- cmm 7y agowith laptops, it really pays to make sure your kernel as recent as possible
- softwarelimits 7y agotry to put powertop --auto-tune into /etc/rc.local (before 'exit 0'!)
- egdod 7y ago4 years is long enough for lithium batteries to decline pretty noticeably.
- mceachen 7y agoYup, my xps 15 battery of that same vintage had to be replaced at the beginning of the year (under warranty).
- ZeroCool2u 7y agoSorry, the MBP was my old work computer. I don't have it anymore. I was referring to its battery performance at the time.
- ZeroCool2u 7y agoI think the big differentiator is power top actually. When I upgraded to 19.10, I was prompted to check the differences between the old/new versions of the power top config file. The new version had a few more comments and was clearly updated, so I used the new config file during the upgrade process and went through all the options to make sure they made sense for my laptop.
