Hi all,
Here's my 5 minute wireless charging mod. Now new and improved so that NFC performance is not affected at all. I've also posted step-by-step pictures to aid in explaining the hack.
You need to make one decisions before you start, do you care more about using NFC or using a magnetic compass app? The reason for this is that the magnetic sensors are in the bottom part of the phone. If you use magnets instead of metal disks, this will affect the accuracy of the magnetic sensors, so a compass app will not work well. But if you use the metal disks that come with the Palm case, and you do the hack with the coil very low in the phone case, it won't hold through a case, so you may need to build some sort of rest for it. I use NFC all the time, and never use the compass, so decided to go with replacing the metal disks with N42 magnets. Also, this charging mod works fine through most cases, I've tested it with TPU and with the Rock cases. It might not work through an Otterbox, I haven't tested it. Using magnets makes it more likely to work with cases. Alternatively, you could use the nonmagnetic disks, but rig up some sort of support so that the phone would sit in the right place on the charger without depending on magnets.
No soldering, no carving, the only tools you need are a knife, and some scotch tape! Some sort of plastic tool, even a plastic knife is helpful too.
The shopping list is below, and totals about $17-$19 depending on which vendors you buy from. The links below are from Amazon, for simple one-stop shopping. You may want to buy two Touchstones for home and office. I wouldn't try to cheap out and use another AC adapter, as most of the adapters I tried failed to work with the Touchstone base.

Okay, here's what you do.
Picture 1: Shows the Palm Pixi charging case as you will recieve it. (I recommend the Palm Pixi, not the Palm Pre, as the polarities are reversed on the Palm Pre.) After you get all the parts, gently peel the black tape off the Palm pixi case, (Picture 2 and 3). Then gently and carefully remove the circuit board (Picture 4), the silver metallic tape (Picture 5), the coil (Picture 6), and metal discs. Preserve the silver foil tape, you will need it. You may also want to preserve the black tape.
Next, I show that you can make a template for positioning the coil and discs/magnets by cutting up the Palm Case (Picture 7), and then drilling out holes where the metal discs and the center of the copper coil are (Pictures 8 and 9). I then made a paper template, which is easier to use (Picture 10).
Now here's the clever part of the hack. Put the coil into your Samsung battery cover upside down, as shown in Picture 11. Then fold the L shaped flexible circuit board up as shown in Pictures 12 and 13. This positions it so that you can make an easy connection to the phone using just copper tape. You will run small pieces of copper tape from the top and the bottom power terminals, which are those little square metal terminals shown in Picture 13. (Picture 14 and 14-5). You can then position the discs or magnets. The easiest way to do this is to plug in your Touchstone base, and then lay the back cover on the Touchstone charger. Put your magnets or discs in, and make sure they align with the magnets in the Touchstone base. Note that if you use magnets, you may have to flip them to get them into the right orientation. Use the template you made to check the alignment. Once you get it like the picture, just tape everything down with scotch tape. (Not the terminals.) (Picture 14-5 shows this clearly.) Note that you need to put back in the silver tape over the coil as shown in Picture 14-5, otherwise it won't charge.
Cut the copper tape down to about 1/8 of an inch, and tape two extensions from the charging terminals in the phone. I used a pencil to poke the tape down into the little wells so there was a good contact. Next, lay down the cover and the phone, and tape copper tape to the charging terminals on the charging coil so they will hit the tape on the phone when you close the cover. I folded under the final 1/8 of an inch to make a little lump, to make it more reliable. (Picture 16).
It's useful to check your work with a voltmeter. Place the battery cover with the mod onto the Touchstone base, and check to make sure you are getting 5.5 volts off of the two terminals. Then after you add the copper tape extensions, make sure they are reading the same voltage. If you are not getting voltage, press the tape harder onto the terminals, as the sticky side is less conductive. You could also fold over the copper tape onto the terminals, and scotch tape it down.
Finally put the back onto the phone, and test to see if you get the popup message in Picture 19. If all is good, then you can open it up again and add back the black tape to make it pretty (if you care). (Picture 15). Then should be no real bulge as shown in Pictures 17 and 18.
If it's not working, there are three possible reasons. One, you have a bad connection between the terminals and the copper tape. Check it with a voltmeter. Two, the copper tape that goes into the phone's charging terminals is not making good contact. Fold over a bit of the tape, and gently jam it down into the terminals. (Gently so that you don't break them off!) The third reason is that the tape pieces from the coil are not making contact with the pieces on the phone, see Picture 16 for how the alignment should be. If you are getting the popup repeatedly, then you have an intermittent connection.
Oh, one more thing. Be sure to test this with your phone at less than 100% charge, as it won't work if your phone is 100% charged! I found this out the hard way!
Close the cover and you are done! It sounds complicated, but actually if you just copy the picture, it takes 5-10 minutes.
Here are the pictures, numbered as in the instructions:

