Users of Xiaomi and Redmi smartphones often face a situation where the standard calendar begins to interfere with work or fills the screen with unnecessary notifications. In the Android operating system with the MIUI shell or the new HyperOS, the approach to system applications is implemented specifically, which raises questions for device owners. Simply removing the icon from the desktop does not solve the problem, as data continues to sync in the background.
In this article, we’ll take a look at all the calendar management techniques available, from removing updates completely to fine-tuning event visibility. You’ll learn to distinguish between system limitations and customization capabilities. Understanding the structure of Google and Mi Account accounts will help you clean up space and increase privacy.
We will look at not only standard settings, but also more advanced ways to work with system components, which will be useful for those who want to use alternative schedulers or simply remove redundant software.
Features of the system application Calendar on MIUI
The standard Calendar app in Xiaomi smartphones is a deeply integrated component of the system, responsible not only for displaying dates, but also for synchronizing holidays, alarm clock reminders and integration with other MIUI services. That is why the Remove button in the Application Manager is often unavailable or replaced with Remove Updates.
But there's an important difference between deleting the application's executable file and cleaning up its data: You can erase all the accumulated events, reset the settings, and roll back to the factory version. For most users, that's enough to get rid of the annoyances. Complete deletion is only possible with special tools like ADB, but it requires caution.
⚠️ Warning: Attempting to force removal of system components without proper preparation can lead to unstable interface operation MIUI or the occurrence of synchronization errors.
And it's also very closely linked to accounts, and even if you hide the icon, events can continue to come from the cloud, so the key is managing the data sources, not just the visual part of the interface, and understanding this architecture allows you to flexibly customize the device to your needs.
Hiding icons and disabling notifications
The easiest and safest way to remove a calendar for everyday use is to hide it from your desktop and disable notifications. It doesn't physically remove the app, but it makes it invisible and silent. The HyperOS and MIUI shell has built-in tools to hide applications that work more effectively than simply removing a shortcut.
To start, go to the desktop settings. Press your finger on the blank spot of the screen or use a two-finger pinch to open the editing menu. Select Settings, then find the Hide Apps option. In the list that appears, find Calendar and activate the switch. Now the app will only be available through a special code or in the hidden app menu.
- 🔒 Hiding through settings: allows you to remove the icon from public access without losing functionality.
- 🔕 Disabling notifications: Blocks pop-ups but leaves events inside.
- 🚫 Background activity restriction: saves battery power by banning work in the background.
To stop the notifications flow completely, go to Settings → Notifications and Status bar → Notification Management. Find Calendar and turn off all types of alerts. This ensures that the phone won’t distract you with sounds or vibrations. This approach is ideal for those who use third-party schedulers but are afraid of disrupting system integrity.
💡
Use Do Not Disturb mode at night so that the calendar doesn’t wake you up with reminder sounds, even if you haven’t turned them off completely.
Removing updates and cleaning up data
If a standard app doesn’t suit you with its functionality or resource consumption, you can roll it back to the factory version, which removes all user data, cache and accumulated security updates, returning the app to its original state when it first turned on the phone, often solving the problems with inflating the application.
To do this, open Settings → Apps → All apps. Search Calendar (or Google Calendar if you use it). Click the app name to enter the control menu. At the bottom of the screen, you'll see the "Delete Updates" button. Confirm the action in the pop-up window.
☑️ Check before resetting the calendar
After deleting updates, it is also recommended to clear the data. Click on Clear or Memory and then select Clear All or Delete Data. This action will irreversibly delete all local events that were not synced to the cloud. Be careful: if you have important records that you did not save in your Google or Mi Cloud account, they will be lost.
This method is useful if the application is not working correctly, freezes or takes up too much space. Once reset, it will become light and fast, although it will lose new features added in recent versions.
Account management and synchronization
Often, connected accounts are the source of extra calendar events. On Xiaomi smartphones, events can come from Google Account, Mi Account, and third-party services such as Outlook or Exchange. Deleting or disabling the sync of a particular account allows you to remove the events associated with it without affecting the application itself.
To manage event sources, open the Calendar app and click on the menu (three bars or dots). Select Settings or Calendar Management. Here you will see a list of all the accounts connected. You can tick a particular calendar to hide its events, or completely disable sync for the selected account in the system settings.
| Type of account | Where to turn off | Impact on the system |
|---|---|---|
| Settings → Accounts → Google | Gmail and Meet events will stop coming | |
| Mi Account | Settings → Mi Account | Synchronization with the cloud Xiaomi will stop |
| Exchange/Corp | Settings → Passwords and security | Work meetings will no longer be displayed |
| Local. | Inside the Calendar app | Removal from the current device only |
It's important to understand the difference between disabling sync and logging out. Signing out can affect email, Play Market, and other services. So it's safer to simply uncheck "Sync Calendar" in your account settings, which will keep you accessing other features, but remove unnecessary dates from your schedule.
What to do if the calendar is not deleted?
Using ADB to remove completely
For advanced users who want to get rid of the system application, there is a method using USB debugging and ADB tools, which allows you to remove even those applications that are hidden from the average user, but it requires connecting to a computer and executing commands on the command line.
Before you start, activate the developer mode. Go to Settings → About Phone and quickly click on the MIUI version number seven times. Then, in the Advanced Settings menu, turn on Debugging on USB. Connect your phone to your PC, install drivers and the ADB platform.
adb shell pm uninstall -k --user 0 com.android.calendarThis command will delete the calendar for the current user. The application will disappear from the system, but its installation package will remain in the system section in case of a reset. To return everything back, the reinstall command is used. Be extremely careful: removing critical system packages can lead to a “bootloop” (cyclic reboot).
⚠️ Attention: Use ADB Incorrect removal of system components can make the phone unusable without flashing.
This method is especially relevant for those who install custom launchers and third-party time planners, which allows you to free up some RAM and get rid of the background processes associated with the native Xiaomi calendar.
Alternative solutions and widgets
When you delete or hide a standard calendar, you need an alternative. Google Play offers a variety of apps that can replace the standard, advanced tool. Popular options include Business Calendar 2, DigiCal and aCalendar. They offer more flexible customization of widgets and interfaces.
Widgets play a major role in usability: standard MIUI widgets are often limited in design. Third-party apps allow you to place beautiful and informative plaques on your desktop with dates, moon phases and weather, which turns the lock screen or home screen into a powerful scheduling tool.
- 📅 Business Calendar 2: A powerful tool for business people with task support.
- 🎨 DigiCal: a great combination of calendar and weather widget with a beautiful design.
- 🔄 Google Calendar: a classic solution with perfect synchronization of Google services.
When you install a new app, the system may suggest you choose the default to open calendar links. Agree to this so that links from email or messengers automatically open in the new application. This will complete the replacement process and make using your smartphone more comfortable.
💡
Replacing a standard application with a third-party analogue is the best way to get the desired functionality without the risk of disrupting the system.
