4. Q: What are the differences between the Xiaomi Smart Band 9 Standard and the NFC version?
A: The differences between them are as follows:
1. The Xiaomi Smart Band 9 NFC version adds an NFC chip compared to the Xiaomi Smart Band 9, enabling it to swipe public transit cards and simulate access cards. It supports simulating door cards with unencrypted frequencies of 13.56MHz (IC cards) available on the market. However, cards with encrypted areas can only copy the card number and cannot guarantee full functionality for card swiping. Due to security reasons, bank cards with access card functions and cards used for stored value or public transit cannot be simulated temporarily. Even if successfully simulated, this feature cannot provide additional functions such as banking, financial transactions, or public transit;
Note:
1. Due to different mechanisms and standards for access card authentication in the market and varying card permissions managed by property management, the successful simulation of a card does not guarantee its normal use. Some access cards and systems are not designed according to NFC standards, which can result in successful simulation but unsuccessful card swiping. If multiple attempts to swipe fail, using a physical access card is recommended.
2. The Xiaomi Smart Band 9 features a metal buckle with a CD pattern, whereas the Xiaomi Smart Band 9 NFC features a metal buckle with a matte finish.

3. If steps A and B still fail to establish a connection, try toggling the phone's Bluetooth on and off and then reopen the Mi Fitness APP to search and reconnect.

7. Q: Why does the Xiaomi Smart Band 9 experience Bluetooth disconnection on iOS/Xiaomi/Redmi/other Android phones?
A: The Xiaomi Smart Band 9 utilizes Bluetooth wireless technology to connect with phones. Wireless connections are susceptible to factors such as distance, radio frequency interference, and obstructions, which will lead to intermittent disconnection between the band and the phone. In such cases, the band is designed to automatically reconnect with the phone when it returns within range.
If automatic reconnection does not occur upon returning within range, please follow these steps for recovery:
1. Verify that the location permission for the Mi Fitness APP is set to always allow. Only when set to always allow can the APP initiate the reconnection action when the band returns within range;
2. Try force closing the APP and then restarting it;
3. Attempt to turn off the Bluetooth on the phone and then turn it back on;
4. In the phone's Bluetooth settings, select the band device and unpair it. Returning to the APP to initiate reconnection and confirm the prompt when it appears to complete the reconnection process.

8. Q: What to do if the Xiaomi Smart Band 9 cannot reconnect to the Mi Fitness APP?
A: To resolve the issue, here are some steps as follows:
1. Try to remove the Mi Fitness APP and then restart it;
2. Attempt to turn off the Bluetooth on the phone and then turn it back on;
3. Choose the band device in your phone's Bluetooth settings and remove the pairing. Afterward, go back to the APP to start the reconnection process. Confirm the prompt once it appears to finish the connection.

9. Q: What to do if the phone prompts that the device has been bound to another account or APP when binding?
A: When the APP is used to search for the band and a prompt appears indicating that the device has been bound. Another possible scenario is that the APP has detected a different band, not the one belonging to the current account holder. During a normal binding process, upon detecting an uninitialized band, the band will vibrate and display a prompt asking [Received binding request, do you allow?]
To solve this problem, here are the troubleshooting steps：
1. If the band is being used for the first time, check if the band is in a state ready for binding. In this state, the band page will prompt [Download the app to pair band] ;
2. Check if the band vibrates and displays the prompt [Received binding request, do you allow?] during the binding process. If the band does not prompt, then the device being connected is not yours. Check if there are other band devices nearby;
3. After the band vibrates and prompts normally, tap on the [√] to bind. After successful binding, the Mi Fitness APP on your phone will display [Successfully added] and the band will display the home screen.

10. Q: Does the Xiaomi Smart Band 9 support proximity discovery and pairing?
A: Yes, it does. Only the MIUI system will pop up a window for device discovery. When a new band that hasn't been paired is brought close to the phone, the phone will display a pop-up with the device model, Bluetooth address and device image.
To achieve this function, the following conditions need to be met:
1. On the phone, network, Bluetooth and Quick Connect need to be turned on for band searching to begin. The Quick Connect activation path is [Bluetooth] >> [Additional settings] >> [Pair compatible devices];
2. The band should be in an unpaired state;
3. Distance between the band and phone is recommended to be within 1 meter.

