How to remove all activities from the Xiaomi calendar

Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the built-in Calendar app is overwhelmed with unnecessary events: this can be old records left over from the previous device, or intrusive spam from third-party sites. Complete cleaning requires a systematic approach, since simply deleting records manually can take hours.

The problem often lies in the mechanisms for syncing Google and Mi Cloud accounts. Even if you delete an event on your phone, it can return the next time you connect to the network. In this article, we will discuss proven methods to help you clean up your schedule and prevent debris from appearing in the future.

There are several levels of deletion, from cleaning the app cache to completely resetting the account, and the most effective way is to combine disabling the synchronization and cleaning the application data, which allows you to break communication with the server and erase the local database. Below are the step-by-step instructions for each method.

Preparation for mass clean-up of events

Before we start radical measures, we need to do some pre-production to avoid accidentally losing really important dates, like birthdays or business meetings, and backup is a key step that is often ignored.

First, check which calendars are displayed on your device. In the Google Calendar app or the standard MIUI Calendar app, click on the menu (three bars or profile icon) and you will see a list of all the sources connected here.

• 📅 Turn off the display of social media calendars (Facebook, Instagram) if they are not needed.
• 🔒 Make sure you have access to passwords from Google and Mi Accounts.
• 💾 Take a screenshot or record the dates of important events that cannot be lost.

It's important to understand the difference between deleting an event from a device and deleting it from the cloud, and if you want to clean everything globally, you need to make changes through the web version of the service, not just on your phone.

Delete Events via Google Web Interface

The most reliable way to remove all activities at once is to use a computer and a browser. Google Calendar mobile application does not have the function “Delete everything”, whereas the desktop version allows you to manage subscriptions en masse.

Go to calendar.google.com from the same account used on Xiaomi. On the left side of the screen, look for the “Other Calendars” section. Hover over an unnecessary calendar (like “Holidays” or spam calendar), click on three dots and select “Settings and Sharing.”

Scroll down to the bottom of the "Additional Actions" section, and you'll find the "Delete" button, and if you click on it, you'll clear the entire calendar of events, and that action is irreversible for the source you choose.

⚠️ Note: Deleting the main working calendar via the web interface will erase all your records forever. Use this method only for cleanup or secondary calendars, or pre-export data.

Once you delete the site, take a Xiaomi phone. Make sure it's connected to the Internet. Open the calendar app and pull the list down for an update. All deleted events should disappear, as sync will bring the phone's state into alignment with the cloud.

Cleaning up the data and cache of the application on Xiaomi

If events are not deleted or too many to manually clean, you can resort to resetting the application itself, which removes the local database, causing the application to download the information again (or remain empty if the sync is disabled).

To perform the operation, go to system settings. Find the Applications → All Apps. In the list, look for Calendar (this can be the MIUI system application or Google Calendar).

Click on Memory or Storage, and you'll see two buttons: Clear Cache and Clear Everything (or Reset), and select Clear Everything, and the system will alert you to the loss of application data.

Once reset, the app will look like it was installed for the first time, and when you re-enter your account, events can load again if you don't turn off sync, so it's best to combine this with account management.

Managing account synchronization

Often, junk events are generated by third-party applications that require calendar access and create their own hidden schedules when installed, and to remove these activities, you need to find and disable the source.

Go to Settings → Accounts and Sync (the path may vary depending on the version of MIUI or HyperOS). This displays all the associated services: Google, Mi Account, Exchange, and others.

Click on your Google account. You'll see a list of things that sync. Find Calendar and turn off the slider. This will stop new events from downloading and remove old ones from local browsing, even though they'll stay in the cloud.

Pay special attention to accounts called "Event," "Click," or strange letter sets, often signs of a viral subscription, and removing such an account from the system will completely clear the calendars associated with it.

Combating Calendar Spam and Viruses

There is a separate type of problem when Xiaomi calendars are notified of winnings, viruses or strange events, not a virus in the classical sense, but a subscription to a public calendar received when clicking on an advertising link.

To get rid of this, open the Calendar app. Click on the menu (three bars) and select Settings. Find Event Calendars or Subscriptions, and list all external sources.

You'll see a list of links. Click on suspicious and select "Delete calendar" or "Unsubscribe." After that, the events will disappear instantly from the feed. No reboot of the phone is required.

⚠️ Warning: Never click on links inside these events (“Click to check your phone”). These are phishing sites designed to steal data. Delete the event without opening its contents.

For prevention, install an antivirus or use the built-in security scanner MIUI. Regularly check the list of installed applications for unfamiliar software that may have created this subscription.

Using third-party cleaning applications

If standard methods don't work, you can use specialized software. There are calendar management tools in the Google Play store, such as Clearer for Calendar or analogues.

These apps scan the database and suggest that you delete duplicates, past events, or all content at once, and be careful that by giving access to a third-party app, you trust it with all your personal data.

• 🛡️ Use only apps with high ratings and a lot of reviews.
• 🚫 Do not give device administrator permissions to unknown programs.
• 🗑️ After cleaning, remove the cleaning app itself.

The alternative is to use a PC and Android Debug Bridge (ADB) program, which is an advanced method that requires connecting your phone to your computer via USB and enabling debugging. The adb shell pm clear com.android.calendar team cleans the calendar data at the system level.

💡

Advice: Before using third-party cleaners or ADB-commands, be sure to make a full backup of contacts and events through export to file.vcf or.ics to be able to recover data in case of an error.

Prevention and setting up notifications

Once a successful cleanup is done, it's important to set up the system so that the problem doesn't come back. First of all, limit the application rights. When a new app requests access to a calendar, consider whether it really needs it.

Xiaomi’s privacy settings can prevent you from creating events without your knowledge, and it’s also a good idea to check the subscription list on the calendar itself regularly.

Set up notifications: leave only important reminders. Turn off push notifications from the calendar app itself if they annoy you, leaving only a visual display of events.

💡

Regularly checking the list of signed calendars and carefully reading access requests when installing new apps is the best protection against calendar spam.

Keeping your digital prostor clean will help you maintain digital hygiene. Remember that most calendar issues on Xiaomi are solved by properly managing your Google account and paying attention to your subscriptions.
