hey there everyone I wanted to ask this question I have been using my ikonn 220 and really love it but I charge it every night before I go to sleep and then the next day use it all day and do the same thing but the guy told me to take the batteries out and switch around and put back in and then charge it. And he said it’s fine to charge it over night. And tonight I noticed when I moved it. It was like Luke warm. Not hot or anything just warm. And I wanted to ask you guys if that’s normal for it to be warm because I know in the morning when I get up it’s not warm at all. I appreciate everyone’s help. And still vaping and have not touched cigarettes for 3 weeks now..
