Have you ever noticed a strange service called Services Feedback on your Xiaomi app list that doesn't have an icon, doesn't show up on the menu, but regularly shows up on the active process list and consumes battery power. Many users wonder what kind of software it is, why it's installed without their knowledge, and can it be removed without risk to the system?
This article will reveal all the secrets of Services Feedback, from the official purpose (which Xiaomi prefers not to advertise) to the real impact on performance and privacy.We will analyze how the service collects data, what permissions it uses, and why its activity often coincides with a slowdown of the smartphone.
Spoiler: Services Feedback is not a virus, it's not a harmless system utility. It's directly linked to the loyalty program. MIUI and telemetry collection, and some data is sent even when the Internet is disconnected (through a cache).
What is Services Feedback on Xiaomi: official version vs reality
According to Xiaomi’s documentation, Services Feedback (sometimes referred to as com.miui.feedback) is a “feedback service” designed to:
- 📊 Collection of anonymous statistics on use MIUI (Application launch frequency, system errors).
- 🔄 Automatically send crash reports to Xiaomi to improve firmware.
- 🎁 Providing personalized offers (such as discounts on accessories) through the Mi Rewards program.
Independent tests (including analysis of traffic through Fiddler and Wireshark) show that Services Feedback:
- 📱 It tracks geolocation (even when switched off) GPS — cell-tower).
- 🔋 Records the battery level and the temperature of the processor in real time.
- 📡 Transmits data about connected Wi-Fi networks (including names and MAC-router addresses).
- 🛠️ Collects logs of all installed applications, not just system applications.
Moreover, the service is activated not only when there are obvious failures, but also when routine actions: for example, when connecting headphones, starting the camera or changing the brightness of the screen. POCO F3, who noticed spikes in com.miui.feedback activity in Settings → Battery → Using the battery at these moments.
How Services Feedback Affects Smartphone: Battery, Performance, Security
The main complaint users have about Services Feedback is the hidden consumption of resources.According to tests on Xiaomi 12T redmi K50, The service can consume up to 5-7% of battery power per day (with active use of a smartphone), and peak consumption occurs at night when the device is connected to Wi-Fi and charging – that’s when Xiaomi sends the accumulated data to its servers.
The second unpleasant thing is the slowdown of the system. Services Feedback uses background processes with a priority of foreground, which means that it can "take" resources from active applications. POCO X3 Pro complain of slowdowns when launching games (Genshin Impact, Call of Duty Mobile), which coincide with peak activity of the service.
Despite Xiaomi’s claims of “anonymity” of data, researchers from the University of Edinburgh (2022) have proven that:
⚠️ Note: Services Feedback transmits unique device identifiers (IMEI, Android ID, MAC-address, which can be used to link data to a specific user, this is contrary to the privacy policy MIUI, where it is claimed that the information is “depersonalized».
| Parameter | Impact of Services Feedback | How to check |
|---|---|---|
| Battery consumption | Up to 5–7% per day (peaks at night) | Settings → Battery → Battery use |
| Use of the CPU | Up to 15% load (when sending reports) | Annexes CPU Monitor or DevCheck |
| Data traffic | Up to 50–100 MB per month (background transmission) | → SIM-maps and mobile networks → Traffic usage |
| Confidentiality | Transfer IMEI, MAC-addresses, geolocations | Traffic analysis through Packet Capture |
💡
To see the real consumption of Services Feedback, restart your smartphone, open Settings → Battery and watch the com.miui.feedback process for 30 minutes. If it appears in the top, the service actively collects data.

- ⚠️ Problems with OTA-updates (in rare cases).
3. Through ADB: Team pm uninstall -k --user 0 com.miui.feedback will delete the service for the current user, but not for the system.
