***If this does not belong here I appologize, and feel free to move this if necessary. I just figured the development community is most likely to take this "upgrade" on***
After seeing that someone used Palm's wireless charger on their non-palm phone; I decided to put one on my Droid Incredible.
***This was done to a completely stock Dinc. I did not use any special back, and the stock back gets to stay on (unlike in the other video that I saw)
Wireless Charging the Droid Incredible
**Disclaimer: This will void your warranty, and if you solder something wrong will probably break your phone. With that said I can in no way be held accountable for anything that occurs while performing this “upgrade” to your phone.
>>>>If anyone knows where I can buy that little void sticker that you will see in a picture below, please let me know! If we can get that sticker then our warranty is not voided by doing this.
Supplies:
1.Palm touchstone charger http://www.shopping.hp.com/product/handheld/categories/palm/4/accessories/FB300AA%23AC3
2.Palm touchstone phone back http://www.shopping.hp.com/store/product/product_detail/FB306AA%23AC3?
3.Micro USB cable
4.Soldering Iron (the finer the tip on this the better)
5.Torx T6 screw driver
6.Safe pry tool (or a small flat head screwdriver)
7.Very tiny insulated wires (I just pulled mine out of a USB cable that I cut up)
8.Electrical Tape
9.[Optional] Multimeter to test that you actually made a good connection
How To (Images are of a higher quality (12mp) so I had to stick them in zip files to get them on here):
1.The palm touchstone phone back has a sticker inside of it that encases the wireless charging receiver, so you need to peel this off. Once it is peeled off it will look like this (without the wires soldered onto it):
(Images can be seen in: Palm Receiver.7z)
2.Remove the battery cover and the battery then unscrew the back from your phone (please view a tare down video for details, there are plenty of them on you tube that I used for a reference.)
1.All you need is a torx t6 screwdriver and a safe pry tool, I used a small flat head screwdriver and it worked just fine. Unscrew the 4 screws around the sides and then carefully pry off every place that the battery cover clips on, as they also hold on the red back.
(Images can be seen in: Dinc Inside.7z)
3.Solder on some wires to the USB connector as shown in the below image without soldering onto the pins next to them. This is difficult and takes some time and patience, since these connectors are very small and close (note the polarity in the image, notated in red).
A.Also it is necessary to place a piece of electrical tape over the components right next to the connector (Green box in the image) as they will short out the power and make it impossible to charge your phone if you do not (I found that out the hard way and went back and fixed it).
B.One final note here is that I had to melt down the red phone backing inside to allow the cables to get past the case. See the green rectangle in the image above for where I had to do that. I just used my soldering iron and melted it down, it makes a pretty nice indention for the wires to fit through.
(Images can be seen in: Dinc USB.7z)
4.Now push out the rubber plug in the red phone backing next to the USB cover (this is encircled in Green in the image from step 2).
A.Run the cables that you just solder on through that so that they are sticking through to the battery compartment on your phone.
B.You can also stick on the palm receiver to the inside of your phone cover (note the direction and placement, as this is necessary to close your cover).
3.Note that I placed electrical tape over the wires. This was necessary to keep them from breaking off of the USB connector since the solder points are so small.
(Images can be seen in: Almost Done.7z)
5.Solder on the wires to the palm charger receiver and you are done. Now you just need to carefully place the wires towards the middle of the phone so that you can close the back of your phone entirely (this is another reason why the wires need to be small).
A.Note the polarity of the connection.
B.Also I put a piece of electrical tape over the connections on the palm charger receiver to protect them (not shown in the image).

This could be truly amazing. I can't wait to see more.

Its been done with the Evo, but don't know anyone who did it with the Inc.
http://www.goodandevo.net/2010/06/h...rk-with-palm-touchstone-wireless-charger.html
Sounds really nice. Not gonna try it with mine because I'm too scared
Though shouldn't this be in accessories or general?
What are you doing to align the coils? My biggest concern that's kept me from this is the magnets also would mess up the compass sensors readings which I for one actually value.
Wow, you managed to bring me out of my months of silence in posting...
I feel honored that I can get you out of your months of silence
The coil alignment is handled by the magnets inside of the palm touchstone charger itself (the base unit that plugs into the wall). The metal objects that you can see in the "Palm Receiver.7z" file are actually not magnets, but small circular pieces of metal that get pulled towards the charger base when you get them close to each other. So when you have the phone off of the charger, there are no magnets to mess with anything
Also you will notice that there is a piece of metal behind the coil, and that seems to block the inductive signal all together (because I tried to put it on backwards to no avail). Therefore your phone is mostly protected from the inductive transmission.
The only thing that I noticed, is that the touchscreen on the phone is a little weird when it is on the charger, but I see the same side effects when plugging the phone into a "non-htc" charger (before performing this "upgrade"). **I also saw this on my Moto Droid when connecting it to a 1 amp charger, and I have seen this with multiple other touchscreen devices so I think it just has something to do with the frequency of the charger.
Also in case of any concerns: MY PHONE HAS IN NO WAY BEEN DAMAGED BY THIS "UPGRADE"

