Hello XDA,
Yes, I know you've seen questions like these before but hear me out; I've tried practically everything I could and wanted to know if there was anything else before I go to a service centre.
Situation: One day, randomly, my phone decides to start discharging its battery as fast as it can. That night I turned off my phone at ~30% and the next morning it didn't turn on at all. i.e. battery was draining while the phone was off. The next night I tried removing the battery while sleeping. It was about ~40% when I turned it off. Next morning I turn on the phone and whoa the battery is 50%.
This happens even when my GPRS/EDGE is turned off, the sync is turned off and no apps have been installed.
What I did: (Apart from going to the SE service centre, of course). I tried doing a battery recalibration.
1. Drained it fully. Charged it. Turned off and charged it to full 100%. Removed batterystats.bin. Nothing happened.
2. Drained it fully. Charged it. Drained again. Charged it for 8+ hours while turned off. I still don't know if this has had any effect.
3. Did a complete factory reset. No effect.
4. Repaired the phone using SE repair. No effect.
Does anybody have any other idea?
Oh I don't have any idea but to say good luck and sorry for your trouble and I hope that doesn't happen to my xperia.
if you've exhausted all possible troubleshooting, then, bring it to an SE service center .. you might also want to buy an extra battery along the way ..
download Android System Info from the market and check your running apps/tasks...
should give you insight to which app/s might be gobbling up resources...
that is, if you haven't tried doing that yet...
I have the same problem a months back. Do you by any chance use a portable charger? Portable charger can screw up phones like that. If not, then it must be faulty charger. But the bad news is that it probably hardware. If you are lucky, it's the battery, you can get a replacement for a week from SE or you can just buy a new one ( I recomend the the original SE branded). Or if you are unlucky, it's the whole hardware, which mean you have to turn it in to SE, wait 3 days only to be told that it will took them a month to repair it. Either way, you should get your phone to the service center ASAP.

Man that sucks. Will have to take it to the service centre on Monday, then
It's usually an app, that dosn't terminate properly. You can see it in Battery history, when the phone does not seem to go back to sleep mode. The app is usually the one on top in 'partial awaikening mode' (translation from german) and keeps the phone in this mode, what drains the battery.
Happens here from time to time. The default music player from SE does it almost everytime. Last time for me it was netcounter.
Either killing this app or reboot fixes the problem.
Hope that helps...
I came across a bricked vibrant online and the guy said he'd swap my old phone with it for free.
He told me the phone was bricked because while he was rooting it, the computer died, and he doesn't have a computer anymore to fix it himself.
He told me the phone's battery is dead & that since it's in download mode, the battery can't be charged and you need a computer to do so. He said it should be an easy fix, but might require a DIY jig, but from his experience he hasn't come across a Vibrant that's needed a jig.
I said I can bring my laptop, and plug the phone in to see if it works.
He said it can take up to an hour for the phone to come on.
Is he making stuff up, and hiding the fact the screen is dead, or the phone is broken? Or is this all true?
When the battery dies, phone kicks out of download mode naturally.
When you plug in on a pc if phone is not recognized then you have a brick and you need jtagging to get fixed.
If your phone is old and you can find a jtag fixer for logical amount of money i would go for it, but before check for any water damage just to be sure.
I can tell you that Vibrants are very hard to brick. I dont know the nature of the deal (trade phones) but I would flash it with Odin first and if it works then take the phone. If they guy wants it back then charge him $50 for repair fee.
So him saying that the phone's dead battery might need an hour to turn on isn't true?
the story doesn't seem that far off.. i dunno. afaik charging the battery doesn't have anything to do with it being on download mode or not before/while/after it died but w/e.
My SGS2 died on me yesterday. was working all day as usual but at the afternoon when i where to make a call it wouldn't wake. Had 50% or more left on the bats for sure at the moment.
The phone where running the CM9 development rom wich has been running on it since beginning of january Last time i updated it was about a week ago. (Don't think this problem is related to the rom though)
Symptoms:
The phone is totaly dead, no signs of life on the screen. Cannot get in to download or do normal boot.
When I charge nothing happens on the screen, but after a little while the phone begins to get hot betwheen the camera and the battery (where the simcard is)
This video is not mine, but our phone seems to have the exact same symptoms.
I have tried:
Re-attaching the battery, and leaving it whitout bat for a few hours
Starting it with charger in with and whitout a battery
Tried a bettery of a friends SGS2
Pluging it to the computer, no sign of life (my computer does not react at all)
Nothing works
My thought is that this is a hardware related issue. But please correct me if I am wrong.
I haven't tried a JIG yet, will see if I have correct resistors at work tomorrow and make one. But i hardly believe it will work.
Is there any chance the JIG can reset the counter even if I wont get any life from it? or is it first after the flash to stock with JTAG the counter resets?