Thank you's appreciated.
A FEW UPDATES: Here are a few updates from clever ideas from our members.
You can use hotglue to attach everything once you are sure of the location.
The disks in the Pixi cover are metal, not magnets. Replace them with magnets for a better hold.
The magnets (and the coil) could go in a case like an otterbox, instead of inside the phone. Then you'd run thin wires into the battery case. Or you can run the copper foil out from inside your phone so that it connects with the mod inside the case. See post #217 for a way to do this elegantly.
BE aware, the Palm Pre polarities are reversed, so if you use a Palm Pre back, you will have to reverse the polarity.
IF YOU AREN'T GETTING VOLTAGE:
The most common problems are:
1. You are not using a palm charger and cable for the Touchstone. Most chargers/cables won't work, it's better to just use the Palm charger, they cost $4 on Amazon. Are you using the Palm charger/cable?
2. Your copper tape is not making good contact with the little prongs on the flexible circuit board. Try removing the tape and checking voltage on the prongs themselves. Then put the copper tape on firmly, and check the tape for voltage.
3. The coil is not in the right place. You may want to make a template like I suggested to get everything aligned properly. You won't get voltage if the coil is not just right. Use scotch tape to get everything working, then you can use more permanent methods.
4. You used a Palm Pre back instead of a Palm Pixi back, and you forgot that the polarities are reversed on the Pre back.
5. You are not getting a good contact at the charging pins on the phone. Do this: (thanks nonsns3)
Cut tape a quarter inch wide. Ball up a quarter inch on one end and tape it so that the ball is right above the connector pins. Also make sure the exposed part of the ball is not the sticky side. Using a pen, push the ball end into the hole so that it contacts with the pin and you should be all set. This should be the easy part.
Most of the time the two issue areas are:
1) copper tape doesn't make good contact with the pin on the back cover because one side is adhesive.
2) copper tape doesn't make contact between the back cover and the copper tape on the phone itself when you close the cover.
FAQ:
Can I charge the regular way with a micro usb charger after I make this mod?
Yes, it works fine. Just don't plug in the micro usb and the touchstone simultaneously, as I don't know what would happen.
Should I use magnets in the mod instead of the metal disks?
It depends on how thick a case you plan on using, and how firm a grip you want the phone to have on the Touchstone base. You can always use scotch tape and test it both ways.
Will this interfere with NFC?
No, typically it won't, and you can decide on the placement of the mod over the battery, or below the battery. Below the battery has no effect on the NFC, over the battery makes NFC a little more finicky about positioning.
Will this interfere with my compass app?
Only if you use magnets instead of the stock metal disks. And then only if you put the mod low in the battery cover, as the sensors are low down.
Will this interfere with GPS?
Absolutely not.
My phone slides off the Touchstone base, what should I do?
I've modded my bases so that the top is horizontal instead of sloped, which makes phone alignment easier. I used Sugru, but any substance that allowed you to fit in the bottom will work.
Everything was working great, now it stopped working.
Usually the reason is that you've dislodged some connection inside the phone. If this happens, just open up the battery cover, and check all the connections, especially where the copper tape meets the charging terminals inside the phone.
Should I put magnets onto the Touchstone base?
Yes, see my attached picture, this helps with a firmer grip, and may even obviate the need for using magnets inside your SG3 case. Note the magnets can attach two ways depending on their polarity.
I find the charging noise annoying, especially after the phone is fully charged, and it keeps beeping at me.
Yes, on some ROMs this is very annoying. To fix it if you have root, use Root Explorer to got to /system/media/audio/ui . Then press the button on the top right that says, "Mount R/W" so you can change the files. Find Charger_Connection.ogg and either delete it or if you might want it back, just rename it to Charger_Connection.ogg.bak . Reboot, and no more noise, but be sure you see the charging indicator on the phone since you won't hear a beep.
I am considering doing this but with a twist. I would put the coil between the otterbox rubber and hard plastic and put the wires though a hole in the battery door. I would probably have to cut or thin out the rubber so it would fit flush, but I am confident it could go through the fairly thin otterbox plastic.

