Step by step

1. 

   Open About device

   Open Settings; it is near the bottom.

   Done

2. 

   Tap Storage

   The card shows used and total space.

   Done

3. 

   See what uses the space, then tap Clean up

   Apps, Images, Videos, Audio, Documents, APKs, Archives and more, each with its size. Clean up is the button at the bottom.

   Done

4. 

   Read the Phone Manager notice

   The first time, Phone Manager shows a notice that links its user agreement and privacy terms, with Agree and continue or Disagree; the choice is yours.

   Done

5. 

   Tap Clean

   It shows the junk total at the top. View details lists what will go first.

   Done

6. 

   Check what was cleared

   Ours said 114 MB cleared, with Storage at 29,1 GB of 256 GB used.

   Done

If you do not see this option

• Older OPPO phone? OPPO gives Settings, Storage on ColorOS 11 and 12, and Settings, Additional Settings, Storage on ColorOS 3.0 to 7.2. On some phones the File Manager app also shows the space left. Source: How to Check OPPO Phone Storage
• No Clean up button? Open the Phone Manager app instead: OPPO gives Phone Manager, Clean Up Storage or Clean Up, then Clean, and says the button may read Clean, Clear All or Clean Up depending on the version. Source: How to Check OPPO Phone Storage
• Want more than junk? App cleanup and Lossless optimisation are further down the Cleanup page.

  

If this does not work

• Deleted something by mistake? Check Recently deleted in Storage; ours was 0 B.
• Space fills again? OPPO says Clean up removes temporary, cookie and cache files that are created each time you open or download something, so junk builds up again. Run it now and then, or clear one app's cache from the link below. Source: How to Check OPPO Phone Storage

About this guide

The screenshots are from our OPPO Reno13 5G, the European model CPH2689, with ColorOS 16.0.5 and Android 16 (build CPH2689_16.0.5.1001(EX01)), in Dark mode. The first time, Phone Manager showed a welcome screen with Agree and continue and Disagree. We tapped Clean once; it removed 114 MB of junk files.

Good to know
