How to completely clear the clipboard on Xiaomi Redmi 6: all working methods

The clipboard on Xiaomi Redmi 6 is a temporary storage for copied texts, links and images that many users forget to clean. Over time, dozens or even hundreds of items accumulate here, from randomly copied passwords to private messages. This not only takes up precious RAM (especially for the budget Redmi 6 with 2-3 GB of RAM), but also creates risks of leakage of confidential data.

Unlike modern flagships, where the clipboard is controlled automatically, on Redmi 6 running MIUI 9-12 (depending on the firmware version), this process requires manual control. Moreover, standard cleaning methods often work incorrectly: for example, the “Clear All” button in the buffer menu may not remove elements completely, leaving them in the cache of system applications. In this article, we will analyze 5 proven methods – from basic to advanced, including hidden MIUI settings and third-party utilities.

Why it’s important to clean up the clipboard on Redmi 6 regularly

On Xiaomi Redmi 6, the clipboard is implemented through the com.miui.clipboard system app, which defaults to save up to 50 last items (including text, images and links).

• 📱 RAM overload: Each buffer element takes between 10KB and 2MB (for images) on a device with 2GB of memory, this can lead to slowdowns when multitasking.
• 🔒 Security risks: Passwords, card numbers, or personal correspondence remain available for any application with buffer read permissions (such as keyboards or file managers).
• 🤖 Conflicts with MIUI: A filled buffer may cause malfunctions in the standard Mi Keyboard keyboard or the Notes app».
• 📊 Incorrect cache operation: after updating to MIUI 11+ Some users are faced with duplication of buffer elements.

It is especially critical to clear the buffer before selling or transferring the phone. Even after resetting to factory settings, individual items can be saved in Mi Cloud backups if not removed in advance.

Method 1: Standard cleaning through the clipboard menu

The simplest method that works on all versions of MIUI for Redmi 6, however, has a limitation: it only removes visible elements, but does not affect the cache of system applications.

1. Open any field to enter text (for example, in “Messages” or “Notes”).
2. Hold the blank field with your finger until the menu appears. Select the clipboard (or clip icon).
3. In the upper right corner, press three dots. ⋮ and select the Exchange Buffer Management.
4. Click Clean All (or highlight individual items and remove them one by one).

⚠️ Attention: MIUI 10 and below, this may not work because of a permission bug. If the "clean up all" button is inactive, move on to the next method.

Close all applications in multitasking

Disable sync with Mi Cloud (Settings → Xiaomi Account)

Check the space in memory (should be ≥ 500 MB)

Reboot the phone (optional)

Method 2: Cleaning through application settings

This method removes the cache of the clipboard system application, which helps get rid of “invisible” items that do not appear in the standard menu.

1. Go to Settings → Applications → Application Management.
2. In the search bar, type a buffer or clipboard. Select the clipboard app (or com.miui.clipboard).
3. Click Warehouse → Clear the cache and Clear the data.
4. Confirm the action. The phone might hang for a while -- that's okay.

After this procedure, all buffer elements will be removed without recovery, including the history of the past 30 days.

Method 3: Using a file manager (for power users)

If standard methods do not work, you can manually delete clipboard files through a root or ADB file manager. This method is suitable for users who previously received root access or installed custom firmware.

1. Install a file manager with root support (such as Root Explorer or FX File Explorer).
2. Go to: /data/data/com.miui.clipboard/databases/ /data/data/com.miui.clipboard/cache/
3. Delete all files with the.db and.journal extensions (such as clipboard.db).
4. Reboot the phone.

⚠️ Attention: Wrong actions in the folder /data/data/ If you have no experience with root, use the method 4 s ADB.

Method 4: Third-party applications for buffer management

If the system methods don't work, you can use third-party utilities, which offer advanced features: automatic cleaning, data encryption and synchronization between devices.

• 📋 Clipboard Manager – saves history, but allows you to selectively remove items and configure autocleaning.
• 🔒 Clip Stack – encrypts the data you copy and clears the buffer on a schedule.
• 🧹 Clean Master – has a built-in module for cleaning buffer and cache (but requires caution with permissions).

When installing third-party applications:

1. Open the clipboard settings (Settings → Additional → Clipboard).
2. Turn off the system buffer (Disable the MIUI clipboard).
3. Set up the new application as the main one for copying.

💡

Before installing third-party utilities, check their Google Play rankings and reviews. Some buffer management apps (like Clipboard Actions) request redundant permissions, which can be a security risk.

Method 5: Reset to factory settings (last resort)

If the clipboard is full of critical data (like before selling your phone) and other methods don’t work, it’s a complete reset, which will remove all data from the device, including apps, photos, and settings.

1. Back up important data via Mi Cloud or on PC.
2. Go to Settings → Additional → Recovery and Reset.
3. Select Resetting → Delete all data.
4. Enter the password (if installed) and confirm the action.

Once reset, the phone will reboot to its original state, and the clipboard will be empty, but it will be impossible to restore the elements that were previously deleted.

💡

Factory reset is the only way to guarantee that you will remove all traces of the clipboard, including hidden system files, and only use it in extreme cases, as the process is irreversible.

Frequent Mistakes and How to Avoid Them

When cleaning the clipboard on Redmi 6, users often face typical problems:

• ❌ The "Clear Everything" button is inactive → Solution: Update MIUI before the latest version or use it ADB (see method 3).
• ❌ After cleaning, the elements are returned. → Reason: sync with Mi Cloud. Turn it off in Settings → Xiaomi account → Synchronization.
• ❌ Image history not deleted → Images are stored in the gallery cache. Clean it through Settings. → Warehouse → Clear the cache.

Another common mistake is using Google Play's "memory optimizers," many of which are (e.g., "memory optimizers, DU Speed Booster) promise to clear the buffer, but in fact only remove the browser cache without affecting the system clipboard.
