I recently moved from a MBP2015 to a MateBook X Pro and what I like more is the battery life, I can work a full day without plugging it in (I work from coffee shops). One reason for the long battery life is the 15W CPUs in ultrabooks, as opposed to 45W in bigger laptops. Here are some things I did to boost my battery life (I get 7~10h)

- Undervolted the CPU (-100mV). - Using bumblebeed/bbswitch to switch between GPUs, I never use the discrete GPU but I'm glad it's there just in case. - Show power consumption (watts) on my status bar to keep an eye for power hungry websites - Using Arch so it doesn't have anything I don't need running out of the box. A bit harder to install and configure though. I'm actually not sure if this helps or not - Disabled Xorg compositor, yeah, I don't get window shadows and there's a weird flicker when I switch desktops but it gives me an extra 10~15% battery life.

There's also a utility called "powertop" that gives you stats about power consumption and a bunch of levers to improve it.

It took me a few days to set everything up but now I'm in love with the mobility.
