Scans device storage for junk, identifies large files by size and previews photo compression savings before you commit. Made by QI QI MI, the Android utility bundles storage overview, junk cleanup, photo compression, battery diagnostics, RAM monitoring, a notification organizer, and a speaker maintenance tool. The app targets Android users who need straightforward space recovery and basic device health metrics within a single interface.

What does Storage Cleaner actually do?

Storage Cleaner scans internal storage and presents a visual storage overview, then flags temporary logs, obsolete APKs, and large media for review. The app offers a photo compression mode that shows an estimated output size before compression, and a large-file browser that sorts items by size and type so you can delete selectively. Those mechanics keep decision steps visible: scan, review, preview, then apply.

Does it affect system resources while running scans?

The app reports RAM usage and exposes running-app information, and it uses device permissions to inspect files, which means scans operate within the device's normal permission model. Feature availability and behaviour depend on the device model and granted permissions, so the scope of a scan can change by handset. The app also supplies a shortcut to the system uninstall flow for removing apps rather than force-writing deletions itself.

Is it safe to use on a daily device?

Storage Cleaner requests permissions to access storage and system details, and it displays battery metrics such as temperature and voltage from the device sensors. Photo compression provides a preview before changes, which reduces accidental quality loss. Because the tool channels uninstalls through the system flow and previews compression output, it stays within standard Android controls rather than silently overwriting user files.

Do you need technical knowledge to operate it correctly?

The app groups functions into an accessible dashboard and labels tools like "Junk Cleanup," "Large File Management," and "Notification Organizer," which lowers the learning curve for casual users. Advanced users who need deeper forensic recovery or enterprise-grade diagnostics may find the tool less specialised, since it combines several maintenance tasks into one interface rather than offering granular developer-level controls.

Practical pick for casual users who want combined storage and health tools

The app suits Android users who prefer a single utility that shows storage status, trims obvious junk, previews image compression, and reports battery and RAM data. It trades specialist depth for multi-tool convenience, so use its preview features and the system uninstall shortcut before making irreversible changes. Recommended.
