Oura Ring

Oura Ring Battery Dashboard

Tracking the ring's charge over time - how fast it drains through a day of wear, and how it climbs back up on the charger.

Battery over time

The charge/drain sawtooth, plotted at each reading's actual time - draining through the day, jumping back up on the charger. Hover any point for details.

Battery drain & estimated life

How fast the ring loses charge per hour of wear, over two windows, plus how long a full 100% charge lasts. Measured across draining intervals only, so charges don't skew it.

Estimated battery life
8 days 16 hours

A full charge should last about 8.7 days (~208 hours) at the trailing 7-day rate.

The baseline pools every reading to track overall behavior and long-term degradation, while the recent trailing average captures current battery behavior (like overnight SpO2 drains).

Battery degradation over time

Inferred from how full-charge runtime shrinks as the battery ages, since the Oura API doesn't expose raw battery capacity.

Not enough data yet - need more readings over time

Degradation compares the first 30 days of readings against the most recent 30 days. So far there are about 11 days logged - keep logging and this will fill in.

Readings by day