Yah, it probably should be, and may get moved (which is perfectly fine by me). I put it in here because I am a developer and much more likely to do this, so I figured the development community would be more interested.

I have a rubber case on my Dinc... would I need to remove it for charging?
___________________________________
Yup.... The ones yoe momma told ya about.... Bad Seed Customs!!
I think you will be ok if it is one of those thin (about 1mm thick) rubber cases. Anything thicker than that and you would probably have to install the wireless receiver on the case itself and remove your battery cover all together.
I tested a thin rubber case that I have (no more than 1mm thick I think) that fits a Droid Eris and it charges as long as its flush to the back of my phone.

Wow, this is amazing, very well done. I think this is the first hard mod I've heard of for an Android. I guess gold cards were a sorta gray area.
I've had my Incredible modded to work with a Touchstone since around June of last year. It works great, but I must caution anyone thinking of doing this to be VERY careful. Experience with soldering and a steady hand is a must. One could fairly easily mess up their phone attempting to do this.
Could you do this with a powermat if you wanted to? I have a few laying around I could use.

What I originally meant was pictures. But now that you've added them and I've seen the glory, this mod is really quite impressive and I'm thrilled you shared it with us. But now that I think about it, could this also do USB wirelessly? That would be pretty amazing.

No, the transmission of data wirelessly is achieved through modulated EM waves. This is simple inductance: a changing electric field creates a magnetic field, a changing magnetic field generates an electric field, so a current carrying loop placed near another loop of wire will induce current in the other loop. The receiver in the phone is engineered to "create" the "proper" amount current to charge your battery when combined with the base. In theory yes, but not with this equipment.
How does the phone treat a USB cable being plugged in - will it charge ok, and have your data transfer rates been adversely effected? I wouldn't think so, since you're only touching the power...

I have used the USB charger and data transfer cables without any problems at all. Also I have copied some files off of my phone to my PC since the "upgrade" and did not notice any extended times or anything that would remotely make me think something was wrong.
I did not run a speed test before and after to see if anything slowed down, but as you said we are only touching the power pins, so I highly doubt anything has changed.
Has anyone found the wireless charging accessories for this guy yet?
it's supposed to use the new wireless charging 'standard' so any pad with the same technology should work
e.g. from amazon, type in qi charger
http://www.amazon.com/Energizer-Qi-Enabled-Position-Inductive-Charger/dp/B0041RRORA/ref=pd_cp_e_1
Verizon sells the Wireless Charging Battery Cover.
I tried to paste the link but the Forum won't let me (not till after 8 posts anyways)...
Looks like the back cover is out of stock on Verizonwireless.com. Does anyone know or have heard of this cover working with a Palm Pre Touchstone? Thanks...
Well I got my wireless charging pad and back cover today. The back cover is twice as thick as the stock cover. I came from a Palm Pre so I have a bunch of touchstones. Unforunately, I can confirm that the revo wireless charing system is NOT compatible with the touchstone. The verizon charging pad seems to sense when the phone is near and turns on. The touchstone did not, so that is probably one of the problems. I measured the voltage from the back of the touchstone cover and it wasaround 5.1 Volts. I am hoping I can use the touchstone coil on the stock cover of my revo and wire the charging leads to the revo. The revo has 4 pins for charging but the touchstone only has two, so I need to find out how to wire this. i may have to go through the USB 5V connection. I love my touchstone car mount and I am really hoping to be able to use the touchstones for charging the Revo.

Also, gsxrpilot would you say the wireless charging it worth it? for the almost 100 bucks you spend on it? and does gsxrpilot mean you ride a gsxr street bike?
Well there is a deal this month where you get the back free with the pad, so $70 for both. I got a little more discount because I complained that the only reason I needed a new phone and wireless charger is because my Palm Pre stopped working. I would say that it is worth the convenience. Constantly plugging in the micro usb charger due to the low battery life gets old. Now if I can get my touchstones to work, it will really be worth it.
And yes I have a '92 GSXR-750 and love to fly RC Planes and Helis, hence gsxrpilot.