You're confusing JTAG with USB jig, but it's extremely unlikely to do anything. Considering the phone isn't responding to anything anyway, I also doubt the custom binary counter matters much.

Yeah you ar right, i was confusing them. But I'll try if I have the materials. And if no one else have any good advice for a fix I'll just send in the phone to Samsung tomorrow.
Thanks for your reply
mine doing the same but after a failed flash with odin

So I figure this is a hard brick tried everything u did and a jig gonna send it to Mobiletech videos for jtag fix after i get paid and hope that works.
any news?
My phone did the same last night.
cm9..
Totally dead, cannot charge. Please any advice would be great. thanks.
You could try a jig, but as per the above unlikely to work. Needs to be JTAG'd/repaired either by Samsung or a 3rd party repairer. Hopefully if you send it to Samsung they won't be able to tell the phone has had non-stock firmware on it as per Oinky's post & fix it under warranty (they may not tho).
This is going to sound odd but check you're display.
Wipe it clean and hold it at an angle against a bright lamp. Look for any small cracks or black lines.
Could the phone be water damaged?
The backup battery on the motherboard also can leak and cause problems like this
I work on the Samsung team at a service center in Norway and these are some common reasons for a dead phone like this
Could maybe be the battery on the motherboard that has leaked, but i guess i won't find out until it comes back from service.
Strange though.. Phone has been fine, just all of a sudden this. Exactly as the op describes..
I put it on the charger last night, had around 20% battery left. In the morning it was completely dead, and a bit hot. Plugged in the charger again, and the charging symbol comes up for a few seconds, disappears, comes back etc a few times, then it gets rather hot around the camera, and on the front side (screen side) and stays completely dead (no charging symbol), until it has been unplugged and let to cool down a bit.
Every time i plug it in, the same thing happens.
I'm traveling, and wont be able to send it on service until after a month's time.
alas, phone free holiday
Walking out of work yesterday, I swapped my dying battery for my freshly charged one, and powered up the phone. I see the Samsung logo pop up, and then the CyanogenMod wheel start spinning, so I slip it in my pocket. I pull it out a couple of minutes later to check something, and the screen is black. I press the power button a few more times, and the Samsung logo shows up again. Apparently my phone was off. So I wait on it to boot up, but it never leaves the Samsung logo. It sits, and sits, and sits...for a good 30-45 seconds, it sits on that screen. And then it goes black. I try again, but nothing happens. I switch back to the dying-but-not-dead battery, still nothing. I leave it to sit on the seat of the car with no battery for the drive home, and try again. Nothing. I leave it to sit on the charger for a couple of hours, both with and without a battery. Nothing. I leave it "charging" overnight. It's warm in the morning, but still nothing. I can pull the battery and put it back in, hit the button, and a little while later it will heat up, as if it's running and something's hitting the CPU...but no vibrations from the phone, no sounds, no anything at all, other than the heat. I tried my jig just now, as it was in my desk at work. More nothing. The phone is cold, the battery is cold, it might as well be a rock.
So...any chance of saving this thing? I'm really hoping to hold out for Black Friday sales to replace it with an S4 or something. If I can get this thing to last me another two months, I'll be happy. If it goes belly up November 30, that's fine. I just hope I can make it last until then. I already had to throw down $50 to get my wife a limp-along phone off Craigslist...am I going to be stuck doing the same for me?
First see if you can boot into recovery and perform a wipe data/factory reset. If not, see if you can get into download mode. If you can, flash back to stock and see if that lets it boot. In any event, you should perform a wipe data/factory reset at the earliest possible moment, even if you have to reflash the firmware first. If you can get back to stock, you should be able to reinstall your custom firmware.
So far I can't convince it to acknowledge that it's even on. The only sign it's not 100% dead is that it warms up when plugged in. I have no idea if it's actually doing anything other than sending juice to the battery because there's nothing on the screen and no vibrations or sound to alert me that it's doing anything at all.
:-/
I'll add that my computer doesn't acknowledge the phone's existence. Linux desktop, lsusb shows nothing remotely Android/Samsung related. Granted, a failing microUSB port on the phone isn't helping, so I don't know how valid this particular test is.
So u are in the need to enter the fast boot mode or else try the official firmware installation by the help of SD card.....
Hit thanks if this helped you...

