A: If you are not receiving message notifications, check these points:

App Notification Settings: Verify that “Message notification” is turned on in the Mi Fitness App. Check if “Mirror notification” is enabled or if the specific app’s notification switch is turned on. If these are off, the band cannot receive messages.
App Permissions: Ensure the Mi Fitness App has sufficient permissions, including notification access and background running permissions, to allow the app to push messages to the band.
Band Settings: Check the following settings on your band:
1. Settings -> Notifications -> Reminder when wearing and not wearing: Verify if the reminder setting is configured as desired.

Viewing Heart Rate Data in the App:

Mi Fitness App: Go to Health -> Heart Rate. Here you can view your all-day heart rate curve, as well as maximum, minimum, resting heart rate, and any instances of excessively high or low heart rate.

Note: Inaccurate heart rate readings can be caused by non-standard wearing methods. Ensure the band is snug against your wrist to prevent light leakage. Arm movements or band shifting can also affect accuracy. Wearing the band too tightly, raising your arm excessively, or clenching your fist can restrict blood circulation and impact heart rate signal quality.

2. Q: What are the heart rate zones on Xiaomi Smart Band 8?
A: Heart rate zones represent ranges or levels of your heart rate relative to your maximum heart rate. They indicate the workload on your heart and are commonly used to gauge exercise intensity.

Troubleshooting Common Issues

1. Q: What should I do if my Xiaomi Smart Band 8 won’t turn on?
A: If your Xiaomi Smart Band 8 is not powering on, try these troubleshooting steps:

Initial Activation: For first-time use, connect the charging cable to activate the device.
Low Battery: The device battery might be depleted. Charge it for at least 5 minutes using the standard charging cable before attempting to power it on.
Standard Charger: Ensure you are using the standard charging cable provided with the device.
USB Adapter: If using a mobile power bank to charge, try switching to a standard USB adapter connected to a wall outlet.
Clean Charging Contacts: Inspect the charging contacts on the back of the band and the charging base/cable. Clean them with a paper towel or a cotton swab dipped in alcohol (if rust is present) to ensure good contact.
Remove Protective Films: Check if any protective films are still attached to the charging base or the back of the band and remove them.
Check Connection: Ensure the charging cable and device are properly connected, trying unplugging and replugging several times. Apply slight pressure or wiggle the connection to ensure complete contact.

After-Sales Support: If the device remains unresponsive after prolonged charging, contact customer service for after-sales testing and support.

2. Q: Why does the band have a black screen and become unresponsive when I tap it?
A: If your Xiaomi Smart Band 8 is not paired, it will automatically shut down after 30 minutes to conserve battery. Recharge and power on the band before use.

3. Q: Why does the band shut down due to high temperature?
A: Xiaomi Smart Band 8 incorporates a high-temperature shutdown protection mechanism for user safety. If the device temperature becomes excessively high, it will trigger a shutdown to prevent overheating. After a high-temperature shutdown, charging the device will allow it to cool down and restart.

4. Q: Why don’t the buttons on the Xiaomi Smart Band 8 wristband rebound properly after assembly?
A: The Xiaomi Smart Band 8 wristband features a quick-release mechanism. The quick-release button is intentionally designed as a movable part. To ensure the wristband remains secure after assembly and prevent shaking, the wristband is designed to fit tightly. If the button doesn’t fully rebound after assembly, firmly and quickly press the wristband into place during assembly. This ensures proper engagement and button spring-back.

5. Q: Can the Xiaomi Smart Band 8 wristband shake slightly after assembly?
A: Yes, a slight shake in the Xiaomi Smart Band 8 wristband after assembly is normal. The quick-release button is a movable component with a small gap designed for smooth operation and quick-release functionality. This slight movement is not a malfunction and is intended to ensure proper quick-release mechanism operation.

6. Q: Will wearing Xiaomi Smart Band 8 cause allergies?
A: The standard Xiaomi Smart Band 8 wristband is made of professional, healthy, and antibacterial material that meets the limited requirements of national standard GB/T 26572. However, due to individual sensitivities, a small number of people may experience reactions to specific materials, leading to suspected allergic symptoms.

Possible causes of suspected allergic symptoms:

Tight Fit and Lack of Breathability: Wearing the band too tightly and without allowing skin to breathe can cause redness and itching due to friction.
Residue Buildup: Not cleaning the band after showering or prolonged wear can lead to residue accumulation, potentially causing irritation.

If you experience severe allergic reactions, discontinue wearing the band and consult a doctor.

For mild redness and itching, follow these guidelines:

Exercise Wear: During exercise, wear the band neither too loosely nor too tightly to prevent it from sliding on your wrist.
Daily Wear: For daily use, slightly loosen the wristband to allow skin to breathe and maintain comfort.
Breaks: After prolonged continuous wear, remove the band and let your wrist rest for about half an hour.
Cleaning: After exercise, wash and dry your arm and the wristband to remove sweat and residue before wearing it again.

