Not sure if this is true for macro. For a given angle of view, the amount of light collected is determined by the absolute diameter of the aperture (as opposed to the f number). It’s rarely practical to use a very wide aperture for macro photography on a DSLR for depth of field reasons. People do all sorts of unnecessarily complex calculations with crop factors, but in this scenario all you have to think about is the diameter of the aperture in mm. The phone has an aperture of perhaps around 3-4mm. You’re unlikely to use a wider aperture than that shooting macro on APS-C or full frame.
