Do you launch your favorite app on Xiaomi and it suddenly shuts down? Or does the game dye 5 minutes after launch, POCO The reasons can be dozens - from the banal lack of RAM to deep firmware errors. MIUI.
In this article, we will not only list the possible culprits of failures, but also show you how to diagnose the problem specifically on your device. You will learn what Xiaomi settings most often lead to crashes, how to distinguish hardware from software failure, and why even top-end models like Xiaomi 14 Ultra are not immune to crashes.
1. Lack of RAM: Why MIUI kill off
One of the most common reasons for departures is aggressive memory management in the MIUI. The system actively closes the background processes to free up resources, but sometimes “oversteps the stick”, especially on budget models (Redmi Note 12, POCO M5) 4-6 GB of RAM.
How it manifests itself:
- 🎮 Games are dropped when switching to another application
- 📱 Messengers (Telegram, WhatsApp) lose unsent messages
- 🎵 Music players stop in 10-15 minutes in the background
Xiaomi has a hidden setting that adjusts the aggressiveness of memory cleaning to find it:
- Open the Settings. → The phone.
- Tap 5 times on the version MIUI, to activate the Developer Mode
- Back to Settings → Additionally. → For developers
- Find Process Limitation and select Standard Limitation or No Limitations
💡
If after changing the settings, the phone began to slow down, return the process limitation to the default value - this is a sign that your device really lacks RAM.
2. Container conflicts MIUI: Why even top-end apps are falling
MIUI It's known for its customization, but sometimes these changes break the compatibility with the applications. MIUI 14-15 had problems with:
- 🎬 TikTok (departures when scrolling the tape)
- 💬 Viber (No notifications are received)
- 🎮 Genshin Impact (Crashes when loading worlds)
Most often it's the fault:
- Redefined system libraries (e.g. modified WebView)
- Background restrictions for specific applications
- Energy saving profiles that block access to the network
How to check:
- Open Settings → Applications → Application Management
- Select a problem application → Permits
- Make sure it's on: 🔄 Auto-start 📶 Mobile data and Wi-Fi 🔔 Showing notifications
3.Storage problems: why apps crash when memory is scarce
On Xiaomi smartphones with eMMC memory (unlike the other two). UFS) Applications start to fly out when they're 80 to 85 percent full, and that's because of how the system manages the cache and the temporary files. 9A 32 GB of memory will start to slow down already with 25 GB of occupied space.
How to clean your memory correctly:
- 🧹 Remove the app cache in Settings → Warehouse → Cleanup
- 🗑️ Transfer photos to Google Photos or to a memory card
- 🔄 Use the built-in Deep Cleaning function (available in the MIUI 14+)
| Xiaomi model | Type of memory | Critical filling threshold | Recommendations |
|---|---|---|---|
| Redmi 9A/9C | eMMC 5.1 | 80% | Clean the cache weekly |
| POCO X3 Pro | UFS 2.2 | 90% | Putting heavy games on the map |
| Xiaomi 13 Pro | UFS 3.1 | 95% | Use cloud storage |
If the problem persists after cleaning, check the integrity of the file system:
adb shell df -hIf there are lines in the conclusion with 100% /data or /cache — This is a sign of serious errors requiring reset before factory settings.

4. Firmware errors: when to blame yourself MIUI
Sometimes, the apps are not your fault, but a firmware bug.
- 🐞 V MIUI 13.0.4 for Redmi Note 11 was a bug with the drop of Chrome when opening tabs
- 🎮 V MIUI 14.0.3. POCO F4 Unreal Engine games crashed because of drivers GPU
- 📱 V MIUI 15.1.2 Some apps didn’t start because of an Android Runtime bug
How to check if your firmware version is problematic:
- Go to Settings → About the phone → MIUI version
- Compare with the latest reviews on the forums (4PDA, XDA-Developers)
- If the bug is confirmed, wait for the update or roll back to the stable version.
For firmware rollback:
fastboot flash recovery recovery.img
fastboot reboot recoveryAttention:
Settings → System → Backup
Download the official firmware from the Xiaomi website|Check the battery charge (>50%)|Backup important data|Install the Mi Flash Tool drivers-->
5. Conflicts with Magisk and Root Rights
If you installed Magisk or other modifications to the system, it could break the application, especially those that are sensitive to root rights:
- 🏦 Banking applications (Sberbank, Tinkoff)
- 🎮 Anticheat games (PUBG Mobile, Call of Duty)
- 🔒 Annexes with DRM (Netflix, Disney+)
How to check the impact of Magisk:
- Open Magisk Manager and temporarily disable all modules
- Reboot the phone.
- Check if the apps continue to fly out
If the problem is gone, one of the modules is to blame.
- Include modules one at a time.
- After each turn on, test the problem app
- Once the flights return, you find the culprit.
💡
Even if you didn’t install Magisk yourself, some firmware from third-party developers (such as Xiaomi.eu) may contain conflict-provoking modifications preinstalled.
6.Overheating and trottling: why games fly out in 10-15 minutes
Many users POCO F3, Redmi K50 And other gaming smartphones are facing heavy-duty games (Genshin Impact, Honkai: Star Rail) due to trottling (forced performance decline) due to overheating.
How it works:
- 🌡️ The temperature of the processor reaches 80-85°C
- 📉 System reduces frequency CPU/GPU
- 💥 The game does not have time to process the graphics – crash
How to check:
- Install. CPU Monitor AIDA64
- Start the game and monitor the temperature.
- If the temperature is greater than 75°C. Measures are needed
Decisions:
- 🧊 Use a cooling cover or fan
- 🔧 Turn off background processes before the game
- 🔄 Lower the graphical settings in the game
- 🛠️ Replace thermopaste (relevant to older models)
💡
On some models (such as Black Shark 5), you can turn off trottling via the engineering menu. → Disable productivity restriction.
7.Problems with Google Play Services and Xiaomi Services
Departures can be associated with the work of background services:
- 🔄 Google Play Services – responsible for notifications, geolocation and authorization
- 📱 Mi Account – synchronizes Xiaomi data
- 🔒 Security App – scans applications for viruses
How to diagnose:
- Open Settings → Applications → All applications
- Find Google Play Services and Mi Account
- Check if there are any errors in the Warehouse section (e.g., Cache Error)
Decisions:
- 🔄 Update Google Play Services manually through Play Market
- 🗑️ Clear the cache and Mi Account data (Warning: this will unbundle you from your Xiaomi account!)
- 🔧 Turn off optimization. MIUI in battery settings for problem applications
💡
If Google Play Services has been cleaned, the notifications will stop working, restart your phone, and the services will automatically recover in 5-10 minutes.
8. Hardware problems: when iron is to blame
If none of the software methods helped, hardware malfunctions are possible:
- 🔋 Worn-out battery - when the voltage draws down below 3.5V processor is underpowered
- 💾 Damaged memory: Bad sectors on a chip eMMC/UFS
- 🔌 Oxidized contacts – for example, after moisture is ingested
How to check:
- Battery: Install AccuBattery and check battery health If the value is below 80% - it's time to change the battery
adb shell dumpsys meminfoLook for lines with native heap errors
⚠️ Warning: If the phone falls into a bootloop after the app crashes, it's a sign of a critical memory error. TWRP or Fastboot, as the device may fail completely.
Cost of repair:
