I
vape pretty much constantly... I would say 10 puffs or so every 5 - 10 minutes all day long. Using a passthrough (5v) on my 801 with my Kensington I can
vape the whole day without getting below 40% battery power. Actually I went a day and half last week without charging it (as I usually put it on charge before bed) and it was fine till I got to work where I charged it fully before going at it again.
Does this help?
