If you are turning it off, I would charge it, restart and turn it off for the test. Again, that is about making sure everything was "normal" at the start. And the point where the powered off screen is displayed is a little bit before the device finishes powering off. If there is a hung task, that could prevent the final power off, or delay it a lot longer than usual.
You can also turn on the developers mode and the power management logging options. That can show why the device is waking or not sleeping. I have used that to understand problems like this before.

Thanks for your reply.
The device was sleeping. I have fully charged it yesterday afternoon and after a power off - power on cycle I have put it in sleep mode.
the situation now, after around 24h is that the battery is 96% full. But as you said this is not linear and it happened also before that the first day after a full charge everything looked nominal. I'll see in the next 2-3 days.
Just a question: how can I turn on the developer mode?
Thanks!
