Not your typical charging problem... - JASJAR, XDA Exec, MDA Pro General

Hi there guys. I have i-mate JASJAR(htc universal)
symptoms: no USB sync, no charging via anything, EXCEPT when battery is taken out and charged independantly, ie. in other device or cradle charger.
A mate had the phone before me and was in a emergency to charge it, so he bought a not so trustworthy charger and charged the phone, it charged for 30 seconds and then completely died.
I have aquired the phone and am trying to track down the source of the problem, thing is, when I charge the battery externally when it's not in the phone and then put it into the phone, everything works normally, except that the battery doesnt charge when I plug the phone into PC via USB, and there is no USB connectivity.
Sending the phone off for repairs is not an option to me. does anyone have an idea where the battery charging sub circuit is on the main pcb?
A full schematic of the device would also be GREATLY appreciated.
Thanx in advance.
Louis.

It's dead!

My battery went flat and I can't find my mains charger, so I connected it to my laptop using the usb cable, with the intention of recharging it. But it doesn't seem to be charging and I can't turn it on at all. Is that normal? Will it only recharge from a mains charger when the battery's dead? Finally, is it safe to by any odd charger off ebay etc.?
I do not know if that is normal or not. However with regards to charging, I have used a Motorola charger with USB connection successfully in the car and from the mains.
If it is all the way dead, you have to charge with original charger. USB charge will not work. Nor will a Motorola charger work. I think that as long as the charger is 5volts, you should be okay. My Motorola charger is like 3v or something.
Thanks
I had the same problem. It does not charge in the beginning, however, if you leave it connected to USB, it will start charging in an hour or so. damn long, but it's better than nothing...
Tried to keep it connected via usb for a few hours, no luck, guess I'll just have to wait till I've bought another mains charger. There seem to be plenty of cheaper ones on ebay etc., is it safe to buy any usb charger?
This happened to me, and I nearly had a heart-attack until I came to these forums for a solution. Apparently, the phone has to be on for the charger (mains or usb) to actually charge the phone. This is because the operating system of the phone controls the charging of the phone. If the battery is completely dead, the operating system cannot control the charging, and so no matter what kind of charger you use, and no matter how long you leave it plugged in, you won't be able to charge the battery.
The only way to get it to work is to get a bit of charge into the battery directly - not through the phone. In other words, you need to jump start the battery (almost like you would jump start a car's battery). What I did was take the battery to a phone repair shop, and asked them to boost the battery using boosting equipment. Their battery testing equipment will be able to tell you when there's sufficient charge to get it going. Then turn on the phone and plug in the charger immediately once it's booted up (in other words, when the operating system can kick in and start controlling the charging process).
Hope this helps.
PS, there's a post on this forum somewhere on how to do-it-yourself, but in the long run, I found my way to be the easier way.
PPS. Once your phone is back up and running, never let the battery run down completely.
Same happens to Motorola V3.
It is ridiculous design flaw.
This is really annoying, I was hoping to sort this out with a new charger (in the post now) but looks like I'm going to have to go to a t-mobile shop. Will they definitely have something to charge the battery a bit, or should I start looking into buying something to charge the battery at home?
Yes you need the main charger.
I was using my other phones charger(motorola) with my cingular 8125 and battery is completly empty it doesn't charge it.
Didn't wait for a hour but if that works.It's good i love my wizard
motorola V3 chargers do work. used the missus' when battery ws completely dead. interestingly, doesnt work the other way around...... :?:
help with my dead battery
Bdcol
Could you direct me to that post on how to charge a dead battery - I have searched but can't find it. This is a really annoying problem - does anyone know of a commercially available battery charger which doesn't need the phone OS (the battery looks pretty standard to me).
Many thanks

Internal battery is very low!!! Need Help

Hi,
My wizard main battery (wiza16) was very low and the wizard stop with a message “The internal battery is very low”. After coming back home I have tried to charge but it is not taking charge and didn’t turn on anymore. I recently bought a new battery (wiza16, 3.7 VDC, 1250 mAH) thinking that it will work again but still the same problem, wizard is not taking charge or turn on.
Can anyone help me?? What can I do to start my wizard? Do I need to change the tiny little battery (which is inside the wizard)? Kindly help me.
Wizard service manual
Hi,
See if when you connect the power plug the led turns red, if yes....
If Charge light is red when plug in AC adapter, it means the main battery is not charge enough and can’t power on,
You just need to continue charge unit the light become Amber
If not, i think you have a problem.
Check if charger its working and if its pluged.

