Losing scheduled appointments, birthdays, and important reminders due to a smartphone reset or accidental deletion of an app is a stressful situation familiar to many Android device owners. Fortunately, Xiaomi’s ecosystem and Google’s services provide several robust levels of data protection that allow you to recover lost information in minutes.
In this article, we’ll look at all the current ways to recover, from standard cloud storage sync to local backups. You’ll learn how to avoid account conflicts and why sometimes events can be hidden rather than deleted forever.
We'll look at the nuances of MIUI and HyperOS, which may differ from standard Android, and understanding these differences will help you find the menu item faster and avoid errors when reconfiguring the device.
Checking the synchronization settings of Google Account
The most common data loss scenario is that the user simply did not turn on sync or it was suspended due to battery savings. In Xiaomi smartphones, account management is placed in a separate section of system settings. The first thing to do is make sure that the connection between your device and Google servers is active and working correctly.
Go to your phone's settings and find Accounts and Sync. This shows all authorized services. Select your Google account and check the status of sliders in front of Calendar. If the switch is off, turn it on and click Sync.
- 📧 Select the desired Gmail email address.
⚠️ Note: If after the synchronization is enabled, events do not appear during the 5-10 Just a minute, check for a stable Internet connection, sometimes it helps to reboot your smartphone.
It’s worth noting that newer versions of the HyperOS shell may have slightly different paths to settings. Now it’s often in the Passwords & Security section → Privacy → Special Permits. Make sure the Calendar app is allowed to access the network and the background activity isn’t limited by the power saving system.
Data recovery via Google Calendar in the browser
If the data on the smartphone itself is not displayed even after checking the settings, the logical step is to check the cloud storage. Google Calendar stores the history of changes, and often deleted events can be returned via the web interface. This is especially true if you accidentally deleted an entire group of events or an entire account from the device.
To do this, go to calendar.google.com from your computer or other device using the same browser that you logged in to. In the upper right corner, click on the gear icon and select Settings. On the left menu, find the General section and scroll down to Restore Calendar.
The system will suggest selecting a date to roll back the calendar state, you can choose one of the time slots offered, or you can manually specify a specific date, and once confirmed, the system will start a recovery process that can take up to 24 hours, although it usually takes much less time.
- 🌐 Go to the Google Calendar website from PC.
- ⚙️ Press "Settings" (cogs) → "Restore the calendar".
- 📅 Select the date preceding the deletion of data.
- 💾 Confirm the action and wait for the process to end.
This is the most reliable method, because it affects the server part, and even if you completely reset your phone to factory settings and log in again, the browser-retrieved events will automatically appear on your device when you first sync.
💡
When restoring through the web interface, it is better to use the desktop version of the browser, since the mobile version of the site may hide some advanced archive management features.
Using the Mi Cloud to Recover
Xiaomi, Redmi and Poco smartphone owners have access to their own Mi Cloud storage, an alternative and often deeper backup layer that is integrated directly into the system. If you used a Mi Account, your events could be stored there, regardless of Google settings.
To check for backup, go to Settings → Mi Account → Mi Cloud. In the list of available data to sync, find Calendar. If the switch is active, click on it to see the details. Here you can see the date of the last sync.
| Parameter | Description | Recommended value |
|---|---|---|
| Synchronization status | It shows whether data is exchanged. | Included. |
| Date of last update | Time to save the last copy | Current date |
| Data volume | Size occupied by events | Not critically. |
| Wi-Fi synchronization | Only through Wi-Fi. | Recommended |
If you just reset your settings, the system will prompt you to restore data from Mi Cloud when you first set up your phone. If you missed this point, you can try logging into your account through the browser on i.mi.com, go to the Calendar section and check for events there. Deleting events on the site is also possible, but recovering from the shopping cart (if you have one in your version of the interface) can save the situation.
⚠️ Warning: When recovering from Mi Cloud, there may be a conflict if there are already new events on the phone with the same names.
What to do if the Mi Cloud is full?
Local recovery and import of files.ics
Not all users trust cloud technology or have fast Internet. In such cases, local recovery remains relevant. If you have previously backed up through an embedded Security app or third-party snails, you may have a file with the.ics extension or a system archive.
To import events from a.ics file, you'll need an app. The standard Calendar from Google or Xiaomi often can open such files directly through the file manager. Find the file in the download or backup folder and click on it.
The system will suggest you select an account to add events to, which can be a local phone account, Google or Mi Account, which you choose and confirm the import, and all events from the file will be added to the corresponding dates.
- 📂 Find a backup file (usually.ics or.vcs).
- 📲 Open the file through the file manager.
- 📥 Select a target account to import events.
- ✔️ Confirm the addition of records.
If you have a full system backup made through Settings → About Phone → Backup and Restore, you can only recover calendar data. When choosing a data type to restore, tick only “Calendar” so you don’t overwrite other important settings or contacts.
☑️ Checklist before import
Solving Visibility Problems
It is often the case that data is technically restored, but the user simply does not see it. This is a classic problem of display filters. In the Xiaomi Calendar app, you can hide entire groups of events (for example, birthdays, tasks, holidays), and sometimes the desired calendar is turned off in the display settings.
Open the Calendar app and click on the menu (three bars or dots). Find My Calendars or Calendar Management. Here you will see a list of all the accounts and event types connected. Make sure that the boxes are ticked against the right items or the switches are active.
It's also worth checking the date filter. Sometimes the view settings only show "Today" or "Week" events, and the old restored records simply don't make it into your current field of view. Switch the view to "Month" or "Year" to cover a wider period.
Another reason could be time desynchronization: If the date and time on the phone are downed, events may be displayed on the wrong day or hidden. Go to Settings → Additional → Date and Time and enable automatic timing over the network.
💡
In 90% of cases, the “lost” calendar is solved by simply checking the ticks in the “My to calendars” section inside the application itself.
What to do if nothing helps
In rare cases, none of the automated methods work, which can occur when the application database is damaged or Google Play services are severely disrupted, requiring deeper intervention.
Try clearing the cache and data of the Calendar app itself. This won’t remove your events from the cloud, but it will reset the display settings and make the app re-download the entire event database from the server. To do this, go to Settings → Apps → All Apps → Find Calendar → Memory → Clear.
If that doesn't work, try removing your Google account from the system and adding it again. When you add it, the system will ask you what data to sync -- make sure that the calendar is selected. This action will force you to start a full download cycle from the server.
⚠️ Note: Before deleting your account, make sure you remember your password. Without a password, you won’t be able to add your account back and you’ll lose access to all related services.
In extreme cases, if events were deleted long ago and did not enter the Google shopping cart (where they are stored for 30 days), it is impossible to restore them using standard methods. In such situations, only specialized programs for data recovery from Android can help, but their effectiveness is not guaranteed and often requires Root rights.
