I got a used wizard today,it is a few weeks old I also got a cradle with it.
I pluged in the cradle to the USB port and the charger to power, after playing with it for 1-2 hours I placed the wizard on the cradle to charge and after a few mins i noticed that it was over heating. I removed it from the cradle right away and noticed that the battery was droping 1% every minute or so. After it was down to 27% i removed the charger and left only the usb connection and placed the wizard on the cradle again. it was charging fine, when it was up to 90% removed it from the cradle and again was droping fast.
When it was down to around 25-30% of the battery I did a soft reset and since then I can never get it to start again also the red charging light does not show.
What the heck is wrong with it? I also get a light burning smell from the bottom of the wizard where the connector is located.
Any help?
I need your lights guys.
Don't like the sound of the light burning smell, that sounds like an electrical fault. It looks like your battery has died and the wizard battery setup is well known to do this. You need to plug it into the official mains charger (not the usb one) as this has an output of 1A, enough to kick start the wizard battery into life and start the charging. You need to wait a short while though before the light comes on. If this fails try to get a new battery and try that. Any more light burning smells and it needs to go back to the supplier.
I would suggest that you send it back to replace/repair. The rapid dropping of the battery power suggest that it is using power somewhere (illegally). I've heard cases of battery caught on fire, etc. and I won't suggest you to use it anymore until you sort out the 'burning' smell.
First of all thanks for your replys.
I pluged the charger on it and the red charging light came on after a while.
charged for over 6 hours and its still red? I think after been charged should change to green? right?
anyways after all that still doesnt want to turn on. I got it to start a couple of times but only to the point that shows the splash screen with the rom numbers and then it turns back off.
Should I give it a smash across the room on the wall? done that with some other things and worked just kiding.
Forgot to add that up to the point when i did the soft reset the device was working fine except the charge drop. Soft reset was done while it was working ( turned on)..... if thats any help.

That ain't gonna do jack sh1t to it. If it can't start to get into bootloader, it can't flash....and it's not a flash issue.
Usually the red light means power but not charging - happens to my qtek 9100 when I let it get too flat and I have to remove and insert the battery while the mains adaptor is attached - others have to 'jump start' the battery by directly connecting to a PSU - I wouldn't do this with yours.
From what you have said it sounds like a short somewhere. Any signs of water damage? Warranty? What Wizard do you have and what country are you in?

I got the wiza 200 O2 xda mini S from a guy in UK from ebay. The idiot sold me a cradle for it with an adaptor that says 12V on it (Like an idiot that I am i just noticed that) but then again how am I supposed to think that he gave me an adaptor that its not made for it when it says on the back of it "for Imate - Kjam". Do you guys think thats what burned the **** out of the unit ?
dont forget that some times turns on shows the ROMS numbers and turns off.
No water damage... I think its on warranty... I live in Greece.
Might not be the cradle - it could be it steps down internally to 5v. Use a meter and check what it outputs to the phone. Warranty with XDA's are 2 years to the *original* purchaser. As they are only supplied with an airtime agreement then that isn't you.
Richard
have you tried changing batteries to a new one? Seriously, thats the easiest thing you could do right now and you could actually get results.
Ok this is what I did.
Removed the baterry from the device,
got a 12V 1 Amp power supply that I had lying around and give it a few shots connecting it to the battery giving it an electro shock.
(If you're going to try this be very carefull.<<<< DONT LEAVE the power supply connected to the battery>>>> just give it a few shots 1 second on and off.
That was it.
It started working, device turned on and now its charging (I think) yellow light is on.
I'm going to leave it on for a few hours and see what happens.
Wish me good luck. I'll let you know soon.
ok... this is what happend.
Battery is drained and its not charging due to a blown fust on the main board.
I open the phone and placed and solder a little wire over the fuse.
Still does not charge. ^%$#%$#$^%$*
Before I replaced the fuse or should i say short it the yellow light would come on for a few min and then red again. Now when I charge the battery with another external power supply the pda comes on for a few mins and then dies again. ( no charging light whatsoever).
Does anyone know where to get a mainboard for it and about how much it costs?
Asking for help again.

Hey man, sorry to hear about that.
The best you can do is to claim your money from ebay.
You probably killed it when you pluged in the 12V PSU. That's 230% of the normal Volts! Otherwise sell it for parts.
I'm in the process of claiming the money back from the IDIOT that sold it to me.
Lets see if that part of Ebay works as good.

Doubt it. Did you ask the seller for help before opening the phone and voiding the original warranty on the device?

Not a good idea IMO as now the blame is on you as previously he may have been able to get warranty service from the original vendor.
Richard
I did ask.
He is not the original buyer.
what was I suposed to do.... track back 2-3 buyers to find the original... send it to him so he can have it repaired? Anyway it was out of warranty because of the burned fuse that says that some other charger was used with it.
I had a similar thing happen but fortunately not as bad as yours. Twice now my battery has mysteriously drained completely. The last time when I tried to turn the unit on, it flashed the boot screen for a couple of seconds then poof, no more juice. When I plugged it into the USB port, nothing, no lights, no charge, no recognition from Activesync, I thought the unit was fried. I use Tmobile and got to admit they did send me a replacement fairly quickly. Before I packed up my unit I thought maybe I should plug it in using the wall charger and presto, it came on and is working fine. I have no idea what causes this but do know that if the battery is completely discharged the USB port can not over come this to put a charge on.
Same thing happened to me, kind of strange though. The charge was perhaps 70% to the best of my knowledge. I flashed it with Mr. Clean ROM and booted it up.. it came in fine into WM5, then it started the installation of the 3 progs or whatever comes with Mr. Clean.. after the second finished the unit just died *poff*. Screen blank, no responce to power buttons or any other buttons for that matter.
I've tried taking out the battery for different intervals of time, no luck. I've tried using the AC charger, no luck. No lights, sounds, telepathy or matrix ****.. it just lies there like a dummy phone.. hmm what to do. Bought it from a guy in UK (im in sweden) on eBay, don't think I will have much luck there.. even though it's brand new...
Any thouhgts?
I have had this problem - I bought a replacement battery and all is now fine. Another thread in this group states that the battery cannot charge without the OS up - so if the battery is completely discharged then it is impossible to charge through the phone. The only solution seems to be somehow to charge the battery directly - as appears to have been done earlier in this thread.
Chris
p.s. if anyone knows of another way to do it I'd be interested to hear as I'd like to revive my old battery and keep it as a spare
Hello to you all,
My new XDA Exec has developed a fault. It works OK when plugged in to the USB on my laptop or charger but when running on battery will only do so for a short time. In fact a matter of a few minutes.
The battery indicator shows the battery at 100% when charged but the phone turns off variously at 95 - 98%. I tried a soft reset and not change.
I tried discharging the battery using small lamp then recharging in the phone. The battery indicator did show a lower %age 80 ish but not as low as I would have thought. Subsequent charging made no difference and the problem persists. Has anyone seen this before? Any bright suggestions?
Many thanks to you all for you time.
Cheers

You battery is dead therefore you would need to change. You are not unique with this problem. That is common issue for Universal (exec) batteries. For your new battery: dont charge with the USB cable and charge when is completely drained.
Hi Bulldog,
thanks for the reply and the info. Regarding charging the unit from the USB port. Does the unit not begin charging as soon as it's plugged in to a USB port? Is there a way to prevent this that you know of? My phone was normally charged for about half it's life from the charger, half from USB.
From what I understand the LI ion batteries don't have a charge memory due to milisecond pulse charging so pardon me for asking but what does the total discharge do for the battery? Obviously it does something but what? (Not doubting you but I'm curious). Is there a away to ressurect a defective battery such as the one I have currently or is it a lost cause. I know some batteries can improve with either heating or cooling by about 20 - 40°C from normal operating temeprature, have you any experience with this?
Do you know if some makes of batteries are better than others?
Please pardon the inquisition but as I spend a lot of time in remote areas it's often quite handy to be able to bodge rig stuff in order to effect a temporary fix and it seems any bits of knowledge help!
Once again many thanks

Hi, I have the exact same problem...works fine when usb or mains connected but only for a few minutes when on the battery. Usually when I give it some heavy task stuff it will suddenly just blank out the acreen and die.
I'm going to try and do what's suggested on the wiki page about masking off the charge indicator contact with tape - run the thing down and charge up again.
otherwise it's a new battery - not expensive - and plenty about on ebay.

