Due to the definition of the dual-end mutual writing synchronization protocol of Mi Fitness App, according to your usage habits, there will be a minimum data difference of 5 minutes and a maximum of 30 minutes after completing automatic synchronization or manual synchronization. For example, after synchronization, If there is a minimum 5-minute data difference, the calories and steps data generated within the 5 minutes will not be reflected until the next synchronization. This setting is currently being interpreted and continuously optimized by Mi Fitness App engineers.
