How to fix ubuntu battery issue

 

If you have run or are running Ubuntu 11.04/11.10 you may have noticed that the battery life can be quite abysmal compared to that of Windows. This is due to poor power management settings and defaults. Its not that your Ubuntu is consuming more power but instead once your battery reaches a certain percentage (Mine was about 75%) it would display a “Critical battery” level warning. My PC would then shut down 5 minutes later with over 70% battery remaining

To solve this problem enter the following command in a terminal window

For Ubuntu 11.04:

gconftool-2 –type bool –set /apps/gnome-power-manager/general/use_time_for_policyfalse

For Ubuntu 11.10

 gsettings set org.gnome.settings-daemon.plugins.power ‘use-time-for-policy’ ‘false’

This will not fix the actual issue but it will disable the system standby for low battery levels. I get roughly the same time on Ubuntu as I do on my Windows partition. Hope this helps.

An actual patch is in development (at the time of writing) and should be available soon enough
