Battery on my recent Dell is over 10 hours with Firefox usage. Leaps and bounds ahead of where things were at 4 years ago. Libinput, while less fully featured than synaptics, seems to have a better physics model for the trackpad pointer translation. It still doesn't have fractional scrolling though, every scroll is still a discrete increment.
