I got the MVP 2 last week and couldn't be happier with it! I binge vape like crazy on it and it works like a champ. I can't imagine how long it would take me to run it dead, I vape like crazy and the batter barely drops on the display. I charge it every couple days regardless as I was thinking that when it starts to lose it's charge it would go quickly? My question is do I need to be running the battery down low before recharging it?
It should drop faster from 4.2 to 3.9
flatten out at 3.7 and stay there the longest
go down to 3.5 then drop fast from there to about 3.3 then the mod will cut off to prevent it getting too low.
No you don't need to run down the battery before recharging; in fact it needs to stay over 3 volts.
Best to keep it in the 3.5 to 3.9 region.
