how to "batterie low cannot program" solution - Motorola Droid 4

a little solution to save money and time
take a droid 3 batterie and ad it too your droid 4 like in the picture

After a while of trying to solder to the micro b tiny contacts to make a cable, I ended up doing the same thing as you. Then came here to share, to find your post haha.
Except I attached mine to a usb cable to a usb charger, just put a piece of thick paper to not short on anything and tighten the screws down with the wire under the washers:

[HARDWARE] Dinc Seamless Wireless Charger stock battery (NO USB STICKING OUT)

>>>>>><<<<<< PDF With All Steps And Images Added For Your Viewing/Downloading Pleasure >>>>>><<<<<<
***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).
(Images can be seen in: Wireless Charger.7z)
Here is a video of the end product and how it works:

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.

OTG cable angled "correct" for the N7

I thought I saw a thread about this a long time ago but search as I might I can't find it again. Anyway, I was wondering if anyone had a link to an OTG cable that angles...well...down if the N7 is in landscape mode with the camera on the left side? I've ordered 3 and they all angle up which really doesn't work well in a case or anything since the "hinged" side is generally on the left.
Hopefully this makes sense. LOL
Alternatively, does anyone have a link where you can buy the male MicroUSB connector? I've tried Amazon, Monoprice, and even Radio Shack (that's desperate) and can't seem to locate this part.
Thanks!
here is the one i have.. You must also get a micro a usb to a usb female adapter.. Not sure i ordered from the same company but i know it was over seas.. i bough them as a set one up angle one down angle..
that is term.. down angle micro a usb cable... Be careful that you do not end up with a usb mini which is a b type connector..
micro a down . look close at the picture so the flat part of the connector port is to the top . which is the back side of the plug. ok that all sounds confusing but . well here is the link..
http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_kw=down+angle+micro+usb+cable
One more thing.. Make sure its a 5 pin if its not usb. just slit the wire carefully and cross pin 4 and 5 will turn it into otg. Or use a otg connector at the end... This is what i did.I pluged my otg connector into this.. and its stil flat to the back of device..

I don't think the down angle would work. Basically, when plugged in, I want it to angle to the left side of the device. It seems most angle to the right. Then I could actually put the cable and flash drive inside the case and out of the way so it would be more "permanent" when I'm out and about.
I'm all for angled cables, but the down angle one doesn't excite me. I was much happier with this style cable:
http://www.ebay.com/itm/Left-angled...=US_Video_Cables_Adapters&hash=item23243a6e6a
This isn't an OTG cable, but I use this in my car so the cable is tucked away neater. I had the same confusion when trying to figure out if I needed left or right. I ended up buying both because my phone is one way and the Nexus 7 is the other, so I knew that was a win/win. Prior to realizing that I just hit up Google image search and looked for a larger picture of each one... then tried to envision how it would plug in accordingly.
Hmmm. Mine faces "down" when the camera is on the right side. The smart case folded behind from the top.
I got mine from Amazon for my Galaxy Nexus a while ago.
Those listed above from eBay are wrong. Those would actually attach front to back (screen to back housing) and would be awkward IMO.
Mine attaches and the cable slides down the lining of the trim. I got it from Amazon.
Here is what you want. Take note of the micro USB port:

