Is there a fix for the USB (no)charge bug??
Are you using an xda1 usb cable?
I'm using the BoxWave miniSync, it says "xda" on it, but BoxWave who sold it to me as an adaptor for the XDA II say it's the same, they also sent me the following email today:
"We are aware of the issue, and it is not a problem with the miniSync as you
may suspect. The O2/XDA II has a software bug the prevents charging from
low current sources, such as USB. If you have a unit that has the
attribute, you should contact HTC or the brand which your XDA II is made by
and request the bug fix.
The problem does not exist in every XDA II, which is why HTC did not make a
public announcement regarding the bug. We have done in-house testing to
confirm this, as our wiring structure is identical to the stock connection,
with the only difference being the incoming power current levels."
I've got one's, wried as :
+5v -> pin22
UDC+ -> pin 14
UDC- -> pin 15
GND -> pin 18
it can sync on XDA II, but can't charge when battery less than ~60% from USB port (more battery is ok).
Do I have to change GND to another pin to force my XDA II charge?

I have tried the usb charging on 2 pc's. On the first one it started charging very slowly then basically stopped charging as I used the device.
On the second machine it charged very well regardless of whether i was using it or not. I was also activesyncing on the second machine.
I bought the Pocket PC Tech's Lil Syn, which is very similar to the BoxWave product, and the USB sync/charger drained my battery.
I read BowWaves response that only some MDA2 or XDA II have a problem with this, but what I find interesting is that I can charge via USB on the cradle regardless of how low my battery is, but I seem to have issue with the Lil Sync product.
Why would this be? Is the cradle more powerful than the PPC Tech or Boxwave products? That does not seem likely.
It seems if the cradle does charge, but these other products do not, then the problem would not lie with the PPC Phone-2003.
USB Sync & Charge cable.
Okay.. I was a little Pissed when my cable wasn't working, so I started looking into the differences and found that ground was going to Pin2 on my sync and charge cable, where my stand alone charger didn't have that. So I snipped the wire that went to pin 2 and walla, it charges now.
I still am having problems getting my battery pack to work. It's a pack that takes 4 AA's and is supposed to charge it too. It supplies more Volts than the USB, but it won't start the charging process. I'm going to try and wire it more simpler to my USB Sync/Charge cable and see what happens.
Let me know if this helps,

as ive replied saying on other posts......
XDA 2 charger kicks out 2Amp max XDA only does 1amp max
most charging assesories are XDA 1 compatible only yet people say they work on the xda 2 means they have found out they plug in simple but they dont kick out more then 1amp as usb ports can only handle 1amp max.
thats why it doesnt charge it might charge if you turn your device off and disbale activesync from waking the device up but it will take twice aslong to fuilly charge maybee longer but if the device is awake youll find that the device is using up more power then the usb charger can give out so in otherwords your device will die instead of charging itself up.
gaz
I have a standard xda1 sync/charge cable and it charges my xda2 regardless of the amount of charge left in the battery, and it does it very quickly too, I think it is a bug in some of the xda2 machines.

Hi: can you provide your pin configuration for continuous charging while idle or being used.
I have this adapter that came with my xda2, is the wiring correct for use in a car adapter charging? Thanks.

do you have a pin config for your second m/c. Thanks.
Further to my earlier post, my xda2 now no longer charges from the usb sync/charge when the xda2 is low on battery, this only happened since I got my first "low battery" warning, I put it on charge, looked a few minutes later and it had gone from 10% to 7% battery power.
Hi all, pls look at this post... the non-charge issue can be addressed... http://forum.xda-developers.com/viewtopic.php?t=5438
Best regards,
Hi guys,
my beloved qtek 9100 is having some weird behavior since last week: i let my battery drain to 9% and then recharged. The phone would not recharge it, showing a red led. After lurking and learning about this problem on those devices I made a "starter" with three 1.5v batteries and gave the battery the necessary tension to start recharge cycle.
I thought that would be the solution but no: the phone kept stopping recharging at 25% or, the next time, at 75% with no apparent reason. Then, i tried many solutions like directly charging the battery with a cut usb cable, with the stock charger, with powered on phone, powered off phone, etc. No clue.
What leaves me shocked is that the battery, even when at 75%, drops suddenly to 0% after enabling the radio module thus killing the device...
An important note: same behavior with two different batteries...
I'm going nuts...
Problem still unsolved. Today i left the device recharge at 100% (took about 3 hours), detached it and tried a rom downgrade. Obviously it died at 50% of rom upgrade procedure. Sweet...now it's almost bricked, bootloader screen and recovery procedure to be done
What could it be, an hardware failure?
Hi there, same problem here: I have the phone with two batteries, on half a year old, one brand new. The batteries DO charge on another phone, but after a regular charge is gone, my phone never gecharges the batteries. It might be the charger circuit? If not HW, is there any chnce to do some SW stuff?
Unfortunately this thing s just a brock now ...
Bye

