Damn... looks like my unit is having the same issue as reported earlier by many regarding the battery drainage. I have 3 different batteries, so I know they are not the issue. I fully charged my unit last night with the brand-new included battery (this took very long, longer than it should have), and I just turned the unit on to receive a notice that the battery was low (on its last bar). I'm still mid-session, but I am getting alerted about the low battery. Mine also shows different battery levels upon turning on. It will often display a half-charged battery only to vibrate and indicate low-battery a moment later. It is confusing because when out yesterday, I wasn't sure what level the battery was at The unit functions beautifully when it works, but the battery issue along with the vape randomly turning off has me thinking something is amiss. My partner purchased through VapeWorld, so I hope they handle the issue quickly! Edit: It looks like mine turns off when it is set down as well!
