Estimated Battery Life by Usage
Based on 45Wh capacity with typical ASUS laptop power consumption:
| Usage Scenario | Estimated Runtime | Power Settings |

| Web Browsing & Documents | 3-4 hours | Power Saver, 50% brightness |
| Video Streaming | 2-3 hours | Balanced, 60% brightness |
| Gaming | 1-1.5 hours | High Performance, max brightness |
| Video Conferencing | 2-2.5 hours | Balanced, camera active |
