How long does the battery last on a charge for an Oura Ring?

The battery life of an Oura Ring on a single charge typically lasts around 4 to 7 days, depending on the usage patterns and the specific activities being tracked. The advanced sensors within the ring continuously monitor various physiological signals such as heart rate, temperature, and movement, which can influence battery drain. However, it is designed to be energy efficient to ensure that users don't need to recharge it too frequently. When the battery does run low, recharging is relatively quick, usually taking about an hour to reach full capacity again, allowing users to promptly get back to tracking their health and activity data.
