It's the tristar. Gonna go ahead and guess it's from over use with an aftermarket charger cord, which the person blew the first battery, and then left it on the charger to continually use it, and the tristar has now failed. If you have experience with microsoldering, then this is a good answer, if not send it to a board repair shop. Many of them have a mail in service

According to you he used the iPhone 6s Plus with a power bank case it charge his phone always. That could coz the problem-- one more thing i do micro soldering but I want to know is the iPhone 6s and 6s plus Tristar same


@refectio is the tristar on 6S replaced by Tigris? If so is it compatible with 6S+?


The iPhone 6S/6S+ uses the 1610A3 version of Tristar.
