After the band vibrates and displays the prompt, tap Confirm to complete the binding. Once the binding is successful, the Mi Fitness App will display that the device has been added successfully, and the band will display the band display home screen.
Q14: Does the phone’s Bluetooth need to be kept on when using the Xiaomi Smart Band 11 Active?
A: When using the Xiaomi Smart Band 11 Active:
1. Steps counting, sleep & heart rate monitoring, stress/blood oxygen detection, and cycles can record data independently without a mobile phone. You need to connect to the mobile phone regularly to synchronize sports and health data. It is recommended to connect the mobile phone to record the track during exercise.
2. Functions such as stopwatch, alarm, etc. do not require Bluetooth to be turned on all the time.
Note:
1. To better use the band, it is recommended to keep the Mi Fitness App running in the background. To avoid memory cleaning in the Android system and some security software cleaning processes or interception, please set it according to the requirements in the Mi Fitness App >> [Device] >> [System] >> [Band connection protection] >> [Lock the app in background].
2. iPhones cannot add background protection to applications. If the Mi Fitness App enters the background and is cleared, the system Bluetooth connection will not be disconnected. Message notifications can be used normally. Other data synchronization Apps on the band (weather, fitness and health data synchronization, schedule, etc.) need to reopen the Mi Fitness App on the phone to use.
3. When iPhones turn on power-saving mode, the system Bluetooth connection stability will deteriorate, and disconnection can occur.
Q15: Why does the Xiaomi Smart Band 11 Active not synchronize data when it is disconnected from the iPhone for a long time?
A: If the Mi Fitness App is running too much in the background, it will be cleared, and the Xiaomi Smart Band 11 Active will be disconnected from the Mi Fitness App, resulting in data synchronization failure. You need to enter the Mi Fitness App to automatically reconnect and synchronize data. When the Mi Fitness App is cleared in the background, reopening the Mi Fitness App will automatically reconnect to the device, and you can use it normally.
Reasons for clearing the background:
The reason why background applications are cleared is that the running memory (RAM) has been used up by the App. In order to free up enough running conditions for other newly opened applications, the system must clear some background running applications to free up RAM. Due to differences in models and iOS system software versions, the frequency of background clearing will vary. Taking the iPhone 12 as an example, the memory is 4 GB. When 4 applications are opened in iOS 16.3.1, the background clearing phenomenon will occur. After upgrading the version to iOS 16.4, there is no background clearing phenomenon when 5-6 applications are opened (it is related to the specific App, such as the Camera occupying a relatively large amount of memory).
During normal use, pay attention to the following two points to reduce the frequency of background clearing:
1. Ensure that the phone has sufficient power, avoid overheating, and turn off battery saver mode. Otherwise, the CPU will be actively downgraded, and the frequency of background clearing will increase significantly.
2. Open the iPhone's [Settings] >> [General] >> [Background App Refresh] in sequence and enable this function.
Determine whether the application is cleared by the system:
1. If the Mi Fitness App is cleared in the background, re-entering the Mi Fitness App will display the following two operation interfaces in order: first display the Mi Fitness App startup interface, then display the Mi Fitness App home interface.
2. If the Mi Fitness App is not cleared in the background, the interface where you operated before exiting the Mi Fitness App will be retained when you enter it.
If the band is physically separated from the phone for a long time and the phone is put back together, it prompts that the Bluetooth is disconnected. Please refer to the following troubleshooting steps:
1. Check whether the Mi Fitness App has been cleared from the phone’s background. If it has been cleared, reopen the Mi Fitness App.
2. Check whether the phone’s Bluetooth has been turned off. If so, turn Bluetooth back on.
3. Check whether the band is too far away from the phone, which can cause the connection to be lost. Make sure Bluetooth is enabled on the phone, open the Mi Fitness App, and tap to connect manually.
Q16: Why can't the Xiaomi Smart Band 11 Active reconnect to the current phone after the same Xiaomi account is logged in on multiple phones, and why does the Mi Fitness App not show the device?
A: Please refer to the following reasons:
1. The current phone cannot reconnect. The old phone has unbound the Xiaomi Smart Band 11 Active, and the new phone has not synchronized the account, so it cannot reconnect to this device.
2. Confirm which interface the band screen is displaying. If it is on the QR code interface or language selection interface, unbind the device in the Mi Fitness App on your phone, then scan and pair again.
3. Check whether the Bluetooth icon on the band is always on. If so, use [Find phone] to confirm whether it is connected to the current phone. If not, unbind the device on the Mi Fitness App and rebind the band with the current phone (for the unbinding method, refer to the above Android & iOS unbinding methods).
4. If there is no band on the device management interface of the old phone's Mi Fitness App, it means that the old phone has unbound the device. After logging in to the same account and synchronizing with the new phone, the band will not be displayed. If the band is on the QR code interface or language selection interface, re-scan and pair.
5. Connect the band to two phones with the same Xiaomi Account on the Mi Fitness App. After the band is restored to factory settings, use the new phone to re-pair it and turn off the Bluetooth of the old phone. If the new phone cannot connect again, it could be because the new phone has not automatically pulled the new login and pairing information.
Suggestions:
1. Please try to avoid logging into multiple mobile phones with one account.
2. If you are unable to reconnect, please turn off the Bluetooth function of other devices that have logged in to this account and try again.
3. Please keep the network in good condition, close the Mi Fitness App, and reopen it to trigger the cloud to resend login and pairing information to ensure that the band can reconnect.
Q17: Why does the Xiaomi Smart Band 11 Active show disconnection when connected to the Android device?
A: The Mi Fitness App is cleared in the background, so please confirm whether all background running permissions of the Mi Fitness App are enabled.
The setting path is as follows:
After the Xiaomi Smart Band 11 Active and the Mi Fitness App are connected, go to the Mi Fitness App interface >> [Device] >> [System] >> [Band connection protection] >> enable the settings by following the guide. In the [Setting methods], check whether [Turn off Battery saver], [Select "No restrictions" in Background settings], [Allow app autostart], and [Lock the app in background] are all enabled.
Recovery methods:
1. Check whether the Mi Fitness App is already updated to the latest version. If not, update the app to the latest version.
2. Check whether all permissions for the Mi Fitness App have been granted, especially the Bluetooth connection permission.
3. Check whether the phone’s Bluetooth has been turned off. If so, turn Bluetooth back on.
4. Check whether the band is too far away from the phone, which can cause the connection to be lost. Make sure the phone’s Bluetooth is enabled, open the Mi Fitness App, and tap to connect manually.
Q18: Why can’t the Xiaomi Smart Band 11 Active be searched when paired with a new phone after it has been unilaterally restored to factory settings?
A: Please refer to the following troubleshooting steps:
1. When an iPhone is connected to the Xiaomi Smart Band 11 Active and the band is unilaterally restored to factory settings, the iPhone's system Bluetooth will try to reconnect to the band, and the new phone cannot search the band. (The iPhone and the device will always be connected. During the connection period, the new phone cannot be searched. During the disconnection period, the new phone is in scanning mode and can search the band.) You need to enter the iPhone's system Bluetooth settings, find the corresponding connected device, and tap [Forget This Device]. At this time, use the new phone to search and pair the band.
2. When the Android phone is connected to the band and the band is unilaterally restored to factory settings, the Mi Fitness App will reconnect to the device and prompt you to [Remove] or [Add]. At this time, the new phone cannot search for the band. Tap [Remove] and then search and connect with the new phone.
Q19: What to do if the Xiaomi Smart Band 11 Active cannot be searched when rebinding after unbinding?
A: Manually toggle the phone's Bluetooth setting off and on, and restart both the Xiaomi Smart Band 11 Active and the mobile phone.
Q20: What to do if the Mi Fitness App indicates a pairing failure while trying to pair the Xiaomi Smart Band 11 Active with an iPhone?
