Charging Your Ring & Best Practices
Please be sure to order the correct charger size relative to the ring size you currently own. To check your ring size, look on the inside of your Oura Ring (listed next to the QR code), or tap the battery icon in the upper right-hand corner of the Oura Home tab and swipe left.
Charging Your Ring
Your Oura Ring can take anywhere from 20-80 minutes to charge, depending on your battery level. Check your battery level by tapping the ring in the upper right-hand corner of the Home tab.
To charge your ring, connect the USB cord to the charger and plug the USB into a power source (e.g., a laptop, or power brick). Then, place your ring on the charging dock. The LED light on the charger will begin pulsing after you've set the ring on the dock. When the light stops pulsing, your ring is fully charged. You will receive a push notification when charging is complete.
If the LED light doesn't light up, ensure the charger's cable is properly connected. Double-check that your ring is positioned correctly, ensuring good contact between your ring and the dock.
1. Best Times to Charge Your Ring
Generally, we suggest keeping your charger handy in your purse, car, backpack, or at your desk. Because the charger's USB cord quickly connects to laptops and power bricks, you can charge your ring easily while working, watching television, browsing the internet, or doing the dishes. We recommend keeping your ring's battery level above 40%, if possible.
2. Enable Low Battery Notifications
To receive reminders before bed when your Oura Ring's battery is low, enable Battery level notifications in the Oura App. To do so, follow the steps below.
- Go to the menu in the upper left-hand corner of the Home tab.
- Tap Settings > Notifications.
- Enable Battery level notifications.
3. Ensure Your Ring is Charged Before Bed
It’s important that your ring be charged to at least 25% before going to bed, which is why employing some of the strategies listed above may be beneficial. If your battery level isn't at least 25% prior to bed, you’ll miss out on your Sleep insights for the night.
Keep in mind: if this occurs, you’ll still receive a bedtime and wake-up time, but no Sleep or Readiness Score, and no further breakdown of your sleep stages, heart rate variability, respiratory rate, or resting heart rate. Consider getting into the habit of charging your ring a little bit each day so you’ll never have to miss out on personalized insights from Oura when you wake-up.
Things to Keep in Mind
What to Expect from Your Oura Ring Battery
On average, a fully charged ring will last 4-7 days. This can vary depending on several factors, such as the age of your ring, how often you make use of daytime features, and if you take naps throughout your day. Keep in mind that more battery will be used whenever your ring is actively collecting data from its LED and temperature sensors—for example, while using meditation sessions or Live Heart Rate features.
Keep in mind that batteries are complex, and many variables can contribute to battery life and longevity. All rechargeable batteries are consumables and have a limited lifespan, so their capacity and performance will gradually decline with time.

Prevent Damage to Your Battery
Certain factors may lead to battery damage. They are listed below.
- Leaving your ring on the charger for a period of time greater than one week. Charging while at maximum capacity for extended periods of time can reduce battery life substantially.
- Long exposure to extreme temperatures (hot/freezing).
- Allowing your ring’s battery to reach 0% can affect its longevity.
- The charger's USB power cord is intended to be supplied by an external 5Vdc supply that complies with IEC 62368-1 standard. The power available to the equipment should not exceed 15W after 3 seconds.