Hi Piran,
Be Frank I am not battery specialist. Therefore I cant give a deep explanation what makes the Universal Battery having so many problems with USB charging. For my understanding it is the slow charge which leads to Battery overheat. Therefore All the post here regarding the Battery problems suggest not keeping the universal charged with USB. Just search for Post for "battery problems" and you will find few "explanations"
In Regards whether you could reverse your battery issue. From my previous experience I would say the max the you can get back is some 10-15%. However in your case the issue seams more severe as you device turns off by 90-100% therefore I think you would need to order new Battery.
following procedure I follow to drain my battery:
1) Turn off You Phone Radio (important)
2) disable the "Turn off Backlight" and put your device brightness to "full"
3) let your device drain the battery by him self( prevent doing anything with your device during this time. I found starting application, touching screen etc. leads that the device request a pick of power which the battery is not able to provide and turns the device off.
4) after certain time your battery will be to weak to keep the device on.
5) push the "power button + backlight button + reset pin" to put your device in to bootloader mode. (your screen will be almost off just some info like SERIAL or Bootloader Version will be visible)
6) again keep the device in this mode to drain as much you can until you cant see anything on the screen.
7) repeat this point6 few times as sometimes the device turns of but after trying again the button combination you can put it back to bootloader.
With above the aim is to drain the battery much as possible. After that you charge your device with power connection for min.12 hours. I guess you will gain few % however repeat the draining and charging procedure for next couple charging cycle to see how much max you will get back.
Good Luck.
I faced the same problem with my battery on Universal.
After a complete drain, the battery wont recharge:
1) Connecting the power cord it starts the boot process, after few seconds the power led ligths in red once, the screen blanks and the boot restarts again and again.
2) Using the usb cord the power led flashes in red without further actions.
I have to throw away the battery, I guess.
Thanks for any comment.

Cesare, you right when you plug in the device it will boot up. However after while (ca.10-15) when the first initialization complete you could go and switch off the screen(with power button) which takes allot power. Anyhow in your case it is really strange as your device behaves like it has no battery at all. there could be 2 things leading to that.
1) your battery is completely dead ( check with a voltmeter to confirm)
2) or something wrong with your Connection clips (battery and device) you could again check with a voltmeter whether you get any juice on those clips.

Hi Bulldog.
I think that the 1st one is the rigth hypothesis. I'll check with a voltmeter.
The connection clips are ok because the backup battery works perfectly.
To drain that battery I connected an optical usb mouse until the mouse ligth went off. Do you think that this action is the reason of the death?
Many thanks again

Cesare, your battery my not complete dead but it is to weak to lighten up your Universal. Said that leads to bad thing which is: you can only start to charge battery when the universal has come out of bootloader mode.
I had such case ones, after not using my device for very long time the battery was completely drained, And as you described the device keep booting after plugging to the power. However after certain time ( I think some 15-30min trying) suddenly I was able to start up. I am not sure whether that would help to overcome the booting mode with less power but you could try to take out your sim card and memory card and try booting. ( again not sure it will help)
Guys - a quick update from my previous post.
I was suffering a sudden power outage at about 75%-85% battery power - just a blank screen - power gone. Didn't happen when mains connected, only on battery.
Well, first things first, I thought...dodgy ROM for WM 6 - so I tried a few of them - Ivans, Ranju's and Beastys - no change - still this power out.
Read the posts on this forum and thought - gotta be the battery's fried.
Sooo,
I ordered a new Genuine JasJar battery and installed it - (let it charge for 8 hours) - since then...no problems - no crashes, stalls or blank outs.
I'm running Ranju's 7.4 with spb pocket plus - htc home, etc,
As a point of interest my old battery stated 3.9Volts when I put my meter across it BUT - a voltmeter isn't drawing as much as the universal - when 'under load' from power intensive apps - hence you think you've got a battery putting out the requisite power when you haven't.
This was a real niggly problem to sort out with potential culprits all over the place:
Bad battery?
Bad ROM?
PCB crack?
Hardware Fault?
At the end of the day it's good to have spent £32 or so and simply got rid of the problem totally.
I'd say to anyone who's getting outs or blank outs at 80% power or below - your battery stuffed and no amount of mucking about with ROM swaps, Freezers, charging/ discharging is going to stop it blanking out on you.
I'd also like to say how appreciative I am of this forum with a great deal of knowledge available from so many users across a very broad spectrum of skills and experience. Nice one!
Hope this helps,

