Preparation for deletion and data synchronization

The first step in cleaning up is to check sync status. On Xiaomi smartphones, the default contacts are saved to your Google or Mi Account. If you delete them from your phone, they can disappear from the cloud if you enable two-way sync, so the first step is to shut down the Internet or stop syncing for a particular account.

Go to Settings → Accounts and Sync. Here you will see a list of all the services connected. Select your Google account and make sure the slider opposite Contacts is off. This is a critical step that will protect your main database from accidental erasure when cleaning your device.

It is also recommended to check where the new numbers are saved. In the settings of the Contacts app, there is a paragraph "Settings» → «Saving account. If you have a phone, you have a lower risk of data loss, but you're better off being safe. Deleting contacts with the Internet down is the safest method for local cleaning without touching the cloud.

Removing contacts through a standard application

The easiest way to clean a phone book is to use the built-in Contacts app. MIUI allows you to select groups of records, which greatly speeds up the process. Open the app and go to the Contacts tab. In the upper right corner or in the menu (three dots/strips), find the edit or control button.

Click on the edit icon, which usually looks like a pencil or an "Change" sign, and you'll be able to highlight records. Often, only one contact is allocated by default, but if you click on the highlight icon (sometimes a tick in a circle or "Choose all"), you can cover the entire base, and then you'll see a delete button, often marked by a basket, after the highlight.

• 🗑️ Click "Delete" and confirm the action in the pop-up window.
• 📱 If there are too many contacts (thousands), the application can freeze, so act in portions of 500 records.
• ⚙️ In some versions MIUI There is a function “Clear duplicates” that works faster than manual removal.

It's worth noting that some firmware may not have a "Select All" button if there's more than a certain number of entries in the list, so you'll have to use the "Other" method of creating a new group, moving the contacts you want to have, and then removing the "Everybody else" group, which is less convenient but effective.

Cleaning through the Google Contacts web interface

The most effective method of total cleanup is using a browser on your computer or in full-site mode on your phone. Google Contacts provides tools that are often absent from mobile apps. This is especially true for Redmi 10, where the system is deeply integrated with Google’s ecosystem.

Go to contacts.google.com and log in with the same account you have on your phone. Make sure you're looking at the account that syncs with your device. On the left of the menu, select Contacts or Other Contacts to see the full list.

At the top of the screen is a checkbox to highlight, and clicking on it will select all the contacts you see, but if you have more than the ones on the screen (usually 50-100), you will see "Selected X from Y." Click on this link to highlight all the entries in the database.

Once you hit the delete button, the data will go to the cart, where it will be stored for 30 days. To make room on Redmi 10 instantly, you need to go to the menu on the left, select "Basket" and click "Clean the cart." Changes are automatically synchronized with your smartphone when you have the Internet.

Delete via Google Contacts’ web interface is the fastest way to clear thousands of records, but requires a mandatory shutdown of sync on your phone before you start if you want to save data in the cloud.

If your goal is to get the Xiaomi Redmi 10 ready for sale, simply removing contacts may not be enough, in which case it is advisable to perform a full factory reset, which will remove not only contacts, but also photos, applications, correspondence and system settings.

To perform the reset, go to Settings → About Phone → Reset. Select “Erase All Data.” The system will warn you that all files will be destroyed. Make sure you know the password for your Google and Mi Account account, as after the reset, the phone will require them to confirm ownership (anti-theft protection).

⚠️ Warning: Complete reset is irreversible. Make sure you copy all important files to your computer or the cloud, as it will be impossible to restore them after formatting your internal storage without professional hardware.

This method ensures that the new owner of the device does not have access to any of your records, and it also helps to correct software errors if the phone book is not working correctly, and once turned on, the device will look like you just took it out of the box.

Problems with deletion and duplicates

To recover, go to the web version of Google Contacts, click on the settings gear and select "Cancel Changes." Select a time interval (for example, "1 hour ago" or "yesterday"). The system will return all contacts that existed at that time.

⚠️ Attention: Cancel Changes affects the entire account. If you added new numbers today and restore yesterday's version, these new entries will be deleted.

For a Mi Cloud account, the procedure is similar: through i.mi.com, you can log into the contact cloud and recover deleted items from the cart if they have not been permanently deleted.
