Microsoft uses a script to simulate web browsing. On 2022’s Intel-based Surface Laptop 5, it took eight hours, 38 minutes to completely deplete a battery; the new Surface Copilot Plus PC lasted two times that, hitting 16 hours, 56 minutes. That’s an incredible jump in efficiency, and it even beats the same test on a 15-inch MacBook Air M3, which lasted 15 hours, 25 minutes. That’s a whole hour and a half more.
