Haptic feedback, slight random bumps occur throughout the phone usage day

My iPhone’s haptic feature seems to be triggered randomly throughout the day. It is a very small pulse, maybe 1/60 th of a second, and it will happen multiple times, usually approximately 10 seconds to a minute or so apart. It can happen while watching YouTube videos or at other random times throughout a normal day’s of use. I really don’t want to turn off haptics, but whatever is happening, is there a way to troubleshoot this issue to find out what exactly is going on? It is an iPhone 13 Pro Max.
