Solution 1 – Clear up space on your iPhone
When you try to connect your iPhone to a computer and open iTunes, it first checks for any updates and immediately throws an error if there is no space left to update your iPhone with the latest update.
Therefore, we recommend our users try to delete any of the unwanted files which are occupying the space. If not possible, transfer those files to another device or back them up via iCloud. Upgrade your iCloud account capacity to back up more files.
When you have enough space on your iPhone, try it again to connect to a PC/Mac via iTunes without any error.
