Yeah, I thought so too but I wasn't ready to void my warranty. I send it to Evolv and they told me that some Paranormal Devices, in particular, have this problem. It is just hard to guess if it is a hardware failure or a chip failure. I thought it was a cold soldered point but that can't be because it works perfectly for like 10 puffs after 10 hours without batteries.
Still thanks for your help.
I just thought it would be the best way to send it to Evolv because they are pros.