11. Q: Does the phone’s Bluetooth need to be turned on all the time when using the Xiaomi Smart Band 9?
A: You can refer to the following steps for Bluetooth usage:
1. Step counting, sleep & heart rate monitoring, stress/blood oxygen monitoring, vitality scores, breathing training and women's health management can record data independently without the need for a constant Bluetooth connection. However, regular connection to the phone is necessary to sync health data. It is recommended to connect the phone during exercise to record the trajectory;
2. Functions such as stopwatch, alarm, Pomodoro, calendar, world clock, etc., do not require the Bluetooth to be constantly turned on;
3. Functions like call reminders, APP notification reminders, find phone, events reminder, weather, find device, control phone music playback, remote control phone photography, etc., require Bluetooth to be turned on to maintain communication with the band and phone.
Note:
1. For better usage of the band, it is recommended to keep the Mi Fitness APP running in the background. To avoid memory cleaning and interference from some management software on Android systems, please follow the instructions on the App: [Mi Fitness] APP >> [Device] >> [Enable background running permission];
2. iOS cannot perform background protection for APPs. When the APP is removed in the background, the Bluetooth connection will not be disconnected and message notifications can be used normally. However, other sync data APPs such as weather, health data sync, schedule, etc. will require reopening the Mi Fitness APP;
3. Enabling power-saving mode on iOS will result in decreased Bluetooth connection stability and potential disconnection issues.

12. Q: Why does the Xiaomi Smart Band 9 experience unsynchronized data when in a prolonged disconnected state with an iOS phone?
A: When APPs run in the background for an extended period, they will be removed, causing the device to disconnect from the Mi Fitness APP and preventing data synchronization. To sync data, you need to enter the Mi Fitness APP for automatic reconnection and data synchronization. After the APP is removed in the background, reopening it will automatically reconnect the Xiaomi Smart Band 9 for normal synchronization.
The occurrence of being removed in the background is primarily due to the APP using up the RAM. To free up sufficient resources for newly opened APPs, the system needs to terminate some background-running APPs to free up RAM. The frequency of being removed in the background varies depending on the device model and iOS software version. For example, on an iPhone 12 with 4GB of RAM, running 4 apps will lead to being killed in the background on iOS 16.3.1. However, on the iOS 16.4 official version, running 5-6 APPs does not lead to being killed in the background. This varies depending on specific APPs, such as the camera APP which consumes relatively more memory.
To reduce the frequency of being killed in the background during normal usage, consider the following two points:
1. Ensure sufficient battery power to avoid overheating of the phone and disable low-power mode. Insufficient battery power, severe overheating, or running the phone in low-power mode will significantly increase the frequency of background APP termination;
2. Open [Settings] >> [General] >> [Background APP refresh] on your phone and enable this feature.
To determine whether the APP has been removed in the background by the system, please refer to the following operation:
1. If the Mi Fitness APP has been removed in the background, reopening it will follow these two steps: first, display the APP launch page, then display the APP's homepage;
2. If the Mi Fitness APP has not been removed in the background, reopening the APP will resume the previous operation before exiting.

13. Q: Why can't the current phone reconnect and why is the Mi Fitness APP not showing the Xiaomi Smart Band 9 when multiple phones are logged into the same Xiaomi account?
A: Here are several reasons for this issue:
1. The current phone cannot reconnect because the old phone has unbound the device and the new phone has not synchronized the account. Therefore it cannot reconnect to this device;
2. Check which screen the band is displaying. If it's on the QR code screen or language selection screen, unbind the device from the Mi Fitness APP on your phone and then re-scan to pair;
3. Make sure the [Bluetooth] icon on the band is constantly on. If it is, use the [Find phone] feature to check if it's connected to the current phone. If not, unbind the device from the APP and then rebind it with the current phone;
4. If the device is not shown on the old phone's Mi Fitness APP device management page, it means the old phone has unbound the device. After logging in with the same account on the new phone and syncing, the band will not be displayed. If the band is on the QR code screen or language selection screen, re-scan to pair;
5. When connecting the band to two phones using the same Xiaomi account, after resetting the band, pair it again with the new phone and turn off Bluetooth on the old phone. If the new phone still cannot reconnect, it is because the new phone did not automatically retrieve new login and pairing information.
To avoid this issue, here are some suggestions as follows:
1. Try to avoid logging in with the same account on multiple phones;
2. If there is already a situation where you cannot connect back, turn off Bluetooth on other devices logged in with the same account and then try again;
3. Ensure a stable network connection and restart the APP after removing it to trigger the re-delivery of login and pairing information from the cloud, ensuring the band can reconnect.

