An other (un)usual problem with dead s7 edge - Samsung Galaxy S7 Edge Questions and Answers

Hi all,
So I'll start with backstory.
Is an 2 y/o S7 sm-g935f of my friends mother (which looks as new, not even 1 scratch), with initial problem that phone froze.
So first remedy was to reset it (vol - + pwr btn) but phone was unresponsive (which is weird), so she left it for a day to drain the battery afterwards plug into charger and working fine. At least for few days, then problem come back, and in matter of days started to freeze every time after 3 minutes of boot.
So I got it to me, and updated to latest fw from March/April 2019 (ending emc1 or smthing wise-like). 1st Flash successful, but froze on erasing/applying updates 25%, but reset it and it went trough, got AccuBattery app which was saying 84% battery life left, which isn't greatest but not bad. So after that I deleted all accounts on phone (used mine GA for playsotre) and flashed it again to have a clean start, after flash I watched it trough the process and it went flawlessly till "hello screen" at this point I turned off phone normally so she can set it up on her own. And from then (1 week later) phone won't turn no or charge at all, now I took back glass off (is not my first time doing it) and got 4.1V on battery which is a bit low to power it up, but it won't charge (before was charging normally), tried to unplug the battery to see if its in loop, but is just dead... Next step of mine will be to take battery out and charge it before replacing it (don't like wasting my/others money). If anybody got similar experience, I would like to hear from you.

Never had an issue with battery and my phone is 3 years old

So I took battery out, used my battery charger board to fully charge it, but it seem the battery doesn't work properly, so got ordered cheap knock off battery from ebay just for tests and waiting...

Sorted out, it was the PMIC (u7000) that failed. After researching a bit seems to be very common issue on this device. (Like iPhone signature failures). Sorted out by swapping motherboard (£35, is more money effective for friend/customer than £10 for ic + labour of 1-2 hours of micro-soldering).

Wizard situation: worse then a coma and maybe better than dead... But doesn't turn on

