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:Due to different mechanisms and standards for access card authentication in the market and varying card permissions managed by property management, 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.

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 does 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

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] >> [Wear mode] >> [Enter the pebble mode] to switch it. On the Mi Fitness APP, you need to tap [Device] >> [Switch wear mode] >> [The 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;4.

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 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 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 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.Sports related1.

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 independent positioning function, the positioning information and trajectory data of the band come from the mobile phone. Therefore, this type of outdoor sports 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]. And 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 is still deviated, 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 come 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 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 the 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 with 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 the 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.System Settings1.

You can try pressing the [Quick-release] button while adapting the strap, and after several detachments and attachments, you will experience a better visual and wearing feel.
