Owners of Xiaomi, Redmi and POCO smartphones sometimes notice the mysterious name Smart Divert in the running process list or in the application menu. The appearance of an unfamiliar system component is often a concern, especially if it consumes resources or is constantly displayed in notifications. Users immediately wonder whether this is a hidden virus, an ad module or an important part of the MIUI operating system.
In fact, Smart Divert is a legitimate system service that manages the services of a telecom operator, and it is directly related to the functions of forwarding calls and messages, and unlike malware, this component is pre-installed by the manufacturer to properly operate the telephony. However, its behavior may change depending on your settings. SIM-maps and firmware versions.
In this article, we will take a closer look at the purpose of this process, analyze why it can load the battery, and find out whether it is safe to stop it, and understand the operation of Android background services will help you optimize the operation of the device without risking its stability.
Purpose and functions of the system service
The main task of the Smart Divert process is to synchronize the forwarding statuses between your device and the carrier servers. When you activate the Redirect, Voicemail or Redirect function. SMS», This service is the one that sends the appropriate USSD-requests or uses network protocols to configure the service.
It is worth noting that in modern versions of the HyperOS and MIUI shell, this component is often integrated into more general telephony services, but can be displayed as a separate process in the Task Manager, which is necessary to ensure continuous operation even when the main Phone application is closed.
Smart Divert is not limited to voice calls, it also monitors network status and when settings change (for example, switching from 4G to 2G or losing a signal) can initiate a recheck of redirect settings so that you do not miss an important call during an unstable connection.
- 📞 Automatic activation of forwarding to voice mail when line employment.
- 📱 Background synchronization of call settings with operator database.
- 🔔 Processing incoming USSD-notifications from support services.
- 🔄 Restore redirection settings after rebooting the device.
⚠️ Note: If you see that the Smart Divert process is constantly active and consumes a significant percentage of battery power, this may indicate a conflict of settings with the use of a smart divert. SIM-Map or network signal problems in your area.
It is important to understand that removing or forcing the service to stop unnecessarily could cause you to stop receiving missed call notifications when the phone is off or out of reach. Android relies on this component to comply with GSM standards.
Causes of high activity and battery consumption
One of the frequent complaints of users is the increased power consumption associated with the process of Smart Divert. This phenomenon is usually observed in situations where the smartphone constantly tries to contact the operator’s server to update the status of services, but receives an error or timeout.
The most common cause is an unstable cellular signal, and if you're in a border area, the communication module is constantly switching between the towers, and the Smart Divert tries to double-check whether the forwarding is active, which puts a strain on the processor and the radio module.
Another factor is the presence of two SIM-In devices that support Dual SIM The service must track the status of both cards simultaneously if one card is not properly registered on the network or requires the card to be registered. PIN-code, the process can enter a cycle of repeated attempts, which quickly puts the battery down.
Also worth mentioning are software failures after a firmware update: sometimes newer versions of MIUI contain errors in optimizing background processes, which prevents Smart Divert from falling asleep after completing a task, in which case cleaning the cache of the Phone application or resetting network settings helps.
- 📉 Constant search of the network in the area of poor coverage.
- 📡 Conflict of settings between the two SIM-map.
- 🐛 Error in the current version of the firmware MIUI/HyperOS.
- 🔒 Blocking background activity by an antivirus or optimizer.
To diagnose the problem, you can use the built-in battery analyzer. Go to Settings → Battery → Consumption and find the Smart Divert or Google Play Services list (often linked). If the consumption exceeds 5-7% per day without active calls, intervention is required.
Is it safe to remove or disable Smart Divert?
The issue of removing system components is always a pressing one. Since Smart Divert is part of the system telephony package, it cannot be completely deleted without root rights. Standard means the user can only forcefully stop the process or clear its data, but the system will automatically start it again whenever necessary.
Disconnection of service through ADB (Android Debug Bridge is theoretically possible, but it's not recommended for regular users. If you turn off this component, you risk losing the ability to configure forwarding through your phone's menu. USSD-codes that are uncomfortable.
Can I remove Smart Diverts through ADB?
