You are correct about battery energy, but note the minimum voltage for the AA cells you are using. At 2.1v, each cell is providing 1.05v, which is at or near the 'end voltage' for many chemistries. I wouldn't be surprised if the energy cost of additional power conditioning (the parts would draw power themselves) exceeds what little extra you can scavenge out of the cells.
