Xiaomi 9 turning on/off

Hello,

My Xiaomi Note 9 turned on/off by itself for 5 hours and then won't turn on anymore.
I press the power button, the small white light at the top blinks but the screen doesn't.
Even after the volume up + power manipulation for 10 seconds.

Is this a common issue?

I had a similar problem with a Samsung S3, and it was due to the motherboard that had "burned out."

Thank you for your replies

Configuration: Android / Chrome 87.0.4280.101

Same problem, I thought it was because the memory is almost full, I manage to turn it on once in a hundred tries, I've deleted some apps but the problem persists, if you have managed to find out where the problem comes from, please share the solution with me.
Note that a few weeks ago the phone's sound, during calls, was faulty for over a month and then the sound came back on its own.
Is it a design flaw in the phone? Please share your experiences and especially the solutions you have found.
