my wizard battery won't charge.
i have tried another battery and another rom with no change.
wehn i plug in the sync cord, the izard reognizes that it is on external power but just won't charge the battery.
any ideas.
thanks
...try to find out, by measuring, if the ±5Volt DC is present on the pins on the inside of the ppc which is needed to charge the battery. Probably your charging circuit is busted and the ppc should brought back for repairs...
thanks for the response
what is ppc
where do i measure the voltage.
when i first connect the sync cable, it starts to charge for one or two seconds and then stops and reverts to a normal non charging screen.
thanks
PPC stands for Pocket PC
What you speak of, I had the same problem on my wizard.
My battery finally died and I couldnt re-vive my phone.
I bought a new battery off of ebay, put it in, plugged it into the charger that came with my phone, let it charge overnight and I havent had a charging problem yet.
My advice, as well as alot of others on this board, dont use any other charger other than the one that the phone came with. I know I wont be.
...inside your ppc,when you remove your battery, you'll see different connection pins which are normally connected to the battery. With power attached (and without battery) you measure between 2 pins at a time. WATCH OUT for shortcircuiting, be careful!!!. You can use an analog or digital voltagemeter. I don't know which pins, so you have to try it yourself.
You should measure ±5 Volt DC which's delivered by your adapter. If there's no power then your charging circuit is defect and you'll have to let it repair...
reading about a volt on the internal pins that connect to the battery.
so it's the charging circuit.
damn
I had the same problem twice with 2 different batteries. it seems if the batterie dies completely, the device can not recharge itself. something like a car, you need to have enough juice to start the car so you can recharge the battery.
I took 2 paper clips that i used to connect the charger directly to the battery( bypassing the phone). you need to be careful with that, make sure you connect the right battery pins. I left my battery like this for 15min, just enough to have aniough power to start the phone and continue the charging process regularly.
As mlarif said the battery can fail to charge if totally discharged. So if you are not absolutely certain your circuit is faulty there are at least two threads here describing how to butcher a usb cable to jump start the battery.
Sorry I can't remember the colours of the wires off the top of my head. But a search may find the relavent posts.
...you can also use a 9 VDC battery to give the ppc batteries a boost for a few seconds. But indeed be sure to use the right pins
(btw did you measure any VDC on the batteries..?)
I recently left my Cingular 8125 in Bootloader mode over night, connected to my PC not knowing that it couldn't charge while in that mode. I woke up, and couldn't turn it on; I eventually found out that the battery couldn't charge while in Bootloader mode.
The only solutions that I've seen posted are to: (A) Get another charged battery, (B) Charge your battery in a working Wizard
Both solutions aren't possible for me at the moment... what I needed to know is if there is a way to charge using some funky wiring rig using standard AA batteries to power it for about 7-10min. or so.
Cut one end off an old usb cable. Then plug the usb cable into your computers usb port and touch the black wire to the (-) on the batt and the red wire to the (+) on the battery. It takes a few minutes, but the battery will charge. Then put the battery back in the phone and boot into the os. Then charge the phone as usual.

You can jump some wires to your battery from a battery charger to get some power to your battery --- need 5.7 volts -- positive to positve, negative to negative but I would not recommend doing this. Your battery is a lithium Ion which takes a special charge. Take it to a Cingular Store and ask the clerk if they could just charge it up in another phone for a couple of hours. I'm sure they won't mind.
Lithium Ion batteries are fussy about how they are charged, so its best to do it in another phone or a charger made for your battery.
Cheers!
Thank you guys sooooooooooo much for the info.
You have no idea how important this is.
EDIT: I stripped the USB cable, the outer wire is silver and there is quite a bit of it... there are four wires encased in the middle: one black, one brown, one red, one orange... I do not know which wires to connect to the pads on the battery.
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
SOLVED: HTC Wizard (Cingular 8125) Dead Battery Wont Charge

