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?

Yes, this is the original battery. Aprx. 20 months old.
3. do you have a spare battery to try?

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?
4. do you have many applications, music etc. on the device?

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?
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, One thing you could try before given up on your battery. Try to Use your power connection to charge for while before starting up your device.
How much is a new battery?

When I connect the power cord the start up begins automatically.
There is a way to avoid the starting up?

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,
fanger
Guys pls help..I have this problem,that when I'm charging my trinity,it couldn't reach 100% of charging (full charge) instead was stuck to 70%.eventhough i charge it overnight.I'm thinking if it is a battery prob or the charger. i am using the originally supplied charger & battery.
Thanks in advance...
Have you tried powering the unit off, removing the battery for, say, 15 seconds, then refitting it and rebooting?... Check the battery level after reboot?... Then retry charging again?...
Maybe a full discharge might help "reset" the above problem too?...
I'm not sure, but I think the Trinity battery management is quite dependant on so called "coulomb counting" and I reckon sometimes it goes a bit wrong.

i tried all your suggestion bro,after rebooting,the battery meter increased 10%,tried to recharge,but still can't reach full.i tried to turn off my device then charge it,this time it goes upto 90%.it's a good sign but,charging while my phone is turned on is better right?i have no computer around,maybe i'll try to charge thru USB later..if it went ok,maybe i'll buy a new charger..thanx loopyloo for that sound advice..

Try battery callibration procedure!
The actual standalone charger (if that's what you're referring to) has no intelligence in it to speak of. Battery charge monitoring/status will be an integral function to the phone itself using dedicated h/w.
Something's not quite right with your kit somehow. Maybe the battery has gone a bit wrong (could be replaced - how much use has it had?)... Rather that than the phone itself, in which case it'll need repair.
You can try tnyynt's suggestion of Battery Calibration. Basically this requires you to totally discharge the battery (I suggest thru normal use of your phone!) then when it shuts down "cos battery is flat" reboot the phone into its bootloader screen (power down, then press and hold Power & Camera buttons until Tri-colour screen is displayed)... Then just leave the phone until it powers off of its own accord.
This may take a few hours (I did mine recently and it took @4hrs!) but the battery should be as discharged as its possible to get by that point...
And if you're lucky, it might just sort your problem out when you next recharge!
Good luck dude!!!

thanx again LoopyLoo,you made this procedure (battery callibration) clear to me,on how to do it.will try this procedure and will report asap the result.hope it works (fingers crossed),and hope it's not an internal phone prob.
Thanx Bro!!:>
Let me know how you get on.
I'm a little baffled as to why you have problems with your friends charge too but not USB???...
battery callibration not worked...
I'm sorry to report that after 3 times of trying the battery callibration method,my trinity still doesn't reach its 100% capacity of charging thru the standalone charger..but mysteriously charge a 100% with USB charging..I'm still not really sure why this happened..maybe will try to see a mobile technician for PPC..anyways,thanx for all your suggestion..will report ASAP after going to a service center..
Hello everyone my brother's Ph-1 keeps shutting down right after powering up, I have tried everything from factory resetting to trying a different charger, nothing seems to work. This happened after he didn't use the phone for almost a month, it worked perfectly before.
It powers off even when on charge or connected to the laptop.
The phone doesn't stay on for more than a minute or two which means i cannot use ADB to side load an update
The phone is running Android P and the April security update patch.
Please do help me out
Thanking you

It could be corrupted though it sounds a bit like a battery issue, to me. If battery discharges too much eg it didn't shut down itself properly when battery was at a low level (they retain more charge than shown to user so it can shut down with proper procedure) & the battery ran down past it's reserve the battery may not be able to be recharged with a normal charger even though you charge it. (Thought a battery specialist could possibly revive it with a boost charge, though I've only seen these used with industrial batteries)
with a "dead battery bootloop" sometimes you can get it going by booting when connected to the charger, but you'll probably need a new battery. Maybe also try boot into safe or recovery mode when connected to Essential charger. (I'm assuming your phone not corrupted, though as you haven't given us much info about exactly what happens & what you are seeing)

The phone shuts down even when in recovery or safe mode whilst connected to the charger.
It does sometimes fully boot up and then shutdowns, but mostly shuts down while still on the essential logo.
If I may ask what do you mean by the phone might be corrupt?
Can one month of non usage cause the battery to die out?

by corrupt I mean some data that is part of the boot process causes bootloop so it shuts down, but as your phone is shutting down at different points in boot cycle I think it's probably battery
Leaving the phone turned off unused for longish periods should not be a problem normally even with a few % left in battery. And even if left turned on it should shut itself down when battery low & be able to boot up again after a month due to the battery "reserve" capacity (but possibly a month was too long). And if it was not recharged straight away and/or rebooted multiple times the battery "reserve" could fall too low and not have enough power to start/shutdown properly (possibly causing data corruption ... though l don't know if there is some sort of fail-safe boot procedure ) Then there is a possibility there is a hardware fault with battery/phone that meant battery lost too much power.
There were some tricks ie "boost charge" you could do with removable batteries that were in "deep sleep" as shown here for example
https://m.youtube.com/watch?v=TEXA7qIJ968
But they don't really work without taking your battery out (for us we might as well get a new battery when opening phone up, & there would be some risk that you damage battery as we do not know the exact charge to apply on this battery, which could cause unsafe battery) I wouldn't want to freeze my phone even though it should survive OK, as I'd be alittle concerned about long term effect on our screens small pixels (I remember the guys at popular mechanics put an old flip phone with little LCD screen in liquid nitrogen & it still worked after being warmed up!).
See https://batteryuniversity.com/learn/article/low_voltage_cut_off
for more tech details
firmware issues do not cause the issue you are describing
you have a hardware problem
sounds like a bad battery to me
good news is the battery is not difficult to replace (don't listen to ifixit I am not sure what they where smoking when they did there tear down)
https://www.youtube.com/watch?v=BCKxAQXdTJ8
don't bother with silly and wrong tricks like trying to hack the battery back to life its the wrong way todo
if the battery ever gets to that point then the battery is bad enough said

