Owners of Xiaomi, Redmi and POCO smartphones, looking at the Memory Use or Battery section, often encounter a system process called Service and feedback. This component is built into the shell of MIUI and HyperOS, causing many questions from users who notice its activity even in the background. Many immediately begin to worry that the application is a virus or a hidden miner, but this is not true.
In fact, Service and feedback is a standard system module that collects technical information and interacts with the company's servers, and it is needed by developers to analyze the stability of the device and improve the quality of firmware, but despite its useful purpose, this service can consume a significant amount of battery power if it fails or if it constantly tries to send a report to the server when the connection is poor.
In this article, we will discuss in detail what data this process collects, why it can “eat” a battery and whether it should be forcibly stopped. Understanding the mechanisms of system services will help you to correctly customize the gadget for your needs without losing warranty or functionality.
The main purpose of the system process
The Service and feedback component (often displayed in the app list as Services and Feedback or Service and Feedback) is part of Xiaomi’s ecosystem, and its primary purpose is to automatically collect telemetry. When you encounter a bug in the system, an app crashes or the phone suddenly reboots, it is this module that forms a log file.
In addition to technical diagnostics, the service is responsible for operating the built-in loyalty program and review sections in system applications such as Security, Themes or Mi Browser, through which the company can conduct user surveys about the quality of the interface or offer users to evaluate new features. Background activity is necessary for data synchronization, but it does not need to be constant and aggressive.
It's important to understand that the process is not malicious. However, some firmware versions have seen the module continue to run unoptimized as it continues to hang in memory and consume resources even after successfully sending data or without a network, which often leads users to see it at the top of the energy consumption list.
⚠️ Warning: Don't confuse the Service and feedback system process with unknown applications you may have accidentally installed.If a package has a strange name or requires suspicious permissions not related to the system, it may be malware.
⚠️ Note: Forced shutdown of system services through ADB root rights without understanding the consequences can lead to unstable operation of the interface MIUI/HyperOS.
Impact on autonomy and productivity
One of the main reasons for the interest in this service is its impact on the autonomy of the device. In the normal state of operation, when the phone is connected to Wi-Fi and is on charge, the process is activated for a short time. However, users often complain that Service and feedback consumes up to 10-15% of battery power per day, a situation considered anomalous and indicates a software failure.
High energy consumption is usually associated with cyclical attempts to send an error report. If a smartphone is in the area of poor mobile network coverage or has an unstable Internet connection, the service can constantly try to establish a connection with the Xiaomi server, which keeps the radio module active, this leads not only to discharge, but also to heating the case.
Also worth noting is the impact on RAM: While the process itself is light, its constant activity prevents the system from fully falling asleep (go into deep energy saving mode), especially on devices with a small amount of RAM (3-4 GB), where each megabyte counts, in which cases the background service can indirectly affect the speed of switching between running applications.
What data is collected and transmitted by the service
The issue of privacy is a pressing one for many users. Service and feedback collects telemetry information, which includes device specifications, firmware version, list of installed applications and usage statistics. In the event of a crash, the report may include information about what action preceded the failure.
Xiaomi claims that the data is anonymized before being sent, but reports may include:
- 📱 Device model and sales region.
- 📶 Data on signal quality and networks used (Wi-Fi, 4G/5G).
- 📉 Processor and memory usage statistics at the time of error.
- 📸 Information on screen resolution and refresh rate.
Is it worth worrying about personal photos or correspondence? This process does not have direct access to the content of your messages or gallery unless you have sent a screenshot through the “Report an Error” feature. The main purpose of the collection is technical analytics, not surveillance of the user. However, for paranoid users, the ability to limit this data collection remains an important function.
Can I read the logs sent?
Instructions: how to disable data collection and feedback
If you are concerned about privacy or want to exclude any background battery consumption associated with this module, the functionality of MIUI and HyperOS allows you to limit its activity. Complete removal of the system component without superuser rights (Root) is impossible, but you can prevent it from collecting information and working in the background.
The first step is to disable the user experience improvement program, and you have to go to the system settings, find the privacy section and deaktivirujte the data, and that stops the generation of new reports, although the process itself can be started to check for updates.
The second step is to limit background activity, so you can prevent an application from running automatically or running in the background, and that's the most effective way to deal with battery discharge caused by that service.
☑️ Algorithm to disable data collection
For a deeper setup, you can use the developer menu or ADB-It's a very careful process, but it's a standard system tool that you can do the following:
- Open the Settings.
- Go to the Password and Security section (or Additional).
- Choose Privacy.
- Find the User Experience Improvement Program and disable it.
- Next, go to Settings -> About Phone -> MIUI version (click 7 times to activate the developer menu if hidden).
- In the developer menu, find debugging settings and error reports, making sure that automatic sending is disabled.
Permits and background management
The more subtle setup is done through the application management menu, where you can detail what is allowed and what is forbidden by a particular system process, which allows you to keep the service alive for critical system functions, but deprive it of the ability to spend resources without you knowing.
To access these settings, follow the following steps: Go to Settings → Applications → All Apps. In the upper right corner, click on three dots and select Show System Processes. Find Service and feedback in the list.
Inside the app menu, you’re interested in two main sections: Permissions and Battery. In the permissions section, you should disable geolocation, microphone, and contacts if they’re there (usually they’re not there, but it’s worth checking). In the Battery section, select No limits only if you need reports to be sent instantly, or Limit background activity to save charge.
| Setup parameter | Recommended value | Impact on the system |
|---|---|---|
| Auto-start | Off. | The service does not start itself after the reboot. |
| Background activities | Limited. | Reduces battery consumption, reports are sent less frequently |
| Network access | Wi-Fi and mobile | Allows you to send logs (can be completely disabled) |
| Notifications | Off. | Remove pop-up windows about errors |
💡
If you are using custom firmware or a global version with Google services cut out, disabling Service and feedback may be necessary for stable operation, as servers may not be available.
Should I remove Service and feedback completely?
Many advanced users are asking themselves if they want to debloat this component completely. ADB-commands or obtaining a Root-right. ADB looks like this:
pm uninstall -k --user 0 com.miui.misystemHowever, is the game worth the candle? Complete removal can lead to errors in the work of other system applications that are associated with this service, for example, automatic security updates may stop working or notifications from Xiaomi system applications may correctly display. In addition, when updating the firmware "over the air» (OTA) The removed component will return as it is part of the system image.
A safer alternative is to freeze the app via ADB, making it inactive without physically deleting files, which allows you to retrieve it at any time if you find problems with the functionality of the smartphone.
⚠️ Note: Before any interference with system processes ADB Make sure to back up your data completely. A team error can lead to a "bootloop).
💡
Deleting Service and feedback completely does not provide a critical performance boost, but it can disrupt system notifications.
Frequent problems and ways to solve them
Sometimes users are faced with a situation where the Service and feedback process is not just consuming the battery, but causes persistent pop-ups with errors or slows the interface, this can be due to conflicting versions of system components or damage to cache files.
The first thing to do in this case is to clear the application’s data and cache. Go to the app’s settings (as described above), select Storage, and click Clear and Clear cache, which will reset the error reporting queue that may have been stuck.
If the problem persists, check for system updates. Often Xiaomi releases patches that fix exactly such background service bugs. It is also worth checking the date and time on the device - time desynchronization can prevent a connection to the server and cause cyclic retries.
As a last resort, if the phone is on warranty and battery problems are critical, you can perform a full factory reset, which is guaranteed to remove any software conflicts caused by third-party software or changed settings.
