One of the big selling points of the Oura Ring 4 is its improved battery life compared to earlier generations. But exactly how long does it last? Whether you’re a prospective buyer or a current user wondering about real-world endurance, understanding the ring’s battery performance is key. In this post, we’ll dive into what Oura claims, what affects the battery life, and how you can get the most out of each charge.
What Does Oura Claim About the Ring 4 Battery Life?
- According to Oura’s official support pages, a fully charged Oura Ring 4 typically lasts between 5–8 days.
- Charging time is relatively quick: 20–80 minutes, depending on how much battery is left when you start charging.
- In controlled battery-life tests, Oura assumed typical usage: one hour of Automatic Activity Detection (AAD) per day, eight hours of sleep, and SpO₂ (blood oxygen) monitoring turned off.
What Affects Real-World Battery Life
While 5–8 days is Oura’s stated range, many real-world factors can change how long the ring lasts:
- Ring Size
- Larger ring sizes house slightly bigger batteries, which may last longer.
- Feature Usage
- Battery Age & Usage
- Settings & Syncing
- Sync frequency, Bluetooth usage, and other app settings can also affect power consumption.
Real-World Reports: What Users Are Saying
- Some users report 5–6 days of use on a full charge when all features are enabled.
- According to Android Police, smaller ring sizes (like size 4 or 5) may not reach the full 8-day claim; larger sizes perform better.
- From user discussions on Reddit:
“Mine is 5-6 days with everything turned on …” Reddit
But some report much shorter battery life over time:
“After 6 months … I’ve been lucky to get 3 days of charge …” Reddit
Tips to Maximize the Battery Life
Here are some actionable ways to prolong your Oura Ring 4’s battery life:
- Charge strategically: Drop it on the charger during downtime (e.g., while showering or getting ready) rather than waiting for it to fully deplete. Oura Support
- Turn off SpO₂ if not needed: If your blood oxygen levels are already stable, turning this off can save a lot of battery.
- Limit high-heart-rate tracking: Use AAD and avoid long continuous sessions unless needed.
- Use Airplane Mode occasionally: According to Oura, this can help save battery when you don’t need to sync. Healthline
- Maintain room-temperature charging: Charging in recommended temperature ranges helps battery health. Oura Support
Conclusion: Is the Oura Ring 4 Battery Life Good Enough?
Yes — 5–8 days of battery life is solid for a smart ring, especially given the number of continuous sensors it runs. While some feature-rich use cases or smaller ring sizes may bring that closer to the lower end, most users will find it very manageable.
If battery longevity is a big concern for you, optimize your settings (SpO₂, heart rate) and use smart charging habits. Even partial daily top-ups can keep the ring powered without much hassle.👉 Tip: Monitor your battery over a few charge cycles to understand your personal usage pattern. That way, you can adapt charging habits to your lifestyle.
