Many users of Xiaomi, Redmi and POCO smartphones notice that even after a full reboot of the device, some programs are again active, a phenomenon called autorun, and it raises a lot of questions for those who want to squeeze the most out of their battery and RAM. In Android environments, especially with the shell of MIUI or HyperOS, this mechanism works somewhat differently than in “pure” Android, which often confuses owners.
You might think that background processes are an absolute evil that needs to be eradicated, but the system is smarter than it sounds. Autostart is not just a way to slow down your phone, but it's a necessary tool for messengers, alarm clocks and smart alarms to work properly, and if you turn off the wrong services, you risk not getting notifications or being late for a meeting.
In this article, we’ll look at how apps start on Xiaomi devices, and we’ll determine which processes are really worth limiting and which ones are best left alone, and understanding these mechanisms will allow you to configure your smartphone wisely without turning it into a brick with broken communication features.
Auto-start mechanism in MIUI and HyperOS
Xiaomi’s shells have a deep modification to the Android kernel, which includes aggressive memory management. Unlike stock versions, there is a special system service that tracks the state of RAM (RAM), when you restart your phone, the system reads the list of allowed applications and runs their main services.
It's worth understanding the difference between a frozen app and a completely stopped one. Many users think that if they swipe it, it's gone. In fact, Android often leaves processes in the cache for quick reopening, while autoruns are about services that should start immediately after the screen or system is turned on.
Technical detail
MIUI divides auto-runs into two types: explicit (permitted user) and hidden (system): the first is controlled through security settings, the second is internal shell processes that the average user should not touch, and it is the balance between these types that determines how fast your interface works.
The impact of background processes on battery and memory
Smartphone owners' biggest fear is that they're going to run out of battery power, and it's true that active processes consume the processor's resources and keep the device from going to sleep. But today's Snapdragon and MediaTek chips are able to efficiently distribute the load, and if an app is just hanging in memory and waiting for an event, it's almost powerless.
The problems begin when an application tries to keep up to date, geolocation or network, and then the background activity becomes noticeable, and if you have a lot of "heavy" auto-run programs installed, it can lead to heating of the case and shorten battery life.
- 🔋 Constantly synchronizing data to the cloud can keep the screen and processor active.
- 📡 Use of the GPS In the background for tracking is one of the most energy-intensive processes.
- 💾 Overflow of RAM leads to more frequent unloading of active tabs and their reboot, which also wastes energy.
On the other hand, completely shutting down all background processes can lead to a paradoxical result: the system will constantly “kill” and re-run important services, which consumes more energy than their quiet memory. The optimal scenario is to leave auto-run only for messengers and system services, disabling it for games and rarely used software.
What applications can and should be turned off
The first rule of Xiaomi optimization is not to touch system components unless you are 100% sure of their purpose. Disabling system services can lead to unstable interface operation, loss of sound or inability to make a call.
First of all, look at games, stores, photo and video editing apps. They don't have to run with your phone. They should only start when you open their icon yourself. It's also worth checking out social media if you don't need instant notifications from them.
☑️ Criteria for disabling autostart
Apps are also being asked to pay special attention to by Chinese developers, who often commit intrusive advertising and hidden mining in the background, and if you notice that an unknown process is constantly active, you better find it in the settings and prevent auto-start, which will increase the security of your data.
Instructions: how to manage auto-run on Xiaomi
There's a tool in the MIUI shell to manage this, and the path to it may vary slightly depending on the firmware version, but the logic remains the same. You don't need root rights or a computer connection.
Open the standard Safety app (green lightning icon). In the menu, look for Permissions or Other Permits. There will be AutoStart. When you click on it, you will see a list of all the programs installed with switches.
Settings → Applications → All Applications → (Select App) → Other Permissions → Auto RunYou can also go from the opposite: go to Settings, select Apps, find a specific program, click Other permissions and there's a togg' autorun. It's a longer journey, but it's easy to dot.
💡
When disabling autorun for instant messengers (WhatsApp, Telegram), be sure to check the battery settings for this application and select “No restrictions”, otherwise notifications may come with a delay.
Comparison: Auto-Run vs. Battery Limits
Many users confuse autostart control with power saving settings. These are different tools. Autostart controls the start of the application when you turn on your phone. Battery restriction (energy saving) controls what the application can do while you are not using it.
With HyperOS and newer versions of MIUI, these features are integrated into a single management ecosystem, but it is important to understand the table below so you don’t get confused by terms and settings.
| Parameter | Function | Impact on notifications | Recommendation |
|---|---|---|---|
| Auto-start | Starting services at system start-up | High (without it, the first notifications may not come) | Enable messengers |
| Background activity | Background work with folded application | Average (affects timeliness) | Allow for important applications |
| Battery savings | Limitation of processor resources | Low (if not "strictly limited") | Use the standard regimen |
| Freeze. | Complete stop of process | Critical (no notifications will be given) | Only for games and media |
Using Hard Restriction mode in the battery settings effectively equates to completely shutting down the background even if auto-starting is allowed.The system will "kill" the process immediately after you roll up the app window.
Common errors in setting up the system
The most common mistake is to turn everything off for clean memory, as users start to massively ban auto-runs from system components like MIUI Daemon, Google Play Services, or system frameworks, leading to Play Market store errors, account sync failures, and persistent error pop-ups.
💡
Never disable auto-start for Google and Xiaomi system services, or for apps that you need instant notifications from (banks, taxis, delivery).
Another mistake is ignoring updates. Often, problems with voracious applications are solved by developers in patches. If you turn off auto-runs but don’t update a bugged application, it can still find ways to run through other processes (called startup chains).
⚠️ Warning: Disabling system components such as Security, Downloads, or Package Installation may make it impossible to install new applications or update the system.
Also, don’t rely on third-party memory cleaners from Google Play. Xiaomi’s built-in mechanisms work more efficiently. Third-party utilities consume resources themselves and often make things worse by constantly restarting their monitoring services.