A: If the following phenomenon occurs, please open the Bluetooth settings of the mobile phone system to check whether the Xiaomi Smart Band 11 Active is connected.
If the current device is already connected, tap the small circle behind [Connected], and then tap [Forget This Device].
Note:
If the problem is still not fixed after following these steps, it is recommended to restart the band, restart the phone's Bluetooth, restart the phone, and try again.

At this time, if you receive a message with the deleted icon again, you need to request the icon again. Therefore, if there are many Apps on the phone and messages are pushed regularly, you will observe that when the band message is displayed, the default icon is displayed on the reminder interface, and then the corresponding application icon is displayed in the notification center. You can choose to turn off uncommon messages.

Q3: Why does the black strap of the Xiaomi Smart Band 11 Active easily get dusty?
A: The Xiaomi Smart Band 11 Active will inevitably come into contact with dust when worn. In fact, whether it is easy to absorb dust has nothing to do with color. It’s just that the contrast of the black strap is stronger, and it is easier to see visually after absorbing foreign matter.
Q4: Why is the Xiaomi Smart Band 11 Active strap pin difficult to fasten?
A: To ensure that the Xiaomi Smart Band 11 Active strap pin remains securely fastened and is not easily detached, the strap pin and strap hole are designed with an interference fit.
To install the strap, please place the band body on the wrist in the desired wearing position, then pass the long strap through the loop at the end of the short strap. Adjust the strap to the appropriate tightness. When fastening the strap pin, align the mushroom-shaped head of the pin with the strap hole. Place the index finger underneath the long strap, then press the strap pin firmly into place using the thumb and index finger. The strap pin is properly fastened once it is securely engaged.
Q5: Why does the Xiaomi Smart Band 11 Active strap pin easily come undone?
A: When wearing the Xiaomi Smart Band 11 Active, avoid scraping the end of the short strap (the strap-pin side) against hard objects, as accidental contact may cause the strap pin to come undone. The strap is designed with a curved structure that follows the shape of the wrist. If the strap pin accidentally loosens, it will not automatically fall off without external force, so simply fasten the strap pin again promptly.
If long-term use causes the corresponding strap hole to become worn or deformed, making the strap pin more likely to come undone, replace the strap in a timely manner.

Q7: What to do if the Xiaomi Smart Band 11 Active cannot be charged or cannot be fully charged?
A: If the Xiaomi Smart Band 11 Active cannot be charged or cannot be fully charged, please follow the steps below to troubleshoot:
1. Some power banks on the market have built-in power-saving sleep mechanisms. When the band is almost fully charged, the required charging current becomes very low, and the power bank will determine that no device is currently drawing power and automatically disconnect the 5 V power output to enter sleep mode. Therefore, after the power is disconnected during charging, the band cannot continue charging to reach 100%. This phenomenon is not a fault with the band itself. It is recommended to use a standard USB charger with a 5 V output voltage and an output current of more than 250 mA, together with the supplied dedicated charging cable, for charging.
2. Check whether there is any dirt on the metal contacts of the band body and the metal contacts of the charging cable. Try wiping them with an alcohol pad, tissue, or similar material to ensure that there is no poor contact between the band body and the charging cable.
3. Check whether the charging adapter is functioning normally. Try using another standard adapter with the band charging cable to charge the band.
4. Check whether the charging cable is functioning normally. If a spare charging cable for the same model of band is available, try replacing the charging cable.
5. Try charging the band in an environment with a temperature of 10 °C or above.
6. The Xiaomi Smart Band 11 Active takes approximately 1 hour and 50 minutes to charge. If the band cannot be fully charged, check the charging duration to determine whether the charging time was too short to complete the charging process.
7. When the charging level reaches 100%, do not disconnect the charging cable immediately. It is recommended to continue charging the band on the charging dock for another 6-7 minutes.
