Hello

I have a Redmi Note 11 smartphone. For the past few days, it has been turning off on its own. It tries to power back on by itself. I see the MI logo on the screen, then it turns off again, and so on.

I press and hold the power and volume buttons at the same time (I read that somewhere). Indeed, it restarts, but I'm not sure if it's really my action that does it.

What bothers me is that it's happening quite often now.
I would like to know the cause of this malfunction so I can fix the problem permanently.

Thank you

    Hello,

    Check if it remains operational when it's plugged in. It's possible that the battery, if it is 2 to 3 years old, needs to be replaced.

    To my knowledge, on Android, the power button and volume button combination allows you to take a screenshot.

    Hello,

    Thank you for your advice. Apparently, it doesn't come from the battery.

    Additionally, I received another suggestion from a different source. I was advised to remove the SIM card, clean it with a soft cloth, and put it back in. This was supposed to fix the problem.
    I did that, and I haven't had any issues since.

    I'm going to wait a few more days to make sure the problem is resolved, and I will come back here to mark it as resolved. This may help others who have the same issue.

    I confirm. The problem disappeared after cleaning the SIM card.
