I left my iPhone X to an Apple authorised service point to take advantage of the battery replacement program. They said it will take 2-3 days because they had to order the battery and speaker. I asked what was wrong with the speaker and how much that is going to cost? They replied that the speaker does not cost extra and it has to be changed together with the battery. I find weird that the speaker needs to change with the battery. Is this the case with the iPhone X?
