Intel's Core Ultra 2 Chip Posts Nearly 24-Hour Battery Life in Lunar Lake


We benchmarked a retail model Asus Zenbook S 14 with Intel's new and true AI-ready Lunar Lake platform and saw standard-setting battery results.

Our results were individually in line with what Intel itself has produced, and outside of synthetic test scenarios, these Core Ultra 2 chips have much higher TOPS ceilings that should enable efficient NPU background performance. To Intel’s credit, the gap between Nvidia’s entry-level RTX 4050 GPU in the Acer Swift X 14 and the Dell XPS 14 isn’t as wide as expected, but the Zenbook and other integrated graphics laptops still have their limits. We test each laptop and tablet's battery life by playing a locally stored 720p video file (the open-source Blender movie Tears of Steel) with display brightness set at 50% and audio volume at 100%.
