Users of the Honor 5 smartwatch often face a connection break when connecting to Xiaomi Redmi smartphones. The problem manifests itself in various ways, from accidental Bluetooth breaks to complete loss of synchronization a few minutes after pairing. In most cases, it is not hardware malfunctions that are to blame, but software conflicts between the firmware of the devices.
Especially pronounced problem manifests itself on the Redmi shell. MIUI 12.5-14, where aggressive background optimization and restrictions on third-party apps (including Huawei Health or Honor Health) lead to forced disconnection, while the same watches with phones of other brands – Samsung, Realme – may not experience similar failures. Next, we will analyze all possible causes and ways to eliminate them, including hidden settings. MIUI, which the manufacturer does not advertise.
Important: If your Honor 5 is only disabled when you’re doing a specific thing (like a call or when you’re starting your camera), it could be a conflict with dynamic MIUI optimization, a feature that blocks background processes to save battery life, and standard tips like “reboot devices” won’t help, requiring deep system tuning.
1.Firmware conflict: why MIUI blocks Honor 5
The main reason for the unstable connection is the MIUI energy saving policy, which automatically restricts the operation of background applications, including those responsible for synchronizing with smartwatches. The Honor 5 uses the BLE 5.0 (Bluetooth Low Energy) protocol, which MIUI often perceives as an “unnecessary” background process and pauses it after 5-10 minutes without activity.
Additional factors:
- 📱 Version. MIUI 13.0.5: older builds lack protocol support GATT A server that uses a clock to exchange data.
- 🔄 Automatic switching Wi-Fi/Bluetooth: Redmi’s dual connection feature may conflict with Honor 5, If both devices are using the same channel.
- 🛡️ Protection of confidentiality MIUI: in the security settings (Settings) → Privacy mode can be enabled to limit background data for the Huawei Health application.
To check if MIUI is blocking your watch, open Settings → Applications → Application Management → Huawei Health → Battery and look at Background Activity. If it's limited, the system forcibly breaks the connection.
2.Bluetooth settings: Hidden settings that break the connection
Even if the Honor 5 watch successfully pairs with Redmi, the connection can break due to incorrect Bluetooth settings. Unlike other smartphones, Xiaomi hides some of the Bluetooth settings in the engineering menu.
Key issues:
- 🔊 Bluetooth: Honor 5 codecs are codeced SBC, but MIUI may be forced to switch to AAC, cliff-causing.
- 📶 Dual Audio Mode: If Redmi has dual device simultaneous connectivity enabled (Settings) → Bluetooth → Additionally. → Dual Audio, the watch will shut down when you try to play sound on another gadget.
- 🔄 Automatic reconnection: in MIUI 14 This feature is unstable – the clock may be “forgotten” after the phone restarts.
To fix this:
- Open Settings → Bluetooth and remove Honor 5 from the list of conjugated devices.
- Go to Settings → About Phone → MIUI version and tap 7 times on the kernel line to activate the developer mode.
- Go back to Settings → Additional → Developer Settings and find Bluetooth Codecs. Select SBC.
- Turn off Dual Audio and Absolute Volume in Bluetooth settings.

3.Problems with Huawei Health app: synchronization errors
The official Huawei Health app (or Honor Health for some regions) often conflicts with MIUI due to aggressive optimization.Even if you manually allowed background activity, the system can reset settings after an update or reboot.
Critical error: In MIUI 13.0.1–13.0.4, the Huawei Health app cannot properly handle notifications due to a bug in the NotificationListenerService service, which causes the clock to turn off when you receive an SMS or call.
How to fix it:
- 📲 Turn off battery optimization for Huawei Health: Settings → Annexes → Application management → Huawei Health → Battery → Without restrictions, settings → Battery and productivity → Choice of applications → Huawei Health → No restrictions.
Reset the app cache
Settings → Applications → Huawei Health → Storage → Clean the cacheInstall a modified version
How to install a patched version of Huawei Health?
If you do this, try using an alternative app, Notify & Fitness for Huawei (available on Google Play), which bypasses some of the limitations of MIUI, but may not support all of the Honor 5’s features.
4. Hardware malfunctions: when Bluetooth module is to blame
If software methods fail, the problem may be physical damage to the Bluetooth module on the phone or watch, especially for the Redmi Note 8/9/10, where the Bluetooth antenna is located next to the camera and often suffers from falls.
Signs of hardware malfunction:
- 📉 The clock is off less than 1 meter from the phone.
- 🔌 Bluetooth on Redmi works unstable with any devices (headphones, speakers).
- 🔥 The phone overheats in the upper left corner (where the Bluetooth module is located).
- 📶 Turn off Wi-Fi: on some versions MIUI Simultaneous operation of Wi-Fi and Bluetooth causes conflicts.
- 🔌 Use third-party launchers: for example, Nova Launcher can bypass some restrictions. MIUI background-process.
