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...
One day when the battery went down i put my phone on charging, after some time came an error msg popup..
' your battery temperature is getting high force shutdown'
when i switched of my phone and rebooted it doesn't boot..
now the phone is dead..
guess the battery maybe drained. dont hav any alternate battery.. tried another charger , no luck..
tried pressing vol up key+home+power, no luck..
while connected to charger, phone heats up near the camera, under the sim slot.. (heats up even when connected without battery)
on warranty period, going for the service center.. is there anything else i can do?
If you have warranty I would just go that route. Even if you can bring it back to life it may have caused some damage to the internals and would probably crap out again.

yes im worried abt the internals, it heats up like an oven, seems lyk the boardn is shorted inside somewhr.. im goin for the warranty, but it would take time i guess..
did anyone else hav the same problem?
Mine also heats up near the camera a fkin lot..
LG L9 P765
If im replying you..then be a good bytch.....
Got my mainboard replaced from Lg service center.. got it workin, but now i hav noise and disturbance during call...
LG Optimus L9 P760 can of course overheat itself then force shutdown.
Instructions:
1. Wait until your device cools down completely.
2. Plug charger in. In case your battery was entirely empty, after plugging the charger in, your screen may not respond for a while. It's because your device hasn't got enough voltage to turn screen on. Only thing you need to do is start charging your phone and even if it doesn't seem like it's being charged, leave it that way. After 10-15 minutes press home button to see if screen is back alive. If yes, you're fine. If not, take it to service.
I hope this helps.
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?

That post shows you how to enter deep flash mode. You can give it a try. If that works, Voila, If it does't better go the service center.
So I got the response from service (it took them ages). Maybe it will help someone:
With respect to your concern, I would request you to please follow some troubleshooting steps in order to resolve your issue:
Try to charge your device with another compatible charger for at least 30 minutes
Long press power button for 10-15 seconds and check whether the device is responding or not
If the issue persists please follow the below mentioned steps:
Note: The below mentioned procedure deletes the data you have on your phone.
Sign Out from your Mi Account :-
Go to the settings
Select Mi Account
Confirm to Sign out
Create a backup : -
Go to the settings
Go to the additional settings
Go to the backup and reset
Go to the local backup
Go to the backup
Select system and apps
Then, select backup so that a backup would be created
After creating the backup, you can find your backup file through the below mentioned steps:
Go to the "explorer"
Select "storage" option
Then, "MIUI"
You will get a "backup" option
Select "all backup"
In this folder, you will be able to see your "backup file"
(Note :- Please save the backup file on your PC/Laptop so that your important data would be prevented)
Factory data reset :-
Go to the settings
Go to the additional settings
Go to the backup and reset
Tap on factory data reset
In order to restore your backup file, please follow the below mentioned steps:
Go to the settings
Go to the additional settings
Go to the backup and reset
Go to the local backup
After that, select your "backup file"
Then, "restore" it
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.
Last Friday (24.09.2021) I changed my phone's battery. I cleaned my phone, somehow some alchool entered in the charging port then I plugged it in like an idiot. Luckly nothing else broke except the charging port so I ordered a new one. The phone was working fine at the time and I could have used it normally, just no charging.
Today I finally got it, switched it, tried to turn it on and it wasn't turning on. I put it to charge, expecting my battery to be just empty, and I see the red LED blinking and the screen wasn't turning on at all. At first I thought that it was just a faulty battery and I tried my old one, same results. I had an old P9 lite lying around so I decided to test my battery and it worked.
I'm worried that somehow I broke it even further and I won't be able to retrive my photos and important files back. Is there any way to fix it?

I think the only way to save your data is to extract the data from the emmc module and install it on a new motherboard (maybe I'm wrong, I'm not an expert). Ask the service center. But complete motherboard replacement is too expensive if you don't have a phone warranty...

Hi. It might be very very late, it's been one year since you posted this. But the exact same thing happened to me. Turns out you simply just need to force enter recovery, charge it a bit, maybe 5 minutes or so, then reboot.
Here's how I did that:
Back cover open.
Unplug battery.
[Be careful of static electricity]
Plug charger. The phone turns on.
Wait until it enters recovery mode.
Plug battery. Yes, in the phone on, recovery mode state.
Wait around 5 minutes.
Reboot.
If you can enter the main screen, wait a bit to see whether the battery is charging or not (the percentage goes up). If it's charging, then you can put everything back again.
If the phone stays dead when you plugged it with the battery unplugged, then maybe it's another hardware issue..

Thanks for replying, but unfortunately the problem still remains even after trying that. The furthest I could get is into recovery mode.
Bought a new phone a long time ago anyways, so it's no longer needed.