It's good to find someone with my very same problem...although i've got no solution, still!
Is there someone out there who knows how much would cost a fix and if it's an hw issue or not? Would it be possible to fix it via DIY?
Thanks in advance
Someone suggested me to test the current output on the main contacts to see if the device is actually supplying power to the battery.
So i plugged the wall-charger on the device, took a multimeter, checked the output: the device is supplying 3.5-3-7 volts. So, i suppose it is correctly charging. Why, then, after a turn-off / turn-on the charge level drops after showing as completed?
Could it be a sw problem, then?
USB voltage is 5v. If you are not getting 5v on the USB plug coming from that charger, then that is probably your problem. Have you tried using a USB cable to plug it into your PC to charge?

Thanks for the hint
I suppose the problem is another...in fact those 4 volts are coming from the battery itself. Pluggin in or out the power plug doesn't make any difference.
I tried taking out the battery and there's no power coming through the main contacts of the phone. Is this the right way to check or should i use some different method?
Thanks again
Last question: is there someone who could show me where the recharge circuit should be on the mainboard? Have you got any information about the ease of a diy repair and about the price / availability of the spare part?
Thanks in advance

Are you using the wall charger or with the PC. Cus you will get more power input from the Wall. As so i dont know the reg key off hand but if you change one thing you can make it so your phone does not charge off the PC. Maybe you have found a new one!

With both the wall charger and the pc usb plug. Checked the registry key and no way, it's ok.
It's really incredible, the total charge cycle takes a couple of hours, like if it were charging regularly, but after unplugging it goes down. It is like if the "carge counter" or similar records the charging, with the battery actually not receiving power.
did you solve your problem yet?

hi there.
shortly-i have this phone with no orig. usb cable and with no wall charger. it was friend of mine phone actualy. given to me with dead battery (i am not sure but i have trouwn it away long time ago)
first I did was to wait until friends of mine from china had sent to me 2 batteries compitable with the phone. what i discovered is that a normal ordinar usb cable cant charge the phone's battery it only can connect to the pc.
second what i did is this: i found my old charger from a very old panasonic cell phone and had a try to make the charging process with the simply contacting corresponding pinouts of the battery to the +&- of this same charger (somehow i dissasembled the plug of that charger and it became more "comfortable" to get in touch to the pinouts of the specific cingular's battery)
that unordinar way i did discovered that i can charge these batteries even not sure how much appropriate that other brand wall charger is. It seems its pretty much the same as a power characteristics.
Meanwhile (as i dont use this phone) i had some free time to search the net and to have better idea about that strange unordinar power charging matter with that model of a phone. The situation is that i cant find a place nearby me to buy a cheap usb and wall charger and become using this nice device finaly.
And also i dont want to buy these cable things before clearly understand why this happens ..
I did try also to charge this phone with a HTC brand wall charger but no sucsess again cause it seems this wall charger is for other htc phone (even same mini usb plug and same characteristics)
What i need is to have answers by someone very informed about that matter and let me know what exactly is the specific power charging matter (need explanations i mean) with this phone. If sharing some good ideas about how to remake others usb cable or wall charger for geting it work along for me in such a case , i will appreciate this very much
thanks
charge
hi ! please forgive me for my bad english! in this case you can charge your phone in 1 way! you need to procure a motorola or any charger with same socket but attention the charger must have 6 volts and no less than 500 mAh(milli amps)! you cut the wires and one wire put on the + of the battery you will see the signs on the battery an one wire at the - no matter which one. and you need stay with the wires 3 - 4 minutes on the battery ! then you put the battery on the phone it will start and then you cand fully charge it with the usb cable ! good luckk ! i hope my inf will help you!
no
no it doesnt work that way.
what i need is the simple answer : what is so special into the pinouts of htc cingular 8125 wall charger?
thats what i need only. Then I might figure out how to proceed
Thanks anyway
I don't know if anyone else has had trouble doing what I have done, but I've got the Cingular 8125 (HTC Wizard 100), which is also known as the HTC 8125.
1. I bought a car charger at a convenience store for $6 that had the mini-USB plug. It worked like a charm. Never any problem there.
2. I also bought a standard USB to mini-USB cable from the local computer store, because I had lost mine, and it also worked fine for both synchronization and for charging.
3. I bought a second wall charger, buying a standard mini-USB wall charger sold pretty much everywhere cellular phone chargers are sold. It's a common charging port, and this generic worked for me as well.
I'd be interested to hear if anyone has had problems with these types of devices not properly charging the unit.
Even my USB cable for my portable USB hard drive will power my unit.
EDIT: About your problem with it not charging. I had that problem about a year ago, when my battery got extremely old. It wouldn't charge even with the original charger. I just needed a new battery. The batteries get old and stop taking a charge after a certain amount of use. How long this takes depends on how heavily the batteries are used. They, like car batteries, do not last forever.
I had this problem when I had my wiz too. The battery died and drained, and my phone refused to charge it. I took it to an AT&T service center, and they had no clue what the problem was, and they wanted to issue me a replacement (it was a G4, I had a G3, I wasn't about to fiddle with that at the time.) So I asked to borrow a demo device they had there to fix it. I charged my battery on their demo device no problem, got it up to 3%, and finished charging it through my USB cable in the car socket.
It appears to be a sort of one-in-every-few-or-so type condition, but I got hit with it.
seems like noone can tell me if something special inside the mini-USB plug.
i realy cant charge. Very nice device, but i cant make it charging up whit cables.
guys, from up there, say that nothing special about the charging cables, but i trust what i see not what i read.
Perhaps there is a problem with your USB port on the device? USB charging has standards, and all devices that need power from a USB port have the same power pin configuration. Otherwise, they can't call it a USB connection. It would have to be called a proprietary connection, and they would have to change the plug size/dimensions and pins.
If there isn't a problem with your battery (which is the most likely source of your problem), then it may be a loose connection on your USB connector. This happens with a number of devices.
If a sync cable connects to the PC but will not charge the battery, then you definitely have an unusual pin detachment of some sort, or a bad battery.
thanks again..
for pity i was writing a lot to make my recent post and finaly it desapeared cause my session was left.. its funny in some case, but now i just dont want to repeat all what was intended to be posted
i give only the link where you might see why i was assuming that this is a kind of a special matter here with that htc 8125 charging
//pinouts.ru/CellularPhones-A-N/razrv3_charger_pinout.shtml
so, any more help will be appreciated a lot
thanks

