Brand new Dell 7000 series Inspiron 15 runs perfectly under Mate 18.04, but battery life has crashed from up to 8 hours on Windows 10 to barely 1.5 hours. TLP installed, but doesn’t seem to have made much difference. This seems to be a common problem, and must be one of the last remaining reasons stopping people switching from Microsoft, so is there likely to be a real solution any time soon?
Have you seen this?
It might give you a few ideas.
