where can i get usb charging port part for my defy MB525 Green lens which has a small cable which connects to a IC its quite different from mb526 usb charging port :cyclops:
Might be able to find spare parts somewhere

I am trying to charge an O2 XDA IIi device with a sync/charge cable, but it seems to discharge the battery instead of charging it. I have tried with different devices, different cables and different batteries, but the same thing happens every time. Am I doing something wrong, or is there something I do not know about?
maybe USB CABLE or PDA's Connector 13－15pin have some wrong.
it happens only when connected to cable or also when cradled?
There is a possibility that the connector on the device itself has bad contacts either on the pins inside the socket or the pins which are soldered to the device's PCB inside the device (you cannot see them from the outside if the device is not disassembled).
What are the specifications of the official HTC chargers ?
I mean not the voltage/amp, but the way the phone identifies that it is its genuine charger and it can draw max power (ie. up to 1A).
Since normally with a real dumb charger via usb it should not draw more than 100mA (or maybe 500mA but even that would not be USB specification compliant without a proper USB negociation).
I guess this is something like 2 pins shorted on the charger cable ? (or some phones use a specific resistance between 2 plugs as identification)
If I want to charge at max current with a usb car charger, what can I do (short pins) ? And what will be the max current it will try to draw ?
The charger and usb cable provided with my Magic both have standard shaped mini usb plug. Though my collegue's HTC Dream came with HTC shaped mini usb plug. Is there any difference exept in the shape of the plug ?
Current drain
Hi
I have charged my sapphire with a power statin and it indicates about 800 mA of maximum current drain.
I made the charging wire myself from a broken charger so i think you can use any car charger.
The htc shaped mini usb is only to indicate it has charging wires and audio wires.

Yes you should ba able to, I'm using a Blackberry charge for mine.

My defy+ cable has on the mirco side two metal pins on each side. Normale cables got only two metal pins on the wider side of the mirco side.
Do you follow me? I made picture below had to use * because spaces will disapere when posting

Sorry, I don't understand you, but you can use standard microusb wires for data and charge with your Defy+ (I usually use a Samsung usb wire)
The cables i used on my htc Desire wont charge or are only use full for date transfer. When i trie to charge true my charger or car charger. It start charging and within a second i got a message that it is unconnectend and then connected again. And it loops.

Those aren't "pins" in the sense of providing data signals or charging current. They are more like small springs designed to improve the mechanical retention of the micro USB plug in the socket. They don't make any difference to the electrical or electronic function of the USB cable, beyond reducing the risk of a poor physical connection, or a loss of physical connection if the handset is moved which charging/transferring data.
My Blackberry charger's micro USB plug doesn't have them , but the short USB to micro USB cable which came with my noise-cancelling headphones does - and the only function of that cable is to charge the battery in the headphones. I think you will find that there are a number of subtle mechanical variations of this kind between micro USB plugs from different manufacturers.

I used with my Defy+ usb chargers and usb cables from Samsung Wave and Blackberry 8990 and all of these works property for charging and for data transfers.
Maybe your HTC usb cable don´t work propertly?

Other possibilities are that the charger is faulty or providing a charge current which is slightly outside spec, or that there is a problem with the battery. I have seen problems caused by both of these kinds of fault (with third-party chargers and batteries) when using my Motorola USB cable.
I'm trying to make a fast charging cable for use in the car. The current charger I use seems to work fine, but the coiled cable annoys me. When I use a standard USB cable the charging reverts to slow mode which means the GPS and screen drain the battery faster than the cable can charge it.
The charging cable that works has a resistor between ground and the unused pin 4, but what I want to know, is this the only USB charging standard that the Droid4 supports, for example does it support the one where you put a resistor between the two data pins, or the one where you just join the data pins together?
If it supports either of those, then this project just got a lot easier as I can just chop the Type A connector off my USB cable and do all the work without having to solder a Micro USB connector.
Could you de-solder the coiled cord and solder in a micro USB cord or even a female USB cord for removal of OEM usb... or is that what you mean in the last paragraph... If you want I could give it a try as I have three rapid car chargers and several USB cables...

I'm not sure if this has anything to do with your question but try an ipad or tablet charger (2.1 Amp) which i use on my droid 4 and charges it fast.
Regular chargers use 0.7 to 1.0 Amp. I know tablet chargers are bulky but they tend to charge your device faster.
Also maybe this thread will work for you: http://forum.xda-developers.com/showthread.php?t=1984838
I'm using a 2amp car charger with a USB socket at the moment and I assure you it isn't charging at that speed. The other charger with the coiled cord does charge at the higher speed, but it also has the odd wiring.
That thread is interesting, is exactly the kind of thing I was talking about, but I'm looking for confirmation that it will actually work with the Droid 4 before I start hacking up cables. The Droid 4 seems to be fussy about which chargers it will work with, my 2amp charger worked fine with the HTC Desire Z, for example.
Another part of my reason for doing this is I want to use the right-angled USB plug that is on my USB lead, but that Micro USB connector is sealed and unmodifiable.

I'm not sure but there is a radio called ihome ic50 (Google it) i own it and it has a special switch which the manual says if the device has a proprietary charging protocol flip the switch. I made a quick test and it charges in both ways. I'm pretty sure your idea will work as long you know what you are doing. BTW the ihome ic50 is pretty cool for any android device.
So I've ended up destroying (the charging circuit) my I9000 by removing the usb connector the wrong way. I've followed this guide
but I was to impatient with heating up the usb connector., Because of that the copper pads came along with the pins of the usb connector.
So now my question. Is it still possible to make the charging circuit work?
I've found these two images. Source 1 and Source 2. I don't know if the images are right, can anybody confirm this?
But if I run wires from the pins of the usb connector to the components in the image would it make the charging system work again?
Or are there any other smart solutions to fix this issue?