8. If there is still no response after charging for an extended period, contact the after-sales service for inspection.
Note:
Please check whether the ambient temperature around the band is too low or too high while charging. The system will prevent the band from charging when the ambient temperature is too high or too low. Charging will automatically resume once the temperature returns to a normal range.
Q8: Can the Xiaomi Smart Band 11 Active be charged by a power bank?
A: When charging the Xiaomi Smart Band 11 Active with a power bank, the band may not be able to charge fully. It is not recommended to use a power bank to charge the band.
Most power banks on the market have an automatic charging shutoff feature when the battery is fully charged, and the power bank will automatically disconnect when the discharge current drops below a certain level. The charging current of the band is very low, so the power bank will mistakenly determine that the band is fully charged and disconnect the charging current to the band. As a result, the band will not be fully charged or will be unable to charge.
Therefore, when using a power bank to charge the band, charging may fail to start or cannot reach full capacity.
Q9: What to do if the charging cable falls during charging the Xiaomi Smart Band 11 Active?

Health-Related
Q1: Does the Xiaomi Smart Band 11 Active support sleep monitoring? What is the monitoring range?
A: The Xiaomi Smart Band 11 Active supports sleep monitoring and can record both long sleep and sporadic naps, with monitoring available throughout the entire 24-hour period. After the band is worn normally during sleep, the band can automatically identify the sleep state through its built-in sensors.
Please refer to the details below:
1. A sleep duration of 3 hours or more is recorded as long sleep, while a duration of less than 3 hours is recorded as a sporadic nap. Sleep lasting less than 20 minutes may not be recorded.
2. The band supports sleep advanced monitoring throughout the day. After this feature is enabled, it can track the distribution of rapid eye movement (REM) sleep. However, this will significantly reduce the device's battery life. In addition, after sleep advanced monitoring is enabled, the large amount of data generated by the monitoring feature means that it is recommended to connect to the Mi Fitness App every day to synchronize the data and view complete sleep records.
Sleep record viewing method:
The main sleep record for the current day can be viewed on the band. After the band is connected to the phone and the data is synchronized, tap [Sleep] in the Mi Fitness App to view historical sleep data, including daily, weekly, monthly, and yearly data. Sleep distribution includes total sleep duration, awake duration, light sleep duration, and deep sleep duration. The sleep state at each point during the daily sleep period can also be viewed. Rapid eye movement (REM) sleep can only be recorded after the advanced monitoring feature is enabled.
Note:
When the band is in a relatively quiet state, and the movement amplitude is similar to that during sleep, the sensor may identify the state as sleep, which can result in an inaccurate sleep onset time. For example, sleep can be incorrectly recorded while watching TV, lying in bed and using a phone, or reading a book. This can be because the movement amplitude and frequency are relatively small and similar to those during sleep.
Q2: Does the Xiaomi Smart Band 11 Active support Breathing score (Beta)?
A: The Xiaomi Smart Band 11 Active supports Breathing score (Beta).
The principle of Breathing score (Beta) is as follows:
Snoring or other conditions during sleep (such as obstructive sleep apnea) can cause a significant decrease in blood oxygen saturation. The device determines whether breathing difficulties occur during sleep by monitoring changes in blood oxygen saturation and sleep quality during sleep. Based on the number of times breathing difficulties occur, a corresponding sleep breathing quality score will be provided in the Mi Fitness App. Poor sleep breathing quality may cause fatigue and drowsiness during the day.
After Breathing score (Beta) is enabled, the large amount of data generated by the monitoring feature means that it is recommended to connect to the Mi Fitness App every day to synchronize the data and view complete sleep records. Enabling Breathing score (Beta) will significantly reduce the band’s battery life. Please choose whether to enable this feature according to your needs.
You can go to the Mi Fitness App home interface >> [Sleep] >> tap the three dots icon in the upper right corner >> [Settings] >> turn on/off [Breathing score (Beta)].
You can also go to the band's [Sleep] App >> [Settings] >> turn on/off [Breathing score].
