Owners of the popular Xiaomi Redmi Note 4 smartphone often face the issue of optimizing the operating system, overflowing with pre-installed software. The standard MIUI shell installed in the factory contains many components that may not be necessary for the average user in everyday use. Removing excess “garbage” allows not only to free up precious internal storage, but also to reduce the load on the processor, which is especially important for this device, released several years ago.
The cleaning process requires caution and understanding the structure of the Android system, as rash actions can lead to unstable work of the gadget or even to a “brick”. In this article, we will discuss in detail what packages can be eliminated, what methods exist and how to avoid critical errors. You will get comprehensive information about the safe cleaning of system partitions without the need for root rights in most cases.
Analysis of pre-installed MIUI software
MIUI is famous for its functionality, but also for its abundance of built-in services, which many users call bloatware. The Redmi Note 4 has a lot of Google and Xiaomi apps installed by default, which run in the background, consuming RAM and battery power. Understanding what exactly takes up space is the first step to competent optimization.
Not all system processes are equally important to the functioning of the phone: some are responsible for basic communication functions, others are responsible for proprietary chips of the manufacturer, and others are simply advertising modules or backups of standard programs.
It’s worth noting that standard Android tools can’t remove most system applications, requiring access to deeper layers of the system, which is usually provided through USB debugging or superuser rights, but even without deep interference with system files, it can make life much easier for a device.
Safe to remove system components
There is a list of packages, the removal of which in most cases does not affect the stability of the Xiaomi Redmi Note 4. These components often duplicate the functionality of third-party counterparts or are used extremely rarely in our latitudes. Disabling or uninstalling such elements is a safe way to improve performance.
First, look at the various cloud storage services if you don’t use them, as well as Google’s standard apps, which can be easily replaced by lighter ones from the Play Market, and Xiaomi’s specific advertising or analytics services are often superfluous.
Technical names of packets for removal
Below is a list of the main removal candidates that can be eliminated without fear:
- 📦 Mi Cloud is a cloud storage service that often duplicates Google Photos and Drive features.
- 📦 Mi Video is a standard video player that can be easily replaced by a video player. VLC or MX Player.
- 📦 Music – built-in player, often containing advertising modules and unnecessary permissions.
- 📦 Themes – a theme store if you don’t plan to change the visual style of the system.
- 📦 Calculator, Compass, Scanner – standard utilities that can be replaced with more functional analogues.
💡
Removing Google’s standard apps (YouTube, Maps, Play Music) is safe if you have alternatives or use web versions.
Applications that cannot be removed
Along with secure software, Redmi Note 4 has critical components that will cause the device to fail, and system frameworks and services provide basic phone functionality, including the ability to make calls and connect to the network.
Packages associated with the MIUI Framework and Services should be especially cautious, and even if they seem unused, they can be a dependency for other processes, and attempts to remove such components often end in an endless reboot or loss of communication.
⚠️ Never remove packages called Security, Framework, SystemUI or Provider unless you are an experienced developer and understand the consequences of your actions.
The untouchable services also include those responsible for task manager, power management and network interfaces, and the table below shows examples of processes that are strictly prohibited from being removed:
| Package name | Function | Effects of removal |
|---|---|---|
| com.miui.securitycenter | Security centre | Loss of access to settings, reset permissions |
| com.android.phone | Telephony | Inability to make calls and send SMS |
| com.miui.system | Systemic resources | Critical system failure, bootloop |
| com.qualcomm.qcrilmsgtunnel | Modem work | The network goes missing and SIM-map |
Removal methods without Root rights
For Xiaomi Redmi Note 4 owners who don’t want to get root rights and risk warranty (though this is no longer the case for the old model), there is an effective method of removing applications via ADB (Android Debug Bridge), which allows you to send commands to remove packets directly from your computer.
Before starting the procedure, you need to activate the developer mode. To do this, go to Settings → About the phone and quickly click on the MIUI build number seven times. After that, a new item will appear on the menu "Developers", where you need to turn on "Debugging by USB".
☑️ Preparation for removal through ADB
After connecting the smartphone to your computer and installing the ADB platform, you can use commands to delete. For example, the command to remove a particular packet is as follows:
adb shell pm uninstall -k --user 0 name packetThe good thing about this method is that it only removes the application for the current user, without affecting the system partition completely, which means that if you make a mistake, you can always reset the settings and return it as it was.
Use of specialized utilities
If you find the command line tinkering too complicated, there are graphical shells for ADB that make it a lot easier. One of the most popular and secure programs is Xiaomi ADB/Fastboot Tools, which is designed specifically for the brand’s devices.
These utilities automatically detect the connected Redmi Note 4 and offer a list of installed applications with security notes for their removal. The program interface allows you to uninstall selected components in one click, minimizing the risk of human error.
💡
Use the Xiaomi ADB/Fastboot Tools program from the developer szaki, as it contains up-to-date lists of secure packages specifically for Xiaomi devices.
Another option is to use file managers with access to system partitions, but this already requires root rights. Popular applications like System App Remover allow you to remove even those components that are hidden from the average user, but require caution in handling.
Recovery of Remote Components
If an application is uninstalled, or an important function is lost, you can revert it back, and if the user 0 is deleted through ADB, the application can be reinstalled without losing data.
To recover through the command line, the command is used:
adb shell cmd package install-existing name packetIf you have manually deleted files through root rights or file manager, the only way to restore the device may be to flash the device or reset to factory settings with re-installing updates, which is why you should make a full backup before any manipulation.
⚠️ Note: When you reset to factory settings (Hard Reset), all user data will be deleted, but system applications will return to their original state, as when buying.
Regular maintenance, including cleaning the cache and removing unused software, extends the life of the Xiaomi Redmi Note 4 and makes it more comfortable to use.
