iPhone 14 Pro battery swelling twice within a year

Battery has swollen last year not even 8 or 9 months after buying a new phone... then I changed it with a fake one cause the original was expensive and now not even a year from changing this one has swollen again. iPhone 14 Pro. terrible expirience. Also on the original one battery health dropped 90% within first 7 months.
