Hello,
I've a Wizard that is approximately 20 months old. Yesterday, before I went to bed, I set the alarm clock on the Wizard, put it next to bed and went to sleep.
This morning upon waking up I tried to switch on the Wizard but it couldn't. Firstly, I thought the battery was discharged, so I tried charging through USB on my computer -- it wouldn't charge or start. Then, I tried charging on the default charger -- again nothing.
I tried removing battery and soft reset - nothing. It's really weird, yesterday I left it working, no-one has touched it and today it's totally non-responsive.
Any ideas what might be wrong/how can I bring it back to life? Would a hard-reset help?
Regards,
1. how much charge was in the battery last night?
2. is your battery 20 months old also?
3. do you have a spare battery to try?
4. do you have many applications, music etc. on the device?

Unfortunately I can't remember, however I have an alarm which sounds periodically when the battery is below 20%, so I'm guessing I had at least 20 percent. Could be wrong, of course, but most likely above 20%.
2. is your battery 20 months old also?

I don't have that. I guess I could go to mobile phone service shack and check there. Do you think it's the battery?

The Wizard came with a 64MB card I think. I had around 10MB free space. 3-4 applications, 2-3 mp3s. Nothing unusual.
Same thing (sort of) happened to mine after about 187 months. I was using mine and it hung up. I hit the reset button and that was the end of that. Even when plugged in it does nothing. Tried a hard reset... nothing. Soft reset.... nothing. Dead. Zip. Nadda.
Good news? Replaced it with a Kaiser!

Mine died too when i was flashing...
Leave the phone in the original charger for a while and see if it picks up...sometimes it comes back to life by doing that...
If that doesnt work, try a new battery, you might be lucky...
A somewhat strange development occurred today:
Today (3 days after it stopping working) I randomly tried to switch the Wizard on and it indeed switched on. It showed that it had 0% battery. It didn't even show 0%, basically the battery charge graph was empty - no number, no fill, nothing.
While it was on charge the charge light was on (while it was 'broken' the charge light was off when I tried to charge). So I left it to charge and when I checked back in 15 minutes it was back to being 'dead'. Can't be started, no charge light, nada.
I don't really know what's going on, however I'm highly suspicious of the battery. Currently, I'm periodically trying to switch it on again so I can backup my data.
Any ideas what might be wrong with it, do you think it's the battery or is it more serious?
Regards,
The battery won't charge if it gets to low.
There is a thread about using a 9V battery to get the battery up to a level so it will charge. I don't have the link for it, try searching for it or maybe someone else will reply.
You might have a bad battery. I bought a new battery because I didn't think I was getting the life that I should. I tried using the old battery about a month after when I had to run out and my main was low. About 15 minuets later my phone started shutting of and rebooting. That was the end of that battery.
Yep, it's possible. If the battery is to empty, you can't charge the phone. It is stupid but it's just like that. You also can't power on the phone without a battery with the charger connected.
Yesterday I received my wizard and I had to revive my battery too because it was completely empty. I used a self made 5V power supply and after 2 minutes charging I placed the battery in the wizard and was able to charge and boot with the charger connected.
Here's the 9v battery trick, connect the + from the 9v battery to the + of the phones battery and the - to the -, hold there for only 10 seconds then remove the connection for 10 seconds and then repeat the process about 8 to 10 times and then put the battery back in the phone and connect it to the wall charger to fully charge.
Thanks for the advice. I'm going to do the jump-start thing.
However, I've hard time determining which is the - and which is the + pin layout on the battery, since the label is not correctly applied.
As far as I can see the - is the one at the far right, however I'm not sure which is the + pin.
Can someone help me with this, please?

