If you’ve just enabled Apple Intelligence, it’ll also go through all your Photos and detect objects, faces, pets, POIs, settings, etc… Depending on the amount of photos, this can take a few days to complete. (Should only happen while the phone is connected to a charger, though.) During that time, some sluggishness is to be expected. However, after a few days, the phone should be snappy again.

At least I can’t notice any such issues on my 16 Pro. And I’m using AI since it became available in the Betas here in the UK.

But technology and production methods got way cheaper in the past few years…
