Estimated Battery Life by Usage
Based on 42Wh capacity with conservative estimates:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 4-6 hours |
| Word Processing | 5-7 hours |
| Video Streaming | 3-5 hours |
| Gaming | 1.5-2.5 hours |
| Mixed Use | 4-5 hours |
| Standby/Sleep | 24+ hours |
Important Note: These are conservative estimates for a new battery. Actual runtime may vary based on your specific laptop configuration, age of other components, screen brightness, background applications, and system settings. A replacement battery used with older hardware typically provides shorter runtime compared to when your laptop was brand new due to increased power demands from aging components and modern software.
