What ohms LR?
And how often are you dragging on it? Continuous?
One guy was running through a 900mah battery in 2.5 hours by using 1.5 ohms on it (cuts your time in half) and vaping constantly (cuts your time in half or worse). So he was only getting 1/4 of the time that a person vaping moderately w/ standard resistance would get with the same battery.
100mah is about 1 hour of moderate vaping with standard resistance (like 2.5 to 3 ohms). I consider moderate to be vaping less than 1/2 the time.
What I do to not continuously vape is - at work a set the ecigs down. I have to use some self control. At home, I put the ecigs in a nearby room, not next to the TV or computer. I only put on by my side if I know I will be stuck away from the vaping room for more than 20 minutes.
