Galaxy Watch 6 Sleep Tracking Not Working: Fix
If your Galaxy Watch 6 isn't tracking sleep properly, these solutions address the most common issues.
Sleep Data Not Recording
Enable auto sleep detection:
On watch: Settings Apps Samsung Health Sleep Enable Detect sleep automatically
On phone: Samsung Health Sleep Settings Enable Track sleep automatically
Other checks:
- Battery must be above 30% before sleep
- Wear watch snugly (sensor must contact skin)
- Set sleep schedule in Samsung Health
Sleep Stages Not Showing
- Enable blood oxygen during sleep (required for stages)
- Wear watch entire sleep period (4+ hours minimum)
- Enable continuous heart rate monitoring
- Wait 30-60 minutes after waking for processing
Sleep Animals Not Appearing
- Requires 14 consecutive days of sleep data
- Each night needs complete data (stages, SpO2)
- View in Samsung Health app, not on watch
- Update Samsung Health to latest version
Inaccurate Sleep Data
- Calibrate by wearing for 7-14 consecutive nights
- Clean HR sensor with microfiber cloth
- Ensure firm sensor contact (no gaps)
- Update watch software
Quick Troubleshooting
| Issue | Solution |
|---|---|
| Not recording | Enable auto-detect, charge above 30% |
| No stages | Enable SpO2, wear all night |
| Inaccurate | Clean sensor, snug fit |
| No coaching | Wait 14 days, update app |
Sensor Check
If sleep tracking consistently fails:
- Test heart rate manually (Samsung Health Heart rate)
- Test SpO2 manually
- If both fail, contact Samsung support
Best Practice
Pre-sleep checklist: Watch charged to 50%+, auto-detect enabled, blood oxygen monitoring enabled, watch worn snugly on wrist.