When you take out the battery and put it back in that direction ,turn and face up the connector side fasing you,the first connector from the rightside of the battery is the ' + ' and the last is ' - ' towards the leftside.Be careful while connecting and try not to touch other connectors. Don't keep the connections longer then 10 seconds interval.
good luck
Xeno1,
My MDA battery also died and went below re-chargeable state. Your trick to use 9volt battery to jump-start it worked just fine for me. I connnected for about 20 seconds (2x times) and plugged it back into phone and connected USB cable to it and my nice yellow charging light came back on. After about 30 mins, I could use the phone.
THANKS FOR THE GREAT TIP!!!
easier fix, take a standard usb cable. rip off the smaller end with a wire cutter, expose the red and black wire. take out your battery, than connect the negative(black) wire to the negative end of the battery, than the red wire to the positive end of the battery, leave it in there for exactly 3-5 minutes for jump start. after that turn your wizard on, and quickly shove it inside a new usb cable. or the wall charger.
note:
if not done correctly, you may damage your wizard or the battery. if theres a power overload or your power goes out. your wizard will burn out!
feedback is greatly appreciated.
p.s after that my battery seem to be weak, charge barely holds for 12 hours. after 12-14 hours it will die out. so i suggest buying a new battery after couple of days.
Thanks guys! Vario died yesterday and wouldn't turn on or charge.
Tried the 9v battery recommended here and it worked! I was a little unsure which end was - and which was + but using the advise above, got it right. Wasn't too worried as found and ordered a replacement from ebay this morning for £7.
The first connector on the right hand side, nearest the end of the battery is the + the one more towards the middle and further away from its corresponding end is -, or at least, thats what worked for me.
Thanks again!
Experiencing the same issues after I set aside my Mini S as it was experiencing problems with regards to its screen alignment. Wasn't able to charge it during that time I kept in the drawer unused - due to frustration as I can't use it anymore. After downloading a guide to disassmble it so I could remedy the problem I found out that it won't power up anymore even with a new battery.
Well, haven't tried the jumpstart thing and the original battery was disposed of already to try the jumpstart idea. Could it be the internal battery is causing the problems? I opened my unit up and tested the internal battery for power and it registers a measly .2V left. Will use the 9V thing to power it up (as been doing that before on watch batteries that are hard to find replacements) before I do it on the main battery. Here's hoping it works as the Mini S has been quite useful for me until now.
UPDATE: I charged the internal battery and it now reads 1+ V and the external battery at 3+ V. No luck yet though as the unit still won't show any life. Any suggestions?
Vivanov, I know it's been a few years now, but did you end up fixing your problem? If so, how?
hey, i got the leo just over two weeks ago, and swapped my orange sim for my o2 sim (my phone is unlocked) yesterday night. This morning the phone did not charge at all and i still cannot get it to charge, i have tried via the wall plug and plugging into my PC. At the top of the phone there is a green LED flash and then an orange one.
Any ideas as to why it wont charge, im still under guarentee so if its any problems with the battery etc. i am sure i can get it replaced, Thanks in advance.
i've tried taking out the SIM then turned it on and off, that didn't work. I then tried the same but with the SanDisk card. Still no hope.
Hi, sorry to here about your troubles but it is nothing I haven't seen before. Hope this helps.

Try to release all the energy of the battery, then plug the usb cable to computer, us your PC to charge it.If it dosen't work, congrats then, you are in the same situation as me,
-order a new battery replacement see if it's sloved, if not, send it to HTC for repair.
btw, just curious, are you in Canada as well...?
hi i have the same problem solution is simple you just bend middle pin that connect battery bend it down a little and it should works
Thanks mmpl, I am gonna try that, I wish that may solve my battery drain problem as well.
nah im not Canadian, from the UK. The place i bought it from said i could send it to them and they can check it, if they can't fix it they'll send a new one to me
WOW! amazingly, i had no hope in it. But i did play around with the middle pin just a slight tap backwards and then *forced* the usb into my phone and computer, it switched on switched off i unplugged my phone is did a white screen flash, but it is now holding the solid orange LED of life! i can't understand what on earth was wrong, and it could still not charge but the LED seems to be correct!
Unfortunately i am now experiencing this with a replacement battery from China. It flashes green and orange when plugged in and won't charge. Original battery works normal. Well... back to seller.
Problem Fixed!
Thanks mmpl. The middle prong on the HD2 that connects the battery was pointing slightly up from horizontal (and it looks different than the two prongs and seems a little limp/loose); I pushed it down a little so it's just slightly down from horizontal; put the battery in and that fixed it! Thank you for posting the solution!!!
My symptoms were that the battery indicator icon in the title bar would switch to full bars when plugged in (did not show the plug icon in the title bar as it should have), but when I click on the battery indicator icon the sub screen (showing the battery) would show the actual state of the battery, e.g., 30% with one bar.
I've been also having freeze-up problems when dialing out, thereby requiring a re-boot (take the battery out or push the reset pin) once or twice every day (I'm on the phone a lot however), and maybe the daily removal/re-install of the battery weakened the prong.

