Estimated Battery Life by Usage
Conservative estimates for the 48Wh battery under different usage scenarios:
| Usage Scenario | Estimated Runtime |
|---|---|
| Web Browsing & Email | 3-4 hours |
| Word Processing | 4-5 hours |
| Video Streaming | 2-3 hours |
| Gaming | 1-2 hours |
| Mixed Use | 3-4 hours |
| Standby/Sleep | 24+ hours |
Important Note: These are conservative estimates for replacement batteries. When using a new battery with older hardware, actual runtime may be shorter than when your laptop was new due to increased power demands from aging components, software updates, and background processes.