I might have to get that then. Also, that's sick. My neighbor has a 20xx dsxr 750. They are a blast to ride.
Couple of gripes about this...
I bought the Wireless charging back for my Revo and it's not compatible with the Powermat that I already have, apparently the "qi" technology works differently than the induction that the Powermat uses. It IS compatible with the Energizer power mat which uses the same "qi" technology. but you're looking at the same price for either charging base.
Secondly, the wireless charging cover is twice as thick as the stock cover so any skins or cases you want to get for the phone will not fit. My silicon cover almost fits but buldges out on the sides.
I still think wireless charging is the way to go, just a heads up for those of you who are looking into this.
Well I got my touchstone to work with my Revo! I scraped the charging coil from the back of a palm pre cover (bought 2 for less than $5), then hot glued it on the back of my stock revo cover. I had to dremel 4 holes where the metal disks were and added 2 disks per hole since the revo is heavier than the pre and more disks help it stay on the touchstone better. I now have 4 little bumps on the back of my cover. I searched everywhere for the connector that would fit in the stock cover but couldn't find it. So I wound up using magnet wire and soldering directly to the charging tabs on the coil and the top of the connectors on the phone. Didn't have to use too much solder so I could remove the wires if I wanted to go back to the verizon charger. It is nice having the stock cover back, the verizon wireless cover was so much thicker.

Any way you could post a picture? I'm interested to see if that setup would work for my powermat.
OK,I think I attached the picture correctly. I did the following:
1. Remove the charging sticker and assembly from the back of the Palm Pre charging cover. Do not use the Pixi charging cover assembly, there is a ribbon in it that cannot be re-assembled after removal.
2. I took my dremel tool and routed some space off the inside back of the cover. The revolution cover is a bit thicker than the pre cover and I was concerned it might be too thick to allow the inductive power through.
3. I also routed some indentations in the back of the cover. (see Phone Back Image) I'm not sure if this was necessary either but I had really hoped I could mount the phone vertically on the touchstone in my car like the pre so i put a second set of metal disks behind the indentations. As it turned out, the revo is much heavier than the pre so this didn't work.
4. I glued the sticker and assembly to the back of the stock cover. First I tried crazy glue which didn't work that well so I wound up using hot glue.
5. Finally I soldered magnet wire from the palm charging tabs to the wireless charging tabs. Top tab to the top charging post (there are 4 of these posts, I only used two) and bottom to bottom. The top tab and post is ground, the bottom tab and post are +5V. (see Phone Inside 2 image)
6. I snapped the cover on (there is still a small gap which I haven't quite worked out yet but it works ok). Stick it on the touchstone and it says "wireless Charging" (which is actually annoying and I thought I had figured a way to remove this notification but it came back)
Now all of my touchstones work for charging and I am not sure I will ever go back to the verizon wireless charger.

awesome stuff, I will definitely give this a shot and post results.

