Are you tired of your Android phone’s sluggish performance? One common culprit for this issue is a cluttered internal memory.

Over time, your Android device accumulates unnecessary files and data that can slow it down. In this tutorial, we will guide you through the process of cleaning your Android phone’s internal memory.

Gather the necessary tools

Before we begin, let’s gather the tools we need:

  • A computer with a USB cable
  • Your Android phone
  • A reliable file manager app (e.g., ES File Explorer)

Step 1: Backup your data

It is crucial to back up your data before cleaning the internal memory. Connect your Android phone to your computer using a USB cable. Copy important files such as photos, videos, and documents to a designated folder on your computer. This step ensures that you won’t lose any valuable information during the cleaning process.

Step 2: Identify and delete unnecessary files

To free up space on your Android phone’s internal memory, you need to identify and delete unnecessary files. Open the file manager app on your phone and navigate to the Internal Storage or SD Card folder. Look for folders such as Downloads, Cache, or Temp, which often contain temporary files or leftover downloads.

You can also check other folders like WhatsApp or social media apps for media files that you no longer need. Select these files one by one or use the multi-select option to mark multiple items simultaneously. After selecting the files, tap the delete button to remove them from your device.


  • Be cautious when deleting files: Double-check the files you are deleting to avoid accidentally removing important documents or personal data.
  • Clear app caches: Some apps store temporary data in their cache folders. You can clear these caches through the Settings of each app or by using the “Clear cache” option in your phone’s storage settings.

Step 3: Uninstall unnecessary apps

Unused apps take up valuable space on your Android phone’s internal memory. Identify and uninstall apps that you no longer use or need. To do this, go to Settings > Apps or Application Manager, and select the unwanted apps one by one. Tap the “Uninstall” button to remove them from your device.

Step 4: Move files to external storage

If your Android phone supports external storage (SD card), consider moving large files such as videos, music, or documents to free up space on the internal memory. Connect your phone to the computer using a USB cable and transfer these files to the SD card. Alternatively, you can use a file manager app to move files directly from internal storage to the SD card.

Step 5: Reboot your device

To finalize the cleaning process and optimize your Android phone’s performance, restart it after completing all the previous steps. This action refreshes system processes and clears temporary data that might still be lingering in the memory.

Congratulations! You have successfully cleaned your Android phone’s internal memory. By regularly performing these steps, you can maintain a clutter-free device with improved performance.


This tutorial provides general guidance for cleaning Android phone internal memory. The exact steps may vary depending on your device model and Android version. Always exercise caution when deleting files or uninstalling apps to avoid accidental data loss.
