Sync with Xiaomi Cloud: What it means and how to manage it

Have you ever lost a smartphone and all your contacts, photos, or notes? With Xiaomi Cloud synchronization, this won't happen — your data will be safe even if your device breaks or is stolen. But how does this service work, what data it stores, and is it worth using? In this article, we'll look at what Xiaomi Cloud is, how to set up sync on Redmi, POCO, and Xiaomi smartphones, and answer key security and optimization questions.

Many users mistakenly think that Xiaomi cloud is just a backup. It's actually a comprehensive service that not only saves your files, but also synchronizes settings, messages, call history and even data from smart Mi Home devices between all your gadgets. For example, if you add a contact on the Redmi Note 12, it will automatically appear on the Xiaomi Pad 6 or POCO F5, tied to the same account. But how does it work in practice and what pitfalls can meet?

What is Xiaomi Cloud and why you need synchronization?

Xiaomi Cloud is a cloud storage company from Xiaomi, integrated into the ecosystem of MIUI, HyperOS and smart devices of the brand. Its main task is to automatically synchronize data between devices of the same account in real time, and also provide backups in case of loss or reset of a smartphone. Unlike Google Drive or iCloud, the Xiaomi cloud is closely connected with branded services: Mi Account, Mi Home, Mi Fit and others.

Synchronization with Xiaomi Cloud allows:

• 📱 Automatically update contacts, SMS and call history on all devices.
• 📷 Save photos and videos in the cloud (with the ability to choose quality).
• 📝 Synchronize notes, calendars and tasks from Notes and Calendar apps.
• 🔧 Restore system settings (Wi-Fi passwords, wallpaper, sound circuits) after resetting.
• 🏠 Manage smart Mi Home devices (lamps, robot vacuum cleaners, cameras) from any gadget.

It's important to understand that synchronization and backup are two different processes: Synchronization works in the background and updates data as it changes (for example, a new contact or a photo), while backup creates a full picture of the system on a schedule or manually, which can be used to recover from a reset.

What data is synchronized with Xiaomi Cloud

By default, Xiaomi Cloud doesn’t sync all data, only the data you explicitly authorized. The full list depends on the device model and firmware version (MIUI or HyperOS), but usually includes:

Separately, it is worth noting the synchronization of data from Xiaomi smart devices. For example, if you have a robot vacuum cleaner Mi Robot Vacuum or a smart lamp Yeelight, their settings and usage history can also be stored in the cloud, which allows you to manage them from any smartphone, even if the main device is lost.

⚠️ Attention: Synchronization SMS Conflict with other cloud services (e.g. Google) can be used, if you use both services at the same time, duplicates or errors are possible.

How to enable or disable sync with Xiaomi Cloud

Synchronization is managed through the Mi Account settings to enable or disable it:

1. Open the settings on your Xiaomi/Redmi/POCO smartphone.
2. Go to Mi Account (or Xiaomi Account in the newer versions).
3. Choose Xiaomi Cloud (or Cloud).
4. Sign in if requested.
5. In the Sync section, you'll see a list of available data, activate or deactivate the switches next to the desired points.

For a more subtle setup:

• 🔄 To sync data manually, click Sync Now at the top of the screen.
• 📊 To see how much space your data takes up, go to the Warehouse.
• 🔒 To remove data from the cloud, select a category (such as Photos) and click Delete.

Connect to Wi-Fi (Sync large files consume a lot of traffic)

Check the free space in the cloud (free 5 GB)

Turn off synchronizing unnecessary data (for example, SMS if you use Google Messages)

Make sure there is enough charge on the device (the process may take time)-->

If you want to turn off the cloud completely, do so in your account settings, but remember: this will also disable access to Mi Home, Mi Fit, and other ecosystem features.

Synchronization problems and their solution

Sometimes syncing with Xiaomi Cloud is not working properly, and here are the most common problems and ways to solve them:

If the problem is not solved, try the following steps:

1. Sign out of your Mi Account and log in again.
2. Clear the cache of the Xiaomi Cloud app in the settings (Settings → Applications → Application Management → Xiaomi Cloud → Clear the cache).
3. Check if synchronization is blocked by Power Saving Mode or Battery Optimization for background activity.

⚠️ Note: If you reset your smartphone to factory settings, don’t sign in to Mi Account immediately after you turn on. First skip this step, complete the initial setup, then log in and recover data from the cloud. Otherwise, there may be a conflict of versions of the data.

Data Security in Xiaomi Cloud: What You Need to Know

Many users worry about the privacy of data stored in the cloud. Xiaomi claims that all data is encrypted during transmission and storage, but there are a few nuances:

Safety benefits:

• 🔐 Data is transmitted via a secure protocol HTTPS.
• 🛡️ Access to your account is protected by two-factor authentication (SMS Mi Authenticator App or Application).
• 🌍 Xiaomi servers are located in different countries (including Europe), which reduces the risk of data loss.

Potential risks:

• 🕵️ Xiaomi collects anonymous data about device usage (this is stated in the privacy policy).
• 📡 Some countries (e.g. China) have local data access laws.
• 🔓 If your account is hacked, the attacker will have access to all synchronized data.

To improve safety:

1. Enable two-factor authentication in your Mi Account settings.
2. Do not use simple passwords (e.g. date of birth or "123456").
3. Check active login sessions regularly (Settings → Mi Account → Security → Devices).
4. For sensitive data (such as document photos), use local encryption or third-party zero-knowledge services (such as Proton Drive).

💡

If you are selling or transferring your Xiaomi device to another person, be sure to log out of Mi Account and reset to factory settings, otherwise the new owner will be able to access your data in the cloud!

How to Free Up Space in Xiaomi Cloud

Xiaomi Cloud’s free tariff provides just 5GB of storage, which is short if you sync photos or videos. Here’s how to make space:

Cleaning methods:

• 🗑️ Remove unnecessary backups: Go to Xiaomi Cloud → Backups and delete old photos.
• 📸 Optimize photos: in the cloud settings, select Download Quality → Saving traffic (photos will be compressed).
• 📂 Remove duplicates: Use the Gallery app to find similar photos.
• 🔄 Turn off the synchronization of unnecessary data (for example, SMS or notes if you do not use them).

If 5GB is not enough, you can buy additional space:

Check if the stock is still valid before you buy – Xiaomi often offers discounts for the first months of the subscription.

💡

If you delete data from the cloud, it will also be deleted from all synchronized devices. Before cleaning, make a local copy of important files!