Wizard Battery discharge completely
Hi,
Thanks for quick reply. there is no light when i connect my wizard with PC. I don't have the AC charger, I have lost that for long and was using my PC usb to charge. trying to get one AC charger.
There was no problem with my wizard, just can't turn on after it's battery discharge completely. Even the new battery couldn't turn that on.
You'll need the original charger if the battery has complelty discharged as it will only charge from the computer if the phone is powered on.
This happened to me before.
There is a trick to giving the battery a quick charge which will give it enough juice to boot the phone up and allow it to charge from usb. its not recommended but works.
You will need a spare usb cable, cut one end of, strip the wires back and connect the red wire to + and the black to - on the battery, only do it for a short period, about 30 seconds while conneted to your computer.
You may need to give it a few 30 second bursts to give it enough juice.
Pop the battery back into the phone and switch it on while pugged into the PC
Took me a few attempts to get enough charge in the battery for it to boot up.
Wizard battery
You can also use a 9V battery to jumpstart your battery. But then you have to be more careful. I connected the 9v battery to my Wizard battery for about 15 seconds, then tried to start up my device. If not successful I started again with 15 seconds jumpstart..
But you can find more information here in the forum: just search for jumpstart or something similar....

huibuh_!
Wizard Battery discharge completely
Thank you all for information. 9V battery method didn't work for me. Looking for AC charger online and get a link (http://www2.dustin.se/pd_5010073700.aspx). Do you think this is the right one? If yes, then I can order.
yea that's the right one but if you have a friend with a ppc or maybe a razor you can use there charger most ac adapters are starting to use mini usb just a way of saving some money even though having an ac adapter is good
could also try and get one of those usb plugs that you can plug up to a wall and plug in a usb cable into the slot
but don't take my word for this wit hmy wizard i haven't had it shut all the way day
if anybody can verify this would work
AC charger not also working
I have got the AC charger yesterday. When Connect the Ac charger first time the red light on my wizard showed for just half second then dissappear. Still let that connected for whole night but no response.
Thank you all for help.
@Keland44, most Razr chargers dont work, they MUST be at least 850mA in order for the Wizard's battery to receive anything. The older Razr chargers are sometimes as low as 350mA, but the never ones are as high as 1.2A, so you need to read the label on the charger itself to be sure.

Yup that is about right,
If the battery is complelty dead, then you need to original charger.
If you have got the right charger and you get a red light and it goes off. your phone might have a problem.
This happened to my last wizard after stupidly trying to dry out the screen after getting it wet which stopped the touchscreen working (i was drying it out while the phone was still on) well my wizard crashed.
Took ages to get it back on but it was very unreliable then one day, it wouldnt go on and charger done nothing. Unpluging and pluging the charger in several times got a red light on.
Sometimes i could get it to turn on, the charger would charge for about 5 minutes then the phone would die soon after.
Your phone might possibly be bricked.

HTC TyTN does not charge anymore.... Need Help

Hi Guys
I have a problem with my TyTN at the moment.
My device is not charging.
Yesterday i put it in my Docking Station and wait a little time.
But Now the Tynt isnt charged.
I think ist a Problem with my TyTN Hardware.
I have all Power Supplys used they i have, but it doesent work.
Can you help me?
Its this a problem with the accu or a fuse on the circuit ?
Sorry for my broken english i hope you understand me.
Regards Patrik Laube
Hello,
first of all, try to soft reset the device.
If it fails, hard reset it.
If it doesn't work, go the service center.
Good luck
The above advice is fine. But you did not say if any of the LEDs are lit.
Do you get the red NO CHARGE LED?
Does your phone operate normally except for not charging?
Mike
Hello
My Phone is working fine but i cant charge it with the original HTC adapter.
I must load the accu with a special loader.
USB and Charge dont work....
And i have no warranty I cant send it to my operator.
When i plug in the USB Cable it doesent make everthing.
I think it was a to high voltage on the USB or the USB Ground ( - ) had a electrical Power for a litte moment.
Have you an idea?
Thanks for yur help.
Regards Patrik
I had a similar problem, which was sorted by a new rom, but I ascertained it was software problem when I realised it charged when powered off.

