The situation where your favorite mobile app or resource-intensive game suddenly closes on a Xiaomi Redmi smartphone is familiar to many users.The screen just flashes and you find yourself back on the desktop, losing all progress. This happens on both budget models and flagship devices in the Redmi Note or Poco series, which is often puzzling.
The main reason lies in the aggressive management of resources of the Android operating system in conjunction with the shell of MIUI or the new HyperOS. The system tries to save battery power and prevent overheating by forcibly completing processes that consume too much power or RAM. Understanding the mechanisms of the background processes is the first step to solving the problem.
In this article, we will discuss in detail the technical aspects that affect the stability of gaming applications, you will learn how to properly configure the system so that it does not perceive your game as a malicious or difficult process that requires immediate stop.
Lack of RAM and overflow of cache
The most common, but common, reason for crashes is the banal lack of free RAM (RAM), which, when you run a heavy game, requires a certain amount of resources to download textures and scripts. If there are many other applications running in the background, the system simply does not have enough space to host game data, and it forcibly closes the game.
This is especially true for models with 4GB or 6GB of RAM, and the MIUI shell is known for its gluttonous consumption of system resources, and even if you close all windows, some services remain active, taking up precious megabytes.
⚠️ Attention: Constant lack of memory leads not only to departures, but also to accelerated wear of the drive due to the active operation of virtual memory.
You can use built-in tools or third-party utilities to diagnose your current memory state, but a standard cleaner often only masks the problem, temporarily freeing up space that system services immediately occupy.
The solution can be manually cleaned or prioritized. You need to make sure the game is top priority. Go to Settings → About Phone and click on the MIUI version several times to activate advanced features if they are hidden by the manufacturer.
Also worth paying attention to is crowded cache. Accumulated temporary files can conflict with new game updates. Regularly clearing the cache through Security → Cleaning helps keep the system on top.
Aggressive battery optimization in MIUI and HyperOS
Xiaomi’s proprietary shell is famous for its tight energy savings. System algorithms constantly monitor the energy consumption of each application. If the game goes beyond the established limits or runs in the background (for example, to download assets), the system manager can kill the process without warning.
This often happens when you turn down a game to respond to a message, and when you come back, you find that the application has restarted, and the system thinks you're not using it anymore, and it turns off the CPU power for that application to save power.
To prevent this, you need to manually configure the power saving settings for a particular application. Go to Settings → Apps → All apps, find your game and select Saving Charge.
In the menu that opens, select the No Limits option, which will make it clear to the system that the application is critical and you don't have to stop it, and without that step, even a powerful processor won't save you from program crashes.
💡
Use Performance mode in the Security → Battery app only while playing, as it significantly speeds up the discharge of the device.
Problems with overheating and processor trotting
Heat generation is a natural process when mobile processors are under load, but when the temperature reaches critical levels, a protective mechanism called trotting comes into play, the processor artificially lowers its frequencies to cool down.
If the frequency drops sharply or the temperature rises too quickly, the game may simply stop responding or crash to the desktop.This is a protective reaction to prevent physical damage to components of the Redmi smartphone.
Often overheating is caused not only by the game itself, but also by external factors: the use of a thick protective case, playing in direct sunlight or simultaneously charging the device during gaming significantly worsens the heat sink.
| Symptoms. | Probable cause | Decision |
|---|---|---|
| Screen dims, FPS falls | Beginning of trotting | Reduce the schedule in the game |
| A sharp departure without errors | Critical overheating | Let the device cool down |
| Departure after 30 minutes of play | Heating of the case and battery | Take off the cover, play at the fan. |
| Departure on charging | Overheating from charger | Do not play while charging |
You can use a built-in game mode plugin or third-party apps like the Throttling Test CPU to monitor temperatures, and make sure the temperature does not exceed 45-50 degrees Celsius in peak loads.
Why can't you play in the cold?
Conflicts of Android versions and GPU drivers
Sometimes the problem is deeper, in software incompatibility: Games are constantly updated, requiring new versions of Google Play Services libraries or graphics accelerator drivers. If your Xiaomi Redmi is running an old version of Android or has not updated system components in a long time, conflicts are inevitable.