Q3: Why is there no sleep data when swiping to the sleep widget of the Xiaomi Smart Band 11 Active after waking up?
A: When you use the Sleep App during sleep, the Xiaomi Smart Band 11 Active will determine that you have already woken up and are viewing the sleep data on the band, and it will also record your sleep end time.
Swiping left or right on the widget may be caused by accidental touches after falling asleep. To prevent an accidental touch from directly ending the sleep record, when the algorithm has not yet fully identified that you have woken up, swiping to the sleep widget will not record the end of sleep or refresh the sleep data.
Therefore, the data displayed on the sleep widget will not match expectations immediately after waking up.
Q4: Why is there no monitoring record or score in the Mi Fitness App after turning on the sleep breathing score of the Xiaomi Smart Band 11 Active?
A: Please check the following aspects:
1. Check whether sleep breathing score is enabled in the Mi Fitness App. Go to the Mi Fitness App >> [Device] >> [Fitness and health] >> [Sleep] >> turn on [Breathing score (Beta)].
2. If the sleep duration is too short, the effective monitoring duration can be insufficient, and the sleep breathing score or monitoring data will not be displayed. Generally, the nighttime sleep duration should be more than 3 hours.
3. An improper wearing position can prevent the sleep breathing score from being monitored properly. It is recommended to wear the band snugly without being too loose, with the device positioned approximately one finger-width away from the wrist bone.
4. If none of the above applies, check whether the Mi Fitness App and the band firmware versions are up to date. It is recommended to restart the band or unbind and rebind the band with the Mi Fitness App, then try again.
Q5: How long does it take for the Xiaomi Smart Band 11 Active to complete a single blood oxygen saturation measurement?

Wearing conditions, skin characteristics, environmental conditions, and other factors can cause the measurement to time out.
It is recommended to adjust the band to ensure that the back of the band is in close contact with the wrist.
Q6: What changes will occur in the sensor indicator at the bottom of the Xiaomi Smart Band 11 Active when measuring blood oxygen saturation?
A: The red light and infrared light (invisible to the naked eye) of the Xiaomi Smart Band 11 Active will turn on. If the green light is flashing, it indicates that the heart rate is being measured.
Q7: Why is there a red indicator on the Xiaomi Smart Band 11 Active flashing when it is not worn at night?
A: Please check the following aspects:
1. When the Xiaomi Smart Band 11 Active has all-day blood oxygen tracking enabled, it will automatically measure blood oxygen after falling asleep, and the red light on the band will flash. If the band is not being worn and the red light is found to be flashing, the wearing detection function may have performed an incorrect measurement.
2. The Xiaomi Smart Band 11 Active uses a high-precision PPG heart rate sensor with infrared, green light, and red light. Compared with traditional wearing detection, the monitoring accuracy has been greatly improved. However, when the environment in which the band is placed is relatively similar to a wrist, incorrect measurements will still occur.
3. When the band is not being worn and is placed somewhere, make sure that no objects are blocking the area behind the heart rate light. Common situations that can cause incorrect measurements include placing the band inside a bag or on a bed or table.
4. If the band is not worn during sleep, it is recommended to turn off the sleep advanced monitoring function, which can significantly save battery power. In addition, after sleep advanced monitoring is enabled, the large amount of data generated by the monitoring feature means that it is recommended to connect to the Mi Fitness App every day to synchronize the data and view complete sleep records.
Q8: Will there be an abnormal blood oxygen alert on the Xiaomi Smart Band 11 Active when there is a risk?
A: The Xiaomi Smart Band 11 Active can set low blood oxygen alerts at 80%, 85%, or 90%. The measurement results are for reference only and are not intended for medical reference or diagnosis. If you experience any discomfort, please consult a medical institution.
Q9: What to do if the blood oxygen measurement value on the Xiaomi Smart Band 11 Active is very low?
