Why Honor Watches Lose Connection with Xiaomi Phone and How to Fix It

Introduction: Why the problem is relevant

Honor smartwatches and Xiaomi smartphones are a popular mix among users, but their interactions don’t always go smoothly. One of the most common complaints is that the Honor watch suddenly loses touch with the Xiaomi phone, stops synchronizing notifications or completely disconnects from the application, the reasons can be due to software failures and hardware limitations.

According to the statistics of the service centers, 30% Honor MagicWatch, Honor Watch GS The Honor Band and other brands, including Xiaomi, are linked to the unique conflicts between ecosystems. Huawei/Honor and MIUI, which are rarely covered in standard instructions.

It's important to understand that the problem isn't always the clock, and it's often the MIUI settings, the background optimization, or even conflicting applications that are to blame, and then you go through the details of the causes and solutions, from simple to advanced.

1.The conflict of ecosystems: why Honor and Xiaomi are not friends

The main reason for the unstable communication is different manufacturers with closed ecosystems. Honor (a sub-brand of Huawei) uses its own synchronization protocols optimized for smartphones on EMUI or MagicOS. At the same time, Xiaomi aggressively manages background processes through MIUI Optimization, which leads to a connection break.

Key points of conflict:

• 🔹 Bluetooth stacks: Honor often uses proprietary extensions BLE 5.2. which, MIUI It can be used as a “suspicious activity».
• 🔹 Background activity: Huawei Health or Honor Health app automatically shuts down after 5-10 minutes of inactivity.
• 🔹 Competing services: If Xiaomi has multiple fitness apps (e.g. Mi Fitness and Huawei Health), they can interfere with each other.

Interesting fact: on Xiaomi smartphones with pure Android (such as POCO F5 on global firmware), the problem is less common, which confirms that it is the optimization of MIUI that is to blame.

2. Top.-5 Causes of communication breakup and how to diagnose them

Before you start fixing, you need to identify the root of the problem. Below is a checked checklist for diagnosis:

Check the Bluetooth version on your phone (Settings → About Phone → Bluetooth version)

Make sure your watch is at least 20% charged.

Open Huawei Health and check the status of the connection

Reboot both devices

Try connecting to another phone (to rule out hardware malfunction)

-->

Now let’s look at the specific reasons:

If the cause is unclear after the diagnosis, move on to the next section - there we will consider rare cases, for example, hardware malfunctions of the Bluetooth antenna in the clock.

💡

Xiaomi phones with MIUI 14+ have a hidden setup Developer Options → Disable Bluetooth A2DP hardware offload. Its inclusion sometimes solves the problem with the communication breakdown.

Step-by-step solution: MIUI settings for stable communication

The most common cause of communication breakdown is aggressive MIUI optimization, which automatically closes background processes, including clock synchronization, and can be manually fixed:

1. Open Settings → Applications → Application Management.
2. Find Huawei Health (or Honor Health) and select Battery.
3. Set the Background Activity Switch to the No Limits position.
4. Enable AutoRun and Show notifications.

It is further recommended that:

• 🔧 Disable Adaptive Battery in Settings → Battery → Battery settings.
• 🔧 Add Huawei Health to Secure Apps (in some versions) MIUI This item is called Cleaning Blockage).
• 🔧 Enable Developer Mode and disable Background Process Limitation.

After you have set up, restart your phone and re-synchronize your watch. If the problem persists, move to the next section.

💡

Xiaomi’s MIUI 13+ smartphones have a hidden limit on the number of Bluetooth devices connected at the same time (usually 5). If you exceed it, the system begins to forcibly turn off “unnecessary” gadgets, including watches.

4.Firmware issues: When an update breaks the connection

Often, communication is broken after a MIUI update or watch firmware, for example, after the release of MIUI 14, many Honor MagicWatch 2 users experienced a clock that stopped connecting to the phone, the reason being a change in Bluetooth Low Energy (BLE) protocols.

