Frequently Asked Questions
How accurate is the Oura Ring 4 for sleep tracking?expand_more
In our testing, the Oura Ring 4 provided detailed and generally consistent sleep stage tracking, including REM, deep, and light sleep, alongside heart rate variability. While many users find its insights valuable for understanding sleep patterns and recovery, some comparisons suggest that dedicated fitness bands might offer slightly more granular precision in sleep stage classification. However, its overall readiness score synthesises multiple factors for a holistic view.
What is the battery life of the Oura Ring 4 in real-world use?expand_more
The Oura Ring 4 is advertised to last up to 8 days on a single charge. Our initial testing confirmed battery life typically in the 6-7 day range. However, a significant point of concern raised by numerous users is that battery capacity can degrade noticeably after about two years, with some reporting drastically reduced battery life, making consistent daily use problematic.
Does the Oura Ring 4 require a subscription?expand_more
Yes, the Oura Ring 4 requires an Oura Membership subscription to access the full suite of advanced insights, personalised recommendations, and historical data. Without the subscription, access to detailed analytics, sleep scores, and readiness trends is significantly limited. This ongoing cost is an important factor to consider when evaluating the total cost of ownership.
Is the Oura Ring 4 suitable for intense exercise tracking?expand_more
The Oura Ring 4 is not primarily designed for intense exercise tracking. While it monitors heart rate and activity levels, its accuracy for real-time heart rate during high-intensity workouts can be inconsistent, and it lacks built-in GPS. For users focused on detailed sports performance metrics, more specialised smartwatches or fitness trackers are generally a better choice.
How does Oura Ring 4 sizing compare to Gen 3?expand_more
Users have noted that the Oura Ring 4's flatter sensor design can affect fit compared to the Gen 3. A size that felt snug on a Gen 3 might feel looser on the Gen 4 due to this design change. Therefore, we strongly recommend utilising the Oura sizing kit before purchasing to ensure an accurate and comfortable fit for the Gen 4 model.
Why do users report battery life dropping significantly after two years?expand_more
While the exact cause isn't always specified, user reports consistently indicate a significant drop in battery capacity for Oura Rings (including Gen 3 and potentially Gen 4) after approximately two years. This could be due to natural battery degradation over time, software updates impacting power consumption, or the cumulative effect of daily charging cycles on the internal battery technology.
