Cleaning the phone book on Xiaomi, Redmi or POCO devices is often required when preparing a gadget for sale, transferring to another user or when critical synchronization errors. Smartphone owners face a situation where thousands of duplicates or old records are accumulated that cannot be manually deleted in a reasonable time. The standard MIUI or HyperOS interface allows you to delete groups, but does not always provide an obvious “Delete everything” button for local records.
There are several effective ways to do this quickly and without losing important data if you do it right. The choice of the specific way depends on where your numbers are stored: in the SIM card memory, in the internal memory of the device or in the Google cloud account. In this article, we will look at all the options available, from simple settings in the menu to using specialized tools.
Before you start radical action, make sure to back up all the important numbers. Contact deletion is irreversible without a backup. Even if you plan to sell your phone, make sure your data is stored on another medium.
Preparation for deletion and backup
The first step before any mass operation is to create a restore point. In the Android ecosystem, the main storage is most often a Google account, but on Xiaomi phones, data can be duplicated in Mi Cloud. If you delete records from the cloud, they will disappear from all synchronized devices, so it is important to understand the source of the data.
To create a reliable copy, go to the Contacts app and select the management menu. You can export all records to a.vcf file. This universal format is supported by any smartphone and email client. Save the resulting file to your computer or send yourself an email to access it even after the phone is completely cleaned.
⚠️ Attention: Deleting contacts from your Google account will cause them to disappear on all devices where you log in to that account.
It is also worth checking whether the numbers are stored on the SIM-Although modern smartphones rarely use a SIM for storage due to the limited number of characters in the contact name, this possibility exists. SIM card management is carried out through a separate menu in the contact settings, where you can copy data to the phone or delete it.
☑️ Preparation for cleaning
Delete contacts via Google Contacts web interface
The fastest and most reliable way to clean a phone book on Xiaomi is to use the web version of Google Contacts, which is ideal if your numbers are synced with your Gmail account, which is enabled by default on most devices.
You need to log in to the same account that you use on your smartphone. In the interface on the left, you'll see a list of categories, like Contacts, Frequently Used, or Other Contacts. Select the right group or click on the checkbox in the top left corner to highlight all available entries.
Once you select, a pop-up menu will appear. If you have many entries, the system will prompt you to select All Contacts (e.g. 1500) rather than just those that appear on the screen. After selecting all entries, click on the basket icon or the Delete button. The changes will take effect immediately after the device is synchronized with the server.
- 📱 Open your browser and go to contacts.google.com.
- 🔑 Sign in to your Google account linked to your phone.
- ✅ Click on the selection box at the top left and select "All».
- 🗑️ Click on the basket icon and confirm the removal.
The good thing about this method is that it doesn't require any additional software to be installed, and it works even if the phone is locked or has a damaged screen, but it's all about the Internet, but if the contacts are only stored in the phone's memory ("Device") and not synchronized, they won't be affected.
💡
Use the “Cancel” function in Google Contacts within 30 days of deleting if you accidentally erase the extra. Change history is stored in the “Basket” or “Settings” section -> “Cancel changes”.
Cleaning through MIUI and HyperOS synchronization settings
The built-in MIUI shell allows you to manage contacts, and if you want to delete only local copies or break the connection to a particular account, you can use system settings, especially when you need to clean your phone of junk records from old accounts.
Go to your Xiaomi device's Settings, then go to the Apps and find Contacts. It's not just about clearing the cache, it's about managing the data. However, a deeper clean is done through the contacts themselves. Open the Contacts app, click on the three dots or gear in the corner to enter the settings.
Find Contact Management or Contact Management, where you can find the "Joint Duplicates" or "Clean" function. Some firmware versions have the option to delete contacts from a specific source. Choose the "Phone" or "Device" source to erase only the local base, not the cloud.
| Action. | Wherever | The result |
|---|---|---|
| Clear the cache | Settings → Applications → Contacts | Delete temporary files, contacts will remain |
| Clear the data | Settings → Applications → Contacts | Reset application settings, delete local records |
| Turn off sync. | Settings → Accounts → Google | End of Update, Old Records Will Remain |
| Delete the account | Settings → Accounts and Synchronization | Delete all account data from the device |
It's important to distinguish between cleaning the application data and deleting the records themselves. Cleaning the application data will return the contact menu to its original state, but if the numbers are stored in the system's database, they can be saved.
What are local contacts on Xiaomi?
Use of third-party applications for batch removal
Android's regular tools sometimes have limitations, such as not allowing you to select 5,000 contacts at a time with a single click, and in such cases, specialized tools from Google Play come to the rescue. Applications like Contacts Optimizer, Clearer, or Duplicate Contacts can analyze the database and offer mass actions.
Once you install this app, you'll need to give it permission to access contacts, and most software scans, which are duplicates, contacts without names or numbers, and then suggest that you delete them all at once, which greatly speeds up the process of cleaning up the phone book.
When using third-party software, pay attention to the permissions you request. Data security is a priority, so choose high-ranking and high-review apps. Avoid utilities that require internet access to work with contacts unless there is a clear need for cloud sync.
- 🔍 Download the proven contact management app.
- 🛡️ Provide only the necessary permissions (access to contacts).
- ⚙️ Start the scan and select the filter "All contacts».
- 🧹 Click the “Delete” or “Clean” button».
⚠️ Warning: Some cleaners may aggressively delete important system records or messenger contacts. VCF before using third-party utilities.
Radical method: Reset to factory settings
If the phone is preparing to sell or give a gift, and you need to delete not only contacts, but all other personal data, photos, apps and settings, the optimal solution is a full reset (Hard Reset), which is guaranteed to clear the internal memory of the device, returning it to the state “out of the box”.
To perform the reset, go to Settings → About Phone → Settings Reset. The system will warn you that all data will be destroyed. Make sure you know the password from your Mi Account and Google account, as after the reset, Android security may request them to confirm ownership (FRP protection).
This is the most effective way of doing this: it deletes contacts no matter where they are stored (unless they are in the cloud), and once turned on, the phone will be clean, and you will need to re-set the initial setup procedure, which is ideal for fixing software errors associated with corrupting the contact database.
💡
A complete reset is the only way to ensure that a phone buyer cannot recover your remote contacts using digital forensics.
Removal via ADB (for advanced users)
For users who are not afraid of the command line and have USB debugging enabled, there is a method of deleting through Android Debug Bridge (ADB), which allows you to directly interact with the contact database, bypassing the GUI. It is effective when the phone interface freezes due to a crowded phone book.
You'll need a computer with ADB drivers installed and a USB-connected smartphone, and after you connect and authorize debugging, you'll enter a command to clean up the contact provider, and this action instantly resets the database.
adb shell pm clear com.android.providers.contactsExecuting this command will delete all contacts stored locally on the device. If sync with Google is active, they can be restored immediately after the Internet connection appears, so it is better to disconnect the network or delete the account from the system before executing the command.
