https://community.sony.no/t5/z-series/my-phone-automatically-shut-down-when-i-make-a-call/m-p/3410543#M66589 The problem was solved.<BR />By replacing the battery by a new one.<BR /><BR />After searching for the problem, I find that when lithium ion batteries are heated to a certain limit the reactions in the battery stops automatically when a heavy load occur on the battery by voltage rapid drainage due to call.<BR /><BR />I think when the phone opened, service center use excess of temperature to separate back cover from glue so the temperature increased in battery, this process is irreversible and battery must be changed, however actually it's in a healthy and excellent state.
