Redmi smartphone owners often face the aggressive operation of MIUI, which ruthlessly unloads running programs from memory to save battery power. This is especially true for the Redmi Note 7 model, where process optimization is the first thing. If you use messengers for work or navigators on trips, suddenly closing the application can be a serious problem.
To secure an application and keep it running, you need to make a number of adjustments in the system menu. Standard methods of managing Android memory are not enough here, since the Xiaomi shell has its own resource allocation rules. In this article, we will discuss all the available ways to help your programs stay active.
Ignoring these settings will cause notifications to arrive with a delay and background processes to be interrupted. Proper configuration of startup settings will allow you to use your smartphone as efficiently as possible. Below is a detailed guide to help you forget about spontaneously closing programs.
Reasons for Downloading Applications to MIUI
The main cause of the problems with the background work is the built-in power saving mechanism. The system analyzes user behavior and tries to close those programs that, in its opinion, are not in use at the moment. For the Redmi Note 7, this is critical, since the device does not belong to the flagship segment with a huge amount of RAM.
There is also the concept of auto-run, which works differently in the MIUI shell than in pure Android. By default, many applications are not allowed to run themselves after restarting or clearing memory. Without manual permission, the system will block their activity.
⚠️ Warning: Aggressive memory optimization can result in data loss in unfinished tasks if the application was forcibly closed by the system during an important process.
Understanding the logic of task manager helps you set up your device correctly. It seeks to extend battery life by sacrificing multitasking. Your job is to tell the system which programs are priority.
Setup of Auto-Run Applications
The first step to fixing the program is to allow it to run automatically. Without that permission, the app won't be able to activate its services after you clear RAM or restart your smartphone. This is the basic level of software control in MIUI.
To set up, you need to go to the Security app, which is Xiaomi's system tool, and inside you need to find the Permissions section and select AutoRun, and here's a list of all the programs installed, and you need to manually turn on the switchboard opposite the desired application.
☑️ Checking auto-start settings
Once you have activated auto-run, the system will know that the program is allowed to start regardless of the user's actions, but this action alone is often not enough to completely stabilize the work in the background.
💡
Turn on auto-run only for those apps you really need all the time, as this can slightly increase your battery consumption.
Managing battery restriction
The most important step is to set the battery mode for a particular application. There are three behaviors in MIUI: saving, classic mode and no restrictions. The default mode is often the saving mode, which is what causes problems.
To change your settings, go to Settings, then select Apps and find All Apps. Find the program you want in the list, click on Battery, and select No Limits. This action removes all prohibitions on background activity.
The No Limits mode choice tells the system that the application is a high priority, that it will get CPU resources and network access even when the screen is off, and that's critical for instant messengers and activity trackers.
| Mode of work | Description of behaviour | Impact on the battery |
|---|---|---|
| Battery savings | Limits background activity and synchronization | Minimum |
| Classical. | Standard behavior of the Android system | Average. |
| No restrictions. | Full freedom of action for the application | High. |
Locking in RAM
Another effective method is to lock the application in the list of recent tasks, which prevents the program from closing when using the Clean All function. The mechanism is simple: you fix the app shortcut in memory, and the system bypasses it when you clean it.
To implement this method, open the list of running applications by clicking on the menu button or swiping from the bottom up with a delay. Find the card of the desired application and pull it down (or click on the lock, depending on the version of MIUI), a lock icon will appear, indicating that the application is protected.
The application that is protected in this way will not be unloaded even if there is a lack of RAM, and the system will try to save it first, which is especially useful for navigators or music players.
💡
Locking in Task Manager is a temporary measure that is valid until the next reboot or manual unlock, so it needs to be combined with battery settings.
Advanced settings in the developer menu
For advanced users, hidden options are available in the developer menu, where you can turn off forced process terminations or change the limit of background processes, but using these features requires caution.
To activate the menu, you need to click on the build number several times in the About Phone section. Then, in the advanced settings, look for the Developer section. Here you can find the option Do not turn off the screen or settings for limiting background processes.
⚠️ Warning: Changing the limit of background processes in the developer menu can lead to unstable operation of the entire system and accelerated battery discharge.
Adb commands also allow you to flexibly configure settings, but for Redmi Note 7, standard settings are usually sufficient.

Addressing common problems
Even after you have done all the settings, there can be situations where the application still closes, which can be due to conflicting versions of MIUI or errors in the code of the program itself, sometimes helping reinstall the application with a reset of all the data.
It’s also worth checking for updates to the system and the applications themselves. Developers often release patches that improve compatibility with aggressive Xiaomi algorithms. If the problem persists, try removing updates to the MIUI Optimization component in developer mode.
In some cases, resetting the network settings or completely resetting the device helps, but these are extreme measures, and most often the problem is solved by the right combination of autostart and battery settings.
