battery swelling
I am using iphone 5s, its performence is good, but recently i encountered that my back panel is cracking out due to battery swelling. I can feel the swelling when i slide my fingers on the back panel, panel has developed cracks rigth through the apple logo from top to bottom. As this is battery fault do i get any replacemet from apple service center or should i pay for the new battery ?
I dint expect even apple products would have such problems, I am very perticular about using my charger, i use only apple charger that is given with the phone at the time of purchasel. How can i solve this issue ?
iPhone 5s, iOS 10.2.1, gold
