Troubleshooting Missing Sleep Data or Seeing Gaps in Graphs

Missing Sleep Data? 

If your ring battery level is too low when you go to sleep, your ring will automatically go to power saving mode during the night to protect the ring from battery exhaustion. When this happens, you'll see your bedtime and wake-up time, but you won't get a detailed breakdown of your sleep quality for the night.

  • If you have the new Oura ring, we recommend that the ring's battery level is at least 20% when going to bed.
  • If you have the first Oura ring, we recommended that the ring's battery level is at least 50% when going to bed.

Tips for optimizing ring battery life

  • - Enabling battery level notifications in your app settings will allow your Oura app to remind you when the ring needs to be charged.
  • - Instead of partial charging (from e.g. 30% to 70%), charge the ring until the battery is full whenever possible. If you have the first Oura ring, you can charge the ring daily for 10-15 minutes until the battery is full, instead of every 2-3 days.
  • - A loose-fitting ring has to work extra hard to get a good signal, leading to increased battery consumption. Make sure that the ring fits snugly, without being too tight. If the ring's battery consumption feels high, try if wearing the ring in a different finger makes a difference.
  • - Battery consumption can also increase if the LED bumps inside the ring are dirty. If your ring seems to consume more battery than usual, washing the ring carefully from the inside can help.

 

Seeing Gaps in Your HRV or Heart Rate Graphs? 

Sometimes you can spot gaps in the resting heart rate or heart rate variability (HRV) graphs. Usually this means that something has interfered with your pulse signal tracking, and the ring hasn’t been able to detect your heart rate properly.

Here are the most common reasons for it: 

  1. The ring is too loose and rotates around your finger easily, which means that its LED sensors aren’t positioned optimally for tracking. Or the ring is so loose that the sensors don’t have a good quality contact with your skin. Before going to bed, check that the LED sensors are underneath your finger, and the ring sits snugly enough. If the ring feels too loose, try wearing it on a different finger. Note: make sure that the ring doesn’t feel too tight, either.
  2.  The LED sensors are dirty. You can wash the sensors and the whole ring with water and mild soap. Rinse and dry the ring thoroughly with a soft cloth.
  3.  The ring detects a lot of movement, which temporarily disturbs pulse signal tracking. This can also happen if you’re awake during the night and move around.
  4.  You sleep in a position where your hand goes numb (causing partially blocked blood circulation).
  5.  Your resting heart rate is exceptionally low (below 33 bpm).
  6.  There are interferences in tracking due to arrhythmia. It’s worth noting that gaps don’t usually mean that you would suffer from an arrhythmia, and you can’t use the graph data to diagnose medical conditions.

Please make sure that your Oura app and your ring's firmware are updated to the latest versions.

Here’s how the gaps can look like in the app:
