an app feature can will automatically restart or shutdown my samsung galaxy s6 without rooting?

[AC Question]

I need an application or feature for my Samsung galaxy s6 that when put on a timer will shut down or restart my device. It will save a lot of battery when i am asleep and at work so i dont have to manually power it off and on.

All applications on Google playstore require root and this is dangerous as it violates the warranty.

Can Samsung create this feature please or is there an app ?
