iOS Power Scheduling

iOS workers can contribute in swarm mode with power-aware scheduling controls. This page summarizes telemetry fields and coordinator-side policy expectations.

Why power-aware scheduling exists

• Prevent draining participant devices.
• Prefer assignments when device power conditions are healthy.
• Maintain reliability for long-running tasks.

Telemetry inputs

Signal	Meaning
IOS_ON_EXTERNAL_POWER	device is charging/external power connected
IOS_BATTERY_LEVEL_PCT	battery percentage reported by worker
IOS_LOW_POWER_MODE	iOS low power mode state

Policy controls

Variable	Purpose
IOS_BATTERY_PULL_MIN_INTERVAL_MS	throttle between assignment attempts on battery
IOS_BATTERY_TASK_STOP_LEVEL_PCT	minimum battery level before stopping assignment

Assignment decision sketch

Operator practices

• Keep iOS fleet policy conservative by default.
• Track assignment drop reasons to understand power-policy impact.
• Use separate worker pools if mobile and desktop reliability goals diverge.
