In my Iphone battery defect was there.I went many times in care but they don't understood this problem.Because it was may be manufacturing defect.So after long time they repaired.They changed display assembly and returned to me.This issue they didn't resolve and create new issue in display.They mashed up my phone display.Even they are not replacing my phone.If they don't understand the battery problem they have to replace it.But i don't know fool engineers are there.I was thinking to give the iphone 7 to my dad and brother as a gift.But now i got apple has worst service so now i will not buy iphone 7.Your service is the worst service.