Hi, I also have purchased a cheap replacement battery from China as a backup for my Samsung i500. I cannot charge this battery in the phone! I get a pop window when I connect my charging cable that states; "battery is not connected"! The stock original Samsung OEM battery charges in the phone just fine.
I wonder what the problem is?

Thanks mmpl, I had not even considered the pin until I read your post.
I know this is the wrong thread for xperia ray, but I just wanted to say that this is something that could happen to absolutely every phone. The middle pin on my ray was stuck in, so far in that it would not connect properly to the battery. By getting a sewing needle in and tinkering it back out it now connects and charges properly.
Also, I hear that if you have flashed your phone you may need to re-calibrate it. If your phone is rooted, you can do this with the aptly named app called BatteryCalibration. Worth considering I think.
Okay so I got my phone about a month ago, I had kept it stock for a week, went to a custom rom, and put it back to stock today.
Reasoning I went back to stock:
So I had been having an issue of not charging when I plug in the charger, the phone would recongized that it had been plugged in by bumping the battery meter to 100% instead of a charging icon. The LED light was blinking orange & green so I knew something wasn't right. I then proceeded to unplug the charger and saw that the 100% knocked down to 6% which it was at 8% when I plugged it in. After I saw that I removed the battery and tried a different battery ( brother has the same phone) and his was at 70% and I plugged in the charger and still the same thing happened.
So after this I have found out that it was the phone that had the issue as it was not charging the battery at all so I then returned to stock rom using my brothers battery and it still had the same issue.
I then saw the middle contact of the three golden contact on the back of the phone was sticking between the phone and the battery so I pulled out the battery and pushed the contact toward the phone and then I insert the battery back into the phone and then place the charger on it and then it started charging.
So now I need to confirm that this was the actual fix. Can anyone confirm that the middle contact is the actual one that charges the phone or was this just luck of the draw?
sorry for the long post but I thought this would be a big deal based on the design of the contacts aren't the best.

On most cell phone battery packs the center contact(s) are a data or temp sensor connection, the power is input during charging and drawn during use from the outer contacts.
It depends on how "smart" the battery pack is that determines exactly what those center contact(s) do. In sophisticated packs there is actually circuity inside the battery back that monitors voltage, current draw and temp on the battery to determine the battery's charge status and communicates this back to the phone over a serial data bus with those contacts. on simple battery packs the center contacts are simply connections to a thermistor to monitor the battery's temp during the charging cycle, so the phone can cut off charging power if the battery starts to overheat.
In the end, yes, if the phone cant get a connection to those center contacts, it likely will not initiate a charge cycle. Attempting to charge a lithium ion with no way to monitor it is just asking for fire or explosion
d0ug's point above is backed up by the fact that several users have had issues with charging and/or booting the HD2 when that one middle pin gets bent (which seems like a fairly common occurance in this phone).
Ok, so i have been having the same issue and couldnt find any information till now.
Custom rom or not, if the middle term gets bent it will not charge right, also if the battery gets warm to a certain point it will shut off on you. I have also noticed, if your battery is below 50% and your using it intensively it will also stop charging the battery. When the status gets bumped up to 100% the led's will flash between red and green, this usually means there is an issue between the battery being over save charging temp, or a malfunction of the data sensor circuit in the battery. This is built into the hardware of the phone and is a safety measure.
This is from HTC Tech support this morning.
If any one elst can find out anything, im sure there would be people glad to hear.
Too bad the terminal being bent is from having to pull out the battery all the time

I've never had to pull the battery when it freezes. I just hit the red reset button. Is that not working for people?

