I have not used a screen protector for maybe 5-6 years now. I recently upgraded to an iphone 13 from the 7 because it finally died on me. What I've found protected my phone from drops is the use of a good case. I've been using the official leather cases for both phones.

Because the screen is recessed into the case, when dropping on a flat surface, the screen will never come into contact with the surface its dropped on. It also protects against corner impacts which no screen protector will help against.