14. Q: Why does the Xiaomi Smart Band 9 show disconnected when connecting to a device?
A: It is because the Mi Fitness APP was removed in the background. Please check if you have enabled all background running permissions for the APP.
Here are two ways to set the permissions:
1. After the device and Mi Fitness APP are first connected, tap the [Go to settings] to set the permissions;
2. Open the [Mi Fitness] APP >> [Device] >> [Background permissions] to set the permissions. 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.

15. Q: Why can't the Xiaomi Smart Band 9 be found when pairing with a new phone after it has been reset to factory settings?
A: To resolve this issue, please troubleshoot as follows: 
1. When the band is connected to an iOS phone and it is reset to factory settings, the iOS phone's Bluetooth will attempt to reconnect to it. This can result in the new phone being unable to find the band because the iOS phone and the band will keep connecting and disconnecting. During the connection period, the new phone cannot search for the band. If the new phone is in scanning mode when in the disconnection period, it will find the band. To resolve this, go to the iOS phone's Bluetooth settings, find the previously connected band and tap [Forget this device]. Then, use the new phone to search and pair with the band;
2. When the band is connected to an Android phone and it is reset to factory settings, the Mi Fitness APP will reconnect to the band and prompt the account holder to either [Remove this device] or [Add]. In this case, the new phone cannot find the band. Select [Remove this device] and then use the new phone to search and connect.

16. Q: Why the Xiaomi Smart Band 9 cannot be found during search when trying to rebind after unbinding?
A: Manually toggle the Bluetooth switch on the phone's system settings and restart both the band and the phone.

17. Q: What to do if the Mi Fitness APP shows three [×] marks on the binding interface, indicating binding failure when trying to bind the Xiaomi Smart Band 9 on iOS?
A: If encountering this situation, open the Bluetooth settings on the phone to check if the Xiaomi Smart Band 9 is already connected.
If the Xiaomi Smart Band 9 is already connected, please tap on the small circle next to [Connected] and then select [Forget this device].
Note:
If these steps do not fix the issue, it is recommended to restart the band and the phone's Bluetooth, and then retry after restarting the phone.

The pebble mode + necklace pendant accessories
1. Q: How to use the Xiaomi Smart Band 9 necklace mode?
A: We offer a fashionable necklace pendant that prioritizes accessory style. The device can be worn as a pendant for improved aesthetics and presentation in this mode.
We provide several exquisite band displays specifically designed for necklace wear. These band displays offer superior visual effects on both the active and standby screens. For more details, please visit the [Manage band displays] and then go to [Necklace mode] section.

In this mode, the data of steps are supported for monitoring. However, the data items such as heart rate, blood oxygen, sleep, vitality score, calories and duration of medium-to-high intensity activities are not supported for monitoring. Due to the wearing style, detection accuracy cannot be ensured.
Note:
You cannot switch to necklace mode from the APP while in the middle of an exercise session, Pomodoro, or timer.

To assemble and disassemble the Necklace, here are some detailed steps as follows:
1. The main body of the band has two strap slots on both ends. On the side near the charging port, assemble the bead with the ring. The hook side should face the screen of the band. Insert the bead into the strap slot. Similarly, insert the bead without the ring into the other strap slot;
2. Align the charging port with the magnetic cover of the pendant backplate. Attach the backplate to the main body of the band;
3. Straighten both ends of the cord according to the position of the metal clasp. First, thread one end through the large ring of the bead, then through the small ring of the pendant. Pull the cord through, stretch it open, and thread the metal clasp end of the cord through. Tighten the cord to complete the assembly of the pendant;
4. Hold both ends of the metal clasp and press them towards the center. Rotate the left hand outward and the right hand inward to open the clasp;
5. Align the small dot on one end of the metal clasp with the notch on the other end. Press them together towards the center, rotate the left hand inward and the right hand outward to fasten the clasp;
6. Press the quick-release button to remove the bead with the ring. The bead without the ring has a notch for easy removal. Alternatively, you can detach the bead without the ring by pressing the quick-release button and using the weight to facilitate quick disassembly;
7. For subsequent assemblies, attach the beads to complete the process without needing to disassemble the cord.

2. Q: Why is the step count on the Xiaomi Smart Band 9 deviation larger in necklace mode?
A: The step count in necklace mode only supports daily walking. In other scenarios such as cycling or running, the larger movement will cause significant deviations in the step count. For more accurate results, it is recommended to refer to the step count while walking when using necklace mode.

