A 20% smaller notch, two and a half hours more battery, sensor-shift stabilization, Cinematic mode, and 128 GB as the base storage.

The 13 is a 12 with a better battery and a smaller notch. That was enough. Apple shrank the TrueDepth housing by 20 percent and moved the earpiece to the top edge, which nobody had asked for and everybody noticed. Battery life went up two and a half hours over the 12, helped by the more efficient A15 Bionic and a physically larger cell squeezed into the same body. The cameras moved diagonally to make room for the larger sensor from the 12 Pro Max, which brought sensor-shift stabilization to the non-Pro line a year after it first appeared. Cinematic mode arrived. It recorded video with a shallow depth of field and racked focus between subjects on its own, it was 1080p only at launch, and it was rather obviously a first attempt. Base storage finally moved from 64GB to 128GB, which mattered more day to day than anything else on this list.
The 13 was read as a refinement of the 12, with the Pro Max camera hardware moving down the range.
While this year's iPhones aren't major improvements over their predecessors, they offer just enough changes that might tempt you to upgrade, particularly if you're still on an iPhone 11 or older.
But, as expected, they're excellent phones with little to complain about.
