Ask him if anything happened to the phone before it happened. Or did it suddenly happen for no apparent reason?

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

@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.
