Blinking Red Led Of Death. [Might Be Solved]

[bmx22c]

Hi, I just had this problem !
I forgot to plug it in last night and it was blinking red without display.
If I plug it via USB (no power brick, only USB port), it powers up but only display the battery indicator, displaying 0% all the time. Rebooting itself sometimes, displaying "50%" without charge, and then again 0%.
I tried to let it for an hour or so, without luck.
I could boot to TWRP, but it doesn't even recognize the battery at all.

And then I asked myself, well, let's try with the powerbrick !
Immediately after I plugged it in, it said 1% ! Then 4%, and I could boot !

PS: I tried "plug/unplug usb with power button in" without luck.

Hello, just a dumb idea... Have some of you trying to replace the battery ?? In another brand, a similar "game" was made whit me, the phone uses SD805 SoC and it was playing no boot. After I changed the buttery, the phone was good as new. I think this could be the same here.

I didn't try it, but i bet it would've worked.

I've had the same. Red light blinking when phone was connected to the charger - or even sometimes no led light at all.
Replacing the battery with new one helped.

I just had the red led blinking problem on my wife's Mi 5s.
Charging through the night didnt help, nor did changing the chargers or cables.
Battery had 3,9V so I knew the battery was OK.
The solution was to disconnect the battery and the cable, and to hold the power button for about 1-2 minutes. the I just connected the battery (not the cable) and clicked power button again, and I Mi logo appeared on screen, phone booted normally and battery was at 50%.

I almost bought a new phone after trying all the suggestions, but thankfully I decided to try one more and it worked, hope it helps someone

Nice to hear that you fixed your device!

From what i've found that this problem isn't related to a Single malfunction, The RED Blinking light could denote that the battery is discharged [So it needs charge] second this also have been related with the Power Section of the MOBO, simply i removed some of the short resistance and Capacitors and the mobo booted up and another one by replacing the battery, so far i've fixed 3 of these phones in the last 2 months and haven't seen the customer coming back for the same phone again instead he came for another one i asked him if the phone note 4 he had was working fine or not? He still have it and it's still working. So it's better to begin with the charging->then the battery replacement-> then the power section of the mobo which get ****ed up by overheating in extreme usage or using while charging. Hope this helps. And OP you're such a great Asshole.

Haha, thanks i guess. I have a new phone now (Mi A2) and no problems with it whats soo ever. Well except wifi, but that problem requires its own thread.

But thanks for letting us know more about this problem, not alot of information could be found about this issue. At least i couldn't find anything when this issue happened to me.

Sold the phone without display for 10€ ;D

Plug and unplug the phone repeatedly while holding the power button. That will get it charging again.

I think this solved my issue, after doing this trick for 10-12 times, my phone started to heat up(actually charged), 5 minutes later I pressed the power button and it booted up.

Thankyou!

The red light indicator comes up when battery level is critical. I suspect that the issue lays in the device trying to go in "the battery indicator mode". The battery voltage is too low to power the screen + internals combo, so it turns itself off or the device senses too low voltage to operate. It senses that the charger is connected, tries to light up, dies once again and stays stuck in this loop until the voltage is just about right. It's pretty much a russian roulette. To fix the issue as fast as possible, your charger needs to provide voltage greater than usual to make the device boot right away. My way of dealing with the issue is a short DIY USB cable to minimize the voltage drop (you should make it as short as you can) and a 2.1A Kingston adapter (the original adapter should work just fine though). After connecting with said cable to the adapter, the device boots in a matter of seconds. This solution works 100% of the time and I've had a couple of those with my redmi note 4x.
Keep it mind that this happens for a reason and you shouldn't allow your battery to fully discharge in order to get the most out of your battery's lifespan.

Weird chain of events for my red light blink event on my 2 year old Xiaomi Mi 5S Plus:
-On evening of 10.7. I updated my LineageOS to latest daily while charging the battery to 100%
-Started the next day with some 95% battery
-End of day I weirdly only have 32% left - Usually I have between 60-70%
-I charge to 100% using QC3.0 charger, it takes its normal time.
-Thinking the battery drain was due to some app - but there are none listed on the integrated battery control... I restart the phone while still plugged in.
-Phone boots and now shows 50% battery. Unplug + re-plug ... Now it's not charging at all. I restart the phone again.
-Phone does not boot!

-When I try turning it on, I just get a single blink of the red LED some seconds later.
-No button combination wakes it up.
-Holding the button down and unplug re-plug charging does not wake it up.
-Tried with different cables, QC3.0 charger, regular 5V 2.4A charger. Tried charging for hours. Same result.

-Opened the phone.
-Unplugged the battery.
-Connected the charging cable. Waited some minutes.
-Re-plugged the battery. Waited some minutes.
-Phone now boots with 80% battery. :silly:

Updated LineageOS to 13.07. and will keep an eye on it...

Just if anyone is facing this problem, it can be caused by a bad power IC chip. I had a mi5 with that problem. The solution is change the power IC chip, which cost like 2 dolars in aliexpress, but you will need special tools to change it. You can search videos in youtube. I couldn't find any store that did it, and I asked in like 7 or 8 stores. So I end up selling it for replacements...

Thanks nexxusty, it really did work.

I have Mi5s Plus and I had the same problem - turned off at 1%, I attempted to charge few hours later and just red light blinking with 0% battery symbol no matter how long I was "charging" it..
What I've done to fix it:
1) Open up the phone
2) Disconnected the battery and hold power button for approx. 30 seconds and connected it afterwards.
3) Got an iPad charger (5,2V and 2,4A), it has to be sth like this, I tried with 4 different ones, and Samsung Adaptive Charger - no luck. It should have voltage higher than 5V and amperage min. 2,4A.
4) Voilá! It started charging normally, after 10 minutes I had 8%

Y'all here may say that it is impossible to fix..WELL TAKE IT , i fixed ittttt!!!!! OHHHHHHHHH!!! All you have to do is to remove the battery and connect it to pc , and flash it woth miflash, thank me later...

Well ok, you might say WTF , why to trust you? Well if u don't trust me , try it on your own! See ya , thank me later :laugh:

Hi all, I have the same red blinking issue with my mi5s and this is happening for the second time. For the first time, I solved it by chance while I was trying the above solutions. But for now, there is no chance I tried every single way. By the way, my screen is also dead. When I plug the phone I have just red blinks. Now my question is, how can I just copy the data on the phone to my laptop? Is there any chance? But please remember the screen is also dead

Put a cable or a wore on the second wire inside the usb connection, and connect it to your pc

Help Please!

My device is at the same state, blinking red LED while in charge or when power button is pressed.
i did everything here was mentioned here. i removed battery and then connected it to PC, it shows 0% all the time no matter how much i wait. i could go to fastboot, so i went there and tried to flash stock recovery and TWRP recovery, neither was able to be flashed (error: Partition flashing is not allowed).
so i flashed fastboot rom and it was successfully flashed and restarted, but after restart, it just reboot non stop, without showing the 0% i previously talked about.i still can go to fastboot but now i cant even flash the same rom again!! neither recovery.

now if i connect the battery while it is in charge, phone shuts down immediately. as soon as i remove battery , phone wakes up and starts rebooting. before flashing rom, i could connect the battery while charging, but it did not charge.

So, what's happening?
