7 Reasons Why Huawei Band 6 Is Shutting Down From Xiaomi Phone – and How to Fix It

If your Huawei Band 6 is permanently disconnecting from a Xiaomi phone — Redmi Note 10, POCO X3 or any other model — the problem is not a random failure, but a system conflict. Users face this regardless of the version of MIUI: the bracelet is connected for a few minutes, then disappears from the list of devices again, and notifications come with a delay or do not come at all. 80% of cases are not the hardware fault, but the software settings that can be fixed without contacting the service.

We analyzed the user reviews, technical forums and documentation of Huawei Health to highlight the 7 The article provides step-by-step instructions for each of these, including hidden settings. MIUI, We will pay special attention to the conflict of Xiaomi's energy-saving algorithms with the Bluetooth Low Energy protocol (BLE), It can cause the bracelet to fall asleep in the background, and it can also explain why the problem is worse after the updates. MIUI 13/14 and how to get around it.

1. Energy saving conflict MIUI protocolly BLE

The main reason for the outages is aggressive background optimization in MIUI. The system automatically suspends Bluetooth applications and modules if they are not actively used. For the Huawei Band 6, which exchanges data in the background via BLE (Bluetooth Low Energy), this is tantamount to a “communication breakdown” and the problem is typical even for flagship models Xiaomi 12/13.

How it manifests itself:

🔄 The bracelet is connected, but after 5-15 minutes the connection is broken.
📱 In the list of Bluetooth devices, Band 6 is displayed as “unconnected”, although it was previously paired.
⚡ Bluetooth badge in the curtain MIUI flashes, signaling repeated connection attempts.

The solution is to disable optimization for Huawei Health and set exceptions for the Bluetooth module. Importantly, the standard addition of the application to “autostart” in MIUI does not solve the problem completely, you need to change the settings in depth.

Open Settings → Applications → Application Management

Find Huawei Health and select Permits → Other Permits

Enable Auto Start, Background Activity, Exact Location

Go to Settings → Battery and Performance → Battery Management

Select Huawei Health and Set Up a No Limits Regime

Open Settings → Connections and Sharing → Bluetooth

Click on three dots in the upper right corner and select Bluetooth Developer Mode

Turn on Debugging. BLE and Keep the connection in the background-->

⚠️ Attention: After update MIUI 14 Way to Settings Bluetooth Developer Mode has changed. Now it's hidden: to activate it, you need to 5 times click on the Bluetooth version in the Settings menu → The phone. → Version. MIUI.

2. Incompatibility of Bluetooth versions

The Huawei Band 6 uses Bluetooth 5.0 BLE, while Xiaomi’s budget models (such as the Redmi 9A or POCO M3) are equipped with Bluetooth 4.2 modules. The difference in protocols leads to “packet loss” of data, which can spontaneously turn off the bracelet, especially when the network is high (for example, during the synchronization of sleep data or training).

You can check the Bluetooth version on Xiaomi through the engineering menu:

Open the Phone app and type ##4636##.
Select Phone Information.
Scroll to the Bluetooth block, and the protocol version will be specified there.

If the version is below 5.0, there are two options:

📱 Update the phone’s firmware (in some cases, Xiaomi adds support for new protocols via the phone’s new hardware). OTA-update).
⚙️ Manually limit the frequency of data synchronization in Huawei Health (for example, disable automatic download of sleep data).

Xiaomi model	Bluetooth version	The risk of blackouts	Recommendation
Redmi Note 10/11	5.1	Low.	Update Huawei Health to the latest version
POCO X3/X3 Pro	5.0	Medium.	Turn off background optimization (see Section 1)
Redmi 9A/9C	4.2	High-pitched	Use manual synchronization
Xiaomi 12/13	5.2	Low.	Check the energy saving settings

3.Grashes in Huawei Health app

Huawei Health is often a source of problems due to:

🐞 Unstable updates (e.g. version 12.0.1.300 caused bracelets to be shut down massively).
📥 Conflict with Google Services (on phones without Google) GMS, For example, Xiaomi for the Chinese market).
🗃️ Cache overflows (with long use without cleaning).

The first thing to do is reinstall the application from an official source:

Remove Huawei Health through Settings → Apps.
Download the latest version from AppGallery or Google Play (for global firmware).
When you first start, don’t sync with Huawei ID if you have a Xiaomi phone – this reduces the number of background processes.

If the problem persists, clear the cache of system services:

Settings → Applications → Application Management → Three points (menu) → Show system → Find “Bluetooth” and “Huawei Health Service” → Clear the cache

💡

After reinstalling Huawei Health, don’t sync your data with old backups – this can carry configuration errors that will shut the bracelet down.

5. Conflict with other Bluetooth devices

Xiaomi phones have a limit on the number of simultaneously connected phones BLE-devices (usually no more than 3-4:

🎧 Wireless headphones (AirDots, Sony) WH-1000XM4).
🎮 Gamepad (Xiaomi Game Controller, DualShock 4).
🚗 Car radio with Bluetooth.

The bracelet will be turned off first, as it has the lowest priority.

Decisions:

🔗 Disable unnecessary devices manually through Settings → Bluetooth.
📵 Turn on In the Plane mode for 10 seconds, then activate Bluetooth again – this will reset the connection queue.
🔄 In Huawei Health, turn off automatic sync and manually start it when other devices are not nearby.

How to check the priority of Bluetooth devices in MIUI

V MIUI There is no direct interface to manage priorities, but you can use it. ADB-Team: Adb shell dumpsys bluetooth_manager In the output, look for the connectedDevices block - devices are listed in order of priority (the first in the list has a).

Hardware malfunctions: battery and antenna

If all the software methods did not help, the problem may be:

🔋 Bloated bracelet battery – when physical pressure is placed on the Bluetooth antenna, the signal becomes unstable.
📡 A damaged antenna (e.g. after falling or contacting water, despite a claimed 5) ATM).
🔌 Oxidized charging contacts – the bracelet doesn’t charge to the end and the power controller shuts down Bluetooth to save energy.

How to diagnose:

Check if the back cover of the bracelet is swollen (compare with photos of the new device).
Connect Band 6 to another phone (not Xiaomi) – if the problem persists, the iron is to blame.
Look at the charging indicator: if it flashes red when connected to the mains, it is a sign of a battery failure.

Temporary solution for a bloated battery:

🛠️ Carefully remove the back cover (use a plastic shoulder blade) and check if there is any bloating.
🔋 If the battery is deformed, do not use the bracelet - it is dangerous.

💡

If the bracelet turns off when you move your hand (for example, while running), it is almost always a sign of damage to the antenna, in which case it will cost less to buy a new device (replacing the antenna is worth it). ~1500–2000 ₽).
