Linux battery life is currently borked IMHO. Needs some major optimization / tuning to come close to Windows right now. Am currently dual booting Windows 11 / Ubuntu, but was previously running F39 beta.
Screen shot shows nearly ~4 hours of screen on time, 10 hours of sleep time over a 24 hour period and only used 45% battery total. Mixed productivity usage.
Edit: Also attaching my estimated battery report
