Recently I installed Xubuntu which being awesome and far better than Ubuntu' s Gnome lacks some of the features like showing estimated battery time remaining.
I tried a lot to find out a solution for this recently came across a ask Ubuntu thread which describes a way to obtain battery details using Terminal.
Using upower you can get all the battery details.
To view all the details you can use
Use grep to remove the unwanted details from the above result
You can create alias for the same command so that you can run it using just the alias that you gave
To permanently add this to your system terminal just copy paste the same command to .bashrc or /etc/rc.local
