Battery drain on ubuntu is fast

I have a Samsung NP530U3B-A01: - intel core i5 2467M - 4gb ram - intel hd 3000 - 500gb hard drive

It's dual boot with windows 7. I've seen if i unplug the baterry charger, the battery indicator remains as if is still charging and the oposite happens to.

And the power comsunption is HUGE. In windows 7 i got comsuptions around 7w in idle. In Ubuntu 12.04 is around 18w in idle.

I really like ubuntu but with this power consumption i can only got 1h of battery and i dont want to use an OS that can't give me a nice battery life :(

  • Can you try to install Jupiter? It's an "appindicator designed to improve laptops / netbooks battery life" From webupd8 – Marius Balaban Apr 26 '12 at 22:24

  • I think he is asking how to change the time remaining to battery percentage? I got to admit I really hate looking at time remaining and would prefer to see percentage. The option was there in 11.04, I don't understand why it was taken out. Please help. –  Sep 10 '12 at 12:27

  • there's two questions here - one is about the high usage and the other is about the battery indicator - I came here looking for a solution on the first :/ – sevenseacat Jan 21 '14 at 07:04