So true! )) As much as I respect the guys from iFixit, they screwed this one up pretty badly - basically, made a tutorial on how to destroy your phone. Fixez.com did much better.
Hello people,
I have problem with my Samsung Edge 7 and please if you can just tell me what can be a problem and on which way should I go to solve this problem I would appreciate it very much. No need for step by step solution just tell me what can I do except send it to Samsung repair shop or recycle it. I will take it apart by myself if needed but I don't have a clue which part should I look to replace or what.
So... the problem is that I manage to charge the device one day when it don't want to charge and after that I managed to turn it on. Everything was working fine, didn't try anything much just unlock screen and put it to sleep.
After that I turned it off so it don't consume battery while I would be able to backup my data. When I was able to do backup I turned it on and it powered up normal so I proceed to backup my contacts (export to SD card).
When the export finishes phone just froze and I have to turn it off with POWER + VOLUME DOWN button combo.
After that few times when I try to power it on it just froze on boot up logo and I turned it off that few times with the same button combination as before. Until it don't want to power on anymore. So I tried to put it on charger to see if anything will happen, and nothing did.
I just left it to sit on my desk and I noticed that the phone is heating but I got no reaction at all from the phone (powering on or charging)
The day after when the battery was drained obviously I managed to charge it up again but when I power it on after it got to 100% charge it froze again and there goes same procedure as before (button combination restart, no response, heating, battery dead, charging...)
So now I can't even charge it anymore and I took out SD card to check if my contacts are there at least. But nothing, that contacts vcf file is not even saved on SD card even I choose that option when exporting my contacts.
Now I don't know what else to do since my phone wont even charge or power on and I would like to backup my data at least and then I can recycle it if I must.
So please if you have a clue just tell me where can I look at what can I try to do.
Thank you in advance and have a nice day
some of sgs has these problem. The motherboard is broke, i had same problem and sent to samsung service, they changed motherboard. I guess it's related to cpu temp sensor, inside the cpu.
Thank you Ganjax for your reply. That was the thing I was afraid of. So all my data goes away with motherboard?
I will wait few more days with some replies even I find your very useful and accurate since you had the same problem.
hey I also have the same issue, putting the phone in the freezer and letting it freeze makes it so that it can turn on for only 5minutes or till when it drops back to room temperature hopefully this will be enough to get your photos back.
millkyway4 thank you for you reply.
I am not in a possibility to try your method because I disassemble my phone and striped down battery for research purposes.
Neither I think that those 5 minutes will be enough to transfer all my data but if I ever reassemble my phone I will give it a shot.
So... Considering my research and striping down the battery the things goes like this (if someone is interested in this topic):
I disassemble the phone and remove the battery. Battery is connected on motherboard by some connector that I don't know the name or type, so if someone knows I would like to know too.
Since I couldn't find positive and negative lead on that connector (because of microscopic leads) little bit down on flat cable, near the battery, I removed coating and manage to find leads and measure voltage of the battery to confirm positive and negative lead.
By the measurements I assume that battery voltage is fine (~3.7V), but when I connect it to external charger which have built in ampere meter the battery doesn't charge as other batteries and ampere meter readings vary by 100mA +/- I set up to be initial charge. In normal case when I charge batteries amperes only goes down by the time the battery charges so I find this event an anomaly.
Since that is the case I removed the chip (from which the flat cable is coming out) that is on the battery assuming that it is causing that anomaly. Leaving the battery with only positive and negative lead that I connected and also measure and put on my external charger. But the same thing happens as with chip, or what is called, on the battery.
Going further with my research I cut down flat cable from battery chip (electronics) and connect positive and negative lead, I found before, directly on my charger on which I adjust voltage on ~3.75 volts and connect the connector with flat cable back to motherboard. So you probably see what I did here but if you don't the research I want to conduct is that my external charger acts as battery for the phone and I try to power it on like that.
In this case ampere meter shows 0 since the current which is flowing trough the phone is none. After I am sure that this is the case I tried to power on my phone with connected external charger like that and my ampere meter shown a current draw of 100-200mA on the POWER button pressed but the phone doesn't turn on.
So now I need someone with a little bit better knowledge of the phone, batteries, working order and type of connections like this to tell me what did I do right and wrong so I can prove that Ganjax statement, and my assumption, that motherboard is dead is really correct.
Ganjax don't mean I don't believe you or something, I appreciate your reply, this is just for research purposes because I would like to play with this stuff and that is the things that interest me.
And if there is some "fanatic" like that to tell me what can I do next and try or point out what should I do and don't make next please leave a comment and we can discuss this matter together and find out something about this case.
Thank you all and have a nice day