[GUIDE] DIY smallest Micro USB OTG to USB Adapter

Update: v.2! (half a penny)
Inspired by this video/OTG, pass to 0:47. Which I couldn't find one to purchase. This L design when plugged in is a bit smaller than a penny. No welding needed! Use (female USB for game controllers, mouse, ect). Designed with a case-on in mind.
======
You'll need 3 parts for hardware. Micro USB OTG, Micro SD reader, ofcourse Micro SD card and a software of your choice to run it. I don't root so I'm using Nexus Media Importer.
Be safe and wear gloves. You don't want to get hurt for this mod.
======
Step1: Cut in the middle of the left or right side of Micro USB OTG. Be careful, use glove on the hand to hold it down. (note: the OTG link that i provided is the exact one that I used to mod, but you can find the cheapest parts from Amazon or Ebay, ect.).
Step2: Peel out the inner part of the OTG.
Step3: Cut the part closer to the Micro USB completely off (with wires still intact). Carefully peel the wires to the far end of the USB female. Then cut the rest of the plastic off like in the picture.
Step4: Turn the Micro USB end to make a L shape like in the picture. I used glue gun to clued it together. You can use electrical tape if you like. Enjoy!
**I'm not holding reliable for any injuries or broken parts from this mod, do it at your own risk**
This is the original size of the device when it's plugged in, it's about 3 size of a penny in length.
Step1-3
aaaa
Step4
====================================================================================
Version 2 still retained female USB for mouse and game controller or a case in mind.
==========
You'll required soldering, glue gun or electrical tape. (note: this version is a challenge to make. If you think you can solder the wires into the small spaces on micro USB's bins then proceed or you can make version 1 which required no soldering)
==========
Step1: Strip micro USB and female USB completely. (any spare female USB from old devices will do. Make sure you have the right micro USB end like in the diagram if you decided to get a spare)
Step2: Measure the wires as needed from micro USB to female USB. Then pre-cut the outer layer of the wires so you can bend at 90 degree angle with ease when wiring the wire along the sides. (careful don't cut the wires inside). Next, strip a few millimeter from both ends of the 4 wires.
Step3: I suggest to lay the 4 wires on top; along the micro USB and solder it in the pins. (though I didn't realized this obstruction was a big deal until it resulted in a bump on my model when wiring it downward). Curve your stripped end of the wires for easy soldering. A trick I used to solder the wires to micro USB is putting a thin foil paper in between 2 pins. After you're done, remove it and repeat until you're done.
Step4: Lay your micro USB on top of the solder point of the female USB at 90 degree to shape the L. (make sure no metal part of the micro USB touches the female USB sholdering point. You can lay it on top of the female USB but it will add a few millimeter thickness). Follow the diagram to solder all wires to the female USB.
Step3
aaaa
v.2 when plugged in it's half a size of a penny. You're seeing USB plugged into the OTG with microSD inside.
**Credit to redgreenlaser for diagrams**
Thanks for the "how-to", Capt.PP.
Thank you, with your suggestion, and pictures, I can also put the USB behind the tablet as a U, and maybe make it smaller without the USB (male and female) only the card reader
I like it!

Cool, Aleemz, how did you make yours?
If you want to make it smaller and you are going to the trouble of handsoldering and hot glueing, you can just get the Micro USB Plug
http://www.digikey.com/scripts/dksearch/dksus.dll?vendor=0&keywords=609-4051
Remove the USB shield, solder the Plug Directly to the USB traces, and Hot glue around it, you can reduce the size by half (maybe even more)

I think that, if I were to make one of these, I would make it in a "T" shape after removing the male and female USB connection, with the opening for the micro sd card facing in whatever direction seems best, so long as the card and its holder are parralel to the side of the device that the micro USB port is on. That way the whole thing would stick out no more than 5/16th's to 3/8th's of an inch when plugged in to the micro USB port and the protruding top cross part of the "T", that being the part with the micro sd card, would act as a grip for removing the device from the port.
(If that makes sense.)

You also have to look at cost effective here. The parts that was used only cost $1 for OTG, 30 cents for small USB, minus the Micro SD card. Though i'm not recommending 30 cents for small USB (they didn't clued it and harder to get the Micro SD card out) compared to the one above I recommend in the link.
The L design flushed with the screen surface and thinner compared to the bottom surface or a device as a whole. It prevented from accidentally snag the OTG when swyping on the screen. It's very easy to plug or unplug since you have a penny side in width (when you DIY you can add grips) and 2 penny side in length if you have a big thumb.
The T design, if i understand you correctly, you want to stick out above the screen a bit so you have grips to pull it out? I can ensure you the L shape have no problem of unplugging. Though you eliminated the female/male USB but it still lay hidden on the edge bottom of your device. Instead of buying new parts (may cost more) you can use the OTG I recommended to strip out all the white plastic to make it even smaller as you want to reduce in length when laying on the edge bottom. Cheer.

I am going to just try soldering/wiring a micro-usb jack directly to a 32GB flash chip from a torn apart flash drive. Still waiting for parts to come in the mail. Here is a pretty good wiring guide that should help anyone looking to do the same.

