Sleeping data on the Xiaomi Watch 2 refers to the information collected and analyzed by the watch related to your sleep patterns and quality.
If your smartwatch doesn't record sleeping data or the sleeping data is not accurate, please refer to the following troubleshooting steps:
1. Please ensure the Mi Fitness app and the smartwatch's firmware are updated to the latest versions by opening the Mi Fitness app and checking the versions;
2. Ensure that the sleep monitoring feature is not turned off;
3. Please try to temporarily unbind the watch from the app. After rebinding, turn on auxiliary sleep monitoring and see if the problem is improved;
4. If the watch is worn too loosely or shakes significantly, it will cause abnormal sleep monitoring during sleep. It is recommended that you wear your device steadily while sleeping;
5. Please confirm your sleep period. Sleep time that is too short (less than 20 minutes) will result in no sleep data being recorded;
6. If the watch battery is low, it may cause the sleep monitoring function to malfunction or interrupt. Make sure to fully charge the watch before sleeping to ensure it can continuously monitor sleep data throughout the night;
7. If the watch is in a relatively quiet state that is similar to the sleeping scene, the sensor may be judged to be sleeping, resulting in errors in the time to fall asleep;
8. Please restore the watch to the factory setting. All data stored on the watch, including apps, settings, accounts, and any personal files, will be erased.
