System Data and “Other” Storage
Updated: April 8, 2026
iOS buckets caches, indexes, logs, and temporary files under System Data. It can grow after updates or indexing and sometimes shrink after a restart or time.
Safe steps
- Restart; wait 48 hours after major iOS updates.
- Clear Safari cache; offload large apps.
- Delete old Messages attachments.
- Back up then restore is the heavy hammer—see free up storage.
