Modern smartphones are becoming a digital archive of our lives, and over time, the storage Xiaomi Redmi can become overfilled with unnecessary data. One of the common problems is the accumulation of thousands SMS messagess, which take up space and slow down the messenger. Users are often looking for a way to quickly clear their chat history, but the standard interface doesn't always offer an obvious "Delete All" button. In this article, we will look at detailed methods that will help you completely clear the message database on your device.

Deleting messages may be required not only to free up memory, but also before selling the gadget or for purposes privacy. It is important to understand that the removal procedure on different firmware versions MIUI or HyperOS may differ slightly visually, but the logic of the actions remains the same. We offer several options: from manual cleaning through the menu to using third-party software and engineering teams.

Before taking drastic measures, make sure that you do not have important verification codes or memorable SMS. The deletion process is irreversible unless you have cloud backup configured. Let's look at what tools are available to owners Redmi to manage incoming correspondence.

Standard cleaning through the Messages application

The most obvious and safest method is to use the built-in functionality of the application Messages. However, unlike some other shells, there is no single button to delete the entire database at once. You will have to use the multiple selection mode. Open the application and tap the menu icon or hold your finger on one of the conversations to activate the selection mode.

After activating the editing mode, a counter of selected items will appear at the top of the screen. Here you can tick all the dialogs that you want to destroy. Please note that selecting thousands of messages may take some time and require scrolling through the list. To speed up the process, some versions MIUI allow you to select a group of messages for a certain period.

⚠️ Attention: Deleting correspondence through the standard menu does not always clear the database cache instantly. If the space is not freed up right away, try restarting the device.

After all the necessary dialogs are selected, click on the trash can icon in the lower or upper corner of the screen. The system will ask for confirmation of the action, since recovering deleted SMS it is impossible without a backup. Confirm the operation, and the selected chains will be moved to the trash can or permanently deleted, depending on the settings of your firmware version.

💡

If you have activated the “Trash” function in the message settings, do not forget to clear it too, otherwise the memory will not be completely freed. Go to the application settings and find the “Trash” item for final deletion.

Using the “Cleanup” function in the Security application

The company Xiaomi has integrated a powerful optimization tool directly into the system. The Security (Security) application has a built-in Cleaning module that scans the device for junk files, including old messages. This is one of the most effective ways to mass delete data without manually selecting each dialog.

Launch the application Security and select Cleaning. The system will analyze and offer to delete temporary files, cache and, importantly, “old messages”. The algorithm typically identifies messages older than 30 days or those containing attachments as candidates for deletion. You can select a category of messages and click the clear button.

  • 📱 Launch the Security application from the main screen.
  • 🧹 Click on the big green "Cleaning" button or the broom icon.
  • 📄 Find the “Messages” or “SMS” section in the list of junk found.
  • ✅ Click “Clear selected” to confirm deletion.

This method is convenient because it works at the system level and often ignores the limitations of the messenger interface. However, you should be careful: the algorithm may mark important notifications from banks as garbage if they arrived a long time ago. Always check the preview of the deleted data before the final click of the button.

Using third-party applications for batch deletion

If standard methods seem too slow or inconvenient to you, the store Google Play offers many utilities for managing SMS. Applications like SMS Backup & Restore or specialized “Cleaner” utilities allow you to select messages using checkboxes with the “Select All” function. This significantly speeds up the process on devices with a long history of correspondence.

When installing third-party software, be sure to check the permissions. To work with messages, the application will need access to SMS and contacts. Download only trusted apps with high ratings to avoid leaking personal data. Some utilities offer a “Smart Delete” function, which automatically deletes spam and promotional messages.

A feature of such apps is the ability to filter. You can configure the deletion of only those messages that contain certain keywords, or clear correspondence only from specific senders. This is useful if you want to remove spam but keep private conversations.

⚠️ Warning: Third-party applications may request excessive access rights. Carefully read the privacy policy before installing software for working with personal messages.

Why do some applications not see all SMS?

In new versions of Android (11 and higher), access to the message database is limited for security purposes. Third-party applications can only see those SMS that came after their installation, unless special rights are granted through ADB or developer settings.

Radical method: Factory reset

If your goal is to completely prepare the phone for sale or get rid of absolutely all data, including messages, contacts and photos, then the only guaranteed solution is Hard Reset. This method returns the device Xiaomi Redmi to its out-of-the-box state. All user data will be permanently deleted.

Safety of contacts Saved Deleted completely
Safety of photos/videos Saved Deleted completely
SMS deletion Selective or bulk Full (database is reset)

adb shell content delete --uri content://sms/

⚠️ Warning: Using ADB commands requires precision. An error in syntax can result in the wrong data being deleted or the system malfunctioning. Do this only if you understand the commands.

This method works instantly, regardless of the number of messages - be it 100 or 100,000. After executing the command, the SMS database will be empty and the Messages application will show a blank screen.

Frequent questions and problems when deleting

During the cleaning process, users often encounter nuances that are not obvious at first glance. For example, messages may not be deleted due to a full trash bin or cloud synchronization. It is also important to distinguish between deleting from an application and physically erasing data from the memory chip.

This will not affect the rest of the conversations in the list.

Does the number of SMS messages affect the speed of the phone?
