Estimated Battery Life
Based on 41Wh capacity, here are conservative estimates for different usage scenarios:
| Usage Scenario | Estimated Runtime | Power Consumption Level |
|---|---|---|
| Web Browsing | 5-7 hours | Medium |
| Document Editing | 6-8 hours | Low-Medium |
| Video Streaming | 4-5 hours | High |
| Idle/Standby | 8-10 hours | Very Low |
| Gaming | 2-3 hours | Very High |
Important Note: These estimates are for new batteries. Actual runtime may vary based on your specific device’s age, software configuration, and power settings. Older hardware and modern software typically consume more power compared to when your device was new, which may result in shorter battery life than original factory performance.
