Owners of Xiaomi, Redmi and Poco smartphones often face a mysterious notification or process in task manager called “acceleration.” It is a system component of the MIUI shell or the new HyperOS that raises many questions for users who monitor the performance of the device. Many confuse it with third-party optimizer applications, but in fact it is an integrated mechanism for managing RAM.
The function is responsible for forcing background cleanups to free up resources for an active application. However, the aggressive policy of this module often leads to unpredictable behavior: notifications can come with a delay, and applications can restart every time they switch. Understanding the principles of this tool is critical for the proper configuration of the gadget.
In this article, we will examine the purpose of this process in detail, analyze its impact on autonomy and performance, and determine whether to interfere with its operation, you will learn how to properly manage background activity without using questionable third-party utilities, which often only harm the system.
What is the process of acceleration
The “acceleration” process (often displayed as com.miui.speedup or integrated into system services) is a native part of the Android operating system with an add-on from the manufacturer. Its main task is to monitor RAM consumption and force the completion of processes that the system considers inactive or redundant. Unlike standard memory management of pure Android, Xiaomi algorithms are set to more aggressively free resources.
It runs in the background and scans running apps all the time. If you rolled out a heavy game or video editor, that component might decide to kill their background process to keep the battery running or to speed up the current window, and it's a dual function: on the one hand, it helps older, smaller models run smoother, on the other, it breaks multitasking on powerful flagships.
⚠️ Note: Forced removal or freezing of this process through ADB root rights can lead to unstable operation of the interface, since many system services are tied to its cache cleaning logic.
It’s worth noting that in recent firmware versions, the functionality has been renamed or integrated into more general optimization services, but the essence has remained the same. Users often see pop-ups with memory cleaning animations that are triggered by this module when you click the “Clean” button in the menu of recent applications.
Impact on productivity and battery
The impact of background optimization on overall performance remains a debate among enthusiasts. On the one hand, freeing RAM theoretically should speed up the work of current tasks. MIUI aims to keep gigabytes of memory free, considering them reserved for system needs. On devices with 4 GB of RAM and less, this can really prevent strong lags when switching between heavy applications.
On the other hand, a constant start-up-forced-stop-re-run cycle consumes the CPU battery. When the system kills the background process of the messenger or navigator, the next time the device accesses it, the device spends more energy on a cold start than on keeping the process in sleep, creating a paradoxical situation where the accelerator actually reduces energy efficiency.
The impact is particularly noticeable on mid-range Snapdragon processor devices, where the task scheduler may conflict with Xiaomi’s algorithms. If you notice the phone warming up in a idle or discharges quickly at night, you may want to rethink the background settings that control the process.
How to Manage Optimization Settings
For those who want to take control of the situation, the system provides multiple levels of access to memory settings. The standard path is not always obvious, since Xiaomi hides these options in the depths of the menu. To access advanced management, you need to activate hidden developer functions or use special codes in the Security app.
The main management tool is in the Security app, which is pre-installed on all the brand devices, and this is where the user interacts with when cleaning up the memory, but to get a deep setup of each application, you have to go a long way through the system settings.
☑️ Adjusting background activity
There is also a method through the engineering menu, but it requires caution: the introduction of special commands allows you to change the thresholds of the memory cleanup, but this can lead to the fact that the system will begin to behave unpredictable, closing critical services.
Comparison with third-party accelerators
There are thousands of apps on the Google Play market with names like "Clean Master," "RAM Booster" and the like. People often wonder if they need another accelerator if they already have one built in? The answer lies in the architecture of modern versions of Android. Since Android 6.0, the system has learned to manage memory very effectively, making third-party process killers not only useless, but harmful.
Third-party applications often work on a stick-like basis, keeping their service running all the time, which monitors other processes, which puts additional strain on the processor and consumes battery. Xiaomi’s built-in acceleration program has deeper kernel rights and works at system priorities, making it more efficient but also more aggressive.
| Characteristics | System Acceleration (MIUI) | Third-party annexes |
|---|---|---|
| Level of access | System (Root rights are not required) | User-based (limited API) |
| Impact on the battery | Moderate (integrated into OS) | High (constant background service) |
| Cleaning efficiency | High (compulsory completion) | Low (often just hiding the process) |
| Security of data | Guaranteed by the manufacturer | The risk of telemetry collection |
Using third-party accelerators on Redmi and Poco smartphones often leads to conflicts where two programs attempt to complete the same process at the same time, causing cyclical interface reboots or lags.
Should I turn off memory optimization?
The decision to shut down or limit the system accelerator depends on the scenario of using your smartphone. If you use the device for simple tasks (social networks, calls, browser) and you have a model with 4-6 GB of RAM, aggressive optimization can even be useful, it will keep the system in good shape, not letting it “overgrow” garbage.
However, for users who are waiting for important notifications from working messengers, using smartwatches or activity trackers, standard settings can become a problem: messages can only come after opening the application, and step data can be synchronized with a delay, in which case important applications should be excluded from the control of the accelerator.
Hidden method of disabling MIUI optimization
Completely disabling the system memory cleanup mechanisms is not recommended, as this can overflow RAM and freeze the entire device.
Problems with notifications and their resolution
The most common complaint about the speeding program is the lack of notifications: users do not receive messages from Telegram, WhatsApp or email until they open the app, a classic symptom of the system’s “acceleration” process ending the messenger’s background service too quickly.
To solve this problem, it is not enough to simply allow notifications in the standard menu, go to the settings of a particular application, find the Battery or Energy Saving option and select the “No Limits” mode, and it is also recommended to fix the application in memory if this feature is available in the MIUI version, or simply not to swipe it from the list of recent tasks.
💡
If notifications are gone after a system update, try logging in again in the app and re-setting autorun permissions, as the update could reset exceptions to background work.
In some cases, enabling autorun for a problem application helps, which signals to the system that the process is important to the user and should not be completed by background optimization services.
Optimizing Memory Management Without Harm
Instead of fighting the system, you better learn how to manage it properly, and the key to stable operation is the presence of at least 15-20% of the device's free internal memory. If the drive is packed to the end, the acceleration mechanisms begin to work chaotically, trying to make room for temporary files, which causes brakes.
Regularly rebooting your smartphone (every 3-5 days) helps you reset accumulated memory management errors more effectively than any third-party program, and it is also worth checking the list of applications with the right to “Master over Other Windows” periodically, as they often conflict with the system accelerator.
The use of lightweight versions of social media applications also reduces the load on RAM, making the operation of “acceleration” algorithms less noticeable and more efficient for the user.
💡
System optimization on Xiaomi is a balance between performance and energy saving that can be customized to your needs, but you should not completely turn it off to avoid instability.
