You run Instagram, Telegram or a game on Xiaomi, and then the app suddenly shuts down after a few seconds? This problem is familiar to many owners of Redmi, Poco and Mi smartphones, from budget models to flagships. 80% of the time it is not the "glitch" of the programs themselves that is to blame, but the features of the MIUI firmware or hardware limitations of the device.
In this article, weโll break down 10 real reasons why apps are coming to Xiaomi, from the banal lack of RAM to the hidden power saving settings that aggressively close the background processes. Youโll get step-by-step instructions for diagnosing and solving the problem, including rare tips for devices with MIUI 14/15 and HyperOS. And at the end, a checklist for a quick test of your phone.
1: Aggressive Optimization of MIUI: Why the System Kills Applications
The main reason for the sudden closure of applications on Xiaomi is the built-in โBattery Optimizationโ feature, which is too zealous to save power. Unlike โpureโ Android, MIUI (and the new HyperOS) uses its own process control algorithms, which often mistakenly regard active applications as โbackgroundโ and force them to close.
Particularly affected are:
- ๐ฑ Messengers (WhatsApp, Viber, Telegram) โ notifications stop coming, chats are not updated.
- ๐ฎ Games (Genshin Impact, PUBG Mobile) โ are dropped off on download or during gameplay.
- ๐ Social networks (TikTok, Instagram) โ are closed when you scroll through the feed.
- ๐ Navigators (Yandex.Maps, Google Maps) - lose connection during the route.
How to check if optimization is to blame:
- Open Settings โ Applications โ Application Management.
- Select a problem app (such as Telegram).
- Slip on Battery Limits.
- If the mode is limited or optimized, the system nails it.
โ ๏ธ Warning: Xiaomi has a hidden Deep Optimization mode with MIUI 14+, which cannot be disabled through standard settings. It activates automatically when the battery is low (less than 15%).
Lack of RAM: how to check and what to do
Xiaomi is known for saving on RAM even in the mid-range segment. For example, the Redmi Note 12 in the basic version has only 4 GB of RAM, of which the system eats up to 2 GB for its needs, leaving critically few resources for applications.
How to know if there is enough memory:
- Open Settings โ About the phone โ Memory status.
- See the โUse of RAMโ graph in real time.
- If you have less than 500 MB of free work, this is a critical threshold for stable operation.
| Xiaomi model | The volume of RAM | Minimum free RAM for stable operation | The risk of departures |
|---|---|---|---|
| Redmi 9A/10A | 2-3 GB | 300-400 MB | โ Very tall. |
| Redmi Note 11/12 | 4-6 GB | 500-700 MB | โ ๏ธ Medium. |
| Poco F4/F5 | 6-8 GB | 800โ1000 MB | โ Low. |
| Xiaomi 13/14 | 8-12 GB | 1.5โ2 GB | โ Minimum |
Solutions for RAM shortage:
- ๐งน Background Cleanup: Enable Settings โ Special Features โ Background Cleanup (remove unused processes).
- ๐ Memory Extension: Up to 3 GB of virtual RAM can be added to MIUI 13+ with built-in memory (path: Settings โ Additional โ Memory Extension).
- ๐ซ Disables animations: Reduces system load. Activates via Settings โ About Phone โ Version MIUI (tap 5 times to unlock Developer Settings, then find Windows Animation = 0.5x).
๐ก
If you have Xiaomi with 4GB of RAM, never open more than 3 heavy apps at a time (e.g. game + navigator + messenger).
3: Conflicts with the MIUI/HyperOS shell: hidden settings
MIUI and the new HyperOS have unique application management mechanisms that often cause crashes.
- ๐ Super Power Saving โ blocks background activity of all applications except system applications.
- ๐ก๏ธ Privacy Protection: Restricts access to sensors and networks for suspicious programs.
- ๐ Autocleaning โ forcibly closes applications when the screen is locked.
How to disable problem functions:
- Super energy saving: Settings โ Battery โ Battery mode โ Select โPerformanceโ.
- Privacy Protection: Settings โ Privacy โ Special Permits โ Auto Run (enable for the right applications).
- Auto Clean: Settings โ Applications โ Auto Clean โ Disable.
A critical feature of HyperOS: in the new shell, Xiaomi added a โdynamic resource allocationโ that automatically limits background processes if the CPU temperature exceeds 45ยฐC. This leads to departures even without visible load.

4. Problems with cache and application data
A damaged cache or application data is the second most common cause of departures.
- โก Incorrect update (e.g. WhatsApp has been updated but old data conflicts with the new version).
- ๐๏ธ Cache overflows (more than 500 MB for a single application).