...could you explain either of those? Fastboot, from what I can tell, is an HTC thing, and has nothing to do with Samsung phones in general nor the i777 in particular. As for firmware installation, is there a way to do this without any screen, PC connection, or feedback from the phone whatsoever?

Some Samsung phones have fast boot. I think the S4 does. The I777 does not.
If you can get the phone into download mode, (and if your usb connection is working, which I think from what you said may be in question,) then you can use the Samsung tool, Odin3, to flash firmware. You would have to use a Windows computer since Odin does not work on Linux.
I think your main problem is that you have a failing USB port. You should consider buying a replacement and putting it in yourself. It is supposed to be fairly easy. Once you have that working, you should be able to recover your phone.
Could it be possible that whatever it was trying to run drained the battery and now it's just refusing to charge? I had almost an exact same situation happen to me. I ended up having to buy a cheapo external battery charger from amazon to charge the battery and finally get it to boot.

Sadly, download mode doesn't seem likely. The phone is basically functionally a rock, with the limitation that it's probably easier to break than a rock. I may venture down the replacement USB road, although I'm a bit leery of spending money on the device, given that it won't even power on.

That's what I initially suspected, but I actually have a Samsung charger I bought off Amazon that came with a spare battery, and I've charged both batteries with it to full capacity. What does appear to be happening is that when it's generating heat, it's actually discharging the battery rather than charging, as a battery pulled from the phone takes much longer to charge on the external charger than one that has been charged from the charger, pulled, let sit, and put back in the charger. It's possible the phone refuses to power on until it can charge, though, because I too have had that issue in the past, and the only solution was to let it sit on the charger for a few hours. The first half-hour or so, nothing happened, but then eventually I'd get the battery charge animation. Sadly, letting the phone sit overnight did nothing this time around.

Dear all,
I hope there is someone here, who can help me with my issue. I lost my hope after trying almost everything found in the internet.
So here is the problem: I was using my phone as a navigation in my car. The battery was low, so I used the car charger and kept it plugged, while driving. I observed, that even though I was charging my phone via car charger, the battery continued to get low and finally the phone turned off. After reaching home, I plugged my phone with an original quick charger from Xiaomi. Unfortunately I was not able to charge my phone and it got stuck in a bootloop, with a phone showing Mi Logo, vibrating and switching off repeatedly.
When I connect the phone with the laptop, it is shortly recognized (when it is booting) and then disconnected and again and again. I can go to fastboot mode but I cannot flash my phone using MiFlash, because I get an error: Failed. Low battery.
Does anyone know the solution? I would really appreciate any help.

Are you on miui or a custom rom?
I think I know what problem you are facing, your device's battery is actually drained of all the power, like it empty. So drained that it doesn't even have the energy to turn on the phone to get power. I had a lenovo a560 last year, and it had the same problem, so what i had to do was either leave it for charging and pray that it begins charging (and sometimes after 3 or 4 hours the battery started charging as normal when it got 1% battery), or the second method was that i took the removable battery out and charged it externally using wires. The second method worked since the battery got enough power, to keep the phone on during charging.
Now the problem is that redmi note 4 doesn't have a removable battery, so either you can leave the phone for charging, and actually forget about it for a day, or the only other thing is that you have to visit a service center.
Not joking about the charging process but that is the only thing you can do.

But wait, if the phone is able to stay in fastboot mode, why not charge it there? Like just open fastboot mode, and connect the charger. It will atleast charge some percent.

