I've been having some issues with battery life, perhaps due in part to the age of the battery, but I'd like to squeeze out every last minute I can. I've heard that 13.04 is developed with mobile devices in mind and has some emphasis on battery life. Can any laptop users report on how it has positively (or negatively) affected their battery life, in relation to 12.04/12.10?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.
Due to the fact that it uses less resources and is therefore faster, and the kernel has better power management, Ubuntu 13.04 has better battery life than Ubuntu 12.04.
Apparently, Ubuntu 13.10 is doing so well on resource consumption that it even works on really ancient and slow PCs.
