Xiaomi Cloud: How to clean up memory on Android

Owners of Xiaomi, Redmi and Poco smartphones often face a lack of built-in storage. When RAM is full, the device starts to work slower and new applications stop being installed. One effective way to solve the problem is to use the competent cloud service Xiaomi Cloud, which allows you to transfer data to remote servers and free up space on the physical storage of the gadget.

However, many users don’t fully understand the difference between sync and full backup. Settings errors can cause files to stay on your phone, taking up precious megabytes. In this article, we’ll detail how to properly configure cloud storage to clean up your device’s memory as efficiently as possible.

Optimization requires attention, because bad actions can lead to the loss of important contacts or photos. We will look not only at standard cleaning methods, but also at the hidden features of MIUI and HyperOS, which help manage data more flexibly. Understanding these mechanisms will allow you to forget about constant notifications of space shortages.

Principles of cloud synchronization in MIUI

Xiaomi Cloud works by constantly exchanging data between the device and the server, and when you take a photo or make a new contact, the system sends a copy of the file to the Internet, which ensures that the information is stored even if the smartphone breaks, but the file itself remains on the device, taking up space in memory.

To free up space, you need to understand the difference between file statuses. Some data may be labeled as "cloud only," but visually it's still displayed in the gallery. The key here is to properly configure sync settings in your Mi Account profile.

⚠️ Note: Before deleting any data, make sure it has successfully uploaded to the server.

It is important to note that automatic cleaning does not work for all file types, for example, contacts and notes take up minimal space, so duplication in the cloud serves security purposes rather than memory saving, with multimedia files and application backups taking the main place.

• 📸 Gallery synchronizes photos and videos in their original quality.
• 📞 Contacts and call logs are saved in text format.
• 📝 Notes and recorder are transferred along with the folder structure.
• 📱 System settings and the location of icons on the desktop.

Users often forget that deleting a file from the cloud automatically deletes it from the phone if sync is enabled, so managing the storage requires a holistic approach: first we download the data, then verify its integrity, and only then delete local copies.

Preparing your Mi Account for Cleanup

Before you start actively vacating space, you need to make sure that your account is status. Xiaomi Cloud’s free tariff provides just 5 GB of space, which may not be enough to back up your full high-resolution media files.

If your storage is crowded, sync will stop, and new photos will not be saved in the cloud, in which case cleaning the memory on the phone will be impossible through standard sync tools, you will either need to expand the tariff plan, or pre-clean the cloud itself of old garbage.

Verification of the status of the storage is done through the settings menu. Go to Settings → Mi Account → Xiaomi Cloud. This displays a visual scale of the place occupancy. If the scale is lit in red, first delete unnecessary screenshots or old videos directly from the cloud through the browser.

Also worth looking at is the firmware version. In the new HyperOS shells, the cloud management interface has been changed, some features may have been moved to the Security or Services section, and make sure your software is updated to the latest version to work properly.

Cleaning Memory Through Photo Management

The largest partition in smartphones is the gallery, and Xiaomi Cloud offers a “Free Space” feature that automatically removes images that have already been successfully uploaded to the server, the safest and fastest way to clean up.

To activate this feature, open the Gallery app and go to the Cloud tab, where you'll see sync status. If all photos are ticked, you can start cleaning. The system will determine duplicates and local copies.

It's important to distinguish between normal synchronization and storage optimization. In the second case, only thumbnails of photos are left on the phone, and high-resolution originals are stored in the cloud. When viewed, the photo is uploaded in full quality on request, which saves up to 80% of space.

⚠️ Attention: With optimisation enabled, full-size viewing of the photo will require the Internet.

If you don't want to enable optimization, you can manually select albums to sync, for example, leave the sync only for the Camera album, and leave screenshots and images from messengers only on the device or delete, which allows you to flexibly manage disk space.

💡

Use the Big Files filter in the cleanup to find heavy videos that are better transferred to your computer immediately rather than to the cloud.

Managing application backups

In addition to media files, a significant portion of the memory is occupied by backups of applications and their data. In the Xiaomi ecosystem, you can create full system backups, which are then downloaded to Xiaomi Cloud.

The backup process takes time and requires a stable connection. Go to Settings → About Phone → Backup and Restore. Select “Reservation to Mi Cloud.” Here you can select specific applications, settings, and even desktop layout.

Once the process is complete, a button will appear on the same menu to delete the local copy, which will free up several gigabytes that the backup file with the.bak extension used to take up. However, it is worth remembering that recovery from the cloud is slower than from internal memory.

• 📲 Reserve only important applications (banks, instant messengers).
• 🎮 Games are better to download from Google Play or GetApps.
• 💬 WhatsApp correspondence history is synced separately via Google Drive.
• ⚙️ System settings take up little space, but are convenient for a quick start.

Some users prefer to store full system images on a PC, so the cloud can only be used for mission-critical data such as Wi-Fi passwords and blacklist numbers, saving paid traffic and cloud space.

Working with a recorder and notes

The built-in Dictophone and Notes apps also support synchronization, recording lectures or meetings can take hundreds of megabytes, and transferring them to the Xiaomi Cloud service allows you to remove originals from your phone, leaving them available through your account.

To activate, go to the settings of a particular application. In Dictator, this is the Settings menu → Sync with the cloud. Once turned on, all new records will automatically fly to the server. Old records will need to be synchronized manually or wait for the background download.

In Notes, sync is real-time, which means you can start writing on your phone and continue on your tablet or web interface, and removing a note on one device will delete it everywhere, so be careful.

You should pay special attention to the attached files in your notes. If you have attached a photo or audio file to your note, they will also be synchronized and will occupy a place in the overall limit of the cloud.

Alternative methods and manual removal

Sometimes automatic synchronization fails and files are not deleted from the phone, and in such cases you have to manually manage files, and the standard MIUI Explorer allows you to sort files by size and date.

Find the DCIM or MIUI/cloud folder. Temporary sync cache files may remain here. Secure deletion can free up extra space, but don't delete files you're not sure about, so as not to disrupt the system.

Also effective is the use of Xiaomi’s Security app, where the Cleanup section will suggest that you delete duplicates of similar photos or large video files that have not been synchronized, a great way to find hidden data.

⚠️ Note: Manually delete system files in Android folders or MIUI This can cause the phone to function in an unstable way.

If you plan to sell the phone or make a full reset, make sure all data is moved.The Find Device feature requires the phone to be connected to the internet at least once after being reset to check the lock status.

💡

Integrated approach: The combination of cloud synchronization for important data and manual garbage removal gives the best result for freeing up memory.
