I have had the same experience. I use an iPhone 11 with the latest iOS version and record to the internal memory.
I have noticed that in my case it happens when:
a) Stabilisation is activated. If I turn it off completely, no frames are dropped.
b) When I record at higher frame rates. If I record at 30 fps, no frames are dropped.
With version 1.0 of the camera app, it was possible to switch off the HDMI feed. When I did this, I also had no dropped frames.
