Battery Life Ubuntu Vs. Windows
location: ubuntuforums.com - date: January 3, 2009
I've always just accepted that my battery life is pretty crap on my laptop, but I booted windows the other (hasnt been done in about 3 months) and when I usually have about 35 minutes at 40% charge, I had an hour under windows. Does anybody know why this could be?
Best Linux distro for optimize battery consumption (Asus EeePC)
location: linux.com - date: March 28, 2013
I'm very new here and I'm not sure if here is the proper site to post this question (I apologize if not).
I've using linux for a couple of years (Mint) trying to move from windows to Linux. I've an old Asus Eeepc 1005HAB with XP and I've installed LinuxMint Isadora (Gnome) with dual boot. I'm really really happy with the performance of the system, but the problem is that the battery consumption is very hard: with windows the battery last more than 2 hours, but in Linux it hardly reach the 90 minutes (without using video and/or audio). It's truly annoying because I really DO LIKE LINUX!!!
I've investigated several solutions. For example, moving to LXDE I've noted a drastic increase in battery life, especially when using powernowd to configure processes and eeepc applet (don't sure if jupiter and eeepc applet obstaculizes each other).
But I'm thinking about moving to a distro that be focused in optimizing the battery use, mainly by including built-in kernel configurations a
Google Chrome CR48 Ubuntu Battery Life

I am finding conflicting reports of Ubuntu's battery life feature on the CR48. Is anyone familiar with how much the battery can be maxed to on Ubuntu vs the Chrome OS 48?
Running Gnome 3, battery notifications?
location: linux.com - date: August 5, 2011
I just started running Gnome 3. At first I hated it, but in a short amount of time it's grown on me and I'm very impressed.
It functions well in Natty, no issues so far. The design team outdid themselves.
I'm running it on my laptop though. The only thing that bothers me are the notifications.
I get "Battery Discharging 99%"
"Battery Discharging 98%"
So on and so forth every few seconds.
I read something about a power manager in the G-conf files, but I can't find that specific file.
Is anyone else running Gnome 3, and know how I would resolve this?
Thanks in advance.
12.04 has your battery life improved?
location: ubuntuforums.com - date: April 30, 2012
One thing I have seen touted in regards to 12.04 is improved power management.
Since Oneiric, I haven't seen any improvement at all and battery life is still much shorter than either Windows 7 or Kubuntu.
Restore Battery Icon on Ubuntu 12.04 Unity 2D?
location: linuxquestions.com - date: July 15, 2012
Hi, I recently installed Ubuntu 12.04 on my old ibook powerpc. Installation runs great for the most part. When I installed 12.04, my laptop battery was 100% dead, and I think when the installation tried to detect it, it found no battery and so did not put an icon in the tray. Since then, I put a new battery in the ibook, but still no indicator. Rest of the icons are there though (mail, wireless, sound, calendar, etc). The machine is detecting the battery though. At the terminal, I can input [cat /proc/pmu/battery_0] and I will get a readout for the battery usage and time remaining. A good work-around, but I'd like to get my battery icon reinstalled. I also installed wmbatppc from synaptic. It allows me get a percentage of remaining battery charge too. But it is also run from terminal. 12.04 uses unity 2D. Any ideas on how to get my battery icon?
Thinkpad X220 short battery life with Ubuntu 12.04
location: ubuntuforums.com - date: May 12, 2012
Apparently Ubuntu 12.04 was meant to support the laptops better and allow a longer better life.
On Win7 I get 7 hours battery life with my 6 cell battery. Same laptop on Ubuntu is around 2 hours. Thats too much of a difference.
I have tried PowerTOP and switched some entries to GOOD in order to save battery life, but without a big success.
Any idea what to do?
HORRIBLE 11.10 battery life fix anytime soon?
location: ubuntuforums.com - date: November 3, 2011
I updated from 11.04 to 11.10 earlier this week, and though I'd heard reports of increased power usage on oneric, this is crazy.
I have a relatively new Lenovo x220 (core i7) with a 9-cell battery. With screen dimmed a bit and intermittent wifi use under Windows 7 I can easily get 8+ hours (and could push it to 12+ using Lenovo's power-usage tweaks). On Ubuntu 11.04 I still got a decently respectable 6+ hours. On Oneric, I'm getting around 4 hours with wifi turned off - that's a third of the battery life I can get on Windows. This is unacceptable.
What the heck is going on? I've heard this is somewhat kernel related, but even so, this seems insane to me. I've been on Ubuntu for six years and hate the prospect of having to turn back to Windows. I opted for this laptop specifically for the battery life, and the insane power consumption is making 11.10 practically useless for me. I'm tempted to revert all the way to 10.10 to see if I can at least get 7 hours with gnome2 and an
Increase battery life on HP laptop w/ dual graphics
location: ubuntuforums.com - date: June 10, 2012
I have a dual boot with Win 7 and Ubuntu 12.04. The laptop got about 3 times the battery life with Win 7 as with Ubuntu.
I suspect part of that is that Ubuntu is running the Radeon graphics card full-blast, rather than just using or switching to the on-board Intel GPU. Installation of proprietary drivers via Additional Drivers fails with error messages. I see no fix available online. I also tried various tutorials to install Catalyst directly. This also fails with error msgs and I don't see anyone online suggesting a fix for these errors.
However, one positive side-effect of partially installing Catalyst seems to be that a) 3D doesn't work, and b) power consumption is down sharply. I'm guessing I (partially?) disabled the Radeon GPU. On the other hand, I think I still get about half (75%?) the battery life off Ubuntu than Windows.
Just how much power I'm saving is unclear. powertop says the battery discharge rate is 25-30 W (watts) when I first start it up, but this q
Windows to Ubuntu battery life sucks now

Lenovo Ideapad P400 Touch laptop, Core i7 3632QM, 8GB DDR3, 1TB 5400RPM SATA, Intel HD Graphics, 14" 1600x900 Display
Suddenly battery life is much worse compared to Windows 7 and 8 both of which had about two hours more.
Any ideas why?
I've installed all Ubuntu updates and used a freshly downloaded ISO as of yesterday so I'm definitely running the latest 13.04 64-bit.