This seems like a cool idea but whats the point if it needs to stay on the touchstone? (If im correct on that)
Nice work. I really like this and will be doing it as soon as I get money for the parts. Thanks for sharing

I'm pretty sure all wireless charges have to sit on their charging bases. The simply alleviate the need to hook up cables to you phone (which could as to the life of the phone considering how many times you'll be plugging it on over the next year or two).

Just curious. Does this mod interfere with NFC?

The point here is to eliminate the foolish cases that wireless chargers have to equip your phone with to work. This is one of those amazing things that this site has to offer. Fine work my friend!

Okay, here's what you do. After you get all the parts, gently peel the black tape off the Palm pixi case, and remove the coil, and magnets. Preserve the silver foil tape, you need it. Mark the top of the magnets with a marker, and gently dig them out with a knife. Don't break them.
Pop open your Samsung Galaxy S3.Lay the back cover on the Touchstone charger, and put the magnets in the same orientation they were in in the Pixi cover. If you flip the orientation, they will be too close together. Then lay in the coil, with the tape extending up to the right. Make sure there is enough room to add the copper tape later. You may need to slide the cover so the magnets are slightly to the left.
Once you get it like the picture, just tape everything down with scotch tape. (Not the terminals.) Cut the copper tape down to about 1/8 of an inch, and tape two extensions from the charging terminals in the phone. I used a pencil to poke the tape down into the little wells so there was a good contact.

Close the cover and you are done! It sounds complicated, but actually if you just copy the picture, it takes 5 minutes.
Several tips:
I actually replaced the magnets with some that were a little more powerful, but you can get away with using the original magnets.
If you want to have a more finished look, you can use the black tape cover from Pixi cover to cover over the mod, but I'd tape it first, and make sure everything works.
Here are the pics:
Thank you's appreciated.

Wouldn't those magnets mess with the phone's magnetometer thus things like the compass? I wouldn't see a problem to do away with the magnets and just put it on a regular wireless charging pad so there isn't a need for the magnets. Other than that issue, kudos for the directions for such a cheap mod :good:

Hi,
I just tested it with Smart Compass, and it seems to work. How many people use a compass app anyway? Don't most use GPS, which isn't affected by the small magnets.
In terms of NFC, I haven't tried NFC, so I don't know. But other's who've used the same system don't have problems with NFC. You could always mount the coil lower, so it wasn't near the NFC chip.
I don't understand the question about the phone needing to stay on the Touchstone. How is that different from the phone needing to be plugged in while charging? The major advantage of this mod is that a) it's way cheap and way cool, and b) you won't wear out the micro usb port plugging in and out. Also, I find it much more convenient to just lay my phone down on the charger whenever I am not using it, so it's always fully charged.

That would work, although with slightly stronger magnets like what I used, my phone has a Rock Case on it, and everything works right thru the back cover and the Rock Case.
Ahh I see, not worth it to me, I use my phone while charging a lot.

Glad to hear this works through the Rock case!
I already had all the parts you listed in the mail before you started this thread, and my biggest two worries were:
1. Slight bulge from coil might prevent Rock case from fitting
2. Rock case will prevent this from charging
Great to know neither of these will be a problem!

