I really want to love Linux but...

post #1 of 39
Thread Starter 
it just eats my battery life like no other! I've installed various Linux distros on my Dell Studio XPS 16 and I literally get less than 1.5 hours of battery life on all of them. On Windows I'm able to get about 4 hours. Why? Why can't I use Linux on my laptop?

Not a expert in Linux but that really sucks. Have you tried Ubuntu?

I've tried Ubuntu, Linux Mint, Fedora, and Debian and all of them drain battery like no other.

I've never tried Arch. I'll definitely give it a try.

I get about 5-7 hours with my Dell Latitude E5400 & Arch ( I keep my screen brightness down all the way as it's still perfectly readable most of the time ), last time I had fedora on it the life got cut in half to about 2-3 hours at most.

Some decent tips;
http://www.howtogeek.com/55185/how-to-maximize-the-battery-life-on-your-linux-laptop/

Basically clock down your cpu, screen brightness, no need to keep an ethernet port open, and all that jazz.

If you install the desktop distro of Ubuntu, it really does suck up more power, all the things are there, you just have to configure it for less power draw, google around the linux community, there are free add-on programs that will help with power efficiency

One does not just "try" Arch wink.gif

It takes a fair amount of proficiency to even get it installed. The documentation is great, and I enjoyed learning Arch, but I was doing it as a project, not setting up my primary OS. It so happens that Arch is my primary OS now (because it's amazing!), but for a Linux beginner looking for a out-of-the-box ready distribution, I think there are better choices.

Or perhaps not. One of the reasons that Linux uses so much power right now is that there is a bug in kernels < 3.3. All non-rolling release distributions still use 3.2, as far as I know, so maybe, if you're not in a rush, you should give Arch a try.

That's awesome! What DE/WM do you use? Did you just use acpi, or other things?

Correct me if I'm wrong but aren't most distro's "stable" release still using kernels with the power regression bug? Hasn't that been a relatively recent fix in terms of stable/mainline kernel releases?

That could very well be chopping battery life off at the knees.

Sounds like it. The power regression bug was formally fixed in kernel 3.3, so Arch might fix your problem.
