The Xiaomi Redmi Note 5, despite its age, remains a popular device, but over time users begin to notice a decline in performance. The main reason for the slowdown lies in the excessive number of processes that continue to function in the background even when the screen is turned off. Background applications consume precious RAM and drain the battery, turning the once-fast device into a slow gadget.
The MIUI operating system installed on the Redmi Note 5 has an aggressive memory management policy, but it doesn’t always cope with modern heavy applications.You need to take control of the system into your own hands to prevent unnecessary programs from running on their own. In this article, we’ll take a detailed look at all the available methods, from standard settings to using hidden engineering menus.
Before we take any drastic measures, it is important to understand that shutting down all processes completely can disrupt messaging and system notifications. Android is designed so that some services must remain active for the device to function properly. Our goal is to strike a balance between performance and functionality, removing only the extra.
Analysis of resource consumption through battery settings
The first step to optimizing the Redmi Note 5 is to diagnose the current state of the system, and the built-in MIUI tools allow you to determine exactly which programs are most loading the processor and consuming charge, which will give you an idea of where to start cleaning.
Go to the settings menu and find the power section, which shows the performance of all the programs installed over the past day or week, and look at the applications that you rarely use but are high on the power consumption list.
You can set a customized restriction for each suspicious application, and click on the program name, and you'll see the background activity option, and if you move the slider to Restricted, the system will force you to stop the process as soon as you turn off the application window.
For such programs, it is better to choose the option "No restrictions", and for games and utilities - strictly limit their work.
Managing Auto Start and Permits in MIUI
One of the main features of the shell from Xiaomi is the presence of a separate autostart Manager, many users are unaware of its existence, although it allows you to prevent the start of applications with the phone.
To access this tool, open the standard Security app (a green shield icon). From the menu, find Permissions and select AutoRun. Here you will see a list of all the programs that try to run first.
- 🔴 Turn off autoplay for all games and entertainment apps.
- 🟢 Leave only system services and necessary messengers enabled.
- ⚙️ Check the associated permissions so that apps don’t wake each other up.
Also, there's a "Permissions" section on the same "Security" menu, where you can prevent apps from running other processes, for example, it's often the flashlight you install that tries to start a browser or app store in the background.
⚠️ Warning: Disabling Auto-Run for System Components MIUI (Mi Credit, Mi Video or Mi Music, you can disrupt standard widgets or smart screen lock features.
You should also check the "Other permissions" section, and look for the "Run in the background" option, and make sure that you don't allow unnecessary utilities to be banned, and this creates a double barrier that prevents the program from activating without your knowledge.
☑️ Checklist of auto-start optimization
Using Developer Mode to Limit Processes
To get a deeper setup, Redmi Note 5 needs to activate the hidden developer menu, a powerful tool that gives direct access to memory and process management for the Android operating system.
Activate through the About Phone menu. Find the MIUI version and quickly click on it 7-10 times in a row. Once you have become a developer, you can go to the settings.
In the main settings of the system, a new option will appear: "Additional" or immediately "For developers." Go to it and scroll down to the "Applications" section. We're interested in the "Background Process Limit" option.
Settings -> Additional -> For developers -> Background Process LimitThe default value here is "Standard Limit," and you can change it to "No More than 2 Processes" or "No More than 4 Processes," which will severely limit the number of programs running simultaneously in memory.
What happens if you set a limit of "No background processes"?
If you set a limit that is too tight, the system can start to run unstable, constantly restarting system services. For the Redmi Note 5 with its memory capacity, the optimal choice is 3-4 processes.
Specificity of the RAM on the Redmi Note 5
Understanding your device’s memory architecture will help you manage resources more efficiently. Xiaomi Redmi Note 5 came in versions with 3, 4 and 6 GB of RAM, and the approach to optimization depends on the specific modification.
The operating system reserves some of the memory for its needs, so the actual amount of free memory is always less than the declared amount. When the free space runs out, Android begins to forcibly close old applications, which causes delays when switching between tasks.
| Volume of RAM | Recommended Process Limit | Optimization strategy |
|---|---|---|
| 3GB | No more than 2. | Aggressive shutdown, disabling all visual effects |
| 4GB | No more than 3-4 | Balance between multitasking and speed |
| 6GB | Standard. | Minimum intervention, auto-start control only |
It's worth noting that constantly cleaning up memory through accelerator widgets often backfires, and the system spends resources restarting applications, which puts more strain on the processor than simply storing them in a folded state.
💡
Use the built-in Memory Extension feature (if available in your version of MIUI) to use some of the internal memory for virtual RAM, which can improve the performance of heavy applications.
If you have a 3GB version, it’s critical to keep track of which apps are hanging in the background, so system stability should be a priority, even at the expense of multitasking.
Forced Stop and Freeze of Applications
Sometimes standard methods aren't enough, and you need "brute force" in the form of forced shutdowns, which is useful for applications that are behaving incorrectly or consuming resources even after all the settings.
Go to Settings -> Applications -> All Apps. Select the program you want from the list. In the menu that opens, you'll see the Stop button. Clicking on it will complete the process.
However, once the phone is restarted, the app can start again. There is a "freeze" method to solve this problem, but it requires deeper intervention or the use of third-party root utilities, which is not recommended for ordinary users for security reasons.
A safer analogy is to use sleep mode for applications if your version of MIUI supports this feature, and when you go to sleep mode, the application is completely immobilized and can't perform any action until you open it again.
⚠️ Warning: Forced shutdown of system processes (such as Google Play Services or system) UI) It can lead to temporary interface instability, black screens, or cyclic reboots.
Use forced stop only for third-party software that you know and understand well, and for system components, it is better to use standard means of limiting background activity.
Additional tips for system optimization
In addition to managing specific applications, there are a number of common settings that will help reduce the load on the Redmi Note 5. Disabling unnecessary visuals and synchronizations can significantly speed up the interface response.
In the developer menu, find the Drawing section, and change the animation, transition and duration of the animator to 0.5x, or turn them off completely, making switching between screens instantaneous.
- 📉 Turn off automatic photo and data sync for rarely used accounts.
- 📡 Turn off Bluetooth and GPS, when not in use so that applications do not scan the ether in the background.
- 🌙 Use Do Not Disturb at night to block background notification activity.
It is also recommended to clean the app cache regularly, and accumulated temporary files can take up hundreds of megabytes and slow down the program, and this can be done through the Security -> Cleanup menu.
💡
A comprehensive approach, including limiting auto-run, setting process limits and turning off animations, gives the best result on older Xiaomi models.
Remember that no optimization can help if your phone’s internal memory is almost full. Always leave at least 15-20% of the space available for your system files and cache to work properly.
