What to Expect from Your Oura Ring Battery

A fully charged Oura Ring should last up to 7 days. However, the actual running time of the device would depend on the ring itself. Factors such as the age of your ring, how often you make use of daytime features, and if you take naps throughout your day will determine how long the battery would last.

How to Prevent Damage to Your Battery

To prevent damage to your Oura Ring battery, you should follow the steps below

  • Avoid leaving your ring on the charger for a period of time greater than one week. Charging your Oura ring while at maximum capacity for extended periods of time could reduce battery life substantially.
  • Avoid exposing the Oura Ring to extreme temperatures (hot/freezing). Leaving this for long periods could damage the battery.
  • Allowing your ring’s battery to reach 0% can affect its longevity and cause its performance to decline faster.
  • The charger’s USB power cord should be supplied by an external 5Vdc supply that complies with IEC 62368-1 standard. The power you make available to the equipment should not exceed 15W after 3 seconds.

How to Care for Your Oura Ring 

Clean Your Sensors

You should clean the infrared LED sensors (which are the three small bumps) located on the interior of your Oura Ring. This should be done at least once a week. To wipe them down, you should use the inside of your t-shirt or a piece of cloth or by rinsing your ring with a small amount of mild dish soap and water.

This should easily remove any dust or dirt that could interfere with the signal between your ring’s sensors and the arteries on the palm side of your finger.

Avoid Extended Exposure to Extreme Temperatures

The Oura Ring isn’t built for extreme temperatures and this could damage the device as well as your battery. The Oura’s operating temperature ranges from 14°F – 129°F / -(10)°C – 54°C.

This allows you to safely wear your ring in hot tubs, saunas, ice baths, and cryotherapy tanks. While won’t pose a problem, leaving the Oura exposed to extreme temperatures for extensive periods (below 32°F / 0°C or above 95°F / 35°C) may lead to battery damage.

Tips for Scratch Prevention

With continuous use, all Oura Ring colors, models, and styles will develop scratches. Scratches or other damage caused by wear and tear could be problematic and reduce the performance or longevity of the ring. 

To prevent scratches and damage, you need to; 

  • Wear your Oura Ring on your non-dominant hand as this will reduce the amount of contact with various surfaces and objects you interact with on a daily basis
  • You should also avoid wearing other rings adjacent to your Oura Ring. These rings could scratch your Oura Ring while rubbing against it
  • In situations involving friction, you should consider removing your Oura Ring. You should also avoid doing so when handling objects made of metal, ceramics, or stone such as handling pots or pans.
