Tecno and Infinix phones run HiOS and XOS, which ship with a built-in cleaner called Phone Master (sometimes labeled "Cleaner"). The fastest fix is open Phone Master > Clean / Storage Cleaner > Scan > Clean, which clears junk and cached files in one pass. For stubborn space, clear individual app caches at Settings > Apps & notifications > [app] > Storage > Clear cache, and move photos and downloads to an SD card if your model has a slot.

TL;DR

  • Open the preinstalled Phone Master app, run Clean / Storage Cleaner, and tap Clean for a quick win.
  • Clear a single app's cache at Settings > Apps > [app] > Storage > Clear cache without losing its login.
  • Move photos, videos, and downloads to an SD card to free internal storage on models with a slot.
  • Avoid "Clear data" and aggressive "deep clean" options that delete app settings or files you still need.
  • A factory reset is a last resort, not a cleanup step; there are safer ways first.

How do I use Phone Master to free up space?

Open Phone Master (search your app drawer if it is not on the home screen), tap Clean or Storage Cleaner, let it scan, review what it found, and tap Clean. It targets cache files, temporary files, and obvious junk by default, which is safe. Be careful with the Deep Clean or App Manager sections, which can suggest deleting downloads, large videos, or app data you may want to keep; uncheck anything you are unsure about before confirming.

How do I clear a single app's cache on HiOS or XOS?

Go to Settings > Apps & notifications > App management (wording varies by version), tap the app, then Storage > Clear cache. This removes temporary files while keeping your login and in-app data. Use this for chat and social apps that grow large. Do not tap Clear data unless you are willing to sign in again and reset that app's preferences.

Should I move files to an SD card?

If your Tecno or Infinix has a microSD slot, this is one of the biggest wins. Open Files or File Manager, select photos, videos, and downloads, and move them to the SD card. You can also set the camera to save new photos to the card in the Camera settings. Note that some apps cannot run from an SD card, so move media, not apps, for reliability.

What the OS does natively, and where it stops

HiOS and XOS auto-clear some temporary files and warn you when storage runs low, and Phone Master automates a basic cleanup. Where it stops: the built-in cleaner focuses on obvious junk and can be overzealous in its deep-clean prompts, and it will not reliably catch duplicate photos, large forgotten videos, or per-app bloat across every app. Those still need a manual look.

What this cannot do (and a safety note)

Cleaning cache and moving media frees real space, but it will not turn a 32 GB phone into a 128 GB one, and no cleaner can safely delete system files to gain storage. Treat "boost" and "deep clean" buttons with skepticism: clearing cache is safe, but deleting app data, system files, or unread downloads is not reversible. If a cleaner offers to remove something you do not recognize, skip it. Keep a factory reset as a true last resort, and back up first.

FAQ

Is Phone Master safe to use on a Tecno or Infinix phone?

Yes, for its standard cache and junk cleaning. The risk is in the deep-clean and app-manager prompts, which can suggest deleting files you want to keep. Stick to the basic clean, review the list, and uncheck anything unfamiliar before confirming.

Will clearing cache delete my photos or chats?

No. Clearing cache only removes temporary files. Photos stay in your gallery and chats stay in their apps. You only risk data loss if you choose Clear data for an app or manually delete media from File Manager.

Why is my storage still full after cleaning?

The usual culprits are photos and videos, large app data (messaging apps especially), and offline downloads, none of which a cache clean removes. Check Settings > Storage to see the breakdown, then move media to an SD card or delete what you no longer need.

For a clearer picture of what is filling your phone, the Cleanor app scans your storage and helps you spot large files and duplicates so you can clean up phone storage without risky guesswork.
