How to remove unnecessary programs with Xiaomi Redmi Note 4: Complete system cleanup

Xiaomi Redmi Note 4 has established itself as one of the most reliable devices of its time, but even such a device becomes slower over time due to the accumulation of digital garbage. Owners often face a lack of internal memory, which leads to interface brakes and inability to install new applications. The main reason for overflow of storage are system applications that can not be removed by standard methods, and residual files from long-forgotten games.

The Redmi Note 4 cleanup process requires caution, as the MIUI shell is deeply integrated with system processes, and removing critical components can lead to the inoperability of the gadget. In this article, we will discuss safe ways to get rid of excess software, from simple settings to advanced methods through debugging via USB. You will learn to distinguish system-critical processes from useless ballast that only consumes the resources of the Snapdragon processor.

Analysis of the occupied space and identification of heavyweights

Before you take drastic action to delete files, you need to make a detailed diagnosis of the current memory state. The MIUI shell provides built-in tools for analysis, but they don't always show the full picture of hidden caches. Go to Settings → Memory to see the basic resource allocation and understand which type of data takes up the most space.

It often turns out that the lion's share of memory is occupied by multimedia and messenger cache, not by the applications themselves. However, if the goal is to clean the programs, you should pay attention to the "Applications" section. Here you can sort the list by size and find those heavy programs that you haven't even run in the last six months. Visual analysis allows you to quickly identify candidates for removal.

💡

Before removing any programs, take screenshots of the list of installed applications so that in case of an error, you can restore the remote by name of the packages.

It’s worth noting that some system services can grow to giant sizes due to logging errors or accumulating error reports. If you see an application that takes up several gigabytes, check the details: it may be enough to clear its cache, rather than delete the program itself, this is especially true for Google Play services and the system gallery.

Standard removal through MIUI settings

The safest and most obvious method of cleaning Redmi Note 4 is to use a full-time application manager, which is suitable for removing custom software downloaded from the Play Market or Mi GetApps store. To start, go to the Settings menu → Applications → Application Management, which provides a complete list of installed software.

Select an unnecessary program from the list and click the Delete button. The system will request confirmation of the operation, warning of the loss of data of this application. If the Delete button is active (not grey), then the program is not critical to the operation of the Android operating system and can be safely uninstalled.

However, if you try to remove the system application, the button will not be available, in which case MIUI offers only the option “Disable”. Disabling hides the application icon and stops its processes, but physically the files remain in the device’s memory. This is a temporary solution that does not free up space, but helps to remove the excess from view and reduce the load on RAM.

Using USB debugging for deep cleaning

Removing embedded system applications that cannot be removed by standard means requires USB debugging mode and a computer, which allows you to send commands directly to the operating system, bypassing the limitations of the MIUI interface. First, you need to activate the hidden developer menu: go to Settings → About Phone and quickly click 7 times on the MIUI version.

Once you activate the developer menu, go to Settings → Advanced Settings → Developer and turn on the USB Debugging switch. Connect your smartphone to your computer with a cable. A request for debugging permission will appear on your phone screen — be sure to tick the “Always Allow” box and confirm the action.

You need to download and unpack the minimum set of Platform Tools on your computer. Open the command line in the tool folder and type in the adb device command to make sure your computer sees the phone. If it goes well, you'll see your Redmi Note 4 serial number on the list of connected devices.

Teams to remove system debris through ADB

Once successfully connected via ADB, you can begin removing system packets. The uninstall command looks like an adb shell pm uninstall -k --user 0 packet name. It is important to know the exact name of the package (for example, com.miui.weather2), which can be found using adb shell pm packages or specialized analyzer applications.

adb shell pm uninstall -k --user 0 com.miui.weather2


adb shell pm uninstall -k --user 0 com.facebook.katana




adb shell pm uninstall -k --user 0 com.google.android.videos

Using the --user 0 flag means that the application is only deleted for the current user, but its installation file remains in the system partition, a critical nuance because it avoids damage to the integrity of the system partition and leaves the ability to restore factory settings without flashing.

💡

Removing via ADB with a user 0 flag is safe and reversible, as opposed to completely removing root rights, which can lead to bootloop.

There is a list of packages that are highly undesirable for the stable operation of the Xiaomi Redmi Note 4, including security services, system launcher, telephony and basic frameworks, trying to remove them will cause the phone to stop loading or lose communication.

Comparison of System Cleaning Methods

The choice of cleaning method depends on your goals and level of technical training. Below is a table comparing the main ways to uninstall programs on their effectiveness and security for the device.

As you can see from the table, the ADB method is the “golden mean” for advanced users who want to make room without the risks associated with obtaining root rights. Root rights give full control, but any error can turn a smartphone into a “brick”.

For the average user who just wants to clean the Redmi Note 4, a combination of standard removal and disabling unnecessary services is fine. Deep cleaning through ADB makes sense if the phone is used as a dedicated device or if every megabyte of internal memory is in the account.

Recovery of Remote System Applications

If you delete the extra during the cleaning process or the system starts to work incorrectly, don't panic. Since we used the deletion method for the current user, you can return everything back with a simple command. USB.

Use the adb shell cmd package install-existing (Packet name) command to recover the deleted component, which forces the system to re-register the application for the current user using the installed file saved in the system.

⚠️ Note: If you have removed a critical system component (e.g. com.android.systemui), the phone may go into an endless reboot. ADB It is impossible, you will need to log in to Recovery mode and complete data reset (Wipe Data).

It is recommended to keep a text file with a list of deleted packages before starting a mass cleaning, which will quickly restore Xiaomi to work in case of problems, and it is also worth remembering that after resetting to factory settings, all deleted applications through ADB will return to their places.

Cleaning cache and residual files

When programs are removed, they often leave tails in storage — folders with remote application names, logs, and temporary files — that can be found using Xiaomi’s built-in Cleanup utility in its Security app, which is quite effective at finding obvious garbage.

For a deeper cleanup, use a file manager like MI Explorer or Total Commander. Note the root folder, which often contains directories with names of remote games or social networks. Android/data folder can also store heavy caches that are no longer needed.

Regularly cleaning the cache of browsers and messengers (Telegram, WhatsApp) can free up gigabytes of space. In the settings of these applications, there are functions “Data Use”, where you can safely delete downloaded media files, leaving the correspondence intact.
