I'm wondering if Xubuntu has the same features as Ubuntu 12.04
Particularly I'm trying to get the most battery life out of my laptop. Does Xubuntu 12.04 feature the same improvements to power management that come default in Ubuntu 12.04?
In general, is the difference between Xubuntu and Ubuntu simply the DE? Is all the underlying improvements available in both distros?

Xubuntu uses the same kernel as Ubuntu, as well as the same low-level power management utilities (hdparm, etc.), so yes, it has the same power management capabilities as Ubuntu.
But, Xubuntu may be more power-efficient than Ubuntu on your laptop, primarily because it's a "lightweight" desktop environment; it places somewhat less load on both your CPU and GPU compared to Ubuntu (Unity 3D). Whether it saves power over Ubuntu (and how much) depends on your specific hardware and use patterns.
