So I just bought the voopoo drag s on Thursday and so far battery life is HORRIBLE!! I am using a pnp 0.6 ohm coil at 20-24 watts and an only getting 277 puffs on a complete charge. It isn’t lasting me half a day. Does this sound normal, or is the battery defective ?? I have an aegis boost that I vaped at the same wattage, ohm coil and could easily get through a 13 hour shift before needing to recharge.
