Using tlp and powertop can significantly improve the battery life.
I didn't know powertop, I'll give a try. Thanks
This is my gripe, unless you spend hours customizing each laptop ubuntu makes a 10 hour battery life shrink to around 2 hours with only the default 'power saving' features turned on.
And the bad NVIDIA support !
Well was that with Apple products?
The reason why I mentioned Apple Products is that Macs battery life on non OS X operating systems have poorer battery life.
