Whenever I plug my charger out, the lifespan of my battery suddenly drops from 90 minutes to 30. By "suddenly" I mean it literally takes it around 10-15 seconds at most to drop. My battery isn't new, but it isn't broken either (lasted 2-2.5 hours unplugged on Windows 8. Not much, I know, but it's not 30 minutes either)

I've been searching for answers for quite a while now (even the "possible answers" list had quite a few similar topics) but I did not seem to find a helpful answer. Maybe it's because I'm bad at searching, maybe it's because I'm still slightly freaking out.

Either way, your guidance would be very helpful.

Using 13.04, 64-bit.

PS.: I have Jupiter and Intel Graphic Drivers for Linux installed already.

possible duplicate of Is there a power saving application similar to Jupiter? – Alvar Oct 6 '13 at 18:57
@Stan You can use powertop to see what is draining your battery power. Also providing your machine specs (CPU, Optimus/hybrid GPU technology?, etc) should help to diagnose your problem. – Salem Oct 6 '13 at 20:06
@Stan: The possible reason might me your graphics card driver. It is possible that no graphics driver installed for your laptop, all burden goes to processor and it consumes a lot of power. Same happened to me with HP Pavilion laptop with AMD Radeon graphics cards. After installing graphics driver my problem solved. I suggest you to post some more info about your laptop and graphics cards – Saurav Kumar Oct 6 '13 at 20:55
Run upower --dump and add the output to your question. – psusi Oct 7 '13 at 1:37
