A device that recharges the pen only 7-9 times is broken and can be changed under warranty for no charge. Either that, or your device was a replica, seriously.

I highly doubt someone's smoking style affects the battery power of the smoking pen, because, if you smoke from it like a train engine, it's just got nothing to burn anymore and shuts off - like a normal cigarette. There's nothing related to the battery itself.
