Xiaomi’s current MIUI and HyperOS smartphones have a huge amount of internal memory, but the phonebook database is often filled with unnecessary entries. Over time, duplicates, old call center numbers, and contacts from already inactive social networks accumulate in the call list, which not only interferes with visual search, but can also slow down the Phone app when synchronized.
The cleaning process may vary depending on where your data is stored: in the device’s internal memory, on the device’s internal storage. SIM-Understanding the source of the record is critical, because deleting a number from one storage doesn't always affect the rest of the copies. In this article, we'll go into detail all the possible scenarios for cleaning the phone book.
We'll look at the system's regular tools, mass removal techniques and ways to deal with intrusive duplicates that often occur after moving from another Android device or iPhone. Properly organizing a call list is not just aesthetics, but the security of your personal data.
Basic removal of individual numbers through the Phone application
The easiest way to get rid of one or more unnecessary numbers is to use the standard Phone app, which is pre-installed on all Xiaomi smartphones, a method that is suitable for quick “point” cleaning, when you need to remove a specific contact immediately after a call or message.
To start, open the app and go to the Contacts tab (usually the icon of a man or address book at the bottom of the screen). Find the entry you want in the list and click on it to open the detailed card. In the upper right corner or at the bottom of the screen, you will see a three-dot menu icon or a “More” button.
In the menu that opens, select Delete. The system will immediately request confirmation of action to prevent accidental data loss. Once you click OK or Delete, the entry will disappear from the list. If the number has been synced with your Google account, it will also be deleted from the cloud if you have an Internet connection.
⚠️ Note: When you delete a contact from the Phone app, it only erases from the current list of displays. If you have multiple accounts sync enabled, check which source is selected by the filter so that you do not delete data from corporate or personal emails.
There is also the ability to quickly delete via long pressing, in some versions of MIUI, a long touch of the name in the shared list opens the context menu, where the delete point is immediately available, which saves time if you do not need to open the full subscriber card.
Mass removal of contacts in the Contacts app
When you have to clear a phone book of tens or hundreds of records, it becomes inefficient to delete them one by one. Xiaomi has a special application called Contacts (different from the Phone application in terms of advanced database management), which allows you to select groups of records and apply operations to them.
Run the Contacts app and find the Manage button (sometimes marked with a human plus-plus icon or just text) in the menu that opens, select the option to Clear Duplicates or Delete Contacts, SIM-card.
Then there's the selection process. You can tick individual records or use the "Select All" feature at the top of the screen. After selecting the desired dataset, click the "Delete" button at the bottom of the screen. The operation takes a few seconds, even if you select several thousand records.
☑️ Checking before mass removal
- 📱 Open the Contacts app (yellow or blue icon with address book).
- 🗑️ Click on the control menu and select Multiple Choice Mode.
- ✅ Check all unnecessary entries or use the “Select All” function».
- 🚫 Confirm the deletion and wait for the synchronization process to complete.
It's important to understand that mass deletion is an irreversible operation for a local copy of a database, and if you accidentally singled out an extra one, you can only restore contacts through a backup or a cloud service if it was set up in advance, so being mindful of allocating groups is a key success factor.
Working with duplicates and combining records
A common problem with Xiaomi users is the appearance of duplicate contacts, which occurs when the same number is stored in different sources: for example, one copy lies on the same page. SIM-The other one is in the phone's memory, and the third one is pulled up from WhatsApp or Telegram, and the system sees them as different objects, although it's the same person for the user.
Modern versions of HyperOS and MIUI have a smart take-and-take algorithm built in, so to use it, go to the Contacts app, click on the menu (three dots) and select Tools or Contact Management, and there will be a "Combine Duplicate Contacts" option.
The system will analyze the database and suggest pairs or groups of records with the same names or phone numbers, you can combine them manually, confirming each action, or start an automatic merger, as a result, all the numbers and additional data (email, addresses) will be collected in one card, and the extra copies will be deleted.
Why do duplicates arise?
If the automatic search fails, you can use third-party crawler apps, but regular funds are usually enough. After combining, it is recommended to check the result by opening the “joint” contact card: it should display all the associated numbers under one name.
| Type of operation | Where it's done | Impact on the cloud | Risk of data loss |
|---|---|---|---|
| Deletion of one number | Phone appendix | Synchronizes | Low. |
| Mass removal | Annex “Contacts” | Synchronizes | Medium. |
| Combination of takes | Contact tools | Changes the structure | Low. |
| Cleanup SIM-map | Contact settings | It doesn't. | Tall (no backup) |
Clearing contacts with SIM-map
SIM-The card is a relic of the past in terms of storing contacts, but many users still hold important numbers there or copy them there “just in case.” The SIM memory is limited, and it does not support long names or additional fields, which often leads to “porridge” of names and numbers.
To remove the numbers directly from SIM-maps on Xiaomi, open the Contacts app, click on the menu (three dots or stripes) and select Settings. In the list of options, find the item "Import and export contacts».
In the menu that opens, select the option “Delete contacts with the SIM-maps” or “Management SIM-The system will show you a list of all the records stored on the chip, highlight the unnecessary (or all at once) and confirm the deletion. Note that after that the numbers will physically disappear from the plastic card.
⚠️ Note: Removal of contacts with SIM-The card does not affect copies that may already be copied to the phone's memory. If you have previously imported, there will be twins left in the phone that need to be removed separately through mass allocation.
Recommended after cleaning SIM-Maps immediately copy the remaining important numbers to your phone or Google account» -> «S SIM-map» -> «This will ensure the safety of data even if the device is lost or broken.
Delete via Google and Mi Cloud account
Synchronization is convenient, but it works both ways. If you delete a contact on your phone, it will disappear in the cloud. However, if you need to clean your phone book remotely (for example, your phone is lost or you want to do it from your computer), you can use the web interface.
For users of the Google ecosystem, you need to access contacts.google.com from any device. Sign in with the same account as your Xiaomi smartphone. You can select contacts, group them and delete them in the interface. Changes will automatically apply to your phone the next time you connect to the network.
So, the Mi Cloud, too, goes to i.mi.com, select Contacts, and you can not only delete your records, but you can also recover them from a cart that stores deleted data for 30 days, which is a great error insurance.
When working with the cloud, it is important to monitor the sync status. If the phone is on Wi-Fi Only mode for sync and you have deleted the contact via mobile Internet, the changes may not apply immediately.
Recovery of remote contacts and work with the basket
Accidentally removing an important number is a bad situation, but Xiaomi and Android have rollback mechanisms, and it’s worth checking the Recycle Bin in the Contacts app or the web version of Google Contacts first.
In the Contacts app on Xiaomi, go to the settings and find Restore Contacts or Recycle Bin (location depends on the version of MIUI), where you store deleted records from the last 30 days. Just select the ones you want and click Restore.
If your phone doesn't have recovery, go to the Google Contacts web version. On the left menu, look for the Recycle Bin. Google stores deleted contacts for up to 30 days. Highlight the ones you want and press the Restore button. Then turn on sync on your phone and the numbers will go back to the list.
💡
Set up automatic backup once a week in your Google account settings to always have a rollback point in case the entire phone book is accidentally deleted.
For a deeper recovery (if more than 30 days have passed), you can use the Undo Changes feature in Google Contacts, which allows you to roll back the state of the entire database to a specific time (for example, “yesterday” or “a week ago”).