hi,
try this: when your device is connected via usb, tab on the battery icon in the taskbar on you device, go to the register "advanced" and check/uncheck "When Device is turned on, do not charge the battery when connected to the pc"
thats it

I'm having an issue along these lines, also.
My phone has been working fine untill the other night when I tried to charge it via the wall electrical outlet. It will not charge at all, the battery has been drained to nothing and I can't turn it on. The yellowish light doesn't turn on when I plug it in like it used to.
I don't know if this is a battery issue or an issue with the USB connection inside of the phone. On a side note, when it did have power and I tried to connect it to the USB via the PC; it didn't work. The phone was on, but the computer didn't even notice the phone was plugged in. That leads me to believe it would be a connection issue; but I'm not quite sure.
If anyone has anything they can add to this I would appreciate it, thank you.
P.S. Bringing it to a service center is a bit out of the question in the mean time seeing as it was bought on eBay and funds are limited for the time-being.

Hello, I cannot find the "When Device is turned on, do not charge the battery when connected to the pc" in my device. My Rom is WM6.1 CE OS 5.2.20273 cooked by dvha79_ddt.
My HTC TyTN has the sample problem, but i can use the USB to charge normally. It cannot work using my AC adapter Only when the device is open...
About your Battery Issue.
I'll tell you exactly why ur phone isnt charging anymore... If you have been charging it alot on the USB or pretty much any!! charging on the USB u have killed ur battery, never charge your phone on the USB it kinda sucks they should make these phones able to be Sync'd thru USB without a battery cause these batteries should not be powered thru the USB over Time... from syncing to your pc will kill these batteries i have noticed that when u sync this Tytn Ithru USB and the device is at say 70% it charges up to 100% pretty fast i would recommand to you and anyone who reads this dont sync your TYTN or any HTCC phone for to long to the USB Cause it will Trash your batteries Life down the road... Hope this was HELPFUL.
Cheers

^I'm having the same problem with my herm200. I did the soft reset, hard reset changed ROMs but still the same problem. I don't think it's the usb connector because if it is it wouldn't have been able to charge the phone even if it's turned off. Before I'm able to charge it turned on but it would take a few minutes before the orange led turns on, but when I use the phone or if I receive a text the orange led would turn off it's like the charger disconnects but after a few minutes it would go back again. Now it just wouldn't charge turned on, sometimes it gets worse where it just wouldn't charge on or off.
Now I'm already planning to buy an external battery charger.

Are you using an official 1000mA charger? (Not a 500mA one) 500mA ones work, but they are under-powered and can cause strange behaviour, like not charging whilst turned on or whilst on a call. Similar problems can be found with car-chargers that will not charge until the device is soft reset.
Mike
^no it's not the official charger, I have this usb wall charger called Power Juice (phone and mp3 charger).
Input Voltage: AC100-240V
Output Voltage: 5V
Output Current:1000mAh
Do you think it's because I'm not using the original charger?
fixed my charging problems
The boyfriend told me to try a new cable for my charger so he bought me a 5pin usb cable, tried it at home and it worked! I still need to turn off the screen sometimes but that's ok at least I don't have to turn off the phone anymore. Now my battery charges less than 3 hours.
Hold both SoftKeys and Then press the Power button
Or you can also hold both softkeys and then put your stylus into the reset hole.
answer why it does not charge through the usb
Sorry for the very very late response. Under electrical legislation all hand held electrical devices must be insulated and fused. Some of the chargers that you can purchase are sealed without fuse which indicates that the phone has a fuse contained within its circuitry (or there may be 2 fuses one in each device) .
The problem you have encountered is that you have connected your phone to a computer or mains supply to charge. There has been a surge in the electrical supply either on connection or by un-connecting from these supplies (e.g. connect to the computer as it is booting would see a 65w signal through the USB) and this more often than not blows the fuse which sits on the PCB (printed circuit board) just after the usb connection internally to the phone.
you can either have the fuse fixed for 20/25 gbp or you can purchase a new circuit board or you can use an external charger for the battery. As it is only the power input point that is faulty.
hope this helps
Since we are at this non-charging & battery issue, I would like to ask this question on the D838pro. My battery won't charge even after 24 hours of charging. The red LED blinks thru the whole process. The LED did not turn on to orange or green. It is the battery problem because my spare battery works well. I would like to know what is wrong with the battery as I am willing to strip down the battery. Could it be the battery circuit or wiring that had fired?

