A: When you use the Mi Fitness APP to search for the band, a prompt displays that the device has been bound. Another possible situation is that the APP searches for someone else's band instead of yours. During normal binding, when the APP searches for an uninitialized band, the band will vibrate and display a prompt "Confirm on your phone".The troubleshooting steps are as follows:1. If you are using the band for the first time, please check whether the band is in the pending binding state. In the pending binding state, the band interface will prompt "Scan to download app";2.

14. Q: Does the phone’s Bluetooth need to be kept on when using the Xiaomi Smart Band 9 Active?
A: When using the Xiaomi Smart Band 9 Active:1. Pedometers, sleep & heart rate monitoring, stress/blood oxygen detection, and women's health 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, calendar, etc. do not require Bluetooth to be turned on all the time.Note:1. In order 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] >> [Notifications and calls] >> [Background permissions];2. iOS phones cannot add background protection to applications. If an 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 (weather, sports health data synchronization, schedule, etc.) need to be reopened on the phone to use the Mi Fitness APP;3. When iOS phones turn on power saving mode, the system Bluetooth connection stability will deteriorate and disconnection will occur.
15. Q: Why does the Xiaomi Smart Band 9 Active not synchronize data when it is disconnected from the iOS phone for a long time?
A: If the Mi Fitness APP is running too much in the background, it will be cleared and the device will be disconnected from the APP, resulting in data synchronization failure. You need to enter the Mi Fitness APP to automatically reconnect and synchronize data. When the APP is cleared in the background, reopening the APP will automatically reconnect to the device and you can use it normally.Reasons for clearing 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 4GB. 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 occupies 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 low power mode. Otherwise, the CPU will be actively downgraded, and the frequency of background clearing will increase significantly;2. Open the iOS phone'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 and put into the background, re-entering the APP will display the following two operation interfaces in order: first display the APP startup interface, then display the APP home interface;2. If the Mi Fitness APP is not cleared in the background, the interface where you operated before exiting the 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 check:1. Check whether the Mi Fitness APP is cleared in the background. If so, reopen it;2. Check if the Bluetooth on your phone is turned off and turn it back on;3. Check whether the distance between the band and the mobile phone is too far, causing the disconnection. Make sure the Bluetooth of the mobile phone is turned on, open the Mi Fitness APP and tap to connect manually.
16. Q: Why can't the current phone reconnect to the Xiaomi Smart Band 9 Active after logging into the same Xiaomi Account on multiple phones? Why is the device not available on the workout and health APPs?
A: There are several reasons:1. The current phone cannot reconnect. The old phone has unbound the device, 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 and 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 such device 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, 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 the 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.
17. Q: Why does the Xiaomi Smart Band 9 Active show disconnection when connected to the device?
A: The Mi Fitness APP is cleared in the background, so please confirm whether all background running permissions of the APP are enabled. There are two setting paths:1. After the device and APP are connected for the first time, tap the [Settings] option;2. After pairing, go to the Mi Fitness APP >> [Device] >> [Notifications and calls] >> enable background running permissions and follow the instructions. Select the setting method and check whether the permissions of [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 the latest version and update it to the latest version;2. Check whether all permissions of the APP have been granted, especially the Bluetooth connection permission;3. Check if the Bluetooth on your phone is turned off and turn it back on;4. Check whether the distance between the band and the mobile phone is too far, causing the disconnection. Make sure the Bluetooth of the mobile phone is turned on, open the Mi Fitness APP and tap to connect manually.
18. Q: Why can’t the Xiaomi Smart Band 9 Active be searched when paired with a new phone after it has been unilaterally restored to factory settings?
A: Check as follows:1. When an iOS phone is connected to a device and the device is unilaterally restored to factory settings, the iOS phone system Bluetooth will try to reconnect to the device, and the new phone cannot be able to search it (the iOS phone 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 be searched). You need to enter the iOS phone system Bluetooth settings, find the corresponding connected device, and ignore this device. At this time, use the new phone to search and pair it;2. When the Android phone is connected to the device and the device 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 device. Tap [Remove] and then search and connect with the new phone.
19. Q: What to do if the Xiaomi Smart Band 9 Active cannot be searched when rebinding after unbinding?
A: Manually turn off the Bluetooth switch of the mobile phone system, and restart the band and the mobile phone.
20. Q: What to do if three "×" signs appear on the Mi Fitness APP's binding interface when binding the Xiaomi Smart Band 9 Active to iOS phones?
A: If the following phenomenon occurs, please open the Bluetooth settings of the mobile phone system to check whether the current device 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.
21. Q: How to connect the Xiaomi Smart Band 9 Active to a new phone?
A: If you need to bind the band to a new phone, you can refer to the following scenarios:1. The account logged in the Mi Fitness APP by the new and old phones is the same and the old phone is an Android phone.After tapping [Connect new phone] on the band, turn off Bluetooth on the old Android phone and close the APP, then use the new phone to scan the code or add the device to search and add, and then connect. It should be noted that if the old phone does not need to connect to the band anymore, it is recommended to uninstall the APP, otherwise, the old phone will connect to the band again;2. The account logged in the APP by the new and old phones is the same and the old phone is an iOS phone.After connecting to the new phone on the band, the old iOS phone needs to tap to ignore the band name or turn off Bluetooth directly in the Bluetooth list, and then close the APP and use the new phone to scan the code or add the device to search and add, and then connect.

11. Q: Why does the Xiaomi Smart Band 9 Active display a default icon when receiving a message?
A: The band notification icon supports dynamic caching of 20 icons. If the 21st message is received when 20 icons are cached, the band will delete the application icon that has not received the message for the longest time and cache the new icon when it needs to request the icon. 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.

A: The band 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.
4. Q: Why is it difficult to fasten the buckle of the Xiaomi Smart Band 9 Active?
A: To ensure that the band is not easy to get loose after the band buckle is fastened, the buckle and the band hole are interference fit. Assembly method: put the band body on the wrist, pass the long band strap through the tail bezel of the short band strap, and adjust the band to suitable tightness. When fastening the buckle, the mushroom head of the buckle should be aligned with the band hole. The index finger should be placed under the long band, and the thumb and index finger should be pressed hard to fasten the buckle.

A: When wearing the band, be careful to avoid scratching the short end of the band (the buckle end) with hard objects to prevent the buckle from being disengaged due to accidental contact with the band. The band is designed with a wrist-like arc structure. If the buckle is accidentally touched and loosened, it will not fall off automatically without external force. Just tighten the buckle in time.

7. Q: Can the Xiaomi Smart Band 9 Active be worn with metal or mineral jewelry? Will the surface be damaged?
A: The base material of the band shell is plastic, and the outer surface is plated with high-gloss metal paint, so the band is essentially a plastic product. When worn together with harder metal accessories (such as metal bands or other irregular metal accessories) or mineral accessories (such as jade bands, crystal bands), the band surface will be scratched, dented, abraded, and the paint will fall off. Therefore, it is not recommended to wear the band and metal or mineral accessories together. You can wear them separately on both wrists.
8. Q: Is the white strap of the Xiaomi Smart Band 9 Active resistant to dirt? What are the cleaning methods?
A: The white strap is made of antibacterial TPU material. Compared with the black strap, the white strap is more likely to show various dirt and dyes in daily life. In daily use, please try to avoid contamination with red ink, watercolor pen and various industrial dyes. If it is accidentally stained, it is recommended that you use laundry detergent, soapy water and other daily cleaning agents to wipe the strap to remove the dirt.

1. Q: Does the Xiaomi Smart Band 9 Active support sleep monitoring? What is the monitoring range?
A: The Xiaomi Smart Band 9 Active supports sleep monitoring, which can record long sleep and sporadic naps, all of which are monitored 24 hours a day. After wearing the band normally and falling asleep, the band can automatically identify the sleep state through the built-in sensor.Sleep duration greater than or equal to 3 hours will be recorded as long sleep, while sleep duration less than 3 hours will be recorded as sporadic naps (sleep duration less than 20 minutes cannot be recorded).The band supports advanced monitoring of sleep throughout the day. After turning on, it can track the distribution of rapid eye movement (REM) sleep, but the battery life of the device will be severely reduced. After turning on high-precision monitoring, the amount of data generated by the monitoring function is large. It is recommended to connect to the Mi Fitness APP to synchronize data every day and view the complete sleep record.How to view sleep records: You can view the main sleep records of the day on the band. After the band is connected to the phone to synchronize data, you can tap [Sleep] in the Mi Fitness APP to view historical sleep data, including day, week, month, and year. View sleep distribution, including total sleep time, wake time, light sleep time, and deep sleep time. You can also view the sleep status at each time point during the daily sleep period. Rapid eye movement (REM) state needs to be turned on for auxiliary sleep monitoring to be recorded.Note: If the band is in a relatively quiet state and there are movements similar to sleeping, the sensor will judge it as sleeping, resulting in errors in the sleeping time.
2. Q: Does the Xiaomi Smart Band 9 Active support sleep breathing score?
A: Yes.The principle of sleep breathing score: Snoring or other diseases after sleep (such as obstructive sleep apnea) can cause a significant decrease in blood oxygen saturation. The device determines whether there is shortness of breath during sleep by monitoring the decrease in blood oxygen saturation and sleep quality during sleep. According to the number of times shortness of breath occurs, the corresponding sleep breathing quality score will be given in the Mi Fitness APP. If the sleep breathing quality is poor, it will cause daytime fatigue and drowsiness.Due to the large amount of data generated by the monitoring function, it is recommended to connect to the Mi Fitness APP to synchronize data every day and view the complete sleep records.Turning on sleep breathing score will significantly reduce the battery life of the band. Please choose whether to turn it on according to your personal needs.Open path:Mi Fitness APP: home interface >> [Sleep] >> tap the three dots icon in the upper right corner >> [Settings].Band: Sleep APP >> [Set] >> [Breathing score].
3. Q: Why is there no sleep data when swiping to the sleep widget of the Xiaomi Smart Band 9 Active after waking up?
A: When you use the Sleep APP during sleep, the band recognizes you are awake and checks the sleep data of the band, and it will also record your wake-up time.The swiping of the sleep widget can be caused by accidental touches after falling asleep. In order to prevent accidental touches, when the algorithm has not fully recognized that you have woken up, swiping the sleep widget will not record your wake-up and refresh your sleep data. Therefore, the data on the sleep widget when you just wake up is not in line with your expectations.
4. Q: Why is there no monitoring record or score in the Mi Fitness APP after turning on sleep breathing score of the Xiaomi Smart Band 9 Active?
A: First, confirm whether the sleep breathing score is turned on in the Mi Fitness APP. To turn it on, go to [Device] >> [Fitness and health] >> [Sleep] >> [breathing score] and tap to turn it on.If the sleep time is too short and the effective monitoring time is too short, the sleep breathing quality score or monitoring data will not be displayed (the night sleep time is more than 3 hours).Improper wearing will result in failure to monitor sleep breathing quality. It is recommended that the device be worn loosely and one finger away from the wrist bone.If none of the above reasons exist, please check whether the APP and firmware versions are the latest. It is recommended to restart the band or unbind and rebind it.
5. Q: How long does it take for the Xiaomi Smart Band 9 Active to complete a single blood oxygen saturation measurement?
A: About 15-60 seconds.Timeout reasons: Wearing status, skin characteristics, environment and other factors will cause measurement timeout.Measuring tips: Adjust the band to ensure the back is snug against your wrist.
6. Q: What changes will occur in the sensor indicator at the bottom of the Xiaomi Smart Band 9 Active when measuring blood oxygen saturation?
A: The red indicator and infrared light (invisible to the naked eye) will turn on, and if the indicator flashes green, it means that it is measuring heart rate.
7. Q: Why there is a red indicator on the Xiaomi Smart Band 9 Active flashing when it is not worn at night?
A: The summary is as follows:The Xiaomi Smart Band 9 Active has the all-day blood oxygen function turned on. It will automatically measure blood oxygen after falling asleep, and the red light on the band will flash. If you don't wear the device and find the red light flashing, it is a wrong detection of the wear monitoring function. The Xiaomi Smart Band 9 Active uses an infrared + green light + red light high-precision PPG heart rate sensor. Compared with traditional wear monitoring, the monitoring accuracy has been greatly improved. However, when the band is placed in an environment similar to the wrist, a wrong detection will also occur.When the band is not worn, please make sure that there is no object blocking the heart rate sensor (common wrong detection scenarios: the band is placed in a bag, on the bed/table, etc.).If you don't wear the band when you sleep, it is recommended to turn off the sleep advanced monitoring function, which can greatly save the power of the band. After turning on advanced monitoring, due to the large amount of data generated by the monitoring function, it is recommended to connect to the Mi Fitness APP to synchronize data every day and view the complete sleep record.
8. Q: Will there be an abnormal blood oxygen alert on the Xiaomi Smart Band 9 Active when there is risk?
A: You can set low blood oxygen alert (80%, 85%, 90%) on the Xiaomi Smart Band 9 Active. The measured values are for reference only and are not intended for medical reference or diagnosis. If you feel any discomfort, please consult a medical institution.
9. Q: What to do if the blood oxygen saturation measurement value on the Xiaomi Smart Band 9 Active is very low?
A: The summary is as follows:1. The wearing position is incorrect. Since there are fewer blood vessels in the wrist, the blood oxygen value is not easy to measure. Please wear the band one finger away from the wrist bone (ulna protrusion);2. Wear the band too loosely. Please wear it tighter, with a slight sense of tightness, and it is best if the band does not move when you shake your wrist;3. Stretch your forearms and open your elbows to avoid squeezing blood vessels, which can cause blood flow obstruction and unreliable measurements;4. Place your arm on a stable surface such as a desktop for measurement, with the band screen facing upwards to avoid shaking that will cause unstable signals;5. It is recommended to move the band to ensure that the back of the band fits your wrist and keep it still before measuring again;6. The latest version has been optimized accordingly. Please upgrade to the latest version for further experience.
10. Q: Does the Xiaomi Smart Band 9 Active support the standing reminder?
A: Yes. After turning on the standing reminder 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 up. If you recognize standing and walking within 10 minutes after the reminder, a finished standing reminder will pop up.Sitting for a long time and not moving can lead to many health problems. It is recommended to stand up and move once every hour when wearing the band. Standing up regularly is a convenient way to reduce sedentary behavior and increase energy consumption. You can only turn on the standing reminder from the Mi Fitness APP, set the start and end time, and set the lunch break to do not disturb.To turn on the standing reminder, go to [Device] >> [Fitness and health] >> [Standing] >> turn on/off >> set time period. 
11. Q: Why does the Xiaomi Smart Band 9 Active pop up a standing reminder even when standing all the time?
A: The purpose of the standing reminder is to get you moving. The band needs to detect wrist movement and step count to determine whether the standing activity behavior has been achieved. Therefore, if you have been standing still or moving slightly, you will receive a standing reminder. At the same time, the standing determination algorithm is also constantly optimized to gradually improve the using experience.
12. Q: Why does the Xiaomi Smart Band 9 Active suddenly receive a reminder to stand up when just starting to move?
A: The judgment of standing reminder requires certain conditions. If you just start to move and suddenly receive a standing reminder from the wearable device, it is because you are in an active state, however, have not reached the judgment threshold of standing activity behavior. At this time, you can continue to move and ignore the standing reminder issued by the wearable device. If this phenomenon occurs frequently, you can submit relevant feedback. The standing determination algorithm is also constantly optimized to gradually improve the using experience.
13. Q: Can the Xiaomi Smart Band 9 Active be connected to a body fat scale?
A: Not support.
14. Q: When will the heart rate sensor on the Xiaomi Smart Band 9 Active be enabled?
A: The Xiaomi Smart Band 9 Active PPG sensor detects heart rate using 25Hz green light detection, and heart rate cycle detection will detect heart rate status regularly. The detection time is short and the detection is accurate.
15. Q: Why is there no heart rate monitoring record on the Xiaomi Smart Band 9 Active?
A: Please check as follows:1. First, check whether the green light flashes when the back of the band touches the skin. If the green light flashes, it means that the heart rate monitoring function of the band is turned on normally. If there is no green light flashing, please verify whether the heart rate monitoring function is turned on;2. Please wear it in the correct way. The band should not be worn too loosely. Adjust the wearing method, and then re-enter the heart rate function of the band to check;3. Dry skin and skin scars can affect heart rate measurement. Low temperatures in winter can also affect heart rate measurement;4. If the above reasons are not the causes of the problem, you can restart the band, change the arm and try measuring again.
16. Q: Does the Xiaomi Smart Band 9 Active support abnormal heartbeat reminders?
A: Not support.
17. Q: Why are the vitality scores on the Xiaomi Smart Band 9 Active and the Mi Fitness APP inconsistent?
A: When the vitality score on the Mi Fitness APP is greater than that on the band, the APP will send the data back to the band. Since the current 30-minute data is sent back to the band, the data will not be displayed on the band. So the strategy is updated to not send back the current 30-minute data to the device, and only send back the vitality score other than the current 30 minutes on the same day. Therefore, there will be a half-hour error in the fusion and delivery of the vitality score.
18. Q: How to check the vitality score of the Xiaomi Smart Band 9 Active?
A: The Xiaomi Smart Band 9 Active does not support the vitality score function currently.

10. Q: What to do if the distance error of outdoor sports is large or there is no track after the exercise with the Xiaomi Smart Band 9 Active?
A: Since the band does not have an independent positioning function, the positioning information and trajectory data all come from the mobile phone, so this type of outdoor sport requires turning on the mobile phone positioning information and connecting to the mobile phone. The method to turn on the mobile phone positioning information is as follows:1. Before using the band for outdoor sports, Android phones should set the location permission of the Mi Fitness APP to [Always] or [While using the app] and turn on [Background permissions] on the APP device interface. Otherwise, there will be no movement track after the exercise and the distance will be inaccurate. When the location permission is set to [While using the app] or the Mi Fitness APP is in the background, the outdoor exercise distance will have a large error or there will be no track after the exercise;2. Before using the band for outdoor sports, iOS phones should set the location permission of the Mi Fitness APP to [Always] and go to [Settings] >> [Mi Fitness] >> turn on [Background App Refresh]. Otherwise, there will be no exercise track after the exercise and the distance will be inaccurate;3. When the positioning information of the mobile phone is turned on normally and the track is displayed in the exercise record of the Mi Fitness APP, however, the distance still deviates, you can zoom in on the track of the exercise record to see if there is a long straight line in the exercise track. This phenomenon is caused by obstructions around, resulting in deviations in the positioning information of the mobile phone, which in turn causes deviations in the distance calculation of the band. As shown in the figure, similar scenarios will lead to inaccurate exercise distance calculation.
11. Q: Why does the Xiaomi Smart Band 9 Active not generate exercise data after exercising?
A: The Xiaomi Smart Band 9 Active will not save exercise records. This is caused by the following reasons:1. Make sure the band is fully charged during exercise. If the band is turned off or restarted during exercise, no exercise data will be generated;2. If you enable outdoor sports on the Mi Fitness APP, please make sure the APP is running in the background and remains connected to the band. If the APP is disconnected from the band or the APP is cleared, the band will be forced to exit the sports function and no sports data will be generated;3. Outdoor sports rely on the mobile phone’s GPS to record the track and exercise distance. Therefore, when doing outdoor sports, you need to turn on the mobile phone’s GPS and APP location permissions.iOS phone: [Settings] >> [Privacy & Security] >> enable [Location Service] >> scroll down to find the Mi Fitness APP >> turn on [While Using the App] (If the APP location permission is set to [While Using the App], it can cause loss of track and location).Android phone: (Different phone models have different UI interactions). The following takes the Mi Fitness APP as an example: [Profile] >> [App permissions] >> [Access location].
12. Q: Why can’t the exercise record be viewed on the Xiaomi Smart Band 9 Active after starting an exercise using the Mi Fitness APP?
A: Exercises initiated from the Mi Fitness APP will not synchronize exercise reports to the band. Exercises initiated from the band can only be viewed on the band. So if you need to view exercise records on the band, please initiate the exercise from the band.
13. Q: Why are the three-ring data on the Mi Fitness APP and the Xiaomi Smart Band 9 Active inconsistent?
A: 1. If the difference is small, it is because the data on the band is synchronized once a minute, and the automatic synchronization interval with the mobile phone is 30 minutes. Please manually Tap on the synchronization and check again;2. If the difference is large, it is because the APP data comes from other devices, and the band data only comes from the data recorded by the band.
14. Q: Does the Xiaomi Smart Band 9 Active support swimming style recognition? What swimming styles can it recognize?
A: Not support.
15. Q: Why do location permissions of the Xiaomi Smart Band 9 Active always need to be allowed when initiating an exercise on iOS phones?
A: Location permissions are mainly divided into rejection, permission during use, and always allowed location permissions. In order to ensure the integrity and reliability of sports data such as trajectories during exercise, the Mi Fitness APP has set a requirement that the always allowed location permission must be obtained before the exercise can be initiated normally. Please note that when the always allowed location permission is granted, the APP will not continue to obtain your location information, and it will only be used in scenarios where positioning is required, such as exercise status. If you initiate an exercise with only the in-use permission granted, when the APP enters the background state, there will be a certain probability that problems such as positioning and trajectory loss will occur, which will seriously affect the exercise experience. In addition, for wearable devices that do not support independent positioning, the acquisition of positioning information depends on the mobile phone. If the mobile phone's positioning permission is insufficient, problems such as the wearable device being unable to obtain positioning information will also occur. Therefore, in order to ensure the complete and correct recording of exercise data, the band requires the granting of the always allowed location permission on iOS devices before initiating an exercise. At the same time, new solutions are constantly explored and the way to obtain permissions is continuously optimized.
16. Q: Why is the calorie deviation of the Xiaomi Smart Band 9 Active so large?
A: The Xiaomi Smart Band 9 Active calculates calories based on your heart rate or wrist movement. The calorie calculation algorithm will be updated with each product iteration to take more influencing factors into consideration. 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 and the relevant data will be analyzed.
