Redmi note 8 power button error - Redmi Note Q&A, Help & Troubleshooting

So, few weeks ago my phone was suddenly turned off and stuck in boot mode ( Redmi logo and reset again ) for almost an hour. I thought it just a random error because overheat etc. so im not really care about it because it fixed by itself.
Yesterday, i got that error again for 6 hours and at some moment i can successfully boot the phone. When i try to touch the power button, the power button suddenly keep pressing itself until sometimes the phone reboot again. Is that normal to get that kind of error? is it just a random error or is there anything i can do to fix the problem? thanks

Boot Logo Repeating

I have a galaxy s4 (i9500) and got it in used condition, a year ago. Never suspected a single problem in it.
Today I powered off my mobile for charging then after 25 minutes I took it off. I held the power button then I saw my boot logo(Where there is written Samsung Galaxy S4 GT-i9500). That logo kept showing as usual for 2 seconds and screen went black and again that logo appeared for 2 seconds and screen gone black and again it appeared, so, I'm stuck in kinda loop not a bootlooop exactly(maybe because bootloop refers to being stuck on boot screen while in my case its boot logo). I then removed the battery and inserted it back after an hour and as soon as I inserted it back the mobile itself turned on as if I held power button but this time again I was stuck in that loop. Moreover when I tried going into download mode, I didn't even need to hold the power button along with the volume down and home, it itself proceeded to confirmation screen of odin mode. And after that confirmation screen appeared saying that whether I really want to boot into download mode, disappeared itself after like 3 or 4 seconds even though I didn't press any key. And in case I press vol up key confirming to boot to download mode, then it again takes me to that loop. I'm too much confused . I can't even flash the firmware as it won;t boot to download mode neither am I able to boot into recovery.
Now do u really think the problem might be the power button(Which is maybe stuck in the state of pressed).
Or else it can be the battery coz my battery is also just average not too good?
I also inserted the command( in build.prop file) for enabling nav. bar and the code was correct but I never rebooted after inserting that. this was the first time I rebooted after that.
SOrry for some bad English.
Do you have something like this? I'm now having problem with getting my phone back to work...

From what you say it seams like power button problem, try to start the phone and connect it to the charger. When it start take out the battery, it will be powered by charger and you will eliminate battery problem.

Poco m3 turned off during an update

I am sorry if this is a dumb thread I am just worried. I was watching my Poco M3 update up to 60%(my battery was on 68% before starting the update) then I started to watch TV and didn't pay much attention to the phone. When I looked at it it was off and i thought that maybe it is just in the process of rebooting or its already on the lock screen .Because I thought it may still be rebooting I just placed my finger on the fingerprint reader because I didn't want to risk turning it of by pressing the power button. My phone didn't respond at all. I haven't tried to hold the power button because I'm worried that its still in the process of updating. What should I do ?
Never mind. I had to hold the power button for 10 seconds and it turned on. I am sorry for wasting your time. I was so worried since it was a new phone and I couldn't afford a new one. I am sorry again.
This post was usefull, it happened to me too. The phone wouldn't even show an image when connected to a charger. I waited for a while, entered Fastboot succesfully and then, after the second (on the first one remained stuck on the MIUI screen) 10s power button push, it succesfully booted
It happened also to me during update to 12.0.8.0, but I used Power and Vol+ and then Reboot to System.
It was a moment of anxiety.
It happened to me to. It is a branch new phone and I got so worried that I might just have bricked it. Fk Xaomi.
just happended with me right its on MIUI Screen hope its get on
Update: Just Booted In Fastboot Its on Screen now
Same thing just happened to me too. My phone is not turning on at all. I tried holding the power button for 10 seconds as discussed here, tried fast booting, tried connecting charger and starting. Nothing is working. Going into panic mode.
**UPDATE***
After leaving the phone alone for 24 hours in which time it was completely unresponsive to anything I tried, I connected the charger and just pressed power button and it decided to just start normally. POCO needs to address this situation.
**UPDATE***
Phone is not responding again after restrating. I give up on this phone.

SOLVED Post update infinite bootloop, restarts before fastboot menu

Hi guys,
one day after some minor update (don't know if it's related) my Redmi 9 Pro started restarting while on the table. I was able to open fastboot, could scroll between options via volume buttons, but couldn't confirm anything with power button. It kept restarting every cca 6 seconds.
After several hours of restarting the battery died.
When I plugged the charger, the phone started restarting again. But now, I cannot even acces fastboot. It restarts before the menu appears.
I didn't do anything with the phone, only updated official actualizations. I have no warranty anymore, its 2 and a half year old.
Any ideas? Thank you!
SOLUTION: After a few hours of googling I found a tip to push power button 10+ when mi logo shows up. It helped.
