How to remove reminders in the calendar on Xiaomi Redmi 9: all ways

Reminders on the Xiaomi Redmi 9 calendar can be a real headache if they are duplicated, outdated or created by mistake. Especially annoying when the system persistently signals an event that has long since lost relevance — whether it is a one-time meeting or a weekly alarm clock that you forgot to turn off. In this article, we will analyze all possible scenarios, from removing single reminders to mass cleaning of recurring events, as well as the nuances of working with the standard MIUI calendar and Google Calendar, which users often confuse.

It’s important to understand that on Redmi 9 (as on other Xiaomi smartphones), reminders can be stored in different sources: locally in the device’s memory, in the Mi Account or in Google Account. This not only affects how you delete it, but also whether the event will return after a reboot or reset. We will look at each case separately so you can determine exactly where the problem reminder sits and how to get rid of it forever.

Why reminders are not removed: the main reasons

Before we get to the instructions, we'll look at why some events persist even after they're removed, and here are the most common reasons:

• 🔄 Cloud Sync: A reminder is linked to a Google Account or Mi Account, and after being deleted on the phone, it is restored the next time you update the data.
• 📅 Repeated Events: If an event is set as weekly/monthly, deleting one instance does not affect the entire series.
• 📱 Duplicate Calendars: Redmi 9 can activate multiple calendars by default (e.g., Personal, Workers, Holidays) and an event can exist in each of them.
• 🔄 App cache: Sometimes a deleted reminder gets stuck in the calendar cache and continues to show up until the data is cleared.

To avoid confusion, first check which calendar is used to store the event. To do this, open a reminder and look at the Calendar box, which will indicate the source (for example, “Mi Calendar” or your email address for Google Calendar).

⚠️ Note: If you delete an event from Google Calendar, it will disappear from all devices where you are logged in to the same account. For local events (without cloud binding), the changes will only apply on your current smartphone.

Method 1: Remove reminders via the standard MIUI calendar

The standard Calendar app on Redmi 9 lets you manage both local events and those synced with Mi Account.

1. Open the Calendar app** (Date and Hours icon).
2. Find the desired event in the list or go to the date when it is scheduled.
3. Tap the reminder once to open his card.
4. In the upper right corner, press three dots (⋮) and select "Delete»**.
5. If the event is repeated, the system will ask you to choose: 🗑️ «Only this event will delete only the selected copy. 🔄 «All events"** - delete the entire series (e.g. all weekly meetings).

After deleting, check if there are any events left in other calendars.

1. In the main menu of the calendar, click on three horizontal lines (☰) top-left.
2. Scroll through the calendar list and make sure the tick is only next to the right ones (for example, turn off Holidays if they interfere).

If the reminder disappears but reappears after a while, it syncs from the cloud, in which case you go to Method 3 (delete via Google Calendar).

Method 2: Remove through notification settings

Sometimes reminders continue to come even after the event is removed from the calendar, this happens if the notification was scheduled through the task manager or the Reminder app (separate from the calendar) to delete it completely:

1. Open Settings → Applications → Application Management.
2. Find the list “Calendar” or “Reminders” (if installed).

If the notification doesn’t disappear, try clearing the Calendar app cache:

1. In the Calendar app settings, click Storage → Clear Cache and Clear Data** (Warning: This will delete all local events!).

⚠️ Note: Clearing the Calendar app data will remove all local events that are not synced to the cloud. If you have important reminders, pre-export them to the file (more on this in the next section).

Method 3: Delete via Google Calendar

If a reminder is linked to a Google Account, it should be deleted via the web version or Google Calendar app, and this is true for users who sync data with other devices (such as a tablet or PC).

1. Open the Google Calendar app** (if not installed, download from the Play Store).

If the event is not deleted or returned, check the sync settings:

1. Go to Settings → Accounts and Sync → Google.
2. Select your account and make sure the switch next to Calendar is turned on.
3. If sync is disabled, turn it on and wait for the data update (it can take up to 5 minutes).

To completely clear up recurring events that are not deleted in the standard way, use the Google Calendar web version:

1. Find the event, right-click on it and select “Delete” → “All events in the series”.

💡

If a reminder is duplicated in both calendars (MIUI and Google), remove it first from Google, then from the standard calendar.

Method 4: Massive removal of reminders

If you have a lot of old events on your calendar, it's not rational to delete them one at a time.

For local events (without synchronization):

1. Go to Settings → Applications → Application Management → Calendar.
2. Click on “Storage” → “Clear Data”.

For Google Calendar Events:

1. Open the Google Calendar in your browser.
2. In the left menu, find the “My Calendars” section and click on the three dots next to the calendar.
3. Select Settings and Sharing → Delete Calendar (this will delete all events inside it!).

For the Mi Calendar events:

1. Open the standard MIUI calendar.
2. Press three lines (☰) top-left.
3. Select a calendar (such as “Personal”), click on the three dots next to it and select “Delete Calendar”**.

If you need to save some of the events before a mass cleanup, export them:

1. In MIUI Calendar: Exports are only available through backup to Mi Cloud.

What if the reminder is not removed?

If you have completed all the steps but the event continues to appear, try the following methods:

• 📱 Turn off sync: Go to Settings → Accounts and sync. Turn off sync for Google and Mi Account. Delete the event via the standard calendar. Turn sync back on.

Use a third-party app

If the problem persists, it is possible that the event is added via the Reminders app (separate from the calendar) to remove it:

1. Open the Reminders app** (bell icon).
2. Find the right reminder, swipe it to the left and click "Delete"**.

⚠️ Attention: On some firmware MIUI The Reminders app can be integrated into the Calendar, in which case check the Reminders tab inside the standard calendar.

How to Prevent Unnecessary Reminders in the Future

To avoid problems with duplicate or unnecessary events, follow these tips:

• 🔗 Turn off automatic sync for unnecessary calendars (such as Holidays or Moon Phases»).
• 📅 Use one primary calendar: Choose either a Google Calendar or MIUI Calendar and turn off the second to avoid doubles.
• 🔔 Set up notifications: In Google Calendar: Settings → Default notifications → Turn off unnecessary alerts. MIUI Calendar: Settings → Reminders → Choose only important types of events.

Clean the cache regularly

If you create repetitive events often (for example, for work or training), use tags or separate calendars for different areas of life, making it easier to manage groups of events.

• Create a work calendar for deadlines.
• A personal calendar for meeting friends.
• The Health Calendar for Exercise.

This will enable you to disable notifications for entire event categories without deleting them completely.

💡

Before removing a recurring event, always check if it is linked to other services (e.g. Mi Fit for workouts or Google Tasks for tasks).