Last time i checked the 'magnets' in the palm pixi cover are not magnets but small pieces of metal. The magnets are in the pixi charging pad. I did this mod a long time ago and just used some really really small wires to complete the connection, i have been meaning to buy the copper tape but, lazy.
Nice mod!! If you could post a vid of a tutorial that would be sweet!??? I have always been the type to learn the best by watching it in action... Great job though!!:good:

No, they are small and thin neodymium magnets. What phone did you do it on "a long time ago"?
Ordered
Just ordered the parts. Touchstones for $3.50 and back covers for $3. Makes me sad though to see how Palm has fallen. My wife had a Pre Plus and touchstone and we both loved that phone. Probably would have bought a Pre 3 if they had ever come to market. Got 2 touchstones so I can have one at work. I will most likely epoxy the components to the battery cover since new battery covers are like $5. Should hold up better than Scotch tape over time.
Will report back when I get it all working.

That's a good idea, maybe I will have two covers, one with wireless charging for most of the time, and maybe one plain one for travel, etc.You might want to play around with it a little first, using scotch tape, check out NFC, etc, before you commit to gluing it all down.
Can you post a video that would be really cool
Sent from my SCH-I535 using Tapatalk
F***ing brilliant
For those looking to glue & not use tape just use silicon as it is easy to remove with no damage if needed but more stout than tape
This is awesome, thanks! The cover fits after gluing all that extra stuff without a problem, right? And how fast is the wireless charging?
Hi,
I've got my OnePlus 6 for 6 months and USB type C became loose. When I plug in original OnePlus 6 cable It just sticks rather fine, you can wiggle it for a little in a port. But sometimes when you move it slightly to the right Fast Charging changes into Regular Charging. But the best part comes when I try other cables than stock one. When I plug in non stock cable it charges fine (regular charge) but when you move it slightly it just pops out on its own. Additionally sometimes it pops out from its own after some time of charging. When I plug it in into a computer, phone just charges so I have to bend it to the right for OnePlus to pick up USB connection (Stock one works fine).
I'm worried, because stock cable is becoming loose too.
I've never charged it in my bag, pocket, etc. Just laying on a flat surface without any cable bending.
I'm worried that OnePlus 6 has low quality connector (Cuz it's not normal to start failing after 6 months). I can repair it on my own by buying new port, but It shouldn't be the case with new half year flagship phone
Cables tested:
Stock OP Cable
2x Unitek USB-C 1.0m
Skross USB-C 1.0m
(They work and stick great to other phones with USB-C cables (Testd on Oneplus 5t and Huawei p20 pro so it's problem with Oneplus 6 Port).
Do you have similar problems? Or should I just return my OP6?
No issues here, don't do it yourself. Send in for repair.
Maybe there are some dirt and dust inside or the pocket things, try to clean is with a toothpick or something non metal
I'm suffering from the same issue. Cleaned it out as best as I could and seems a bit better, but loose nonetheless.
Okay, fixed it
Checked again USB-C port (I was cleaning it recently, like 2 ago) aaaannddd while in fact both sides of USB-C port were clean (I mean sides separated with this thin inside connector thingy) , but in a very bright light I saw that places where are curves were gunked up badly.
It was a little pain in the *** to remove dirt and dust from curves, because there's no much room there (Was using flat, plastic toothpick which fortunately could flex into this spot)
And cleaned the curves
Now for the very first time all of my USB-C Cables clip nicely into the port and stick in very hard (Now I kinda have problem to plug out cable XD).
Thank you all for your support! I think we can close thread now.
Protip for future: Check curves in the port in a very bright light
I know this is old, but it came up at the and I thought I'd chime in. I spent 30 minutes+ removing the lint which was compressed very deeply in my OP6. That's the problem, it's so compact it's almost solid.
You need to (carefully) shave a toothpick right down with a knife and a wooden board so it's as thin as you can get it. I also used a shaved plastic tooth flosser, as it had a little hook.
For satisfaction, I suggest putting that lint onto a surface so you can see the workings of a huge bundle appear, and understand what really happens.
Oh also, using a phone with a good camera/zoom and a torch also helps to see just how bad/excessive it looks. Or a magnifying glass and a torch.
