Modern Xiaomi smartphones accumulate huge amounts of data, and among them SMS-Messages are not the last place, especially if you actively use them to confirm transactions or receive codes from services. Over time, a crowded inbox begins to interfere with navigation, and confidential information left unattended can become a target for attackers who gain access to the unlocked screen. That is why the question of how to effectively and safely remove messages on Xiaomi becomes relevant for every owner of a device running a shell. MIUI or hyperos.
In this article, we will discuss in detail all available cleaning methods: from the banal removal of one dialog to the complete reset of the database through the engineering menu or ADB. You will learn how to recover accidentally deleted SMS if necessary, and what nuances should be considered when working with Xiaomi system applications. Data security is a priority, so we will pay special attention to methods that ensure that information cannot be restored.
MIUI interfaces may vary depending on the Android version and regional firmware, but the basic principles of messaging remain the same.We will look at both the standard tools built into MIUI Messages and more advanced ways for power users. Follow the instructions carefully so that you do not lose important confirmation codes or passwords that may be required in the future.
Basic removal of dialogs in the Messages annex
The easiest and most obvious way to get rid of unnecessary correspondence is to use the regular functionality of the application. In the standard Messages application from Xiaomi (or Google Messages, if you changed the application by default), the cleaning process is intuitive, but has its own peculiarities depending on the selected viewing mode.
To delete one or more dialogs, you need to open the application and find the contact you want in the shared list. A long click on the message icon activates the selection mode, after which the toolbar appears on the top, and you can tick several dialogs that you want to eliminate, and click the delete button, usually represented by the basket icon.
⚠️ Note: When you delete the dialog through the standard menu, all messages within this chain are permanently erased from the main storage of the phone, unless cloud sync or backup is enabled.
If you want to delete a particular message inside a correspondence, rather than the entire dialogue, the algorithm changes a little: Open the chat, press and hold your finger on the text of a particular SMS, select it (or several) and press the delete button. The system can request confirmation of action to prevent accidental loss of data.
Importantly, newer versions of MIUI and HyperOS may delete via a context menu called by a swipe, and try swiping a finger from left to right or right to left, often opening up hidden options, including quick deletion or archiving.
Mass cleaning and storage management
When you count hundreds or thousands of messages, it becomes inefficient to delete them in one or even in groups of 5-10 messages, and in such cases, the mass cleaning functions built into Xiaomi system utilities or available through the message menu itself come to the rescue.
Messages often has a built-in settings or management menu where you can find the option to "Clean All" or "Delete Old Messages." Accessing these features often requires you to click three dots in the corner of the screen or go to the app settings, where you can set a limit on the number of messages saved for each contact or delete all messages over a certain date.
- 📱 Open the Messages app settings (three dots or gears).
- 🗑️ Find the "Additional" or "Message Management" item".
- 📅 Select the option “Delete old messages” and set a time interval.
- ✅ Confirm the action, knowing that recovery will be impossible.
Another powerful tool to free up space is the built-in Security app, which is pre-installed on all Xiaomi smartphones.In the Cleanup section, the system analyzes the contents of the phone and can suggest removing old or large files, including MMS attachments and text messages that take up a lot of space.
☑️ Checklist before mass cleaning
Using system cleaners is safe because they work within Android permissions and do not require superuser rights, but it is always worthwhile to double-check the list of files marked for deletion so as not to accidentally erase something critical, such as an SMS with a code from a bank that you have not yet used.
Using Mi Cloud and Synchronization
Xiaomi’s ecosystem offers a handy Mi Cloud service that not only stores data backups, but also manages them remotely. If you have message synchronization enabled, you can manage them via a web interface or cloud settings on another device.
To delete messages through the cloud, you need to log into your Mi Account on i.mi.com or through your phone settings. In the Messages section, you will see a list of synchronized dialogs. Deleting the message here will cause it to disappear on all devices associated with this account2un, including your smartphone.
| Action. | Where it's done | The result |
|---|---|---|
| Deletion on the phone | Annex Communications | SMS disappears from the device, in the cloud may remain a copy |
| Removal in Mi Cloud | Website i.mi.com / Settings | SMS is removed from the cloud and synced to the phone |
| Shutting down synchronization | Settings for Mi Account | Stops updating, but does not delete old data |
It's important to distinguish between local and cloud removal, and if your goal is to make room on your phone but save your history, you'd better use the archiving or porting function to your PC instead of the full deletion function, and backup is your best friend in these situations.
