I have the Blu ecig kit with the PCC, which is fantastic and convenient and all that, except for one thing that I can't figure out - I've been giving my boyfriend one of the Blu cigs for him to use to decide whether or not he wants one, and somehow he's managing to kill the battery within a few hours, whereas it's taking me about a day to a day and a half to kill one. With him being at work and unable to vape at random, shouldn't the battery be lasting him longer? And it's not one particular battery, because we trade off - as soon as one dies, I give him the other one that's been charging. So I'm just confused. What's he doing different that's causing the batteries to crap out so much faster?
