Thanks.Had mine for a weeks or so. No issues with battery like, lasts longer than the original.
Not really paid attention to the charge percentage, although I do see it jump when activating the screen, I take that to be it initially showing the last reading when the screen was active and updating to current.
Charges twice as fast compared to the original, 2A vs. 1A charge, 30-40 minutes to full charge. As expected.
Yes, puff counter resets after charge, works for me, no real care for puff count…
Perhaps you have a dud, it happens. Talk to the seller…
It gets drained faster than the older device V1 I have, even when used with the same cartridges.
I sent an email to the seller
