Xiaomi’s modern smartphones have huge memory and powerful processors, but even they can start to work slower if the internal database is full of excess information. One of the common reasons for the slowdown of the interface and problems with synchronization is a bloated phone book containing thousands of records, including old numbers, duplicates and remote contacts. Clearing the list is not just a matter of aesthetics, but also a necessity for stable operation of the device.
Owners of gadgets often face a situation when after changing the operator or transferring data from the old device, digital garbage accumulates in memory. Deleting unnecessary records manually can take hours if you do not know about the hidden functions of the MIUI or HyperOS system. In this article, we will discuss all the current cleaning methods, from standard methods to the use of specialized utilities.
Do not ignore the need to periodically review your data, as it directly affects the speed of finding the right subscriber and the correctness of the messengers. We will consider how to safely get rid of excess without losing important numbers of friends and colleagues. Competent contact management is a basic skill of every Android user.
Preparation for cleaning and backup
Before we start mass deletion, it's critical to protect ourselves from the accidental loss of valuable data. Misdirecting the number instead of spam is a common problem that takes a long time to solve, so the first step should always be to back up.
The most reliable way to keep contacts in the Xiaomi ecosystem is to use a cloud service MI Cloud or Google account, which allows you not only to snapshot the current phone book, but also easily restore it on any other device, the synchronization process takes only a few minutes with a stable Internet connection.
💡
Before starting a large-scale cleaning, be sure to turn on the display of hidden numbers in the contact settings so as not to accidentally delete important service records.
You should also pay attention to where your numbers are stored: SIM-It's in your phone's memory, or in the cloud, and it's the choice of removal method. SIM-card, make sure you have access to its management through standard system means.
⚠️ Attention: Removed from SIM-It is almost impossible to restore contacts without specialized equipment, so transfer them first to the device memory or cloud.
Removal of contacts with standard MIUI and HyperOS tools
The built-in Contacts app in the MIUI shell and the new HyperOS provides a powerful enough toolkit to work with a phone book. The basic method of deleting one or more records is intuitive even for beginners, and you just need to open the desired number and select the appropriate option in the menu.
However, if your goal is to delete a group of contacts at once or clear the entire list, the algorithm of actions will be different: you will need to use multiple choice mode, which allows you to mark dozens of records at once and delete them with a single touch, which saves time.
☑️ Group removal algorithm
The interface may vary slightly depending on the firmware version, but the logic remains the same for all Xiaomi, Redmi and POCO models.
💡
Group contact allocation works only in list viewing mode, but not in search or favorite mode.
Cleaning duplicates and combining records
One of the most annoying problems is the emergence of duplicates: the same person can be recorded twice or three times with or without different numbers.The Android system often offers to automatically combine such records, but sometimes this process requires manual user intervention.
To solve this problem, the standard app has a feature called Clear Duplicates, which scans the database, finds matches by name or phone number, and suggests combining them into a single card, which helps to eliminate visual noise and makes it easier to search.
If the automatic search didn't work, you can use manually combining, select the main contact, click the edit menu, and find the option "Merge with another", and the system will offer a list of similar entries from which you can choose the one you want to merge.
- 📱 Open the contact with the duplicate and click "Edit».
- 🔗 Select the item “Connect” or “Connect Contacts».
- ✅ Confirm the choice of a second contact for data merger.
- 💾 Save Changes to Update the Database.
Once all the data (photos, numbers, emails) are combined, they are stored in one card, and the extra duplicates disappear, especially for those who have changed SIM cards or synced with different accounts.
Managing Contacts through Google Contacts
The most effective tool for deep cleaning the phone book is the Google Contacts web interface, which allows you to work with data on the big screen of your computer, which is much more convenient than pointing your finger at the display of your smartphone. All changes are instantly synchronized with your Xiaomi.
To get started, go to Google’s contact site and log in to the same account you use on your phone, and it offers advanced functionality including mass deletion, group filtering, and recovery over the past 30 days.
The Cancel Change feature, which allows you to roll back the state of the phone book in time, is particularly noteworthy, and it saves you in situations where you accidentally deleted the wrong thing or when a viral mailing list with fake numbers has been entered into the database.
| Function | Where to find out. | What do you need? |
|---|---|---|
| Delete | Checkbox on the left on behalf | Complete deletion of the record |
| Unite | Menu "Combine and Fix" | Merger of duplicates |
| Restore | Cancel Changes menu | Recourse to 30 days |
| Exports | Export menu | Save to CSV/vCard |
Using a web interface also makes it easy to rename contact groups, such as “Work”, “Family” and “Service”, which makes navigation easier and allows you to quickly hide or show certain categories in your phone.
Working with contacts on SIM-map
Many users still keep numbers on the SIM-But the SIM memory is limited, and the functionality of working with such contacts in Android is reduced. Deleting records directly from the SIM card is possible, but it requires care.
To remove a contact from the SIM, go to the Contacts settings, select Import/Export or Contact Management. SIM-The system will prompt you to select numbers to delete or clean everything at once.
⚠️ Note: When removing contacts from SIM-They disappear irrevocably, as they do not fall into the basket of the Android system.
Experts recommend not storing the main database of numbers on the SIM card, using it only as temporary storage when changing the phone, and then transfer all data to the cloud profile of Google or Mi Account, which will ensure the safety of the data even if the SIM is physically lost.
Why can SIM contacts be displayed incorrectly?
Use of third-party cleaning applications
If you can't remove thousands of records with standard tools, specialized software comes to the rescue, and there are a lot of tools available in the GetApps or Google Play store, like Duplicate Contacts, Clearer, and other tools, that can find hidden duplicates and delete empty records.
When installing such applications, MIUI will request extensive permissions to access your data, which is necessary for the program to work, but requires trust in the developer. Always check ratings and reviews before installing software that works with personal information.
One effective method is to use file managers with database editing, but this requires root rights and a deep knowledge of the Android structure.
- 🧹 Duplicate Contacts – specializes in finding full copies.
- 📂 Contacts Optimizer – allows you to filter contacts without names or numbers.
- 🛡️ CCleaner – has a module for cleaning garbage in the phone book.
After the third-party application is working, it is recommended to restart the smartphone so that the system re-indexes changes in the database, which will help to avoid display errors and interface freezes.
Solving and restoring data
Sometimes, once deleted, contacts may be resurrected or not completely disappear, and this is due to synchronization. If you delete a number on your phone but it's still in the Google cloud, the next time you connect to the Internet, it will be rebooted to your device. To avoid this, delete the contacts from all synchronized sources.
If you accidentally delete an important contact, don’t panic. Within 30 days, it can be restored via the Google Contacts web interface (Basket or Cancel Changes section). For Mi Cloud, there is also a similar feature in the web version of the cloud.
💡
Synchronization works both ways: Deleting in the cloud will remove contact on the phone, and vice versa.
In case of software failures, when the phone book stops showing correctly, clear the cache of the Contacts and Phone app through the system settings.This will not delete your data, but will reset temporary files that may have caused the error.
