I don’t think it’s the chip or process exactly. In my experience power management was very poor when using Linux on a laptop and required tinkering to get it inline with Windows. Is suspect the battery life seen with Apple silicon Macs is the OS + hardware. Maybe Framework is the right company to bring an ARM + Linux laptop with decent performance and battery life.
