In some rare cases the ring battery consumption has been significantly higher than it should, and the battery has run out in less than 1-2 days. We’re currently investigating these cases. If the problem persists, please submit a request to our support team.
To speed up the handling: 

There are situations where Oura may not show your resting heart rate and heart rate variability graphs properly, for example if your resting heart rate is exceptionally low (below 33 bpm) or you have exceptionally high HRV (respiratory sinus arrhythmia, or other arrhythmia). Learn more.

We've been reported by some users that their sleep and readiness data isn't synced to the app, but the app shows activity data for the day. We're investigating this issue, and will release a fix as soon as possible. If you notice that your sleep data isn't synced to the app (either continuously or occasionally), switching your phone's Bluetooth off for the night can help to avoid this issue. 

We’ve discovered cases where the ring firmware update fails. Our team is working on this issue. Meanwhile, if you face problems in updating your ring firmware when the app prompts you to do so, first try restarting your phone. Also a ring factory reset can help (remember to back up your data in the app settings first).

We have seen some cases where the ring reports too much activity. We are currently investigating these cases and working to improve our algorithms. Improved algorithms will be introduced soon.

If you experience Bluetooth connectivity problems, restarting the app and switching Bluetooth off and on in your phone settings helps. In some rare cases you may need to restart your phone.

You can also try the troubleshooting steps as listed here.

Note for Huawei users: 

We've discovered that some Huawei phone models have advanced settings for battery usage optimization for Bluetooth devices, and this has caused connectivity issues. If you're using a Huawei device and your ring doesn't connect to the app, please do the following: 

Go to your phone settings: Battery - Launch - Oura - Manage manually - check all checkboxes.

We have noticed that with some phone models the app might take several minutes to update the sleep analysis. Currently we are aware that the following models may experience this issue:

It’s been reported by some users that the connection between the app and the ring is intermittent. Usually restarting the app or in some cases the phone helps. Currently we are aware that the following models may experience this issue:

This seems to have started after the Android 9 OS update. In some cases clearing Bluetooth cache or resetting mobile device network settings has re-established the connection.

Sorry for the trouble! We are investigating these issues and will release a fix as soon as possible.

There can be minor differences in the data between the Oura app and Oura Cloud (for example body temperature deviation and average heart rate). These differences can be caused by rounding errors or the selected time windows in the app and Cloud.

Also if you have taken a new ring into use it might have an effect on the readings.
