You bought the Honor Band 5, one of the most popular fitness bracelets on the market, but you faced an annoying problem: does the device constantly lose touch with a Xiaomi smartphone? Don't rush to blame the manufacturer or run to the service center. In 90% of cases, the problem is solved software, and often the fault is incompatible settings, not hardware malfunctions.
This article will help you understand why the Honor Band 5 switches off from Xiaomi phones (including Redmi Note models) 10/11/12, POCO X3/X4, Mi 11/12 And others, even if it used to work consistently, and we looked at user feedback, technical forums and official recommendations. Huawei/Honor, We can do this to put together a full list of causes, from the trivial to the little ones, and most importantly, we can make step-by-step solutions that work in the future. 2026 year.
And we warn you right away, if you've only tried rebooting your wristband and your phone, you've missed 80 percent of the effective methods, and let's start with the obvious, and we'll get to the hidden settings that are not even written about in the instructions.
Bluetooth Version Conflict: Why Honor Band 5 "can't see" Xiaomi
The most common reason for spontaneous shutdowns is the incompatibility of Bluetooth protocols between the wristband and smartphone. Honor Band 5 supports Bluetooth 4.2, while modern Xiaomi (especially on Snapdragon 8 Gen 1/2) often work with Bluetooth 5.0+. Theoretically, they should be compatible, but in practice there are software conflicts.
How it manifests itself:
- 🔄 The bracelet is connected, but after 5-30 minutes the connection is cut off.
- 📱 In the settings Xiaomi Bluetooth shows “Connected without the Internet”, although previously it was “Connected to media".
- ⚠️ Notifications are delayed or not coming at all.
- 🔋 Bracelet battery discharge is accelerated by 2-3 times.
The solution lies in manually setting up Bluetooth mode on your smartphone, because Xiaomi defaults to power-saving Bluetooth mode, which breaks the connection with low-power devices (and a fitness bracelet is one of them).
Turn off the “Adaptive Bluetooth” mode in the settings
Enable "Constant Connection" for Honor Band 5
Update the Bluetooth module firmware (if available)
Restart both devices after the changes-->
Step instructions:
- Open Settings → Connections and Sharing → Bluetooth.
- Find Honor Band 5 in the list of conjugate devices and tap the gear (⚙️) near.
- Activate the option "Allow data exchange in the background" (on some MIUI firmware it is called "Constant connection").
- Return to the basic Bluetooth settings and turn off “Adaptive Bluetooth” (or “Bluetooth Energy Saving”).
- Reboot your smartphone and bracelet.
⚠️ Attention: On Xiaomi phones with firmware MIUI 13/14 The "Constant Connection" option may not be available, in which case, try rolling back the Huawei Health app to the previous version. 12.0.1.300 — It has fewer Bluetooth bugs.
2.Problems with the Huawei Health app: bugs and cache
Huawei Health (formerly Huawei Wear) is the second most popular source of problems, not only because of the program’s bugs, but also because of how it interacts with MIUI. For example, Xiaomi’s background optimization often kills Huawei Health’s processes, causing the bracelet to lose touch.
Signs of a problem:
- 📵 The bracelet turns off when the phone screen is turned off.
- 🔄 Huawei Health app doesn’t update real-time data (steps, pulse).
- ⚠️ The notifications read, "Connection lost. Retry again".
- 📲 Forced shutdown of Huawei Health app leads to bracelet instantly shutdown.
What to do:
- Clear the cache and app data: Go to Settings → Apps → App Management → Huawei Health. Tap Storage → Clear Cache and Clear Data. After that, you will have to re-enter your account and sync the bracelet!
- Turn off battery optimization for Huawei Health: Go to Settings → Apps → Application Management → Huawei Health → Battery. Select “No Limits” (or “No Optimization”).
Update or roll back the app version:
The current version of Huawei Health (at 2026) is 13.0.x.xxx. However, many users note that version 12.0.1.300 is more stable.
💡
If the bracelet doesn’t connect after cleaning the cache, try removing it from the list of devices in Huawei Health, then re-add it through Add Device → Bracelet → Honor Band 5.
3. MIUI Energy Saving: Why Xiaomi is Killing the Connection
MIUI is known for aggressive battery optimization, which often interferes with background processes. If your Honor Band 5 shuts down after 10 to 20 minutes of inactivity, it's this mechanism that's to blame, especially for phones with ultra-energy saving or adaptive battery mode.
How to check:
- 🔋 Go to Settings. → Battery and productivity → Battery mode.
- 📊 See if the energy saving or ultra-energy saving mode is included".
- ⚡ If yes, switch to High Performance (at least temporarily for the test).
Solution: Turn off optimization for Huawei Health and Bluetooth:
- Go to Settings → Applications → Application Management → Huawei Health → Battery.
- Select "No Limits."