3. Q: Why are there no exercise data and calories tracked in the necklace mode on the Xiaomi Smart Band 9?
A: For your reference, the reasons for this issue are as follows:
1. We offer a wearing mode specifically designed for necklace pendants. In this mode, the device functions as a pendant, enhancing aesthetic appeal and presentation. It only supports step count detection and does not support other exercise or health-related data items;
2. The Mi Fitness APP usage guide ([Mi Fitness] APP >> [Device] >> [Help center] >> [Usage guide]) notes the data items that can be monitored in the necklace mode and the special logic when the necklace mode is enabled. Please refer to the guide for more details.

4. Q: How to use the pebble mode on the Xiaomi Smart Band 9?
A: We offer a running posture recognition feature. By using a specific wearing method, you can obtain particular running posture information from the device, helping you analyze and improve your running form.
The detailed instructions for the installation and removal of the pebble mode are as follows:
1. To use the pebble mode, press the main body of the band into the pebble capsule in the correct orientation. Then press the shoe clip button at the bottom of the pebble capsule to release the spring clip, thread the shoe clip through your shoelaces from underneath and press to secure the spring clip;
Note:
After wearing, please check that the band display is oriented towards you. If the direction is incorrect, it will result in inaccurate data recording.
2. To remove the pebble mode, press the shoe buckle clip button at the bottom of the pebble capsule, release the spring clip and remove the pebble capsule from the shoelace. Use your fingertips or a pry piece to gently insert into the top or bottom of the pebble capsule and pull it out from the groove of the wristband body. Separate the wristband body from the pebble capsule.
The data items that support detection include running and cycling, detailed introductions are as follows:
1. Cadence refers to the frequency of footsteps during walking or running, representing the number of times the legs alternate per unit of time. It is a crucial factor in determining walking or running speed, expressed in steps per second. In race walking, cadence can reach 3.5 to 3.7 steps per second, while in sprinting it can reach 4.6 to 5.1 steps per second. Cadence is primarily influenced by the flexibility of the nervous system, the percentage of fast-twitch muscle fibers in the muscles, the coordination of the motor organs, muscle strength and contraction speed. These factors are largely innate but can be improved through scientific training;
2. Running styles with relatively high cadence are often referred to as cadence running while those with larger stride lengths are known as stride length running. Among elite runners, stride length is the key factor determining performance;
3. When the pace is fast and the cadence is too low, it indicates a larger stride length, which increases the risk of injury. When the pace is slow and the cadence is too high, it indicates a smaller stride length, resulting in lower running efficiency;
4. Ground contact time refers to the time it takes for a single foot's sole to make contact with and completely leave the ground during running, measured in milliseconds per footstrike;
5. Flight time, the duration during which the foot is simultaneously in the air while running, is measured in milliseconds;
6. The pebble mode supports detecting ground contact to flight ratio, the ratio of ground contact time to flight time during running;
7. The pronation range reflects the inward rotation angle of the foot from initial ground contact to the start of push-off. Rotation angles range between 5° to 25°, as extremes can increase the risk of sports injuries;
8. The pebble mode supports detecting landing techniques that are categorized as full-foot landing, forefoot landing, or heel landing;
9. The pebble mode supports detecting impact force at landing, the force experienced by the foot upon landing on the ground, which is also a potential factor contributing to sports injuries. Upon landing, the impact force can be approximately 1.15 times body weight, and upon full support, it will reach 2.0 to 3.0 times body weight. However, reducing running speed by 30 seconds per minute increases the force by 0.5 to 0.6 times body weight;
10. Cadence is measured by the number of revolutions per minute of the pedals;
The detailed instructions about the pebble mode are as follows:
1. To use the pebble mode, switch to it on the APP or wearable device. Follow the prompts to initiate outdoor running, indoor running, walking, or cycling on the APP's exercise page;
2. On the band, you need to tap [Settings] >> [Running mode] >> [Pebble mode] to switch it. On the Mi Fitness APP, you need to tap [Device] >> [Switch running mode] >> [Pebble mode] to switch it on;
3. If you want to exit the pebble mode, touch the screen to wake it up, swipe up to exit, and hold the arrow while sliding up to confirm exit.
Note:
1. This mode does not record heart rate, blood oxygen, or other similar data;
2. Ensure that the exercise session is initiated within the app to record exercise data.