Hey all,
Having served me faithfully for 18 months now, my TyTN has finally given up the ghost. It refuses outright to boot.
Not a splash screen, not a backlight, no response at all no matter how long I hold that power button down.
When I plug it into the mains it displays reddish on the right hand LED, having left it plugged in for a while it stops displaying even that until I unplug it and re-plug it.
I've tested the battery with a voltmeter and the power on the phone with a circuit checker, there's not broken circuitry and the battery certainly generates a current.
Though it's not TOO urgent, as I have a backup phone (Nokia 3220, ugh) unlocked and in use, and it's not TOO horrible as I was about to order a Touch Pro anyway, I'd like to keep it strictly unbricked either for sale or for backup.
Any thoughts on either:
1. What the problem is, I'm absolutely baffled.
2. How I might go about fixing it.
Thanks, Forlornity
If its only displaying a red LED when you plug it in that generally means that the power sensor has been confused or the battery isn't touching the contacts properly.
Are you using the supplied charger or a 3rd party one/usb connection. The usb and most 3rd party chargers don't deliver the right charge. If its underpowered it may not trip the charging sensor.
Try pushing the battery tightly against the contacts, I had a problem whereby the contacts had been pushed in so the battery didn't connect properly.
Clean the contacts with a cotton bud and isopropyl alcohol (surgical spirits) to remove any corrosion. DON'T USE METHYLATED SPIRITS!!! It leaves a residue.
Thats all I can think of now.
Cheers...
Isopropyl you say?
It's a pity, I've actually got meths handy.
I'm using the stock charger, I suspect I might be suffering a RLOD, but none of the usual methods are working...
I'm gonna see if I can get hold of a charging dock for the battery from expansys or suchlike (unless anyone knows anywhere better?), see if that does the trick, if not, new battery, then if THAT fails I'll have no idea
Thanks for the tip on the isopropyl!

I have the same problem, and new battery didnt help! anyone got solution for this problem? I menage to charge battery with 2 wires, and phone starts, but it wont charge! i mean orange led is on, and it says CHARGING, but battery % is going down down until it reaches 0%!
After several cycles on WP7 the batt was fully drained and now it won't charge (charge LED goes on for few seconds and then goes off). It won't load either, just switches off on DFT screen. Batt is standard.
Guess it is critical not to allow batt to drain fully on WP7?
Is there any solution to this?
Thanks for any ideas.
Had a similar problem with Android...battery drained completely and wouldn't charge. I solved it by cutting the end off of a spare USB cable, removing the battery, and charging directly from the cable (red wire to positive/black to negative). After about twenty minutes I put the battery back in the phone and it booted Right up. Or, if you have more sense than me, you could just pick up an external battery charger...I'm just the hack apart a cable and do it caveman kinda Guy...

I can confirm a similar experience; I thought it was worth trying the fully-drain-then-fully-recharge regime suggested elsewhere on these forums as a means of extending battery life, which does struggle a bit on WP7.
The fully discharge bit was easy, but it is worth everyone bearing in mind that magldr - as advised, I believe - will not allow the phone to charge. As a result, I was getting into WP7 (just) only for it to almost immediately shut down. But it was at least doing a small amount of charging before it did.
After a sweaty fifteen minutes or so of restarts (I was having to take the battery out to force the restart as it wouldn't start on the power button), it decided it had enough charge to...well, charge and all was well.
My suggestion would be not to risk going beyond the critical warning WP7 gives, at least until magldr is able to offer charging.
Almost the same issue here, without having let the battery fully drained...
I can't charge my hd2 anymore.....if it's turned off.
But, it Can be charged if wp7 is running! I don't know why...
I had This issue when I received the phone. It took me a whole Day to charge the battery the first time : orange LED turning off after 10seconds (HD2 switched off or in wm6.5
Once the led is off, can't turn the phone on or charge it again until I remove and put the battery back.
It was in summer so I thought the phone was too hot, so I cooled the battery with a fan, replaced it, retryed... At least 10times, and it finally charged.
SO weird, I'll test This again with wp7, who knows?
I am wondering whether it is some kind of magldr bug?
I'll try the trick with the cable directly to the batt. It is not very practical though if you drain your batt, where there is no access to spare cabling.

