What is meant by others in iphone storage? System sata,photos, app all inderstood. How we can remove it?

Hello diljo240,

The "Other" storage category contains the following:

Other: Non-removable mobile assets, like Siri voices, fonts, dictionaries, non-removable logs and caches, Spotlight index, and system data, such as Keychain and CloudKit Database. Cached files can't be deleted by the system.

How to check the storage on your iPhone and iPad

To help troubleshoot System and Other taking up larger than expected storage, ensure iOS is updated. Updating iOS can help clear up unexpected software issues: Update your iPhone or iPad - Apple Support

"Update your iPhone or iPad wirelessly

1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install."

If the issue continues, reach out to Apple Support directly to help investigate the behavior. You can use the following link to reach out: Contact - Official Apple Support