Hi - Too bad for the OP that asked questions but did not listen to this brilliant post.
I have confirmed that a variation of this method works perfectly! I have an old Cingular 8125 that I have been trying to charge for over a year using various USB chargers and NONE would charge the device.
The reason that this may happen is that the original charger has an output of 1 full amp which is much higher than most chargers. The voltage is the same but you need a charger that can handle such a strong current draw.
Nearly all USB chargers can only handle around 250milliamps - 500milliamps which is about half the power needed to breathe life into a fully discharged battery.
The best solution is to NEVER let the battery fully discharge.
Here are the details of what I did:
1. Find the best match charger of 5-6 DC Volts and ability to put out as close to one amp (1000mA) as possible. I chose an old Sanyo SCP-07ADT that is rated at DC 5.4V at 800mA. The plug can be any type, no need to be USB.
2. Cut the connector off the end of the cable and strip the outer black part up about an inch and then strip the positive and negative (red / black respectively) wires up about a millimeter, just enough to have bare metal ends to touch to a small area.
3. Take your battery out of the phone, look at the back of battery for the + and - marks which correlate to one of the metal connection points on your battery, this is where you will "touch" or "attach" the bare ends of the wires.
4. Plug the charger in making sure not to short your bare leads. Before you do this double check that the OUTPUT of your charger is indeed DC voltage so that you don't hurt yourself. You do not want AC output and it can be dangerous.
Then touch the bare end of the red wire to positive of battery, and black wire to negative terminal of your battery. I held them with my fingers while surfing the web for about five or ten minutes. I had no idea if anything was happening or not but it "felt" like the battery might have gotten just a bit warmer.
5. Unplug the home-made bare wire charger and put battery in your phone. Quickly attach a USB charger or just plug into a USB cable of your computer. I pushed it in and nothing happened at first but finally I heard the standard "bleep" when you plug a USB device in. I knew that I made progress because it never beeped before it took about 30 seconds and several "bleeps" of connecting/disconnecting from USB but eventually the charge light stayed on!
It's been about 30 minutes and I'm up to about 50% charge and been using the phone heavily while charging.
So, in summary... never let your battery discharge below 5% or you can only charge it with an OEM cable rated at 1amp (rare). IF you let it discharge to "dead" then charge for 5-10 minutes with the "wire" method and then charge normally!
Thanks to Dozzen for the original idea!!
Wizard that won't charge
When my Wizard/HTC 8125 goes dead my cure for the battery is to use a 9 volt charger with the wires stripped back also. But, my method is a bit different. I place a standard Christmas Tree light bulb (the newer small ones)in series with the charger wires. Observe the correct polarity. The battery is labeled + and - so that part is easy. By using the small light bulb you are doing 2 things. 1.You can see the slight glow from the bulb and know that proper connection is made. 2. You are limiting the charging current to the battery.
If you get really creative like I did you can solder a couple of small nails or in my case a set of red and black probes to the setup and the points on these nails/probes make for much easier connections. Note.... This method may take a few minutes longer but, is much easier on the battery.
In my experience once the battery is below a certain level NO charger that I plug in will work. I just purchased a used 8125 from eBay and brought it back to life most successfully with this method.
hy there my htc wizard battery whos dead so i charched with a cable with + and - the phone starts but when i try to connect to a usb or a adaptor it doesnt charge anymore it show me the charge icon on the baterry but it doesnt charge the usb works fine it's sync to my pc but it doesnt charge anymore... what sould i do?
So it seems no one touched on what really matters here.
A design flaw, in my opinion. The HTC Wizard cannot recharge via USB unless there is enough power to turn on. The reason is because it requires the OS to charge.
So, what many people already posted are very creative ways to charge your 8125. The easiest and cheapest way, in my opinion, is to use AA batteries.
1) Take two AA batteries and tape together so they are in series. Imagine it like this... [- AA battery #1 +][- AA battery #2 +]
2) Use two wires and tape one to each side of the AA's (one on the + side and another on the other battery's - side since the - of the first battery is connected to the + of the second).
--w-i-r-e--[- AA battery #1 +][- AA battery #2 +]--w-i-r-e--
3) Connect the positive (+) wire to the positive (+) side of the phone. By this I mean the 6 metal pieces that stick out to contact the phone battery. I did it by wrapping the wire around the top most one (or second top most, it's been over a year since I've done this.).
4) Connect the negative (-) wire to the negative (-) side of the phone. Again, bottom most or second bottom most (see #3).
5) Insert phone battery while the wires are still in and connected to the two AAs.
6) Let the power flow for 30 seconds or so and then try turning your phone on. This part is the important part because you cannot use a USB to mini-USB connected to your computer to charge the phone unless the operating system can function. Meaning, it needs to be turned on first.
7) Once the phone is on, plug in the mini-USB part and connect it to a computer. I'd recommend getting at least 5% battery before disconnecting the AAs, seeing as you need to be able to start up your phone long enough for the OS to boot. Once the OS boots, you can fully charge it through a normal USB to mini-USB connection on any computer.
old post but just wanted to say thanks. Used the wire to battery method and got phone turned on after 2 mins of holding wires to battery.
Long story, but I bought a used Fascinate without the stock charger.
Could someone install, or hopefully already have, the "Battery monitor Widget". Then plug their Fascinate into the stock AC charger or stock car charger (NOT the USB on a PC), and let me know what the usage (ma) reading is on the widget.
More of the story. Basically, I know that at least on older HTC devices they would pull more charge/operating power from a non-USB connection. Actual USB is limited to 500ma load, so they had a system that kept the current low on USB and bumped it up for non-USB. All of the non-stock cables that I have show a very low charge rate on the Fascinate. It in fact runs the battery dead while on charge and I use the phone with GPS software.
i can tell you the factory charger is putting out 5v at .7a(700ma).