Moreover, in some regions, the service is tied to VoLTE and Wi-Fi Calling, and its forced termination can deactivate these useful features, reducing the quality of communication in buildings with thick walls.
| Action. | Implications for the user | Recommended status |
|---|---|---|
| Clearing the cache | Safe, resets temporary errors | Permitted. |
| Forced stopping | Temporary shutdown, auto-start after 1-5 minutes | Safe. |
| Disconnection through ADB | Risk of communication loss, SIM failures, VoLTE problems | Not recommended |
| Removal (Root) | Complete disruption of the telephone module | Forbidden. |
If you want to save charge, it is better to identify the cause of the activity (for example, a bad signal) than to delete the system file. 99% of the time, the problem is solved by setting up the network or replacing it. SIM-newer-card.
Instructions for eliminating problems with the service
If you find that Smart Divert is eating a battery or causing a malfunction in the interface, perform a consistent diagnosis. Start with the simplest actions that do not require special skills.
The first step is to clean up the app data, which won't delete your contacts or your call history, but it will reset the redirect service itself, which often solves the problem of hanging.
☑️ Failure-resolving algorithm
Then check the redirect settings. In the Phone app, go to the call settings and make sure that there are no unnecessary redirect conditions to unknown numbers, sometimes viruses or user errors change these settings, making the service work idle.
If simple methods didn't work, try resetting the network settings. This will return all APN, Bluetooth and Wi-Fi settings to factory values, which will eliminate software conflicts. Path to function: Settings → Connection and Sharing → Reset Wi-Fi, mobile network and Bluetooth.
- 🔍 Check for system updates in the About Phone menu.
- 📲 Remove and re-insert. SIM-map, wiped contacts.
- 🛡️ Scan your phone with antivirus for malicious modules.
- 🌐 Try temporarily disabling the second. SIM-test-card.
⚠️ Note: Before resetting your network settings, make sure you remember passwords from your Wi-Fi networks as they will be deleted from your device’s memory.
Impact on the work of the two SIM-map
Owners of Xiaomi smartphones with two SIM-cards are more likely than others to encounter the activity of Smart Divert. The logic of the work here is complicated: the system needs to track the statuses for two different operators, each of which may have its own characteristics of implementing redirect protocols.
A common problem is the service race. SIM-The card loses the signal, Smart Divert can try to redirect calls to the second card or voice mail, but because of the priorities in the card. MIUI It causes a conflict, and it causes the phone to not ring at all or to call late.
💡
Advice: If you use two SIM-maps, configure for each separate function "Redirection in case of unavailability" through USSD-It's not just through the phone's menu, it's going to reduce the burden on the Smart Divert software service.
It’s also worth considering that some budget models may not handle the simultaneous operation of 4G on both cards, in which case the system puts one of the cards in 2G/3G mode, and Smart Divert begins to actively reconfigure the connection parameters, which is visually perceived as interface lags.
To minimize problems, it is recommended in the settings SIM-The cards explicitly indicate which card is used for mobile Internet and which is used only for calls, which will delineate data flows and reduce the frequency of redirect service requests.
Differences in different versions of MIUI and HyperOS
The behavior of the Smart Divert process varies significantly depending on the shell version. In older versions of MIUI 11-12, this process was often more “gluttonous” and less optimized. With the release of MIUI 13-14 and the new HyperOS, Xiaomi worked on optimizing background tasks.
In HyperOS, the call management mechanism has been rewritten, and now Smart Divert features are often hidden inside larger system packages, such as the MIUI Telephony Framework, to improve security and stability so that individual processes can’t affect the entire communication system.
Users of global firmware versions (Global) ROM) This process may be less common than Chinese users (CN ROM), where integration with local services requires more active background work, when installing Chinese firmware on a global device (or vice versa), conflicts may occur, since Smart Divert can search for service numbers that do not exist in your region.
- 🆕 HyperOS process is better integrated into the core of the system.
- 🌍 Global firmware has a less active background mode.
- 🇨🇳 Chinese versions require more resources for network services.
- 🔄 Security updates often patch telephony vulnerabilities.
If you are planning to flash your device, keep in mind that on custom firmware (LineageOS, Pixel Experience), the Smart Divert process may be missing or replaced by a standard AOSP Dialer, which often solves battery problems, but may deprive you of some of the branded Xiaomi call features.
💡
Smart Divert is a necessary system component for redirecting, not a virus, and its high activity is usually caused by problems with the signal or settings. SIM-maps, not malicious code.
