NEX-6 battery - horrible :( - Any tips?

Went from a D7000 to the NEX-6 without fully appreciating the longevity of the battery on an SLR. I'm on a trip now in Cambodia and I didn't last half a day before killing the battery (took about ~350 shots, so right on with reported life).

Does anyone have suggestions for stretching the battery life (aside from the obvious)? I'm really liking the camera aside from this MAJOR MAJOR MAJOR compromise. It's enough to make me want to return the camera.
