Limitations

Apple enforces system budgets for Live Activities to preserve battery life and device performance. These limits are not officially documented and are dynamically adjusted based on factors such as battery level, thermal state, and Low Power Mode status.

The following thresholds have been identified from device logs. Note that these are estimates and may vary across iOS versions:

• Started activity limit: A budget of 10 started Live Activities within a rolling window. In testing, we’ve seen the budget replenish by 1 every 15 minutes (on a fully charged device), but expect this to vary.
• Updates per activity: Up to 240 high-priority updates per activity. Aivi currently sends all updates as high priority to ensure timely delivery.
