simply buy a charging receiver with a USB connection. Plug it in, tape it onto the back and away you go...BUT...
USB charging receivers are designed for phones. 2000, 3000mah batteries so a charging input of 1000mah is ok. The tab battery is 6000 so a 1000 charger is Slooow
Most USB (wall) chargers are 1000mah and/or 2500mah.
wish someone would make a 2500 qi qharging receiver.... then life would be much better.
Even thought of updating my tab so I have faster CPU and USb type C connection... problem is QI for USB-C is also only 1000mah... WHY???
Faster charging would be much better

Hi,
my fried have Samsung Galaxy Ace 2 GT-I81160P and we found some kind of antena in cover with two copper contacts, that fits with two contacts on phone back side.
Is it only some kind of antena extension, or is it antena for wireless charging?

And if it is a wireless charging antena, what charger should he buy to be able chyrge his ace2 wirelessly?
Thanks

- Nice one.. NO - this is of course not wireless charging - This is the NFC (Near Field Communication) Antenna
NFC is the P in GT-I8160P - The Phone without is called GT-I8160 (without P)
I have a ZeroLemon battery and a Samsung Universal Smart Dock. I can't fit my phone into the dock with the ZeroLemon battery, so I had the idea of using an extension cable. I've read on at least one account, that one of the cables I was looking at, the connector on the cable was not deep enough for Samsung phones. Is there any truth to this?
Anyone who uses the Smart Dock and has tried an extension cable, which one have you found to work well, not necessarily with the same battery, but in general?
