Symptoms
- Storage settings show a large 'Other' or 'System Data' category
- Can't tell which app is responsible
- Storage stays full even after deleting some apps
Likely causes
- CommonApp caches and temporary files accumulatingMany apps, especially browsers, streaming, and messaging apps, build up cache over time that falls into this general category.
- CommonDownloaded offline content (podcasts, music, videos, messages with attachments)Media saved for offline use is often counted separately from the app itself.
- PossibleCorrupted or orphaned temporary filesInterrupted downloads or updates can leave stray files behind.
What to do
- Offload unused apps in settings (this removes the app but keeps its data, freeing significant space while letting you reinstall it later).
- Clear the browser's cache and history if you use Safari or Chrome heavily.
- Delete old text message threads with large photo/video attachments, since messages count toward this category.
- Restart the iPad after cleanup, since some freed space registers only after a restart.
- As a last resort for a stubbornly large 'Other' category, back up your data and perform a full erase and restore from backup, which clears accumulated system clutter.
