Open Settings > Storage > Cleanup (or Optimizer > Cleanup on some Magic OS builds) and tap Clean Up to remove cache and junk. To see what is really filling the phone, check the storage breakdown first, then handle large files and per-app caches yourself. Magic OS automates the routine cleanup; the heavy media files are still up to you.

TL;DR

  • Check the breakdown at Settings > Storage before deleting anything.
  • Run Optimizer > Cleanup > Clean Up for cache and junk files.
  • Clear one app's cache at Settings > Apps > Apps > [app] > Storage > Clear Cache.
  • Use the Cleanup view's category cards to find large videos and duplicates flagged by the system.
  • The optimizer clears junk; it does not compress or truly de-duplicate your media library.

What is taking up space on my HONOR?

Open Settings > Storage. Magic OS shows usage split across Apps, Images, Videos, Audio, and Other. On most full phones, video and cached app data lead, with photos smaller than expected. Read the breakdown before you start so you target the real space hogs. For the full Android playbook, see how to free up space on Android without a factory reset.

How do I run HONOR Cleanup?

Open the Optimizer app, tap Cleanup (or go straight to Settings > Storage > Cleanup). Magic OS scans and offers a one-tap clean for cache, ad junk, and residual files. Below that are category suggestions such as Photos, WhatsApp, Large files, and Duplicate photos. Open each suggestion to review the list before confirming. The system flags candidates conservatively, so nothing personal is removed without your tap.

How do I clear cache for one app?

Go to Settings > Apps > Apps, pick the app, then Storage > Clear Cache. This safely removes temporary files only. Avoid Clear Data, which wipes the app to a fresh state and logs you out. Focus on your few largest apps instead of clearing everything, because most caches are small and refill quickly. Browsers are frequent space hogs, so if Chrome is bloated, read why Chrome takes up so much space on Android.

How do I deal with large media?

Magic OS Cleanup lists Large files sorted by size; open it to spot oversized videos, downloads, and documents. For long-term breathing room, back up big videos to the cloud through the Gallery or Files app, then delete the local copies. If your HONOR model has a microSD slot, you can move photos and downloads to the card from the Files app. Installed apps stay on internal storage regardless.

What Magic OS does natively, and where it stops

The HONOR optimizer reliably clears cache, residual files, and obvious junk, and it will even suggest some duplicate photos. Where it stops is real media work: it does not compress your 4K clips, catch every near-duplicate burst, or give you a single ranked list of the biggest files across all folders. That deeper cleanup is where the real gigabytes are, and it is left to you. The Cleanor app is built for that step, surfacing your largest files and duplicates so the choice is fast.

A note on recoverability

Clearing cache is effectively reversible, because apps rebuild it on next use. Deleting media is not automatically reversible. Photos and videos usually sit in the Gallery Recently deleted album or Google Photos Bin for about 30 days, but files deleted from the downloads folder go immediately. Back up anything important before a large clean.

FAQ

Does HONOR Cleanup delete personal files?

Not on its own. The one-tap clean removes only cache and junk. Personal items like photos, large files, and duplicates are shown in lists you must review and confirm before anything is deleted.

Why is my HONOR storage full so fast?

Video and messaging media fill storage quickest. High-resolution clips are large, and chat apps store every photo and video you receive. Open Settings > Storage to see the actual breakdown before deleting.

Is it safe to clear cache on a HONOR phone?

Yes. Cache is disposable temporary data. Clearing it frees space right away and is completely safe; apps simply rebuild what they need the next time you open them.

After Magic OS has cleared the junk, the Cleanor app handles the large files and duplicates left behind. It is the simplest way to clean up phone storage without guesswork.
