Battery life with 15.04 and 4.16 Kernel #30

Closed growing closed 9 years ago

growing commented 9 years ago

Hi all,

I bought an XPS last week (non-developer edition, bios AO5) and immediately blasted windows with a total install of 15.04 (kernel 3.19) which worked pretty well out of the box (even the wifi) and got good battery life (> 7 hours at a push).

I was having problems with an external monitor so upgraded the kernel (as per http://hgdev.co/installing-ubuntu-15-04-on-the-xps-13-9343-2015-a-complete-guide/), which has fixed all the issues, except my battery life is now terrible; sub 3 hours even with screen dimmed, bluetooth off etc.

Is anyone getting good battery life with this setup?

Cheers,

Dan

Hi there,

Were you using any additional tools for power management under 3.19, such as TLP? I'm using 15.04 under 3.19, and my battery life was pretty sub-par until I installed the debian package laptop-mode-tools which can be acquired from here. This could be worth a try.

Hi Patrick,

No power management originally. I've worked out the problem; an app I was running (SQL client) was conflicting with gnome and making gnome-shell run at 100% which was nuking the battery. Closing that app has me back to the original battery life.

Thanks for the laptop-mode-tools suggestion, i'll give that a try.

Cheers!

Looks like this has been resolved.
