Reference
Adaptive check intervals
| Connection duration | Default interval | Why |
|---|---|---|
| First minute | 5 seconds | Quickly catch state changes |
| 1 to 10 minutes | 10 seconds | Moderate monitoring |
| 10 to 60 minutes | 30 seconds | Stable connection, check less |
| 1 to 10 hours | 10 minutes | Low frequency |
| Over 10 hours | 1 hour | Save battery |
Good to know: Every interval is editable in the inspector, together with the sync retry debounce (60 seconds by default), network warnings and debug logs.
