I've had my Trifecta 3-in-1 for about six months and love it. The past few days though the battery sometimes fires off by itself or after I vape it just keeps firing (I keep it on automatic mode mostly). The manual button isn't touching anything else when this happens. I've had to unscrew the cart to make sure it doesn't burn when I'm not vaping. Has this happened to anyone else? Does this mean that my battery is dying?
