Xiaomi Call Management: What is this program and how to configure it

Xiaomi smartphone owners, whether they are budget Redmi models or flagship lineups, often face mysterious notifications or entries in battery consumption, where a system process called “Maintenance of Xiaomi calls” appears. Many users are confused by the name, raising questions about the security and functionality of the component. In fact, it's not a third-party program that you downloaded from the Internet, but a deep system service integrated into the shell. MIUI or hyperos.

Its primary function is to make telephony work properly, including receiving incoming signals, identifying numbers, handling contacts, and filtering unwanted calls, and it's this component that connects the modem hardware to the user interface, allowing you to see a beautiful call card and use additional features like recording conversations, and understanding how this hidden program works will help you better control your smartphone.

In this article, we will discuss in detail why this service is needed, how it affects the autonomy of the device and what configuration options it hides in itself, you will learn whether to limit its background operation and how to properly configure spam protection so that your phone only rings when it is really necessary.

Systemic Essence: What Hides Under the Name

The process you see in Task Manager or in the application permission list is technically part of the standard set of Google services and add-ons from the manufacturer. It can be called differently in different versions of firmware, but its essence remains unchanged - this is the basic telephony module, which is responsible for processing the signals of the cellular network and converting them into user-friendly actions on the screen.

Often users confuse this service with the Dialer app, which is just an interface for dialing. However, Call Management runs deeper: it handles the logic of switching between SIM cards, activates speakerphone and controls the microphone during a conversation. Without this component, the smartphone would have become a useless piece of plastic, unable to maintain communication.

Importantly, it works closely with Mi Cloud services to synchronize call history and block spam numbers, and if you notice that this process consumes too much power, it may indicate a network signal problem or a software failure in the communication module.

Functional capabilities and hidden settings

While the standard call interface seems simple, Xiaomi Call Management provides advanced features that not everyone knows about, primarily a flexible call blocking system, where you can create blacklists not only by specific numbers, but also by masks, for example, by blocking all numbers that start with certain numbers, which effectively protects against telemarketers.

Another powerful feature is automatic conversation recording. Unlike many other smartphones that require third-party apps, this option is built in natively. You can set up automatic recording of all incoming and outgoing calls or select specific contacts. Files are saved in a secure folder that is only accessible through the recording menu.

⚠️ Note: Automatic recording of conversations may be limited by your country's laws. In some regions, when the recording is turned on, the interlocutor will hear a voice warning that the conversation is being recorded.

Also worth mentioning is the Antispam feature, which uses the Mi cloud database, which automatically detects numbers labeled by other users as spam, fraud or delivery, which allows you to screen out up to 90% of unwanted calls before the phone even rings.

Redirection and work with SIM-map

For dual-symbol smartphone owners, call management is becoming a critical tool, allowing you to flexibly adjust which SIM card to make a default call, as well as how to behave when a call arrives on the second line, and you can choose to wait, reject or switch mode, which is especially convenient in a business environment.

Battery consumption problems and optimization

One of the frequent complaints of users is the high battery consumption of the Call Management process, which is often associated with poor cellular signal: when the phone constantly searches for the network or switches between towers (2G/3G/4G), the communication module runs at its limit, consuming a lot of power.

In some cases, the cause may be a “stick” process after updating the firmware or crashing the Phone application. If you notice that the phone is warming in standby mode and discharges quickly, you should try to clear the service cache. To do this, go to Settings → Apps → All applications → Call management and select Clear cache.
