More Information
Oura Ring 4: A fully charged ring may last up to eight days.
Oura Ring Generation 3: A fully charged ring may last up to seven days.
Battery life and longevity depend on Oura Ring size, Oura App settings, feature configuration, activity, battery age, usage, and many other factors; actual results will vary. Battery life and charge cycles vary by use and settings. Battery tests were conducted across various sizes and scenarios. See Ring Battery tips for more information.
Oura Ring 4 battery estimates are based on consumption data of internal users, analyzing usage from 100% to 0% battery levels. Oura Ring Generation 3 battery estimates were used as a reference to validate any improvements.
Your Oura Ring can take 20-80 minutes to fully charge, depending on its current battery level. You can check the battery level by tapping the battery icon in the upper-right corner of the home screen.
Update Your Ring's Firmware
To ensure the latest firmware version is available, first update the Oura App to the newest version available in the app store on your device.
Starting with version 2.9.11, Gen3 firmware will update automatically.
Note: for the firmware update to succeed, your phone’s Bluetooth must be enabled and your ring’s battery level must be above 30%.
Once you've updated your ring's firmware, go through two charge cycles with your ring. A charge cycle is when you charge the ring to 100% and then allow the battery to deplete to about 25%.
After each charge cycle, back up your ring data by doing the following:
1. Place your Oura Ring on the charger for a few minutes
2. Open the Oura App and wait for the latest sync. If the sync doesn't happen, you can still proceed with the backup
3. Tap the menu in the upper-left corner of the home screen
4. Tap Settings
5. Under Account, tap Back up all data
Charge Your Ring Before Going to Bed
We recommend charging your ring to at least 30% before going to bed. If your ring's battery level is low, you may not receive sleep insights for the night.
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.
Having your charger on-hand (such as in your purse, car, backpack, or at your desk) can help you get into a routine of charging your ring for a little bit each day. Consider charging your ring during natural periods of low activity, such as when washing dishes, typing on your computer, showering, cooking, etc.
Enable Airplane Mode
If you’re looking to get the most out of each charge, we suggest placing your ring in Airplane Mode. This turns off all Bluetooth communication between your ring and phone, which can help to conserve battery.
Enable Low Battery Notifications
To receive reminders before bed when your Oura Ring battery is low, enable battery level notifications in the Oura App.
- Go to the menu
in the upper left-hand corner of the home screen
- Tap Settings > Notifications
- Enable battery level notifications
Note: notifications will not appear if your ring is in Airplane Mode.
Prevent Damage to Your Battery
The USB charging power cord is intended to be supplied by an external 5Vdc supply that complies with EN 62368-1 standard.
Other factors may also lead to battery damage:
- Leaving your ring on the charger for a period of time greater than one week. Charging for extended periods of time while at maximum capacity can negatively affect battery life
- Long exposure to extreme temperatures (-20–60 ºC / -4–140 ºF)
Properly Store Your Ring
If you plan on taking a break from wearing your ring (for more than two weeks), we recommend charging your ring above 50% and then placing your ring in Power Saving Mode before storing it.
Only Use Your Ring with One Device
The intended use and setup of an Oura Ring should consist of the following: one ring, one account, one device. If there are multiple users or data sources feeding into the same account, this leads to missing data, connectivity issues, or even accelerated battery consumption.
