Pick a game to auto-set its typical TDP, or choose a level manually below.

TDP based on gameTDP values per game are general guidelines based on typical genre/graphics demands — not measured benchmarks for any specific device. Actual power draw varies by device, settings, and upscaling used.

Formula: runtime = (battery Wh × efficiency) ÷ (TDP + system overhead). Battery capacities come from manufacturer specs or verified teardown data; devices marked "≈" use community-sourced figures and may differ from your actual unit. Results are estimates only — real runtime also depends on screen brightness, network use, and overall system load.
