Owning the popular Xiaomi Redmi Note 7 smartphone involves the use of its communication functions, which inevitably leads to the accumulation of a huge amount of data in the call log. Over time, the history of incoming and outgoing connections can number hundreds or even thousands of records, which not only makes it difficult to find the right contact, but also potentially affects the performance of the system application “Phone”. Many users face a situation where the standard interface does not allow you to delete everything at once, requiring manual selection of each position, which is extremely inefficient.
In this article, we will take a look at all the methods that exist to clean the call log, from the standard MIUI shell tools to more advanced technical solutions. You will learn how to bypass the limitations of the interface, where hidden debugging menus hide, and what nuances the Android file system has when storing call logs. Proper data cleaning is not just a cleanup, but an important aspect of the digital hygiene of your device.
It is worth considering that the procedures may differ depending on the version of the installed firmware, whether it is a global version of Global ROM or China ROM. the interface of the phone application from Google, which is often preinstalled on international versions, differs from the standard MIUI caller. So we will consider both options so that the instruction is useful to every owner of the Redmi Note 7, regardless of the region of purchase of the device.
Standard cleaning methods through the MIUI interface
The most obvious and safe way to delete your call history is in the default application, which is the MIUI group record management, but it's not always obvious to beginners. To access the advanced options, you need to open the Phone app and go to the Journal or History tab, and here you will see a list of all the connections you've made and accepted.
To start the mass cleaning, you need to press and hold your finger on any entry in the list until the highlight tick appears, and then a toolbar will appear at the bottom of the screen or in the top menu (depending on the version of MIUI), and by clicking on the "Select All" button or a similar icon with three dots, you activate the mass selection mode, which allows you to cover all available entries in the current view of the magazine at once.
However, there is a caveat: the standard menu often limits the number of entries displayed (for example, 100 or 200 last) If your history has thousands of calls, you will have to repeat the procedure several times or use alternative methods, which will be discussed below.
☑️ Manual cleaning algorithm
It is important to note that deleting records through the interface does not always instantly free up space in memory, since the system can store the cache of the call database for a while.Rebooting the device after cleaning will help the system recalculate the indexes and free up resources.
Use of the Google Phone application
Global versions of the Xiaomi Redmi Note 7 often pre-installed Google's Phone app, which has its own interface and logic. Unlike the MIUI caller, the cleaning process may look different. Open the app, go to the Recent tab. As with MIUI, long-term clicking on one of the records activates the selection mode.
In the upper right corner of the screen, you'll see an icon with three vertical dots. When you click on it, you'll see a drop-down menu where you'll have the "Select All" option available. This action will highlight all the entries you see in the current list. After that, you just have to click on the basket icon to confirm the removal. Google's interface is more minimalistic, but functionally performs the same tasks.
A feature of Google’s app is more aggressive synchronization with your account. If you have contact sync and call history enabled, deleted records on your device can be recovered from the cloud the next time you connect to the network. To avoid this, check your sync settings in the Google account section.
💡
If you use Google Phone, check your sync settings in your Google account to ensure that your deleted history is not automatically restored from the cloud.
Users often note that Google’s app is more stable when processing large amounts of data, less likely to hang around trying to highlight several hundred records at once, making it a preferred option for those who rarely clean up history and accumulate thousands of records.
Hidden Opportunities and Engineering Menu
To get a deeper look at the Redmi Note 7's call system, there are codes that allow you to access the engineering menus and test modes, and by entering ##4636## in the dialer code, you'll be taken to the Testing menu, where you can see detailed information about the phone, including usage statistics, and although there may not be a direct Clear Everything button, this menu allows you to measure the scale of the data accumulated.
A more radical but effective method is to clear the phone app itself through system settings. Go to Settings → Apps → All apps, find Phone (or Calls), and select Clear → Clear Everything. This action will reset the app’s settings and, in most cases, delete the entire call log, as it is stored in the app’s local database.
⚠️ Attention: Clearing the Phone app data through settings can cause the user to reset the call settings, such as locking unknown numbers or recording conversations.
Using ADB (Android Debug Bridge) provides another layer of control: By connecting your smartphone to your computer and activating USB debugging, you can command to directly delete records from the database if standard methods don't work, but this method requires technical skills and caution.

Synchronization and cloud services
Cloud sync plays a major role in the Xiaomi and Google ecosystem, and the call log can be duplicated in the Mi Cloud or Google Drive cloud. If you clean up the history on your phone but don't touch the cloud, the next time you turn on sync, the records can come back, so a comprehensive cleanup should also affect cloud storage.
To check your Mi Cloud settings, go to Settings → Mi Account → Xiaomi Cloud. You can manage synchronized data here. If the Call Log is enabled, its content is stored on the company’s servers. Disabling sync or deleting data from the cloud via the i.mi.com web interface ensures that the story doesn’t recover.
| Parameter | Local storage. | Mi Cloud | Google Account |
|---|---|---|---|
| Storage area | Phone memory | Xiaomi servers | Google servers |
| Speed of access | Instant. | Depends on the network. | Depends on the network. |
| Risk of loss | High on discharge | Low. | Low. |
| Impact on memory | Takes up space. | Not taking up space. | Not taking up space. |
A similar situation is seen with a Google account, which is that if you go to contacts.google.com or your Android sync settings, you can check if your call history is stored there, and in modern versions of Android, this feature is often integrated into your backup.
Automation and third-party applications
If manual cleaning seems too time-consuming, automated apps come to the rescue. There are utilities like Call Log Manager or Auto Delete Old Calls on Google Play that allow you to set up rules for automatically deleting old records, such as, “Delete calls over 30 days” or “Leave only the last 100 records.”
Using these applications requires special permissions, such as access to the call log and device administrator rights (in some cases), and once set up, the application will run in the background, periodically checking the log and removing the extra according to a given algorithm, eliminating the need to remember to clean manually.
However, be careful when choosing third-party software: some applications may contain advertising or transfer metadata about your calls to third parties, it is recommended to choose programs with high ratings and a large number of positive reviews, and read the privacy policy carefully.
💡
Automating the cleaning process is the best solution for users who want to keep their call logs in order without regular manual intervention.
Alternatives to third-party applications can be standard scripts in the Auto Tasks app (if available in your version of MIUI) or the use of macros that allow you to create your own cleaning scripts, although the functionality to work with the call base there is limited for Android security reasons.
Technical aspects and file system
Technically, the Redmi Note 7 call log is a SQLite database, and the file is usually located along the path /data/data/com.android.providers.contacts/databases/contacts2.db (the path may vary depending on the Android version and the call).
Root rights open up the possibility of using specialized file managers (such as Root Explorer or Solid Explorer with root rights) that allow you to directly edit or delete the contents of system databases. This is “heavy artillery” that is used when the call log is damaged, and standard cleaning methods cause errors or freezes of the system.
⚠️ Warning: Direct editing of system databases without a backup can cause the Phone application to fail and all contacts to be lost.Before any manipulation of files at the root of the system, be sure to create a full backup copy (TWRB analogue).
It is also worth mentioning that frequent recording and deleting of large numbers of records in a database can lead to fragmentation, and periodic complete cleaning (or resetting of an application) helps defragment the database, which can theoretically positively affect the speed of opening the application of the call.
