A missing sleep report does not necessarily mean your smart ring is broken. First make sure the ring has charge and can sync with its app; then check whether the app is hiding a report or the ring did not detect enough sleep to create one. Work through the checks below in order, using your manufacturer’s instructions for model-specific resets.
1. Check whether the sleep report is delayed or hidden
Turn on Bluetooth, bring your phone close to the ring, and open the ring’s companion app. Give the sync time to finish, then allow a few more minutes for processing. RingConn says processing can take additional time after synchronization. Check the dedicated Sleep view and its graph as well as the app’s home-screen summary; a missing summary is not proof that no data was recorded.
If the ring has not synced for several days, sync it as soon as possible. Oura says data stored on the ring is temporary and may be lost if the ring powers off before syncing. Its Member Care page, last updated October 1, 2026, puts it plainly: “If your Oura Ring isn’t synced with the Oura App for several days, collected data may be lost.”
2. Check the battery and charger
- Confirm the charger is connected to power and the app or charger indicates that the ring is charging. If it does not, reseat the ring and check the charging contacts for dirt or obstruction.
- For Oura, charge the ring to at least 30% before bed. Oura says low overnight battery can leave sleep analysis incomplete; if the ring fully depletes and powers off, that night’s data may be lost.
- If you suspect the charger itself has failed, use a charger made for your exact ring model and generation. Smart-ring chargers are not universal.
RingConn’s instructions for the Gen 2 Air are model-specific: wipe the contacts with a clean, dry cloth, charge for 30–60 minutes, then follow RingConn’s restart steps. Do not use that restart sequence—or another brand’s charger reset—on a different ring.

3. Check fit and sleep-detection conditions
Confirm that you wore the ring overnight and that it stayed in good contact with your finger. A ring that is too loose, rotates, or loses sensor contact may not collect usable readings. It should fit securely without restricting circulation.
Sleep detection also depends on the ring’s algorithm and the night’s conditions. Oura says its main sleep-cycle detection requires at least three hours of sleep-stage detection within its 6 PM-to-6 PM window. Short sleep, restless sleep, or substantial movement can prevent enough sleep-stage data from being detected. This is Oura-specific guidance, not a universal threshold for every smart ring.
4. Check the app, phone software, and permissions
- Update the companion app and your phone’s operating system, then open the app with Bluetooth enabled and the ring nearby.
- In your phone settings, confirm Bluetooth access and the app’s required permissions. On Android, Oura notes that requirements can vary by Android version, including Location or Nearby Devices access. RingConn also calls out Nearby Devices permission.
- On Android, check whether battery optimization or background-app limits are preventing the companion app from running or syncing. Setting names differ by phone maker and operating-system version.
- Restart the phone, reopen the companion app, and attempt a sync again.
Permission labels and requirements vary across Android versions and manufacturers. Follow the prompts and support instructions for your app, phone, and ring model rather than assuming one settings path applies to everyone.

5. Reset the connection only after basic checks
If the ring still will not connect, use the connection-repair steps published for your exact model. A reset or re-pairing flow can remove a stale Bluetooth connection, but the sequences differ by manufacturer.
Oura
Use Oura’s connection troubleshooting flow for its documented Bluetooth reset, hardware reset, restart, or reinstall options. Do not apply Oura’s charger-based reset steps to another brand.
RingConn Gen 2 Air
RingConn’s documented flow includes forgetting the ring’s Bluetooth device in phone settings, toggling Bluetooth off and on in those settings, reconnecting through the RingConn app, and updating the ring’s firmware. Follow RingConn’s instructions for the Gen 2 Air specifically; do not assume the same steps apply to another RingConn model.

6. Check for a current software issue, then contact support
Before treating missing sleep as hardware failure, check the manufacturer’s current known-issues page. As of October 7, 2026, Oura listed Issue 3096 as open: some iOS users on app version 7.20.0 or newer may not see sleep stages or the sleep graph on Ring 4 or Ring 5 even when the sleep meets detection requirements. Known-issue status and affected app versions can change, so check Oura’s page for the latest status.
Contact the manufacturer if the ring will not charge or connect, or sleep data remains missing for several nights after the normal checks and model-specific reset. Oura says persistent gaps can indicate hardware trouble and notes that, in rare software cases, missing data may not be recoverable.
