Step by step

1. 

   Open Storage

   Go to Settings, About phone, and tap Storage. Ours read 38.7GB/256GB.

   Done

2. 

   See what uses the space

   The page lists Apps and data, Images, Audio, Video, APKs, Documents, Archives, System files and System. On ours, Apps and data was 9.24 GB and System files 18.42 GB.

   Done

3. 

   Open Deep clean

   Open the Security app. Deep clean is one of the tiles under the big score; ours read 38.7 GB/256 GB occupied. Tap it.

   Done

4. 

   See what can go

   Deep clean shows how full the phone is (15% on ours) and how much can be freed: Take 2 steps to free up 6.25GB. Uninstall apps and Clear app data are below.

   Done

5. 

   Uninstall apps you don't use

   Uninstall apps lists apps by size, marked Not recently used. Ours started with MONOPOLY GO (440MB), N26 (438MB) and Mech Arena (412MB). Tick the ones to remove and tap Uninstall. We ticked nothing.

   Done

If you do not see this option

• No Delete videos or Delete big files? Xiaomi lists Delete videos and Delete big files in Deep clean too. Ours showed only Uninstall apps and Clear app data. Our phone had no photos or videos. Source: Generic User Guide for HyperOS 3.0
• No Deep clean in Security? Xiaomi lists Deep clean as a Security app feature. Search Settings for Deep clean if you can't see the tile. Source: Generic User Guide for HyperOS 3.0

If this does not work

• System files take a lot? On ours, System files (18.42 GB) and System (11.03 GB) were the biggest parts. You can't delete those.
• Still full? Google suggests removing downloaded files and apps you don't use, and backing photos up before you delete them. Source: Free up space
