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.