A: If the blood oxygen measurement value on the Xiaomi Smart Band 11 Active is very low, please check the following aspects:
1. The wearing position is incorrect. Since there are fewer blood vessels around the wrist, blood oxygen levels are more difficult to measure. Please wear the band one finger-width away from the wrist bone (the protruding part of the ulna).
2. The band is worn too loosely. Please wear the band slightly tighter, with a slight sense of snugness. Ideally, the band should not move when the wrist is shaken.
3. Stretch the forearm and straighten the elbow joint to avoid blood vessel compression, which can restrict blood flow and make the measurement results unreliable.
4. Place the arm on a stable surface such as a table for measurement, with the band screen facing upward. Avoid movement to prevent unstable signals.
5. It is recommended to adjust the wearing position of the band, ensure that the back of the band is in close contact with the wrist, keep the band still, and then perform the measurement again.
6. Please update the band and the Mi Fitness App to the latest version for an improved experience.
Q10: Does the Xiaomi Smart Band 11 Active support breaks reminders?
A: The Xiaomi Smart Band 11 Active supports breaks reminders. After turning on the breaks reminders switch, when it detects that there is no activity for 50 minutes in each natural hour, the band will vibrate at the 50th minute and remind you to move. If standing and walking are detected within 10 minutes after the reminder, a finished standing reminder will pop up.
Prolonged sitting and insufficient physical activity may lead to various health problems. During daily use of the band, it is recommended to get up and move around once every hour. Maintaining a standing state regularly is a convenient way to reduce prolonged sitting and increase energy expenditure. The breaks reminders can only be enabled in the Mi Fitness App, where the start and end times can be set and Do Not Disturb during lunch breaks can be configured.
You can go to the Mi Fitness App >> [Device] >> [Fitness and health] >> [Breaks reminders] >> turn on/off [Breaks reminders] and set the time period.
Q11: Why does the Xiaomi Smart Band 11 Active pop up breaks reminders even when standing all the time?
A: The purpose of the breaks reminders of the Xiaomi Smart Band 11 Active is to get you moving. The band determines whether the standing activity requirement has been met by detecting data such as wrist movement and step count. Therefore, if you remain standing without moving or only make small movements, the algorithm can not recognize that you have been active, and you will still receive the breaks reminders. It is recommended to walk around or increase your wrist movement. At the same time, we are continuously optimizing the algorithms related to standing detection to gradually improve the usage experience.
Q12: Why does the Xiaomi Smart Band 11 Active suddenly receive the breaks reminders to stand up when just starting to move?
A: The breaks reminders of the Xiaomi Smart Band 11 Active require certain conditions to be met. If you have just started moving and suddenly receive breaks reminders from the band, it is because you are currently active but have not yet reached the threshold for standing activity detection. You can continue moving and ignore the breaks reminders from the band.
If this occurs frequently, you can submit relevant feedback in the Mi Fitness App, and we are continuously optimizing the algorithms related to standing activity detection to gradually improve the usage experience.

Q15: Why is there no heart rate monitoring record on the Xiaomi Smart Band 11 Active?
A: If there is no heart rate monitoring record on the Xiaomi Smart Band 11 Active, please check the following aspects:
1. Check whether the green light is flashing when the back of the band is in contact with the skin. A flashing green light indicates that the band’s heart rate monitoring function is working normally. If the green light is not flashing, check whether heart rate monitoring is enabled.
2. Wear the band correctly. The strap should not be too loose. Adjust the wearing position and then enter the heart rate function on the band again to check.
3. Excessively dry skin and scars on the skin can affect heart rate measurement. Extremely low temperatures in winter can also affect heart rate measurement.
4. If none of the above issues apply, restart the band, wear it on the other arm, and try measuring again.
Q16: Does the Xiaomi Smart Band 11 Active support abnormal heartbeat reminders?
A: The Xiaomi Smart Band 11 Active does not support abnormal heartbeat reminders.
Q17: Why are the stats on the Xiaomi Smart Band 11 Active and the Mi Fitness App inconsistent?
