Xiaomi Redmi Note 7, which came to market as a bestseller of the middle segment, still remains in active use with millions of users. However, over time, the MIUI operating system becomes cachey, and installed programs begin to behave more aggressively, consuming resources even in a sleepy state. It is the background mode of application operation that often causes rapid battery discharge and sudden slowdowns of the interface when the device is just lying on the table.
Users often notice that the phone is heating up without visible load and the battery is melting before your eyes. This is a sure sign that the system is running a lot of processes that you do not need right now. In this article, we will discuss in detail how to correctly manage background activity to extend the life of your gadget without losing functionality.
To start with, it's important to understand that completely disabling all background processes is not always the best solution. Some applications, such as messengers or navigators, must work constantly to get notifications, and our challenge is to find a balance between autonomy and usability, blocking only the extra.
Analysis of energy consumption in MIUI settings
Before embarking on radical program-restriction measures, you need to audit the current state of the system. Xiaomi’s built-in tools allow you to determine exactly which applications consume the most power in the background. To do this, go to the Settings → Battery and Performance menu, where detailed statistics will open.
Here you'll see a list of programs sorted by the amount of charge you've spent, and look at those apps that you haven't used in a long time that still eat the battery, and often, the top of the list are games, heavy social media, or marketplaces that haven't been shut down properly.
It's important to distinguish between active use and background activity. If you open your browser for 5 minutes and it's used 10% of the charge, it's continued to execute scripts after it's folded. MIUI tags those cases, and that's the one that you need to fight first, restricting their rights.
After identifying voracious applications, take your time to remove them. In most cases, just change their settings so that they do not wake up the processor unnecessarily, and this is especially true for devices with an already worn-out battery, which can boast of the Redmi Note 7 after several years of use.
Permits and Auto-Run Management
One of the main reasons for this is that you have to auto-start, and many applications prescribe themselves to start up when you start the phone, and MIUI has a dedicated controller that you can access through the Security app.
Open the Security app, select the Permissions option, and then Auto Run. Here you will see a complete list of programs that start automatically, and it is recommended that you leave only instant messengers (if you care about instant notifications) and system services on.
- 🚫 Turn off auto-runs for games, banking apps and stores – you don’t need them every second.
- ✅ Keep only those services that need to be running all the time, such as an alarm clock or antivirus.
- ⚙️ Check the “Other permissions” tab where you can prevent apps from displaying pop-ups on top of others.
⚠️ Warning: By disabling auto-runs for instant messengers (WhatsApp, Viber, Telegram), you risk stopping receiving notifications of new messages before manually opening the application.
Also worth paying attention to location and microphone permissions: If a flashlight app or calculator requests access to GPS, it's a clear sign of resource abuse. In Redmi Note 7, you can set up "Only in Use" permissions, which will automatically turn off geolocation when the application is folded.
💡
Use Do Not Disturb at night to block background synchronization of email and social media while you sleep.
Set up background activity restrictions
The Android operating system that runs MIUI has a mechanism for restricting background activity, which is more stringent than a simple autorun, since it prevents an app from doing anything when it is not on the screen.
To activate this feature, go to Settings → Applications → All apps. Select the desired program from the list, find the Battery option and select the option No restrictions (to allow operation) or Battery Savings (to limit).
However, in the shell of Xiaomi, this item may be called differently or hidden. Alternative path: Settings → Battery and performance → Saving charge in applications. Here you can set a behavior strategy for each program separately.
☑️ Verification of energy saving settings
It’s worth noting that some MIUI system processes may ignore these settings in an attempt to optimize memory performance. If the application still doesn’t receive notifications, try adding it to the system’s exceptions or whitelist, but only for mission-critical services.
Using the Developer Mode for Control
For advanced users who want to gain full control of the Redmi Note 7, there is a Developer Menu that hides deep process management settings that are not visible in the normal interface. To activate the menu, you need to click on the MIUI version number 7 times in the About Phone section.
After activation, a new option will appear in the settings menu Additional → For developers. We are interested in the section "Applications", where you can find the setting "Background Process Limit" by default, it is "Standard Limit", but it can be changed.
| Option of limitation | Description of action | Recommended use |
|---|---|---|
| No restrictions. | The system decides how many processes to keep. | Normal use regime |
| No background processes | When folding, the application is completely closed. | Maximum battery savings |
| No more than 1 process | There is only one last application left in the background. | Testing or emergency mode |
| No more than 2 processes | Limiting the pool of background tasks | For old games or heavy tasks |
Choosing the "No Background Processes" option may seem tempting to save energy, but it will cause the music in the player to stop when the screen is off and the navigator to reset the route.

Optimization of work through the application Security
Xiaomi’s regular Security app is a powerful tool that is often underrated. In addition to antivirus, it includes memory cleanup and system acceleration features that directly affect background processes. Regular use of the Cleanup feature helps to reset the hanging processes.
There's an Acceleration section inside the app that shows what's running, and if you press the acceleration button, you force applications to close in the background, but MIUI allows you to set up the Acceleration Whitelist so that important programs don't close.
Also in the security settings, check the Privacy section, and you can see which apps have requested access to the data in the background, and if a simple flashlight has requested a contact list at 3 a.m., it definitely needs to be restricted.
- 🧹 Run a full system check regularly through the Security app».
- 🛡️ Check the Payment Protection section to make sure background processes don’t affect transaction security.
- 📊 Use the cleaning widget on your desktop to quickly reset the cache of background tasks.
⚠️ Warning: Do not install third-party accelerators and cleaners from Play Market. They create background processes themselves and often conflict with built-in optimization. MIUI, worsening.
Specifics of MIUI and background services
MIUI is known for its aggressive memory management policy, which sometimes works against the user.The system can kill the processes you want to keep active, and vice versa, keep unnecessary debris.Understanding the logic of how the Redmi Note 7 works will help avoid problems.
For example, if you listen to music through a browser and fold it, MIUI can stop playback in 10 minutes. To avoid this, you need to lock the application in memory. To do this, open the menu of running applications (swipe from the bottom up and hold), find the browser window and click on the lock in the corner.
Another important aspect is synchronizing Google and Mi Account accounts, which are constantly in the background, and if you don't use Xiaomi services, you can turn them off in your account settings, which will slightly reduce the load on the network and battery.
💡
Fixing the application in memory (lock) prevents it from being closed by the cleaning system, but does not prevent it from working in the background if this is allowed by the battery settings.
Also worth mentioning is MIUI Optimization feature in the developer menu, which can change the behavior of permissions and background processes to make them more similar to standard Android, but it can lead to unstable operation of some interface features.
