Hi there, just today I discovered that my iPhone X screen is popping up from the case. Upon further inspection it appears to be a swollen battery. I am going to the apple store tomorrow but I was wondering if I will be getting a new replacement or would Apple replace the battery? And what would the cost be? The iPhone is out of warranty but it is still under 2 years old. Update: Just took it into the apple store today and the person that was helping me out replaced the the whole iPhone for free. Thanks for all the replies.