7. Q: Why does the black wristband of Xiaomi Smart Band 8 attract dust easily?
A: Xiaomi Smart Band 8 wristbands, like many wearables, will inevitably come into contact with dust during use. The apparent ease of attracting dust is not related to color. Black wristbands may simply show dust more prominently due to higher visual contrast, making dust more noticeable.

8. Q: Why is it difficult to fasten the Xiaomi Smart Band 8 wristband buckle?
A: The Xiaomi Smart Band 8 wristband buckle and strap holes are designed with an interference fit to ensure the strap remains securely fastened and doesn’t loosen easily.

Buckling Method:

Place the band on your wrist and pass the long strap through the tail bezel of the short strap.
Adjust the strap tightness to your comfort.
Align the mushroom head of the buckle with the desired strap hole.
Place your index finger under the long strap and firmly press the buckle with your thumb and index finger to close it securely.

9. Q: Why does the Xiaomi Smart Band 8 wristband buckle come off easily?
A: When wearing the band, avoid scratching the end of the short strap (buckle end) with hard objects to prevent accidental detachment. The strap has an arc-shaped structure designed to conform to the wrist, preventing automatic fall-off even if the buckle loosens accidentally. Simply retighten the buckle. If the buckle hole becomes worn or deformed from long-term use, causing frequent detachment, the strap should be replaced.

10. Q: Xiaomi Smart Band 8 displays “After-sales mode, please contact after-sales maintenance.” What should I do?
A: We sincerely apologize for any inconvenience. If you encounter this “After-sales mode” message, please contact customer service or visit your nearest service outlet for assistance. This issue is caused by a very rare software bug that may occur during software operation, leading the device to enter a protection mode. The hardware itself is typically normal. This issue has been resolved in newer software versions. Upgrading to the latest firmware will prevent this problem from recurring and will not affect future use or updates.

11. Q: What should I do if Xiaomi Smart Band 8 is stuck on the watch face interface and touch control is unresponsive?
A: Follow these steps if your Xiaomi Smart Band 8 touch controls are not working:

Unpaired Band: If the band is unpaired, leave it for 30 minutes to allow it to automatically power off. Then, use the charger to reactivate the band.
Paired Band: If the band is paired, unpair it from the Mi Fitness App. Wait for the band to automatically restart, and then pair it again with the app.

12. Q: Can Xiaomi Smart Band 8 be worn with metal jewelry or mineral jewelry? Will it damage the surface?
A: The Xiaomi Smart Band 8 shell is made of plastic with a high-gloss metallic paint finish. While it has a metallic appearance, it is essentially a plastic product. Wearing it with harder metal jewelry (metal bands, bracelets) or mineral jewelry (jade, crystal) can scratch, bruise, abrade, or cause paint peeling on the band’s surface. Therefore, it is not recommended to wear the band alongside metal or mineral jewelry. Wear them separately on different wrists to prevent damage.

13. Q: What should I do if the wristband of Xiaomi Smart Band 8 shakes or feels loose? Is there a way to fix it?
A: During daily use, avoid strong pulling, twisting, or tugging on the wristband. These actions can deform or open the positioning post on the wristband head, leading to shaking and gaps after wristband installation, affecting the user experience.

If this has occurred, try these solutions:

Pinch and Restore: Pinch the head of the wristband firmly to try and restore the open positioning column to its original shape. This may reduce shaking and gaps to some extent.
Purchase Replacement Wristbands: Xiaomi Smart Band 8 offers a variety of retail wristbands. Consider purchasing a replacement wristband if needed.

Note: If the wristband shaking is confirmed as a product defect, normal after-sales service, including wristband replacement, is available.

14. Q: After using the mobile phone mute application to silence my phone, the phone only vibrates but has no ringtone. However, with Xiaomi Mi Band 5/6/7, muting the phone silences both ringtone and vibration. Why is Xiaomi Smart Band 8 different?
A: This difference is intentional. Xiaomi Mi Band 5, 6, and 7 activated the phone’s “Do Not Disturb” mode when the mute application was used. “Do Not Disturb” mode silenced both ringtone and vibration (except for “Allow Disturbance” exceptions). Xiaomi Smart Band 8 decouples these functions (Silent and Do Not Disturb). Turning off the ringtone on Xiaomi Smart Band 8 only mutes the phone’s ringtone, while vibration settings remain as originally configured. It no longer automatically enters “Do Not Disturb” mode.

If you wish to quickly enable “Do Not Disturb” mode from your wristband (silencing phone ringtone, vibration, and message prompts), you can directly turn on the “Do Not Disturb” switch and “Do Not Disturb sync phone” switch within the band’s settings. This provides more granular control over phone silencing and notification behavior.
