Yeah I'm just gonna go to Apple and get it replaced. I honestly thought it was way more expensive to get apple to replace it, but on their website it estimates $80 in my country. That's literally what I paid for the non-genuine apple repair. Am I missing some hidden costs?? I really thought it was like double the price

EDIT: My closest Apple Authorized Repair shop quotes $130 for an 11pro battery replacement. Whatevs. If there 1year warranty I can always come back if the fucker starts swelling again

Yes I've replaced phone batteries at this place with several older phones without any problems. And I've always used nonapple batteries because it was cheaper and they have always worked perfectly fine until now.
