I am honestly a bit shocked at the low numbers you and parent are reporting. I have not used Windows in a long time but Linux is generally assumed to be less power efficient on laptops and yet I have no problem getting 7-9 hours out of my year old ZenBook 13 OLED.

That's still nowhere near what you get on a MacBook Air but perfectly usable imo.

My experience with Linux, Ubuntu and Fedora on HP EliteBook and Dell XPS13 respectively is similar to the Windows numbers posted above.

My 2014 MBP13 still gets better life than my daily driver XPS13 9370.