This should be put into the sticky rollup thread for people who have let their batteries drain.
Why dont you do some pics bud and create a topic?
I am cutting the cable as I write. Will take some pics.
If your battery drains completely, just remove it, replace it back. Without starting the phone, connect it to your PC. start and enter the bootloader. You'll be then able to charge. I did it like that last week.

Less of a bug and more of an unwanted side-effect of having this excellent capability, I think. I seem to recall that the developers are aware and looking to see what can be done.

I guess it is possible to completely drain the battery, in which case this won't work. But if there is some power, removing the battery and replacing it should kick the phone into life for long enough to do this. This was going to be my first try if persistent rebooting hadn't eventually worked.
having this problem and definitely charging below the amount...
i cant fully charge the battery as well
Like I said, if connected, but not started, to your computer, you'll have enuff time to start it then and entering the bootloader, of course, you gotta be quick for this to work.
If it doesn't respond, don't laugh, confirmed to work, remove your battery like explained and put it for some mins in the fridge before replacing it (it's only chemistry playing here, somehow better than cutting a USB cable in 2).

"storing them in the freezer might be more practical. These kinds of batteries lose their charge after a few days when kept at room temperature. But they'll retain a 90% charge for months if you store them in the freezer. Just like alkaline batteries, you'll need to wait until they've warmed up before using them. However, this isn't a problem when you need new batteries for your digital camera or other electronic gadget. "
I suggest you to be more polite when answering and learn your lessons before posting!
I finally made a dual boot Android/WP7.
At first, Android said my battery was fully charged, just like WP7, which is totally impossible as I used MAGLDR to format the SD card (wp7 & android partitions) and that it took me almost 1hour, without any possible way to charge the battery while I'm in bootloader mode.
But when I turned the phone off, plugged into the wall.......TADAA It was finally charging, with phone turned off
So, it seems that dual boot may be a way to solve this issue

You're arguing against yourself here aren't you? Cold may be fine for storage but you need heat to coax a little more power out. You even say 'you need to wait until they've warmed up before using them'.

Wrong idea, sorry guys.
I thought that HD2 was charging since I installed WP7 and Android in Dual Boot. But it's a fake : if the phone is turned off, and that I plug it, the orange led turns on. But that's all, even if I unplug the phone, the led remains turned on !!
And now, Android as well as WP7 are telling me that the battery is fully charged but I'm sure it's not even 50% full.
So this is what happened:
the phone discharged fully and i connected it to charge. then i got a flashing red led. seeing this as a bad omen i tried to turn my device on - no luck - it wasn't responding.
i unplugged the charger and plugged it back in and again the same result, then again..... and i got a solid red light. so after a few times of messing about with it , trying out a few sources of power and such i got it charging (the battery logo appeared). The charging lasted for ~30 sec and it went black.
So after that the n4 is completely unresponsive. No flashing leds no backlight on screen, NOTHING.i tried out a few chargers and cables and beside those i used a genuine n4 charger (it's 100% working - i tried to charge another device). i left it there for the whole day to charge thinking that maaaaaby the battery ran to a complete 0 and i just need to give it time, as you probably guessed it, that did nothing.
In fact, i think the phone is not charging at all. The reason i think so is because the wall charger is emitting a faint high-pitch squeal regardless of the fact that the phone is connected (it should be squealing only when it's plugged into socket and the phone is not plugged in it)
so TL DR:
n4 is completely dead, no signs of life. The things that were tried:
a handful of chargers and cables that are 100% working on other devices
trying to boot with a combination of volume buttons pressed
holding the power button for 60 sec. while plugged in
prolonged charging (~7 hours)
verbal threatening to sell the damned thing if it's a serious problem
so that's that. i should get my tools back from a friend on monday. i'll try to take it apart, maby there's a loose connector here or there or something. Any ideas what i could try before that?
Some searching around the forums wouldn't hurt. Try this for example.

thanks for the link, that seems to be worth a shot.... i'll be able to take the phone apart on monday, that's the earliest i will be able to try it. i was wondering if there is anything i can do until then to remedy the situation. I mean i'm really getting a kick out of my old sony erricson k300 but i kinda prefer the nexus and would prefer to fix it asap.
ok i fixed it
i used a 3v source and held the contacts manually for 5 min. that returned it to the red blinking led state and after leaving it to charge for 5 min it returned to the battery icon on screen. thanks for the info again.