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.
Equipment
Xbox 360
Sony Ericssoon W995 , data cable. (i think their all the same)
Method
I cut and then revelaed the 4 wire's used in the data cable. I removed all unnecessary bits from the cable leaving just the red and just the black cable.
I revealed a bit more of the cable inside the red and black cable by taking off the outer coat. then connected the + and - up from the wire's (red and black) to the + and - on the phone. put my battery in the slot which holds the cable nicely.. Plug in the USB cable to the xbox 360
Before i tried this i wasnt quite shore if this would work. but it seems to be going well and has a pretty fast charging time. Fully charge my phone in a hour, not sure how long the official charging method takes
........................................................................................................
Ok, why did i do this? .. Basically I left my data cable for the X10 in college and its the weekend and bank holiday monday. which means i have to wait till tuesday before getting it back.
Am i causing damge to the battery or phone? I am keeping a close eye not to over charge my battery, i always take it off when it hits 100
If I understand it correctly you are now charging your battery directly with 5 volt from the Xbox USB.
And without any control over it?
This is in my opinion not a wise thing to do. You are overcharging your battery, and a LiPo battery can explode rather nicely from what I have read.
I've You somehow connect the 5 volt to the correct pins in the microusb connector of your phone, the the electronics in the phone are overseeing the charging process.
I would never do, what you are doing now.
Attention do this at our own risk as it may damage our phone.
My used samsung galaxy pocket-neo was becoming impossible to charge causing me to break the adapter cables with constant wiggling and balancing acts to get it to work. I took it apart and the micro usb socket looked like an extremely difficult soldering job to replace.
The solution I am using for more than a month with no adverse effects is to cut the plug off and strip the 2 power wires at one end of an old usb cable. There are 4 different coloured wires, red, black, green and white. The green and white wires transmit data, whilst the red and black are the power lines. Red is positive, Black is negative. The sleeve of the cable has a metal mesh which is not necessary for my purposes so I electrical taped it back onto the cable.
The next step is to remove the battery of the phone: I have only done this on phones with removeable batteries. The ones I have used have three terminals; one is plus and one minus, the middle one is for a thermistor in the internal of the battery so that it doesn't overheat. Check the plus and minus with a tester to be sure and look at the way it mounts into the phone. The corresponding terminals in the phone are where I connect the wires.
Now here is the complicated part, - or negative(black) goes to the one negative copper pin in the back of the phone. The positive +(red) wire however needs to bridge the other two pins for reasons that I would like to find out. The white and green wire got taped up seperately to avoid short circuits and I replaced the battery to hold the wires firmly in place and closed the back of the phone. Plug the phone into a charger or external power pack (DC 5v) and it will work fine with no overheating, I suggest this be monitored for a while as it may vary with other hardware.
There may be better ways to do this, as far as I can tell in my case I am not actually charging the battery, instead the phone is running directly from the external power source. The strange thing is that the software(CM11) battery icon slowly discharges and after about 10 hours tells me I need to charge the battery but never turns off and when I restart it is immediately back up to full.
I have tested with a normal cable and the micro usb is still working even though it is still only working when I constantly wiggle the cable, I have cleaned it and as far as I can see its not going to ever work properly.
It would be good to know why the battery does not chargewhen using this method. I imagine it has to do with the internal workings of the phone that control the charging, discharging and battery temperature.
Making the old hardware live longer.
Replacing the micro usb is doable with a hot air gun a pair of tweezers, a clunky spring loaded solder sucker, a flux pen and two pairs of 3.5 x magnification reading glasses. You dont need any fancy rework station or microscope, assuming you have steady hands, reasonably good eyesight, and some soldering experience. I just tried this myself yesterday and fixed and Ace 3 and two S3 mini boards from my junk pile, and while it was a little tricky, it didn't require any brain surgery skills, just care, patience and some previous smd soldering experience.
Proceed as follows, mask off all of the surrounding components with kapton tape, apply lots of flux from your flux pen, then heat the plug carefully, pointing the hot air across the plug and away from the rest of the board. Grab the (hot) metal can of the USB plug with the tweezers, and gently lift it. Only remove the plug when all the solder is melted, and it feels loose, to avoid pulling off any tracks. Remove those tracks, and the phone is for the bin. Next, clear any holes that are required to mount the new plug, take care at this stage, as it is imperative that the replacement plug sits flush on the board otherwise the pins on the plug, wont touch the pads on the board, and worse still, you wont get the case back on at the end of the process.
To fit the new socket, clean the pads... no really clean them.... now make sure they are clean, and then flux them and tin them. Fit the new plug, and check that it sits flush to the board. Tack down one metal lug only on the can of the new plug. Check again that the pins are lined up, and carefully drag solder them. Check for shorts. Check again... clean the pads and check again. If you are happy, tack down the remaining three lugs, make sure they are flush and that there are no blobs of solder on the tops of them. Clean the board again. Test... Profit
Total time including additional swearing, re-cleaning... re-re-cleaning and re-fitting.. about 30 minutes and two strong coffees.
The replacement USB plugs are readily available on ebay typically around the £2 ($3) mark, but there are several different styles, and they are different, so make sure you use the correct one for your board.
Now back to your question... why does your battery not charge when you tack the wires to it... simple... it is trying its best not to explode. The USB port provides 5V, but the battery needs between 2.8 and 4.2 vots.. depending on its current state of charge, and this is what the charge controller chip within the phone provides. Anything else and the protection circuit kicks in.
I suggest if you don't fancy repairing the USB plug yourself, you get one of those cheap "universal" usb phone chargers from China, they cost about the same as the replacement USB plug, but are (marginally) less likely to blow up your battery.

Good description of the soldering job, the samsung pocket neo is very small but I look forward to having a go at fixing it properly one day, I dont yet have a magnifying glass or solder sucker, but I want to get them. Without these tools the job would be near impossible.
Little update: the phone is charging, I have disconected it and it holds its charge nicely, the internal software just doesn't register the trickle charge it is recieving, I have loads of old chargers and new usb cables and my old second hand phones micro usb port is way too damaged to work anymore with any charger. I use it as a modem principally, so it is connected every day and providing wifi to multiple devices and has no problems with over heating. Now nearly two months have passed and it works fine. Using this method it is possible to completely remove the battery as well. The phone is running directly off the 5 volt power with no ill effects.
It would be convienient to connect it directly to a pc in usb debug mode occasionally, and this is a very good reason for eventually fixing the usb plug.:good:
