I recently installed Fedora 30 for work on my Gigabyte Aero 15X v8. I blacklisted nouveau drivers as I don't need the discrete GPU while working and installed TLD. But even after that, the battery life is around 4-4:30 h versus more than 6 on Windows.
I installed powertop to see what's going on and I saw that this tick_sched_timer was drawing more than half of the laptop's power. Apparently quite a few other people experience it from what I searched, but I coudn't find either an explanation or a solution.
Is it normal ? Or is there something that can be done ?
