Switch off in sleep

Hi
Every night my device switches off itself.
During the day , no problem.
Any idea about this issue ( firmware 4.5.2.7 A ) ?

Go into settings and the accessibility (pointing hand) and turn off scheduled power on and off.

Ok I 'm going to see if the issue is resolved

Many thx kami.
It’s the first time I see this option on android…I don’t know.
It’s OK now.
