How Sleep Detection Works

Sleep detection determines whether you are asleep based on changes in your state after you put on the earbuds, then generates sleep data in the app. Because sleep habits and wearing conditions vary from person to person, the results may not always be completely accurate.

Sleep detection primarily relies on the motion sensor in the earbuds. If you remain still for a long time while awake, or leave the earbuds on a desk or another surface, they may incorrectly detect that you have fallen asleep.

What to Do if There Is No Sleep Report Data

If no sleep data appears, try the following:

1. Reconnect the earbuds: connect the earbuds to the soundcore app to sync the latest sleep data.

2. Keep your earbuds connected regularly: you do not need to open the app every night before bed to sync the time. However, we recommend connecting the earbuds to the app at least once a week to sync data.

3. Restart the app: if the sleep data still does not sync, restart the soundcore app and try again.

Note: Anker soundcore Sleep Earbuds 4 primarily uses its built-in motion sensor to detect sleep. Compared with smartwatches that use multiple sensors, such as heart-rate sensors, sleep detection may be less accurate.
