Hi
I am looking for a way to charge HD2 without need to allways plug usb cable to mobile.
Inductive charging would be great, but we are not that far, but HD2 has power connector under his back cover, it is there for charging with car kit. Possible solution would be to use back cover with charging connectors and appropriate charging base. So I would just have to lay my phone on charging base without any connectors.
Is something like that on market?
Thanks
Martin
nope..........
There is in fact such a thing, but i do not know if it would work with the HD2.
I have seen something of that nature at cebit or something, really cant remember which computer convention it was, but it has been reviewed in various mag's
hxxp://www.berryreview.com/2009/10/30/gadget-of-the-week-powermat-wireless-charging-pad/
(change hxxp to http)
I have seen an inductive charging pad system at Carpone Warehouse in UK.
Technically, i suppose it would be reasonably simple for a company like Powermat, or other inductive charging manufacturers to make a replacement battery cover for the HD2 that ties into the contacts on the back of the phone, which were originally going to be used with the car holder, before it got redesigned, and allow recharging of the battery.
Well... Inductive charging... Would be nice.. But:
There must be a coil build in in the back cover and some regulator hardware. That is making the back cover thicker. This might be no problem if they do it right.
An other posible problem is the induction itsef. It is close to the electronics of your phone. What will happen with the signals and even can it damige the electronics?
I would like to have it, but only when it is tested and no risk of dameging the phone and disturbing the signals.
Well Powermat make back covers for iPhone, Blackberry, Nintendo DS so it can't be doing that much damage
has anyone seen a power mat backplate yet ?
I believe from the CET and CeBIT 2009 and 2010 technology was shown for the integration of current wireless charging in mobile phones. I believe HTC has added a second charging connection just below the battery, behind the battery cover. Perhaps a flat coid can be placed at the back of the current cover. The coil can be connected to the secondary charging connection. It was previously inteded by HTC to be used with a special battery cover that connected to the first concept model of the HTC HD2 carkit.
I believe Duracell or another battery company demoed a wirless charging system that could be integrated with current mobile phones. Maybe it is a start to look there?
Even if it worked for hd2 it would charge the battery at very very slow rates (typically @ less than 80ma)
I never have my phone charging through usb...only into my pc when im copying files or flashing Roms
I just got a spare Battery & Desktop Charger, as i work 12hour shifts (listening to music) it comes handy having a spare battery
As long as inductive charging is in it´s childhood-state it´s another waste of valuable energy.
Not for the single phone or person but taken together the ever increasing billions of users it´s a massive waste of resources.
Did You know that the worldwide use of internet (PCs, Notebooks, Netbooks, Phones, Servers, transmission lines, amp-nodes etc.) consume already more energy than worldwide car-traffic ? Should make You think ...............
Hello,
Two quick notes: The Palm Pre battery cover coil has its terminals on the correct side and very close to the charging terminals in the chassis of the HD2, given the amount of room in the chassis. Unfortunately, it looks like the EVO has a larger battery cover, and from the pictures I doubt that the coil assembly would fit length-wise under the HD2 cover. I'm not sure if there are electronics in the "tail" of the assembly, but if that could be removed I think it would be easy enough to find terminal block that would fit in the indent of the HD2. If you look at the Palm assembly you can see the bulge for the coil, the four bulges for the stabilizing magnets (?) and the terminal, I can't see what would be in the tail besides maybe a diode.
Unfortunately, though, the cover of the HD2 is made of metal, which I think would cut down further the efficiency of the inductive coupling of the coils, maybe critically so. If they're using 1A 5V supplies for the base, it might push the supplied charging amperage low enough that it wouldn't be useful. So I think that until someone fabricates a plastic cover, adapting the Palm Touchstone might be difficult.
I do have to disagree that the use of the principles of induction is anything but mature; these inductive charging systems are basically loosely coupled one-to-one transformers, if I'm not mistaken. Engineers made excellent use of inductive coupling a long time ago, if nothing else those tube amps that some folks like so much sure did.
Regards
Any idea what the order is for the contacts below the battery?
I have my palm pixi cover and touchstone. I plan to remove the cover and attach everything to a hard plastic back cover. I just need to connect it to the right terminals.

Unfortunately I have yet to find the pin-outs for these contacts. Please share them if you find the information.
You might get some information from this hack created by Derek Hughes. It looks like he has had a similar idea to yourself. Unfortunately he does not use the hidden contacts under the battery cover, instead he just re-routed the micro usb port, kinda messy and a bit impractical.
This hack was carried by many of the phone and tech blogs. But the links below are from Hackaday.

Good luck.
Can we combine or close this in favor of this one?

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

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.

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.

Someone please correct the illustration if it's wrong. If it is right, please confirm as well.

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.

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.

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

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.
I was looking for a solution to this problem and after opening the nook I found out that on the socket one of the contacts is pushed towards inside - I've strighten it and tried to insert the cable but the cable pushed the contact again. So I glued it with some epoxy glue and currently I'm waiting until it cures.

It turns out that it wasn't the main problem - the nook now is working on power from the charger but it isn't charging the battery. My next try is to solder on a cheap lion charging board from china inside. I couldn't find any 5v test point but there is space for a capacitor near the connector and on the battery connector there are batt+ and batt- test points. This should be enough for the charger.
edit:
Its working!!
i've used a cheap lion charging module from china for 1$. I've cut out the microusb connector, wrapped it in duct tape and fitted it inside the nook.
It's slower than the original charger - only 1A but its working
Hi dkuku,
Thanks for the post.
Could you tell me where the orange USB wire goes?
TIA
