Owners of the Xiaomi Redmi Note 8 Pro smartphone often face intrusive but aggressive optimization of the MIUI system. You open the messenger or navigator, fold them, and after a few minutes you find that the process is killed, notifications did not come, and music was interrupted. This is not a mistake of a particular device, but a feature of the shell that seeks to prolong battery life at any cost, sacrificing multitasking.
The problem is solved by complex setup, because in MIUI 11, 12, 13 or 14, multiple independent modules control the background processes at once. If you configure only one setting, the system will still forcibly complete the task, you will have to go from basic battery settings to deep system constraints to make the gadget work exactly as you want, not savings algorithms.
In this guide, we will look at all the tools available to keep programs active, including autostart settings, packet-specific power management, and hidden developer functions, and understanding how MIUI allocates resources will help you avoid sudden communication breakdowns or loss of game progress when switching between windows.
Autostart management and basic settings
The first step that any Redmi Note 8 Pro user needs to take is to set up the built-in startup manager. By default, the system prevents most third-party programs from running on their own or remaining active after they fold. This is a fundamental layer of protection that often blocks instant messengers and email clients.
To access these settings, you'll need to find a Security system app with a lightning icon. Inside the menu, select the Autoboot section. This displays the full list of installed programs, and you need to manually activate sliders in front of those that should be running all the time. Without this step, further manipulation may be useless.
- 📱 Open the Security app on the home screen.
- ⚙️ Go to the “Permissions” section or find the “Outload” item».
- ✅ Turn on switches for all important applications (WhatsApp, Telegram, navigators).
- 🔄 Restart the device to apply changes to system services.
☑️ Set up basic access
It should be noted that turning on autoboot does not give full right to ignore the battery limitations, but it is a prerequisite. If the program is not eligible to start, it will not be able to revive after cleaning the RAM. In some versions of the firmware, this item may be called "Permissions" -> "Autostart", which is essentially the same functional module.
Setting up energy savings for specific applications
The most critical step is to customize the energy saving policy for each important application. Global battery settings are often too aggressive, so Xiaomi allows you to set exceptions. You need to convince the system that a particular process is important and can not be completed even at rest.
Go to the Settings menu and find the Apps section. Select All Apps to see the full list of installed software. Find the program you want (like Yandex.Navigator or WhatsApp) and click on it. Inside the app menu, find the "Battery Savings" item.
The default value is "charge savings," which kills the process. You have to change that to "no limits," which removes all the blockages from the power management system, allowing the application to consume CPU and network resources even when the screen is off.
⚠️ Warning: Setting “No Limits” mode can lead to increased battery consumption if the application is actively using GPS or mobile internet in the background.
Repeat this procedure for all mission-critical services, and don't put this mode on games or video players, because they don't require a background job when you're not using them, and you can only configure messengers, work mailers and navigation systems.
Blocking applications in RAM
The MIUI-based Android operating system has a memory cleaner that the user can swipe, but there is a way to lock the application by preventing the system from unloading it from RAM during cleaning, a simple but effective method for commonly used programs.
Open the menu of running apps by swiping from the bottom up and holding your finger (or pressing the menu button, depending on the type of navigation you want), find the card of the application you want, and hold it with your finger for a few seconds, and you'll see an additional menu with icons.
- 🔒 Click on the lock icon to secure the app.
- 🧹 Now, when you clean the memory with the “Cross” button or swipe, this application will remain hanging.
- 📂 You can set up several of the most important programs at the same time.
- ⚡ This does not give 100% guarantee, but it significantly increases the priority of the process.
Why does the system kill applications anyway?
The use of locks is especially true for music players or podcasts that you listen to in parallel with other work. Combined with the "No Limits" setting in the battery, this method gives almost one hundred percent result on the Redmi Note 8 Pro.
Using Developer Mode and Background Activity
For more advanced users who don't have the standard methods, there are hidden settings in the developer menu, where you can globally change the behavior of the system with respect to background processes, and be careful, changing these settings affects the performance of the entire smartphone.
To activate the developer menu, go to Settings -> About Phone. Find the MIUI version bar and quickly click on it 7-10 times in a row until the notification "You became a developer" appears. Then a new section "Additional" -> "Developers" will appear in the settings menu.
Inside this section, scroll down to the limit of background processes. Make sure it has a "Standard Limit" or "No Limits" value. If you select a limit of 1 or 2 of the process, the system will rigidly cut multitasking.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Process limit | Standard / No restrictions | Allows you to keep more applications in memory |
| Inactive applications | Off. | Prohibits background work of unused applications |
| Background activity | Permitted. | Allows the performance of tasks in the background |
| Window animation | 0.5x or 1x | Visual effect does not affect the work of the processes |
| Waiting time | Change | Affects the speed of interface response |
💡
Don’t completely turn off background processes in the developer menu if you want to receive notifications. Complete background lock will turn your smartphone into a “ringer” without push notifications.
Also on this menu, check "Inactive Apps" to make sure it's turned off. If it's active, the system will consider the app inactive if you haven't opened it for a few days, and stop giving it access to the network and resources.
Specifics of working with messengers and navigation
Different categories of applications have their own features of work on the Xiaomi Redmi Note 8 Pro. Messengers like Telegram or WhatsApp use their own push notification mechanisms, but on the shell of MIUI they often conflict with the energy saving system. Navigators require constant access to GPS and the screen, which quickly drains the battery without the right settings.
For instant messengers, it is critical not only to remove battery restrictions, but also to allow the background to work through system notifications. Go to the app settings -> Notifications and make sure all categories (especially "Others") are enabled. Sometimes the system hides notifications, marking them as unimportant.
For navigators (Yandex.Maps, Google Maps, 2GIS), the situation is more complicated: they need permission to display on top of other windows and access to the geolocation “Always”, not only “When used”, without this, the map can go out or the route can be reset when the screen is blocked.
- 🗺️ For navigators, turn on the "No Limits" mode in the battery.
- 📍 Allow access to geolocation in "Always" mode».
- 🔔 Enable the display of notifications on the screen blocker.
- 🔋 Turn off energy savings for GPS fast-set.
If you use your smartphone as a navigator in a car connected to a charger, you can also turn on the “Do not turn off the screen” mode in the “Developers” section so that the phone does not fall asleep completely and does not lose communication with satellites.
Additional measures and system features
Sometimes even a comprehensive setup doesn’t work perfectly because of aggressive security updates from Google Play Protect or the MIUI shell itself. In such cases, resetting battery optimization settings or updating all system components through the GetApps app store helps.
Also worth mentioning is the memory extension feature, which can be available on some firmware versions, which uses some of the internal memory as virtual RAM, and enabling this feature can help keep more applications open, even though the virtual memory speed is slower than the physical one.
⚠️ Warning: Do not use third-party memory accelerators and cleaners. MIUI They often make things worse by forcibly shutting down processes you just set up and interfering with the system’s normal operation.
If nothing works, check for system updates. Xiaomi engineers regularly release patches to fix memory management errors. Go to Settings -> About the phone and check the software version's up-to-date.
💡
The main secret of stable operation on the Redmi Note 8 Pro is a combination of three actions: enable autostart, “No restrictions” mode in the battery and lock the application in the menu of running tasks.
