It probably lasted around 3/4 of a tank? I was messing around with flavors, so most likely it was around 3.8 with quick bursts of 4.2 on a new coil. And I use the standard coil that comes in the clearomizers. I really really love this vv, but mine has never lasted a whole day - and I don't always chain vape
Yes, Chesty, the button does flash when it's out.
Have you tried a different coil? A few days ago, I got the blinking lights of death and I assumed my battery was dead (even though I could have sworn it still had charge) and I swapped it for another I could have sworn had charge, but the same thing happened. I then tried a third battery that I new had charge (I swear) and the same thing happened. I tried a new coil and the problem was solved. My old coil must have been shorting out or something.
Could your coil be intermittently shorting out (is that even possible?).