This is especially common after major shell updates, when game developers have not yet optimized their products for new APIs, and errors related to graphics rendering appear in the system logs at this point.
It is important to keep an eye on the updates to Google Play Games and WebView, which are responsible for the correct display of interfaces and the operation of game accounts, and their obsolescence is a frequent cause of instability.
Check for updates from the Play Market Store. Go to your profile and select App and Device Management. If there are updates available for system components, install them immediately.
It is also worth checking the integrity of the game's files. In the game's launcher settings (such as PUBG or Genshin Impact), there is often a "Recover" or "Check Files" function, which will take time, but will eliminate errors of corrupted data.
Setting up the Game Turbo game mode
Xiaomi smartphones have a built-in Game Turbo (formerly Game Center) tool that is designed to optimize performance. However, misconfiguring it or ignoring it completely can lead to problems. It manages the allocation of CPU and GPU resources.
If the game is not added to the Game Turbo list, it will run as normal, receiving less priority. If the settings inside the Game Turbo are incorrect (for example, aggressive saving is included), this will also cause crashes.
☑️ Setting up the Game Turbo
Go to the Safety → Game Turbo app. Make sure your game is on the list. Click on the gear icon or settings for a particular app. Here you can set maximum performance and turn off incoming calls, which can also interrupt the process.
Some versions of MIUI have hidden Game Turbo settings available through an engineering menu or special codes, but standard settings are usually enough to stabilize the work.Don't forget that the Game Turbo can also clear the memory before launching a game.
⚠️ Warning: Game Turbo's "boost" features can raise the temperature of the device. Use them with caution on older Redmi models.
Damage to the game files and Google Play cache
Even if all the system settings are perfect, crashes can cause broken files, such as an interrupted download, a file system crash, or an update error, and the Google Play store cache can also store incorrect license or application version data.
Symptoms of file corruption often manifest as crashes at the stage of downloading the developer logo or at a certain point in gameplay.
Go to Settings → Apps → All Apps → Google Play Store. Select Storage and click Clear Cache and Clear Everything. Fear not, it won't delete your installed games, but it will reset the store settings.
If this doesn’t work, you’ll need to reinstall the problem game completely, and it’s important to remove not only the shortcut, but all the residual files, so after you uninstall the application, use the file manager and check the folders at the root of the internal memory with the game or developer name.
💡
Complete reinstallation of the game with pre-cleaning of residual files solves the problem of departures in 80% of cases, if it is not the hardware.
Third-party modifications and cheats
Using modified versions of games, cheats, scripts or third-party launchers is a sure way to unstable work. Anti-chit systems of modern online games (such as Brawl Stars, Call of Duty Mobile) actively scan the memory of the device.
If you find any outside interference or modified system files, the game can be forced to close, not a bug, but a security mechanism. Even if you don't use cheats, having root rights or an unlocked bootloader can be considered a threat by the security system.
If you have installed any mods, graphics plugins or "accelerators," delete them. check the list of installed apps for suspicious programs that you don't remember.
It’s also worth checking if USB debugging is enabled (USB debugging is on the developer menu).Some games block startup or run unstable if this mode is active, as it allows external programs to interfere with the process.
Hardware limitations and storage wear
Redmi smartphones, especially in the budget segment, use eMMC or cheap versions of UFS. Over time, their write and read speeds decrease, which leads to errors when loading data in the game.
If the memory is more than 90% occupied, the speed of its operation drops significantly, the system has no place to place temporary files, and the application crashes. Always leave at least 5-10 GB free for normal operation of the system.
In addition, battery degradation can cause voltage drawdowns under load, the processor does not have enough current to operate at high frequencies, and the process crashes. 3-4 For years, that's a very likely reason.
- 📉 Check the memory fullness in Settings → The phone. → Warehouse.
- 🔋 Evaluate the status of the battery through security → Battery (status indicator).
- 🌡️ Watch for heating in the lower part of the case, where the processor is located.
In the event of critical wear and tear on the drive or battery, software techniques may not help, in which case it is worth considering resetting to factory settings or replacing hardware components in the service center.
