Estimated Battery Life
Based on 39Wh capacity, here are conservative estimates for different usage scenarios:
| Usage Scenario | Estimated Runtime | Power Consumption |
|---|---|---|
| Web Browsing | 3-4 hours | Medium |
| Document Editing | 4-5 hours | Low-Medium |
| Video Streaming | 2-3 hours | High |
| Gaming | 1-2 hours | Very High |
| Idle/Standby | 6-8 hours | Very Low |
| Mixed Use | 3-4 hours | Variable |
