Synchronization of Xiaomi Cloud: what it is, how it works and why you need it

Have you ever lost a smartphone and all your contacts, photos, or notes with it? Xiaomi Cloud (or Mi Cloud) won't do that -- unless, of course, the sync is set up correctly. This service from Xiaomi automatically stores your data on remote servers, allowing you to restore it on a new device or after resetting. But how exactly does the sync work, what data it affects and how to manage it -- questions that often go unanswered.

In this article, we will take a look at Xiaomi Cloud sync in detail, from basic principles to hidden settings, how to enable or disable sync for specific data types, what restrictions are in place on the free rate, and why sometimes files are not synced despite a stable Internet, and how to avoid the typical errors that cause users to lose access to their backups.

If you are using a Redmi smartphone, POCO or other device MIUI, This information will help you control what goes to the cloud and how to manage it, even if you've never used Mi Cloud consciously -- it's probably already in the background.

What is Xiaomi Cloud and why you need synchronization?

Xiaomi Cloud (Mi Cloud) is a cloud storage from Xiaomi, integrated into the ecosystem MIUI. Its main task is to automatically reserve and synchronize data between devices of the same account so that you can access them from any gadget: a smartphone, tablet or even a Mi Band smartwatch.

Synchronization is different from backup in that it works in real time, for example, if you add a new contact to a phone book, it will appear almost instantly in the cloud and on all attached devices, the same goes for notes, call history, or even system settings. It's convenient, but it requires a constant connection to the Internet.

Why is this important to Xiaomi users?

• 🔄 Data security: Even if your phone breaks down or is stolen, you won’t lose contacts, photos or any other information. SMS.
• 📱 Smooth transition to a new device: when you first turn on the smartphone Xiaomi will offer to restore data from the cloud – this will save hours on manual transfer.
• 🌐 Cross-platform access: some data (such as notes or files) can be viewed through the web version of Mi Cloud from any computer.
• 🔒 Additional protection: Two-factor authentication can be enabled in the cloud, making it harder for unauthorized access.

But synchronization has a downside: it consumes traffic and battery power, and the free rate is limited to 5GB (though that’s enough for most users), and not all data is synced by default — some file types need to be manually enabled.

What data synchronizes Xiaomi Cloud

By default, Mi Cloud doesn’t reserve all of your smartphone’s content, but here’s a complete list of the types of data you can synchronize (with the amount of data you normally use):

It's important to understand that photos and videos are synced only in their original quality, unless you've changed the settings. This quickly eats up the free 5GB.

• 📁 Files from folders not selected for sync (for example, downloads from Telegram).
• 🎵 Music and audio files (except for voice messages) SMS).
• 📦 Data from third-party applications (such as WhatsApp chats or documents in Google Docs).
• 🔐 Passwords and data of banking applications (they are protected at the Android level).

💡

To save space in the cloud, enable the option “Optimized Quality” in the Mi Cloud settings before syncing photos. This will reduce the weight of files without severe quality loss.

How to turn on or off sync on Xiaomi smartphone

Synchronization is controlled through settings MIUI. Here's the step-by-step instruction:

1. Open Settings → Accounts and Synchronization.
2. Select Mi Account (if not authorized, log in).
3. Go to the Mi Cloud section.
4. Activate the Synchronization slider at the top of the screen.
5. Below, choose which data to sync (contacts, notes, etc.).

To turn off sync completely, just move the slider to the off position. However, this will not delete the data already uploaded to the cloud - it will remain on Xiaomi servers until you manually clean it.

If the synchronization is not working, check:

• 📶 Internet connection (better to use Wi-Fi for large files).
• 🔋 Battery level (at low charge) MIUI It can suspend background processes).
• 🔄 Updates MIUI (In older versions, there are cloud bugs).
• 🛡️ Traffic saving settings (c Settings) → SIM-maps and mobile networks → Saving traffic).

Free tariff restrictions and how to get around them

The free Mi Cloud account provides 5GB of storage, which is enough for most users to keep contacts, notes and photos, but if you're actively shooting videos or storing a lot of media, there's not enough space quickly.

• 📇 Contacts and notes: ~100MB.
• 📸 100 photos in original quality: ~1-2 GB.
• 🎥 5 minutes of video in the video 1080p: ~500MB.
• ☎️ Call history and SMS: ~50–200 MB.

When the place ends, Xiaomi offers:

1. Buy additional space (tariffs from 6 GB/month per month) ~$0.99 to 200GB per ~$9.99 a month).
2. Clean up unnecessary data manually through the web version of Mi Cloud.
3. Disable the synchronization of heavy files (such as videos).
4. Use compression for photos (optimized quality).

💡

If you delete files from the gallery on your phone, they will NOT be deleted from the Mi Cloud automatically, but you will need to delete them separately in the Storage Management section of i.mi.com.

There are also some unobvious ways to save space:

• 🔍 Remove old backups of system settings (they take up to 1 GB each).
• 📂 Transfer photos to Google Photos (15GB free, but with quality restrictions).
• 📱 Use Google Files to clear cache and duplicates before syncing.

⚠️ Warning: If you exceed the storage limit, new data will no longer sync, but the old ones will remain available. Xiaomi does not delete files automatically - you will have to vacate space manually.

Data Security in Xiaomi Cloud: What You Need to Know

Many users are afraid to store personal information in the cloud, and for good reason.

• 🔐 Encryption: All files are transmitted by protocol HTTPS and stored in encrypted form.

However, there are risks:

• 🕵️ If someone gets access to your Mi Account, they can download all backups.
• 📡 In theory, some governments could request data from Xiaomi (as with any cloud service).
• 🔄 When you reset your phone to factory settings, local data will be deleted, even if it is not synchronized.

To improve safety:

1. Turn it on. 2FA in the account settings (Mi Account) → Security).
2. Use a complex password (at least 12 characters with numbers and special signs).
3. Check your active sessions regularly in the Mi Cloud web version.
4. Do not store scans of documents or passwords in the cloud in plain form.

⚠️ Note: If you forgot the password from the Mi Account and did not tie email/Recovery phone, access to cloud data will be lost forever. Xiaomi doesn't provide support in such cases.
