Mac was already beating Windows machines on x86, when it came to battery life (especially when you consider battery size, too—the actually efficiency was much higher). I dunno how much they beat them on claimed battery life (because IME Apple is way, way more honest about how long their laptops run on battery, than PC vendors are) but real-world it was like 1.5-2x, for a same-sized battery on similarly-powerful hardware. Their iOS devices were also wildly more efficient than Android devices for years (may still be—I haven't had much exposure to Android devices in three or four years) despite both being on the same processor architecture, so it wasn't the architecture per se making them more efficient. Apple just seems to be the only major vendor that cares much about power efficiency at a software level. There's absolutely a ton of room for improvement on x86—Apple proved it when they were still on that architecture.
