Hello. I have an iPhone 6s that does not charge and it does not turn on. Only when I insert a new battery turns the iPhone on. When the battery runs out I have to put another. The battery is discharging quickly. I think the bug will be in the charging chip tristar, but I do not know for sure. Somebody have some experience with this problem? Thank you for answear. Simon.
Fast discharge and no charging are symptoms of a defective Tristar. A properly working phone will show an Apple logo and boot loop. If the Tristar IC is bad then the phone will not do anything.
