> Granted I'm still scared to run Linux on a laptop as I don't believe I will get the same battery life out of it as I do with Windows.
Using tlp, setting all settings in Powertop and undervolting with intel-undervolt will get you some seriously crazy battery life. Battery life on my X250 is better under Linux than it is in Windows with these changes.
I get 5 hours battery life on my dual Xeon laptop under Linux.
I will say, I miss 2016-era power controls for Linux. Being able to set a max MHz allowed me to truly control my power and battery usage. Any idea why Linux changed that functionality in future power governers?
