The Xiaomi Smart Band 9 Pro can store data independently. Some functions of daily activities can be used independently. Only the band needs to be connected to the phone when synchronizing data with the Mi Fitness APP. The band can store up to about 100 hours of recorded exercise data, display 20 exercise records, and store up to 7 days of vitality data and health data such as sleep, heart rate, blood oxygen, and stress. The band can only display the data of the day.
The data that has been synchronized to the APP will be automatically uploaded to the cloud storage. You can go to the [Mi Fitness] APP >> [Profile] >> [App settings] >> [Sync with the cloud] >> enable [Sync with the cloud]. If you change to a new phone, you can use the previous Xiaomi Account on the new phone to bind with the band, and the previous data can be synchronized from the cloud to the new phone.
Note:
With the size of the exercise record, the number of saved entries will change. Please refer to the actual situation.
