Hi, I have iphone 13 purchased on Sept 2022, currently battery at 77%. I went to service centre & those guys said we need your battery to be swollen for free replacement, to an extent that it should pop the screen.
I was like that could be threat, why are you guys even waiting for it?
She literally said this program is running all year long, just get your battery swollen up & get free replacement.
Any tips on how to get it done?