In my case, I just never have anything pointy enough to press the reset button, at least not as handy as just sliding the batt up and out by an inch or so. I think out of all the soft-resets I've done on my HD2, maybe 2 were by pushing the little button (yellow in my case)
hmm, i just checked my center pin, its still good. Like someone said above, i also reset my phone by just poping the battery out.
Also in the same situation that i usually don't have anything around to poke the reset button. I don't think ive ever actually used the reset button yet. All my previous WinMo phones had a stylus and the reset button was on the outside of the device, no battery cover removal, so the reset button was convenient to use. Battery removal seems like the simplest thing to do, if you're already removing the battery cover, just pop out the battery
How often are you guys having to reset your phones that way that you are damaging the pin, are you rocking the battery into it, or kind of just pushing it in? i noticed that the contacts seem to only fold down, they don't fold up or push in.
Ill definitely keep in mind now to put the battery in with a slightly downward motion to make sure the pins fold down, and don't get mashed in, which is where im guessing the bending is happening for you guys
My left pin got bent from all the battery pulls I've been doing. I think it happens when you don't slide it in at the right angle as d0ug has suggested. Now every time I do it, I make sure that all the pins are contacting correctly. If my left pin gets bent outward, the phone does not power up at all. (which made me freak out thinkin I broke it) Both stock and cooked ROMs have required battery pulls occasionally. Overall, I think I have to do battery pulls WAY WAY WAY more than I did with my previous MT3G. So far I have tried Kumars and Elegancia ROMs. I wish I could find a stable ROM that requires zero battery pulls. =T
yupp had the same problem with the connectors under the battery
I went in for a refurb and used it for a day and that pin was already bent so i went back in and this one seems to be in good working condition.
I think they should have done better job with the pins as I have never had these issues with any other phone.
WOW!! that fixed my problem.
*sniff* I love you guys! Thnx for the fix!
I'm trying out a couple of HD2s that an acquaintance had no business getting and is now looking to unload. The one is practically right out the box, the other looks like it has been around the DC loop a few times. I'm testing the well travelled one out when it looked like it needed charging, so I plug it in and start looking at the nice one. After 2hrs, I hear the tramp vibrate. When I go to see why it vibrated, it won't turn on again! It's after midnight, I haven't purchased it yet, haven't loaded a cooked ROM, haven't even run a stock update and it's already screwing up!?!? Since I had two I did some battery swaping then both went into boot loops. Many hours and a few gray hairs later, I got them both working again. I left them essentially alone until today. When the spouse went to sync the well-used of the HD2s, he noticed it needed charging. After almost an hour, he noticed that it had less charge than when he plugged it in. I noticed the charge light wasn't steady, it's flipping between red, green and nuttin'. My spouse, who had already laid claim to this HD2, did as he always does and jumped to the worst conclusion. I said make no inferences until we get home and check this forum. I knew you'd have the answer and you did not fail me! Best yet, it cost me nuttin' to fix!! Now do I point this out as a flaw for potentially lowering the sale price?
Thanks again!!
My take on this is that the flaw is in the way the battery wants to come out. When you lift using the tab on the left side, it tries to come out at an angle, angling from top left to bottom right, which means the connectors come away unevenly, and since the connector plates on the battery are inset, the plastic of the battery casing catches the pins as the battery rotates on its way up.
I keep my thumb on the battery just above the sim card until the battery is out about 45 degrees both top left and top right, and then pull it towards the top of the phone so the connectors all come away evenly, rather than being dragged up and over the pins.
Hi guys.
I bought a Nexus 4 from Ebay but ever since it arrived I've been having problems with the original battery (the battery would drop from 80% charge to 0, the phone would refuse to start up until i connected it to the charger, and cell signal would drop every now and then).
I just bought an original replacement battery, but after I installed it, the phone would not start, so i put it on charger and the white lightning would pop up and show that the battery is being charged.
The problem is - even after 10 hours at this state, the battery did not charge at all. The phone won't do anything without the charger connected at all, and when i hold the power button with the charger connected the phone just blinks red and restarts to the charging screen every time.
The phone is just acting the same as it is acting without any battery inserted at all.
So to clarify - new battery is not charging, I can get to bootloader mode and charging screen, and when i try to start up the device I get one quick blink from the red notif. light and quick restart back to the charging screen.
I'm having the new battery replaced on monday just in case I bought a faulty replacement battery, but do you have any tips in the meantime on how could I fix the issue?

If this continues to happen after replacing the battery again, the charging port must be fried.

