Hi, my tinymoight is like nearly two years old. For the last 6 months or longer, even if the last time it had four haptic pulses and was charged recently, when I go to use it again a while later (like an hour or 3 later) it will do the three quick vibrations , cut out and then turn off. That's even with a brand new battery. So like what is the go here? It is surely an issue with the unit itself and not the batteries? I will only get like 3 or so bowls before I need to charge it again, on a full charge. It is better if I have lots of bowls in quick succession, but if I let it rest and not charge for a few hours, I will get like one bowl (usually about 7 or 8 puffs) and then it dies. And in those instances, it often gives 4 vibrations for that one time and then just completely dies at the start of the next bowl. Is it time to upgrade to a new base unit?
