Ubuntu 14.04 Battery Icon has fixed value after booting till the next reboot [UPDATED]

Question

I have a dual-booted Ubuntu 14.04 LTS with Win8.1 on a Dell inspiron 14 series 5000 machine. It tire me with alot of bugs starting with wireless instability and showing new ones with each update I guess.

Recently, when I start my computer, the battery shows a correct percentage whether power is plugged in or not but it never changes. The value is fixed until the power is drained completely, only then I know I should plug the power in. When running :

 upower -i /org/freedesktop/UPower/devices/battery_BAT0

I get:

  native-path:          (null)
  power supply:         no

  has statistics:       no

    warning-level:       unknown
    icon-name:          '(null)'

and when running:

upower -i /org/freedesktop/UPower/devices/battery_BAT1

I get:

     native-path:          BAT1

The time to empty is the real time not the displayed one in battery icon.

[UPDATE] Running:

acpi -b

Gets me:

Battery 0: Discharging, 15%, 00:32:53 remaining

What make and model of laptop are you using? You probably need to change the ACPI set up. Relevant: http://askubuntu.com/questions/100325/how-to-get-the-correct-battery-status — Wilf, Sep 14 '15 at 18:36
@Wilf , I didn't always have this problem as that post's author. and running acpi -b gets me different result. updated the post with lap model & results of that cmd — user2949483, Sep 14 '15 at 18:43
Try running this command: sudo apt-get install acpid acpi-support — Daniel, Sep 14 '15 at 19:34
@Daniel acpi-support is already the newest version. acpid is already the newest version. acpid set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded. — user2949483, Sep 14 '15 at 19:39

Find your model and see if there are known issues and solutions — Daniel, Sep 14 '15 at 19:41
Nope. tried what you suggested. I'm afraid it's a conky/compiz thing bcuz when I click on the battery icon, the details window shows correct info too just like the terminal. — user2949483, Sep 14 '15 at 22:54