Thanks, it is good to know that they stick with 5V. But it just means that it can put out up to 700ma. I suspect it is using about half of that.
If you can cut open the wires and insert and ammeter in series, that is what I need to know.
edit: nvm ...
Found it. I have been searching for this for a couple of weeks and just now stumbled on the right search keywords.
For anyone that wants to know.
The Fascinate appears to pull about 350ma from the 5 volt supply normally. But, if you short out the USB D+ and D- lines in the charge connector, the charge current goes up to about 600ma.
That will help me not have a dead battery when using the GPS.
Oh, as an added bonus, you don't get the USB / Debug notification.
Hi everyone;
I've having an interesting time with my nexus 7 (2012 wifi 32gb).
Before I left on vacation I couldn't get the thing to charge. Looking at the usb port I thought it had become to damaged to make a good connection. So while I was away I ordered a new port assembly. Installed that and still no charging.
Oh the battery cell voltage had gone down to 2.2V so it's in a sleep mode. No problem used a proper lion charger to trickle charge it back to life then further to about 3.8V.
At that point it boots up though the optimization took the charge down to 2% so couldn't do more testing but clearly it worked just fine. However the thing won't charge. Plugging it in to USB it does detect the connection but does not draw any current (as shown by a usb voltage/current monitor). It will show the charge screen, go through 3 cycles of the battery filling animation then shut off.
I check and the voltage is getting from the usb cable into the connector. I traced the ribbon cable from the IO board up to the motherboard and at the other end I also get a nice 5V reading. Clearly the connection from the USB to the device is being made no problem.
At this point I am thinking that maybe I blew the charging circuit. When I was orignally trying to get it to charge before leaving I was applying all kinds of stress to the connector to get it to charge and there was a few times where I think I shorted it (usb monitor showed >3A and the device reset).
Anybody have another theory?
At this point I can't really use it as charging the cell externally is dangerous and not convenient. At this point from what I have seen with my testing and on here if I want to use it I would have to apply 5V to the battery connector (sans battery) which I haven't tried yet.
