I think it's probably more Chrome's fault as Safari is known to be more optimised for battery. Likewise old Edge was pretty good for battery too. I know that if I use the native Windows Store based Netflix app on my laptop (Ryzen 4800u) I get much much longer battery life than if I use Netflix through Chrome. But it's still a long way off what you'd expect from a device with a battery so large compared to a phone. I think the M1 Mac vs Intel Mac battery life comparisons showcase the difference in CPU efficiency the best.

In my experience, Safari (and old Edge) were more willing to let pages crash or limit CPU cycles for the sake of system performance, while Chrome is content to let pages allocate as much RAM and use up as many CPU cycles as they want, letting poorly behaved websites work while sacrificing the rest of the system and battery life.
