Solution 1

Optimize your screen brightness, so it consumes less power.

Or you should also monitor your system activities by ctrl + tab and see if any process consuming lots of CPU and resources, Consuming more CPU results more heat up and less power.

Or you can install PowerTop to see what's taking the power so you can optimise your system.

To install: sudo apt-get install powertop

Solution 2

For me tlp has worked best. Try installing it as described here. You will have to purge laptop-mode-tools package if it is installed on your system else tlp will refuse to start.

I did a clean install of Ubuntu 14.04, along dual booting Windows 7.

I love Ubuntu but then suddenly the power went out and the next thing I know my battery ran out of juice in less than 30 minutes.

Usually my battery lasts for 3 hours with Windows 7, but on Ubuntu its considerably less please give me some advice.

  Did you have the laptop plugged into the charger when the power went out?

  You probably shorted out the battery.

Actually, to fix my problem I had with my radeon card (in ubutnu 13.04) I added the following code to my rc.local to disable vgaswitcharoo: chown USER /sys/kernel/debug/vgaswitcheroo/switch echo OFF > /sys/kernel/debug/vgaswitcheroo/switch modprobe radeon