nice hack.....looks like your method could work on most any accessory case
how long would it take to charge the revo?
Charging probably takes slightly longer than through the USB port. The phone can get a little warm too but I have never had a problem. It's really convenient in the car where I glued the touchstone to my center console. If you have ever tried to drive while plugging in the tiny usb cable you will know what I am speaking about.
After a bit of searching I made a dock for my Nexus S and thought I'd show the results here.
I found out about polymer clay in this post (the thanks button is disabled for some reason...).
And I used the resistor values listed here, as some other threads showed they also worked with the Nexus S: Fun with resistors (home/car dock mode + more)
I ordered a Sparkfun microUSB breakout board, bought some resistors at a local electronics shop and four blocks of black Fimo clay at a nearby arts shop. I had the other supplies on hand:
-Soldering iron, solder, etc.
-Shrink wrap in various sizes.
-Hot glue.
-Aluminium plate.
-USB cable.
-Narrow and slightly rounded file.
-Box cutter or exacto knife.
I made the cable first (and did not take pictures at that time) and ensured that part worked before tackling the clay portion of the project.
I soldered one end of the resistor on the breakout board and the other directly on a stripped portion of the ground cable. The data wires remain functional as I am using a wall charger that properly shorts the D+ and D- wires to enable AC mode. I secured everything to the board with hot glue and finished off with shrink wrap.
This was my first time working with Fimo and it went well. I wrapped my phone in cellophane for a test fit along with the modified cable. The cable however isn't rated for the baking temperature so this was only temporary.
After baking, it turned out that I had misplaced the portion meant to hold the cable, so I snapped it off and made another with some left-over clay. The cured material can handle rebaking with no issues.
A bit of rework on the attachment point with a knife, test fit again, glue the board and file a notch for the buttons.
The phone slides in and out smoothly. I'm quite satisfied with the results.
Update: dock still works great. I've made one mod though: I took an old mouse pad, tore off the cloth on the top, cut a shape matching the dock's bottom, and hot glued the two together. This anti-skid pad means I can turn off the alarm or answer a call (which the phone answers in speakerphone mode right away) without inadvertently moving my phone on the nightstand.
Goodbye,
Darkshado
Wow really cool, and might have to try it.
Sent from my Nexus S 4G
nice work! I still have mine intact and it suffered some serious banging. Love your design too! Cheers.
a video of the process would be awesome for us noobs
Thanks for the feedback!
daudster: sorry, but its too late for a video. The good news is that there are plenty of good soldering tutorials out there.
This post by Fallon also has nice pictures that are very close to what I've done myself.
I started with the cable.
My "donor" USB cable was a standard compliant color coded affair. (Red Vcc, Black Ground, Green D+, White D-)
Checking with a multimeter to be safe is a very good idea.
Given the gauge of your typical USB cable wires and the breakout board's holes I suggest you presolder your wires.
Holding the stripped end of your wires with a sufficiently massive pair of pliers will make a nice heat sink to prevent melting the insulation when soldering.
Instead of doing like Fallon and placing the resistor above the breakout board, I soldered one pin on the board, the other on a stripped section of the ground cable "downhill" from the board. If you want to do it like this, make sure that you don't short your resistor with the ground cable. Then cover with shrink wrap.
Lousy ASCII art diagram below:
(Breakout board on the left)
ID--------R------\
GND--======---====
Depending on your exact design, this may not be necessary, but I opted to secure the small gauge wires to the board with hot glue, prior to covering with a larger diameter length of shrink wrap. While this cable's solidity might not be commercial grade, tugging on the cable by mistake would not risk as much damage.
Also a departure from Fallon's post is that I am using a Samsung OEM wall charger that shorts the Data wires in the charger itself, enabling AC mode, so no need to do it on the breakout board. My cable is confirmed working on the computer with both ADB and USB Mass Storage file transfer.
Test as you go to make sure none of your solders introduced unwanted short-circuits. (Fail to do this is and you could very well KILL your precious Nexus S or computer.)
Now, the Fimo part.
This was my first time ever working with Fimo and it turned out to be easy. As you work the material you heat it a little (friction) and it becomes a bit tacky to the touch so I worked on a small sheet of aluminium foil, wax paper might be better yet.
The aluminium plate is used for curing, as its much easier to handle with oven mitts and solid enough for this purpose.
Roll three blocks of Fimo in a sheet about 6-8 mm (¼") thick. With a blade, cut the excess on each side to end up with a properly sized rectangle for the back and bottom of the dock. These leftover bits will serve to support the back as well as the breakout board.
I kept my back flat, you may want to have it curved like the Samsung OEM one. Your choice, I chose flat because its easier to make and to simplify reuse with minimal modification when I'll change phones down the road.
The notch in the bottom for the buttons may be done before or after curing. Before, your fingers, a pen, coffee stirrer sticks or popsicle sticks all work. After, a rounded file or sandpaper.
