I figured that was going to happen. But a more valid test would be to start both computers at 100% battery. Run the XPS in lower power mode. Compare the performance and the battery life and then keep moving up the power requirements starting at 100% each time. Compare the performance against battery life. Then run plugged in and show the performance. Yes this would take more time but it would be significantly more informative.Maybe watch the entire video? The Xps died in the middle of the Geekbench compute test and he had to plug it in. The m2 still had 40% left. And he only briefly switched power modes to show the performance difference between the modes. The remainder of the test he had to run mostly plugged in since the battery was toast
Instead, this is more of the same "gotcha" and "OMG!, you won't believe what happened!" YouTube click bait that just happens to favor the Mac this time.
