Are you thinking about the Samsung phones rather than iPhones? I think they stopped making them shortly after the fires happened. I'm afraid that I was no longer involved in lithium battery packs at that stage so I've not looked into the causes. I tried digging out the paper where I saw the stats on cell faults related to charge state but I can't find it at the moment.
