Estimated Battery Life
Based on 72Wh capacity, here are conservative estimates for different usage scenarios:
| Usage Scenario | Estimated Runtime | Power Consumption Level |
|---|---|---|
| Web Browsing & Email | 4-6 hours | Low to Moderate |
| Document Editing | 5-7 hours | Low |
| Video Streaming | 3-4 hours | Moderate to High |
| Gaming/3D Rendering | 1.5-2.5 hours | High |
| Standby/Sleep Mode | Multiple days | Very Low |
| Mixed Typical Use | 4-5 hours | Variable |
Important Note: These estimates are for new batteries used with older hardware. Actual runtime may be shorter than when your laptop was new due to increased power demands from software updates, hardware aging, and background processes. Screen brightness, connected peripherals, and system settings significantly impact battery life.
