XDA Mini S + USB Charging - 8125, K-JAM, P4300, MDA Vario General

Not sure if this is right part of forum, but here it goes.
I am having an issue with the charging of my O2 XDA Mini.
If my battery dies, with still a small bit of power left in it (enough to get splash screen) and I go to charge it works fine no problem. Now over the wkend my phone died on my and I left it till this afternoon when I tried to turn on, it wouldnt turn on at all (not even splash) because obviously the battery is completely dead. Now when I go to plug it in, it wont charge, from USB cradle, the little orange light to say that its charging doesnt even come on.
Last time this happened I eventually got it to work via a friends socket (plug) charger, rather than USB, charger. Is there any reason for this or anyway that it can be fixed that even when the battery is completely dead I can charge it from my USB cradle.
Any help would be apreciated.
Thank you in advance

Sorry to bump this, but does anyone have any idea. I beleve the cause of this is due to the fact the USB power from the PC isnt enough to get the charging process started, is there anyway to get this done via the cradle.
Thanks

You'll need to use a charger that plugs into a wall socket I'm afraid. This happened to me once & that was the only way I could get it to work. If you search on Google, you'll find methods that involve a stripped down usb cable, but a wall charger is definately easier.
Good luck.

Should any usb based wall charger work?
I have a Motorolla one and Ive tried that but that didnt work.
I know for a fact that when I use my friends one it works and will charge, but he aint round for another 2 weeks

You cannot charge a totally flat battery through usb cable using PC,cuz it only supplies 0.5(500)amp,whereas to get the dead battery back into charging,it requires a supply charge of 1.0(1000)amp,secondly you can only charge the phone via usb if it's working normal and not when it's dead,as you cannot boot into OS.
Therefore,it'll only start to charge with a 'Wall Charger' which only supplies 1.0 amp,your friend's Wall (Mains) charger must be suppling a 1.0 amp charge.You cannot even charge it with the Motorola usb charger cuz it also supplies only 0.5 amp.So try to get a Wall (Mains) charger to get it start charging.
OR,
Yes! you can Jump start the battery using Motorola charger,but you'll have to sacrifice the motorola charger to do it,as you'll have to cut off the usb plug of the charger cable end and attach the 'Red' wire to the '+' (Possitive) connector of the battery and black wire to the '-' (Negative) connector of the battery and give Shock Charge to the battery for 10 seconds,repeat this for 4/5 times,it'll give the battery a jump start and will increase the 'Pulse' level of the battery,after that put it in the phone and check if it loads up,if it does then you can charge it via usb cable connected with PC.
Good luck
BTW ! there's an excellent thread regarding charging to avoide the battery to go flat and saving from getting into this situation,it wud be very info for you,check it also :-

Help! My phone isnt charging!!!

Hi, my phone went out of battery during the night.This morning Ive connected to the chsrger but it doesnt charge,i havent got a 2nd battery and when I connect it to the usb nothing happens!!! Why it isnt harging? What do I do???. Answer me as fast as possible please. [email protected]
have u tried the wall charger or using a different usb port
Original charger and patience
Are you using the ORIGINAL charger and are you LEAVING IT FOR a while. If the battery went completely flat it takes some time for the MDA to recognise the charger (no light then all of a sudden it starts charging) . Don't know why. I'm not a techy but I'm sure someone here will tell you. Frightened me when it happened, but I'm sure I found the above answer on these pages.
Try taking the battery out and in again then try a different charger as it is more likely to be the charger/socket than the phone.
Another suggestion is if you have an old charger that you don't need, chop the plug off it, expose the wire and hold them to the correct battery terminals ont he battery. IE. positive to positive, negative to negative, the terminals are labelled on the battery.
After 5-10 minutes this should have jump-started your battery and your device should work and it should now charge.
Yeah - i had to do what Paul said, and it worked. TO be honest, I didn't expect it to.
For more details, see:

I had this happen to me as well. I tried 4 different chargers, in wall and via usb pc cables. Eventually I took it back to Cingular and they told me my battery "failed" and gave me a new one for free.

HTC not charging, battery dead?

Helloes guys and goils.
I have a HTC wiz, and for a good few weeks now I have had problems with it.
First off, It would NOT charge through the Wall Socket OR USB, I let it run down over XMas and it's not been the same again.
It just will not charge or come on.
When I plug it into USB it looks as if it is charging, with the Orange light and The power bar turns to the socket looking thing, but when I leave it to charge it just goes off and doesnt come back on.
When I plug it into the wall socket the HTC does not respond.
I have been asking my mate in work to put it in his and charge it via HIS wall charger, which has worked a few times, but I seem to be getting a very awful run out of my battery.
I am thinking it is the phone and NOT the battery as i first thought, I dunno, im scared of throwing up £30 notes on a new battery only to find it is the phone.
What do you guys think I should do?
I heard somewhere that it is a SOFTWARE based charge and not a hardware based charge, what does that mean?
DO u think a flash would help it? I cant see it myself.
Or is my HTC just goosed?
Well
I can speak from experience when I tell you my wizard nuked 2 batteries...
how I dont know.
Hopefully one of the gurus can shed some light on your situation

