If turning it off or leaving it in another room isn’t an option, you could let a podcast lull you to sleep.
I like to listen to The Unbelievable Truth for example. Relatively quiet, not demanding enough focus to keep you awake, but requires some attention so that if you’re doing something else on your phone you’re going miss what’s going on.
Usually takes me a couple of nights to get through one ~20min episode.
Return to office has made me quit.
