Why so? Has something occurred in iOS16 that you do not favor?

Provide Apple Feedback:

Do your part: Let Apple know what is going on here. Provide them with feedback on this. They may not get back to you directly, but the more feedback they received on this, the more they will know what their pursuers prefer, and features to include in iOS versions to come.

1. Go Here: Feedback - iPhone - Apple
2. Comment: on why you do not prefer iOS16.
3. Select: "Performance" for the "Feedback Type"
4. Proceed from there aw necessary

Downgrading the operating system is not supported by Apple.
