Does it have a replacable battery? I'd be less annoyed about 4 hours of battery if I could swap.

(Also if anyone knows of a model that's got more of a focus on battery life for someone who is SSHing into external machines for most CPU intensive tasks I'd be all ears)

No, the XPSs don't have replaceable batteries either. The XPS 13 is a very tiny notebook/subnotebook, yet with full-size keyboard and all the performance of a larger notebook (it's very noticeably faster than my 2012 MacMini which also has an i7).

I guess battery mileage is mostly a function of the O/S and drivers, and your power settings and what you actually do on the notebook.

I have the Dell XPS 13 9350, bought used. When doing standard programming stuff (firefox + sublime + spotify, no CPU intensive tasks), I usually get around 8 hours of battery, so in practice it's never a problem.
