The best distance to shoot a portrait with a mobile phone;

Take pictures with your mobile phone. From the cognitive point of view, the focal length of most smart phones is between 24 and 24-35mm, which is a little larger than our eyes that see the world everyday.

Based on this, the perspective of mobile phone portrait shooting is mostly plain and relaxed, which will be slightly wider than our naked eye view of the world, neither too wide nor too narrow.

Therefore, it is a good choice to take portraits with mobile phones, close-ups within 1m from people, half-length photos within 3m from people, full-length photos within 5m from people, and photos of environmental people.