What to do:

1. Check the firmware version of the watch in the Huawei Health app (Device Profile → Software Update).
2. If an update is available, install it. If the problem occurs after the update, try rolling back to the previous version (instruction below).
3. On your phone, roll back MIUI to the previous stable version via Settings → About Phone → System Update → Three Points → Select an update pack.

To roll back the firmware of the Honor watch, you will need:

1. Download the desired version of the software from the Huawei website (support section).
2. Connect the watch to your PC via Huawei HiSuite.
3. Manually flash the device through Recovery Mode (the instructions for each model are different).

If the rollback didn’t help, there may be a hardware problem with the new MIUI and Honor firmware, which leaves two options: wait for a patch from the manufacturer or use alternative synchronization apps (more on that in the next section).

5. Alternative ways of connecting: bypassing restrictions

If standard methods don't work, you can try to circumvent the limitations of MIUI with third-party solutions.

• 📱 Notify & Fitness: Supports most Honor models and runs more stable than native Huawei Health on Xiaomi.

Notify & Fitness will require:

1. Install the application and provide all permissions (including Special Access to MIUI).
2. In the application settings, select the Honor watch model.
3. Disable the native Huawei Health app (it may conflict).

Warning: Third-party apps may not support all of the watch’s features (such as pressure measurement or ECG on the Honor Watch GS Pro).

💡

If Honor is turned off when calling, try Notify & Fitness to turn off Call Redirect, which often resolves a communication disconnect during a call.

6. Hardware malfunctions: when the "iron" is to blame

If the software methods didn't work, the problem could be the hardware, and most often, the problem is:

• 📡 Bluetooth watch module: physical damage after falls or moisture.
• 🔋 Battery: With a discharge below 15%, the watch can switch off from the phone to save energy.
• 📱 Phone antenna: some Xiaomi models (for example, Redmi Note 10 Pro) over time, the reception of Bluetooth signals deteriorates.

How to check:

1. Connect the watch to another phone (preferably not Xiaomi). If the problem persists, the watch is to blame.
2. Check the integrity of the watch body: cracks or bloating may indicate damage to internal components.
3. Use a Bluetooth tester (such as the Bluetooth Scanner app) to check the signal strength.

If a hardware malfunction is confirmed:

• 🛠️ For watches, please contact Honor Service Center, and it costs between 1,500 and 3,000 to repair a Bluetooth module. ₽.
• 📱 For phone: try resetting network settings (Settings) → System system → Resetting settings → Network resets. If it didn't work, diagnostics in the service.

💡

The Honor MagicWatch 2 and GS 3 have hidden Bluetooth diagnostics. To run it, go to Settings → System → About and 5 times click on the Bluetooth version. The signal testing menu will appear.

7. Frequent User Errors and How to Avoid Them

Many communication problems are caused by users' incorrect actions, and here are the most common mistakes:

• ❌ Flight Mode: Even a brief switch on this mode knocks out the Bluetooth connection.
• ❌ Installation of informal firmware: custom ROM (For example, LineageOS often breaks down the work. BLE.
• ❌ Ignoring updates: if you do not update Huawei Health and watch firmware, sooner or later there will be incompatibility.
• ❌ Multi-phone connection: Honor watches don't work well with multi-connection. When you change devices frequently, sync is lost.

How to avoid problems:

⚠️ Warning: Never click Forget Device in your phone's Bluetooth settings if the watch is currently connected, which can cause the paired keys to reset and reconnect without completely resetting the clock.

Also avoid:

• 🚫 Huawei Health and Mi Fitness are used simultaneously.
• 🚫 Connecting the watch to your phone via Bluetooth manually (bypassing the app) leads to profile conflict.
• 🚫 Watches are below 10 percent, and then they go into deep economy mode and turn off the radios.

If you make one of these mistakes, reset your clock (Settings → System → Reset) and re-synchronize it with your phone.
