Battery Basics
Typical Battery Life
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.

Charging Time
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.
Tips to Maximize Battery Life
1. Update Your Ring's Firmware
Firmware updates can include improvements to battery performance. To make sure your ring is running the latest version, 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
2. Charge Your Ring More Often
Feel free to drop your ring on the charger for short bursts more frequently (e.g., when you take a shower each day). Not only will this not damage the battery, but Oura’s lithium polymer batteries actually perform the best when they’re at 25-80%.
A simple way to build a routine is to charge Oura Ring during moments of low activity — like while cooking, showering, or working at your desk. Keeping a charger nearby (in a bag, at your desk, or at home) can make quick, regular charging easier.
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.
3. Enable Low Battery Notifications
You can get reminders when your battery is low by turning on battery level notifications in the Oura App.
- Tap the
menu in the upper left-hand corner of the Today tab
- Go to Settings > Notifications
- Enable battery level notifications
Note: notifications will not appear if your ring is in Airplane Mode.
4. Use Airplane Mode
Turning on Airplane Mode temporarily stops Bluetooth communication between Oura Ring and your phone. This can help reduce battery use when you’re not actively using the app.
5. Use Your Ring with One Device Only
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.
Avoid Battery Damage
The USB charging power cord is intended to be supplied by an external 5Vdc supply that complies with EN 62368-1 standard.
To help maintain long-term battery health:
- Don’t leave your Oura Ring on the charger for more than a week
- Try not to charge for extended periods when the battery is already full
- Avoid exposing your Oura Ring to extreme temperatures (below -20°C / -4°F or above 60°C / 140°F), especially for prolonged time
If You're Storing 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.
