Oura Ring Battery Life: How Long It Lasts and How to Check It on iPhone
Oura Ring 5 lasts 6–9 days per charge and Ring 4 lasts 5–8. See battery life by generation, charging time, low battery alerts, and how to check charge on iPhone.
A fully charged Oura Ring 5 typically lasts 6–9 days, Oura Ring 4 lasts 5–8 days, and Gen3 lasts up to seven days. A full charge takes about 20–80 minutes, depending on how low the battery is. Actual battery life varies with ring size, settings, the features you use, and battery age. Oura's battery guide
This guide covers battery life by generation, how to check your ring's charge on iPhone, and how to keep the battery level visible on your Home Screen.
How long does an Oura Ring battery last?
| Typical battery life | Offline storage without syncing | |
|---|---|---|
| Oura Ring 5 | 6–9 days | Up to 3 days |
| Oura Ring 4 | 5–8 days | Up to 7 days |
| Oura Ring Gen3 | Up to 7 days | — |
Ring 5 is 40% smaller than Ring 4 but still lasts slightly longer, because Oura rebuilt its battery system. It also has an optional Charging Case, sold separately: a pocket-sized aluminum case that provides up to a month of battery and charges the ring wirelessly when you are away from an outlet. Introducing Oura Ring 5
These ranges apply to new rings. Like any rechargeable battery, an Oura Ring's battery holds less charge as it ages. If you are deciding between generations, our Oura Ring 5 vs Ring 4 comparison covers battery alongside size and price.
How to check your Oura Ring battery on iPhone
- In the Oura app: tap the battery icon in the upper-right corner of the Today tab to see the current level.
- With low battery notifications: open the menu, choose Settings → Notifications, and turn on battery level notifications. They do not appear while the ring is in Airplane Mode.
- With Oura's widgets: the large Oura Sleep widget and Oura's Lock Screen widgets can show battery. Oura's widget guide
- With Ring Widget: a small battery indicator on the Readiness, Sleep, Activity, and other widgets you already use, described below.
See ring battery next to your Oura scores
Your Readiness score may look great, but it is less useful if your ring runs out of charge before bedtime. Ring Widget can show your Oura Ring battery status beside the health data you already keep on your iPhone Home Screen. The indicator is free.
Example Readiness widget with the ring battery indicator in the top-right corner.
The small ring icon fills according to the latest battery level available from Oura. It appears on supported small and medium Home Screen widgets, including Readiness, Sleep, Activity, and other health views. A charging symbol appears when Oura has recently reported that the ring is charging. The indicator changes color when the battery is low and shows an alert symbol when it is very low.
The icon is meant for a quick glance; it does not print a percentage on the widget. For an exact reading, check the battery level in the Oura app. If a recent battery reading is unavailable, Ring Widget shows a dashed ring instead of implying a current level.
How to turn on the battery indicator
- Update Ring Widget, then open the Oura app and let your ring sync.
- Open Ring Widget. If you see Enable ring battery status, tap Reconnect Oura and complete Oura's authorization screen. Existing connections may need this step to grant access to battery data.
- Add a Ring Widget Home Screen widget if you do not have one yet. Our iPhone widget setup guide walks through the steps.
- To change the setting on an existing widget, touch and hold it, choose Edit Widget, and check Show Ring Battery. The setting is on by default for supported widgets.
The battery indicator is part of the widget layout, so you can keep your Sleep or Readiness view while adding a quick charge check. It does not appear on Ring Widget's Lock Screen widgets or Apple Watch complications.
If the battery looks old or is missing
Ring Widget reads the latest battery sample synced to Oura; it does not connect directly to your ring. Open the Oura app and wait for the ring to sync, then open Ring Widget and give iOS time to refresh the Home Screen. Oura's widget guide also explains that its widgets show data from the last ring sync.
If the indicator is missing entirely, check Show Ring Battery in the widget settings and look for a reconnect prompt in Ring Widget. A dashed ring means battery data is temporarily unavailable. If your other metrics are also stale, use our widget troubleshooting guide to narrow down the cause.
How to make an Oura Ring charge last longer
Oura's battery guide suggests a few simple habits:
- Keep the firmware up to date. Updates need Bluetooth on and more than 30% battery.
- Top up often. Short charges while you shower or sit at a desk prevent the battery from running out overnight.
- Use Airplane Mode when you do not need the ring to sync for a while.
- Pair with one phone only to avoid repeated connection attempts.
If your ring suddenly drains much faster than usual, contact Oura Member Care.
One less thing to remember
Battery status can sit next to the Oura insight you check most often. Download Ring Widget to add it to your Home Screen. The battery indicator and the Readiness and Sleep widgets are free; other layouts require a purchase.
