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.

Solution 2 – Check the Lightning cable and the port

Usually, these errors occur on any system while you are trying to connect your iPhone to a PC/Mac because of lightning cable or port issues.

Firstly, we suggest you check the lightning cable you are using to connect for any damage or whether it is broken. If yes, try replacing it with a new lightning cable. Make sure you get it from the Apple authorized store to avoid getting third-party duplicate ones. Also, ensure the port of your computer where you plug the lightning cable is in working order.
