Battery Lifetime #3
Comments
Hi @3xpla1n , I think you should be getting more battery life than that, but I haven't measured mine, to be honest. Have you checked nVidia vs. nouveau? You can also check PowerManagement/ReducedPower. If you do, please report back, it'd be useful to know how it goes. |
I didn't measure precisely either how long the battery lasts with Ubuntu, but it looks like it lasts longer with Windows 10.. I'll try to take a closer look and post some details here. |
@antoinm great, what graphics driver are you using and which screen brightness (I'm always using max. brightness)? |
Thanks @rcasero for the great doc! Followed most parts there for my 9560 setup. I went directly with 17.04 and except for nvidia/intel gpu switching everything pretty much worked out of the box using the 387 version of nvidia driver. Regarding battery life, I recommend installing After adding that and installing bumblebee you should see a power consumption of 15±5 kwh. Improvising slightly I also added After this you can test with |
I've installed the nvidia driver and the battery of my dell laptop is only lasting 2 hours (maximal brightness, always on).
Are you experiencing such a small battery lifetime as well? Have you done anything to improve this issue?