Hi, i thought about it before, but the phone was staying in fastboot mode for a very short time, to short to charge any resonable amount of power, and kept rebooting quickly. I left the phone for two days without trying to fix it and I tried just now to go into fastboot and try to charge. It stays now for quite a time in fastboot so I will keep my fingers crossed that I will be able to charge. I will update here if it was a success or not. Meanwhile, thank you for all your ideas! Lets see what happens...

Unfortunately, no good results. I kept my phone in fastboot mode multiple times, but I was not able to charge my phone. Turning off fastboot is only causing phone to stuck in bootloop.
I also had an impression, that the phone was not warm at the back, where the battery is. Now I am starting to think that the battery is completely dead and I have to change it. But how is it even possible, that after 8 MONTHS the battery is completely f***ed up?
Can I somehow check the state of the battery? I would like to be sure, that there is no way to bring the battery back to life and I really have to go somewhere to change it. I am really reluctant to have a battery from some unknown company. :crying:

Are you rooted?
This is really a kernel fault man, I had the same issues with mediatek Chipsets before, but you are saying in "8 months", so that means you are well covered in warranty. You can send an e-mail to Xiaomi customer care or visit a service centre with the phone bill. I am pretty sure a faulty battery or such happening can be covered using warranty, plus I would suggest NOT to get the battery changed from a 3rd party store.

Sorry, I actually don't know much about the phones, so I don't know what 'rooted' means. I never did anything with my phone, software or whatever more than required.
With the warranty there is a different problem in my case: I bought my phone in China when I was there for my business trip and I live in Europe (yeah I know, my own fault, I should have bought it at home). I have bill and everything but I guess it will not help. Besides, Xiaomi gives 6 months warranty for battery (in case this is really the battery).

Knowing that you are not rooted is a positive thing when regarding the warranty, ok so here is the thing which you should do. But first of all please stop the battery charging process, since this can now be harmful and can damage the components. Ok so here's what you should do -
[email protected]
Send an email to that address regarding the battery problem. And provide the details including about the drainage of battery, and the methods which you tried. Plus attach the bill also. It doesn't really matter where you bought it, because the bill serves as to give them information that the device you own is actually bought by you, and it contains details about device like IMEI etc. If they respond and say that you can send your device to them, (in this case they will give you an address) you should do that. If they say they cannot help it, then consider getting a repair from a local shop.
I just checked my phone's inside and found out that you cannot externally charge the battery, so this means you need a repair, unfortunately.
Before ending this reply I just wanna clear the fact that,
The battery isn't damaged, it just isn't able to get power,(here it is because of the device) this means that if somehow some energy can be provided to the battery, the battery need not be replaced.
I wish you luck , may you be able to fix your phone again.

I am still waiting for the response from Global Service. If nothing happens, I will go to local 'mi center', where I know they can repair xiaomi phones, but not on warranty.
Apart from that, phone is still dead, but I have not tried yet anything else. I found this: https://xiaomifirmware.com/guides-and-tips/fix-bootloop-redmi-note-4-mtk/
But I am not sure, if this should work. Anyone have tried?

I did not try anything from this yet, I have my phone at home, but maybe it will help some of you.
btw. the previous method from the link (deep flash mode) is not working for me.
PEOPLE I FIXED MY PHONE!!! I used again and again this method, which I have already posted before: https://xiaomifirmware.com/guides-and-tips/fix-bootloop-redmi-note-4-mtk/
I didn't work at the beginning, so I left my phone and actually wanted to wait till I go back home to my country for the weekend and visit Xiaomi service, but FINALLY IT WORKED!!! I cannot explained what was the reason that this time it clicked. My phone was completely drained, left for long time without touching. As a result I have a battery icon now and it is charging, no bootloop anymore. Hope this method would help someone. Be patient and try multiple times!
So it is not software problem causing the bootloop
So it is not a software, but only hardware - the battery - as the only problem in this case. I am facing a very similar case with my Redmi Note 4x Mediatek (4/64 Memory) just starting Friday morning (9Feb). I thought it was charging overnight, but in the morning found the power totally drained, and stucked not be able to recharge for hours. This phone is still under warranty (9month use) but ridiculously the Official Service Agent said they need up to 40days to fix this phone. This is worst experience comparing to other phones I ever had.
