Battery drain on ubuntu is fast
I'm currently getting 7–8 hours of battery life whilst using Windows, but I only get about 3 hours in Ubuntu? Why the big gap?
Some theories of mine:
- Specialised/optimised drivers in Windows
- More resource usage in Ubuntu
- Lack of effective power-saving feature in Ubuntu, vs. Windows, which specifically tries to reduce battery usage when on battery power
- Dell has a conspiracy with Microsoft.
Seriously, though. I have a 9-cell battery; I should be getting much better life, right?
Any way to solve this problem?
