MI 8 - shutdown problem

[Pezzo]

I have a problem with last ROM 8.7.12 v2 for my MI 8.
When I go to sleep, I shutdown the phone correctly with 100% of battery.
Next morning, for start the phone I have got to press and hold the power button. Phone reboot and normal start up but battery is 61%.
That was occurrend last 3 nights.
If I leave the phone up&running at night, next morning I don't have any battery drain.
Any idea?
Thank in advanced!

So when you power phone down, you have drain and when you leave it iddle/ sleep you don't?

Exactly!
Do you have any idea to solve it?

I only can say that probably the buttons work in other order. So power off goes to sleep and sleep make phone turn off... Did you try to power off and after a minute hit volume key and see if it awakes ?

Nothing. I shutdown the phone, wait 1 minutes, I hit volume key but it don't awakes. It seems off.
To turn on the phone I have got to press and hold the power button for more then 5 sec.
