Let a Samsung A16 switch off automatically when the charger stops charging it (and viceversa!)

My Toyota's built-in navigator is a nightmare.

I'd dedicate, instead, a Samsung A16 with Android Auto + Google Maps to replace it.The cellphone would never do anything else and would normally be always left in the car.

Is there a way to have the cellphonte switching OFF automatically when I switch off the car (and the USB cable stops charging)? Scope: to prevent the cellphone getting totally discharged if I leave it alone on the car for days (having stupidly forgot to switch it off manually).

And (less likely) what about having the cellphone switch ON when I start the car motor (and the USB cable starts charging it)?

As in the old days with a Tom Tom!