See but the thing is, the phone charges the old battery just fine. I'm charging it right now as we speak.
Battery is probably copy/faulty, get a replacement.
Might not actually be a battery problem sounds more like the red light of death, which may have been caused by the battery changing but doesn't mean the battery is actually the problem. Plenty of threads around here on how to fix rlod

Well I thought so too, but I have tried literally everything except charging the battery with separate cables outside the phone and nothing helped. I actually think this can't be it, because I couldn't find a single thread about having RLOD after replacing battery on the internet. Anyway, I'll exchange the new battery for another new battery on monday and see if that helps or not.
So, I plugged my Nexus 4 into a generic car charger and it went black instantly. The battery was at about 92%. With the hope that a proper AC or computer USB charge connection would bring up the white battery icon and fix things, I stopped by an out of town T-mobile. The manager tried the button battery-reset (up volume + power for 60sec) and I googled alternatives and tried the - enter recovery by pressing those buttons for 15sec off the charger and connecting while still holding down the buttons - trick. Neither worked.
The manger seemed familiar with that and the other button pressing tricks, and said that really, my only real hope would be to reset/replace the battery, but that would void my warranty. However, although the T-mobile site claims my Google bought phone is under warranty (and I've been paying for it each month), technically, it isn't. Under them or Google (any more). So, I purchased the tools to open the phone, as well as a replacement battery. In the interim, I tried to use all the button combos and various charging connections to get it to come back to life. I *did* manage to get it charging the old battery. I know because the blinking red light turned constant for an hour or two, and the battery got warm. I can only guess that the battery was too damaged to keep the charge however, because I could never get it to turn on during or after. My best guess is that the software battery reset allowed the phone to send a charge to the battery - at least once.
After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

After getting my tools and replacement battery, I managed to get the phone open (with great effort - I think there must be a difference between batches there). I removed the old battery connection and looked to see if I could get the charge icon with it unattached and on the charger. I couldn't. Reconnecting the old battery didn't seem to make any difference.
I was about to go through the process of prying up the old battery when I realized that you can actually connect the new battery to the board connector without getting the old one out. So I did that. Leaving it charging like that for awhile didn't do anything, so I decided to do another software battery reset and I'm letting it sit on the charger overnight. All of this has been without reattaching the back.
So my major question is - does anyone know for sure if the phone actually charges the battery with the back off? I know there are important circuits there - which seem to shut down the phone after the battery or google image when not detected (at least that's my deducement after reading posts). But are those connections also used in charging? The Qi goes though the back to the charger function, so perhaps that connection has to be there? I would like to try and find out though beforehand. It took 2 hours and two mangled guitar picks to get it open the first time, and the second may be just as trying. (And believe me, towards the end, I was not concerned with being gentle.)
I am also curious about the four prong battery connection. I've seen the post about charging the battery using external sources by connecting to the two outer pins. Does that mean the two inner pins constitute a second circuit between the charged battery and the phone? And if I find another 3.8v battery fully charged, I could perhaps connect that to the phone instead by wires and get it booted into recovery? As to why I'd want to do that, I don't recall the last dated CM version I had installed, so finding that in their folder plus pulling off everything from /data... assuming I replaced this with another Nexus 4, I might be able to save myself a lot of setup hassle.
In terms of the red light... it actually seems to be an error code. When triggered, it blinks 7 times, and on the eighth stays lit for a bit before repeating.

I RAN INTO A SIMILAR PROBLEM
I found that holding the power button for a while allowed my nexus 4 running stock Lollipop 5.1 to boot back up.
Have considered that you may have a faulty USB port ?
Just pop the old battery out install the new one plug in the charger and it will charge. You can boot up without the back on. The back contains the antennia.... and the NFC circuit board.
Good luck

Well, still no luck. I ended up putting the new battery in and closing it up to try the Qi charger, but all I can get is either 7 or 10 red blinks followed by a short solid light. No white battery charging symbol or anything else.
When you say a faulty USB port, what are you referring to? The cable works (though I've also tried my Nexus 7 one too) and even though it won't boot, my computer does recognize that something is there when I plug my phone into it (it just can't figure out what's plugged in - which is normal). I want to say that it's trying and failing to charge the new battery. At this point, I think the charger messed up more than just the battery.
