Storage

Hello! I completely cleaned my iPhone, through the settings I deleted all the information. And when I went into a practically empty phone in memory, I saw that 10 GB was already occupied there, only 6 remained. And the bulk of this is the "system" and the "other". I updated the system, and did not even install anything other than basic applications. Tell me what it is and how to fix it, because it turns out that I have a phone with 6 GB of memory
