Same. Mobile phones have excellent image processing, displays, and interfaces, but small optics and sensors. Dedicated cameras have big optics and sensors, but bad/limited image processing, displays, and interfaces.
Whatever denoising algorithm they put on the camera, your laptop will do it better. Stripping back the processing means you can take photos at 60fps with minimal battery drain.
But a very small sensor paired with a good telephoto lens is an interesting option. You can get away with much less glass for the same zoom but the downsides of a small sensor. So you get something like the Nikon Coolpix P1100 which has 2000mm full-frame equivalent magnification, but only 16MP and terrible low light performance.
