All digital sensors are light hungry. The more light they have to work with, right up to the limits of what the sensor can handle, the happier they are, and the better the results. It is not a matter simply of ISO…adjusting the sensitivity of the sensor to accommodate lower light levels will adversely effect image quality…but even at the base ISO there is simple more detail and more subtle color tones in an image taken in good light. And phone cameras, because of their truly tiny sensors, are particularly responsive to changes in light level.
