I would like to know what is the rank of the current LTS version in term of probable consumption of battery power -ie: for a same usage. Is the following rank probably correct, where top of the rank means "uses the highest level of battery power", and where bottom of the rank means "needs the less level of battery power":
Concerning Ubuntu 14.04
- Ubuntu Unity
- Ubuntu Gnome
- Ubuntu Gnome Classic
- Xubuntu
- Lubuntu
That will usefull for people who would like to optimize their instant battery duration, like travellers using laptop for example.
