Ubuntu: Battery is drained too quickly


I'm getting really low battery life under ubuntu, not even close to windows. I tried powertop, and I saw that my laptop is consuming in idle nearly 20 watts (a bit more).

I tried to install laptop-mode-tools, change "good" into "bad" in powertop, but nothing changes. I see that I have the the HD audio output device which is running at 100% every time. Could this be the problem?

This is a report from powertop.

The battery reports a discharge rate of 22.8 W  The estimated remaining time is 33 minutes    Summary: 381.8 wakeups/second,  0.0 GPU ops/second and 0.0 VFS ops/sec                Usage       Events/s    Category       Description            3.2 ms/s     182.7        Timer          tick_sched_timer          100.0%                      Device         Audio codec hwC0D3: Intel            7.9 ms/s      25.1        Process        /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background no            1.9 ms/s      24.2        Interrupt      [6] tasklet(softirq)            2.9 ms/s      23.2        Process        /usr/lib/chromium-browser/chromium-browser --type=zygote            8.1 ms/s      20.3        Process        /usr/lib/unity/unity-panel-service            0.7 ms/s      17.4        Timer          hrtimer_wakeup            4.2 ms/s      12.6        Process        unity-2d-panel          604.4 µs/s       9.7        Process        syndaemon -i 2.0 -K -R -t          149.7 µs/s       9.7        kWork          ieee80211_iface_work            0.8 ms/s       8.7        Process        metacity           19.5 ms/s       1.0        Process        powertop            3.0 ms/s       6.8        Process        //bin/dbus-daemon --fork --print-pid 5 --print-address 7 --session          699.0 µs/s       6.8        Process        /usr/lib/thunderbird/thunderbird            4.3 ms/s       4.8        Process        gnome-terminal          658.9 µs/s       2.9        Interrupt      [1] timer(softirq)           75.1 µs/s       2.9        kWork          iwl_bg_run_time_calib_work          163.8 µs/s       1.9        Process        /usr/lib/accountsservice/accounts-daemon           70.6 µs/s       1.9        Process        [ksoftirqd/2]           25.8 µs/s       1.9        Process        [ksoftirqd/0]            1.0 ms/s       1.0        Process        /usr/bin/python /usr/sbin/powernapd          408.2 µs/s       1.0        Process        unity-2d-shell          189.8 µs/s       1.0        Process        /usr/lib/chromium-browser/chromium-browser          124.4 µs/s       1.0        Process        /usr/lib/unity-lens-applications/unity-applications-daemon          113.3 µs/s       1.0        Process        /usr/lib/gnome-settings-daemon/gnome-settings-daemon          112.0 µs/s       1.0        Process        nautilus -n          104.9 µs/s       1.0        Process        /usr/lib/gvfs/gvfsd-trash --spawner :1.2 /org/gtk/gvfs/exec_spaw/0           77.5 µs/s       1.0        Process        /usr/lib/x86_64-linux-gnu/colord/colord           75.6 µs/s       1.0        Process        /usr/lib/gvfs/gvfs-gdu-volume-monitor           75.0 µs/s       1.0        Interrupt      [53] i915           74.9 µs/s       1.0        Process        /usr/lib/gvfs/gvfs-afc-volume-monitor  

What should I do to make the battery consumption lower?


You should consider installing jupiter

You can select power modes with it, and it's very easy to control. It really saves out battery.

Open terminal and do this.

Add the repository

sudo add-apt-repository ppa:webupd8team/jupiter  


sudo apt-get update  

Install jupiter

sudo apt-get install jupiter  

And to other people reading this and are using an Asus EEPC netbook, install this asswell

sudo apt-get install jupiter-support-eee  

Have a nice day :)
