Question about NVIDIA Shield TV (2019)

Yes. Take out the batteries, saves a lot, I do the same 🤷♂️🤦♂️

For what reason do you switch off, what exactly is the problem?

That's how I did it now. But it would certainly not have been a problem if the signal deactivated after about 5 minutes of inactivity and reactivated after the first press of a button.
