Open Settings > Storage to see exactly what is using your space, then run the built-in cleaner at Phone Manager > Storage Cleaner. That clears system junk and cache in one tap. To go deeper, you delete cached app data, old downloads, and large media yourself.

TL;DR

  • Check usage first at Settings > Storage so you target the biggest categories.
  • Run Phone Manager > Storage Cleaner for cache and temporary files.
  • Clear individual app caches at Settings > Apps > App Management > [app] > Storage Usage.
  • Move photos, videos, and downloads to an SD card if your model has a slot.
  • The native cleaner handles junk; it does not compress or de-duplicate your media.

What is actually using my storage?

Go to Settings > Storage. Realme UI breaks usage into Apps, Photos, Videos, Audio, and Other. On most full phones the top two are video and app data, not photos. Knowing the split stops you from deleting the wrong things. If you want the bigger picture beyond one device, our guide on how to free up space on Android without a factory reset covers the safe order of operations.

How do I run the Realme cleaner?

Open Phone Manager > Storage Cleaner (some builds label it Cleaner). Tap Clean Up to remove cache files, ad junk, and leftover installer files. Below that you will see categories like Photos, WhatsApp, Downloads, and Apps not used recently. Review each list before confirming. The Realme cleaner is conservative by design, so it rarely touches anything you need, but it also leaves the largest files for you to handle.

How do I clear cache for one app?

Go to Settings > Apps > App Management, tap the app, then Storage Usage > Clear Cache. This is the safe button. Avoid Clear Data unless you are willing to sign in again and lose in-app settings, because that wipes the app back to a fresh install. Chrome and other browsers are common offenders here; see why Chrome takes up so much space on Android if your browser has ballooned.

How do I use an SD card?

If your Realme model has a microSD slot, insert a card and open Settings > Storage to confirm it is mounted. You can then move photos and downloads through the Files app: select items, tap Move, and choose the SD card. The camera can also save new shots to the card in Camera > Settings > Storage location. Note that apps themselves mostly stay on internal storage, so an SD card helps media, not app bloat.

What Realme UI does natively, and where it stops

The native cleaner is good at the unglamorous work: cache, residual files, and temp data. What it does not do is compress your 4K videos, find near-duplicate burst photos, or tell you which single files are the biggest. That last mile, the part that actually frees gigabytes on a media-heavy phone, is left to you. That is the gap the Cleanor app is built to close: it surfaces your largest files and duplicates so you can decide what stays.

A note on recoverability

Clearing cache is always safe and reversible in effect, because apps simply rebuild it. Deleting media is not. Photos and videos removed through the Files app usually pass through the Recently Deleted album in Google Photos or the Gallery trash for around 30 days, but downloads deleted directly are gone immediately. Back up anything you are unsure about before a big clean.

FAQ

Does clearing cache on Realme delete my photos?

No. Clearing cache only removes temporary files apps generate to load faster. Your photos, videos, messages, and account logins are untouched. The cache rebuilds on its own as you use the app again.

Why is my Realme storage full when I have few apps?

Usually video and app data are the culprits, not the apps themselves. Messaging apps store every received photo and clip, and 4K video grows fast. Check Settings > Storage to see the real breakdown before deleting anything.

Is it safe to use the Realme Storage Cleaner regularly?

Yes. The Storage Cleaner targets cache and junk, which are safe to remove anytime. It will not delete personal files without showing you the list first and asking you to confirm.

When the native tools have done their part and you still need room, the Cleanor app finds the large files and duplicates that the cleaner leaves behind. It is the simplest way to clean up phone storage without guessing.
