Aside from the assorted obvious optimizations that people have discussed, it might be possible to "offload" the GPS to a separate battery-powered Bluetooth GPS receiver. I didn't see any results for this on a quick search, so I'm not sure whether it's been tested or not.
Of course, if you don't already have one a Bluetooth GPS receiver appears to cost at least 5x as much as a low-end external battery and 2-3x as much as a pretty substantial one.
