"HUGE battery loss when turned off: When I go to bed at night, I turn my phone off. By off I mean complete shut down. I notice that when I power back on in the morning, I lose as much as 30% battery life. Is this a known issue? Iphone SE (2022). Battery health is 93%. iOS 17.0.3."

Yes. This is a well-known issue.
Troubleshooting Battery Draining iPhone After iOS17 Update:
Is iOS17 Installed?...
A. Downgrading the iOS:
Unfortunately, the iOS cannot be downgraded to a lower version. So, you only option, when it comes to restoring from an iPhone backup, is to restore from on that is of the same iOS version.
B. Report this to Apple...
Overeating iPhone and draining iPhone batteries are a well-known issues. Power is a big concern for iPhone series compatible with iOS 17. Question is: "Just how many people have actually reported this to Apple?"
So, do your Part: Provide Apple with feedback on this, letting them know about this issue. Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come. Apple will know nothing of this, if you don't report it to them.
