How to delete the update log on Xiaomi and disable notifications

Xiaomi smartphone owners often face a situation where system files associated with MIUI shell updates are accumulated in the device memory or in the application list. This data can take up space, put a strain on the processor or simply annoy with constant notifications that the new firmware version is ready for installation. Deleting the update log is a standard optimization procedure that can be performed without obtaining root rights and deep interference with the system.

The MIUI Updater system mechanism stores the history of actions, download cache and version check logs. Sometimes this process starts to consume battery power or creates background loads that users want to eliminate. In this article, we will detail how to safely clean this data, disable automatic checks and regain full control of your device.

It is worth understanding that complete removal of the system component is impossible without flashing it, but cleaning its data and cache solves 99% of performance problems. Update log files can take up from 100 MB to 2 GB of disk space depending on the frequency of checks. We will look at both standard methods through settings, and more advanced methods through ADB for power users.

Why to delete update data and what it does

The main reason users are looking for a way to remove the update log on Xiaomi is to free up internal memory. Firmware files that are downloaded automatically often remain in memory even after installation or download failure.

Cleaning up the system updater’s data can help you reset errors related to boot freezes or cyclic notifications. If your phone keeps writing “Update Check” and it lasts forever, cleaning the cache is the first step you should take before taking more drastic measures.

Here are the main advantages of cleaning the journal:

• 🚀 Freeing up space in the section /data, What is critical for memory devices 64 GB or less.
• ⚡ Reduce background processor activity and reduce standby heating.
• 🔇 Complete disappearance of intrusive notifications about the new version MIUI.
• 🛡️ Improved system stability by resetting potentially corrupted temporary files.

Preparing a smartphone before cleaning system files

Before you start manipulating system applications, you need to make sure that the device is ready for the procedure. Although cleaning the cache is safe, interrupting the process or accidentally deleting important files can lead to improper operation of the settings menu.

Make sure your battery is at least 30-40%, and even if you don’t update your firmware right now, system services can be activated while you’re working with the Application Manager, and it’s also recommended that you close all background applications so that there are no resource access conflicts.

Follow this checklist before starting:

If you plan to use your computer to remove components via ADB, enable USB debugging beforehand. Go to Settings → About Phone and press 7 times on the MIUI Version until you see the words "You became a developer." Then activate the appropriate switch in the advanced settings.

Cleaning cache and data through Android settings

The easiest and safest way to remove the update log on Xiaomi is to use the built-in application manager.This method does not require a connection to a PC and eliminates the risk of accidental damage to system files, since the operating system controls the process.

Go to Settings → Apps → All apps. You can find the system component that is responsible for updates in the list, it can be called Update, Updater, or have the name of the package com.android.updater. Click on it to open the control menu.

In the window that opens, you'll see two important buttons: "Clear" and "Delete." We need to clean up. Click on "Clear" and select "Clear all data."

• 🗑️ Downloaded but not installed firmware packages.
• 📝 Journal of update history and error logs.
• ⚙️ Resetting automatic verification settings.
• 📂 Temporary files left over from previous update attempts.

After this operation, the next time you log in to the System Update menu, the phone will behave like a new one, just out of the box, it will re-check the servers for the current version and create a fresh activity log.

💡

If the Clear button is inactive, try pressing Stop first and then selecting to clean the data again.

Disabling automatic MIUI updates

Just removing the log is not enough if you want to prevent it from growing again. MIUI is the default set to automatically download updates in the background, which leads to a buildup of debris. To stop this process, you need to change the hidden settings.

Open the Update app (the MIUI logo icon) and click on the three dots in the upper right corner and select Settings.

In the update settings menu, find and deactivate the following options:

• 📶"Backup over Wi-Fi” – prohibits downloading packages without your knowledge.
• 🔔"Update Notifications – Removes annoying pop-ups.
• 🌙"Night Update – prevents patch installation when the phone is in sleep mode.

⚠️ Warning: Disabling automatic updates means you take responsibility for the security of your device. Regularly check for critical security patches manually.

There is also a hidden engineer menu in the update app, and if you quickly click 10 times on the MIUI logo in the center of the screen (in the "Update" menu), additional options such as Disable update can open, which completely blocks the system component from working until the next turn on.

Using ADB to remove system components

For advanced users who want to (radically) solve the issue, there is a method of removing or “freezing” the service pack via a computer, which requires an ADB (Android Debug Bridge) and a USB-connected smartphone.

This method allows you not only to clean the log, but to prevent the system from even running the verification process. The team is sent from the computer and operates at the system privilege level. Before you start, make sure that the PC has Xiaomi drivers and Platform Tools tools installed.

Execute the following commands in the terminal or command line:

adb shell pm disable-user --user 0 com.android.updater

This command does not physically delete the file, but makes it invisible and inactive to the current user. The system will assume that there is no update application. To return it as it was, use the command:

adb shell pm enable com.android.updater

There's also a Xiaomi ADB/Fastboot Tools graphics utility that lets you do the same thing, but through a user-friendly interface. In the Debloat section, you can find the "Updater" item and just click the delete button. This is a safer option for beginners.

Comparison of cleaning methods and their effectiveness

The choice of method depends on your goals and level of training. Standard cleaning through settings is suitable for most users, as it is safe and reversible. The method with ADB gives complete control, but requires a PC and caution.

The table below compares the main ways to manage updates on Xiaomi:

For the average user, the best option is to clean the cache every few months, plus turning off autoboot in the Update settings, enough to keep the phone running fast and the memory from getting clogged.

Possible problems and solutions

During the process of cleaning or disabling updates, users may encounter a number of typical problems, such as when the data is cleaned, the Update application may open longer than usual, as it needs to re-index files.

Sometimes the system ignores the settings and starts downloading the update again, which can happen if Xiaomi servers are forced to update security (Hotfix), in which case blocking through ADB is the only effective way.

⚠️ Note: If after manipulating system files, the phone began to discharge quickly or warm up in standby mode, return the rights to the Updater application via the Internet. ADB. Perhaps the update process “hangs” in the background and consumes resources.

Also, keep in mind that global firmware (Global) updates are less common than Chinese (China) updates, but they are more stable. Deleting a journal on a global version usually doesn’t give the same performance boost as in Chinese, where background processes are more active.

💡

Complete removal of the system component of updates is not required to speed up work - regular cleaning of the cache and disabling the autoboot is enough.
