I purchased a joye Ego starter system with two 1000v batteries. I vape all the time. So I'm a super heavy user. I've checked all the information on this forum I can find and haven't seen this addressed. Over the three months I've been using the system, the batteries seemed to stop holding their charge as long. And it seemed like they weren't creating the vapor I was accustomed to getting. Maybe it's my imagination, but it seems like as the battery power fades the quality of the vapor reduction becomes poorer. When new that period of time at the end of the charge was relatively short, but the longer I had the batteries, that end time grew longer, and the batteries began to die much more quickly. Finally, I bought new ones and just threw the old ones away. It seems like the cycle is beginning again though. I also bought a pass through system, that I love! Anyone else have this problem. I can't afford to buy two new batteries every three months at $22/a pop.
