Many Xiaomi and Redmi smartphone users are faced with a device that starts to heat up and the battery is rapidly melting for no apparent reason. Often the culprit is the background mode in which applications run, even if you are not using them at the moment. MIUI and HyperOS have advanced memory management mechanisms, but sometimes they need to be manually adjusted to achieve maximum autonomy.
Understanding how the operating system works allows you to manage CPU resources efficiently. Unlike simple closing buttons, completely turning off background activity requires access to hidden or advanced settings, especially for owners of Redmi Note and Xiaomi Mi models, where the number of preinstalled services can be large.
In this article, we will discuss in detail all available methods for limiting the operation of programs in the background, you will learn how to configure automatic cleaning, use energy saving modes and apply engineering codes to deep optimize the system.
Analysis of resource consumption through battery settings
The first step is to diagnose, and you need to know exactly which app is using the most power in the background. Standard Android tools provide detailed statistics that you can't ignore.
Go to Settings → Battery and Performance, and this shows you the charge graph of the last 24 hours or 10 days. Note the app list: if a program you haven't actively used is at the top of the ranking, it's actively running in the background.
⚠️ Note: Systemic processes such as MIUI Daemon or Google Play Services, which can consume resources when synchronized. Don't force them to unnecessarily, it can disrupt notifications.
To get more information, click on the specific app in the list, and you'll see a window that's broken down by time: screen time and background activity, and that's the second parameter that we're most interested in, and if the background consumption is more than 50 percent of the total consumption, you need intervention.
Modern versions of Xiaomi’s shells allow you to see not only the flow rate, but also the frequency of awakenings. This is a critical parameter for identifying alarm clocks that keep the processor from going to deep sleep. Eliminating such troublemakers is the key to long work without recharging.
Setting restrictions for specific applications
The most effective way to remove the background is to customize the restrictions for each suspect, and MIUI algorithms allow you to flexibly manage the behavior of the software without removing it completely.
From the battery menu, select the problem app and find Background Restrictions. There are three options available: "No Limitations", "Restrict Background Activity" and "Strict Restrictions". For social networks that don't need instant notifications, choose the latter option safely.
- 📱 No restrictions: the app works fully, notifications come instantly, but the battery is consumed faster.
- 🛑 Limit: The system can unload the application from memory 15 minutes after folding.
- ⚡ Hard Limit: Background processes are blocked immediately, notifications may not arrive before the program is opened.
Also worth paying attention to AutoRun. Many users forget that banning background activity does not always prevent an application from running with your phone. Follow the Settings → Apps → AutoRun and disable all unnecessary services.
☑️ Checklist of application optimization
Remember that for instant messengers (Telegram, WhatsApp) severe restrictions can lead to the loss of important messages. Use the "No Limits" feature only for those programs that should work always, and for others apply strict control.
Use of energy saving regime
The global method of stopping all unnecessary processes is to activate energy saving modes. Xiaomi and Redmi smartphones have an intelligent system that decides which processes to stop.
In Battery and Performance, you'll find a mode-select slider: Switching to Power Saving or Ultra-Saving automatically applies a set of rules that prohibit background activity for most applications. It's a temporary but powerful solution.
| Mode of work | Influence on background | Screen brightness | Synchronization |
|---|---|---|---|
| No restrictions. | Total freedom | Maximum | Active. |
| Balanced | Standard cleaning | Automobile | Scheduled. |
| Saving energy | Restriction after 15 minutes | Reduced. | Rarely. |
| Ultra-savings | Only the elect. | Minimum | Disconnected. |
There is also a Sleep in Your Pocket feature, or smart modes that can be set to schedule, such as at night the phone can automatically go into austerity mode, turning off background internet and GPS for all programs except the alarm clock.
Secret Battery Settings
This is an ideal option when there is no charger at hand, but you need to stretch as long as possible.
Managing through the Developer Menu
For advanced users who want to gain full control of the system, there are hidden developer settings, where you can force background processes to stop, which is especially useful on older models with low RAM.
To activate this section, go to Settings → About Phone and quickly click on MIUI or HyperOS 7 times. After the message “You became a developer” appears, go back to the main settings menu and select Advanced Settings → For Developers.
We're interested in the Appendix section, and here are the key parameters:
- 🔍 Background Process Limit: allows you to set a hard limit (e.g. no more than 2 processes).
- 🚫 Do not remain active: destroy activity immediately after the user leaves.
- ⏸ Background Process Check: Forcedly Stops Processes When the Screen is Off.
⚠️ Note: Setting a back-end limit in either "0 processes" or "No processes" can cause system failures, loss of unsaved data in open applications, and navigation problems.
Using the Do Not Stay option makes multitasking impossible, so when you switch between apps, they will restart each time, which radically reduces battery consumption, but worsens the user experience by making the phone jig.
It is recommended to use these settings with caution, testing the impact on specific use cases. For the average user, standard battery settings are enough, but for older devices (Redmi 9A, Xiaomi Mi 8) this can be a salvation.
Third-party tools and application freeze
If there are not enough system tools, specialized "freeze" utilities come to the rescue. Unlike conventional closing, freezing completely stops the application's executable code, turning it into just a shortcut on the desktop until manually run.
One of the most popular and secure tools is the SuperFreezZ app, or the built-in features in some launchers, which is to use adb or root permissions to force packets to stop.
The setup process usually looks like this:
- Install the freezer app.
- Give him the necessary permissions through Settings → Special features.
- Add to the freeze list all the apps that are not needed all the time.
- Set up automatic freezing when the screen is turned off.
💡
Use it. ADB-commands for deep freezing of system applications Xiaomi, which can not be removed by standard methods. This requires a connection to the computer, but gives maximum effect.
There are also quick freeze widgets that allow a single tap to “sleep” all the programs you choose before bedtime or an important meeting, ensuring that no notification pops up and wakes up the screen.
It should be borne in mind that aggressive freezing can conflict with the notification system Google Play and MIUI. If after installing such utilities stopped coming calls in messengers, add them to the white-list within the optimizer program.
Radical Methods: ADB and Debugging
For users ready for the experiment, there is a method of disabling background services via computer and debugging via USB.This allows you to remove or disable even Xiaomi system components that consume resources.
You'll need a computer, USB-cable and installed platform ADB. After the debugging is activated, USB on the phone (Settings) → For developers → Debugging by USB) connect.
adb shell pm disable-user --user 0 com.miui.analytics
adb shell pm disable-user --user 0 com.miui.msaThese commands disable MIUI analytics and advertising services, which often work in the background, but beware: disabling critical system packages (such as com.android.phone) can cause a smartphone to fail.
Before executing any commands via ADB, it is strongly recommended to make a full data backup.Restore the system after erroneously disabling key components may require flashing the device via Fastboot.
💡
Using ADB is a powerful tool, but it requires technical literacy: A single-team error can turn a smartphone into a brick or require a factory reset.
Once the commands are executed, the change takes effect instantly, and to get it back, the pm enable command is used, which is the most effective method for dealing with embedded adware and telemetry.