Hi there,
First I apologize about my poor English, I am Brazilian and should speak portuguese, but this is the best forum ever... so I'll try my English
My story:
Four days ago my 1,5 years old 9100 running the WM6 NTS was working perfectly, the best device I ever had. But, at night, I removed the battery to get the SIM card and then I put the battery back but did not turn on the phone. I used the SIM card in another phone during the night. I was afraid to lost it.
In the morning, I removed the battery again, put back the SIM card and then the battery. When I tried to turn it on, nothing happened, just like as if it was without any power. I was surprised, because I had fully charged the battery in the night before and before I first remove the battery, it was about 80% of power. So, I decided to try to recharge again, but there was no lights on. I left it charging for about 10 minutes and got nothing.
So, as I was leaving home, I put the 9100 in my pocket, after a few minutes I tried to turn it on again and it worked. The battery meter was showing about 80%.
Ok then… It worked well on Monday. But when I woke up yesterday morning (Tuesday), the phone seemed to have self-restarted during the night. So, I typed my password and it started working well again. I checked the battery meter and it was showing about 40% of charge. After a few minutes the phone seems to be totally dead. I tried to charge it again and after 2 hours I got nothing, it was still dead, did not turn on and there were no lights on.
Later on that day, I got a multi-meter and checked the battery tension. With the positive on my left I could check that measuring the power with the wires on the 1st “slot” and on the 3rd on, I get 3.47V. Measuring the 1st with the 4th I get 3.63V and measuring the 1st with the 5th or 6th I get 3.75V. Check what I mean at http://webtennis.rg3.com.br/qtek_9100/battery.gif.
I tried to remove the battery, then put it back and then turn it on again… It started, but in a few seconds, when was showing the OS, SPL, etc… it went off. I tried that again; it started, loaded the OS and went off. Once again I tried this, but with the power cable on, so it started but in seconds was off again.
So I thought “that might be a bug, maybe if I run the update utility it will work”. I started the phone in the bootloader mode, but before I connect the USB cable and start the RUU the 9100 went off. A few more times tring to remove the battery and starting it again, it went off and never came back again!!
I plugged the power cable on the wall and on the phone and there were no lights on, but I could feel the battery a bit warmer, just like it used to get. I left on the wall all night long and today in the morning still nothing. I removed the battery for about 30 minutes and got nothing, neither the screen with the OS, SPL, IPL…
Now I am despaired, don’t know what to do, no clues. I am in Brazil and don’t know where I can take to be repaired and have no plans to get back to Canada or Europe for the next 3 months.
Can you help me with this problem? I love my phone and want it working again.
Thanks for all your help.
Battery problem...?
It seems as thought you may be having a problem with your battery, not your phone. Try buying a battery off eBay, they are pretty cheap, and that should tell you what the problem actually is.
Or if you know anyone that has a wizard, try your battery in their device. If the problem is still appearing, then you will know that you just need a new battery.
Battery or charger ?
I agree with zakhir_n, it sounds like a battery issue not the phone. My friends MDA battery died after 2 months of use, so you can never be sure. We swapped batteries and revealed it was his battery not taking a charge.
Next check that you are using the original charger. I went away on business and grabbed the nearest charger for my 8125. Needless to say I grabbed a Motorola charger and it refused to charge the dead battery. Make sure you have the original charger, as it MUST say 1000ma or 1Amp output on the plug. The Motorola one I used was only 500ma or .5Amp and it was unable to recharge a dead 8125 (MDA) battery.
New status: WORKING
Hi there,
Thanks for all the posts.
Well, I checked my charger and it is a 1A 5V and my battery gets 100% of charge.
This is what I did:
Fully charged the battery, removed it for about 1 day an then I turned it on. Surprise!!! It was working and worked for 20 minutes and went off again e seemed to be dead.
Once more I the same thing but this time I flashed it with an official ROM. Fully charged the battery and removed for about 1 day. When I tried to turn it on, it worked as it was new.
So I flashed it with the WM6 Core 2.0n. It worked perfectly. When the battery got 80% of power, it restarted itself for several tines.
Now I bought a new battery and it is working very well, no problems till now. Guess you were right… I really had to change the battery.
Thanks for all the help and sorry about my English!!!
Regards,
Arthur
Nooooooooooooooooooooo
Hi there… Got the worst birthday present ever!!! Today I woke up and my QTek 9100 wasn’t working.
I got a new battery, when I put it on my phone it was 54% of charge. I used it till it gets 13%, then I fully charged it with my computer’s USB cable. Used the phone for 1 day and the battery was again around 80% of charge (just like the other time). I put it on “flight mode” went to sleep. When I woke up……. it was not working anymore, I put back the old battery and got nothing.
Now it is with the new battery being charged with my wall charger (1A 5V), but there is no lights on.
I already tried to run the WM5, tried a new WM6, checked the charger, replaced the battery and none of this seems to solve my problem… Do you know what more I could try? Do you know where I can send it to fix in Brazil?
I don’t know what to do… I already sent e-mails to QTek and to HTC and after 1 week got no answer…
Thanks for all the help!!!

Wizard suddenly died yesterday

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.

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?

Milestone 2 - Died..?

My girlfriend has a MS2, it is approx 5 weeks old.
It is as factory, she not interested in modding it.
Today, she took a call. Battery was at approx 60%, call lasted about 10min.
When she took the phone away from her ear, it powered off.
It has failed to restart.
We've left it connected to power for a few hours, we've left the battery out for a bit..
We've tried all the different versions of key presses + power on (camera+power, x+power, @+power, vol dn+power, etc, etc) but the phone simply does not respond to anything.
The only thing it will do is, the little light illuminates next to the micro-usb port when it's connected to power/pc.
Any suggestions as to what may have caused this?
Suggestions for a cure?
As stated, it is 5 weeks old, totally as it left the factory (unmodified/unmodded)
Not happy!
Don't like the idea of having to return it to HK (ebay vendor) for warranty, if it comes to that, think we'll get a refund and abandon Motorola. Pathetic.
TIA for any suggestions..
Did you try to remove battery for a while? That helped me in similar situation.
yes, we have tried that.. :-(
I had a similar problem last week! It really shocked me.
I connected the charger and left it connected. After about 5 hours it booted up again, but the battery was only at 5%.
After that I simply let it charge and finally the Milestone worked again. You might want to try another battery if it really doesn't charge or boot anymore.

