Xiaomi smartphone owners often encounter incomprehensible system messages or notice that some applications stop working in the background. A key element in this chain is the autostart function. This is a mechanism that determines which programs can independently activate immediately after the device is turned on or after a certain downtime.
Many users mistakenly believe that shutting down all processes will speed up the gadget, but in practice, misconfiguring MIUI or the new HyperOS causes messengers to stop sending notifications and alarms to go off. Understanding how this process works is critical to the stable operation of the Android operating system in the shell from the Chinese manufacturer.
In this article, we will explore in detail what lies behind the term, how to find hidden settings, and why Xiaomi’s security system so aggressively restricts background processes.
The essence of the autostart function in the MIUI system
Autorun is a software protocol that allows an application to initiate its work without direct user input. Unlike desktop operating systems, the Android mobile platform has strict restrictions on background activity. However, manufacturers including Xiaomi are implementing their own add-ons to tighten power control.
When you turn on your phone, the operating system loads the kernel and basic services. If the application has auto-start permission, it logs into the system task manager immediately after the interface is loaded, and this is necessary for instant messengers, email clients, and activity trackers, which need to be ready to go instantly.
But there is a downside to this, which software developers often abuse to make programs work in the background to collect analytics or display ads, which is why Xiaomi has a special security module that blocks suspicious processes by default.
⚠️ Warning: Completely disable auto-start for Google system services or shell components MIUI can lead to incorrect operation of the interface, failures in the synchronization of contacts and the disappearance of widgets on the desktop.
The system automatically analyzes the frequency of use of applications. If you rarely open a particular game or utility, the power saving algorithm can force it to stop self-starting, even if the slider in the settings is activated. This is part of the intelligent optimization of the battery.
Where to find auto-start settings on Xiaomi
The interface of the MIUI shell and HyperOS may vary depending on the Android version and the firmware region. The standard path to settings is often hidden inside the security application. To find the right switch, you need to open the Security application (green zipper icon).
Inside the security menu, select the Permissions section and then go to AutoRun. This displays a list of all installed programs with the ability to control their behavior. In some versions of the firmware, the path may look like Settings → Applications → Permissions → AutoRun.
Advanced users can also access through an engineering menu or ADB-A standard interface is enough for 99% of use cases.
☑️ Checking auto-start settings
If you can't find an application on the list, it may be hidden by the system as irrelevant, so it's worth checking the battery settings separately for a particular package, sometimes the system labels the rarely used software as "sleeping," ignoring the general permissions.
Difference Between Auto Startup and Background Work
A common mistake users make is to mix up the concepts of auto-start and background work. These are two different mechanisms, although they are closely related. Auto-start is only responsible for starting the process when the system is booted or closed completely. Background work (or working in the background) allows the application to function while you are using other programs.
You can let the application auto-run, but you can't let it run in the background, and then it starts when you turn on the phone, it gets the latest data, but it's immediately killed by the system as soon as you switch to another window, and that's true for heavy games or utilities that you don't need all the time.
The background settings are usually found in the Battery → Charge Savings menu or in the settings of a particular application in the Battery section, where you can select the modes: "No Limits", "Background Limit" or "Strict Limitation".
| Parameter | Auto-start | Background mode | Energy consumption |
|---|---|---|---|
| Starting on activation | Yes (if permitted) | No. | High (short-term) |
| Work in a curled state | No. | Yes (if permitted) | Depends on activity. |
| Receipt of notifications | Only at launch. | Real-time. | Medium/High |
| Impact on RAM | Minimum post-launch | Continuous. | Reduces autonomy |
The right configuration of these two parameters allows you to achieve a balance. For example, the navigator does not need auto-start, but the background work is critical for the route, and the messenger needs both parameters active for instant delivery of messages.
Technical details of implementation
Impact on productivity and battery
The number of processes running simultaneously directly affects the response speed of the interface. RAM in Xiaomi smartphones is often limited, especially in the budget models of the Redmi and Poco series. Dozens of active background processes lead to constant re-creation of tabs in the browser and lags when switching between applications.
On the other hand, the constant running of heavy applications eats away the battery power, the processor has to come out of the dormant state more often, and the communication modules are more active in transmitting data, this is especially noticeable at night when the phone is idle but consumes energy.
Optimizing auto-start is one of the most effective ways to extend the life of a device on a single charge, and turning off auto-starts for social networks that you don’t use for correspondence or for stores can save up to 10-15% of charge per day.
⚠️ Warning: Do not disable auto-start for system components with names"MIUI","System, Google Services Framework. This can disrupt push notifications, time synchronization, and geolocation.
There is a myth that apps need to be constantly "killed" through Task Manager. In reality, modern Android itself effectively manages memory. Forced stopping often leads to the opposite effect: the application is restarted, consuming more resources for a cold start than if it simply hung in a folded state.
Set up exceptions for important applications
For messengers (WhatsApp, Telegram, Viber) and working email clients to work properly, you need to create exceptions. The system should not restrict their activities. This is done in a few steps through the settings menu of a particular application.
Go to Settings → Applications → All apps. Find the messenger you want in the list. Go to Battery and select No Limits mode. Also make sure that the Permissions menu includes all the necessary items, including auto-start.
New versions of HyperOS have an additional layer of protection called "Memory Attachment." To activate it, open the menu of running applications (bottom-up swipe and retention), find the window of the desired program and click on the lock icon, which will prevent the system from unloading the application from RAM even when resources are scarce.
💡
Use Lock only for 2-3 of the most important applications, such as the main messenger or alarm clock, and attaching more programs will lead to artificial memory deficits and system brakes.
If notifications still don't arrive, check your traffic saving settings. Sometimes the system blocks background data transmission to save the Internet, which also prevents you from receiving messages. Allow background data transfer in the Data Use section.
Solving Typical Auto Start Problems
Users often experience a situation where settings are reset after a system update. This is normal behavior: a major MIUI update can return security settings to factory values. After each major update, it is recommended to recheck the autorun list.
Another problem is invisible processes, some applications masquerading as system processes or using multiple service processes, and if you see an unknown process name consuming resources, try searching the Internet before you turn it off.
In rare cases, resetting app settings helps. It doesn't delete personal data, but it returns all permissions to the default state. The way to reset: Settings → Apps → All apps → Three dots in the corner → Reset all settings.
💡
The main reason for the notification issues on Xiaomi is its aggressive energy saving policy, which requires manually configuring exceptions for each important app separately.
If the problem lies in a particular app that is constantly restarting and warming the phone, try clearing its cache.The accumulated debris in the cache can cause cyclical startup errors that the system perceives as an auto-start attempt.
