Xiaomi’s Health App Doesn’t Work: All Reasons and Ways to Fix It

The Health app (Mi Health or Xiaomi Health) is a key tool for Xiaomi smartphone and smart device owners that collects data from fitness bracelets, scales, blood pressure monitors and other ecosystem gadgets. But what if it suddenly stops syncing, gives out errors or does not open at all? The problem can be hidden in software failures of MIUI, and in hardware malfunctions of sensors or Bluetooth module.

In this article, we'll look at 10 of the most common reasons why Xiaomi's Health app doesn't work, from the banal lack of internet to deep firmware conflicts, how to diagnose a problem, what settings to check first, and what to do if standard methods don't work. And for owners of smartwatches, Mi Band or Amazfit, we've prepared a separate section with synchronization nuances.

Important: If you encounter a “failed to connect to the server” error (code 8004), this may indicate that your Xiaomi account has been blocked in your region – there is a solution for this case too!

1. Problems with Internet connection

The first thing to check is the stability of the Internet connection. The Health app actively interacts with Xiaomi servers to synchronize data, and even short-term interruptions can lead to failures, especially for users who:

• 🌐 Use mobile Internet with unstable signal (for example, 2G/3G subway).
• 🔄 Frequently switching between Wi-Fi and mobile data.
• 🛡️ Connected to corporate or public networks with restrictions (e.g., locking Xiaomi ports).

How to check:

1. Open your browser and try to download any site (e.g. mi.com).
2. Run a speed test (e.g., through Speedtest) If ping is above 200ms, the connection is unstable.
3. Try switching from Wi-Fi to mobile internet or vice versa.

⚠️ Attention: If you are using VPN, temporarily disable it – some Xiaomi servers block connections from certain countries VPN.

2. synchronization errors with smart devices

If the Health app opens but doesn't show data from the Mi Band, Amazfit or other gadgets, the problem is the pairing settings.

• 🔗 The device disconnected from Bluetooth due to energy saving.
• 🔄 The firmware of the bracelet or watch is outdated (relevant for the Mi Band) 5/6/7).
• 📱 On the smartphone, the “Do Not Disturb” or “Energy Saving” mode is enabled, blocking background activity.

Instructions for restoring synchronization:

Open the Settings. → Connected devices and check the status of Mi Band|Launch the Mi Fitness app (if installed) and update the bracelet firmware|Reboot your smartphone and smart device|Remove the bracelet from the list of devices and re-coat-->

For owners of Amazfit GTR/GTS:

1. Open the Zepp app (formerly Amazfit).


2. Go to Profile → My Devices.




3. Click on three dots next to the clock and select "Untie the device."




4. Repeat the pairing.

💡

If after updating the firmware bracelet data stopped showing, reset it to factory settings through the menu in the Mi Fitness app (section "Additional").

3. Failures in the Health app

The application itself may not work properly due to:

• 🗑️ A cluttered cache (especially after long use).
• 🔄 Conflict with other apps (e.g. Google Fit or Samsung Health).
• 📦 Damaged files after updating MIUI.

How to clean cache and data:

1. Go to Settings → Applications → Application Management.
2. Find “Mi Health” and select “Storage”.
3. Click on Clear Cache and Clear Data (Warning: This will remove local settings!).

If cleaning didn’t help, try reinstalling the app:

1. Remove Mi Health through Settings → Apps.


2 Download the latest version from the official Xiaomi website or via APKMirror.




3. Set the APK- file by allowing installation from unknown sources.

⚠️ Attention: On some firmware MIUI (for example, MIUI 13/14 for global version), the Health app is system-based and is not removed in the standard way. ADB: adb shell pm uninstall --user 0 But remember: this can disrupt the work of other services Xiaomi!

4. Conflicts with Xiaomi account

Errors such as “Cannot log in” or “Server unavailable” (8004, 9006) are often associated with problems in the Mi Account profile.

• 🔒 You have recently changed your password or phone number.
• 🌍 Your region in your account does not match the firmware region (for example, a smartphone on your account) MIUI China and the account is registered in Russia).
• 🚫 Account temporarily blocked due to suspicious activity.

How to check the status of your account:

1. Go to account.xiaomi.com and log in.
2. Check the Security section for blocking notifications.
3. If your account is blocked, follow the instructions for recovery (confirmation may be required). SMS email).

For users with error 8004:

5.Problems with smartphone sensors

If the Health app doesn’t capture steps, pulse, or other metrics from the smartphone’s built-in sensors, the reasons may be as follows:

How to check the performance of sensors:

1. Enter the engineering code: ##4636##.
2. Select Testing and check all sensors.
3. If the sensor is not responding, repair may be required.

💡

On Xiaomi smartphones with Snapdragon processors (like the Redmi Note 10 Pro), sensors are often turned off due to aggressive energy saving. Add the Health app to battery exclusions!

6.Influence of custom firmware and root rights

If you use unofficial firmware (LineageOS, Pixel Experience) or get root access, the Health app may not work properly due to:

• 🔧 Lack of Xiaomi system services (e.g. MiPush Framework).
• 🛠️ Conflicts with Magisk or Xposed modules.
• 🔒 Blocking functions due to modified build.prop.

Solutions for users with root rights:

1. Install Magisk: "Mi Health Fix" (available in the Magisk repository).


2. check the file /system/build.prop for strings:




ro.miui.region=...




persist.sys.miui_region=...




If they are not available, add them (e.g. ro.miui.region=RU).




3. Reset the device.

For custom firmware owners:

If you encounter an error called “Device not certified”, try:

• 🔄 Install official firmware through the Mi Flash Tool.
• 📱 Use alternative applications (e.g. Google Fit or Health Sync).

Hardware malfunctions

If none of the software methods worked, the problem may be a physical breakdown:

• 📡 Bluetooth module damaged (often after falls or moisture).
• 🔋 The antenna is malfunctioning. Wi-Fi/Bluetooth (relevant to Redmi 9A/9C and other budgetary models).
• 💔 Cracks on the motherboard (lead to unstable operation of sensors).

How to diagnose a hardware problem:

1. Connect another Bluetooth device (e.g. headphones) if it doesn't work, the module is a problem.
2. Check if the top of the smartphone is heating up (there is a Bluetooth chip).
3. Run a leakproofness test (for example, using the Water Damage Test app).

⚠️ Note: If your smartphone falls or comes into contact with water, don’t try to disassemble it yourself! IP53 (for example, Poco X3 Pro) protection against moisture is minimal and unprofessional repairs may aggravate the breakdown.

8. MIUI Updates and Server Glitches

Sometimes the Health app stops working after the MIUI update or because of problems on Xiaomi servers.

• 🔄 After updating to MIUI 14 missing a section of sleep data.
• 🌐 Xiaomi servers are not available in your region (relevant for users from sanctioned countries).
• ⏳ Synchronization freezes at the stage of “Updating data».

How to check the status of servers:

1. Visit the Xiaomi status page: status.mi.com.
2. Check forums (such as 4PDA or XDA-Developers) for complaints from other users.

If the problem is the update:

1. rollback to the previous version of MIUI:


Download the firmware from the Xiaomi Firmware website.




Use the Mi Flash Tool for downgrade (Warning: This will reset all data!).




2. Waiting for a patch:




Xiaomi usually issues fixes within 1-2 weeks of mass complaints.

💡

If you have lost your data from past periods after the update, check your backups in Settings → Xiaomi Account → Cloud → Backup. Recovery is possible within 30 days.
