1. The connection between the watch and the APP is disconnected, and the number of steps is not synchronized in time. The Mi Fitness APP can be synchronized after being refreshed again;
2. In addition, when the watch synchronizes data with the mobile phone APP, the device receives the data value transmitted by the APP to be discarded when it is less than the local value of the device (the device data is not covered), and when it is greater than the local data of the device, the transmitted data is used. Synchronize to the local, and continue to accumulate after the current hour is synchronized (there will be a 30-minute delay in data synchronization), which is also one of the reasons for this phenomenon.
