Usage Example

Basic Integration

import { useMobileCallOptimization } from '@/hooks/use-mobile-call-optimization'
import { MobileCallScreen } from '@/components/calls/mobile/MobileCallScreen'
import { MobilePiPOverlay } from '@/components/calls/mobile/MobilePiPOverlay'

function MobileCallInterface() {
  const {
    initialize,
    cleanup,
    optimizationStatus,
  } = useMobileCallOptimization({
    autoBatteryOptimization: true,
    autoEnablePiP: true,
    lockOrientation: true,
    enableNativeCallUI: true,
    enableVoIPPush: true,
  })

  useEffect(() => {
    initialize()
    return () => cleanup()
  }, [])

  return (
    <>
      <MobileCallScreen isVisible={true} />
      <MobilePiPOverlay isActive={false} />
    </>
  )
}

Performance Characteristics

Battery Impact

  • Audio-only call: ~1-2% per 10 min
  • Video call (720p, 30fps): ~5-8% per 10 min
  • Video call (480p, 24fps): ~3-5% per 10 min
  • Video call (360p, 20fps): ~2-4% per 10 min
  • Battery saving mode: ~1-2% per 10 min

Optimization Thresholds

  • High Quality: 30%+ battery, charging
  • Medium Quality: 20-30% battery
  • Low Quality: 10-20% battery
  • Audio-Only Suggested: <10% battery

Testing Checklist