- Return to Settings → Battery and Performance → Battery Settings → Battery Optimization
- Find Huawei Health in the list and turn off optimization (slider in the “Off” position).
- Do the same for Bluetooth System Settings (if listed).

Ultra-energy conservation
I don't know.-->
⚠️ Attention: On some firmware MIUI 14 No Limits option may not be available, in which case, try adding Huawei Health to Secure Apps (path: Settings) → Battery → Secure applications).
4. Conflict with other Bluetooth devices
If your Xiaomi has other Bluetooth devices (headphones, speakers, second bracelets, smartwatches) connected to it, they can compete for a communication channel, especially on budget models (Redmi 9/10, POCO M3/M4), where the Bluetooth module is weaker.
Symptoms:
- 🎧 The bracelet turns off when you listen to music over Bluetooth.
- 🔊 Communication is cut off when connected to a car tape recorder.
- 📱 In Bluetooth settings, you can see that the bracelet is connected, then disappears from the list.
How to fix it:
- Limit the number of connected devices: Leave only the Honor Band 5 and one audio device (if necessary).
- Enable the "Priority for Accessories" mode: Open Settings → Connections and sharing → Bluetooth, hit three points (⋮) in the upper right corner, select "Priority for Accessories" (or "Wearable Device Mode").
Dual Bluetooth
| The device | Max. stable Bluetooth connections | Recommendation |
|---|---|---|
| Xiaomi Redmi Note 10/11 | 3–4 | Keep no more than 2 active devices |
| POCO X3/X4 Pro | 4–5 | Turn off Dual Audio in the settings |
| Xiaomi 11T/12 Pro | 5+ | Turn on "Priority for Accessories" |
| Redmi 9/9A | 2–3 | Only connect the bracelet or headphones. |
5. Problems with the firmware of the bracelet or phone
If the Honor Band 5 started to shut down after updating the MIUI or firmware bracelet, the fault is a software conflict. for example, MIUI 13.0.4-13.0.6 was a bug with Bluetooth LE (Low Energy), which caused wearable devices to lose communication. and in the firmware Honor Band 5 version 1.1.0.56 there was a synchronization error with Xiaomi.
How to check the versions:
- 📱 On the phone: Settings → The phone. → Version. MIUI.
- ⌚ On the bracelet: Open Huawei Health → "My devices" → "Firmware update".
Decisions:
- Update the bracelet firmware: Open Huawei Health → My Devices → Firmware Update. If a new version is available, install it (the bracelet must be charged at 50%+).
- Roll back the version. MIUI (If the problem has occurred after the update: This is an extreme measure, but if you are sure the update is to blame MIUI, You can roll back through Fastboot or Recovery. 4PDA for your model.
- Reset your bracelet settings: At Huawei Health, go to My Devices → Honor Band 5 → Reset. Once reset, the bracelet will return to factory settings and have to reconfigure it!
Which versions of Honor Band 5 firmware work with Xiaomi?
Hardware malfunctions: when the "iron" is to blame
If you've tried all the software solutions, but the Honor Band 5 still shuts down, the problem could be the hardware.
- 🔋 Battery discharge bracelet (even if it shows 20-30%, the real charge may be lower).
- 📶 Poor contact in the charging connector (bracelet does not charge fully).
- 🔌 Faulty Bluetooth module in phone or bracelet.
- 💧 Moisture intake (even if the bracelet has protection) 5ATM, contact could be oxidized).
How to diagnose:
- Check the bracelet's charge: Connect the bracelet to charge for 1-2 hours (even if it shows 50%+).
- Test the bracelet with another phone: Connect the Honor Band 5 to a smartphone of another brand (Samsung, iPhone). If there are no outages, there is a problem in Xiaomi (possibly a faulty Bluetooth module).
- Check the charging connector: When you connect the charging, the bracelet should vibrate and show a charging indicator. If not, clean the contacts with alcohol or a soft brush.
⚠️ Attention: If the bracelet is turned off during physical activity (running, training), the problem may be poor contact inside the body. This is typical for bracelets that often fell or were hit.
7. Alternative solutions: if nothing helps
If all of the above methods do not work, try non-standard approaches:
- 🔄 Use Notify & Fitness: This is a third-party wearable device management software that often runs more stable than Huawei Health.
- 📵 Turn off Wi-Fi when synchronized: Sometimes Wi-Fi and Bluetooth conflict at the core level MIUI. Try to turn off Wi-Fi while connecting the bracelet.
- 🔧 Turn on Developer Mode and change Bluetooth settings: 1. Activate Developer Mode (7 taps for "Build Number" in "About Phone"). 2. Go to "Settings" → Additionally. → For developers." 3. Find "Bluetooth Settings" and turn on "AVRCP 1.6" (if any). 4. Turn off "Bluetooth" A2DP Hardware Offload".