⚠️ Note: Deleting messages from Mi Cloud via the web interface is often final and does not allow data to be recovered through the standard shopping cart, unlike deleting directly on the device.
Also, it's worth remembering that synchronization only works when the Internet is turned on. If you delete a message on your phone in flight mode, it will disappear locally, but the next time you connect to the network can be restored from the cloud if the synchronization is active.
Advanced Methods: ADB and Root Rights
For users who want to gain maximum control over their device or automate the cleaning process, there are methods that require a connection to a computer. Using USB debugging (ADB) allows you to send commands directly to the Android system, bypassing the graphical interface.
Before you start, you need to activate the developer mode. To do this, go to Settings → About Phone and quickly click on the build number seven times (MIUI Version). Then, in advanced settings, turn on "Debugging over USB." Connect the phone to your PC and use the command to delete the SMS database.
adb shell pm clear com.android.mmsThis command completely cleans the data of the message application, which is equivalent to deleting all SMS and MMS. Be very careful, because this action is irreversible through standard means of recovery. SQL-database queries if the device has Root rights, but this requires a deep knowledge of the Android file system.
Risks of using ADB for beginners
Users with superuser rights (Root) can directly edit or delete database files that are usually located on the path /data/data/com.android.mms/databases/mmssms.db. Direct deletion of this file will lead to a complete clearing of the message history. However, modern versions of Android and the MIUI shells actively resist such interventions, requiring the bootloader to be unlocked.
Recovery of deleted messages
It is not uncommon for a user to delete an important message by mistake or in a hurry. Fortunately, there are several ways in the Android and MIUI ecosystem to try to recover lost information, although success is not 100% guaranteed.
The first place to look for missing SMS is the shopping cart in the messaging application itself, if this is provided by the MIUI version. In some shell modifications, deleted messages are temporarily moved to an archive or a special folder, where they are stored for 30 days before final deletion. Check the application settings for the presence of the item "Basket" or "Recently deleted".
- 🔄 Check backup in Mi Cloud or Google Drive.
- 📂 Look into the Archive folder inside the Messages app.
- 💻 If you synced with a PC, check notification history or emulator programs.
- 🛠️ Use specialized data recovery software (such as Dr.Fone) but with caution.
If you had Google Drive enabled and you selected SMS backup, you can try to restore data when you reset your phone to factory settings. When you initially set up Android, the system will offer to restore data from the cloud. Recovery from Google Drive backup is only possible with a complete reinstallation of the system or on a new device, selective recovery of SMS without reset is not possible.
💡
To automatically save important SMS, use automated applications such as SMS Backup & Restore, which can send copies of messages to you via email or cloud storage in real time.
It should be understood that if the message was deleted long ago, and since the deletion of the phone is actively used, writing new data in memory, the chances of recovery tend to zero.
Security and privacy of correspondence
Deleting messages is not only a matter of order, but also an important part of digital hygiene. SMS often receives confirmation codes, password reset links and other sensitive information. Simply deleting a dialogue does not always guarantee that data cannot be recovered by special methods.
If you plan to sell your phone or transfer it to another person, simply deleting messages is not enough. Attackers with the appropriate equipment can recover deleted data. In such cases, it is recommended to perform a complete reset of the device (Wipe Data) and then write dummy files (unnecessary video or photo) to the entire memory volume to overwrite old sectors.
⚠️ Warning: Before selling your device, be sure to log out of all accounts (Mi Account, Google Account) and complete a full reset via the Recovery Mode menu, not just through your phone’s settings.> Also worth paying attention to the permissions that SMS applications have. Many programs require access to your messages to work, but unscrupulous developers can use this to collect data. Regularly check the list of applications with access to SMS in the Settings section → Annexes → Permits → Messages and disable access for suspicious programs. 💡Completely overwriting memory after reset is the only reliable way to ensure that deleted SMS cannot be restored when selling a device. MIUI, If you need to give your phone to someone else. This isolates your private messages and data from prying eyes without having to delete them every time (FAQ) Can you restore an SMS after a phone is reset to factory settings?

Specialized labs can try to extract data from a memory chip, but for the average user, the data is considered lost.Where are deleted messages stored on Xiaomi? In standard deletion, the message is marked as free space in the database of mmssms.db. Physically, data stays on the disk until the system writes new information on top of it, and it is stored in the basket only if this function is explicitly supported by the shell version. MIUI. How to delete SMS from a specific number if there are too many?