- ๐ Failure to install (e.g., downloaded APK from a third-party source).
How to clean the cache and data:
- Go to Settings โ Applications โ Application Management.
- Select a problem app (like Instagram).
- Slip the vault. โ Clear the cache.
- If it doesnโt work, click Clear Data (โ ๏ธ this will delete all settings and inputs!).
โ ๏ธ Warning: Xiaomi has a bug with MIUI 14+: after clearing the data, some apps (like the Google Play Store) may not start until you restart the phone.
โ๏ธ Checklist before data clearing
5.Outdated firmware or beta version of MIUI
Xiaomi regularly releases updates for MIUI and HyperOS, but not all of them are stable. Statistically, 30% of app crashes are due to bugs in specific versions of firmware.
- ๐ฑ MIUI 13.0.4โ13.0.6 โ Massive Google Play Services outages.
- ๐ฅ MIUI 14.0.2: Conflicts with the Unreal Engine (games that are relegated to the Unreal Engine)
- โก HyperOS 1.0.3โ1.0.5 โ multitasking problems on 6GB of RAM devices.
How to check and update the firmware:
- Open Settings โ About the phone โ System update.
- If a new version is available, install it.
- If there are no updates, but the problem remains, try to roll back to the stable version via Fastboot.
List of stable versions for popular models:
| Model | Recommended version of MIUI/HyperOS | Famous bugs |
|---|---|---|
| Redmi Note 11 | MIUI 14.0.4.0 | Camera flights to Snapchat |
| Poco F3 | HyperOS 1.0.6.0 | Lags in Genshin Impact with high settings |
| Xiaomi 12T | MIUI 13.2.5.0 | Google Pay is not working after the update |
๐ก
If you start crashing after the firmware update, try resetting your network settings (Settings โ SIM- of maps and networks โ Network resetting). In 40% of cases, this solves the problem without rolling back.
6. Viruses and Malware: How to Check Your Phone
Malware often disguises itself as system processes and interferes with applications, as is the case at Xiaomi:
- ๐ฆ Applications are closed immediately after launch.
- ๐ฅ The phone is warming up without loading.
- ๐ The battery is run down in 2-3 hours.
- ๐ซ There are pop-ups with ads.
How to find and remove viruses:
- Install Malwarebytes or Dr.Web Light from the Play Store.
- Run a deep scan.
- Note the applications with Administrator or Accessibility rights (path: Settings โ Applications โ Special Access).
- Remove suspicious programs and restart your phone.
โ ๏ธ Warning: On Xiaomi with the bootloader unlocked, viruses can hide in system folders (/system/priv-app), in which case only a full factory reset will help.
7 Hardware problems: overheating, battery wear, damaged memory
If the programs are crashed even after resetting, the problem may be in the hardware:
- ๐ฅ CPU overheating โ at temperatures above 50ยฐC, Xiaomi is forced to reduce performance, leading to crashes.
- ๐ Worn-out battery โ if capacity has dropped below 70%, the phone may suddenly shut down, simulating the crash of apps.
- ๐พ Damaged flash memory โ Broken sectors cause malfunctions when reading these applications.
How to diagnose hardware problems:
- Overheating: Install AIDA64 and check the temperature of the processor under load. Normal: up to 45ยฐC in plain, up to 65ยฐC in games.
- Battery: Enter ##4636##, select Battery Information. If Wear Level > 30%, a replacement is required.
- Memory: Run the test in SD Maid or DiskDigger. If you have broken sectors, contact the service.
Important: on Xiaomi with Snapdragon 8 Gen 1/2 processors (like Xiaomi 12/13 Pro), overheating is a known problem due to a weak cooling system.Solution: use a gaming cooler or limit FPS to games up to 60 frames.
8 Conflicts with Magisk, root rights and custom firmware
If you installed a Magisk, TWRP, or custom core (like KernelSU), it could disrupt the stability of the system.
- ๐ ๏ธ Apps fly out when you request root rights.
- ๐ Google Play Services are constantly restarted.
- ๐ซ Banking applications (SberBank, Tinkoff) are not working.
How to fix it:
- Open Magisk Manager and check the module list. Turn off suspicious modules.
- If the problem has occurred after the Magisk update, roll back to version 25.2 (stable).
- For banking applications, install the Universal SafetyNet Fix module.
- If nothing helps, do full unroot in Magisk and re-flash stock recovery.
โ ๏ธ Warning: On Xiaomi with HyperOS, root rights break down MIUI Optimization, which leads to system application crashes. Solution: Once you get the root, disable optimization via ADB (the team in the spoiler above).