5. Q: Why is it difficult to remove the Xiaomi Smart Band 9 when in the pebble mode?
A: The pebble is designed with soft rubber to wrap around the wristband for stability during running.
If you encounter difficulty in removing it, please follow these instructions:
1. The band has a curved surface with a quick-release groove. Use your fingernail to gently insert into the groove and pull the wristband;
2. If you still find it hard to remove the band even after locating the groove, open the user manual and take out the green pry piece (found in a transparent bag inside the manual). Gently push the pry piece forward into the groove. Use and store the pry piece carefully for future use.

6. Q: What to do if the clip of the pebble on the Xiaomi Smart Band 9 is lost?
A: If the pry piece is lost during use, you can use common flat plastic items found around the house to insert it into the groove of the band and assist in pulling it out. Try to avoid using sharp metal objects to prevent scratching the band. Suitable alternatives include a paper clip, a card, or a toothpick for assisting in disassembly.

7. Q: Why is there exercise data lost in the pebble mode when using the Xiaomi Smart Band 9?
A: If you encounter missing exercise data in the pebble mode, you can ensure the Mi Fitness APP is added to the background protection list. Additionally, ensure the APP has the necessary permissions enabled to allow the wristband functions to work correctly. Open the [Mi Fitness] APP >> [Device] >> [Background permissions] to set the permissions. 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.

8. Q: Why is there a discrepancy between the actual data and the recorded ground contact to flight ratio, step count, etc., in the pebble mode when using the Xiaomi Smart Band 9?
A: The pebble mode only supports wearing the band display towards oneself. There can be significant data differences if worn in the opposite direction, so please ensure the correct wearing orientation.
If you are running outdoors, discrepancies in data such as ground contact to flight ratio and step count will arise due to individual differences in running habits. The latest software version has been optimized to address this. Please upgrade to the latest version (1.1.122) for the best experience.
For indoor running, as actual movement is not occurring, the estimated exercise distance is based on personal information (height, weight, etc.) and exercise conditions, which will lead to data discrepancies. The APP will introduce a distance calibration feature, allowing manual adjustment of distance post-indoor running to correct stride length, pace, and other information for more reliable exercise records.

5. Q: What to do if the Xiaomi Smart Band 9 misrecognizes or cannot recognize the exercise after the Auto detect feature turns on?
A: 1. The Xiaomi Smart Band 9 supports the Auto detect feature. Enabling it can automatically detect activities such as running, walking, cycling, rowing, elliptical training, and jump rope.
In practical use, the accuracy and sensitivity of the Auto detect feature can vary depending on the individual and the posture and proficiency in the exercise.
If the exercise duration is very short or the posture changes frequently, the auto-detect function will not be triggered. Some daily scenarios, such as driving a car, taking a bus, or engaging in activities that are similar to exercise movements, could trigger false detection;
2. If the exercise scenario is not successfully detected, it can be due to insufficient exercise duration or improper exercise posture.

6. Q: Why does the Xiaomi Smart Band 9 prompt "Exercise detected, outdoor cycling" when not cycling outdoors?
A: Activities such as brushing teeth, pushing a baby stroller, chopping dumpling filling, or driving on bumpy roads can cause wrist movements similar to those of cycling. As a result, if these activities last for more than 3 minutes, they will be falsely recognized as cycling. Our engineers are constantly improving the algorithm to enhance your experience.

7. Q: How to adjust the order of the Xiaomi Smart Band 9 sports modes/sports events?
A: The Xiaomi Smart Band 9 supports 159 types of sports, which supports automatic adjustment of the order based on your usage frequency. The more frequent the use, the more advanced it is.

11. Q: What to do if there is a significant distance error or no trajectory after outdoor sports? Why does the Xiaomi Smart Band 9 outdoor sports require maintaining a Bluetooth connection on the phone?
A: Please upgrade to version 1.1.122 and above.
Due to the lack of an independent positioning function, the positioning information and trajectory data of the band come from the mobile phone. Therefore, this type of outdoor sport requires opening the mobile phone's positioning information and connecting it to the mobile phone for use.
For your reference, here are the methods to enable mobile location information:
1. Before using the band for outdoor activities, on the Android phone, you should select the positioning permission of the Mi Fitness APP as [Allow] or [While Using the App], and turn on [Enable Background Unrestricted] on the Device interface. Otherwise, there will be no movement trajectory and the distance will be inaccurate after the exercise ends. When the positioning permission is set to [While Using the App], or when the Mi Fitness APP is in the background, there will be a large error in outdoor exercise distance or there will be no trajectory after the exercise ends.
2. Before using the band for outdoor activities, on the iOS phone, you should select the positioning permission of the Mi Fitness APP as [Allow]. Go to [Settings] >> [Mi Fitness] >> turn on [Background App Refresh], or there will be no movement trajectory, and the distance will be inaccurate after the exercise ends.
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, but 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 could be 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.

