Why Xiaomi Redmi is slowing down and how it relates to background processes
Xiaomi Redmi smartphones based on MIUI often face the problem of slowing down due to excessive background processes. Even new models like the Redmi Note 13 Pro+ or Redmi K70 can slow down if the system is not optimized, the reason lies in the MIUI architecture, which aggressively caches applications and runs services for user convenience - but often this leads to overload of RAM and increased battery consumption.
Background processes fall into three categories: system (critical for Android and MIUI), service (responsible for synchronization, notifications, geolocation) and applications (autostart messengers, social networks, games). Disabling them at random is dangerous - you can disrupt the stability of the system. However, competent optimization allows you to increase battery life by 15-25% and speed up multitasking, especially on budget models like Redmi 12C or Redmi A2+ with 4-6 GB of RAM.
In this article, we will discuss which processes can be safely turned off and which should not be touched, even if they seem “extra” and also consider the hidden settings of MIUI, which the manufacturer does not advertise, but which actually affect performance.
MIUI System Processes: What You Can and Can't Touch
System processes in MIUI often scare users with names like com.miui.daemon or com.xiaomi.finddevice, some critical, others only conditionally useful.
| Title of the process | Responsible for... | Can I turn it off? | Effects of disconnection |
|---|---|---|---|
| com.miui.analytics | Collection of anonymous usage statistics | ✅ Yes. | Xiaomi will no longer send data (without affecting the work) |
| com.xiaomi.market | Work of the corporate app store GetApps | ✅ Yes. | Notifications for “recommended” applications will disappear |
| com.miui.systemAdSolution | System advertising in MIUI (banners in settings) | ✅ Yes. | Disappear advertising in the menu settings and standard applications |
| com.miui.daemon | Managing hardware components (Wi-Fi, Bluetooth, NFC) | ❌ No. | Failure of communication modules, inability to enable wireless interfaces |
| com.xiaomi.finddevice | Find My Device (Similar to Find My Device) | ⚠️ Conditionally. | You can’t track your phone when you lose it, but it saves up to 5% of your charge. |
Special attention should be paid to the process of com.miui.personalassistant, which is responsible for the smart assistant MIUI (voice commands, contextual prompts), its shutdown will free up to 200 MB of RAM, but will deprive you of the ability to use voice search on the system. If you do not use it, safely deactivate.
⚠️ Attention: Disabling Processes through Settings → Annexes → Application management → All applications don't always work well, some services restart after they're restarted, and you'll need permissions to shut down completely. ADB root.
How to disable auto-start applications: step-by-step instructions
Auto-run is the main reason why background processes eat up resources. In MIUI 14/15, the setting is hidden deep in the menu, and many users don't even know it exists. Here's how to find it:
- Open Settings → Applications → Application Management.
- Slip on the three dots in the upper right corner and select AutoRun.
- You'll see a list of all the apps that you can turn off autoboot: 📱 Messengers (Telegram, Viber, WhatsApp) – if you do not need instant notifications. 🎮 Games (Genshin Impact, PUBG Mobile, Honkai: Star Rail – They often hang in the background even after closing. 🛒 Marketplaces (AliExpress, Wildberries, Ozon) – constantly synchronize data. 📺 Social networks (TikTok, Instagram, Facebook) – the main “eaters” of the battery.
Once you turn off auto-run, apps won't start automatically when you turn on your phone or connect to the Internet, but they can still run in the background if you open them manually, and you'll need to limit background activity to fully control them.

Background activity restriction: Hidden MIUI settings
MIUI has a hidden feature called Background Activity Limitation, which allows applications to block access to resources when they are folded, a feature that is more stringent than simply turning off autostart, and requires caution.
To activate it:
- Go to Settings → Battery and Performance → Battery Management.
- Select the App Selection and find the one you want (like Facebook or AliExpress).
- Slip on Background Activity Limitation and select Limit.
If you accidentally turn off a critical process, the symptoms will appear immediately: freezes, reboots, no network or a black screen, in which case only resetting the settings or manually turning the service back on through ADB will help.
💡
Before disabling any process, check its name on Google or forums (such as 4PDA). Often users share experiences of what services can be safely turned off on a particular Redmi model.
How to check which processes are loading the system
Before you turn something off, you need to understand what the brakes are to blame for, and MIUI has built-in tools and third-party utilities to do that.
Method 1: Built-in activity monitor
- Open Settings → About Phone → MIUI version and tap 7 times on the line with the version to activate Developer Mode.
- Go back to Settings → Additional → For developers and find the Activity Monitor.
- Here you will see a list of processes sorted by CPU load, memory and battery.
Method 2: Third-party applications
- 📊 CPU Monitor – shows the processor boot in real time.
- 🔋 AccuBattery – analyzes battery consumption by application.
- 🧹 Greenify – helps to “sleep” unnecessary background processes (requires root for full functionality).
If you see an app hanging around the top of your resource consumption (like Facebook or Mi Video), it should be either restricted or removed, especially for low-RAM models like the Redmi 9A (2GB) or Redmi 10A (3GB).
