Modern Xiaomi and Redmi smartphones are equipped with powerful tools for recording phone conversations that are built directly into the system call. This feature is incredibly convenient for storing important information, agreements or instructions, but over time, the accumulated array of audio files can significantly load the internal memory of the device. Users often face a situation where notifications about the lack of space appear precisely because of the “heavy” audio archives that lie in the folders by default for years.
The process of cleaning this data is not always obvious, especially given the constant changes in the MIUI shell and the transition to HyperOS. In different versions of the firmware, the paths to files and application names may differ, which causes confusion among gadget owners. In this article, we will discuss all the available ways to delete records, from standard system tools to work with the file manager and cloud storage.
Before you start permanently deleting, make sure that there are no really important things that you might need in the future among the hundreds of files, and we’ll look at how to safely free up space without removing the extra, and how to set up automatic cleanups so that the memory problem doesn’t reoccur. Understanding the storage structure in Xiaomi’s ecosystem will allow you to manage content as efficiently as possible.
Standard Call Application and History Management
The easiest and fastest way to delete a particular recorded conversation is to do so directly through the call log. The standard Phone app, which is part of the system, stores not only the history of the numbers, but also the audio files associated with them. When you delete the record from this interface, you are working with a specific event, which minimizes the risk of error.
To start, open the Phone app and go to the History or Recent tab. Find the contact or number you want, which usually displays a small voice recorder or tape recorder icon indicating that you have a record. Clicking on this icon or swipe on the call card will open a detailed menu where the deletion button for a particular file is located.
If you have to delete multiple records associated with a particular subscriber, it's more convenient to use the mass selection feature, in some versions of MIUI, clicking on a number in history long enough to activate the allocation mode, then you can tag all the calls you're interested in and clear them in one action, which saves you a lot of time when you clean up the archives.
⚠️ Attention: Deleting the call log record often only deletes the audio file, but the phone number and the time of the call remain in the history.
Importantly, the interface may vary slightly depending on the regional firmware version (Global, China, EEA). In Chinese versions, the call functionality is often richer, but there may be no automatic transcription or cloud synchronization available in global builds. So the location of the buttons may vary, but the logic of the operation remains the same for all devices of the brand.
Working with the Dictaphone application and archive of records
A separate Dictaphone app (or Mi Dictaphone) serves as the central repository for all audio recordings, including those taken during phone conversations, if the appropriate save option is selected in the settings, which allows you not only to listen, but also edit, cutting unnecessary pauses or noisy areas before deleting.
Inside the app, all files are usually sorted by date or divided into categories such as Conversations, Interviews or Notes. To delete recorded conversations, go to the appropriate folder, click on the menu icon (three dots or stripes) and select the Delete option. The system will suggest you select files manually or use the Select All feature for total cleanup.
One of the useful features is batch processing. You can sort records by size or date to quickly find the oldest or "heavy" files that take up the most space. Once you single out a group of files, confirm the action and they will be moved to the bin, from where they can be recovered within 30 days.
- 🗑️ Single Deletion: Swipe left on a specific file in the list will quickly send it to the basket without further confirmation.
- 📂 Sorting: Use a filter by record type (incoming/outgoing) to avoid removing important outgoing instructions.
- 🔄 Recovery: Files in the Recycle Bin take up space on the disk, so remember to clean the Recycle Bin itself after you delete it.
It's worth mentioning that the Voice Recorder app on Xiaomi often has a built-in speech recognition feature that creates a text version of a conversation. When you delete an audio file, the text transcription is also deleted, but if you save the text separately in notes, it will remain accessible, an important nuance for those who conduct business correspondence based on verbal agreements.
💡
Before you massively delete old conversations, export the most important ones to your computer or cloud, as recovery from the cart after 30 days becomes impossible.
Search and delete files through Explorer
For users who prefer full control of the file system, standard Explorer will be an indispensable tool, which allows you to find and delete records even if they do not appear in standard applications due to software failures or indexing errors.
The default conversation records in Xiaomi devices are stored in a specific internal memory directory, and the path to that is usually as follows: MIUI/sound_recorder/call_rec. After going through the file manager, you will see a list of all saved audio files in the format.m4a or.mp3.
