Part 1. What Causes iPhone Says Not Enough Storage But There Is?

When your iPhone displays the Not Enough Storage message despite having plenty of space, it is indicative of underlying issues within the device's storage management system. These issues can range from accumulated cache files to mismanagement of iCloud storage. If your iPhone says not enough storage but there is, it can arise from the following causes.

Cause 1. Full iCloud Storage

One of the main culprits behind the problem is full iCloud storage. Even if your iPhone has enough physical storage for data and files, iCloud backups might be consuming the available space.

Cause 2. Accumulated Cache Files

Over time, various apps accumulate cache files that take up significant space on your device. These accumulated cache files are not always necessary but are constantly stored on the device.

Cause 3. System Junk Files

System junk files, including temporary files and logs, can also contribute to the storage discrepancy issue. These files often go unnoticed but can collectively occupy a substantial amount of space.