My first breakout board support was misaligned so I had to break it off. For this reason I suggest you consider doing it in a second curing. This way your test fits are going to be much more accurate.
Most cables aren't rated for high enough temperatures to follow the Fimo in the oven for its curing. That's what lead me to making a support with a notch and using hot glue to finish the job. It's also flexible enough in case your alignment isn't perfect.
Goodbye,
Darkshado
Realy nice work
a quick sanding and molding would of gone miles to make it look normal!
i think that i'm going to try this!
thanks:good:
Hi!
First, I'm sorry for English, I'm not professional.
A few days ago I made a working wireless charger for Motorola Droid 4.
What are the benefits?
People says, the original inductive charging cover is not compatible with most of cases.
Who live away from USA, can't use a wireless charger, becouse it is only available (officially) in the US. It is very hard to find on eBay or any other site. Almost impossible.
Very cheap. The original charging cover at US, Verzion is $29.99. (+ shipping, and need a person who ship it to me) It is only a cover, and we still need a charger as well.
So, I found a charging pad with and without receivers. There was a small problem. The receivers are only for Samsung Galaxy S3, S4 and Note. Their connectors aren't compatible with Droid 4, but the charging voltage is OK.
We need to take it to compatible with Droid 4. I looking for a long time, which one can I choose. Fortunately I made the right decision.
I bought that: Qi Inductive Wireless Charging Upgrade Kit for Samsung Galaxy S3
Link here
That is only for $30.10 with EU plug. The package include charging pad, usb cable, 1500mAh charger and S3 compatible receiver, and worldwide free shipping.
The size of receiver unit is compatible with free space of phone. We need some cutting but it isn't horrible.
First, I recommend you try, how fits the module in your phone.
Then mark with a felt.
The electrical connector pins are big, (and incompatible) we need to remove it carefully. I used a rework station with hot air (360°C) but you can use a medium sized soldering iron. I think, about 50-60W of power is enough. It took for about 30 secs per pin.
It is important, you need to place the receiver in such a manner, if you remove the back cover, the S3 and some other text need to be visible! Otherwise it will not work!
You see backside of the phone, and the camera is on top. Removed cover. In the right side, you can see four copper pins. The top row is irrelevant. We need tha bottom row. In the bottom row, on the left tere is the +5 V pin. On the right, there is a Ground pin.
We need to make contact between +5V pin of the phone and the +5V charging pin of the receiver unit.
Place the receiver unit to the phone, and see what size of copper wire you need. The lower pin of receiver unit is the +5V. We need to connect it.
I used a wire,1 mm in diameter. It is lacquered, I cycled down it from an electrical part (coil).
I think, that half millimeter in diameter is enough, but a found that, and it is recommended due to the relative high current (about 1A).
When you use thinner wire, you can easier take the cover to the phone.
So you need to solder wire to receiver's +5V pin. Please use the minimum quantity of soldering wire, becouse if you make a big knot there, you will have not enough place to take cover back.
When it is done, you can see how can you bend (or cut) the wire for best connectivity with phone's 5V pin.
Now you need to solder a wire to ground, like the previovus one, but not sure, that the two wore have enough space, and we can make easily short corcuit.
For this reason, we will use the iron cover of the SD card slot. This is a very good ground point.
So, one cable will go down, other is go up. They can fit and the soldering is more easy.
PLEASE BE CAREFUL! I recommend, before you make any electrical or hot operating you need to put an aluminium foil or an iron plate to top of the battery. I think to taking out battery and then in, is not easily possible, becouse after soldering there are the receiver. The battery can damage and explosive! The plastic parts of pohone can tolerate the heat for sort time! If you can not solder succesfuly, you need to wait while the parts cooling down! I recommend, use flux and/or high quality of soldering tin. Take out the SD Card! Please don't make short circuit!
It is not too difficult, but you need to be careful and attentive.
When the soldering done, you can try the charger.
Before you can take cover to phone, you need to cut the lower center of receiver. (you can see on the cover, exactly where. There are a claw and on the phone there ara a hole) Important! We need all of holes on phone, so the wires must not hang in to holes.
I cut the piece of receiver unit from lower left side, at the speaker.
Thats all. We are done. I think it longer to read than make :cyclops:
I made some pictures, I will mark these and upload in short time.
I'm going to measure the charging time with:
1,5A USB charger (direct cable)
1,5A USB charger with wireless charging pad
1,5A USB charger with wireless charging pad (phone in a 1 mm thickness of Trident case)
0,5A standard laptop USB (direct cable)
0,5A standard laptop USB with wireless charging pad
0,5A standard laptop USB with wireless charging pad (phone in a 1 mm thickness of Trident case)
I use that from 3 days ago. It works correctly. By the factory, the charging current is 1000mA with the 1,5A charger. About 66% of efficiency.
The USB charger's stand by consumption is 0,4W.
When the charging pad is connected and it is in stand by mode, the consumption is 0,98W
I'm going to bring images, and refresh the post, but here (Hungary, GMT +1) the time is am 2:31.
Good luck guys!

