Synchronization in the phone Xiaomi Redmi: why you need and how to manage it

Introduction: Why Synchronization is Not Just a Cloud Backup

Have you ever lost your phone and all your contacts, photos, or notes? If so, you know how frustrating it is. Synchronization in Xiaomi Redmi smartphones is not just a buzzword from a manual, but a real lifeline for your data. But many users either don't understand how it works or are afraid to turn it on because of the myths of "personal information collection." Let's get a look at what's really behind this feature and why it should be set up correctly.

Unlike backups, which create a snapshot of data manually, syncs are automatic and real-time, which means that your contacts, calendars, or even lock screen settings will be available on a new Redmi phone just minutes after you log in to your Mi Account. But how does that work technically? And most importantly, what data is really synced and what is left only on your device?

What is synchronization in Xiaomi Redmi: a technical explanation

Synchronization in Xiaomi smartphones is the process of exchanging data between your device and the company’s servers through a Mi Account. Unlike local backup (which saves files to a memory card or PC), synchronization uses cloud storage with encryption.

• 🔄 Automatically update data on all devices associated with a single account (for example, if you add a contact to Redmi Note 12, it will appear on Redmi 10 too).
• ☁️ Recover information when changing phone or after resetting settings.
• 🔒 Protect data from loss when the device is stolen or broken.

It's important to understand that synchronization is not the same as a full backup, for example, it doesn't store:

• 📷 Photos and videos (for this there is Mi Cloud Gallery or Google Photos).
• 🎵 Music and uploaded files.
• 📱 Installed applications (only a list of them for quick reinstallation).

Technically, the process is this: when you change data (for example, add an event to a calendar), the phone sends a request to the Xiaomi server, where the information is encrypted and stored. The next time you connect to the Internet, other devices with the same account receive updated data, which is similar to how Google Sync works, but with integration into the MIUI ecosystem.

What data synchronizes Xiaomi Redmi: the full list

Not everyone knows what exactly is saved in the Mi Account cloud. Depending on the phone model (such as the Redmi Note 13 Pro+ or POCO X6) and the MIUI version, the list may vary slightly, but the basic set usually includes:

Important: SMS and call history sync is disabled by default in recent versions of MIUI due to tightening of privacy policy, and to enable it, you need to manually activate the option in the account settings.

It is also worth noting that some data are only synchronized when the following conditions are met:

• 📶 Wi-Fi connection (for large volumes, such as attachment notes).
• 🔋 Battery charge above 20% (so as not to drain the phone in the background).
• 🕒 Activity within the last 30 days (if the phone is not used for a long time, sync will be suspended).

How to turn on or off sync on Xiaomi Redmi: step-by-step instructions

Synchronization control in MIUI is intuitive, but hidden in the back of the settings. Here's how to find and configure this feature:

1. Open Settings (the gear icon on the main screen).
2. Go to Accounts and Sync (or Mi Account depending on the MIUI version).
3. Select your Mi Account (if not authorized, sign in with email/phone and password).
4. Slip on the item Data Synchronization or Mi Cloud.
5. Move the slider to the On position for general data or select specific categories (contacts, calendar, etc.).

If you need to turn off the sync completely, just move the main slider to the off position.

Save important contacts manually (export to.vcf)

Make sure photos are uploaded to Google Photos or another cloud service

Write down passwords from apps (if they are synced through Mi Account)

Check if you are using Mi Notes for important notes

-->

⚠️ Warning: Disabling contact sync will prevent new numbers added to your phone from being stored in the cloud, and if you reset or replace your device, you will lose them forever unless you back up manually.

For Redmi models with MIUI 14+ (e.g. Redmi K60 or POCO F5), the path may be slightly different:

Settings → PaSSWORD & SECURITY → Mi Account → Data Synchronization

Synchronization problems on Xiaomi Redmi: causes and solutions

Sometimes synchronization is not correct: the data is not updated, errors occur or the process freezes. Here are the most common problems and ways to solve them:

If the problem is not solved by standard methods, try:

1. Sign out of your Mi Account and log in again.
2. Clear the cache of the Mi Cloud application in Settings → Applications → Application Management.
3. Reset network settings to Settings → Connections and Sharing → Network Reset.

⚠️ Note: If after resetting the phone asks for the old password from Mi Account, but you do not remember it, you can restore access to data only through official support Xiaomi.

💡

If synchronization is slow, try turning on Traffic Saving mode in the Mi Cloud settings, which will speed up the process by compressing the data you transmit.

Sync vs Backup: What’s Best for Xiaomi Redmi

Many users confuse synchronization and backup, but these are two different processes with different goals.

So what do you do? The ideal is to use both methods:

• 🔄 Synchronization – for quick access to current data (contacts, calendar).
• 💾 Backup – to fully restore the system after resetting or replacing the phone.

For example, if you upgraded the Redmi Note 12 Pro to a new version of MIUI and something went wrong, backing up all settings and apps will help you get back, and syncing ensures that your contacts are available on the new phone right after you log in.

💡

Synchronization does not replace backup! it does not save photos, music or installed APK-For complete data security, use both methods.

Security and privacy: Should you be afraid of synchronization Xiaomi

One of the most common fears users have is that Xiaomi is leaking personal data through synchronization, and let's see if this is justified.

1. Data encryption: All data transmitted to Mi Cloud servers is encrypted using TLS 1.3 (the same standard used by banks and payment systems), which means that even if an attacker intercepts traffic, it will be extremely difficult to decrypt it.

2.Server Storage: Xiaomi servers are located in several countries, including Singapore and India.For European users, GDPR rules apply that restrict access to data.

3.What Xiaomi knows: The company does collect metadata (e.g., phone model, MIUI version, feature usage frequency), but does not have access to the content of your notes or contacts.

If you are concerned about privacy, here is what you can do:

• 🔐 Use two-factor authentication for Mi Account (included in account settings).
• 📱 Turn off sync for unnecessary categories (such as browser or notes).
• 🌐 For critical data (such as work contacts), use alternative services like Google Contacts or ProtonMail.

⚠️ Note: If you sell or transfer your Redmi to another person, be sure to log out of Mi Account and reset settings (Settings) → The phone. → Otherwise, the new owner will be able to access your synchronized data!