Using Explorer, you can sort files not only by date but also by size, which is extremely convenient for finding hidden memory eaters. Sometimes, a folder can get stuck with corrupted zero-sized files or duplicates that are not visible in the call interface. Direct deletion through Explorer ensures that the file is physically erased.
/storage/emulated/0/MIUI/sound_recorder/call_rec/If you can't find the folder call_rec, Try looking for the file extension. Type in the explorer's search bar.m4a or.mp3, And the system will display all the audio files on the device, so be careful when you delete them through search, so that you don't accidentally erase the music or podcasts that you've saved in other folders.
☑️ Check before deleting files
Cleaning through storage settings and memory analysis
Android’s MIUI-based system provides powerful tools for analyzing space. In the Settings section, Advanced Settings → Memory (or simply Storage) you can see the details of which data categories are taking place on your Xiaomi.
Often, conversation records are classified by the system as "Audio" or "Other," and by clicking on these categories, you can go to a list of files that are sorted by size, which allows you to quickly identify anomalies, for example, if one record of a conversation weighs several gigabytes due to an encoder error, and delete it.
Newer versions of the HyperOS shell have an improved cleaning tool that automatically finds long videos and audio files that haven't been opened in a long time.The system can suggest removing recordings of conversations older than 6 months or a year, which is a great way to prevent cleaning without manual sorting.
| Cleaning method | Difficulty | Security | Efficiency |
|---|---|---|---|
| Through the call log | Low. | Tall. | Medium |
| Through the Dictaphone app | Low. | Tall. | Tall. |
| Through the Conductor | Medium | Medium | Maximum |
| Cleaning the vault | Low. | Tall. | Medium |
Using a built-in memory analyzer also helps to understand what percentage of the total volume is voice recordings. If this figure exceeds 5-10%, regular cleaning will be a necessity for stable operation of the smartphone, as a crowded system partition can cause interface lags.
Delete records from the Mi Cloud and Google Photos
Many Xiaomi users use the Mi Cloud cloud service to sync data. If you have voice recorder sync enabled, deleting a file on your phone can automatically remove it from the cloud, freeing up space in your account, but it is important to check your sync settings before you start cleaning.
To manage your cloud copy, go to Settings → Mi → Mi Cloud → Recorder. You can see a list of all downloaded records. Deleting from here will free up your cloud storage quota, which is especially true for free 5GB tariffs.
It’s also worth checking out the Google Photos app if you have Download and Sync enabled for audio files. While Google Photos mostly works with images and videos, some audio recordings may fall into the Library → Files on your device section. Deletion from there also requires confirmation, as the file can be deleted from the device.
⚠️ Note: When you delete files from the Mi Cloud via the web interface on your computer, the changes sync with all connected devices.
If you use third-party cloud services like Google Drive or Dropbox, check your autoload folders. Often users set up an automatic backup of the Recordings folder, and old files continue to take up space already online, even if deleted from your phone.
What to do if the file is not deleted?
Set up automatic cleaning and prevent overflow
To prevent the memory overflow problem from returning, it is advisable to set up automatic deletion of old records. The Recorder app has hidden or non-obvious settings to limit the number of files stored or their total weight.
Go to the voice recorder settings (usually through a gear or three dots in the corner) and find Size Limit or Autodelete. You can set a limit, such as storing only the last 100 records or deleting files older than 3 months, which provides a balance between saving history and free space.
It is also recommended to change the format of the recording to a more compact one, if the quality is not critical.Switching from WAV to MP3 or AAC (M4A) format can reduce the file size by 5-10 times without significant loss of speech intelligibility, this is especially true for recording long lectures or meetings.
- 📉 Storage limit: Set a 500MB limit for the conversation folder so that the system can control the volume of the conversation.
- 🗓️ Time filter: Set up automatic file cleanup over 90 days.
- 📡 Wi-Fi only: If you sync recordings, enable Wi-Fi-only downloads so you don’t waste mobile traffic.
Regular memory monitoring is a good habit for any Xiaomi owner. 2 file-checking call_rec, Your smartphone will work fast, and important conversations will not be lost in a sea of audio noise.
💡
Automatically adjusting the storage limit in the Dictaphone application is the most effective way to forget about the problem of memory shortage due to conversation records.
