The Oura Ring 4 is widely praised for its sleek design and comprehensive health tracking. However — like any wearable — it’s not perfect. Many users and reviewers asking what are some common Oura Ring 4 problems have highlighted recurring issues, including battery and charging problems, data inaccuracies, app glitches, durability concerns, and limitations in activity tracking. It’s important to understand these potential drawbacks before you buy or rely on your ring’s readings.
Common Problems & Issues Reported with Oura Ring 4
1. Battery & Charging Issues
- Many users report rapid battery drain — some say their ring lasts only 1–2 days instead of the advertised 5–8 days.
- Others describe rings that stop charging properly or fail to hold a charge after a few months. > “stopped charging … the charging station light turns white for a few seconds and then fades out.”
- Several accounts mention having to replace their ring under warranty — sometimes more than once. > “I’ve been on my third Oura 4 ring in less than a year.”
- According to the manufacturer’s own support site, there have been firmware-based issues where some rings wouldn’t charge to 100%.
These problems undermine reliability — a smart ring loses much of its value if it can’t stay charged or loses battery health quickly.
2. Data Gaps, Sleep-Tracking Failures & Accuracy Limitations
- When the ring’s battery is low overnight, it may enter a low-power mode — leading to missing or incomplete sleep data (e.g. no heart-rate or sleep-stage detection).
- The ring sometimes misclassifies inactivity as sleep — for instance: long periods of sitting (reading, watching TV) might be recorded as sleep.
- Users who move a lot during sleep (restless sleepers) report the ring fails to detect proper sleep stages or misses data.
- The ring’s activity and workout tracking are less precise compared to a dedicated smartwatch or fitness tracker — especially for activities involving minimal finger movement (e.g. cycling, weight lifting, yoga).
the ring is more reliable for general sleep / rest / lifestyle tracking than for highly precise or clinical-grade data.
3. App, Connectivity & Sync Issues
- Some users report the ring fails to connect via Bluetooth or the app after a sleep cycle — meaning data doesn’t sync correctly.
- There have been documented firmware/app-related bugs: e.g. some Android users experienced repeated onboarding loops, charger-LED glitches, or battery-charging issues.
- For some, data seems to get lost if the ring isn’t synced frequently — or if the ring loses power before syncing.
4. Durability & Long-Term Reliability Concerns
- En ring’s battery is non-replaceable — meaning over time, battery degradation may permanently affect functionality.
- Some users report hardware failures (ring becoming “dead”, charger problems) after a few months.
- Because it’s a small wearable with delicate internals, everyday wear-and-tear (water exposure, knocks, pressing against surfaces) may affect sensors or the charging port.
5. Limited Fitness Tracking & Lack of Advanced Features Compared to Smartwatches
- En ring does not include GPS, so outdoor runs, cycling, or route tracking won’t be recorded accurately.
- It may over- or under-estimate step counts or calorie burn, especially during complex activities (static exercise, strength training, or movements that don’t involve finger motion).
- For serious athletes or users needing detailed workout analytics (pace, elevation, splits, real-time data), a smartwatch or dedicated fitness tracker remains more appropriate.
What Some Users Say (Real Stories & Experiences)
“It once stopped tracking my sleep — then would not connect via Bluetooth or charge. Now it feels completely dead.”
“After about 6 months I started needing to charge it every 2–3 days — then I had to replace it. Now I’m on my third one in under a year.”
“Ring battery drops 25% overnight, though I charged to full. Doesn’t even get through a full night of sleep tracking.”
These firsthand complaints show that while many owners enjoy Oura Ring 4 for months without major issues, a non-negligible subset faces frustration — especially with battery longevity, reliability, or hardware defects.
What Oura (Officially) Says — Known Issues & Warnings
- On their support page, Oura says low night-time battery causes gaps in sleep data, and recommends charging to at least 30% before bed to avoid missing sleep metrics.
- They acknowledge various past firmware/app problems — e.g. battery not charging to full, charger light malfunction, connectivity issues with certain Android devices.
- Also, because the battery is sealed and non-replaceable, once its capacity degrades, you may need to replace the entire ring.
Who Might Be More Affected by These Problems
The issues tend to be more noticeable for people who:
- Sleep poorly, move a lot at night, or change fingers often (for ring wear) — because sleep tracking and sensor contact may be compromised.
- Depend heavily on continuous metrics (e.g. daily readiness, recovery, precise HRV) — battery glitches or sync failures can lead to missing or misleading data.
- Use the ring for exercise tracking — without GPS or accurate motion detection, certain workouts won’t be tracked well.
- Expect long-term device life — battery degradation or hardware failure means the ring might not last as long as traditional jewelry.
Balance: Despite Problems, Many Users Still Find Value
It’s not all negative: many reviews praise the ring’s comfort, its improved sensor design, solid sleep-tracking in normal conditions, and the convenience of a ring form factor rather than a bulky watch.
For many, Oura Ring 4 delivers valuable insights into sleep, recovery, stress, and basic health — as long as they understand its limitations and are willing to monitor battery and data quality closely.
Tips to Mitigate / Avoid Common Problems
- Charge regularly — before bed: Ensure battery is >30% to avoid overnight sleep-data gaps.
- Sync daily: Don’t wait too long — syncing frequently reduces risk of data loss if ring powers off.
- Use latest firmware/app: Updates may address bugs related to charging, Bluetooth, sync, and data tracking.
- Wear snugly & correctly: Proper fit ensures sensors stay in contact — avoid very loose or overly tight sizing.
- Use ring + smartwatch combo (if needed): For workouts or GPS-based tracking, a watch may be more reliable than the ring.
- Know warranty terms: Because battery isn’t replaceable, rely on warranty or plan for replacement if battery degrades.
Conclusion: Oura Ring 4 Has Great Potential — But It’s Not Without Flaws
En Anillo Oura 4 remains one of the most capable smart rings available, offering compelling sleep, wellness, and lifestyle tracking in a subtle, wearable form. That said — especially based on real-world user reports — it does have notable drawbacks. Battery drain, charging failures, data gaps, and limitations with activity/workout tracking are recurring issues for some users.If you decide to get one, go in with realistic expectations: treat the ring as a wellness companion — not a medical device or perfect smartwatch. And if you’re relying on it heavily for data, commit to regular charging, syncing, and hardware care to maximize reliability.