You could probably do the same thing with a micro-sd hard adapter.
Also another idea : Build it directly into a case, much like this Galaxy Nexus Battery Case

Tutorial on how to make dock for Sony Xperia ZR and other Xperias at home (DIY)

Things needed,
(1) Any hard plastic sheet to make charging base stand (I had used plastic from square plastic bottle, image attached)
(2) Nokia to sony erricson - old mobiles' charging adapter. (image attached)
(3) Ordinary USB cable with power surge protection (not a must thing to have power surge protection).
(4) Two sided sticking tape. (image attached)
(5) Scissors and sharp blade to cut the plastic sheet.
(6) Soldering iron.
(7) Original sony charger - the one which came with your mobile.
(8) Quick fix to stick the things together.
First of all, you have to make charging case to adapt the phone, measure the width of the phone, add 2 mm to it, draw square (black square as in figure) with this width and height on the plastic sheet from which you intend to make case. Now measure thickness of your phone, add 2 mm to it, draw two parallel lines (blue lines as in figure) on the adjoining rectangular lines on the square, secondly draw another two parallel lines (red lines as in figure) parallel to blue lines to make supporting sleeve. Fold them according to shown in figure, and stick them with quick fix to hold them in place. Allow it to dry.
Then put your phone in this case, mark the placements of golden contact ports (dock ports) on the side wall of the case with pen.
Take the charger adapter, adjust the contact pins according to distance between golden contact points of phone, cut the space on the side wall of the plastic case to fit this charger adapter so that after fixing it, the contact pins of adapter comes in contact with phone golden contact ports.
Now, cut the second end of USB cable (the end towards the power surge protector), find out which one is +ve and which one is -ve, and solder them to the pins of charger adapter after opening the covering of the adapter (non branded adapters are easy to open) so that +ve PIN COMES IN CONTACT TO THE UPPER GOLDEN CONTACT POINT OF THE PHONE, second one is ground, so solder it to the remaining contact pin. Close the cover of charger adapter, remove adjoining plastic insertions pins up to the base, fix adapter with quick fix to the already cut out space of the side wall of the plastic case and allow it to dry.
Plug this USB to your original charger and the DOCK IS READY
You can stick the case to wall with two sided tape as shown in photo, so that when phone is placed in the case, it remains tilted and hence by gravity, golden dock port comes in contact with charger adapter pins.
Hope this tutorial will help you.
----Inspired from XDA-----
Disclaimer:- I have and am using this self made dock to charge my own Sony Xperia ZR without any problem to phone or battery but I do not take any responsibility of what so ever happens to your phone by making and using this charging dock.
Charging speed?
I tried to make a dock using a printer usb cable and it worked but the charging speed was really slow. I got 1% charge in about 20 mins.
Could you please tell the charging speed using your dock?
Thanks.

100 % charging required 3 hrs in my case vs 2.5 hrs with direct charging. I suggest you to use the USB cable which came with any mobile device for charging/data transfer. They have very low resistance value. You can also check the power output of native charger and your dock if there is any difference.
Thanks very much for this great tutorial,
But one thing i didn't get is how to adjust the contact pins to the right distance ?

For that, all you have to do is, open sony charger adapter, remove the pins and replace according to the distance required (distance between golden dock points of phone). There are grooves already present to adjust the space between this two pins in majority of after market charger adapters.
That's my DIY Dock for ZR
That's my DIY Dock for ZR
Hi!
I have the honor to present my version of DIY dock for ZR. ^^
I made it in ​​1 afternoon. It cost me 0€. (I've collected the 2 pins and the micro USB port on a broken phone that I had in a drawer.)
It's made of wood as you can see. I designed it for my ZR fits perfectly in with the silicone case. But I also intended that the 2 contacts are adjustable so that I can use the phone in the dock without case.
My ZR really fits perfectly, I just have to let go in the dock and it sets up all alone and recharge.
The 2 little pieces of steel works as 2 little springs and permit that the contact of the pins with the phone is always perfect. And the 2 screws permit to adjust exactly the position of the 2 pins.
I will soon paint the dock. But it's not urgent.
The only drawback is that the dock charging speed is not as fast as usb cable charge speed. But It's not a problem of design of my dock.
So there is some photos of my dock.

I made it in ​​1 afternoon. It cost me 0€. (I've collected the 2 pins and the micro USB port on a broken phone that I had in a drawer.)
It's made of wood as you can see. I designed it for my ZR fits perfectly in with the silicone case. But I also intended that the 2 contacts are adjustable so that I can use the phone in the dock without case.
My ZR really fits perfectly, I just have to let go in the dock and it sets up all alone and recharge.
The 2 little pieces of steel works as 2 little springs and permit that the contact of the pins with the phone is always perfect. And the 2 screws permit to adjust exactly the position of the 2 pins.
I will soon paint the dock. But it's not urgent.
The only drawback is that the dock charging speed is not as fast as usb cable charge speed. But It's not a problem of design of my dock.
So there is so photos of my dock.