A: When the stats data in the Mi Fitness App is higher than the data on the Xiaomi Smart Band 11 Active, the Mi Fitness App will write the data back to the band. Since writing back the data for the current 30-minute period to the band will cause the band’s own data to be unavailable for display on the band, the strategy has been updated so that the data for the current 30-minute period is not written back to the band. Only the stats data from the rest of the current day, excluding the current 30-minute period, will be written back. Therefore, there will be a half-hour discrepancy when the stats data is integrated and delivered from the Mi Fitness App to the band.

Q10: What to do if the distance error of outdoor workouts is large or there is no track after the workout with the Xiaomi Smart Band 11 Active?
A: Since the Xiaomi Smart Band 11 Active does not have an independent positioning function, all positioning information and track data come from the phone. Therefore, these outdoor workout modes require phone location services to be enabled and the band to remain connected to the phone.
The method to turn on the mobile phone positioning information is as follows:
1. For Android phones, before using the band for outdoor workouts, set the location permission for the Mi Fitness App to [Allow all the time] or [Allow only while using the app], and enable [No restrictions] on the App device interface. Otherwise, the workout track may be unavailable after the workout, and the recorded distance may be inaccurate. If the location permission is set to [Allow only while using the app], or the Mi Fitness App is running in the background, the outdoor workout distance may have a larger deviation, or the workout track may be unavailable after the workout.
2. For iPhones, before using the band for outdoor workouts, set the location permission for the Mi Fitness App to [Always (Default)], and go to the phone's [Settings] >> [App] >> [Mi Fitness] >> [Background App Refresh] and enable [Background App Refresh]. Otherwise, the workout track may be unavailable after the workout, and the recorded distance may be inaccurate.
If the phone's location service is enabled normally and the workout track is displayed in the [History] of the Mi Fitness App, but the recorded distance is still inaccurate, zoom in on the workout track to check whether there are long straight lines in the track. This may occur when surrounding obstructions interfere with the phone's positioning signal, resulting in inaccurate positioning information and consequently inaccurate distance calculation by the band. As shown in the figure, similar scenarios can cause the recorded workout distance to be inaccurate.
Q11: Why does the Xiaomi Smart Band 11 Active not generate workout data after a workout?
A: The Xiaomi Smart Band 11 Active can not save workout records for the following reasons:
1. Make sure the band has sufficient battery power during exercise. If the band powers off or restarts during exercise, no exercise data will be generated.
2. If an outdoor workout mode is started from the Mi Fitness App, make sure the Mi Fitness App is running in the background and remains connected to the band. If the Mi Fitness App becomes disconnected from the band or is cleared by the system, the workout may be forcibly ended on the band, resulting in no workout data being generated.
3. Outdoor workout relies on the phone's GPS to record the workout track and distance. Therefore, make sure the phone is powered on with GPS and location permission for the Mi Fitness App enabled.
(1). iPhones: Go to [Settings] >> [Privacy & Security] >> [Location Services] >> [Mi Fitness App] >> [Always]. If the location permission is set to [While Using the App], the workout track or location data can be lost.
(2). Android phones: (Different phone models have different UI interactions). Using the Xiaomi/REDMI phone as an example, go to [Settings] >> [Apps] >> [Mi Fitness App] >> [App permissions] >> [Location] >> [Allow all the time].
Q12: Why can’t the workout record be viewed on the Xiaomi Smart Band 11 Active after starting a workout using the Mi Fitness App?
A: Workouts initiated from the Mi Fitness App will not sync the workout report to the Xiaomi Smart Band 11 Active. Only workouts starting from the band can be viewed in the workout records on the band. Therefore, if you need to view workout records on the band, please start the workout from the band.
Q13: Why are the three-ring data on the Mi Fitness App and the Xiaomi Smart Band 11 Active inconsistent?
A: If the difference is relatively small, it is because the data on the Xiaomi Smart Band 11 Active is synchronized once per minute, while the automatic synchronization interval with the phone is 30 minutes. Please manually tap [Sync] and check the data again.
