Modern Xiaomi smartphones, which are based on the shell MIUI or HyperOS, accumulate a huge amount of data during operation. One of the most invisible but significant parts of this digital baggage is text messages and multimedia files attached to them. Over time, the SMS database can grow to hundreds of megabytes, which not only makes it difficult to find the necessary information, but also indirectly affects the speed of the system when working with the relevant applications.
Users often need to free up space or simply clean up correspondence by deleting old dialogs. However, depending on the firmware version and device model, the algorithms for action may vary slightly. In this article, we will detail all the ways to clean up the history of messages, from standard methods to advanced memory management tools.
It is important to understand that deleting messages is irreversible without prior backup. The Messages app on Android does not have a built-in shopping cart where deleted records can be temporarily placed. So before starting a mass cleanup, make sure that there is no critical information among the data being deleted, such as confirmation codes or important addresses.
Delete individual messages and entire dialogues
The most basic and common method of clearing history is manual deletion through the application interface, which is ideal when you need to get rid of specific emails or correspondence with a particular contact. The interface may vary depending on whether you use a standard Google app or a system application MI Messaging, but the logic of actions remains similar.
To delete an individual message, you need to open the desired dialog and find the desired email. Most shell versions require a long press on the text of the message, after which it will stand out, and at the top of the screen will appear a context menu. Here you can select the deletion option, often indicated by the garbage bin icon or the Delete icon.
If you want to delete the entire email branch, the algorithm changes, you need to make a long-term click on the contact name or phone number on the main list of all the dialogs, and after you select the dialog (it will be illuminated by color) in the top dashboard, you can delete the entire history of communication with this subscriber in one action.
β οΈ Note: When you delete the dialog, the entire history of the correspondence with this contact is erased. It will not be possible to restore it with standard system tools, so double check whether the contact you chose is the one you have chosen.
Some firmware versions allow you to allocate multiple dialogs simultaneously for batch removal, so after selecting the first dialog, simply tap other contacts in the list without letting your finger go or using the "Select All" function in the control menu, which significantly speeds up the cleaning process with a large number of incoming notifications and spam.
Mass cleaning through storage settings
When manual removal becomes too time-consuming due to the sheer number of messages accumulated, Xiaomi's built-in system optimization tools come to the rescue. MIUI HyperOS has powerful built-in memory management functionality that allows you to find and delete large amounts of data, including SMS-message.
To access these features, you need to go to the Settings menu and select About Phone or immediately open the Security app, which is preinstalled on all devices of the brand. Inside the Cleanup or Storage section, the system will analyze the data and prompt you to delete unnecessary files. Often messages are categorized as "large files" or "old messages".
Messages can also have its own memory management menu, which is usually available through a three-dot menu in the upper right corner or in the Settings section of the app itself, and you can find Delete old messages where the system will prompt you to delete all emails older than a certain period (for example, 3 months or a year).
βοΈ Checklist before mass cleaning
Using system cleaners is preferable to third-party applications, as they have deep access to the file system and do not require additional permissions that could jeopardize your security. In addition, Xiaomi system utilities know better the structure of the sqlite database where messages are stored and work more consistently.
Multimedia Investments (MMS)
Multimedia messages, or MMS, are worth special attention. Unlike regular text, they occupy a significant amount of internal memory of the device. Photos, videos and audio recordings received through SMS are stored in special folders and can weigh tens of megabytes each.
To remove the multimedia content, you donβt have to delete the text message itself. In the Xiaomi gallery or in the Files app (Conductor), you can find the MMS or SavedMMS folder. The path to it usually looks like Internal Memory β DCIM β MMS or Internal Memory β MIUI β gallery β cloud β albums β MMS.
Deleting files from these directories will free up space, but the attachment icon may remain in the Message application itself, although you will not be able to open the file. For complete cleaning, you should use the Cleanup function in the message application settings, where you can sort dialogs by attachment.
| Type of data | Approximate size | Where it takes place | Difficulty in removal |
|---|---|---|---|
| Textual SMS | < 1 KB | System database | Low. |
| Photo (MMS) | 500 KB - 5 MB | Memory of the device / Gallery | Medium |
| Video (MMS) | 5MB - 50MB | Memory of the device / Gallery | Medium |
| Group chat rooms | Depends on the content. | Database + Memory | Tall. |
It is worth noting that today's carriers rarely use classic MMS, preferring to transfer media over Internet messengers. However, on older devices or in the absence of the Internet, MMS can still come and take up space. Regularly checking the download folder will help keep the storage clean.
Why are deleted messages taking up space?
Use of third-party applications to manage SMS
If Xiaomiβs standard functionality isnβt enough, the Google Play store offers a variety of custom messaging apps, and utilities like SMS Organizer or Googleβs Messages offer advanced filtering, archiving, and deletion capabilities.
One of the main advantages of third-party apps is that they can sort messages into categories: personal, transactional, promotions, which allows you to quickly identify and remove all spam or promotional mailings without affecting important correspondence. Some applications have a Smart Cleanup feature that itself offers to delete messages from delivery services or banks over a certain date.
But installing third-party software requires advanced permissions, and the app needs access not only to read, but also to manage SMS, which could theoretically be used by attackers to intercept confirmation codes, so only choose proven solutions with high ratings and a large number of users.
β οΈ Warning: Avoid installing apps with a name "SMS Cleaner, which requires internet access to "analyze" your messages, is a direct route to identity theft, only use offline tools or proven launchers.
Third-party apps also often allow you to export messages to CSV or PDF format before deleting, a useful feature for those who need to save legally significant correspondence or simply archive important conversations before clearing the phone's memory.
Recovery of Accidentally Deleted Messages
It is very common for a user to delete an important message by mistake. Unfortunately, as mentioned, Android does not have a global SMS shopping cart. However, there are ways to try to get back the data if you have taken care of the backup beforehand.
The most reliable method is to use the Google One cloud service or the Xiaomi Cloud built-in sync. If you have SMS sync enabled, you can restore them when you reset your phone settings or log in to your account on a new device. In the Google account settings (Settings β Google β Backup), you can check the date of the last saved copy.
To recover data without resetting the system, there are special programs for PCs, such as Dr.Fone or PhoneRescue, which scan the internal memory of a device for deleted fragments of the database, and the effectiveness of such programs depends on how much memory was overwritten after deletion.

Turn on SMS sync with Google Drive right now. This will take a couple of minutes, but it could save your nervous system in the future. Way: Settings β Google β Backup β Enable.
It's important to understand that if messages have been deleted long ago and the phone has been actively used, the probability of recovery is close to zero, new data is physically written on top of remote memory sectors, so the only guaranteed way to save messages is to regularly back up to an external medium or to the cloud.
