Xiaomi’s current smartphones, which run MIUI or HyperOS, are famous for their functionality but often suffer from overconsumption of resources. Users often notice that the device starts to heat up and battery power melts in front of their eyes, even though no one uses the active screen, the fault is the background processes that continue to work even after you fold the application.
Android is inherently prone to storing as much data as possible to run quickly, but Xiaomi’s aggressive optimization sometimes backfires: Instead of saving energy, the phone uses it to support a dozen unnecessary services, and understanding how to manage these processes is key to keeping the gadget running smoothly.
In this article, we will not only look at standard limiting techniques, but also at the deeper settings available through the developer menu, and learn to distinguish systemically important processes from junk ones that can be safely stopped without risking system stability.
Causes of high activity in the background
The first step to optimizing is to understand what’s going on inside your smartphone, and background services can be caused by factors ranging from poor code optimization by app developers to the specifics of how the MIUI shell works.
Often users install apps that require permanent permissions to work in the background, such as activity trackers or weather widgets, but there are hidden processes associated with advertising modules or analytics that are built into the system by default.
⚠️ Note: Not all background processes can be safely turned off. System services responsible for communication, notifications and interface operation must remain active for the phone to function properly.
The analysis shows that social networks and messengers, which try to constantly update the feed or check for new messages, usually cause the greatest resource consumption, and limiting background activity for such applications can significantly reduce the load on the processor.
- 📱 Incorrectly working applications that create “cyclical” processes.
- ⚙️ Aggressive energy saving settings that paradoxically increase the load when trying to “freeze” the application.
- 📡 Background synchronization of cloud data and geolocation.
- 📢 Advertising IDs and Analytics Services within Free Software.
To figure out which application “eats” resources, the standard monitoring tool will help. Go to Settings → About Phone → All settings and click on the MIUI version several times to activate the developer menu if it is not already enabled.
Configuring the energy saving mode
The easiest and safest way to limit background processes is to use built-in optimization mechanisms. Xiaomi provides flexible power management tools that don’t require in-depth system knowledge.
The Security app has a Battery section where you can customize the behavior of each application you install, and it's important not just to choose a profile, but also to write down the rules for how to run in the background, and the smart constraint allows the system to decide when to close the application based on how often it's used.
For critical applications like instant messengers, you should set the status "No restrictions" to avoid missing messages, but for games and media services, you should apply strict restrictions, since they are likely not necessary in the background.
- 🔋 Open the Security app on the home screen.
- ⚡ Go to the Battery section and select Settings.
- 🛑 Click on Saving Charge in Apps.
- 📋 Select the desired application from the list and set the desired mode.
It’s worth noting that the “Full Limit” mode can cause the app to stop receiving notifications or updating content until the next manual launch, ideal for programs you rarely use.
⚠️ Warning: Installing the "Full Limit" mode on messengers (WhatsApp, Telegram) will delay incoming messages until the application is opened.
Use of the Developer Menu
For more advanced users who want to gain full control of the system, there is a hidden developer menu, and this is where the feature is located, allowing you to globally limit the number of processes running simultaneously.
To get into this menu, you need to go to Settings → About Phone and quickly click on the MIUI (or HyperOS) version 7 times. After the message “You became a developer” appears, a new item will appear in the settings menu.
☑️ Activation of the Developer Menu
In the For Developers section, you scroll down to "Background Process Limit" and the default is "Standard Limit," which allows the system to decide how many applications to store.
Changing this setting to “No More than 2 Processes” or “No More than 4 Processes” will force the system to force the closure of old applications when new ones are launched, which can significantly free up RAM, but will require more frequent reboot of heavy applications.
| Setting up | Description of the impact | Recommended value |
|---|---|---|
| Standard constraint | The system controls the memory itself. | By default. |
| No background processes | Applications are closed immediately after folding | Not recommended |
| No more than 2 processes | A strict restriction for weak devices | For old models. |
| No more than 4 processes | Balance between speed and multitasking | Optimally. |
The use of these settings is especially relevant for models with a small amount of RAM, such as the Xiaomi Redmi Note of previous years, and on flagship models with 8 GB of memory or more, such measures may be unnecessary.
Disabling Auto-Run Applications
One of the main reasons for the proliferation of background processes is the autostart function, and many apps prescribe themselves to autoboot to start immediately after you turn on your phone, even if you don't use them.
Autorun control in MIUI is in the same app, Security, and here's a complete list of programs that have permission to start with the system, and turning off the excess software is the most effective way to reduce the load on the processor in the first minutes after the device is turned on.
It is recommended to leave only system services and possibly instant messengers in auto-run if you are critical to instant notifications. All games, stores, banking applications and delivery services can be safely disabled.
- 🚀 Launch the Security app.
- 🔓 Select the permissions item in the lower menu.
- 📲 Click Auto Launch.
- ❌ Turn off sliders in front of unnecessary apps.
After making changes, the system may suggest restarting the device to apply the settings, which is normal, as some processes may have already started before the configuration change.
💡
After disabling the auto-run of banking applications, their first launch can take 2-3 seconds longer than usual, as the system will take time to initialize security services.
Specifics of MIUI and HyperOS
Xiaomi’s shells have a unique memory management architecture that is different from pure Android. MIUI algorithms often aggressively close out background apps, which can conflict with the settings of Android itself.
Newer versions of HyperOS have introduced an improved Memori system that intelligently expands virtual memory with permanent storage, but if background processes are not limited, it may work less efficiently by constantly accessing the disk.
⚠️ Note: On devices with HyperOS, it is not recommended to completely disable the system process of Google Play Services, as this will disrupt push notifications and geolocation.
If it's activated but the phone is slow, try turning it off and manually limiting background processes, and sometimes physical memory usage is more stable than virtual memory.
New firmware versions also include a "Memory Clean" feature in the notification curtain, and using this tool regularly in conjunction with the correct restrictions settings gives the best result.
Additional optimization methods
If standard methods have not worked, more radical measures can be taken, such as turning off animations and visual effects, which reduces the load on the GPU, indirectly affecting background performance.
The developer menu also has a "Background mode" item, which means that it doesn't include experimental features that can cause memory leaks, and resetting network settings can also help sometimes if background processes involve constant signal search or Wi-Fi failures.
ADB's Hidden Teams
Regularly cleaning the cache through the standard Cleanup menu also helps prevent the accumulation of temporary files that can provoke background activity.
The combination of competent management of auto-start, energy saving and process limits will give the best effect.
- 🧹 Regularly clean the cache of applications through the "Security" menu".
- 🔄 Remove unused apps so they don’t create background services.
- 📉 Turn off sync for accounts you don’t need all the time.
- 🌡️ Watch the temperature of the device, overheating often provokes trolling and lags.
Compliance with these simple rules will significantly extend the life of the battery