Never tried stripping down a battery, some things... well, just don't seem worth it. However as a learning exercise it might be interesting. Without lots of testing on a good battery with a multimeter then I have no clue what the readings should be between all the contacts. (Now there's a little job for you) It is as likely the internal structure of the battery is screwed as it is to be a wiring problem.
If you solve it you can certainly report back here

X10i not turning on / charging

Hi guys,
Suddenly facing a strange problem since last night.
My x10i was running out of charge & i connected to the comp to charge while i was working. I noticed the charging speed was extremely low, so i restarted the phone to see if it would help. Did not.
Thought there is some problem with the cable, used a different cable as well, but no use.
The slow charging had stopped and eventually the phone died.
Tried connecting to the socket & charging, still no use.
The red led blinks when i connect the phone to a charger via the usb or the socket.
needless to say the phone does not even boot up now, obviously for no charge...
any ideas wat maybe wrong or wat i could do ?
please advice
Have you tried to let it charge for some time in off mode? As long as your battery is not dead, and the phone get the right voltage through the USB connector it should charge in an "emergency mode". This is a slow way of charging, but allows for charging without any electronic circuits to monitor it, it is not the same as the charging screen that usually displays when you connect the phone while it is powered off. Usually when a phone is completely discharged it needs to be connected at least 15 min, sometimes a lot longer, before the electronics kicks in, and starts the speedcharging.
My best advise would be to connect it to the mains charger, or a USB port you KNOW supplies power. Some laptops cut down on the powersupply to the USB ports when they run on battery. Let it be connected for a long time (several hours), and then try to power it on again.
If that does not help three things can be wrong
1. Somewhere the USB connection is broken, either in the cable or in the connector on your phone (or on the PC's connector, but that is less likely).
2. The battery is dead, modern batteries contain circuits that actually disables the battery when any given parameters gets outside the defined limits. This is to prevent the battery catching fire. On some batteries this renders the battery useless, and you need a new battery.
3.) The mainboard of your phone is dead, and hence nothing works, can be ruled out if you can borrow a battery from someone to test if your phone works then.
I hope a good and long charge can sort out your problem, that is the easiest fix, and it is free.
Hi O_K,
well, i have been charging (or trying to) the phone since it died last night.
i have used different chargers & different modes of charge (through the system & the wall socket) - no joy at all.
the LED blinks red a couple of times when connected.
Very occasionally, the SONY ERICSSON logo (startup) shows on the screen & it switches off again, back to the blinking.
So charging for a long time & through different chargers has not helped.
gonna try a different battery now to see if that can help.
Thanks for your response!
well, tried switching chargers & batteries.
The problem seems to be with the charging unit on the phone (USB)
with any charger or battery, wen connected the led blinks (like wen the phone is charging), but there is no charge happening.
eventually the phone dies, even if charging
any ideas?
There is a thread some where in this forum for fixing the same problem you have...I don't remember the exact name of the thread..if I find it I'll post the link here..Anyways what the guy did was
-Pull the battery out and connect the charger till the led turns green.
-put in the battery now and charge the phone...
and I think that was it.
Hope it helped..
EDIT: Found the link.

[Problem] Battery lost quick charge capacity ?

Last night I put to charge my XT1563 with its motorola charger it dispolayed the message Turbo Charging as always. This morning phone was dead, no signs of charging or recharging whatsoever. After a while of having it connected to a "normal" charger it started again to charge, but hooking it up with turbo charger does nothing, I mean it simply ignores the fact that there is a cable hooked up. I have also noted that my computer no longer sees the phone, whereas before it always detected it and asked what to do with it.
Anybody has had the same problem? My guess is that the battery needs replacing as when I use my motorola charger on my wife phone it pops again the message "turbo charging"...
Any help is appreciated.

Switch your phone off at night and check your battery level the next morning. If the battery can keep his charge no replacement is needed and a factory reset could do the trick.
It does keep the battery level and already did 2 FR - still no turbo charge ,not recognized by PC.
Looking around for FL40 for a battery replacement but cant find one available .....
Personally, I think that a battery that doesn't charge on a certain charger, but can hold a charge once it is charged is not the principal suspect. Check the connector, the cable, the software, etc before replacing the battery.