It happened the same here. Just leaved it charging, when I least expected it booted up. Let it on the charger, if it doesn't fix, return to ebay.
Make sure you are using the wall socket charger. If my battery dies, USB won't charge the phone, at least not in a reasonable amount of time.
There might be a part on ur motherboard thats draining too much juice. I had the same problem on my phone though the battery depletion wasn't as significant as yours. Check with ur dealer and claim it from ur warranty. Its apparently a common problem with the milestone range
Sent from my MotoA953 using XDA App
Similar thing happened to mine one afternoon, after a quick play around I left it plugged into the charger for a few hrs and it eventually booted back up itself.

Phone died then came back to life

I wonder what the hell happened to my phone this morning, I thought it was dead. This morning at 4am, I pressed the home button, the clock and date were there as usual on the lockscreen. But there was no lockscreen, just a completely black background. I tried swiping it, nothing. Pressed the power button and the phone became completely dead, nothing happening, couldn't even get the time and date back. Connected to mains charger, nothing, no icon. Left it overnight till just now. Pressed power button, nothing. Connected to USB, nothing. Took battery cover off, removed sim card ready to put back in my old phone. Removed battery which was firmly in and then put battery back in after a few seconds. Everything fired up fine and it said 100% battery charge since obviously charging overnight.
Something up with the battery connection? It's not like the battery was loose in the compartment, it was slotted in as it should be as far as I could tell since I installed it when the phone was new 2 weeks ago. Yet removing the battery and putting it back seemed to cure the issue.
Seems it was a crash my phone experienced. Normal to have crashes or faulty phone? Only have launcher pro installed, no rooting, no drops, knocks or shocks to the phone.
Strange problem you had. I've had several crashes already, but all the ones that involved the phone itself crashing resulted in automatic reboots. I have a lot of stuff installed, but most of the time it's a game that'll crash it.
you could have solved this problem much earlier honestly.
in such cases it is very common to first take out the battery, wait a while and reinsert it. would have brought you the same solution in probably 10 minutes

Stock X727 stuck in bootloop

Stock .21 firmware. Never tried any other ROMs. Battery went down to 1% last night, charged it on stock charger to 30% then moved it to a different charger. An hour after that I got a call, I hanged up and about 1 hour later I heard the phone buzzing every 30 sec or so, I looked at it and realized it's in bootloop. If I press Vol- and Power I can get it in fastboot and with Vol+ and Power in Recovery. Can't figure out what to do from there though.
Update: Pressed -+ and left it the whole day in that mode. Came home, and it booted up and looked fine for about 3 minutes then it shut down by itself. It seems to me that there's some sort of memory/storage corruption. Any suggestions on how to proceed from here?
Phone booted normally and I was able to use it for about 12 hours. I was doing a Whatsapp backup this morning when it shut down and got into the bootloop again.

If you are using stock, immediately get rid of your usb c cable and buy a new one. There could be an issue with the cable that is causing problems with your battery.
Try to keep the charge percentage between 20% and 80%
Finally, your battery stats may be off. To resolve a battery stats issue you will need to reset the phone. Which again, if you are using stock and have never used a custom rom. You should definitely do a factory reset.
Same issue on 2 different chargers with 2 different cables that used to work well until now. None of the cables are stock. One of the chargers is stock, the other one aftermarket. My wife's S3 doesn't have any issues using the same cables and chargers. Issue seems to be happening when battery is full or almost full. Phone gets into a soft reset bootloop. I let it drain yesterday and was able to get in and do a factory reset. I then added my account and left it installing and updating apps overnight, while connected to the charger. Woke up with the phone off and after pressing power for 12 sec it got into the bootloop again. As you can imagine, it's impossible to keep the battery under 80%. Would it help if I try a custom rom? Maybe a new battery? I'm open to any suggestions as I really like this phone and can't find anything similar at a reasonable price.
So phone still reboots when battery is high. I can however get into Fastboot Mode and Tool All-In-One detects it. Tried to unlock the bootloader in the tool but it failed. I'm willing to try anything to get the phone back up and running but not sure where to start. Would really appreciate some guidance.
It really sounds like the battery is bad. You can buy a new battery for $8 .
If you replace the battery : Do NOT use a hairdryer to remove the screen. You will need a heat gun, they cost 7 dollars at harbor freight.
With a heat gun the lcd screen will practically fall off into your gloved hand.
I was going to offer to connect remotely and help with unlocking the bootloader and installing TWRP, Root and a Rom. But I sincerely believe that you need to get a new battery first.
