Force Shutdown with Power/Volume (or otherwise)

[Supra]

My Zenfone 9 has a broken screen, completely unresponsive. I can't figure out how to turn it off, Google is no help here. I've tried holding power for 30s and power and volume down (which just force reboots).

How can I make sure this device is turned off? My alarm keeps going off lmao

I think I had the same once and found advice to keep all buttons for 10-15 seconds. Power + Vol Up + Vol Down then phone restarted and everything worked well again. I hope this will help you.
