If battery life is of concern, as the regulator will draw current continuously, a buck step down converter could be used to improve that slightly, although they can be a bit noisy.
A separate circuit using a MOSFET could be utilized to completely cut off power to all parts.

Hi @vorillaz,
By chance did you take a peek at the breakout board schematic using a simple voltage regulator?
