Hello to all fellow i9305 owners
Can anyone out there confirm that any of the existing wireless charging mods on I9305 lte actually works?
The reason for my asking is that the my usb charging socket started to show signs of wear and tear . Basically my phones socket became very sensitive to any standard micro usb charging cable. Sometimes it works but 50% of times it doesnt. (I have tried four different cables)
The only cable that works 100% is the MHL one (HDMI-out with USB-charge) which is slightly longer and goes in deeper into the socket (making better connection). Since I've realized the issue was with the mechanical failure of the usb port I decided to explore the wireless charging methods.
There is a big thread about it (which is locked due to people misbehaving) so please do not post links to mods (I've read them all).
I even took the plunge and I have bought all the gear for palm mod (that didnt work) and the gear for QI mod (that did not work either).
Im beginning to think that either my fone is faulty (but no way of proving it since there is no official Samsung wireless charging yet) or perhaps there is something I need to do with software (custom ROM?).I am on latest rooted stock rom by Lyriquid, BTW
Any help is appreciated.
Thanks

You do not need any mods you buy the wireless charging back cover and matt for a few £ on eBay or amazon

Thanks for the reply
Unfortunately I have tried that (perhaps I shouldnt have used the word 'mod')
Have you actually got a working wireless charging 'thingy' on GT-I9305?

Yes: My GT-I9305 is enhanced using the charging coil, etc., out of a Palm Pixi Touchstone back cover with a Palm Touchstone puck. I used copper tape and resoldered the contact points on the wireless charging coil so that they align with the contacts in the phone. The coil is stuck inside the unmodified original back cover using the white sticky cover from inside the Pixi, and some white duct tape to cover the copper tape extensions out to the contacts. I have reused the metal disks with the sticky coil cover to locate the back on the charging puck.
It charges at about 230 mA through my TPU back cover, slower than normal, but perfectly adequate.
The Touchstone puck is fussy about cables and USB PSUs.

Well, Thank you very much
Your post was very helpful and informative, especially the bit about the 'fussy puck'.
I will try that setup again but with different USB cables and chargers perhaps.
Im guessing there isnt any led confirming that the puck is on ?
Thanks again (thanks button pressed too)
Hi guys,
I've used the palm wireless charger with one of those stickers that you attach to the phone on top of battery. It was working perfect but you have to put the phone with this sticker exactly on the middle of the charger otherwise won't work. If you have a case on the phone won't work either. It takes to much time until it charges the battery (I've had a 4500ma ). You can check if the wireless pad works with a multimeter. Put the sticker on it and check if it gets any electricity. :thumbup:

Yes, now I know I need a sticker. Also as I realised I needed the sticker I thougjt I might put magnets as well too.
Then I tried this all and it was wouldn't work with my flip cover so I've attached the palm sticker to the bak of my flip-over case and put the original backing away.
Now its all brilliant . I have my phone in my case and charging wirelessly with no issues.
Those usb sockets arent really made to last, arent they
Thanks everyone who helped.

if you want a "pre-manufactured" wireless charging solution, you can also go on ebay and buy the Qi wireless receiver pad. it fits underneath the battery door as well and NFC still works. The only thing I don't like about it is that it causes a small "dome" on the battery cover so if you use a case, the more "sturdy" ones like the otterbox or the ballistic or anything that will hold its shape to overcome the slight bump.
apart from that if you're handy w/ modding and such, the palm touchstone mod is also perfect since it's insanely cheaper than anything that is offered out there.

Are you still long for wireless charger?
I have current stocks.
You can check out my Facebook page
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.

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.

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!

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.
perhaps

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:
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.
Hello guys,
Few weeks ago i read about connecting standard wireless qi usb adapter to phone itself. I mean, connect 2 stripes of cables to 5v and ground on motherboard, so usb would be still avaiable. Do you know where on motherboard those pins are ?

Interesting, I'm trying to find out too. I did a mod that way with my NOTE1. Mostly likely near the USB port, but I afraid it'll affect the NFC , because NFC is on the Cover. And the coil 's pcb must be extremely thin.
I would gladly get rid off nfc anyway, as I don't use it. Voltometer is on its way to me, so any time soon I'll try to update the thread
news pliz??
thanks..
Can wireless charging be used when case is still on the phone?

current Qi is good for 7mm i believe...which is plenty of space for most cases. it wont pass through metal though, and I'm sure some materials hinder that more than others. I used a couple different cases on my nexus 5 and was able to charge with all of them.
The Qi chargers are 12V I believe. I modified a car charger to fit the adapter for the Qi wire. I had to solder it to the 12V wires in the car plug. The 5V would not charge it.
You should be able to find 12V power coming out of the power supply.
Hi,
I love the idea of wireless charging, especially with a waterproof phone so you don't need flaps or something like that for the charging port.
Ok, well the charging port of the xperia phones is very nice and I was using a dock quite a long time.
But hey, lets try charging the phone via qi.
This is the case thei the receiver mounted:
Since I decided modding the phone itself is not possible until larger modifications are made I decided modding a case to become a charging case.
The dock-ports are ideal for this.
So I bought a QI reciever. The reciever for the Samsung galaxy note II would do the job because the polarity matches with the polarity of the dock port (the upper one on the phone is the positive terminal).
The first receiver I bought was mechanically perfect because it is very small and thin. I taped it to a QI charger and connected the pins via lab wires to the phone. Unfortunately the receiver starts pulsing its output. I think the phone draws more current than the receiver could handle. Watching the receivers output with a scope showd that the receiver has much ripple and the voltage is around 7 V. This is to much, luckily the phone took no damage.
Here is a photo of the bad one:
So I bought a second receiver.
I'm from germany so, this is a link to german amazon.
You have to remove the 2 gold pins and replace them with 2 spring contacts.
I was using these contacts:
Put the receiver in the case, put in the phone and align it, so the spring contacts can touch the dock connector.
The remove the phone, fix the receiver with some tape and use a 2 component epoxy the fix the part with the spring contacts at its correct position.
Oh, and cut a hole for the flashlight led of the phone.
I used J-B-Kwik.
I uses the glue also at the outside to provice stability:
the case is just a bit to small for phone and receiver but it holds the phone nicely.
I forgot my qi charge at the office so I cannot provice a image with the phone charging, I can take a picture tomorrow.
Yes, the performance would be better if the receiver is mounted below the plastic case between plastic and leather. But is is to big for that. Even cutten the edged is not enough.
Here is a comparison with the old, non working receiver, it is smaller and I cut the edged.
I works well enough.
Hopefully this would be usefull for somebody.
I you have any questions, don't hesitate to ask.
