Estimated Battery Life by Usage
Based on 76Wh capacity with conservative estimates for typical Legion series usage:
| Usage Scenario | Estimated Runtime | Power Settings |
|---|---|---|
| Gaming (High Performance) | 1-1.5 hours | High performance mode, maximum brightness |
| Video Streaming | 2-3 hours | Balanced mode, medium brightness |
| Web Browsing & Office Work | 3-4 hours | Balanced mode, medium brightness |
| Light Usage (Document Editing) | 4-5 hours | Power saver mode, low brightness |
| Idle/Standby | 6-8 hours | Sleep/suspended mode |
Important Note: These are conservative estimates for a new battery 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.
