  • Energy when full - 231.7 Wh

  • Energy(design) - 81.2 Wh

This also results in an incorrect value for Percentage - 31.3%

This also conflicts with Time to full field (Thankfully !)

enter image description here

I have never seen this difference before. Why is this happening ?

Can this damage the battery or my laptop in any way ?

My laptop is Asus U32U - RX012D.

On second thought, while I'm glad you're reporting the bug, I think maybe we shouldn't close this question, since the information in the answer about why this doesn't constitute a risk to your computer could be valuable to other users. We may have other questions we close as duplicate of this... –  Eliah Kagan Jan 13 '13 at 3:35

Posting as an answer as it needs some more explanation besides "close it - it's a bug!".

Why is this happening ?

This is a bug. Could be in the GUI, upower frontend or in the kernel. I can't tell really, but, go here:

Can this damage the battery or my laptop in any way ?

No, Ubuntu does not control the power controller and in most cases it can't do anything with it besides reading states (exception here are Thinkpads with the fancy thinkpad-smapi module).

I had thought as much. However, the problem seems to have gone on reboot. Also, that was the first and only time i had seen this and i have made no recent changes to the system. –  AsheeshR Jan 12 '13 at 16:51
    
@AshRj That's another indication of it being a bug. :) –  gertvdijk Jan 12 '13 at 16:52
    
Shouldn't bugs be reproducible ? –  AsheeshR Jan 12 '13 at 17:01
    
Hard to reproduce bugs are still bugs. If they appear often and hard to catch some people call them "hairy bugs". :) Anyway, if you have it, you should include a path to reproduce, yes, but you'll probably be given advice what to do when it happens again for more information. –  gertvdijk Jan 12 '13 at 17:07