Looks cool man. This is genius and creativity.
Xperia ZR dock-charger plates polarity??
Hello everyone!
Can anyone tell me the polarity of the Xperia ZR's charging plates? I mean which one is positive and which one is negative?
I want to make my own dock as well but I am afraid that I might fry my phone by messing up with the polarity. I don't have a tester by the way.
Can anyone show me a picture of this?
Something that looks like the attached picture below.
Please do *NOTE that the picture is only to tell you what I mean. It doesn't mean that the content(polarity) is accurate.
Someone please correct the illustration if it's wrong. If it is right, please confirm as well.
Thank you guys!!!

Hi
The polarity on the picture is good. The + on the top and the - below.
The first time I hadn't any idea about the good polarity, i've try by putting wires in the plates, it was the good polarity at the firt try. But wanted to try the invert polarity (idiot idea ), the result, ZR shutdown instantly ! I was very scared but it restarted, fortunately.
Don't forget to show us your DIY dock when you will have finish it.
Kodus buddy!

I will post some pictures of my own D.I.Y. dock when it's done
How about the charging speed of yours? Is it fast enough? Others in this thread had experienced very slow charging speed. I wonder what caused it. Perhaps, the type of wire they used. So I guess I need to look for good wires suitable for fast charging as well. Any suggestion?

Concerning charging speed, it's a boring problem for me.
At the beggining, my ZR charge well but slowly. If I go to bed and connect the ZR at the dock with less than 20%, the tomorow morning, the ZR wasn't completly charged ( around 90%) after 6-7 hours.
And since a moment, my ZR don't want to charge. I put it on the dock, the led light up but it don't charge, it's discharge ! Or sometimes it charge about 1% per 30 minutes, so currently I let my dock in the drawer... :crying:
I don't know from where comes the problem. I've exactly the same electric values as a friend's official Z dock (4,86V and 1650mA for me) but the ZR don't charge. My electric circuit is good as well. Electric contacts seem good.

That sounds strange. Are you using the original charger unit that came with your phone? How about charging via micro usb directly to the phone, does it still work?
I really think that there must be a specific type of wire that should be used for fast charging.
Also, try to double check the in wires of your dock. There could be short circuit happening inside or maybe the wire itself is nearly, completely cut.

Yes I use the official wall charger (EP880) designed for the ZR. With USB cable + wall charger my ZR charge fastly.
Concerning wires, it's not needed to use some specific ones. You just need to have the correct electric values at the dock pins. In my case it's good, I've the same power as on an official dock. You need to have same values as you measure with the wall charger, it's approximatly 5V and 1500mA. In my case I've 4,86V and 1650mA with the official wall charger and with my DIY dock.
There is no short circuit because I've the good values in the pins. Due to the conception of my dock I can check the electric values by return my dock when my ZR is in place into it. And all seems good... in theory ! x)
EDIT : I use CM11 Official. I think my problem is a software problem and not an material problem. Mabye with old nightlies dock charging works but with new nightlies there is a bug.
thanks for the tutorial! I'm planning to make one!
Hi !
I have solved my problem of dock !
It's really weird but it was a problem of weldings not properly done. However, the current seems to pass but not charge.
Now I have +1% by 2 minutes of charge.
so this is mine.. made from audio cassette case, old siemens phone data cable and a lot of hot glue.. ^_^;
just until the cheap dock from ebay arrives..
Dude. The aftermarket dock is better than stock and costs 10 bucks on ebay shipping included. Buy that. Best tutorial.

Hi, here's my version of a diy dock
Things needed,
1. Styrofoam /thermocol block
2. Kekda charger (that's what it's called in Mumbai)/ universal battery charger
3. USB cable
4. Sharp knife
5. Screw driver with a 4inch + shaft.
6. Heat.
Get hold of a Styrofoam /thermocol block cut to desired shape so as to fit your ZR and outer body. A 1 inch thickness on all walls is recommended.
Take the universal battery charger and remove the battery holder part having springness in it.
Take the screw driver and heat it and then cave in a slot for the Kekda charger in the back of the Styrofoam block by slowly melting ( Styrofoam shrinks in the presence of heat), else use a heated solder gun to cave in a slot.
Cut one end of USB to expose wires and solder on the Kekda charger part.
Red wire + on top of the charging pin and black - on lower.
After soldering press in the Kekda charger and adjust the pins accordingly.
Done.

Guys save me....
Look i need help........i accidentally put the wrong polarity of the cable to wrong plate on the phone ....i had around 80% battery that time.Now the phone wont start . I tried taking out and putting back the battery but it still wont start......Expecting a reply ASAP :crying:

DIY Wireless charger for Droid4

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.
Update 2016
@zuloo.de
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.
