Arm vs. x86 In the Real World: 24-Hour Battery Benchmarks

Battery life claims on manufacturer spec sheets are notoriously measured under unrealistic conditions with dimmed screens and paused Wi-Fi. In our real-world multi-task suite, the efficiency of ARM architectures like Apple Silicon continues to outshine high-wattage x86 architectures when away from wall outlets, while Intel Core Ultra NPUs are rapidly closing the gap.
