They really don't. I regularly take photos outside, at night, in ambient light with my Fujifilm X-Pro3 and 56mm f/1.2. I'm stretching the limits of it a bit, using high ISO and as low a shutter speed as I can get away with. In the same lighting conditions, an iPhone will basically take 3-5 shots and composite them together in software. The result, predictably, is unusable for most moving subjects.
