I tried taking some late evening shots hand held with the iPhone 11 pro. It was just a notch less than pitch black outside, and the phone picked a 10 second exposure for night mode.
This is handheld, no tripod, no leaning on a rock or anything like that. It seems back focused, but overall I'm very impressed. No way would I have had a shot this steady looking out of a DSLR or a FF mirrorless after 10 seconds. And the colors actually turned out very close to true.
Also attached is a shot of the same scene taken with a short exposure - 1/4 seconds, according to EXIF.
