Macs have always had great battery life and the Apple Silicon chips took it to another level. It remains to be seen if any Windows laptop can actually consistently achieve their marketed battery life given Windows’ terrible track record for power management and proper sleeping.

Macs were long hindered by Intel processors to have long battery lifes AND/OR good performance. Two examples of MacBooks I had:

The 12" MacBook. Great form factor, bad software (graphics driver code was especially poor), poor keyboard, lousy battery life, slow CPU & graphics. Similar size now with the 13" MacBook Air, but much better.

The i9 MacBook Pro. Too heavy, not enough cooling, extra GPU chip (in the laptop) with lots of power demand, Thunderbolt chips with lots of power demand, CPU with lots of power demand, fans were often on (for example with anything which uses the extra GPU). Now a 16" MacBook Pro with Apple Silicon is virtually silent AND fast.

I currently have a Mac mini with M2 Pro, a MacBook Pro with M2 Pro and the new iPad Pro M4. All are very snappy and virtually silent. They use very little idle power and don't get warm in normal use. The i9 MacBook Pro would produce a lot of heat when attached to an external screen and doing a "simple" video call, due to the power hungry additional GPU needed to drive the external screen.

Yeah, no. Some macs had good battery life. The last Intel MBP was really bad though. (Less than 2h of basic desktop use and lots of overheating after a year)
