How to delete all messages in Xiaomi Redmi 5 Plus: The Complete Guide

Redmi series smartphones, including the popular Redmi 5 Plus model, accumulate huge amounts of data over time, which can significantly slow down the device. SMS-If you’re wondering how to delete all messages in Xiaomi Redmi 5 Plus, then it’s time to clean up the system and make room for new tasks.

The cleaning process is not always obvious, as standard Android settings and MIUI shells offer different deletion scenarios: you can erase correspondence with a particular contact, remove individual threads or perform a global cleanup of the entire message database. Understanding the deletion mechanisms will help avoid accidental loss of important information and ensure the right approach to maintaining a smartphone.

In this article, we will discuss in detail all available cleaning methods. SMS-We will look at standard methods, the use of third-party applications and hidden system functions. It is important to approach this process consciously, since the recovery of remote ones is important. SMS Without a backup is almost impossible.

Preparation for deletion and backup

Before you start drastic measures and delete all correspondence, you need to make sure that critical data is safe. Often SMS stores confirmation codes from banks, two-factor authorization or important business information. Backup is a mandatory step that can not be ignored, even if you are sure that there are no important messages.

For Xiaomi owners, the easiest way to do this is to use the Mi Cloud cloud service, which allows you to sync your SMS to your Mi Account, where you can restore it at any time, and there are time-tested applications like SMS Backup & Restore that create local copies of your XML messaging database.

💡

Use the Mi Mover feature to create a full copy of your SMS to another phone or to the cloud before cleaning.

Once you have created a copy, make sure you check the integrity of the backup file, make sure the backup file is intact and readable, and then you can move on to active action to free up the memory of the device.

⚠️ Attention: Removal SMS The Android file system marks the space as free, but the physical cleanup of memory sectors can only occur after rebooting or filling in new data.

Standard removal through the Messages app

The basic way to clear your correspondence history is built into the standard Message (or Mi Messaging) application, which is pre-installed on Redmi 5 Plus. This method is suitable for selectively removing dialogs or completely cleaning if the number of threads is not in the thousands. The interface may vary slightly depending on the version of MIUI, but the logic remains the same.

To start, open the app and go to the list of all dialogs mode, where you can press a particular thread for a long time to highlight it. Once you single out one dialog, you can select others just by touching them, or select the "Select all" option in the menu. However, the mass highlighting feature of all messages may immediately be missing in some versions of the firmware.

• 📱 Open the Messages app on the main screen.
• 🔘 Press and hold your finger on one of the dialogs until the action menu appears.
• 🗑️ Select the basket icon or the “Delete” item in the top or bottom menu.
• ✅ Confirm the action in the pop-up window.

If you want to delete messages from a particular subscriber but save others, the easiest way to open the conversation is to select the history cleaner option inside the correspondence. In some versions of MIUI, the Clear All feature is available, which deletes all correspondence at once, but it requires double confirmation to avoid errors.

Use of the “Cleanup” function in the Security application

A unique feature of the MIUI shell on Xiaomi smartphones is the built-in Security app.It not only protects against viruses, but also contains powerful memory management tools, including cleaning garbage files and messages.It is one of the most effective ways to delete all messages in the Xiaomi Redmi 5 Plus quickly and safely.

Run the Security app and find the Cleaner section, and the system will automatically scan the device and find temporary files, cache and, importantly for us, old SMS. The list of items found often shows the number of messages that can be deleted, which allows you to delete the entire array of SMS without having to manually allocate them in the message application.

Unlike manual removal, the system utility works directly with the database, which speeds up the process. However, you should be careful when installing filters. Sometimes this section gets important notifications or codes that the system classifies as spam or irrelevant data.

Delete messages through storage settings

In the newer versions of Android and MIUI, application data management is made into the general system settings, which allows you to delete not only the text of messages, but also the entire cache of the application, which is useful if the Redmi 5 Plus started to work slowly from an inflated SMS database.

Go to Settings → Applications → All Apps. Find Messages in the list, and inside you’ll see the Clear Data button, which will reset the app to factory status, removing all of its correspondence, settings, and drafts.

This method is guaranteed to delete all messages, including those that may have been stuck in the system and not appear in the list, but after this procedure, the message app will look like you just turned on the phone - without history and personalized settings.

⚠️ Note: Clearing the application data through Android settings is irreversible by standard means. You can only restore correspondence from a previously created backup copy.

Use this method if standard removal doesn't work or if you're preparing your phone for sale. The previous methods are better suited for regular cleaning, as they are less radical.

Cleaning Multimedia Investments (MMS)

Often, the memory shortage problem on Xiaomi Redmi 5 Plus is not related to text messages, but to attached files. Photos, videos and audio recordings received through MMS take up significantly more space. Even if you delete the text of the message, attachments can remain in the device's memory if they were saved to the gallery or cache.

To delete this data, use the Explorer or Files app. You need to find the folder where the attachments are stored. Usually the path looks like Internal Storage/MIUI/sms/ or Internal Storage/Pictures/SMS/. It is also worth checking the Download folder, which often automatically includes files from messengers and MMS.

• 📂 Open the Files app on your smartphone.
• 🔍 Go to the Images or Video category to search for attachments.
• 🗑️ Select unnecessary files and click “Delete».
• 🧹 Don’t forget to clean the cart in the Gallery app after removal.

Automatic attachment saving can be turned off in the message app settings, find a "Save to Gallery" or similar item and deactivate it, which will prevent the accumulation of garbage in the future.

Use of third-party applications to manage SMS

If standard tools are not enough, specialized applications from the Google Play Market come to the rescue, programs like SMS Organizer or Clean Master (with caution) offer advanced functionality for managing messages, allowing you to sort SMS, classify them by category and delete them in large groups according to specified criteria.

These applications often have a Smart Clean feature that analyzes content and suggests removing promotional mailings, codes from delivery services and other unimportant messages, which is convenient because it allows you to save personal correspondence by removing all information noise.

When installing third-party software, be sure to check the permissions requested. SMS applications should only have access to messages and contacts. If the program requires access to a microphone or location without an obvious need, it is better to refrain from installing.

💡

Third-party apps are a great way to automate the process, but only trust your data to trusted developers with a good reputation.
