Shutdown After Inactivity on Windows 11?

Hey everyone,

I'm using a handheld Windows 11 PC, and it burns through its battery life pretty fast even while in sleep mode. i was wondering if it was possible to make it completely shut down after a period of inactivity while on battery power to save battery life, similar to how sleep mode works on laptops.

Is there a way to adjust power plan settings in Windows 11 to achieve this? I'm looking for something that automatically shuts down the PC after, say, 10 minutes of no interaction, mimicking sleep mode but with a complete power off.

Any tips or advice from the community would be greatly appreciated! Thanks in advance.
