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?

There"s a lot more technical answers to this question but basically if you choose to use a 2 ohm atty at 3.6 on your vv mod and a 2 ohm atty at 3.6 volts on your non vv mod you will get abt the same battery life if everything else about your vaping style stays the same. VV or non VV mod isn't what makes the difference in battery life. All the variables of YOUR vaping is what makes a difference in battery life. Things like chain vaping verses taking 4 or 5 hits an hour make a huge difference. Do you use 3 mls a day or 7 mls a day ? Are you using a 1.7 ohm atty or carto at 5 volts or a 2.8 atty or carto at 4 volts ? Not that they are all that accurate as to their actual mah but you'll get longer on a 3000 mah 18650 battery then a 1600 mah 18650 battery. Do you take 10 second draws or 3 second draws?

When a newbie has speciifed they are looking for something that will last them all day I always cringe when I read people respond that they get a full day out of their 1000 mah Twist or 2 or 3 days out of their 18650 battery APV or even that every 100 mah equals an hour of vape time. Yes, there are people that will get these amounts of time but for many of us thats just not going to happen because there are far too many variables that effect the length of time a battery will last.

FYI, my 18650 batteries never last more then a full day on my non-vv APV's.

Just switched to a 3100 mAh 18650 around a month ago in my non-vv mod. I start the day at 4.1 volts and by the end of the day, taking close to 10-20 hits per hour on average Ill get down to 3.7 volts in a 15-16 hour period. That's on a 1.8ohm coil.

On my vv device which I really don't like to use, the battery will go down to 3.7 after only 12 hours on around 3.8 - 4.0 setting.

So I can definitely tell the difference.

It really depends on the device. Some are designed differently and are more efficient. The vv stuff with a switching regulator (Evercool and others) will be very efficient since they don't dissipate some of the excess voltage as heat. They switch on/off real fast instead.

That said, nothing is going to be as efficient as an all-mechanical mod (guessing here). But they aren't regulated so it follows battery voltage. They put nearly 100% into the coil. However, that's not always good either since people often recharge them early to keep consistency.

Then we can discuss dual battery configurations vs single battery boosters. Dual batteries are better in general for efficiency since they only "buck" the voltage down. Boosting requires additional draw on the battery to get the voltage bump. Then there's losses in the process.

Bottom line is that you have to look it up and become (unfortunately) an amateur electronics guy/gal to figure it all out.

I'm guessing that the all-mechanical mods are most efficient in general. Use protected batteries and make sure it is vented. The buttons will wear out over time too due to arcing inside...every time the button is pressed all the current goes through the button and it "sparks" for a millisecond. Nature of a switch.