If the difference is significant, it may be because the data in the Mi Fitness App comes from other devices, while the data on the band only comes from the data recorded by the band itself.
Q14: Does the Xiaomi Smart Band 11 Active support swimming style recognition? What swimming styles can it recognize?
A: The Xiaomi Smart Band 11 Active does not support the swimming style recognition feature.
Q15: Why is “Always Allow” location permission required when starting a workout on an iPhone while using the Xiaomi Smart Band 11 Active?
A: The following are the reasons why “Always Allow” location permission is required when starting a workout on an iPhone while using the Xiaomi Smart Band 11 Active:
On iPhones, location permissions are mainly divided into [Don’t Allow], [Allow While Using the App], and [Always Allow]. To ensure the completeness and reliability of exercise tracks and other exercise data, the Mi Fitness App requires [Always Allow] location permission before an exercise can be started normally.
Please note that even when [Always Allow] location permission is granted, the Mi Fitness App does not continuously access location information. Location information is only used in scenarios that require positioning, such as during exercise. If an exercise is started with only [Allow While Using the App] permission, there is a certain probability that location or exercise track data may be lost when the Mi Fitness App runs in the background, which can significantly affect the exercise experience.
In addition, because the Xiaomi Smart Band 11 Active does not support independent positioning, location information is obtained through the phone. If the phone does not have sufficient location permissions, the Xiaomi Smart Band 11 Active may also be unable to obtain location information properly. Therefore, to ensure that exercise data is recorded completely and accurately, [Always Allow] location permission is required on iPhones before starting an exercise. At the same time, new solutions are constantly explored, and the way to obtain permissions is continuously optimized.
Q16: Why is the calorie deviation of the Xiaomi Smart Band 11 Active so large?
A: The Xiaomi Smart Band 11 Active calculates calories based on your heart rate or wrist movement. The calorie calculation algorithm will be updated with each product iteration to consider more influencing factors. There are some differences between the calorie calculation logic of previous models and the latest calorie calculation method.
In wearable devices, the calories generated in a day are mainly composed of two parts:
1. Passively recorded calories, also called daily calories, refer to the calories that can be generated when no manual exercise is initiated. Calories will not increase when not wearing or sleeping. In other normal conditions, calories can be generated as long as there is a certain amount of activity. For example, in daily office work, although there are no steps, calories can be generated due to a certain amount of activity. Calories are related to the size and duration of activity.
Note:
The Xiaomi Smart Band 7 and earlier devices only generate calories when there are steps or heart rate data.
2. Actively recorded calories, also called exercise calories, refer to the calorie value generated when you manually initiate exercise. It is mainly related to heart rate and personal information. The higher the heart rate and the longer the exercise time, the more calories are generated.
If you think the calorie data is abnormal, you can submit feedback in the Mi Fitness App, and the relevant data will be analyzed.
Q17: How long can the Xiaomi Smart Band 11 Active store data independently?
A: The Xiaomi Smart Band 11 Active can store data independently. Some daily activity functions can be used without a phone. The phone only needs to be connected to the band via Bluetooth when synchronizing data. The band can display 20 workout records and store approximately 7 days of Stats, heart rate, and blood oxygen health data. The band can only display data from the current day.
For the sleep monitoring function, the band supports the [Advanced monitoring] and [Breathing score] features. Since these monitoring features generate a large amount of data, it is recommended to connect the band to the Mi Fitness App every day to synchronize the data and view complete sleep records.
If these two switches are turned off, sleep data can be stored for approximately 6–7 days. If either switch is turned on, sleep data can be stored for approximately 2–3 days.
It is recommended to connect the band to the Mi Fitness App every day to synchronize sleep data and avoid sleep data being overwritten in a cycle due to the device's storage limitations. After the data is synchronized with the Mi Fitness App on time, complete daily sleep data can be viewed in the Mi Fitness App.
