2. Deleting junk files and application remnants

Even after deleting apps, their “tails” remain on the phone: configuration files, log files, temporary data. For example, after uninstallation Facebook there may be up to 200 MB unnecessary files. The system also creates error dumps (.dmp), which take up hundreds. megabyte.

How to find and remove junk:

• 🧹 Use the built-in tools:
  • On Samsung: Settings → Device care → Memory → Garbage.
  • On Xiaomi: Security → Cleaning → Garbage.
  • On "clean" Android: Settings → Storage → Free up space → Files for removal.
• 🔍 For deep cleaning, install Files by Google (official application from Google). It finds:
  • Duplicate files;
  • Old screenshots;
  • Unused APK files;
  • Remains of deleted applications.

Pay special attention to the folder Download —unnecessary APK files (application installation packages) often accumulate here and take up space. 50-100 MB each. You can safely delete them if you do not plan to reinstall apps manually.

Type of junk files	Where to look	How much space occupies
Remains of deleted applications	/storage/emulated/0/Android/obb/ /data/data/ (root access required)	From 100 MB to 2 GB
Error dumps (.dmp)	/data/tombstones/ (required root access)	From 50 MB to 1 GB
Temporary download files	/storage/emulated/0/Download/	From 200 MB to 5 GB
Application log files	/storage/emulated/0/Android/data/[package_name]/files/logs/	From 10 MB up to 500 MB

⚠️ Attention: Deleting files from folders /data/ or /system/ without root access may cause the system to crash. Use only official tools or proven file managers (for example, Solid Explorer).

3. Optimization. messenger storage: up to 5 GB of free space

Messengers are the main memory hogs. For example, Telegram caches all media files by default, and WhatsApp automatically saves photos and videos to the gallery. Over a year of use, one chat can take up to 3-4 GB.

6. Hidden Android functions for clearing memory

B Android There are little-known tools that help free up space without deleting apps. They are not advertised, but they work on most devices.

Ways you might not know about:

• 🗑️ Cleaning downloads:
  • Go to Files by Google → Categories → Downloads.
  • Click Select all → Delete (will delete all files older than 30 days).
• 🔄 Reset system cache:
  • Go to Settings → Storage → Free up space → Advanced → Clear system cache.
  • This option deletes temporary files of updates and system processes (can free up to 1 GB).
• 📂 File compression:
  • Use the application ZArchiver or RAR to archive old photos and documents.
  • Compress to format .zip or .7z can reduce the size of files by 30-70%.
• 🔍 Search for large files:

  adb shell find /storage/emulated/0/ -type f -size +100M -exec ls -lh {} \;

  This command (executed via ADB) will show all files larger than 100 MB. To use it, you need developer rights.

Another secret method is cleaning application data Google Play Services. This service is responsible for updates and can accumulate up to 500 MB of unnecessary files. data-i="259">Go to

  • FFmpeg (for advanced users): command for compression without loss of quality:

    ffmpeg -i input.mp4 -vcodec libx265 -crf 28 output.mp4

Example: 1 minute video in Full HD (1080p):

• Original size: 120 MB;
• After compression to Video Compress: 30-40 MB (quality loss is minimal).

⚠️ Attention: Compressing videos with high bitrates (for example, recorded on GoPro or DJI Osmo) may take a long time. Use a charger to avoid draining the battery.

8. Setting up automatic memory cleaning

1. 90%+).

2. Are notifications enabled for the application? the problem remains, try reinstalling the cleaning application. Files by Google or Smart Manager (on Samsung).

3. Are there any restrictions for background activity in the battery settings (on Xiaomi and other Chinese brands).

If the problem persists, try reinstalling the cleaning app.

FAQ: Frequently asked questions about clearing Android memory

Is it possible to clear memory without root access?

Yes, all methods in this article work without root access. The only exceptions are deep cleaning of system folders (for example, /data/tombstones/and removal of pre-installed applications (bloater).

For most users, root is not needed - standard tools Android and applications like Files by Google enough to free up 3-10 GB memory.

Why is space not freed up after clearing the cache?

This happens for two reasons:

1. The system cache is not updated: After cleaning, restart the phone - only then the system will recalculate the free space.
2. Files are occupied by processes: Some applications (for example Google Chrome) immediately restore the cache. Close all apps before cleaning.

Also check if the option Adaptive battery (on Android 9+) is enabled - it can limit the background activity of cleaning utilities.

How to clear memory on a phone with Android Go?

Android Go (simplified version for weak smartphones) has limited cleaning tools. Use:

• Built-in utility: Settings → Storage → Free up space.
• Lite applications: Google Go, Gallery Go, Files Go (optimized to save memory).
• Manual cleaning:
  • Delete the cache via Settings → Applications.
  • Transfer photos to a memory card (if supported).
  • Disable auto-update of applications in Google Play.

On Android Go it is not recommended to install heavy cleaning utilities (for example, CCleaner) - they can slow down the system.

What are “other files” in the Android storage and how to delete them?

Category Other files in Settings → Storage includes:

• System log files (.log, .dmp);
• Application configuration files (.xml, .db);
• Temporary update files;
• Remains of deleted apps.

To delete them:

1. Use Files by Google (section Cleanup → Other files).