12. Q: Why did the Xiaomi Smart Band 9 not generate exercise data after exercising?
A: The following reasons result in the Xiaomi Smart Band 9 not saving exercise records:
1. During exercise, if the band is turned off or restarted, no exercise data will be generated;
2. If outdoor sports are enabled on the Mi Fitness APP, please ensure that the app runs in the background and remains connected to the band. If the APP is disconnected from the band or the APP is hacked, it will cause the band to be forcibly exited and unable to generate motion data;
3. Outdoor sports rely on mobile GPS to record trajectories and distance. Therefore, when engaging in outdoor activities, it is necessary to turn on GPS and APP location permissions on the phone.
(1). iOS phone: Go to [Settings] >> [Privacy & Security] >> turn on [Location Services] >> scroll down and find the [Mi Fitness] APP >> enable [While Using the APP] (When the App location permission is set to While Using the APP, there will be situations where the track and location are lost);
(2). Android phone: Go to [Settings] >> [Apps] >> [manage apps] >> [Mi Fitness] >> [App permissions] >> [Location].

13. Q: Why the exercise history cannot be viewed on the Xiaomi Smart Band 9 after using a mobile app to initiate a workout?
A: The exercise initiated by the Mi Fitness APP will not synchronize the motion report to the band, and the motion record can only be viewed on the band by initiating the motion from the band. So if you need to check your exercise records on the band, please initiate the exercise from the band.

14. Q: Why are the three-ring data on the Mi Fitness APP and the Xiaomi Smart Band 9 inconsistent?
A: 1. If the difference is small, it is because the data on the band is synchronized every minute, and the automatic synchronization interval with the phone is 30 minutes. Please manually tap on the synchronization icon and check again;
2. If the difference is significant, it is because the data source of the app comes from other devices, and the data of the band only comes from the various data recorded by the band itself.

15. Q: Does the Xiaomi Smart Band 9 support swimming posture recognition? What swimming styles can be recognized?
A: It supports recognition of four swimming styles (breaststroke, backstroke, butterfly, and freestyle). The band will recognize the swimming posture in swimming mode and display the swimming posture you primarily use. If the swimming posture is not standard, the band will not display the swimming posture correctly. It is displayed as a medley when using more than one stroke.

16. Q: Why do the location permissions have to be allowed when launching a workout on the iOS phone?
A: The location permissions are mainly divided into Never, While Using the App and Allow.
To ensure the integrity and reliability of exercise data such as trajectory during exercise, the APP requires that you should obtain permission to Allow location before you can initiate exercise normally.
Please note that even if the permission to Allow location is granted, the APP will not continue to obtain your location information, and will only be used in scenarios where location is required, such as in motion.
If you initiate an exercise while using the App granted, when the App enters the background state, there is a certain probability that problems such as positioning and track loss will occur, which will seriously affect the exercise experience.
In addition, for the devices that do not support independent positioning, the acquisition of positioning information depends on the mobile phone. If the mobile phone’s positioning authority is insufficient, problems such as the device being unable to obtain positioning information will occur.
Therefore, to ensure the complete and correct recording of exercise data requires permission to Allow location on iOS devices before initiating an exercise. At the same time, Xiaomi is constantly exploring new solutions and optimizing the way to obtain permissions.

17. Q: Why is there a large deviation in the calorie records on the Xiaomi Smart Band 9?
A: The calorie calculation for the Xiaomi Smart Band 9 is based on your heart rate or wrist activity, and we will update the calorie calculation algorithm for each iteration of the product to take into account more influencing factors.
There are some differences between the previous calorie calculation method and the latest calorie calculation method, as follows:
In the 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. When not wearing or sleeping, calories will not increase; in other normal states, as long as there is a certain amount of activity, calories can be generated.
For example, in daily office work, although no steps are generated, calories can be generated due to a certain amount of activity. Calories are related to the size and duration of activity;
2. Actively recorded calories, also called exercise calories, refer to the calories generated when manually initiating 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 there is an abnormality in the calorie data, you can submit feedback.

1. Q: Does the Xiaomi Smart Band 9 support sleep monitoring and what is the monitoring range?
A: The band supports sleep monitoring, which can record long sleep and sporadic naps, both of which are 24-hour monitoring. After wearing the band to sleep, the band can automatically recognize the sleep status through the built-in sensor.
Sleep duration greater than or equal to 3 hours will be recorded as long sleep. Sleep duration less than 3 hours will be recorded as sporadic naps (sleep less than 20 minutes will not be recorded).
The band supports 24-hour advanced monitoring for sleep. When turned on this function, the band tracks the distribution of the REM sleep. However, its battery life will be severely reduced. Sleep data can be viewed on both the band and APP.
To view sleep records, please refer to the following method:
Support to view the sleep records in the band. After synchronizing the data between the band and the phone, you can tap [Sleep] in the APP to view the historical sleep data (including day, week, month, year), sleep duration (including total sleep time, awake time, light sleep time, deep sleep time), and the sleep stages of each time point in the sleep time period. The REM sleep is recorded only when assisted sleep monitoring is enabled.
Note:
When the band is in a relatively quiet state and shows a movement similar to sleep, the sensor will judge it as a sleep state, resulting in an error in the time of falling asleep. If you are watching TV, lying in bed and playing with a cell phone, or reading a book, the band not will record sleep accurately, as the movement amplitude and frequency in the above scenarios are relatively small and similar to that of sleep.

2. Q: Does the Xiaomi Smart Band 9 support the breathing score function for sleep?
A: The Xiaomi Smart Band 9 supports the breathing score function for sleep.
The principle of the breathing score is as follows:
Snoring or other diseases (such as obstructive sleep apnea syndrome) will lead to a significant drop in blood oxygen saturation when sleeping. The band determines whether dyspnea occurs during sleep by monitoring the drop in blood oxygen saturation and the quality of sleep. Depending on the dyspnea times, the corresponding breathing score will be given in the APP. If the breathing score is poor, it will lead to fatigue and sleepiness during the day.
Turning on the breathing score function will significantly reduce the ring life of the band. It is recommended to turn it on according to your needs.
To turn it on the APP, please check the following method:
[Mi Fitness] APP >> [Device] >> [Sleep] >> turn on [Advanced monitoring].
To turn it on the band, please check the following method:
Enter the main interface of the band >> go to [Sleep] >> [Settings] >> [Advanced monitoring].

3. Q: Why is there no sleep data in the sleep widget interface of the Xiaomi Smart Band 9 after waking up?
A: If you use the [Sleep] APP during sleep, the band will recognize that you have woken up and are checking the sleep data on the band. Also, it will be recorded as your wake-up time.
Please check whether the left and right sliding of the widget is caused by a mistaken touch after falling asleep. In order to prevent the sleep from completing by mistake, when the algorithm does not fully recognize the end of sleep, sliding the sleep widget will not record it as the end of sleep and refresh the sleep data, so you will see the data of the sleep widget is not displayed properly when you just wake up. The sleep data is refreshed as soon as you tap the sleep widget to enter the [Sleep] APP. After that, you can swipe to the widget again to view your sleep data.

4. Q: Why there is no monitoring record or score in the APP after the Xiaomi Smart Band 9 turns on the breathing score function?
A: 1. First of all, make sure the breathing score function for sleep is enabled in the APP (Path: [Mi Fitness] APP >> [Device] >> [Sleep] >> turn on [Advanced monitoring]);
2. If the sleeping time is too short, the breathing score or monitoring data will not be displayed (usually the night sleeping time is more than 3 hours);
3. Inappropriately wearing the bracelet will result in a failure to monitor the breathing score. It is recommended not to wear the band loosely (the band should be one finger's width away from the wrist bone).
4. If the above information does not help, please check whether the APP and the band firmware are the latest version. Meanwhile, it is recommended to restart the band or re-bind the band and try again.

5. Q: How long does the Xiaomi Smart Band 9 take to complete a blood oxygen measurement?
A: The Xiaomi Smart Band 9 takes about 15-60 seconds to complete a blood oxygen measurement.
Please check the reasons for the timeout of measurement:

It is recommended to adjust the back of the band to ensure that it fits snugly around the wrist.

6. Q: What will happen to the sensor indicator at the bottom of the Xiaomi Smart Band 9 during the blood oxygen measurement?
A: The red light and infrared light (not visible to the naked eye) will turn on. If the green light is blinking, it indicates that the band is measuring heart rate.

7. Q: Why is the red light blinking when the Xiaomi Smart Band 9 is not worn at night?
A: 1. If the advanced monitoring function is turned on, the band will automatically measure the blood oxygen after you fall asleep, and the red light of the band will blink. If you are not wearing the band but the red light is blinking, the monitoring function is misdiagnosed. The Xiaomi Smart Band 9 adopts a high-precision PPG heart rate sensor with infrared light, green light, and red light, which greatly improves its monitoring accuracy compared with traditional monitoring. However, when the band is placed in an environment that is more similar to the wrist, the monitoring function will also be misdiagnosed;
2. When the band is not worn, please pay attention to the heart rate light is not covered by objects (common misdetection scenarios: the band is placed in the bag, bed, table, etc.);
3. If you don't wear the band while sleeping, we suggest you turn off the advanced monitoring function, which can greatly save the power of the band.

8. Q: Will the Xiaomi Smart Band 9 alert the abnormal oxygen saturation values when they are at risk?
A: The Xiaomi Smart Band 9 can be set to alert you of low blood oxygen (80%, 85%, 90%). Measurements are for reference only and are not intended for medical reference or diagnosis. Please consult the healthcare provider if you feel unwell.

9. Q: What to do if the oxygen saturation measurement on the Xiaomi Smart Band 9 is very low?
A: 1. Incorrect wearing position. Due to less blood vessel distribution at the wrist, the blood oxygen value is not easy to measure. Please wear the band around your wrist about one finger's width away from your wrist bone;
2. Wearing too loose. Please wear the band tightly (there is a slight sense of urgency and the band does not move when you shake your wrist);
3. Please stretch your arm and open your elbow joint to avoid inaccurate measurements due to poor blood flow caused by squeezed blood vessels;
4. Place your arm on a stable place such as a table for measurement. Keep the screen of the band facing upwards to avoid an unstable signal due to shaking;
5. It is recommended to move the wearing position of the band to ensure that the back of the band fits the wrist. It is recommended to measure again after keeping it still;
6. The latest version has been optimized. Please upgrade to the latest version to further experience this function.

10. Q: Does the Xiaomi Smart Band 9 support the Standing function?
A: Yes. When you turn on the Standing function, when the band detects 50 minutes of inactivity in an hour, it will vibrate and remind you to be active at the 50th minute. If the band recognizes standing and walking within 10 minutes, it will pop up a "done standing" reminder.
Being sedentary can lead to many health problems. It is recommended that you get up and move around every hour while wearing the band. Standing is a convenient way to increase energy consumption. This function can only be activated from the App, as well as setting the start/end time and lunch break distraction (Path: [Mi Fitness] APP >> [Device] >> [Standing] >> turn on [Remind to stand up] >> set the time period).

11. Q: Why does the standing reminder pop up on the Xiaomi Smart Band 9 even when standing all the time?
A: The standing reminder is designed to keep you active. The band needs to detect wrist activity and step count to determine whether the standing activity behavior is achieved or not. Therefore, if you have been standing still or making small movements, you will also receive a standing reminder. At the same time, we are constantly optimizing the algorithms related to standing determination to gradually improve the user experience.

12. Q: Why does the standing reminder suddenly pop up on the Xiaomi Smart Band 9 when just started the activity?
A: Certain conditions are required to determine the standing reminder. If you receive a standing reminder from the band just after you start your activity, it is because you are in an active state but have not reached the threshold of standing behavior. You can continue to move and ignore the alert. If this phenomenon occurs frequently, you can submit user feedback on the Mi Fitness APP. We are constantly optimizing the algorithms related to standing determination to gradually improve the user experience.

A: The latest version (1.1.122) has optimized the logic of the pop-up window when the vitality score reaches the target. The pop-up will only appear when the accumulated vitality score has increased from below the value of 30, 60, and 100 to equal to or above the value of 30, 60, and 100 in the last 7 days. Please upgrade the band to the latest version to experience this feature.

15. Q: Why is today's vitality score lower than yesterday's on the Xiaomi Smart Band 9?
A: The vitality score of the Xiaomi Smart Band 9 is personalized based on the data of the last 7 days. At 0:00 every day, the vitality score gained 7 days ago will be considered invalid. Therefore, you will find that your vitality score is lower than that of yesterday. You need to keep gaining a vitality score to maintain your vitality score.

16. Q: Does the Xiaomi Smart Band 9 support connecting to a body fat scale?
A: No.

17. Q: Under what conditions is the heart rate sensor on Xiaomi Smart Band 9 enabled?
