Doesn't matter though. Every single one of these "casual" users I know has a terribly outdated device with a broken battery that doesn't even charge anymore.
Laptop battery is mostly an issue of inefficient CPUs nowadays. I don't know about other distros, but at least Fedora's default power saving settings give a battery life very much comparable to Windows. Which is obviously still nothing compared to macbooks or even snapdragon laptops.
not the same thing at all. Different userspace that may or may not be that efficient at power, as well as well tested power management in the kernel for specific devices.
