Please describe what you mean by overheating? When an iPhone actually overheats, you will see a red thermometer on the screen with a notification the phone can't be used until it returns to a normal operating temperature. If you are not seeing the red thermometer, your phone isn't overheating. That doesn't mean it may be hot at times, depending on what you're doing on the phone. Streaming video/music, or heavy usage of social media apps, like FaceBook, Instagram, WhatsApp, etc., taking photos/videos, playing games, etc., will make the battery work harder. When the battery works harder, it generates heat naturally.

What is the Battery Health on your iPhone? Open Settings > Battery > Battery Health - if it is 80% or lower, the battery is failing and a battery replacement should be scheduled at your Apple Store Genius Bar at your earliest convenience --> Apple Service and Repair for iPhone Battery - Apple Support

Are you saying that the screen on your iPhone looks like this?

If not, your iPhone is not overheating.
