How to remove multiple contacts on Xiaomi Redmi 9C: all working ways

Removing unwanted contacts on Xiaomi Redmi 9C one by one is time-consuming, especially if hundreds of them have accumulated: duplicates after syncing with social networks, old colleagues’ numbers or advertising entries from stores. Unfortunately, Xiaomi’s standard Contacts app does not offer built-in mass removal functionality – but that does not mean that the task is impossible.

In this article, we’ll look at 5 proven ways to delete multiple contacts on Redmi 9C without a routine click on each individual. From built-in Google Contacts tools to customized apps, choose a method to suit your needs, and how to avoid accidentally deleting important records and restore contacts if something goes wrong.

Method 1: Mass Deletion via Google Contacts (the most reliable method)

If your contacts are synced to your Google account (and on Xiaomi Redmi 9C this is enabled by default), the easiest way is to use the web version of Google Contacts.This method does not require installing additional programs and works even on a weak Internet.

Here's how to do it:

• 🌐 Open your browser on your computer or phone and go to contacts.google.com. Sign in with the same account as Redmi. 9C.
• 🔍 In the upper left corner, click on the search box and type * (asterisk) – this will display all contacts without filtering.
• ✅ Check the box next to the unnecessary entries. To select all, click on the "Select All" icon (the box with the tick at the top of the list).
• 🗑️ Click on the basket icon ("Delete") in the top panel. Confirm the action.

⚠️ Attention: Remote contacts enter the Google Recycle Bin and are stored there for 30 days. To restore them, open the Recycle Bin section on the left menu and select Restore.

Sync your contacts with Google (Settings → Accounts → Google → Contact Sync)

Check the backup (Settings → Google → Backup)

Filter contacts by labels (such as “Work” or “Friends”) to avoid removing important contacts.

Use keyword searches (such as “store” or “delivery”) to dot removal.-->

The advantage of this method is that deletion occurs on all devices associated with a Google account, including Redmi 9C, tablets and other smartphones.

Method 2: Use the Xiaomi Contacts app (limited functionality)

The standard Contacts app on Xiaomi Redmi 9C (MIUI 12 and later) doesn’t support mass removal directly, but there’s a workaround through duplicates and manual filtering, which is fine if you only want to delete duplicate records.

Instructions:

1. Open the Contacts app on Redmi 9C.

⚠️ Warning: This method only works for duplicates, and if you want to remove unique contacts (like old store numbers), it's useless. MIUI Combine and fix may not be available – it depends on the regional firmware.

I only use the standard "Contact" app.

I sync with Google and manage via the web version

I install third-party applications (e.g. Truecaller)

I do not manage – I remove it as needed.-->

Method 3: Third-party applications for mass removal

If the built-in tools don’t fit, specialized applications will come to the rescue, such as Contacts Optimizer or Simpler Merge, which allows you to delete contacts in groups according to specified criteria (for example, all entries without names or with the same numbers).

Recommended app: Contacts Optimizer (available on Google Play)

• 🔍 Filtering contacts by name, number, labels and even by source (SIM, Google, phone).
• 🗑️ Mass removal of selected groups with one tap.
• 🔄 Opportunity to cancel (if you delete something important).
• 📊 Statistics on duplicates and blank records.

Instructions for use:

1. Install Contacts Optimizer from Google Play.
2. Open the app and give access to contacts.
3. In the Cleanup section, select Duplicate Contacts or Empty Contacts (depending on the task).
4. Check the unneeded entries and click Delete Selected.

⚠️ Note: Before mass removal through third-party apps, back up your contacts. Some programs (such as Simpler Merge) can delete records without recovery if you don't sync with Google.

💡

Before installing a third-party contact app, check reviews and rankings on Google Play. Avoid programs with suspiciously broad resolutions (such as SMS or geolocation access).

Method 4: Export and import of contacts through VCF-File (for experienced users)

This is a method that's good for people who are willing to do a little bit of tinkering with files, and the idea is to export all contacts to a.vcf file, edit it (deleting unnecessary entries), and then import it back, which requires precision, but gives you complete control over the process.

Step-by-step:

1. Export Contacts: Open Contacts → ⋮ → Contact management → Imports/Exports → Export to the device. Select all contacts and save the file (usually called contacts.vcf).
2. Edit the file: Copy contacts.vcf to your computer. Open it in a text editor (like Notepad++ or VS Code). Delete BEGIN:VCARD...END:VCARD blocks for unnecessary contacts.
3. Import back: Copy the edited file back to Redmi 9C. In Contacts, select Import/Export → Import from the device and specify the file.

⚠️ Note: When editing a.vcf file, do not delete service lines (e.g, VERSION:3.0 or PRODID:-//Google Inc//). Syntax error can cause loss of all contacts when importing!

This is ideal if you want to delete contacts according to complex criteria (for example, all numbers with a code of +375 or records without email), but it requires care and basic knowledge of working with text files.

Method 5: Removal of contacts with SIM-Cards (if they are stored there)

If your contacts are saved to SIM-card (which is rare for modern smartphones, but sometimes occurs), they can be deleted in groups directly through the settings of Redmi 9C. Keep in mind that SIM-Maps usually support no more than 250 contacts, and editing them is less convenient than in the cloud.

How to delete:

1. Open Contacts. → ⋮ → Contact management → Copy/Delete Contacts SIM.
2. Choose Delete with SIM.
3. Check the unneeded entries or click Allocate.
4. Confirm removal.

⚠️ Attention: Contacts to SIM-The maps are not synced to Google and are not backed up automatically. If you delete them incorrectly, you can't recover them without specialized services (which don't always work).

💡

Before removing contacts with SIM-Make sure to copy the cards to your phone memory or Google Account. To do this, select Copy with the Contact Management menu. SIM phone-on.

What to do if your contacts are deleted by accident?

Even with a neat removal, there is a risk of losing important numbers. Fortunately, there are several ways to recover on the Xiaomi Redmi 9C:

• 🔄 Google Contacts Recycle Bin: If contacts have been synced to Google, go to contacts.google.com, open the Recycle Bin section (left) and restore the required entries within 30 days.
• 📱 Local Backup: Check if backup is included in Settings → Google → Backup. If yes, try resetting your phone to factory settings and recovering data from the backup.
• 💾 Third-party programs: Apps like Undeleter or DiskDigger can scan a phone's memory for deleted.vcf files. Success depends on how long it's been since you deleted it.

⚠️ Note: If you used a third-party cleanup application (e.g. Clean Master), they could delete contacts irrevocably by overwriting the data.

To avoid future losses:

• 🔗 Enable automatic sync with Google (Settings) → Accounts. → Google → Synchronization of contacts).
• 📅 Export contacts to.vcf file regularly (once a month) and save them to the cloud (Google Drive, Yandex.Disk).
• 🚫 Avoid memory cleaners that promise to “optimize contacts” – they often delete data without warning.