If you do replace the battery, look on eBay - I got a new 1250 mA battery (there are also 1100 mA versions, don't get that) for $13.99US including shipping - works great!
Make sure its nothing simple... Try the USB cable plugged directly into the computer without using a USB hub (if you are) and different USB ports on the back of the computer. Also try different outlets for the AC adapter. If still nothing else I'd even ask for help from your local cell phone store (put on a sad face) and see if they'll lend you a power cord and or swap out batteries to see if they can reproduce the problem on a different Wizard, battery, etc.
There has been many posts on this subject with several different fixes.. i would suggest searching and reading and you can find your answers
My case
Hi,
I had somewhat similar problem with mine. My porblem was that I bought the Wizard with a Motorola charger. It had the same mini usb plug and when I plugged it to charge, the led on the wizard was orange and the Wizard indicated its charging, but the moment I unlugg it, the battery indicator was coming back to its previous state. My solution is to use the PC USB to charge it, on a couple of occasions I had the battery completely drained and had to "jump start it" by connecting the wires from the usb directly to the + and - of the battery. Even used once my good old AA Ni-MH charger to jump start the battery and it worked.
So perhaps you are not getting power from the cable, why not try with different charger or charging from another USB source (PC).
Hope this helps
Just happened to me tonight. Thought that my Wizard was toast as well.
I merely took the battery out for 10 minutes, put battery back in, and plugged device into original wall charger. All is well now.

The Charging Method Thread

Hey everyone.
I figure we could chat on what method you prefer on charging your wizard.
Do you charge always by USB?
Do you only use a wall charger?
A combination of both?
And why? Is there a benefit for using a certain method?
I try to always charge with the wall charger.
I use usb at work - when I need to, but find that it is more of a flash charge, that does not last nearly as long as the wall charger.
Just my 2 cents
Really I heard someone saying charging with a USB saturates the chemicals better?
not sure though.
as with any chemical, the longer the "cure" time, the longer it lasts.
My wall charger charges it too quick and it dies quicker. USB seems to last longer. Also, I have been using a wall plug usb adapter for a long time (the kind you stick into the outlet and plug a usb cord into it) I never had an issue. it wasn't untill i used the original wall charger that I started to have some problems (like I bought a brand new battery and brought it in from the cold (winter) pluged it into my phone; kept my phone off and charged it. apparently the batt got so hot that the plastic covering cracked. the stupid thing was that the batt was not room temp... but I'm afraid my wall charger is deffinately retired. I had the old batt for over 2 years, maybe even 3 and so far it has held up pretty well with usb charging.
Still holds up pretty well if I use usb.
Note: on the wiki they say that the Wizard last about 11hrs on a full charge. that is a blatant lie! I have had it last about 2 days (like the nights I didn't go home) the batt never dropped lower than 30% ever!!! untill I flashed it to a different rom
I posted a fix I think works for me on Merlin's Slim rom 6.1 ver2
It consists of registry settings and and a cab file that should adress your power issues. have fun lookins
I like charging with charge
It takes longer time to charge by usb than using wall charegr

i charge it overnight with the wall charger.
however, since i have started to play on it at work, i bought a wind up usb cable, hacked the wires inside to only leave the power connections, and i bring that to work to recharge it on the computer. call me paranoid, but since the tech support guys jump in and mess with the computer remotely i dont want any chance of them digging thru my phone
and if i have to have to charge it in the car, i have an old fm transmitter you can plug a flash drive into and it will play mp3s...so i plug my phone in there instead and viola el cheapo car usb charger
What lasts longer?

Wizard not powering on or charging

Hey folks,
I've been given a Wizard that isn't working, but I get to keep it if I can fix it . Just now the the problem is that it won't power on and I can't get it to charge. I don't have any of it's 'original' accessories (eg USB cable and charger). The USB cable I have is a 5-pin, which I believe is the correct one for this phone, but plugging it into my computer's USB port isn't having any effect, ie it isn't charging the phone. I have the charger for a Motorola Razr which has the same connector to plug into the phone, but when I try to charge it with this nothing is happening. I don't know if the phone is a G3 or a G4 and I don't know how to tell which it is. Can anyone give me some help here?

As the battery is fully discharged and dead,It won't charge through usb cable with pc,as it only provides a charge of 0.5 amp,it'll also not charge with a Motorolla charger,it can only be charged through a wall charger which is capable of giving output charge of 1.0 amp or you can try a 'Jump' start the battery.But if the battery is faulty,it won't charge at all,you'll have to get a new battery.
Thanks for the reply zabardast.
How would I go about jump starting the battery? I'd like to try it before I go out and buy a new one.

How to 'Jump start',read my post in this thread,hope you get it right and working.
http://forum.xda-developers.com/showthread.php?t=374108
if you're good with electricity and have a DMM or Fluke you can also check the resistance on the battery and use a steadysize capacitor to try and jump it. it might burn the battery but it doesn't work anyways so you don't have much to lose.
the capacitor size can be calculated using:
C(capacity) = 1/wR - where w is the network frequency.. wherever you live. (should be easy to find it. usually 50hz) and R is the value you see on the DMM.
buy that capacitor and charge it using either an AC source or another wizard battery (fully charged) even tho i doubt it would have enough power to charge the capacitor... and then you can jump your battery. an AC source would be a great option since you can set the frequency to the exact network frequency in your house.
Hope it helps..
Iv'e actually had similar problems, and I've oddly enough found that if I used the car charger it would turn it right on. I went to EVERY Cing/AT&T, T-Mobile store and used every charger and nothing. I work for Asurion so I see this happen all the time, Im wondering if I just replace the battery with the High-Capacity type if this problem will be over.
Also just a side not, but it only seems to happen when I leave it off the charger and it shuts off by itself
yep
i had the same problem. and as of today just bought a new battery! my love is fine and alive again!!! the battery is only around 10.00 and is well worth the money to have my babe back! do the same man! you WON'T be sorry ... and it's worth 10.00 not to have to mess with tryin to jump it.

how to charge htc 8125 with no original usb cable and(or) without orig. wall charger

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

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.
