Depends. You using more
batteries to facilitate that higher voltage?
If not, no real benefit as far as the battery's concerned.
Edit: Just saw the thread title. Only difference between VV and VW will be if the
device is actively checking the atty resistance during use. In that case the wattage output won't change during a pull on VW while on VV with the V being steady and the resistance changing, the watts will change.
Though VV and VW both do the same thing. They both set the voltage to acquire the desired vape. Any difference in actual use is likely to be so minute it's imperceptible.
