How much battery life can I get out of a non vv pv vs a vv pv? I read that my vv chrome young june lavatube uses 30% more battery compared to the regular black or silver lavatube. My battery life with efest imr 18650 is not great, max is a day if im lucky. On average i would need to pop in a 2nd battery at night and combined with a couple of technical problems im considering to get another big bat mod. Im hoping I can gain a lot more battery life with a cheap non vv tube mod with unregulated mode, or a mechanical pv. I get soo jealous that people can get 2+ days vape time on a 18650 ego tube mod. Also is there a difference in how much battery is used when vaping 3.6v on a non vv and a vv mod?
