What battery device are you currently using, and what delivery system are you using on it?
I'm not a big fan of any string-wicked delivery system like a clearomizer or vivi nova tank, in fact I've given away my vivi nova tanks to beginning vapors because I stopped using them, but they are still fine for beginners because they are so easy to use. I just have never been impressed with their flavor production compared to a cartotank.
I have my theories on why this is so. A string wick system only has 2-4 strings carrying the
juice (flavor) to the heating element. That is a very small surface area.
A cartomizer, however, has ten-fold the amount of surface area surrounding the heating coil, allowing for much more juice (flavor) to be vaporized by the heating element. A properly set up cartotank allows continuous supply of juice to the cartomizer so that it never dries out which could result in dry or burnt hits.
