Expected Battery Life
Based on 41.5Wh capacity with typical usage patterns:
| Usage Scenario | Estimated Runtime | Notes |
|---|---|---|
| Web browsing | 3-4 hours | Multiple tabs, Wi-Fi on |
| Document editing | 4-5 hours | Word processing, spreadsheets |
| Video streaming | 2.5-3.5 hours | HD video, medium brightness |

| Idle/standby | 6-8 hours | Screen off, background apps |
Note: These estimates are conservative. Actual battery life may vary based on your specific laptop model, age, screen brightness, and running applications. New batteries in older machines typically provide shorter runtime compared to when the laptop was new due to increased software demands and hardware aging.
