Estimated Battery Life
Based on 21.9Wh capacity, here are conservative estimates for different usage scenarios:
| Usage Scenario | Estimated Runtime | Power Consumption Level |
|---|---|---|
| Web Browsing | 3-4 hours | Medium |
| Document Editing | 4-5 hours | Low-Medium |
| Video Playback | 2-3 hours | High |
| Standby/Sleep | 20-30 hours | Very Low |
| Gaming | 1-2 hours | Very High |
Important Note: These are conservative estimates for new batteries. Actual runtime may vary based on your device’s age, software demands, screen brightness, and background applications. Older hardware and modern software typically consume more power compared to when your device was new, so expect slightly shorter battery life than original factory performance.
