Estimated Battery Life by Usage
Based on 45Wh capacity with conservative estimates for typical Fujitsu laptop usage:
| Usage Scenario | Estimated Runtime | Power Settings |
|---|---|---|
| Web Browsing | 3-4 hours | Balanced, medium brightness |
| Document Editing | 4-5 hours | Power saver, low brightness |
| Video Streaming | 2-3 hours | High performance, medium brightness |

Note: These are conservative estimates for a new battery. Actual runtime may vary based on your specific laptop model, age of other components, software efficiency, and power settings. New replacement batteries may provide shorter runtime compared to the original battery when your laptop was brand new due to increased software demands and natural hardware aging.
