Where are the battery graphs?

  • 772

Once upon a time, when I went to the battery icon on my netbook, I could get it to show me interesting graphs of the battery state, and how it had changed over time.

Nowadays, in this time of decay, all it will give me is a tooltip telling me how long I've got left, or how long to recharge.

Does anyone else remember the golden age of which I speak, or have any advice on how it might be regained?

    Unity Users:

    When you click on the indicator, and you see the time left on your battery, click that menu item. It should open a window that allows you to see this info:

    KDE Users:

    You can find this info under "Energy Information" in Kinfocenter. Note that you won't find any graphs on a system that is plugged in.

  2. GNOME Users:

    Simply run gnome-power-statistics in a terminal

    or open the Power Statistics app from the GNOME Shell

    Since you asked for this:

    I could get it to show me interesting graphs of the battery state, and how it had changed over time.

    1. Go to the Laptop battery option
    2. Select the History tab
    3. Uncheck Show data points at the bottom if you want

    And you will get a graph like this:

  3. While I haven't seen the behavior that you're talking about (I've been using Ubuntu since 10.04, so it hasn't been that long), I do know that you can install a battery graphing package. Instructions below:

    1. Install battery-stats from the software center .

    2. Run battery-graph by hitting Alt-F2 and typing battery-graph

    There you go! Example screenshot shown below: I've been plugged in, so my battery's been the same