That great way to charge the phone. i know that my usb plugin is getting a little wore out.......glad to know that there another way to charge up the phone in case of emergency. Congrats.
Hi,
thanks, it works for me
My IQ receiver was a bit higher, or the battery, so I had troubles to fit it in. My solution was to cut every superfluous piece and pull the uper layer of slide away. Additionally, I put it a bit nearer to the camera, The last thing was to horizontally cut the gold contacts and solder the wire directly on them.
During charging, the usb charger+pad+droid 4 use 7W, without the droid 4 the pad+charger draw 0,4W, both measured at the primary side ot the charger.
Best regards,
mifritscher
Thanks for the info, looks promising I love your using Micro SD casing as GND
BTW the pad + receiver can be found at eBay for as low as US $12 Gonna try out for myself soon.
Did you get to measure the charge times?

Charging times are about equivalent
Different approach, same result
Hi, thanx 4 the great idea.
I took a different approach to install the charging pad. I felt not comfortable to solder directly to the phone, so I used copper-tape, capton-tape and some short wires I took from old headphones to mod the pad directly into the back cover of my phone. it got a little bit bumpier (half a mm), but it charges perfectly.
I applied some solder to the ends which connect to the pins, so the copper wont oxidize and the connection has more pressure.

That's a nice solution, and pretty much how the "real thing" was probably set up. I noticed that the back has an internal indentation where the pins are to accommodate the connector, and I had experimented with how I might fit a charging pad in there (actually, it was the connectors that I saw as the biggest challenge), but didn't manage to get anything that I thought was robust enough (I was using cut down parts of a SIM card for the pins to make contact with - you look to have done a better job with the copper tape.
I'm really surprised that we can't buy a new back with all of this gubbins already installed - perhaps you should manufacture a few?
mugen 3800mAh inductive charging cover required!!!
i'm tempted to try this myself. the droid4 keeps getting better.
i just experimented with cardboard, seems to have plenty of room between the cover and the battery. i definitely need inductive charging.

Hi! I copied your method for wireless charging but I was too lazy for soldering. That is why I used only copper tape. I ordered under 5$ charging pad and receiver for Galaxy S3 (cheap from China) and it is working good. My receiver says that it can output only 0.8A so I guess it is little bit slow. Can you tell your feelings about the heat? I think that my Droid 4 is pretty hot but I never used wireless charging on other phones so I don't know if it is normal. But thanks anyway posting your method :good:
Here is pictures. I tried to take picture about the bump. It is not bad but you can feel it.
A short warning in advance: What I did here could have gone horribly wrong (considering my soldering skills). I am not responsible for any broken devices that occur because of users following these steps. Oh - and please excuse the ****ty image quality. Since I could not use my good phone camera I had to use my not that good tablet-camera for the images.
I got my ZeroLemon battery and I thought: "Why should it not be possible to use NFC when I have the battery attached to my phone?". A short time later I got:
-NFC Sticker for G4 from Amazon
-Some solder
-A soldering iron
-Two short cables
What I did:
First solder the two cables on the NFC-contact-poinst of my G4 and on the other end on the NFC sticker. And guess what - it works. I did not even have a problem putting the case back on. So now I can enjoy NFC and a huge battery (and I am pretty bad at soldering so I bet you guys can do this easily). I also made a short video showing that reading a NFC sticker and using Android Beam works:
What I did (more details):
Take off the back cover of the G4
Test run (no soldering yet but hard to get working)
Get two short wires
Use duct tape (or your fingers) to hold them in place on the two lower contact pins on the right side next to the battery-tray
Hold (or duct tape) the other ends of the cables to the NFC sticker (lower pin to lower golden contact point on the sticker, higher pin to higher golden contact point)
Wake up the phone and place NFC tag on the sticker
If if works you can start soldering because it will work too (if you are careful and don't break anything)
If it doesn't work make sure the cables are really touching the contact points on the phone AND the sticker (and that they each touch only one contact point on every side) and try again
If it still doesn't work try a) a different cable b) a different NFC Sticker
The real deal:
take out the battery
(optional: make sure the cables are straight and not bent. Will make working easier)
CAREFULLY solder one cable end on the lowest contact point on the phone
CAREFULLY solder the second cable on the contact point above
CAREFULLY solder the first cable to the lower contact point on the sticker
CAREFULLY solder the second cable to the upper contact point on the sticker
Put battery in and test
Tipps for getting the cables bent right and put the case over the phone:
hold your finger onto the soldered contact points on the phone (as soon as they are cooled down a little bit) and try to bend the cables so that they run on the side of the phone (be very careful here because the nfc contact points can break)
Insert ZeroLemon Battery
CAREFULLY bend the cables on top of the battery and place NFC Sticker there
CAREFULLY put the ZeroLemon Case over the phone and battery
Test

Neat. It's a shame zerolemon didn't come up with a sollution. My g4 came with two backs so I could use the sticker from one right?

Of course (if you manage to get the NFC sticker off without breaking it). I originally bought the spare one because of qi-charging but did not wire up those cables (I do not plan to wirelessly charge this battery because it would take forever)
